The <strong>Environment</strong>al Information System (ENVIS) Centre at the Wildlife Institute<br />

<strong>of</strong> <strong>India</strong>, set up in September 1997, is part <strong>of</strong> the ENVIS setup <strong>of</strong> the Ministry <strong>of</strong><br />

<strong>Environment</strong> <strong>and</strong> Forests, Government <strong>of</strong> <strong>India</strong>. It deals with general matters<br />

concerning ‘wildlife’ <strong>and</strong> specifically those related to ‘protected areas’. Its<br />

objectives are to:<br />

♦ Establish a data bank on information related to wildlife <strong>and</strong> wildlife<br />

protected areas, <strong>and</strong> thereby build up a repository <strong>and</strong> dissemination centre<br />

for information on wildlife science;<br />

♦ Promote national <strong>and</strong> international cooperation, <strong>and</strong> exchange <strong>of</strong> wildlife<br />

related information;<br />

♦ Provide decision makers at the apex level with information related to<br />

conservation <strong>and</strong> development<br />

ENVIS Bulletin Vol. 10 No. 1, 2007: Galliformes <strong>of</strong> <strong>India</strong><br />

It was most kind <strong>and</strong> thoughtful <strong>of</strong> you to send me the formidable <strong>and</strong> beautifully brought out copy <strong>of</strong> the<br />

ENVIS publication <strong>and</strong> CD on the 'Galliformes <strong>of</strong> <strong>India</strong>'. I have been much enjoying the past month<br />

rummaging through the stupendous mine <strong>of</strong> information, with lovely illustrations <strong>of</strong> a species in those<br />

early years over two decades ago when we feared their rapid extinction. It is so reassuring to see so much<br />

research since done to show that these so-called 'game birds' are secure <strong>and</strong> largely in good health.<br />

I am really happy to have a copy <strong>of</strong> this splendid labour <strong>of</strong> love, put together with such meticulous care<br />

skill <strong>and</strong> pr<strong>of</strong>essionalism, <strong>and</strong> feel short <strong>of</strong> words in praise <strong>of</strong> a monumental work by so many dedicated<br />

contributors. Dr. Sathyakumar's editing, as always, in the N<strong>and</strong>a Devi tradition if I may say so, along with<br />

Dr. K. Sivakumar, has been superb. I am particularly delighted that you focused among avian species on<br />

the Galliformes, which includes on the cover our National bird, the dancing Peacock!<br />

My warmest congratulations to your WII team - I feel so privileged <strong>and</strong> proud to have been closely<br />

associated with the creation almost three decades ago <strong>of</strong> a great institution doing such splendid work in<br />

building knowledge <strong>and</strong> thus helping to save our natural world.<br />

N.D. Jayal, Former Secretary<br />

Ministry <strong>of</strong> Agriculture, Govt. <strong>of</strong> <strong>India</strong>, Vasanth Vihar, Dehradun, <strong>India</strong><br />

It looks like an excellent publication <strong>and</strong> my compliments to WII in this regard. My only comment is<br />

that the publication would have had an added more value if the sub-species <strong>and</strong> their distribution had<br />

also been mentioned in brief. This would particularly apply to a species like the Kalij Pheasant.<br />

Dr. M.K. Ranjitsinh<br />

Wildlife Trust <strong>of</strong> <strong>India</strong>, New Delhi, <strong>India</strong><br />

This document provides a brilliant reference for those seeking to conserve the Galliformes <strong>of</strong> <strong>India</strong> as it<br />

summarizes the work carried out so far <strong>and</strong> gives guidance <strong>and</strong> ideas <strong>of</strong> what should be done to conserve<br />

this important group <strong>of</strong> birds in <strong>India</strong> in the future. I congratulate you for this great achievement <strong>and</strong> look<br />

forward to receive copies <strong>of</strong> further series that hopefully will be published in the future.<br />

Dr Francis Buner, Grey Partridge Ecologist<br />

Game & Wildlife Conservation Trust<br />

Fordingbridge, Hants, SP6 1EF, United Kingdom<br />

It is a wonderful work that will be useful to many conservationists not only in <strong>India</strong> but also over the<br />

world. I'm preparing a book about Partridge, Quails <strong>and</strong> Francolins <strong>and</strong> I found already new information<br />

in this CD. Our century will be probably the conservation century for the threatened species <strong>and</strong> I'm<br />

pleased to see that now the conservationists originate from the countries where these species live.<br />

Congratulations to you <strong>and</strong> to all participants in this work. I wish you a Happy New Year with many<br />

successes in the conservation <strong>of</strong> the <strong>India</strong>n Galliformes.<br />

EEP Coordinator for the Edwards' Pheasant, European Studbookeeper for the Crestless Fireback<br />

Many thanks for the wonderful overview on Galliformes <strong>of</strong> <strong>India</strong>. I was very impressed. My best wishes<br />

for your future work.<br />

Dr. Siegfried Klaus<br />

Lindenhöhe 5, D-07749 Jena, Germany


I have gone through the CD on the 'Galliformes <strong>of</strong> <strong>India</strong>' that has depicted your excellent country's<br />

beautiful birds. It has been nicely prepared <strong>and</strong> the information in the bulletin is very helpful for our<br />

study. But I wonder why the information on the incubation period <strong>of</strong> Chukar (Alectoris chukar) has been<br />

mentioned as 'unknown' in the bulletin. I wish to inform you that we have been studying Chukar <strong>and</strong><br />

Rock partridge since 1995 <strong>and</strong> have found that the incubation period for Chukar is 23-24 days. The<br />

results <strong>of</strong> our study are available in the internet now <strong>and</strong> the same may be included in the bulletin.<br />

Dr. Alper Yilmaz,<br />

University <strong>of</strong> Selcuk, Turkey.<br />

This is a path breaking effort <strong>and</strong> I am sure there will be many more additions to the series in time to<br />

come. Congratulations! This one that I have received will find a pride <strong>of</strong> place in my small library once I<br />

am through.<br />

D. Datta Roy, Former Chief Wildlife Warden,<br />

Tripura, Bagdogra, West Bengal, <strong>India</strong><br />

I can not resist complimenting you <strong>and</strong> your dedicated team to have produced such a valuable book on<br />

'Galliformes <strong>of</strong> <strong>India</strong>'. Your project leader Sh. P.R. Sinha deserves "kudos" for encouraging <strong>and</strong> inspiring<br />

the scientists to bring out such scientific literature. The get up <strong>and</strong> design <strong>of</strong> the bulletin is attractive in<br />

addition to almost errorless printing. I appreciate the really exhaustive bibliography, so strenuously<br />

prepared. The color pictures <strong>of</strong> birds <strong>and</strong> their distribution maps are nicely depicted.<br />

V.S. Saxena, IFS (R)<br />

Member Appellate Authority Pollution Control, Government <strong>of</strong> Rajasthan, <strong>India</strong><br />

It is an excellent document. I want to congratulate all your staff for bringing out this valuable document.<br />

It is a rich source <strong>of</strong> reference for researchers like me. I think it should be widely distributed to Institutes<br />

<strong>and</strong> Universities.<br />

Dr. Asad Rahmani<br />

Director, Bombay Natural History Society, Mumbai, <strong>India</strong><br />

We found 'Galliformes <strong>of</strong> <strong>India</strong>' to be extremely useful. We would like to congratulate you <strong>and</strong> your team<br />

for bringing out this bulletin.<br />

Manoj Kumar Misra, Executive Director,<br />

PEACE Institute Charitable Trust, Delhi, <strong>India</strong><br />

My congratulations to you <strong>and</strong> your team in WII-ENVIS, Dr. S. Sathyakumar <strong>and</strong> Dr. K. Sivakumar on<br />

producing a great volume on 'Galliformes <strong>of</strong> <strong>India</strong>'. It speaks greatly about the planning <strong>and</strong> hard work<br />

that has been put in. The design, color plates <strong>and</strong> layout <strong>of</strong> the printed volume as well as the CD is superb.<br />

Dr. Rajiv S. Kalsi, Head, Department <strong>of</strong> Zoology<br />

M.L.N. College, Yamuna Nagar, Haryana, <strong>India</strong><br />

It is a nice review <strong>of</strong> the status <strong>and</strong> distribution <strong>of</strong> the group in the country. Congratulations to you, Dr.<br />

S. Sathyakumar <strong>and</strong> Dr. K.Sivakumar <strong>and</strong> the reviewers for putting this together.<br />

The publication is extremely informative <strong>and</strong> beautifully done.<br />

DIRECTOR’S NOTE<br />

Wildlife Institute <strong>of</strong> <strong>India</strong> is one <strong>of</strong> the ENVIS Centres <strong>of</strong> Ministry <strong>of</strong><br />

<strong>Environment</strong> & Forests, Government <strong>of</strong> <strong>India</strong> for publication <strong>and</strong> dissemination <strong>of</strong><br />

researched information in the subject area <strong>of</strong> Wildlife <strong>and</strong> Protected Areas. So far, it has<br />

brought out 10 thematic ENVIS bulletins. These bulletins are available as hardcopies <strong>and</strong><br />

CDs, <strong>and</strong> are also hosted on Institute's website http:wii.gov.in/envis/publications.html.<br />

Considering the importance <strong>of</strong> the floral wealth <strong>of</strong> the country, this publication on "<strong>Special</strong><br />

<strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong>" covering various Biogeographic zones <strong>of</strong> the country<br />

has been compiled. It is an attempt to make its readers aware about the varied <strong>and</strong> unique<br />

floral wealth <strong>of</strong> our country <strong>and</strong> draw their attention towards the threat to their long term<br />

persistence as part <strong>of</strong> our natural ecosystem.<br />

It is hoped that nature lovers <strong>and</strong> protected area managers would find the information contained<br />

in this publication very useful. It would also help policy makers <strong>and</strong> pr<strong>of</strong>essional managers in<br />

developing appropriate strategies for conservation <strong>and</strong> monitoring <strong>of</strong> the plants species <strong>and</strong><br />

their habitats.<br />

FOREWORD<br />

<strong>India</strong> with vast geographical expanse <strong>and</strong> amazing diversity in climate, soil <strong>and</strong> topography support almost<br />

all types <strong>of</strong> ecosystems found anywhere in the world. The varied ecosystems span from the alpine grassl<strong>and</strong>s<br />

<strong>of</strong> Himalayas to coastal mangroves <strong>of</strong> Sundarbans; hot deserts <strong>of</strong> Rajasthan to tropical evergreen <strong>and</strong> semi<br />

evergreen forests <strong>of</strong> North-East <strong>and</strong> Western Ghats; the flood plains <strong>of</strong> Gangetic belt to coral reefs <strong>of</strong><br />

Andaman sea; the cold deserts <strong>of</strong> Ladakh <strong>and</strong> Lahaul -Spiti to tropical Isl<strong>and</strong> ecosystems Andaman &<br />

Nicobar Isl<strong>and</strong>s, <strong>and</strong> so on. In each <strong>of</strong> these ecozones there are hundreds <strong>of</strong> biotopes- each supporting its<br />

distinctive floristic components. The confluence <strong>of</strong> three major biogeographical realms (Eurasian, Afro-<br />

tropical <strong>and</strong> Indo-Malayan) has further enhanced the intermingling <strong>of</strong> floristic elements <strong>of</strong> these regions<br />

in <strong>India</strong>n flora. Though the country constitutes merely 2% <strong>of</strong> the world’s geographical area, it harbors ca<br />

45000 species, nearly 11% <strong>of</strong> the known world flora, <strong>and</strong> thus ranking third in Asia <strong>and</strong> eleventh among the<br />

top mega-diversity countries <strong>of</strong> the world. Studies undertaken so far on floras in several parts <strong>of</strong> the world<br />

have shown that many plant species are in danger <strong>of</strong> extinction while some have turned extinct. On a global<br />

basis, the IUCN have estimated that about 10% <strong>of</strong> world’s vascular plant species are under varying degrees<br />

<strong>of</strong> threat <strong>and</strong> started publication <strong>of</strong> Red Data Books on animals <strong>and</strong> plants to include data on threatened<br />

species <strong>and</strong> facilitate their conservation.<br />

In <strong>India</strong>, the problem on threatened plants was first discussed in the 11th Technical Meeting <strong>of</strong> the IUCN<br />

in 1969 in which important papers were presented on the subject. Subsequently, the Botanical Survey <strong>of</strong><br />

<strong>India</strong> published a small book-let: <strong>Threatened</strong> plants <strong>of</strong> <strong>India</strong>- A State-<strong>of</strong>-the Art Report, in 1980. Concerted<br />

efforts were made on the subject <strong>and</strong> valuable base-line data on nearly 1000 threatened species gathered,<br />

all this data had given impetus for writing up <strong>of</strong> Red Data Books by the Botanical Survey. Endemicity <strong>and</strong><br />

xv


usefulness leading to overexploitation are essentially two reasons for a species to come under threat. Apart<br />

from it, rapid changes in l<strong>and</strong> use have resulted in degradation <strong>of</strong> specialized natural habitats <strong>and</strong> along<br />

with it rapid depletion <strong>of</strong> plants confined to these habitats.<br />

<strong>Special</strong>ized habitats <strong>and</strong> threatened plants undeniably deserve exceptional concern for endured conservation<br />

<strong>and</strong> sustained monitoring in different phytogeographic regions in the country. Shared collaboration,<br />

coordination <strong>and</strong> harmonization among institutions <strong>and</strong> also among naturalists, plant taxonomists, forest<br />

<strong>and</strong> protected area managers <strong>and</strong> volunteers possibly give the essential boost to realize this objective. I am<br />

happy to know that the Wildlife Institute <strong>of</strong> <strong>India</strong> has taken an initiative to bring out a special issue<br />

focusing on the theme ‘<strong>Special</strong>ized <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong>. The articles in this issue are contributed<br />

by pr<strong>of</strong>essional taxonomists as well as amateur naturalists in the country <strong>and</strong> covered Western Himalayas,<br />

North East <strong>India</strong> <strong>and</strong> also Western <strong>and</strong> Eastern Ghats. Thar Desert, Ran <strong>of</strong> Kachchh, <strong>and</strong> some semi arid<br />

regions <strong>of</strong> Deccan are also covered. Many threatened species <strong>and</strong> their habitats are discussed. Undeniably,<br />

this is a beginning for a focused documentation on specialized habitats <strong>and</strong> threatened species but certainly<br />

not an exhaustive account in view <strong>of</strong> the vastness <strong>and</strong> diversity <strong>of</strong> the country. This will act as a stimulant to<br />

similar such publications.<br />

I am sure, this publication would prompt personnel manning forest <strong>and</strong> protected areas to take up follow up<br />

measures recommended for different biogeographic zones <strong>and</strong> also specific to species to strengthen plant<br />

conservation efforts in the country.<br />

Monitoring <strong>Threatened</strong> <strong>Plants</strong> <strong>and</strong> Their <strong>Habitats</strong>:<br />

Way Forward<br />

- Editorial<br />

Conscious <strong>of</strong> current conservation crisis, a number <strong>of</strong> leading institutions <strong>and</strong><br />

individuals are currently engaged in the systematic study <strong>of</strong> flora <strong>and</strong> fauna including threatened<br />

species. The responsibility <strong>of</strong> implementing in situ conservation <strong>of</strong> biodiversity is primarily vested with<br />

the State Forest Departments (SFDs) which have the backing <strong>of</strong> several policy documents including<br />

recently notified Biodiversity Act (2002) <strong>and</strong> technical support <strong>of</strong> research institutions. Though a<br />

considerable effort has been made to strengthen the protected area network (PAN) in the country<br />

(4.8% <strong>of</strong> the geographical area), all habitats, threatened plants <strong>and</strong> ecologically sensitive areas cannot<br />

be contained within the PAN. The PA boundaries in the past were decided based on administrative<br />

convenience rather than ecological considerations. As a result, several macro <strong>and</strong> microhabitats which<br />

harbour unique assemblages <strong>of</strong> plants remain outside the current PAN <strong>and</strong> continue to face<br />

anthropogenic pressures.<br />

Generally, well managed parks ensure conservation <strong>of</strong> major ecosystems <strong>and</strong> representative biota.<br />

However, conservation <strong>of</strong> rare <strong>and</strong> threatened plants requires concerted efforts <strong>and</strong> baseline information.<br />

As part <strong>of</strong> conservation planning <strong>and</strong> habitat management activities the PA managers are required to<br />

know about the plants <strong>of</strong> high conservation value but this is not taken into consideration in all the<br />

parks due to lack <strong>of</strong> floral inventory <strong>and</strong> paucity <strong>of</strong> information on rare endemic species. Conservation<br />

<strong>of</strong> gene pool <strong>and</strong> native crop varieties are <strong>of</strong>ten recommended in the Biosphere Reserves but precious<br />

little has been achieved in this direction so far. Very few PAs have been set aside exclusively for the<br />

conservation <strong>of</strong> floral diversity. Even prioritized areas lack trained manpower <strong>and</strong> adequate ecological<br />

information on rare <strong>and</strong> vulnerable species. More <strong>of</strong>ten than not, interested staff do not get involved in<br />

the search <strong>and</strong> protection <strong>of</strong> such plants due to lack <strong>of</strong> incentives, initiatives <strong>and</strong> relevant literature.<br />

Therefore, despite having enormous conservation potential, most <strong>of</strong> the PAs <strong>and</strong> other forests are<br />

unable to play an active role in the restoration <strong>and</strong> conservation <strong>of</strong> threatened, rare <strong>and</strong> endemic<br />

plants, which could be <strong>of</strong> local, regional or global interest.<br />

In order to promote practical plant conservation <strong>and</strong> monitoring in various Biogeographic zones <strong>of</strong><br />

<strong>India</strong>, it is high time that we initiate an all <strong>India</strong> coordinated programme on monitoring <strong>and</strong> restoration<br />

<strong>of</strong> highly threatened plants. The programme would need the involvement <strong>of</strong> leading institutions <strong>and</strong><br />

taxonomists, SFDs, Universities <strong>and</strong> Volunteers. This would help in the following ways: (i)<br />

xvii


Establishment <strong>of</strong> linkages between the Field Botanists <strong>and</strong> frontline staff <strong>of</strong> SFDs; (ii) Restoration,<br />

habitat improvement, protection <strong>and</strong> monitoring <strong>of</strong> threatened taxa on priority basis; <strong>and</strong> (iii)<br />

Strengthening biodiversity conservation in various Biogeographic zones <strong>of</strong> the country. At the outset,<br />

such an initiative would require identification <strong>of</strong> rare <strong>and</strong> threatened species <strong>and</strong> habitats <strong>and</strong> major<br />

threats to such species, priority listing for in-situ conservation, <strong>and</strong> restoration. Following this, the<br />

participants or the collaborating agencies will need to carry out status surveys <strong>of</strong> selected taxa within<br />

<strong>and</strong> outside the PAs, identification <strong>of</strong> the restoration sites in consultation with the SFDs <strong>and</strong> identified<br />

botanists. The third <strong>and</strong> most important step would be to evolve appropriate monitoring protocols for<br />

various species through a series <strong>of</strong> training workshops in the field involving SFDs (Range Officers or<br />

equivalent staff) in which identity <strong>of</strong> species, survey methods, restoration <strong>of</strong> microsites, <strong>and</strong> baseline<br />

data collection for future monitoring can be ascertained. Preparation <strong>of</strong> distribution maps <strong>and</strong><br />

information on the micro-habitats for various areas <strong>and</strong> further analysis in GIS domain may be achieved<br />

within a stipulated time.<br />

In this issue <strong>of</strong> ENVIS Bulletin, we have made an attempt to collate information on special habitats<br />

<strong>and</strong> threatened plants needing further monitoring <strong>and</strong> restoration in different Biogeographic zones <strong>of</strong><br />

<strong>India</strong>. Altogether, there are thirty three articles covering various biogeographic regions <strong>of</strong> the country.<br />

In addition, there are two short notes (Box items) <strong>and</strong> a compendium <strong>of</strong> selected references on<br />

threatened <strong>and</strong> endangered plants <strong>of</strong> <strong>India</strong>. The contributors range from amateur naturalists to senior<br />

foresters <strong>and</strong> pr<strong>of</strong>essional botanists. It is hoped that this volume would enthuse naturalists <strong>and</strong> amateur<br />

botanists to take up further monitoring <strong>and</strong> documentation <strong>of</strong> threatened plants in their respective<br />

regions <strong>and</strong> this will serve as a much needed baseline information for the field staff <strong>of</strong> SFDs.<br />

Located in the rain shadow <strong>of</strong> the Great Himalayan massif, Ladakh forms a major portion <strong>of</strong> the <strong>India</strong>n Trans-Himalaya.<br />

Also known as ‘Little Tibet’, this region is spread over some 96,700 km 2 area in the state <strong>of</strong> Jammu & Kashmir. The<br />

region exhibits typical biophysical features <strong>of</strong> cold deserts having low precipitation <strong>and</strong> mean annual temperature,<br />

short growing season, low primary productivity <strong>and</strong> sparse vegetation cover. Biogeographically, it is divisible into two<br />

provinces viz., Ladakh Mountains <strong>and</strong> Eastern Plateau (Rodgers & Panwar 1988). The former includes rugged mountain<br />

ranges <strong>and</strong> valleys while the latter is gently undulating elevated l<strong>and</strong>scape that forms the western extension <strong>of</strong> Tibetan<br />

Plateau (Plate 1). Floristically, Ladakh is not as rich as comparable altitudes <strong>of</strong> Greater Himalaya, but it supports a<br />

unique assemblage <strong>of</strong> flora having close affinity with Central Asia <strong>and</strong> Tibetan plateau. The region has an enormous<br />

variation in altitude (2600 to >6500 m asl). Snowline in the Trans-Himalaya is located at much higher altitude (5800 –<br />

6000 m) as compared to Greater Himalaya where it is usually around 5500 m. This provides adequate area for the<br />

plants <strong>of</strong> high alpine <strong>and</strong> sub-nival zone. The interface between the moist alpine zone <strong>of</strong> Greater Himalaya <strong>and</strong> the cold<br />

arid region is generally sharp. Mean annual precipitation varies from 50 to 150mm <strong>and</strong> it increases at higher altitudes,<br />

while deep river valleys such as lower Nubra <strong>and</strong> Zanskar are particularly dry. The arid l<strong>and</strong>scape is interspersed with<br />

glacial streams, rivers <strong>and</strong> lake basins which form crucial Life -Support System for all living forms <strong>and</strong> provide ecosystem<br />

services. Geologically, Ladakh is quite diverse <strong>and</strong> divisible into several zones, each comprising a series <strong>of</strong> formations<br />

<strong>and</strong> sedimentary sequences ranging in age from recent to Cretaceous period which have undergone complex tectonic<br />

evolution (Frank et al. 1977, Thakur & Rawat 1992). In the extreme west there are basaltic formations (Dras volcanics),<br />

while in the north-eastern parts one comes across the remnant Tethyan sea beds.<br />

Based on extensive floristic surveys, Kachroo et al. (1977) have reported 611 species <strong>of</strong> flowering plants from Ladakh.<br />

However, recent estimates suggest that the number may be much higher. Dickore & Miehe (2002) estimate that for<br />

most <strong>of</strong> the ladakh the richness <strong>of</strong> vascular plants may be about 500-1000 species per 10,000 km 2 , while in Karakoram<br />

<strong>and</strong> north-eastern Ladakh the plant species richness is much lower i.e.,

distribution across all the habitats. Here, only a few examples <strong>of</strong> special l<strong>and</strong>forms <strong>and</strong> corresponding vegetation types<br />

have been described. These ‘<strong>Special</strong> <strong>Habitats</strong>’ reflect peculiar ecological settings <strong>and</strong> harbour unique plant<br />

assemblages including some <strong>of</strong> the rare <strong>and</strong> threatened species (Plate 1).<br />

i. Moist meadows Zanskar Ranges<br />

The areas immediately north <strong>of</strong> Greater Himalaya, especially in the moist pockets <strong>of</strong> Zanskar range <strong>and</strong> northern<br />

slopes <strong>of</strong> Nun Kun, Kolahoi <strong>and</strong> Zoji La are characterized by the presence <strong>of</strong> moist meadows rich in herbaceous flora.<br />

The basins <strong>of</strong> larger mountains e.g., Surru, Kargil <strong>and</strong> Dras, especially towards higher slopes receive higher snow<br />

during winter which support extensive grassy slopes dominated by Festuca kashmeriana, Oryzopsis munroi <strong>and</strong><br />

Melica persica. Moist slopes harbour a rich array <strong>of</strong> medicinal <strong>and</strong> aromatic plants including Ephedra gerardiana,<br />

Podophyllum hex<strong>and</strong>rum, Inula rhizocephala, Iris ensata, Swertia speciosa, Arnebia euchroma, Bistota affinis, Cicer<br />

microphyllum, Geranium grevilleanum, Allium carolinianum <strong>and</strong> Rheum australe to name a few. Pulsatilla wallichiana,<br />

one <strong>of</strong> the little known anemones, can be seen occasionally on these slopes. Colchicum luteum, a valuable medicinal<br />

herb is found in moist meadows around Dras.<br />

ii. Marsh meadows <strong>of</strong> Changthang<br />

Several lake basins <strong>and</strong> seasonally inundated banks <strong>of</strong> Indus in Changthang have given rise to lush green marsh<br />

meadows which are patchy but rich in plant life. Pools <strong>of</strong> shallow water support a number <strong>of</strong> aquatic species such as<br />

Potamogeton pectinatus, Myriophyllum verticillatum, Hippuris vulgaris, Ranunculus natans <strong>and</strong> R. trichophyllus. The<br />

marsh meadows are dominated by sedges (species <strong>of</strong> Carex, Blysmus, Kobresia <strong>and</strong> Eleocharis) <strong>and</strong> a few grasses<br />

e.g., Calamogrostis holciformis, Poa spp., Puccinellia spp. Typical herbaceous elements in marsh meadows include<br />

species <strong>of</strong> Ranunculus, Pedicularis, Gentiana, Gentianella <strong>and</strong> Primula. Some <strong>of</strong> the species, typical <strong>of</strong> saline marshes<br />

(halophytes) are Atriplex tatarica, Pucinellia himalaica, Suaeda olufsenii, Triglochin maritimum <strong>and</strong> Glaux maritima.<br />

Rawat & Adhikari (2005) have identified several communities along moisture gradients in Tso Kar basin, Changthang.<br />

iii. Craggy Rock Surfaces in Zanskar<br />

A few pockets in the Zanskar range exhibit special lithological features making them unique. For example, higher<br />

slopes <strong>of</strong> Naki La, adjacent to Lachung La that rise abruptly above Yunam River consist <strong>of</strong> monotonous, phyllitic, olive<br />

coloured shales with fine graded s<strong>and</strong>stones intermingled with ‘exotic’ limestone. Geologically such areas correspond<br />

with Namik La Flysch. Floristically such areas are quite diverse <strong>and</strong> interesting. Among the rocky crags <strong>of</strong> Naki La<br />

(eastern Zanskar) the plant communities comprise dwarf Isopyrum anemonoides, Silene viscosa, Minuarta biflora,<br />

Valeriana himalayana, Rhodiola fastigiata, Saxifraga spp., Biebersteinia odora <strong>and</strong> Festuca kashmiriana to name a<br />

few.<br />

iv. Scree bases<br />

Scree bases (colluvial deposits) <strong>and</strong> tallus along valley bottoms in Zanskar <strong>and</strong> other parts <strong>of</strong> Western Ladakh represent<br />

yet another special habitat. Such areas, usually parallel to stream or river courses, harbour several characteristic<br />

species e.g., Lamium rhomboideum, Corydalis crassifolia, C. moorcr<strong>of</strong>tiana, Astragalus nivalis, Oxytropis tatarica,<br />

Rheum tibeticum, Elymus nutans, Aquilegia fragrans, Thermopsis inflata <strong>and</strong> Silene hispida. It appears that most <strong>of</strong><br />

these species are dispersed mechanically along with loose cobbles <strong>and</strong> are well adapted to grow in such habitats.<br />

Some <strong>of</strong> the species viz., C. crassifolia, T. inflata <strong>and</strong> A. nivalis have typically swollen or inflated fruits to aid wind<br />

dispersal along valley bottoms.


v. Riverine Scrub<br />

Two species <strong>of</strong> Hippophae, viz., H. rhamnoides ssp. turkistanica <strong>and</strong> H. tibetana form major constituents <strong>of</strong> riverine<br />

scrub in Ladakh. While the former is much taller (>1 m) <strong>and</strong> forms dense thickets along the banks <strong>of</strong> Indus, Shyok <strong>and</strong><br />

Nubra rivers, the latter, a dwarf (

Ladakh lies at the cross roads <strong>of</strong> floral migration between Central Asia <strong>and</strong> Greater Himalaya. Therefore, the level <strong>of</strong><br />

endemism in the flora <strong>of</strong> Ladakh is relatively low (

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

A perennial bulbous herb. Leaves shorter than scape, cylindrical hollow. Scape 10-40 cm, cylindrical, covered with leaf<br />

sheaths only at base. Umbels globose, densely many flowered. Perianth pink to red or dark purple. Filaments equal, 1.5<br />

-2 times as long as perianth segments, connate at base <strong>and</strong> adnate to perianth segments. Ovary globose, without<br />

concave nectaries at base. Style much longer than ovary, exserted. Fls. <strong>and</strong> Frs. June – September.<br />

Dry, open scrub <strong>and</strong> rock crevices between 4000 - 4800 m. Leaves collected locally to prepare condiments <strong>and</strong> also<br />

used medicinally. Distributed in Pakistan, <strong>India</strong> (Karakoram <strong>and</strong> Ladakh ranges), Nepal <strong>and</strong> China (Tibet). The species<br />

is locally collected but also protected in agricultural fields in Durbuk <strong>and</strong> Nubra Valleys.<br />

5. Arnebia euchroma (Royle) Johnston (Boraginaceae)<br />

Local Name : Dimmok, Aambokh<br />

Perennial herbs with dense stiff hairs <strong>and</strong> thick root stock. Basal leaves long, linear. Upper leaves shorter <strong>and</strong> broader.<br />

Flowers pink or purplish white in terminal dense (globular) racemes. Occasional on dry s<strong>and</strong>y / stony slopes 3500 –<br />

4500 m asl. Roots yield purple dye which is mixed with oil <strong>and</strong> used as hair tonic. The roots are also used as ingredient<br />

<strong>of</strong> Amchi medicine for the treatment <strong>of</strong> cough, backache <strong>and</strong> several other ailments.<br />

Rocky <strong>and</strong> gravelly slopes. Distributed in Afghanistan, NW <strong>India</strong>, Kazakhstan, Kyrgyzstan, Nepal, Pakistan, Russia,<br />

Tajikistan, Turkmenistan <strong>and</strong> Uzbekistan. Over extraction for local as well as commercial use is the major cause <strong>of</strong> its<br />

decline.<br />

Conservation Measures<br />

Most <strong>of</strong> the high value <strong>and</strong> threatened species <strong>of</strong> Ladakh including those listed above, can best be conserved with the<br />

help <strong>of</strong> local institutions such as Amchi Association <strong>of</strong> Ladakh, Women’s Alliance <strong>of</strong> Ladakh <strong>and</strong> other Self Help<br />

Groups. The Department <strong>of</strong> Forest <strong>and</strong> Wildlife needs to initiate dialogues with such organizations to identify <strong>and</strong> set<br />

aside a few localities in different watersheds where natural habitats can be protected <strong>and</strong> restored in order to promote<br />

natural regeneration <strong>of</strong> high value medicinal plants. Amchis <strong>and</strong> their collectors would be the best judges to set the<br />

limits <strong>of</strong> harvest for various species on a sustainable basis. A network <strong>of</strong> medicinal plant conservation areas (MPCAs)<br />

needs to be established across Ladakh so as to ensure the in-situ conservation <strong>of</strong> medicinal <strong>and</strong> associated threatened<br />

plants.<br />

The l<strong>and</strong>scape immediately north <strong>of</strong> main central thrust (MCT) in the state <strong>of</strong> Uttarakh<strong>and</strong> represents a unique cold<br />

arid ecosystem that has largely escaped the attention <strong>of</strong> the ecologists, geographers <strong>and</strong> natural resource managers,<br />

owing to the remoteness, inaccessibility <strong>and</strong> harsh climatic conditions. This area forms a narrow strip (50 – 80 km<br />

wide) between the crest <strong>of</strong> Greater Himalaya <strong>and</strong> water divide between Satluj <strong>and</strong> Yarlung-Tsangpo that also forms the<br />

international boundary between <strong>India</strong> <strong>and</strong> Tibet (Valdiya 2001, Mazari 2007). One <strong>of</strong> such valleys in the state is Nilang<br />

(31 o 00 44.1" to 31 o 27' 06.26" N latitudes <strong>and</strong> 78 o 53' 39" to 79 o 15" E longitudes), located in Uttarkashi District. It is<br />

spread over an area <strong>of</strong> about 1100 km 2 <strong>and</strong> forms the entire catchment <strong>of</strong> the river Jahnavi or Jad Ganga <strong>and</strong> its<br />

tributaries. Biogeographically, the Nilang Valley exhibits close affinities with the Tibetan Plateau both in terms <strong>of</strong><br />

proximity <strong>and</strong> species composition. Although, Rodgers <strong>and</strong> Panwar (1988) had categorized the entire region <strong>of</strong><br />

Uttarakh<strong>and</strong> (erstwhile Uttar Pradesh) under Western Himalaya (2B), this area can safely be categorized into Trans-<br />

Himalaya (Zone 1). However, owing to rapid transition between the Greater Himalaya (2B) <strong>and</strong> juxtaposition <strong>of</strong> valleys<br />

<strong>and</strong> varied topography it is rather difficult to mark sub-division <strong>and</strong> characteristics <strong>of</strong> any provinces within zone A.<br />

Presence <strong>of</strong> snow leopard (Uncia uncia), blue sheep (Pseudois nayaur), historical presence <strong>of</strong> wild yak (Bos grunniens),<br />

seasonal movement <strong>of</strong> great Tibetan sheep (Ovis ammon), characteristic cold arid steppe vegetation <strong>and</strong> dominance<br />

<strong>of</strong> floral elements similar to Ladakh <strong>and</strong> Tibetan Plateau qualifies this area to be classified under <strong>India</strong>n Trans-<br />

Himalaya.<br />

Historical account <strong>of</strong> Nilang Valley is given by Atkinson (1981 Rep.). The original inhabitants <strong>of</strong> this valley (Jadhs) were<br />

resettled at lower altitudes viz., Harsil <strong>and</strong> Dunda following Chinese aggression in north <strong>India</strong> in 1962. Presently this<br />

area forms a part <strong>of</strong> Gangotri National Park .<br />

This article highlights the botanical wealth <strong>and</strong> a few species <strong>of</strong> high conservation significance from Nilang Valley.<br />

The L<strong>and</strong>scape <strong>and</strong> Vegetation Characteristics<br />

The area is dissected broadly by snow fed tributary streams <strong>of</strong> the Jadh Ganga that drain the area to meet the Bhagirathi<br />

River at Bhaironghati. These tributaries are arranged in almost parallel lines where the mountain slopes are steep in<br />

the area <strong>of</strong> the central crystalline granites closer to Bhaironghati towards the southern portion <strong>of</strong> the Jadh Ganga valley<br />

but assume a dendritic pattern towards the north where slopes are comparatively gentler <strong>and</strong> the gradient <strong>of</strong> the Jadh<br />

Ganga is also less severe due to the plateau like formation proximal to Tibet. At some points on the Jadh Ganga more<br />

than one tributaries confluence to form an important drainage plexus, as at Tirpani, where the southerly flowing Jadh<br />

Ganga is met by the Rangmanch Gad from the west <strong>and</strong> the East Nala from the east. The lower portion <strong>of</strong> the valley is<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

extremely rugged <strong>and</strong> steep in the form <strong>of</strong> a canyon formed by the river Jadh Ganga. Visually, the study area is divisible<br />

into glacial <strong>and</strong> periglacial types <strong>of</strong> l<strong>and</strong>forms. The valley gradually widens as one goes for about 10 -15 kms from<br />

Bhaironghati. The areas close to MCT are highly broken <strong>and</strong> unstable owing to regular avalanches <strong>and</strong> enormous<br />

glacial erosion. On the right flank <strong>of</strong> Jad ganga between Gartang <strong>and</strong> Nilang there are deep gorges, visually impenetrable.<br />

One <strong>of</strong> such gorges leads to Sangla Valley in Himachal Pradesh, traditionally used by Gaddis for annual movement<br />

between Nilang Valley <strong>and</strong> their homel<strong>and</strong> with their domestic livestock. Nilang (3400 m asl) is the first traditional<br />

village that has been ab<strong>and</strong>oned subsequent to Chinese aggression. The mountain slopes around Nilang <strong>and</strong> beyond<br />

up to Tipani, Jadung <strong>and</strong> Neelapani Gad are extremely broken, at places with extensive scree slopes, colluvial<br />

deposits <strong>and</strong> lateral moraines. The morainic deposits are prone to wind erosion giving rise to typical barnacles<br />

at several places. The areas around Rangmanch Gad, Plumsumdo (PDA) <strong>and</strong> beyond are gentle <strong>and</strong> stable<br />

(Plates 2A, 2B).<br />

The lower parts <strong>of</strong> Jadh Ganga (Jahnavi) especially around Bhaironghati support Dry Temperate Deodar forests<br />

(Champion & Seth 1968) with open canopy <strong>and</strong> stunted growths. Pinus wallichiana occurs as a common associate.<br />

Second storey generally consists <strong>of</strong> Ribes alpestre, Rosa macrophylla, Abelia triflora, Viburnum cotinifolium, Jasminum<br />

humile, Berberis aristata, B. pseudumbellata, Artemisia japonica, etc. Broad-leaved species occurring in the shallow<br />

depressions are Populus ciliata, Acer acuminatum, Sorbaria tomentosa, Rubus niveus <strong>and</strong> Salix karelinii. Ground<br />

vegetation consists <strong>of</strong> Thalictrum foetidum, T. minus, Mirabilis himalaica, Veronica stewartii, Impatiens scabrida, I.<br />

brachycentra, Arenaria serpyllifolia, Arabidopsis himalaica, Arisaema flavum <strong>and</strong> Salvia nubicola. Between Karchha<br />

<strong>and</strong> Nilang the vegetation undergoes rapid transition from Deodar mixed blue pine to open juniper woodl<strong>and</strong> <strong>and</strong><br />

alpine scrub. Commonly associated tree species including Prunus cornuta <strong>and</strong> Euonymus fimbriatus, Artemisia<br />

dracunculus, A. santolinifolia, A. dubia, Abelia triflora, Viburnum cotinifolium, Juniperus communis, J. indica, Cotoneaster<br />

roseus, Berberis umbellata, B. pachyacantha <strong>and</strong> Lonicera hypoleuca are the common shrubs <strong>and</strong> the ground vegetation<br />

consists <strong>of</strong> Arenaria serpyllifolia, A. neelgherensis, Erigeron acer var. multicaulis, Asparagus filicinus <strong>and</strong> a few grasses<br />

such as Phaceleurus speciosus, Piptatherum munroi etc.<br />

Along the side stream courses near Karcha <strong>and</strong> on opposite slopes a few remnant patches <strong>of</strong> birch / Bhoj Patra (Betula<br />

utilis) can be seen. Ground vegetation <strong>of</strong> scattered birch patches consists <strong>of</strong> Anaphalis royleana, Astragalus maddenianus,<br />

Danthonia schneideri, Erigeron multiradiatus <strong>and</strong> Solidago virga-aurea. Beyond Nilang – on way to Naga, Nilapani <strong>and</strong><br />

Sonam the vegetation is rather sparse <strong>and</strong> in the form <strong>of</strong> scattered scrub. Characteristic species include Rhamnus<br />

prostrata, Ephedra gerardiana, Rosa webbiana, Spiraea canescens, Hyssopus <strong>of</strong>ficinale, <strong>and</strong> Astragalus c<strong>and</strong>olleanus.<br />

Stream courses <strong>and</strong> river banks are <strong>of</strong>ten dominated by Myricaria elegans <strong>and</strong> Salix flabellaris. The past camping sites<br />

<strong>and</strong> nitrogen rich areas are frequented by the high altitude nettle Urtica hyperborea, Chenopodium tibeticum, Rumex<br />

patentia <strong>and</strong> Atriplex hybrida.<br />

The interior valleys <strong>and</strong> undulating slopes exhibit characteristic steppe vegetation dominated by Lonicera spinosa <strong>and</strong><br />

Caragana versicolor <strong>and</strong> at places by Eurotia ceratoides. Here the unstable scree slopes harbour a distinct community<br />

characterized by Aconogonum tortuosum, Lamium rhomboideum, Cicer microphyllum <strong>and</strong> Rubia tibetica. Gregarious<br />

patches <strong>of</strong> Aconogonum tortuosum on scree slopes turn reddish pink during autumn making the hill slopes picturesque.<br />

The seemingly barren rock surfaces have luxuriant growth <strong>of</strong> colourful lichens e.g., Xanthoria elegans (orange red)<br />

<strong>and</strong> Acarospora chlorophoea (lemon yellow). The valley bottoms <strong>and</strong> moist places with clayey soil support patches <strong>of</strong><br />

sedge meadows dominated by Kobresia schoenoides, Kobresia royleana <strong>and</strong> various species <strong>of</strong> Carex. Towards<br />

Shankar glacier <strong>and</strong> Thag La (above 4500 m) the vegetation reflects the characteristic features <strong>of</strong> arctic tundra<br />

dominated by a few cushion forming dwarf herbs such as Thylacospermum caespitosum, Arenaria festucoides,<br />

Androsace globifera <strong>and</strong> Rhodiola tibetica. Thus the flora <strong>of</strong> the Nilang Valley typically reflects the prevalence <strong>of</strong> Trans-<br />

Himalayan elements.

Floral Wealth <strong>and</strong> <strong>Plants</strong> <strong>of</strong> High Conservation Significance<br />

Naithani (1988) gave the first botanical account <strong>of</strong> this Valley in which he reported about 170 species <strong>of</strong> flowering plants<br />

from this valley. The authors have been conducting regular floristic surveys in the valley since past 3-4 summers. Our<br />

latest estimate reveals that this valley harbours about 221 genera <strong>and</strong> 421 species <strong>of</strong> vascular plants distributed over 69<br />

families. A detailed break up <strong>of</strong> the general flora is given below :<br />

Groups Families Genera Species<br />

Pteridophytes 3 6 9<br />

Gymnosperms 4 4 7<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

A low rigid tufted shrub up to 60 cm tall. Branches slender, numerous <strong>and</strong> jointed. Joints covered with scales. Fruits<br />

ovoid 7-10 mm, with freshy red succulent bracts enclosing the 1-2 seeds. Frequent on alluvial fans, gravel terraces <strong>and</strong><br />

rocky slopes between 3000-5000 m asl. Young branches used for the extraction <strong>of</strong> ephedrine which is used for<br />

instantaneous cure <strong>of</strong> asthma, rheumatism <strong>and</strong> as heart stimulant. It is also used in preparation <strong>of</strong> nasal sprays to cure<br />

sinusitis <strong>and</strong> inflammation <strong>of</strong> mucous membrane.<br />

6. Dictamnus albus L. (Rutaceae)<br />

English Name : Burning Bush<br />

Strongly aromatic herb up to 50 cm. Stem <strong>and</strong> leaves clothed with gl<strong>and</strong>ular hairs. Leaves pinnate 20-30 cm long.<br />

Flowers 2.5-4 cm in erect racemes. Petals pink, easily falling. Sparse in inner dry ranges 2800 – 3300 m among<br />

bouldery scrub vegetation. Not in much local use but its potential as aromatic herb needs to be explored.<br />

7. Hyssopus <strong>of</strong>ficinalis L. (Lamiaceae)<br />

Local Name : Chhabra<br />

Perennial much branched <strong>and</strong> tufted herbs. Stem <strong>and</strong> leaves rough in texture, highly aromatic. Flowers bluish – purple.<br />

Frequent on inner dry ranges, especially on dry gravelly soil between 3400 – 4000 m asl. Leaves are used for extraction<br />

<strong>of</strong> certain oils by Ayurvedic industries. Tea <strong>of</strong> Hyssop flower tops are highly useful in the treatment <strong>of</strong> respiratory<br />

problems <strong>and</strong> for easing cough, sore throat <strong>and</strong> for loosening phlegm.<br />

8. Lillium polyphyllum Don. (Liliaceae)<br />

Local Name : Kakoli, Kashir Kakoli<br />

Perennial, erect herbs upto 50 cm tall. Leaves sessile, alternate or nearly opposite or whorled, narrowly lanceolate or<br />

linear, 8-12 x 1 – 2 cm. Bracts leaf-like, <strong>of</strong>ten whorled. Flower solitary or whorled with 4 – 10 long stalk. Perianth 5 – 8<br />

cm long, greenish white with purple dots inside, segments obtuse, recurved when fully exp<strong>and</strong>ed. Stigma obscurely 3lobed.<br />

Capsule 2.5 to 3.5cm long.<br />

Rather sparse in a few patches upto Karcha under open deodar forests. Tubers are said to be highly medicinal. One<br />

<strong>of</strong> the rare lilies <strong>of</strong> higher Himalaya.<br />

The Jadh Ganga valley has hosted large scale grazing for millennia <strong>and</strong> an estimated 30,000 sheep, goats <strong>and</strong> mules<br />

graze these pastures intensively even today, entering from Bhaironghati in May <strong>and</strong> branching out into various microcatchments<br />

to spend the summer. Lonicera <strong>and</strong> Caragana are heavily browsed during onward passage while Eurotia<br />

is favoured on the return journey with the onset <strong>of</strong> autumn. The plant diversity <strong>of</strong> Nilang is seriously threatened by heavy<br />

grazing even as the inclemency <strong>of</strong> the climate leaves a very short period for its revival. It is imperative that the Forest<br />

Department should involve the local communities <strong>and</strong> evolve a practical strategy <strong>of</strong> rotational grazing, allowing sufficient<br />

rest to grazed valleys to restore their diversity.

The northern flank <strong>of</strong> Himachal Pradesh (HP), separated by the Great Himalayan range <strong>and</strong> partly by the Pir Panjal (to<br />

the west), forms the southern extension <strong>of</strong> <strong>India</strong>n Cold Desert. A major portion <strong>of</strong> this l<strong>and</strong> mass has been categorized<br />

under the Biogeographic zone 1 i.e., <strong>India</strong>n Trans-Himalaya by Rodgers <strong>and</strong> Panwar (1988), <strong>and</strong> administratively this<br />

area falls under Lahaul & Spiti district <strong>of</strong> HP. Far from being barren wastel<strong>and</strong>, as has been erroneously referred in<br />

some texts, this region represents a unique ecosystem hosting an array <strong>of</strong> specialized plants <strong>and</strong> animals adapted to<br />

the harsh conditions prevailing here. This tract is among the sub-continent’s last remaining citadels <strong>of</strong> total wilderness.<br />

Along with the unique floral elements several birds <strong>and</strong> mammals exhibit seasonal migrations up <strong>and</strong> down the steep<br />

mountain slopes <strong>and</strong> depend on contiguous habitat for their movement. If any <strong>of</strong> the habitat layers are lost or degraded,<br />

numerous biological processes are disrupted. Therefore, conservation <strong>of</strong> this ecoregion is critical for the conservation<br />

<strong>of</strong> biodiversity not confined here but extending afar <strong>of</strong> its boundary limits.<br />

This article gives an overview <strong>of</strong> biophysical features, habitat <strong>and</strong> vegetation characteristics within cold deserts <strong>of</strong> HP.<br />

A few species <strong>of</strong> angiosperms, representing these habitats have been appended along with their uses, distribution <strong>and</strong><br />

threat status.<br />

Biophysical Features<br />

The cold deserts in the HP lie extending between 31° 44' 34'' N to 32° 59' 57'' N latitudes <strong>and</strong> 76° 46' 29'' E to 78° 41'<br />

34'' E longitudes, covering Lahaul & Spiti district <strong>and</strong> part <strong>of</strong> Pooh Sub-division in Kinnaur. The altitude ranges from<br />

2400 to 6400m above mean sea level <strong>and</strong> the area above 5600m remains perpetually under snow. The region exhibits<br />

typical alpine characteristics with low vegetation cover <strong>and</strong> primary productivity <strong>and</strong> stark seasonality. The region forms<br />

an integral part <strong>of</strong> the Himalayan ecosystem, with interconnected processes that extend from the riparian scrub along the<br />

river <strong>and</strong> stream courses to the high alpine meadows <strong>and</strong> boulder-strewn scree that spreads over the vast l<strong>and</strong>scape.<br />

However, to overcome these environmental stresses, both plants <strong>and</strong> animals have adapted themselves in many ways.<br />

Typical Trans-Himalayan faunal elements include the elusive snow leopard, brown bear, Tibetan wolf, majestic ibex <strong>and</strong><br />

blue sheep (Plate 3A).<br />

Despite harsh climatic conditions, the cold deserts have been occupied by human beings since the dawn <strong>of</strong> civilization.<br />

Secluded in selected pockets, the indigenous people have managed to eke out their living by adapting themselves to<br />

the harshness <strong>of</strong> their chosen habitat with tradition. The unpleasant face <strong>of</strong> development <strong>and</strong> the increasing biotic<br />

pressure in recent years along with the lack <strong>of</strong> appropriate technologies has led to the overuse <strong>and</strong> degradation <strong>of</strong> the<br />

natural resources <strong>of</strong> the region. The scarce vegetation cover is steadily getting degraded, <strong>and</strong> the limited water<br />

resources are getting depleted <strong>and</strong> polluted. Waste accumulation <strong>and</strong> poor sanitation <strong>and</strong> hygiene are new problems<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

<strong>of</strong> the region, <strong>and</strong> are leading to health problems among the local people. Firewood is scarce <strong>and</strong> power inadequate<br />

<strong>and</strong> unreliable for both domestic <strong>and</strong> occupational use. Very little research interest <strong>and</strong> technology development has<br />

been focused on these regions. Moreover few technologies that have been transferred have frequently not been<br />

aligned to the special needs <strong>and</strong> conditions <strong>of</strong> the region. Agriculture is done on terraced fields. One <strong>of</strong> the major<br />

features in the region is agro-forestry, under which local people have adopted willows <strong>and</strong> poplars which are planted<br />

along the margins <strong>of</strong> the agricultural fields. In the Patton sub-valley, however, fruit trees, such as walnut,<br />

plum, <strong>and</strong> peach, are also cultivated. Seabuckthorn (Hippophae spp.) is found in smaller patches on the interspaces<br />

<strong>of</strong> the terraces, particularly in those parts <strong>of</strong> the fields through which the irrigation channels pass (Rawat et al. 2006).<br />

Habitat <strong>and</strong> Vegetation Characteristics<br />

The evolutionary history <strong>of</strong> l<strong>and</strong>scape features <strong>and</strong> habitat characteristics in the cold deserts <strong>of</strong> Western Himalaya is<br />

beyond the scope <strong>of</strong> this article. However, current physical features <strong>and</strong> eco-climatic conditions reflect a mosaic <strong>of</strong><br />

numerous habitats <strong>and</strong> corridors for dispersal <strong>of</strong> the floral <strong>and</strong> faunal elements thereby resulting in high degree <strong>of</strong><br />

biodiversity. Though this particular region does not harbor a spectacularly rich flora like many other biomes <strong>of</strong> the world<br />

in terms <strong>of</strong> species diversity yet their morphological, ecological <strong>and</strong> behavioral adaptations are necessarily unique.<br />

The region has several focal species <strong>of</strong> immense conservation importance (Plates 3A & 3B). Some <strong>of</strong> the interesting<br />

features <strong>of</strong> natural habitats <strong>and</strong> corresponding vegetation have been described below:<br />

i. The Moist Meadows <strong>of</strong> Pir Panjal<br />

The areas along <strong>and</strong> immediately north <strong>of</strong> Pir Panjal range, especially towards Lahaul exhibits characteristic features<br />

<strong>of</strong> alpine moist meadows similar to Greater Himalaya. It forms a transition zone between the moist temperate <strong>and</strong><br />

alpine habitats. One <strong>of</strong> the most accessible <strong>and</strong> typical sites where this habitat can be seen is around Rohtang Pass<br />

that forms the beginning <strong>of</strong> Pir Panjal range. The meadows are dominated by species <strong>of</strong> Poa, Festuca <strong>and</strong> a large<br />

number <strong>of</strong> herbaceous species. A few species <strong>of</strong> high conservation significance in these habitats include Primula<br />

rosea, Meconopsis aculeata, Rheum australe, Lagotis spp., <strong>and</strong> Bistorta affinis. The lush green meadows around<br />

Rohtang slopes harbor the summer grazing grounds for herds <strong>of</strong> sheep, goats <strong>and</strong> mules. These grazing grounds over<br />

the years have become vulnerable to unpalatable native species in the company <strong>of</strong> some ever-increasing invasive<br />

elements, belonging mainly to the Polygonaceae <strong>and</strong> Brassicaceae family. The unpalatable plant species include<br />

Bistorta vaccinifolia, Primula denticulata, Meconopsis aculeata, Geranium wallichianum, Bistorta affinis, Geum elatum,<br />

Impatiens thomsonii, Salvia glutinosa, Senecio chrysanthemoides <strong>and</strong> Urtica hyperborea. Some other species like<br />

Anemone rivularis, Iris kemaonensis, Morina longifolia, Potentilla argyrophylla, Taraxacum <strong>of</strong>ficinale <strong>and</strong> Thermopsis<br />

barbata thrive under these stressed conditions <strong>and</strong> can be seen in gregarious formations.<br />

ii. Riverine scrub <strong>of</strong> Bhaga Valley<br />

The riverine scrub along Bhaga river is dominated by Hippophae rhamnoides, Salix alba, Myricaria elegans <strong>and</strong> Rosa<br />

webbiana. Regions where the adjoining glacial streams meet the river, glacial moraines <strong>and</strong> scree are covered with<br />

good Juniperus regeneration, e.g., the area opposite Jispa. At higher altitudes, the snow on the north facing slopes lasts<br />

longer into the summers. This results in the formation <strong>of</strong> special habitats which show a prominent effect on the<br />

composition <strong>of</strong> the flora. Betula utilis formation can be observed in moist gulleys among craggy cliffs <strong>and</strong> slopes, while<br />

the adjacent sun facing slopes have drier conditions favouring arid floristic elements like Juniperus spp. with undergrowth<br />

<strong>of</strong> Rosa webbiana, Ribes alpestre <strong>and</strong> Lonicera myrtillus. A good formation <strong>of</strong> Juniperus forest is found around Stingri<br />

near Keylong.


iii. Juniper woodl<strong>and</strong> <strong>and</strong> sub-alpine Scrub <strong>of</strong> Miyar Valley<br />

Miyar forms the North-Western part <strong>of</strong> Lahaul. This remote fascinating valley <strong>of</strong> Lahaul is hidden behind the l<strong>of</strong>ty<br />

Udaipur Range <strong>and</strong> remains snow bound for over half the year <strong>and</strong> is amongst the most inaccessible areas in the<br />

region. During the short summer months, however, the alpine passes, mountain slopes, meadows <strong>and</strong> moraines<br />

present a spectacular display <strong>of</strong> colours as the vegetation bursts into life. Quite a few patches <strong>of</strong> juniper tree (Juniperus<br />

semiglobosa Regel) can be seen here, which represents sub-alpine forests in the region. This is one <strong>of</strong> the featured<br />

species <strong>of</strong> high conservation <strong>and</strong> religious importance in the valley. In the moist valley area along Miyar rivulet, the cool<br />

temperate <strong>and</strong> sub-alpine zones are dominated by dry zone Cedrus deodara in association with gnarled trees <strong>of</strong><br />

Juniperus spp. Other prominent taxa in this zone are stunted associations <strong>of</strong> Juglans regia, Pyrus baccata, Prunus<br />

cornuta, Berberis spp., Rosa webbiana, Rosa eglanteria, Ribes grossularia, Cotoneaster bacillaris, Crataegus songarica,<br />

Populus balsamifera <strong>and</strong> Betula utilis. The mouth <strong>of</strong> the valley has a dominant presence <strong>of</strong> Datisca cannabina along<br />

the steep river valley <strong>and</strong> further into the valley the slopes are dotted with a dominance <strong>of</strong> beautiful flowered Eremurus<br />

himalaica (‘Praey’) during the onset <strong>of</strong> summer (Kapoor & Jishtu 2008).<br />

iv. Alpine Dry Scrub <strong>of</strong> Spiti<br />

Spiti valley, in general is characterized by sloppy mountain deserts with the growing season <strong>of</strong> 5 – 6 months (April to<br />

September). The annual snowfall varies from 150-200 cm with very negligible rainfall. The minimum average<br />

temperature during winters touches as low as -30 o C. Sub zero temperature prevails from December to February,<br />

whereas, around 0.5 0 C temperature is experienced during winter months. The air is very dry particularly in the summer<br />

months. Very high wind velocity in the afternoon <strong>and</strong> night hours results in heavy soil erosion <strong>and</strong> soil moisture losses.<br />

This area harbours typical alpine dry scrub dominated by Caragana versicolor, Lonicera spinosa, Rheum spp., <strong>and</strong><br />

Kraschenninikovia ceratoides. In riverine / moist areas gregarious patches <strong>of</strong> Hippophae tibetana can be seen, especially<br />

around Losar upstream <strong>of</strong> Kaza.<br />

v. Alpine Mixed Communities <strong>of</strong> Pin Valley<br />

Pin Valley, located to the south <strong>of</strong> Spiti river adjacent to Great Himalayan range, is peculiar in many ways. The<br />

vegetation exhibits characteristics <strong>of</strong> both the Greater <strong>and</strong> Trans-Himalaya. Common shrubs in the valley are Rosa<br />

webbiana, Hippophae rhamnoides subsp. turkistanica (‘Charma’) <strong>and</strong> Salix elegans (‘Changma’). The herbaceous<br />

vegetation turns to be pr<strong>of</strong>use during the summers <strong>and</strong> is predominantly constituted <strong>of</strong> grasses <strong>and</strong> sedges. Here, the<br />

flora is remarkably rich, prominent taxa being species <strong>of</strong> Aquilegia, Allium, Corydalis, Iris, Ranunculus, Potentilla,<br />

Pedicularis, Saxifraga, Sedum <strong>and</strong> Primula. Numerous plant species thrive in the area, among them many varieties <strong>of</strong><br />

Some Taxa <strong>of</strong> High Conservation Significance<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

First comprehensive documentation <strong>of</strong> the flora for Lahaul & Spiti was by Aswal <strong>and</strong> Mehrotra (1994) who reported 79<br />

families, 353 genera <strong>and</strong> 985 species <strong>of</strong> seed plants (Angiosperms <strong>and</strong> Gymnosperms) from the district. Many <strong>of</strong> the<br />

taxa listed in this work are rare <strong>and</strong> threatened. Others are extremely valuable for their medicinal properties, e.g., Allium<br />

carolinianum (‘Loadh’), Artemisia brevifolia (‘Nyurcha’), Ephedra gerardiana (‘Chhe’), Heracleum c<strong>and</strong>icans (‘Raswal’),<br />

Meconopsis aculeata (‘Charr-Bongcha’), Podophyllum hex<strong>and</strong>rum (‘Omo-Shey’), Physochlaina praealta (‘Lang Tang’)<br />

<strong>and</strong> Saussurea costus (‘Koonth’). Populations <strong>of</strong> many <strong>of</strong> these plants have suffered high depletion rates in the last<br />

decade or so. Species <strong>of</strong> Arnebia, Betula, Dactylorhiza, Juniperus <strong>and</strong> Podophyllum are on the threatened list <strong>of</strong> plants.<br />

What is also critical is that some <strong>of</strong> the plants are endemic to the region <strong>and</strong> extinction from the region would imply a<br />

loss in global biodiversity. Over harvesting for use <strong>and</strong> trade, destructive forms <strong>of</strong> harvesting, overgrazing, are some <strong>of</strong><br />

the causes leading to depletion <strong>and</strong> fragmentation <strong>of</strong> the species populations. Very little <strong>of</strong> the supply <strong>of</strong> plant material,<br />

which constantly falls short <strong>of</strong> the escalating dem<strong>and</strong>, is from regenerative sources, <strong>and</strong> much <strong>of</strong> the harvesting is<br />

through destructive collection methods. Collectors’ earnings are limited, much <strong>of</strong> the returns from the sale <strong>of</strong> the herbs<br />

going to middlemen <strong>and</strong> traders. This also makes them uncaring <strong>of</strong> the regeneration <strong>and</strong> long-term survival aspect <strong>of</strong><br />

the plants. Some <strong>of</strong> the taxa <strong>of</strong> high conservation significance in the region are given below:<br />

The taxon, according to IUCN red list categories is Data Deficient (DD), i.e. when there is inadequate information to<br />

make a direct or indirect assessment <strong>of</strong> its risk <strong>of</strong> extinction based on its distribution (IUCN 1993). Therefore these<br />

plant taxa may be well studied, <strong>and</strong> its biology may be well known, with appropriate data on abundance <strong>and</strong> distribution.<br />

Listing <strong>of</strong> taxa in this category indicates that more information is required <strong>and</strong> acknowledges the possibility that future<br />

research will show that a threatened classification is appropriate. Basic knowledge <strong>of</strong> these threatened habitats <strong>and</strong><br />

their floristic composition is <strong>of</strong> fundamental importance to biodiversity conservation (Arkadiusz & Sylwia 2006). It will be<br />

especially helpful in active management <strong>of</strong> rare plant communities, estimation <strong>of</strong> restoration possibilities <strong>and</strong> to assess<br />

their effective conservation. Floristic surveys are indispensable in analysing the environmental conditions <strong>of</strong> threatened<br />

habitats <strong>and</strong> the flora thriving there.<br />

Major Threats <strong>and</strong> Conservation Strategies<br />

Unique <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong><br />

i. NTFP Collection : Traditionally, people <strong>of</strong> the region are engaged in little mountain farming <strong>and</strong> animal husb<strong>and</strong>ry.<br />

Collecting medicinal plants from various mountain ecosystems is an important part <strong>of</strong> their traditional medicine<br />

system, but only trained medicine men or Amchis do this. However, some people are engaged in collection <strong>of</strong> medicinal<br />

plants for augmenting their income. Large-scale collection <strong>of</strong> the fodder <strong>and</strong> fuelwood from this ecoregion by the local<br />

people for storage <strong>and</strong> use during the prolonged cold winters is a substantial threat, especially because the floral<br />

25


Envis Bulletin<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

species in the region are very slow to regenerate. Some plants like Myricaria elegans, Colutea nepalensis, Rosa<br />

webbiana <strong>and</strong> species <strong>of</strong> Caragana are destructively harvested for fuel wood <strong>and</strong> other domestic uses by the local<br />

inhabitants. There is no exact figure to show how many <strong>and</strong> how much <strong>of</strong> the plants are collected from different habitats<br />

in the region. In recent years, due to increased domestic market dem<strong>and</strong>, over harvesting <strong>of</strong> wild plants is a common<br />

problem world-over resulting in the threat to some <strong>of</strong> these species.<br />

ii. Habitat Alteration : L<strong>and</strong> use change is seen as the main factor to cause the habitat loss for native flora in the<br />

region. The loss <strong>of</strong> habitat is being seen as one <strong>of</strong> the major causes <strong>of</strong> threats to biodiversity, <strong>and</strong> there are numerous<br />

threatened species <strong>of</strong> plants distributed in the region, e.g. Betula utilis, Juniperus spp., Arnebia euchroma, Allium spp.,<br />

Saussurea spp., etc. Like in other parts <strong>of</strong> the state the people in the cold deserts too are directly engaged in animal<br />

husb<strong>and</strong>ry, agriculture <strong>and</strong> horticulture. The cattle <strong>and</strong> sheep population is almost three times the humans, coupled<br />

with hordes <strong>of</strong> additional sheep <strong>and</strong> goats <strong>of</strong> the nomadic graziers coming to the alpine regions each summer.<br />

Moreover, the wild populations <strong>of</strong> wild sheep <strong>and</strong> goats have increased over the years due to complete ban on hunting.<br />

Protected areas that overlap the region are Pin Valley National Park, Rupi Bhabha Wildlife Sanctuary <strong>and</strong> Kibber<br />

Wildlife Sanctuary. Therefore, there seems to be a great pressure on the alpine pastures <strong>of</strong> the cold deserts. Indiscriminate<br />

use <strong>of</strong> the grazing areas has therefore resulted in critically low biomass availability along with the emergence <strong>of</strong> weeds<br />

that have threatened the native species. Pastures Meadow steppe <strong>and</strong> scrub ecosystems are the special habitats for<br />

some rare medicinal flora in the region. Due to overgrazing, vegetation degradation occurs in many areas <strong>of</strong> this region.<br />

Distinct plant assemblages can be identified in the moist alpine vegetation that is strongly aggregated by altitudinal<br />

variations suggesting the presence <strong>of</strong> distinct zones <strong>of</strong> the alpine flora. Elevation <strong>and</strong> specific locations are the dominant<br />

environmental gradients underlying the species composition in these specific habitats. Hence, the alpine pasture<br />

habitat in the cold deserts is not only a group <strong>of</strong> grasses but is an ecosystem in itself. Here, the survival <strong>of</strong> this habitat is<br />

directly related to the survival <strong>of</strong> native flora, fauna <strong>and</strong> the inhabitants <strong>of</strong> the region. All the three components therefore,<br />

interact with each other <strong>and</strong> maintain the dynamic equilibrium within an ecosystem. Some <strong>of</strong> the strategies for long<br />

term conservation <strong>of</strong> threatened taxa in the region include enhanced monitoring <strong>of</strong> the effects <strong>of</strong> exploitation for<br />

species, particularly for the species under trade.<br />

Conservation in such areas can not be achieved without the involvement <strong>of</strong> local communities, who are directly<br />

dependent on these resources for their livelihood. Their involvement in management would certainly help in conservation.<br />

These communities could be encouraged to set aside some habitats for in situ conservation <strong>of</strong> high value medicinal<br />

plants. Efforts are needed to establish cold desert conservatorium / medicinal plant gardens, MPCA’s in the region.<br />

There is a need to focus on the development <strong>of</strong> packages for cultivation <strong>of</strong> economically important medicinal plants<br />

with modern techniques including tissue culture <strong>and</strong> genetic engineering.<br />

While posted as Director, Pin Valley National Park, located in Spiti Sub-Division <strong>of</strong> Himachal Pradesh (HP) during<br />

1994, I frequently visited parts <strong>of</strong> Kibber WS. During one <strong>of</strong> such visits to Kibber, I came across an interesting,<br />

strongly aromatic plant on dry steep scree slopes near Komik village (4300m), which was identified by Dr. G.S.<br />

Rawat <strong>of</strong> WII Dehradun as Glechoma nivalis (Benth.) Press (Lamiaceae). This species had only a few individuals<br />

<strong>and</strong> it was restricted to loose scree slopes. Aswal & Mehrotra (1994) in the ‘Flora <strong>of</strong> Lahaul – Spiti’ have stated that<br />

there are no specimens <strong>of</strong> G. nivalis from HP in the <strong>India</strong>n Herbaria. Hence this note is being sent herewith along<br />

with a photograph (from Kibber WS) to authenticate the presence <strong>of</strong> G. nivalis in Spiti.

Kashmir Himalaya<br />

Kashmir, commonly called the Kashmir Valley, the ‘paradise on earth’, is situated in the Northwest Himalayan<br />

biogeographic zone in <strong>India</strong> between 33 0 .20' -34 0 .54' N latitudes <strong>and</strong> 73 0 .55' -75 0 .35' E longitudes, covering an area <strong>of</strong><br />

15,948 km 2 . Topographically, it is a deep elliptical bowl-shaped valley bounded by l<strong>of</strong>ty mountains <strong>of</strong> the Pir Panjal in<br />

the south <strong>and</strong> southwest <strong>and</strong> by the Great Himalayan range in the north <strong>and</strong> east, with 64% <strong>of</strong> the total area being<br />

mountainous. The Valley is asymmetrical, with 187 km diagonal length (from southeast to northwest corner), <strong>and</strong><br />

considerably varying breadth, being 115.6 km along the latitude <strong>of</strong> Srinagar (Kaul 1977). The altitude <strong>of</strong> the Valley basin<br />

at Srinagar is 1,600 m <strong>and</strong> rises to 5, 420 m at Kolahoi or “Gwashibror’, the highest peak among its surrounding<br />

mountains. Traversing the Valley is the river Jhelum <strong>and</strong> its tributaries, which feed many lakes for which Kashmir is<br />

famous. The Valley is divided into six administrative districts: Srinagar, Budgam, Pulwama, Anantnag, Baramulla <strong>and</strong><br />

Kupwara.<br />

Owing to great heterogeneity in its topography, altitude <strong>and</strong> climate, Kashmir harbours diverse habitats which support<br />

a rich floristic wealth that has been used as a resource-base by its people since times immemorial. No wonder, the<br />

region has been called a “biomass State” (Khoshoo 1997). Indeed Kashmir has ever been known for its economicallyvalued<br />

plants <strong>and</strong> their products, such as food, fodder, fibre, medicinal <strong>and</strong> aromatic plants, spices, perfumes,<br />

ornamentals, timber, small wood, <strong>and</strong> variety <strong>of</strong> other non-wood timber produce.<br />

The written records <strong>of</strong> floristic studies in Kashmir date back to 1822 when William Moorcr<strong>of</strong>t first collected plants from<br />

this Valley, followed by other western explorers, namely Victor Jacquemont, Royle, von Huegel <strong>and</strong> Vigne. Royle, for the<br />

first time published illustrations <strong>and</strong> taxonomic diagnoses <strong>of</strong> many plants from Kashmir. J. D. Hooker, in his Flora <strong>of</strong><br />

British <strong>India</strong> (1872-1897), cited plant material from this area with a large number <strong>of</strong> taxa. This was followed by<br />

important contributions to the flora <strong>of</strong> Kashmir by three botanists: Coventry (1923-1930), Blatter (1928-1929), <strong>and</strong><br />

Stewart (1972).<br />

The floristic studies in this region received a great boost with the establishment <strong>of</strong> the Jammu & Kashmir University at<br />

Srinagar in 1961. The same year, a Botanical Garden was laid down adjacent to the Department <strong>of</strong> Botany. Many a<br />

local students <strong>and</strong> teachers started research on various floristic aspects, including monographs, <strong>and</strong> with the plant<br />

material collected during the course <strong>of</strong> these studies was established a herbarium, the KASH, in 1972. The establishment<br />

<strong>of</strong> the Centre <strong>of</strong> Plant Taxonomy (COPT) in 1981, as an adjunct <strong>of</strong> the Department <strong>of</strong> Botany, was yet another milestone<br />

in the onward progress <strong>of</strong> floristic research in this area. This Centre has paved the way for publication <strong>of</strong> numerous<br />

research papers <strong>and</strong> some important books on the Kashmir Himalayan flora (e.g., Singh & Kachroo 1976, Dhar &<br />

Kachroo 1983, Munshi & Javeid 1986, Sharma & Jamwal 1988, 1998, Singh & Kachroo 1994, Navchoo & Kachroo<br />

1995, Dar et al., 2002, <strong>and</strong> Nasreen et al. 2003).<br />

The ancient flora <strong>of</strong> Kashmir is said to have been tropical, having changed to subtropical <strong>and</strong> temperate types during<br />

glacial phase <strong>of</strong> the Pleistocene era (Puri 1943, 1947; Vishnu-Mittre 1963). Thereafter, plants from various floristic<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

regions have entered the Valley through normal dispersal <strong>and</strong> anthropogenic interventions, rendering its present flora<br />

as Holarctic, <strong>and</strong> mostly a confluence <strong>of</strong> various floristic elements from many adjacent regions. A vivid vegetation<br />

pattern is seen along the gradient <strong>of</strong> altitudinal climatic belts. Beginning from somewhat subtropical formations, one<br />

finds in the temperate Valley domesticated plant systems <strong>and</strong> wetl<strong>and</strong> <strong>and</strong> aquatic formations, followed higher up in the<br />

mountains by forests, sub-alpine <strong>and</strong> alpine meadowl<strong>and</strong>s, alpine scrubs, etc.<br />

The wild-growing gymnosperms comprise not more than a dozen conifers, yet they dominate the forests. Dar & Naqshi<br />

(2002) <strong>and</strong> Dar et al. (2002) have reported 2,000 species <strong>of</strong> flowering plants from the Kashmir region; these are<br />

distributed over 710 genera in 132 families. Asteraceae, Poaceae, Brassicaceae, Rosaceae, <strong>and</strong> Lamiaceae are the<br />

first five larger families with regard to number <strong>of</strong> species; while Carex, Polygonum (sensu lato), Potentilla, Artemisia <strong>and</strong><br />

Nepeta are the larger genera. Presence <strong>of</strong> a large number <strong>of</strong> grasses <strong>and</strong> sedges is significant. In all, about 20%<br />

angiosperm species occur as weeds [Kaul (1986) recorded 401 species as weeds in 251 genera <strong>and</strong> 56 families];<br />

15% species comprise indigenous <strong>and</strong> exotic trees <strong>and</strong> shrubs [Ara et al. (1995) listed 295 arboreal species in 120<br />

genera <strong>and</strong> 60 families]; the aquatic <strong>and</strong> wetl<strong>and</strong> flora is also rich [Kak (1990) listed 196 species in 82 genera <strong>and</strong> 44<br />

families]; some 8% species are exclusively endemic to Kashmir (Dar et al. 2008), which is significant considering the<br />

fact that this region forms only 0.48 % l<strong>and</strong> mass <strong>of</strong> <strong>India</strong>.<br />

<strong>Special</strong> <strong>Habitats</strong><br />

For the purpose <strong>of</strong> habitat study, Kashmir may be divided into two broad ecological zones: the main valley zone, <strong>and</strong> the<br />

surrounding montane zone. Mostly under human habitation <strong>and</strong> cultivation, the main valley is beset with varied habitats;<br />

besides it possesses the following special habitats with interesting attendant vegetation types.<br />

1. Swamps <strong>and</strong> marshes<br />

Kashmir Valley is very rich in freshwater swamps <strong>and</strong> marshes. The swamps are water logged areas with water level<br />

above the soil surface. These support reed-swamp vegetation dominated by reeds (Phragmites australis), rushes<br />

(Juncus spp.), <strong>and</strong> sedges (Scirpus spp.); other tall plants, such as Butomus umbellatus <strong>and</strong> species <strong>of</strong> Typha, Equisetum,<br />

<strong>and</strong> Alisma, also occur occasionally. The marshes are like swamps but with the water level not rising above the surface.<br />

These support a luxuriant helophytic vegetation comprising rushes <strong>and</strong> sedges ( species <strong>of</strong> Scirpus, Carex, Cyperus<br />

<strong>and</strong> Fimbristylis), with occasional hygrophilous associates such as Lythrum salicaria, Galium palustre, Bidens tripartita,<br />

Prunella vulgaris, Triglochin palustre, Ranunculus sceleratus, Spiranthes sinensis <strong>and</strong> Persicaria hydropiper.<br />

2. Floating gardens<br />

Kashmir Valley abounds in lakes, which are home to a varied hydrophytic vegetation, both benthon <strong>and</strong> pleuston. Within<br />

<strong>and</strong> along the lakes occur stabilized isl<strong>and</strong>s that have been formed ingeniously by local boat men -‘Hanjis’ using willow<br />

trees ( Salix spp.) as tent poles along margins <strong>and</strong> being used for growing a rich variety <strong>of</strong> local vegetables. Some<br />

common weeds associated with these isl<strong>and</strong> farms are Bidens cernua, Persicaria hydropiper, Mentha arvensis, Rorippa<br />

sylvestris, Sium latijigum, Lythrum salicaria, Galium palustre, Myosotis palustris, Veronica anagallis-aquatica, Plantago<br />

major <strong>and</strong> Cyperus difformis.<br />

3. Graveyard sites<br />

Every village/habitation site in Kashmir has a graveyard, which is rich in nutrients. The graveyards are frequently planted<br />

with a few trees <strong>of</strong> Celtis australis <strong>and</strong> Morus alba <strong>and</strong> harbor a distinct vegetation. It is customary to grow some bulbous<br />

geophytes, such as species <strong>of</strong> Sternbergia, Narcissus <strong>and</strong> Iris on <strong>and</strong> around fresh graves. After some time these get


naturalized <strong>and</strong> grow pr<strong>of</strong>usely on such sites. Sternbergia fischeriana <strong>and</strong> Narcissus tazetta are the first to bloom in<br />

February-March, while species <strong>of</strong> Iris, such as I. germanica, I. kashmiriana <strong>and</strong> I. ensata bloom in April-May, rendering<br />

a colorful look to these sites.<br />

4. Mud wall <strong>and</strong> masonry wall sites<br />

The mud walls are raised to cover the kitchen gardens, orchards <strong>and</strong> lawns. They form a characteristic habitat for<br />

vegetation which shows more or less a seasonal rhythm. During spring, under moderate temperature <strong>and</strong> high moisture<br />

content <strong>of</strong> the substratum, a luxuriant growth <strong>of</strong> plants, such as Veronica persica, V. biloba, Poa annua, Cardamine<br />

hirsuta <strong>and</strong> Stellaria media is seen. The summer, exhibiting an increase in temperature with a corresponding decrease<br />

in moisture content <strong>of</strong> the substratum, shows a decline in the number <strong>of</strong> plant species <strong>and</strong> the main taxa colonizing<br />

mud walls during this season include Anthemis cotula, Galinsoga parviflora, Sisymbrium loesellii, <strong>and</strong> Eragrostis<br />

minor. During autumn the substratum becomes almost dry <strong>and</strong> only some hardy species, such as Artemisia<br />

tournefortiana, Ipomoea eriocarpa <strong>and</strong> Urtica dioica are able to bloom. Dar & Kachroo (1983) recorded 68 species <strong>of</strong><br />

flowering plants, belonging to 27 families, growing on the mud walls <strong>of</strong> G<strong>and</strong>erbal in Srinagar, all <strong>of</strong> which are<br />

herbaceous with 75% being annual, revealing predominance <strong>of</strong> therophytic life forms on these walls.<br />

Masonry walls are frequently raised as bounds along water courses. They support species such as Oxalis corniculta,<br />

Arenaria serpyllifolia, Stellaria media, Campanula pallida, Plantago lanceolata, Capsella bursa-pastoris, Veronica<br />

persica <strong>and</strong> Epilobium spp., together with many composites (Taraxacum spp., Gnaphalium affine <strong>and</strong> Lactuca dissecta)<br />

<strong>and</strong> grasses (Poa annua, P. bulbosa <strong>and</strong> Calamagrostis pseudophragmites).<br />

5. Rocky gorges<br />

These are narrow passages <strong>of</strong> rocks, rocky slopes <strong>and</strong> rocky banks through which flow the nallahs <strong>and</strong> streams in the<br />

montane terrain. The vegetation along these sites is mainly lithophytic, including characteristic scrubs <strong>of</strong> Isodon<br />

rugosus, Viburnum foetens <strong>and</strong> Clemaris spp., together with herbaceous elements such as Arisaema jacquemontii,<br />

Campanula cashmeriana, Cirsium falconeri, Gentiana cachemirica, Leonurus cardiaca, Minuartia kashmirica, Oxyria<br />

digyna, Rumex hastatus, Dictamnus albus, Stachys sericea, <strong>and</strong> species <strong>of</strong> Corydalis, Epilobium, Nepeta, Sedum,<br />

Thalictrum, <strong>and</strong> Swertia.<br />

6. Moist alpine meadows<br />

Kashmir is known for its beautiful alpine valleys, locally known as ‘margs / bahaks’. These are used as summer<br />

pastures by graziers <strong>and</strong> harbor open grassl<strong>and</strong> communities, comprising colorful species <strong>of</strong> Aconitum, Aquilegia,<br />

Delphinium, Callianthemum, Aster, Inula, Salvia, Phlomis, Campanula, Geranium, Barbarea, Potentilla, Geum,<br />

Chaerophyllum, Selinum <strong>and</strong> Fritillaria.<br />

Certain stretches within alpine meadows have mostly a frozen <strong>and</strong> poorly-drained soil surface, resulting in damper or<br />

marshy depression-like situations. This moor-like habitat is covered by mossy mats <strong>and</strong> its vegetation is dominated by<br />

hygrophytic sedges such as Juncus sphaceluros, Luzula spicata, Kobresia nitens, Carex spp., <strong>and</strong> grasses such as<br />

Poa alpina, P. versicolor, Phleum alpinum, Alopecurus himalaicus, etc. A few ground-hugging herb-like shrubs (Salix<br />

flabellaris <strong>and</strong> Gaultheria trichophylla) with the hygrophilous herbaceous species <strong>of</strong> Pedicularis, Primula, Anemone,<br />

Aconitum, Ranunculus, Epilobium, Gentiana, Jaeschkea, Lomatogonium, <strong>and</strong> Swertia are also common here.<br />

7. Alpine rocky <strong>and</strong> scree slopes<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong><br />

Kashmir Himalaya<br />

These comprise bare rock <strong>and</strong> scree with interstitial gravel above the alpine scrubs. This special habitat shows a rich<br />

growth <strong>of</strong> epilythic lichens <strong>and</strong> numerous xerophilous plants. Dwarf patches <strong>of</strong> Ephedra gerardiana <strong>and</strong> Cassiope<br />

31


Envis Bulletin<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

fastigiata manage to grow on these slopes, together with a number <strong>of</strong> hardy rosette <strong>and</strong> other lithophytes, such as<br />

Corydalis crassissima, Papaver nudicaule, Paraquilegia anemonoides, Anemone rupicola, Potentilla curviseta, Arnebia<br />

benthamii, Minuartia foliosa, Sedum crassipes, Bistorta vivipara, Dolomiaea baltalensis, Jurinea ceratocarpa, Lactuca<br />

laevigata, Waldheimia tomentosa, Arabis spp., Chorispora sabulosa, Draba spp., Ermania kashmiriana, Saussurea<br />

gossypiphora <strong>and</strong> S. sacra.<br />

8. Glacial moraines<br />

Glaciers usually occur in gulleys, criques <strong>and</strong> coles along high alpine mountains in Kashmir, though at some places<br />

they descend to elevations <strong>of</strong> 3,300m. They comprise huge masses <strong>of</strong> ice <strong>and</strong> provide inimical conditions for vascularplant<br />

growth. However, the fringes <strong>of</strong> glaciers melt during summer, providing melt water to the substratum throughout<br />

the growing season. This moist habitat along melting glaciers supports distinctive vegetation represented by species<br />

such as Adonis chrysocyathus, Trollius acaulis, Oxygraphis polypetala, Aquilegia nivalis, Anemome polyanthes,<br />

Ranunculus munroanus, Thlaspi cochlearioides, Bergenia stracheyi, Saxifraga sibirica, Pedicularis spp., Swertia<br />

petiolata, Aster diplostephioides, Lloydia serotina, Milium effusum, <strong>and</strong> Juncus leucomelas. Occasionally, species <strong>of</strong><br />

Rhododendron are also seen growing along glaciers.<br />

<strong>Threatened</strong> <strong>Plants</strong><br />

A century ago, Kashmir would have been a naturalist’s paradise. Dense forests in Kashmir descended up to the interior<br />

<strong>of</strong> present-day city <strong>and</strong> towns, the wood was easily <strong>and</strong> abundantly available from these forests <strong>and</strong> formed the main<br />

item <strong>of</strong> the timber <strong>and</strong> fuel, <strong>and</strong> that the preponderant medicinal plants were the main source <strong>of</strong> the local Hakim<br />

(Unani) system <strong>of</strong> medicine. Over the decades, however, a large number <strong>of</strong> species have been rendered threatened<br />

due to various anthropogenic causes, such as habitat loss or modification (particularly deforestation <strong>and</strong> exp<strong>and</strong>ing<br />

urbanization), over-exploitation <strong>of</strong> economically important plants, alien species invasion, unchecked grazing, unplanned<br />

development, <strong>and</strong> great tourist influx. Dar & Naqshi (2002) have reported 356 plant taxa (346 species + 3 subspecies<br />

+ 7 varieties) as threatened in Kashmir <strong>and</strong> Ladakh phytogeographical region. Some critically endangered plants <strong>of</strong><br />

Kashmir (Plate 4) are given as follows:<br />

5.0 <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> Jammu Region, North-West<br />

Himalaya <strong>and</strong> Strategies for Their Conservation<br />

Introduction<br />

O.P. Sharma<br />

State Forest Research Institute<br />

Jammu, Jammu & Kashmir<br />

Jammu region in the North-West Himalaya is characterized by a rapid transition from sub-tropical to alpine ecoclimatic<br />

conditions as one moves from south (Kathua) to north (Kishtwar). The region harbours a rich array <strong>of</strong> flora <strong>and</strong><br />

fauna manifested by diverse habitat conditions. However, the region is subjected to enormous anthropogenic pressures<br />

such as over exploitation <strong>of</strong> timber as well as non-timber forest products especially wild medicinal plants, livestock<br />

grazing, ill planned developmental activities <strong>and</strong> deforestation. As a result, natural forests <strong>and</strong> grassl<strong>and</strong>s have degraded<br />

<strong>and</strong> top soil has eroded from most <strong>of</strong> the mountain slopes. The soil erosion is particularly severe in the Shiwaliks.<br />

The floristics <strong>and</strong> distribution <strong>of</strong> rare <strong>and</strong> threatened plants <strong>of</strong> Jammu region has been worked out by several authors<br />

e.g., Sharma & Kachroo (1981), Singh & Kachroo (1983, 1994), Swami & Gupta (1998), Singh et al. (2002), Choudhary<br />

& Rao (2002), Kapoor et al. (1964) to name a few. The forest types recorded in the state range from thorn scrub to<br />

temperate <strong>and</strong> alpine types (Champion & Seth 1968). However, there have been marked <strong>and</strong> perceptible changes in<br />

flora as well as vegetation <strong>of</strong> the region since the publication <strong>of</strong> above works. Distribution <strong>and</strong> abundance <strong>of</strong> many<br />

species has drastically reduced. For example, shady moist ravines <strong>and</strong> semi-evergreen forests along the foot-hills are<br />

extremely rare now. In such habitats species such as Myrica esculenta (Myricaceae), Bisch<strong>of</strong>ia javanica, vern Chiuntar,<br />

Cheentar or Paniala (Euphorbiaceae), <strong>and</strong> Cinnamomum tamala (Lauraceae) used to grow pr<strong>of</strong>usely 2 – 3 decades<br />

ago but these trees have become extremely rare. Presently, Myrica esculenta can be seen growing only at two localities,<br />

one in Kardoh Nala (Basohli-Bani) <strong>and</strong> second in Saamna banj (Ram Nagar Forest Division). Buxus wallichiana<br />

(Buxaceae), an evergreen tree <strong>of</strong> temperate forests seen growing at Pancheri-La<strong>and</strong>er (Udhampur Forest Division),<br />

Saamna banj (Ram Nagar Forest Division), Budhal <strong>and</strong> Thannam<strong>and</strong>i (Rajouri Forest Division). It prefers well drained<br />

soil having pH range from 5.5 to 7.4. Its crocodilian fissured bark looks elegant. Fruit set is low <strong>and</strong> as a result<br />

regeneration is poor. It is called Chikhri in Dogri <strong>and</strong> Pahari languages <strong>and</strong> is in great dem<strong>and</strong> by the h<strong>and</strong>icraft artisans<br />

who use it for making variety <strong>of</strong> articles like snuff boxes, combs, forks, spoons, toys & decoration pieces. The wood<br />

sustains a whole cottage industry in Rajouri – Poonch area <strong>of</strong> Jammu. On account <strong>of</strong> its overexploitation, its populations<br />

are dwindling day by day. Other taxa <strong>of</strong> high conservation significance in the region include Holmskioldia sanguinea<br />

(Verbenaceae), Pittosporum eriocarpum (Pittosporaceae), Taxus wallichiana (Taxaxeae), Litsea glutinosa (Lauraceae),<br />

Corylus jacquemontii (Corylaceae).<br />

In this article, a few rare <strong>and</strong> threatened species (Plate 5) <strong>of</strong> Jammu region have been appended along with their<br />

dwindling status <strong>and</strong> strategies for long term conservation.<br />

1. Eremurus himalaicus Baker (Liliaceae) : Wild ornamental <strong>and</strong> edible herb <strong>of</strong> dry temperate region. Recorded<br />

from Padder area <strong>of</strong> Kishtwar where it has declined drastically during last two decades. Locally known as Kaihloon,<br />

Dharshaag, Chhil haak, Bulkutor Yalun. It is overexploited for its edible leaves <strong>and</strong> roots. It also grazed by the cattle<br />

<strong>and</strong> seed formation is hampered in the natural habitat. Edible young leaves are also sold in the Kishtwar market<br />

during March-April. This herb grows under the canopy <strong>of</strong> Pinus gerardiana in the open blanks. Soil in its natural<br />

habitat is usually prone to avalanches during winter <strong>and</strong> early spring.<br />

2. Eremostachys superba Royle ex Benth. (Lamiaceae) : Wild ornamental herb <strong>of</strong> sub-tropical areas viz. N<strong>and</strong>ni<br />

Wildlife Sanctuary, Sunderbani, Channi Paraat area <strong>of</strong> Rajouri <strong>and</strong> Pauni Bharkh area <strong>of</strong> Reasi Forest Division.<br />

The last area is under stress due to overexploitation by nomadic Gujjars who feed its tuberous roots to the milch<br />

cattle for enhancing milk yield. Digging <strong>of</strong> roots <strong>and</strong> plucking <strong>of</strong> h<strong>and</strong>some golden yellow spikes leaves this herb<br />

without adequate seed formation. As the plant is pollinated by insects, non-availability <strong>of</strong> pollinators in sufficient<br />

number is likely to be a major factor causing its depletion in the wild. Dr. Susheel Verma, Scientist, Centre for<br />

Biodiversity Studies, Baba Ghulam Shah Badshah University, Rajouri has carried out detailed study on its floral<br />

biology <strong>and</strong> ex situ conservation. Habitat <strong>of</strong> this magnificent herb is under anthropogenic pressure due to soil<br />

erosion, soil compaction <strong>and</strong> loss <strong>of</strong> moisture in the ground soil <strong>of</strong> forests in the Shiwaliks.<br />

3. Gentiana kurroo Royle (Gentianaceae) : A very h<strong>and</strong>some gentian <strong>of</strong> temperate Chir pine <strong>and</strong> oak forests<br />

which flowers during September-October. It is declining at an alarming rate in the state. Once, abundant around<br />

Termain, Kalounta (Ram Nagar Forest Division), Pancheri, Maungri Basnot (Udhampur Forest Division), Banjal,<br />

Jouriyan Mata, Baikan, Lohai Malhar (Billawar Forest Division), this herb has sufferred due to habitat loss, dam<br />

building, over-exploitation, forest fires <strong>and</strong> illegal trade under the name Karu booti. It is also called as Ram Vaan<br />

because <strong>of</strong> its effective healing properties. It is mixed <strong>and</strong> traded with true Karu or Kaur, Picrorrhiza kurrooa which<br />

st<strong>and</strong>s almost wiped out in the sub-alpine meadows in the Jammu region <strong>and</strong> is seen only in areas like Marwah<br />

Dachhan in Kishtwar <strong>and</strong> Seoj Dhar in Ram Nagar.<br />

4. Arnebia benthamii (Wall. ex G. Don) Johns. (Boraginaceae) : A rare species <strong>of</strong> higher altitudes especially in<br />

dry temperate slopes e.g., Marwah-Dachhan <strong>and</strong> Kishtwar mountains. It is locally dwindling due to overexploitation<br />

for its medicinal roots under the name ‘Ratanjot’ or ‘Rattmundi’. Flowering spikes are useful for cardiac ailments.<br />

It’s allied species, A. euchroma is reported from Trikuta hills, around Hathi Matha <strong>and</strong> Bhairoo Ghati in the Reasi<br />

Forest Division.<br />

5. Meconopsis aculeata Royle (Papaveraceae) : Also known as ‘Queen <strong>of</strong> Himalayan Flowers’, this Himalayan<br />

Blue Poppy can be seen growing naturally in the Simthan pass, Margan Top, Wadwan <strong>and</strong> Marwah area <strong>of</strong><br />

Kishtwar in the Jammu region. It usually prefers dry temperate stony habitats near mountain streams <strong>and</strong> forest<br />

edges. It is locally called Gul-Neelmi because <strong>of</strong> its sky blue flowers. Degradation <strong>of</strong> soil due to over grazing,<br />

deforestation in the fir-spruce forest areas, multiple dam building over the river Chenab <strong>and</strong> large scale deforestation<br />

in the upper mountains are the major causes <strong>of</strong> its decline. It grows sporadically <strong>and</strong> shows poor seeding. It needs<br />

to be put under cultivation in the hill stations as wild ornamental plant.<br />

6. Habenaria intermedia D. Don (Orchidaceae) : A h<strong>and</strong>some orchid found in temperate forest fringes <strong>and</strong> grassy<br />

meadows. Tuberous roots are harvested for medicine. It is very sensitive to changes in habitat <strong>and</strong> restricted to a<br />

few localities like Marta (Ram Nagar), Chew (Billawar) <strong>and</strong> Moungri Basnot (Udhampur). Despite repeated search<br />

the author could not relocate its populations in the areas where it used to occur in the past.<br />

7. Balanophora involucrata Hook. f. (Balanaphoraceae) : A saprophytic angiosperm, usually seen growing under<br />

bushes <strong>of</strong> Viburnum gr<strong>and</strong>iflorum (Vern. Guchh, Teldi) <strong>and</strong> Rhododendron campanulatum (Vern. Sarangar) in the<br />

temperate forests <strong>of</strong> Rajouri-Poonch where it is collected by Gujjars <strong>and</strong> used as tea substitute. Soil erosion, loss<br />

<strong>of</strong> habitat due to l<strong>and</strong>slides <strong>and</strong> deforestation are the main threats. It is called ‘Mastaani Booti’ by the local people<br />

in Kashmir.<br />

8. Ceropegia bulbosa Roxb. (Asclepiadaceae) : Slender climber <strong>of</strong> sub-tropical deciduous forests <strong>of</strong> Rajouri <strong>and</strong><br />

Udhampur Forest Divisions. Because <strong>of</strong> deforestation <strong>of</strong> Khair trees, its habitat has been disturbed in recent<br />

decades. Widespread invasion <strong>of</strong> weeds such as Parthenium hysterophorus has also suppressed its growth in the

wild. Tubers are eaten by locals. It used to be abundant in Khadakpanjaah area <strong>of</strong> Kalakote <strong>and</strong> Tikri in Udhampur<br />

but is quite rare these days.<br />

9. Atropa acuminata Royle ex Lindley (Solanaceae) : Deadly poisonous mountain perennial found growing in<br />

wild especially around Loran, Bufliaz <strong>of</strong> Poonchh Forest Division <strong>and</strong> Gool-sangaldaan area <strong>of</strong> Ramban Forest<br />

Division. It also grows along the fringes <strong>of</strong> Kail, Fir <strong>and</strong> oak forests. It is called Bisraal, Bra<strong>and</strong> <strong>and</strong> Tookan Sool by<br />

the locals.<br />

10. Notholirion thomsonianum (Royle) Stapf. (Liliaceae) : Fragrant flowering bulbous herb which grows in rocky<br />

places along the Ban-Ganga. It is quite an attractive plant <strong>of</strong> Jammu region but quite rare in the area. Author<br />

collected this herb for the first time during March, 2008 from a hillock along the side <strong>of</strong> Ban-Ganga at Katra. This<br />

species is recommended for cultivation in the gardens.<br />

For the conservation <strong>of</strong> above mentioned species <strong>and</strong> also for all other threatened taxa <strong>of</strong> the region both in situ <strong>and</strong> ex<br />

situ measures would be essential. Forest Department needs to raise the nurseries <strong>of</strong> high value medicinal <strong>and</strong><br />

aromatic trees <strong>and</strong> execute population recovery programmes in various reserved forests. Volunteers <strong>and</strong> non-government<br />

organizations can also be motivated to grow such species along the fringes <strong>of</strong> forests <strong>and</strong> cultivated fields. The Centre<br />

for Biodiversity Studies, Baba Ghulam Shah Budshah University Rajouri has taken an initiative <strong>of</strong> raising the seedlings<br />

<strong>of</strong> Buxus wallichiana in the nurseries for its rehabilitation in the Pir Panjal Biodiversity Park <strong>of</strong> Rajouri. Such efforts need<br />

to be upscaled <strong>and</strong> replicated in other parts <strong>of</strong> the state. The Horticulture Department can take up a few species for ex<br />

situ conservation <strong>and</strong> genetic improvement. For example, the hedgel nut (Corylus jacquemontii), locally called Thaangi,<br />

Urmuni in Pahadi <strong>and</strong> Pogli dialects, is sold in the local market but it has poor regeneration in the forests. It needs to be<br />

grown as a horticultural crop. Superior grafting with Turkish varieties is desirable for enhancing yield <strong>of</strong> its nuts.<br />

Likewise, State Forest Department can include several woody <strong>and</strong> herbaceous species for afforestation <strong>and</strong> reforestation<br />

programmes under Clean Development Mechanism to serve the dual purpose <strong>of</strong> biodiversity conservation <strong>and</strong> carbon<br />

sequestration.<br />

6.0 Rare <strong>and</strong> Little Known <strong>Plants</strong> from<br />

Lower Himachal Pradesh<br />

Krishan Lal<br />

Himachal Pradesh PWD, Sangrah, Sirmaur - 173 023<br />

kishan.1956@rediffmail.com<br />

The Shivaliks <strong>and</strong> outer Himalayan ranges in Himachal Pradesh have received relatively less attention <strong>of</strong> plant explorers<br />

<strong>and</strong> phytogeographers. Some <strong>of</strong> the important contributors on the flora <strong>of</strong> this region include Collett (1921), Chowdhery<br />

& Wadhwa (1984) <strong>and</strong> Kaur & Sharma (2004). However, there have been rapid changes in habitat conditions in this<br />

region due to heavy anthropogenic pressures. The author has been making observations on the flora <strong>of</strong> the lower<br />

Himachal especially the Sirmaur district for the past ten years. In this article, a few rare <strong>and</strong> little known species from the<br />

lower parts <strong>of</strong> Himachal Pradesh have been appended along with their colour photos (Plate 6). Most <strong>of</strong> these species<br />

have very small <strong>and</strong> fragmented populations <strong>and</strong> they need to be given high priority for in situ conservation <strong>and</strong> regular<br />

monitoring.<br />

1. Hibiscus trionum Linn. (Malvaceae) : So far recorded only 3-5 individuals near cultivated fields at Mangrah,<br />

Sarahan (1300m).<br />

2. Rauvolfia serpentina Benth. ex Kurz. (Apocynaceae) : It had been reported only from Simbalwara<br />

Wildlife Sanctuary in the past but despite repeated search it has not been located since the past 10 years. It is feared<br />

that this species has gone locally extinct from the above sanctuary.<br />

3. Sphaeranthus indicus DC. (Asteraceae) : Once frequent in paddy fields around Poanta Sahib, Barma<br />

Papri (Nahan). Now species is rarely seen perhaps due to excessive use <strong>of</strong> chemical fertilizers <strong>and</strong> intensive<br />

farming.<br />

4. Uraria picta Desv. ex DC. (Papilionaceae) : Rare, reported from Himachal Pradesh but it seems to have<br />

gone locally extinct from most <strong>of</strong> the localities due to changes in habitat conditions <strong>and</strong> over exploitation.<br />

5. Onosma thomsonii Clark (Boraginaceae) : Extremely rare. Only 3-4 individuals seen at Devadhar near<br />

Sangrah (1500 m), on limestone rocks. There has been heavy quarrying <strong>of</strong> lime stone from the quoted locality <strong>and</strong><br />

the species is on the verge <strong>of</strong> extinction. This species was reported for the first time recently (Lal & Rawat 2008).<br />

Previously known only from west <strong>of</strong> Kishenganga valley in Kashmir including Banihal Pass, Swat, Hazara <strong>and</strong><br />

Kagan between 1000 – 2000 m asl.<br />

6. Tricholepis roylei Hook. (Asteraceae) : An erect under-shrub up to 1.5 m high. Branches, petioles <strong>and</strong><br />

leaves densely clothed with white tomentum. Leaves elliptic, 8 x 3 cm, toothed. Heads solitary, terminal, up to 5 cm<br />

in diameter, pink. Flowering <strong>and</strong> Fruiting: August – September. Sparse, 15 – 20 individuals were seen on way to<br />

Renuka between Shiv Temple to Raicha (1200-1400 m asl), especially dry rocky slopes (Lal & Rawat 2008).<br />

7. Nervillia gammieana Hook.f. (Orchidaceae) : Rather sparse, on moist forest floors <strong>of</strong> Sal (Shorea robusta),<br />

seen at Shambhuwala, Nahan 700m.<br />

8. Eulophia dabia D.Don (Orchidaceae) : Extremely rare. Recently located near Una (600 m) on the bank <strong>of</strong><br />

seasonal stream in association with Imperata cylindrica <strong>and</strong> Saachrum benghalense.<br />

7.0 Some <strong>Plants</strong> <strong>of</strong> Taxonomic <strong>and</strong> High Conservation<br />

Significance in Uttarakh<strong>and</strong> Himalaya<br />

Introduction<br />

Manoj Ch<strong>and</strong>ran<br />

Almora Forest Division, Almora<br />

ch<strong>and</strong>ranmanoj@hotmail.com<br />

Uttarakh<strong>and</strong> Himalaya has received attention <strong>of</strong> a large number <strong>of</strong> botanists yet it remains rather under explored. The<br />

state lies in the watersheds <strong>of</strong> Yamuna, Ganga, Ramganga <strong>and</strong> Kali (Sharda) rivers <strong>and</strong> its tributaries. It has four broad<br />

eco-climatic zones, viz., the Terai-Bhabar <strong>and</strong> Shiwaliks, the middle Himalaya, the Greater Himalayas <strong>and</strong> the Trans-<br />

Himalaya. The wide variation in altitude <strong>and</strong> climate makes it ideal for sustaining a rich diversity <strong>of</strong> plant <strong>and</strong> animal<br />

species. The major vegetation types includes Tropical Moist Deciduous Forests, Subtropical Pine Forests, Subtropical<br />

Broad Leaved Forests, Temperate Conifer <strong>and</strong> Broad Leaved Forests, Alpine meadows <strong>and</strong> Alpine scrub as one goes<br />

from the lower to higher altitudes in the state. Some <strong>of</strong> the botanical hotspots in the state are Corbett National Park,<br />

Patwadangar, Lower Gori valley, Kalamuni ridge, M<strong>and</strong>al, Deoban, Binsar, Thalkedar, Yamunotri, Valley <strong>of</strong> Flowers,<br />

N<strong>and</strong>a Devi <strong>and</strong> Ralam Valley. Even though the region has been extensively surveyed by the botanists in the past,<br />

several localities remain under-explored. Some <strong>of</strong> the groups need taxonomic revision <strong>and</strong> others need status surveys.<br />

It is interesting to note that some <strong>of</strong> the species reported as common are very rare. For example, Cupressus torulosa,<br />

the Himalayan Cypress is supposed to be a common coniferous tree in the Western Himalaya (Osmaston 1927), but<br />

the reality is different. There are only few isolated populations at Naina Peak in Nainital on the ascent to Kalamuni in<br />

Pithoragarh, Chakarata <strong>and</strong> small scattered trees elsewhere. All these populations are in the altitudinal range <strong>of</strong> 2000-<br />

2500 m above msl. The common species mistaken as Cupressus torulosa in Mussorie, Naintal <strong>and</strong> many other<br />

plantations are actually a mixture <strong>of</strong> different species <strong>of</strong> exotic Cupressus, Juniperus <strong>and</strong> other similar genera. One <strong>of</strong><br />

the plantations near Nainital proved to be a mixture <strong>of</strong> 12 species <strong>of</strong> exotic Cupressus. This mixture is a result <strong>of</strong><br />

collection <strong>of</strong> seeds from the exotic Cupressus collection in the FRI campus at Dehradun by the local seed suppliers in<br />

the past, resulting in mixed mother plantations from where further seed collection was done. The Forest Department<br />

has started measures to identify true populations as seed plots <strong>and</strong> supply certified seeds so that only the real Cupressus<br />

torulosa is introduced in future planations.<br />

This article deals with ten interesting species <strong>of</strong> taxonomic value highly discussed among botanists regarding their<br />

rarity, systematic position <strong>and</strong> restricted distribution (Plates 7A & 7B).<br />

Details <strong>of</strong> the species<br />

1. Butea pellita Hook. f. (Fabaceae)<br />

A perennial herbaceous legume <strong>of</strong> subtropical pine forests. It remains dormant (underground) during autumn <strong>and</strong><br />

winter <strong>and</strong> sprouts up during the pre-monsoon showers in May. Leaves large, trifoliate, pubescent. Branches end in a<br />

terminal inflorescence. After seed fall above the ground portion <strong>of</strong> the plant dries <strong>of</strong>f <strong>and</strong> becomes dormant till the next<br />

summer. This plant is found only at a few locations like Patwadangar <strong>and</strong> Banoliya in Nainital Forest Division, both at<br />

an altitude <strong>of</strong> 1500-1600m above msl. This plant is locally called ‘Patwa’ <strong>and</strong> the name <strong>of</strong> the place Patwadangar<br />

means ‘The rocky hill full <strong>of</strong> Patwa’. The total population in this area is estimated to be around 100 plants.<br />

2. Symplocos ferruginea Roxb. (Styraceae)<br />

46<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

A medium sized evergreen tree, having restricted distribution, again around Patwadangar. It is easily identified by its<br />

large elliptic, serrate leaves. Petioles <strong>and</strong> veins underneath rusty. The inflorescence <strong>and</strong> peduncles are also rusty<br />

brown in colour, hence the specific name ‘ferruginea’. There may be around 20 trees only in this area. The other<br />

associates in this area are Symplocos crataegoides, Glochidion velutinum <strong>and</strong> Michelia kissopa.<br />

3. Toricella tiliaefolia DC. (Toricelliaceae)<br />

A small tree with large cordate leaves <strong>and</strong> is the only representative <strong>of</strong> the family Toricelliaceae. The leaves resemble<br />

those <strong>of</strong> the family Aristolochiaceae. There are only two populations identified so far, Guini B<strong>and</strong> near Birhi, where a<br />

small population is visible from the roadside <strong>and</strong> Patal Bhubaneswar, where there are a few isolated trees. Both the<br />

places are in Pithoragarh Forest Division <strong>and</strong> the altitude ranges from 1500-1900m above msl.<br />

4. Trachycarpus takil Becc. (Arecaceae)<br />

A medium sized palm thought to be endemic to the Kumaon <strong>and</strong> Western Nepal Himalayas. The only known natural<br />

populations are Girgaon near Kalamuni <strong>and</strong> Thalkedar in Pithoragarh Forest Division. The palm grows on steep cliffs<br />

<strong>and</strong> is easily identified by the terminal rosette <strong>of</strong> orbicular, palmate, plicate <strong>and</strong> deeply incised leaves with glaucous<br />

shining undersides. The leaf sheaths shred out into fibrous material remaining persistent on the stem for a long time at<br />

least below the terminal rosette. This species is <strong>of</strong>ten confused with the ornamental palm Trachycarpus fortunei<br />

commonly grown in Mussoorie <strong>and</strong> Nainital, which is distinguished by the strap like long ligule unlike the short pointed<br />

ligule <strong>of</strong> T. takil. The specific name originates from the local name <strong>of</strong> the palm, ‘Thakal’. One opinion is also that the<br />

specific name originates from the locality name Thalkedar. It is also possible that the name Thalkedar has come from<br />

‘Thakal Dhar’, meaning ‘the ridge <strong>of</strong> palms’. The species is under threat due to use <strong>of</strong> leaves for thatching, brooms <strong>and</strong><br />

ornamental purposes <strong>and</strong> also due to fires in the steep grassy slopes.<br />

5. Cyathea spinulosa Wall. (Cyatheaceae)<br />

Only tree fern found in the Himalayan region <strong>and</strong> is in restricted distribution unlike its common occurrence in the<br />

Western Ghats <strong>and</strong> North Eastern States. This fern is easily identified by its tree like trunk <strong>and</strong> a rosette <strong>of</strong> terminal<br />

tripinnate fronds with spiny petioles. Only three populations are identified so far, viz., below S<strong>and</strong>ev forests in Pithoragarh<br />

Forest Division, Birahi Ganga catchment in Badrinath Forest Division <strong>and</strong> above a l<strong>and</strong>slide on Gopeswar-Tangsa<br />

road in Kedarnath Wildlife Division. All these populations are in the average altitude <strong>of</strong> 1100-1300m above msl. The<br />

population on a stream across Gopeswar-Tangsa Road was washed <strong>of</strong>f in a l<strong>and</strong>slide in 2007 leaving behind only a<br />

few individuals <strong>and</strong> some regeneration.<br />

6. Ceropegia wallichii Wight. (Asclepiadaceae)<br />

An erect <strong>and</strong> beautiful herb recently discovered during a survey in the Himalayan Botanic Gardens at Nainital where a<br />

degraded forest l<strong>and</strong> was allowed to regenerate naturally by means <strong>of</strong> protection measures. This is a small perennial<br />

bushy plant unlike its counterparts which are climbers. The species is easily identified by the peculiar flower shape <strong>of</strong><br />

all Ceropegias <strong>and</strong> by the very long slender follicles with numerous pappous hairy seeds inside. The plant has since<br />

been preserved, multiplied <strong>and</strong> planted in other places inside the garden.

7. Phaius tankervillae (Banks) Blume (Orchidaceae)<br />

A ground orchid found in the swampy evergreen microclimates in the Sal forests <strong>of</strong> the Shiwalik <strong>and</strong> foothills <strong>of</strong> the<br />

Himalaya. This orchid was presumed to be extinct in the wild due to its heavy exploitation in the past for ornamental<br />

purposes. This species was recently rediscovered in a small population in a swamp near Gajar sot in Corbett National<br />

Park. The plant is easily identified by its long plicate leaves <strong>and</strong> the large showy inflorescence with brown tepals with<br />

white undersides. The labellum forms a small cylindrical tubular structure in the middle <strong>of</strong> the flower.<br />

8. Wallichia densiflora Mart. (Arecaceae)<br />

A dwarf palm endemic to Himalaya found in dense moist shady regions <strong>and</strong> is very rare <strong>and</strong> restricted in distribution.<br />

The palm can be easily identified by its size <strong>and</strong> large lobed pinnate leaves with sinuate margins <strong>and</strong> shiny, glaucous<br />

undersides. The inflorescence is a dense axillary spadix. This palm is found in extremely small populations, the main<br />

localities being Gajar swamp in Corbett National Park, Mundiapani <strong>and</strong> Domunda in Kalagarh Forest Division, Kyari in<br />

Ramnagar Forest Division <strong>and</strong> Dogaon water falls in Nainital Forest Division. The palm is <strong>of</strong> high ornamental value <strong>and</strong><br />

hence its exploitation has restricted its occurrence in rather inaccessible areas only.<br />

9. Glyceria tonglensis C.B. Clarke (Poaceae)<br />

A semi-aquatic grass found near the high altitude lakes <strong>and</strong> ponds <strong>and</strong> spends most <strong>of</strong> its life under submerged<br />

conditions <strong>and</strong> rest in the dried swampy portion <strong>of</strong> the lake side. The subsurface runners enable the species to extend<br />

all along the moist region around the lake. The plant can be easily identified by its branched panicle with stiff branches<br />

at an angle to the main rachis. The spikelets have several florets with overlapping glumes <strong>and</strong> blunt tips (Bor 1960).<br />

10. Dimeria ornithopoda Trin. (Poaceae)<br />

This is a very common ephemeral grass <strong>of</strong> mostly in peninsular <strong>India</strong>, but is found in the Himalayas in so far only one<br />

report from Chakori at 2000m altitude on a moist rocky ground, probably a granite outcrop, where it is found in a<br />

gregarious population. The other isolated record <strong>of</strong> this species is from Robber’s cave in Dehradun. The disjunct<br />

distribution <strong>of</strong> this grass species, that too at a high altitude, is a mystery to be solved.<br />

8.0 <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> Kedarnath Wildlife<br />

Sanctuary,Western Himalaya<br />

1Gajendra Singh & Ishwari Dutt Rai<br />

Wildlife Institute <strong>of</strong> <strong>India</strong>, Dehradun<br />

1gajendrawat@yahoo.com The Western Himalaya is well known for its floral, faunal, cultural <strong>and</strong> aesthetic values. Though it forms only about<br />

seven percent <strong>of</strong> <strong>India</strong>’s l<strong>and</strong> surface, it plays a major role in shaping the <strong>India</strong>n monsoon bestowing a tremendous life<br />

sustaining values to the <strong>India</strong>n subcontinent. The establishment <strong>of</strong> several protected areas (PAs) in recent years in the<br />

Himalaya as well as other parts <strong>of</strong> the country (Rodgers & Panwar 1988) raises hopes for the long term conservation <strong>of</strong><br />

representative ecosystems <strong>and</strong> biota. The existing PA network in the Himalaya covers diverse natural habitats for<br />

maximum species <strong>of</strong> flora <strong>and</strong> fauna but planning the proper size <strong>and</strong> shape <strong>of</strong> PAs suffers due to lack <strong>of</strong> information<br />

on the specific habitats <strong>of</strong> rare <strong>and</strong> endemic plants. Several workers have stressed the need for conservation <strong>of</strong><br />

threatened plants <strong>of</strong> Kedarnath Wildlife Sanctury. Patterns <strong>of</strong> their rarity <strong>and</strong> endemism are discussed along with their<br />

conservation status in <strong>and</strong> around the sanctuary.<br />

The Sanctuary<br />

The Kedarnath Wildlife Sanctuary (KWS) is one <strong>of</strong> the largest PAs (975 km 2 ) in the Western Himalaya, located in<br />

Chamoli district <strong>of</strong> Uttarakh<strong>and</strong>. It is bordered by high peaks viz., Kedarnath (6940m), M<strong>and</strong>ani (6193m) <strong>and</strong><br />

Chaukhamba (7068m) <strong>and</strong> extensive alpine meadows i.e., Kham, M<strong>and</strong>ani, P<strong>and</strong>avshera, Rudranath, Manpai in the<br />

north. The sanctuary covers a wide altitudinal range <strong>and</strong> has sizeable areas with limited human pressure. Hence, it<br />

harbours a great diversity <strong>of</strong> flora (>2000 species). However, some parts <strong>of</strong> the sanctuary which are heavily used by<br />

human beings for pilgrimage <strong>and</strong> livestock grazing, a few species have witnessed rapid decline during recent decades<br />

e.g. disappearance <strong>of</strong> Oaks, Taxus, Cypripedium, Dactylorhiza, Aconites <strong>and</strong> Picrorhiza kurrooa, etc.<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Fifteen species <strong>of</strong> vascular plants found in KWS have been listed in the Red Data Book <strong>of</strong> <strong>India</strong>n plants (Rao et al. 2003)<br />

under the different threat categories (Table 1). These include Endangered (2), Vulnerable (2), Rare (3) <strong>and</strong> Indeterminate<br />

(8). In addition, four species endemic to <strong>India</strong>n Himalayan Region (IHR) have been recorded from the sanctuary which<br />

falls under restricted range species (Dhar <strong>and</strong> Samant 1993, Samant et al. 1998, Samant 1999). Among these, three<br />

species (Aconitum heterophyllum, Allium stracheyi <strong>and</strong> Angelica glauca) are endemic to Himalayan region <strong>and</strong> one<br />

species (Falconeria himalaica) is endemic to Uttarakh<strong>and</strong>.<br />

Critical habitats for plants conservation in <strong>and</strong> around Kedarnath WS<br />

Kedarnath WS has several extensive alpine meadows <strong>and</strong> quite a few dense broad leave forests in the fringes <strong>of</strong> the<br />

sanctuary which forms various habitats for the rare <strong>and</strong> threatened species. Following are the few critical habitats <strong>and</strong><br />

corresponding species (Plate 8) within the sanctuary:<br />

1. Mixed herbaceous meadows : Gentle <strong>and</strong> moist meadows above tree line have a large number <strong>of</strong> plant species<br />

e.g., Ranunculus hirtellus, Bistorta affinis, B. vivipara, Anemone rivularis, Geranium wallichianum, Potentilla<br />

atroisanguinea, P. argerophylla, Geum elatum. These meadows support high value medicinal <strong>and</strong> aromatic plants<br />

such as Aconitum heterophyllum, A. violaceum, A. ferox, Arnebia benthamii, Pichrorhiza kurrooa <strong>and</strong> Gentiana spp.<br />

2. Caves <strong>and</strong> Caverns : Rock crevices <strong>and</strong> caverns are shaded areas close to tree line. These habitats support some<br />

<strong>of</strong> the specific species e.g., Circaeaster agrestis, Woodsia alpina, Chamabania cuspidata, Parietaria debilis <strong>and</strong><br />

Primula edgeworthii.<br />

3. Boulders <strong>and</strong> scree slopes : In the high altitude (above 3600m) regions <strong>of</strong> the sanctuary, especially the sites<br />

exposed to snow blizzard are characterized by dwarf cushionoid species clinging to the ground. Some <strong>of</strong> the species<br />

on moist aspects covered by boulders at such heights are Saussurea obvallata, S. graminifolia, Falconeria himalaica,<br />

Bergenia strachyei, Nardostachys gr<strong>and</strong>iflora, Allium stracheyi, Rheum moorcr<strong>of</strong>tianum, Pleurospermum densiflorum.<br />

These species are favoured for grazing by sheep, goats as well as blue sheep.<br />

4. Stream courses : The stream courses in the sub-alpine <strong>and</strong> alpine regions <strong>of</strong> the sanctuary are mainly dominated<br />

by Caltha palustris, species <strong>of</strong> Corydalis, Pedicularis <strong>and</strong> Primula. Other species frequently seen in such habitats are<br />

Meconopsis aculeata, Equisetum debile <strong>and</strong> Swertia speciosa.<br />

5. Alpine moist scrub : Shady moist slopes especially in adjacent to timber line between 3300-3700m asl <strong>of</strong>ten have<br />

extensive patches <strong>of</strong> dwarf Salix lindleyana, Cassiope fastigiata <strong>and</strong> Rhododendron anthopogon. The mat forming<br />

species support some <strong>of</strong> the threatened species e.g., Cypripedium himalaicum, C. cordigerum, C. elegans <strong>and</strong> Picrorhiza<br />

kurrooa.<br />

6. Temperate oak forests : Moist temperate forest <strong>of</strong> the region is mainly dominated by Banj oak (Quercus<br />

leucotrichophora), Rhododendron arboreum <strong>and</strong> Lyonia ovalifolia. These habitats are under tremendous pressure <strong>of</strong><br />

human activities. Certain threatened plants e.g., Dendrobium normale, Paeonia emodi, Zeuxine flava are associated<br />

with Banj Oak forests.<br />

Above mentioned habitats need to be given high priority for conservation in Kedarnath Wildlife Sancturary. Some <strong>of</strong> the<br />

important localities suggested for restoration <strong>and</strong> monitoring <strong>of</strong> these habitats are Kedarnath, Kham, Tungnath <strong>and</strong><br />

Bansinarayan. The impact <strong>of</strong> man <strong>and</strong> his domestic animals on the vegetation is seen everywhere. Excessive lopping<br />

in the temperate region <strong>and</strong> overgrazing <strong>of</strong> high altitude pastures by sheep, goats <strong>and</strong> buffaloes is an important factor<br />

responsible for change in the composition <strong>of</strong> vegetation in many regions in the sanctuary. Excess <strong>of</strong> tourism <strong>and</strong><br />

pilgrimage has been an important reason for degradation <strong>of</strong> habitats <strong>and</strong> species. During peak summer, one can

holy shrine <strong>of</strong> Kedarnath, Madhmaheshwar, Tungnath <strong>and</strong> Rudranath. Several herbs with beautiful flowers are plucked<br />

by tourists just for fun.<br />

Conservation <strong>of</strong> these valuable species would not be possible without the active participation <strong>of</strong> the local people. It is<br />

high time that the management authorities <strong>of</strong> KWS initiate dialogues with the temple management committees / traots<br />

at each <strong>of</strong> the five Kedars to set aside a part <strong>of</strong> temple premise for protection <strong>of</strong> habitats <strong>and</strong> not to allow collection <strong>and</strong><br />

sale <strong>of</strong> wild flowers such as Brahamkamal at these places. A new approach <strong>of</strong> habitat conservation rather than species<br />

conservation needs to be established. Conservation <strong>of</strong> forests at fringes <strong>of</strong> villages needs to be initiated to save various<br />

components <strong>of</strong> these forests to improve the habitat conditions.<br />

Picrorhiza kurrooa Royle ex Benth. (Scrophulariaceae), popularly known as Kutki, Kadawi or Kuru, is not a new name<br />

for Ayurvedic practitioners, Vaids, Hakims <strong>and</strong> herbal industry. It is also not a new plant for botanists <strong>and</strong> plant ecologists.<br />

However, rapid decline <strong>of</strong> this species from wild during recent years is a new thing which has serious conservation<br />

implications. The increasing market dem<strong>and</strong> <strong>of</strong> the plant has led to unscientific, unmanaged <strong>and</strong> overharvesting <strong>of</strong> the<br />

plant, raising concern amongst many ecologists, scientists <strong>and</strong> conservationists (Rai & Sharma 2000, Uniyal et al.<br />

2002, Rawat 2005). As a result, the species has been included in the Negative List <strong>of</strong> Export by the Govt. <strong>of</strong> <strong>India</strong> <strong>and</strong><br />

Appendix II <strong>of</strong> CITES. Based on the extensive collection for trade <strong>and</strong> dwindling population in the wild, the plant has<br />

also been categorized as Vulnerable in the Red Data Book (Nayar & Sastry 1987) <strong>and</strong> as ‘Endangered’ as per<br />

Conservation Assessment <strong>and</strong> Management Planning (CAMP) workshop (Ved et al. 2003).<br />

This article deals with the status <strong>and</strong> distribution <strong>of</strong> P. kurrooa in the Himalayan region. Current levels <strong>of</strong> extraction <strong>and</strong><br />

trade from different regions <strong>and</strong> conservation implications are discussed.<br />

The Plant: Habit, Habitat <strong>and</strong> Distribution<br />

P. kurrooa is a perennial herb with stout <strong>and</strong> creeping rhizome (Plate 9). Leaves are simple, spathulate with serrate<br />

margins. Flowers purplish blue in terminal racemes, seen during July-August. Its fruiting period is September-October.<br />

It is generally found in association with Salix lindleyana, Nardostachys jatamansi, Gaultheria trichophylla, Selinum<br />

c<strong>and</strong>ollii <strong>and</strong> Meconopsis aculeata. In <strong>India</strong> P. kurrooa is mainly distributed in the North-West (2A), West (2B) <strong>and</strong> Trans-<br />

Himalayan (1A) biogeographic zones. It has also been reported from some parts <strong>of</strong> central <strong>and</strong> North-east Himalaya<br />

(Rai & Sharma 2002, Haridasan et al. 2002). In Uttarakh<strong>and</strong> it has been reported from Valley <strong>of</strong> flowers National Park<br />

(VOF NP), Kedarnath Wildlife Sanctuary (KWLS), N<strong>and</strong>a Devi Biosphere Reserve (NDBR), <strong>and</strong> alpine ranges <strong>of</strong><br />

Ralam, Gori, Pindar, Bhagirathi, Yamuna, Dhauli <strong>and</strong> Kali valleys (Uniyal 1968, Rawat 1983, Kala et al. 1998, Uniyal et<br />

al. 2002, Rawat 2005, Semwal et al. 2007) In Himachal Pradesh its distribution ranges from as far as Trans-Himalayan<br />

regions <strong>of</strong> Lahaul-Spiti to alpine regions <strong>of</strong> M<strong>and</strong>i, Kullu, Chamba, Kinnaur <strong>and</strong> Kangra districts. It has also been<br />

reported from Great Himalayan National Park (GHNP), Dhauladhar WLS (DWLS) <strong>and</strong> Kugti WLS (KWLS) (Shabnam<br />

1964, Kala 2000, Singh & Rawat 2000, Samant et al. 2002, Uniyal et al. 2006). In Kashmir it has been reported from<br />

Gurez, Gulmarg, Lolab Karna <strong>and</strong> Padar ranges (Kaul & H<strong>and</strong>a 2002). P. kurrooa, like many other medicinal plants<br />

also has habitat specificity. It generally occurs 3600m above msl in the moist rocky habitats with well drained soil (Plate<br />

9). As rhizome is the main source <strong>of</strong> the drug, the collectors uproot the entire plants thus affecting regeneration <strong>and</strong><br />

population <strong>of</strong> P. kurrooa <strong>and</strong> degrading its habitat.<br />

Population Status, Regeneration <strong>and</strong> Cultivation Efforts<br />

Information on population <strong>and</strong> regeneration <strong>of</strong> medicinal plants is not only important to assess their availability in wild<br />

but is also a key requirement for threat categorization. Though emphasis on generating information on the population<br />

<strong>of</strong> medicinal plants has been laid, little work has actually been done in this aspect. One <strong>of</strong> the reasons is the difficult<br />

terrain <strong>and</strong> unfavourable weather <strong>of</strong> high altitudes where these plants grow <strong>and</strong> the other is the lack <strong>of</strong> enthusiasm to<br />

work in the Himalaya. Recently, some workers have collected data on the distribution, abundance <strong>and</strong> uses <strong>of</strong> some<br />

important medicinal <strong>and</strong> aromatic plants <strong>of</strong> Himalaya including P. kurrooa (Singh 1999, Kala 2000, Rai et al. 2000,<br />

Uniyal et al. 2002, Kala 2004, Rawat 2005, Uniyal et al. 2006, Semwal et al. 2007). It has been proven through some<br />

habitat based studies that P. kurrooa has restricted <strong>and</strong> localized distribution. Its highest density has been reported from<br />

moist rocky slopes <strong>and</strong> under scrub habitats <strong>of</strong> >3600m altitudes (Uniyal et al. 2002, Semwal et al. 2007). In alpine<br />

ranges <strong>of</strong> Gori valley, its mean density was 3.89 individuals/ m 2 . It was highest (12.92 individuals/m 2 ) in the moist rocky<br />

slopes <strong>and</strong> least in the grassy slopes (0.085 individuals / m 2 ). It was completely absent in the undulating <strong>and</strong> marsh<br />

meadows (Uniyal et al. 2002) whereas in the VOF NP, the population <strong>of</strong> P. kurrooa was 4.5 individuals/ m 2 (Kala et al.<br />

1998). In another assessment <strong>of</strong> P. kurrooa from different valleys <strong>of</strong> Uttarakh<strong>and</strong>, the mean density <strong>of</strong> P. kurrooa has<br />

been reported to be 2.21 individuals / m 2 . The highest population (1.61 individuals / m 2 ) being from alpine meadows <strong>of</strong><br />

Gidara while lowest (0.11 individuals / m 2 ) was in the Kushkalyani (Rawat 2005). In Kedarnath WLS mean density <strong>of</strong> P.<br />

kurrooa was 2.2 individuals/ m 2 . It was highest in the under scrub (5.6 individuals/ m 2 ) <strong>and</strong> steep slopes (5.2 individuals/<br />

m 2 ) habitats while it was lowest (1.21 individuals / m 2 in the undulating alpine meadows (Semwal et al. 2007). However,<br />

highest density estimates for P. kurrooa have been reported from the Trans-Himalayan region. Distribution <strong>of</strong> P. kurrooa<br />

was very localized <strong>and</strong> found in patches <strong>and</strong> a density <strong>of</strong> 70.6 individual/ m 2 in Tarbak region <strong>of</strong> Spiti valley has been<br />

reported (Kala 2000). These studies indicate that the species not only has restricted <strong>and</strong> localized distribution but their<br />

population has also been influenced due to anthropogenic activities. None <strong>of</strong> the studies so far have actually collected<br />

information on its regeneration <strong>and</strong> taken time series information. Still, the baseline information that has been generated<br />

will certainly help in future monitoring <strong>of</strong> the plant population <strong>and</strong> its habitats. However, research on its cultivation <strong>and</strong><br />

propagation methods has already provided very good results. A very high ranking has been given to P. kurrooa (ranked<br />

II nd ) for ex situ cultivation in Himachal Pradesh. Its cultivation prospects have been ranked “A” (second highest rank) <strong>and</strong><br />

marketing at national <strong>and</strong> international levels is also “A” (Badola 2002). P. kurrooa can be propagated through seeds as<br />

well as by vegetative means. Cultivation by vegetative means is more advantageous for eliminating difficulties associated<br />

with seed germination <strong>and</strong> seedling survival. It also reduces the length <strong>of</strong> cultivation cycle (Nautiyal 1995, Sundriyal &<br />

Sharma 1995). It has been reported that maximum seed production in P. kurrooa takes place when it grows under<br />

scrub dominated canopy (Nautiyal & Nautiyal 2004). Hence it’s intercropping with saunf <strong>and</strong> Digitalis purpurea gave a<br />

better yield. Its production was 320kg/ha indicating a benefit <strong>of</strong> Rs. 87,600/ha when harvested during third year <strong>of</strong><br />

growth at 1800 m elevation in the Himalaya. It has been found that post harvest drying at room temperature (15-20 o C)<br />

retains high picrotin <strong>and</strong> picrotoxin. Whereas drying in direct sun or in oven decreases the active compounds rapidly<br />

(Nautiyal & Nautiyal 2004). Besides these, plant tissue culture technique can also be employed for its clonal multiplication<br />

<strong>and</strong> it can provide an effective strategy for its conservation (Ahuja 2002). Though, it has been found through cost-benefit<br />

analysis that cultivation <strong>of</strong> P. kurrooa (Rs. 88284) can be far more pr<strong>of</strong>itable than cash crops such as potatoes (Rs.<br />

12600) <strong>and</strong> rajma (Rs.5325), still no large scale cultivation <strong>of</strong> P. kurrooa is done in high altitude areas. Cultivation is<br />

restricted either to research sites developed by some institutions in collaboration with villagers (Haridasan et al. 2002,<br />

Kaul & H<strong>and</strong>a 2002, Rai & Sharma 2002, Ahuja 2002) or to few interior villages in Uttarakh<strong>and</strong> (Silori & Badola 2000,<br />

Uniyal et al. 2002). Most <strong>of</strong> the cultivation done in these villages is also through transplantation <strong>of</strong> species from wild to<br />

fields (Virdi 2002) <strong>and</strong> not through proper cultivation techniques. The main reason for which is the lack <strong>of</strong> proper<br />

information <strong>and</strong> guidance to villagers <strong>and</strong> problems associated with storage, transportation <strong>and</strong> marketing <strong>of</strong> medicinal<br />

plants. Hence, besides cultivation, research efforts on above mentioned aspects should also be undertaken for<br />

community based cultivation <strong>of</strong> P. kurrooa. Demonstration <strong>of</strong> propagation techniques <strong>and</strong> distribution <strong>of</strong> elite propagules<br />

to farmers interested in their commercial cultivation will not only generate self employment opportunities for the local<br />

people but will also pave the way for its in situ conservation.<br />

Extraction <strong>and</strong> Trade<br />

The roots <strong>and</strong> rhizomes <strong>of</strong> P. kurrooa contain 26-27% Picrorhizin in addition to other active constituents such as<br />

kutkoside. Picrorhizin is a major constituent <strong>of</strong> many important liver <strong>and</strong> stomach medicines. Besides, it is also used in<br />

drugs prescribed for treatment <strong>of</strong> respiratory diseases <strong>and</strong> allergic manifestations (Sarin 2008). Traditionally the plant


was collected during August – September, however, in order to maximize economic gains, now the collection starts in<br />

month <strong>of</strong> July itself. The entire plant is uprooted <strong>and</strong> material is cleared <strong>of</strong> adhering rootlets <strong>and</strong> dried in sun for a week.<br />

It is largely collected from Jammu <strong>and</strong> Kashmir, Himachal Pradesh, Uttarakh<strong>and</strong> <strong>and</strong> Sikkim. Annual transaction <strong>of</strong><br />

10,000 kg <strong>of</strong> P. kurrooa takes place in Delhi market. During 1998-99 it was sold at a price <strong>of</strong> Rs. 100-150/ kg which has<br />

increased to Rs. 230-280/kg in 2006 (Samant et al. 2002), while local people who actually traverse high altitudes to<br />

collect the plant still get a meager sum <strong>of</strong> Rs.10-60/kg (Awasthi <strong>and</strong> Uniyal 2003). Global supply (excluding China <strong>and</strong><br />

Pakistan) <strong>of</strong> P. kurrooa is around 375 tons with <strong>India</strong> contributing around 70 tons next only to Nepal (250 tons). In order<br />

to meet the dem<strong>and</strong> <strong>of</strong>ten Lagotis cashmiriana is adultered with P. kurrooa. In Nepal, P. kurrooa is traded in the name<br />

<strong>of</strong> Neopicrorhiza scrophulariiflora (Shrestha <strong>and</strong> Jha 2009).<br />

Because <strong>of</strong> its great therapeutic importance, dem<strong>and</strong> for P. kurrooa is very high <strong>and</strong> steady in the market. It is one <strong>of</strong> the<br />

top 15 plant species traded in <strong>India</strong> (Malaisamy <strong>and</strong> Ravindran 2003). The dem<strong>and</strong> for P.kurrooa is more than 5000<br />

tons; however, its supply is less than 100 tons (Kumar 2006). With an annual growth <strong>of</strong> 20% in Ayurvedic medicine<br />

sector dem<strong>and</strong> <strong>of</strong> medicinal plants has also increased by 11.1 % in recent years, resulting in an augmentation in the<br />

extraction <strong>of</strong> P. kurrooa. It has been reported that earlier (1988-89) only 1.468 tons <strong>of</strong> P. kurrooa was extracted from the<br />

entire state <strong>of</strong> Himachal Pradesh (Sharma 1995). Today, the extraction is 10 times higher (Singh 1999). Similar<br />

patterns have been reported from Uttarakh<strong>and</strong>, where more than 5 tons <strong>of</strong> P. kurrooa was extracted by 12 villages <strong>of</strong><br />

Gori valley during 2000-01 (Virdi 2004). From Sikkim also, P. kurrooa to a tune <strong>of</strong> 6 tons is annually extracted (Rai et al.<br />

2000). The amount <strong>of</strong> extraction figure available is just the tip <strong>of</strong> the iceberg as most <strong>of</strong> the trade in medicinal plants is<br />

illegal <strong>and</strong> secretive <strong>and</strong> data for which are still not available. Though cultivation practices for P. kurrooa have been<br />

developed (Nautiyal et al. 2001), still 90% <strong>of</strong> the plant material in trade comes from wild <strong>and</strong> is harvested following<br />

destructive methods. This has threatened the status <strong>of</strong> P. kurrooa in wild. As a result, P. kurrooa once plentiful, is now<br />

restricted to areas not easily accessible to man. A large majority <strong>of</strong> collectors have stated unambiguously that there is<br />

a decrease in the availability <strong>of</strong> medicinal plants. Now they have to spend more time <strong>and</strong> cover long distance for<br />

collecting same quantity <strong>of</strong> medicinal plant (Kumar 2006). Thus, it seems time is not far when these species will be<br />

locally extinct. A very good example <strong>of</strong> this is the Chhangu <strong>and</strong> Lachung valleys in Sikkim where rampant collection <strong>of</strong><br />

Podophyllum hex<strong>and</strong>rum <strong>and</strong> Panax pseudo- ginseng have now made these areas devoid <strong>of</strong> both these herbs. Another<br />

important threat to its habitat highlighted recently is the complete receding <strong>of</strong> small glaciers (Shrestha & Jha 2009). On<br />

one h<strong>and</strong> there is dearth <strong>of</strong> information on the ecology, distribution <strong>and</strong> population <strong>of</strong> P. kurrooa <strong>and</strong> on other h<strong>and</strong> its<br />

population <strong>and</strong> habitat is shrinking.<br />

Conservation <strong>and</strong> Management Implications<br />

Distribution, Status <strong>and</strong> Conservation <strong>of</strong> Picrorhiza<br />

kurrooa in the Himalayan Region<br />

Keeping in view the status <strong>of</strong> P. kurrooa in wild, its sensitivity to anthropogenic impacts <strong>and</strong> its increasing dem<strong>and</strong> in the<br />

market, it has been listed among top 20 species prioritized for conservation <strong>and</strong> development (Dhar et al. 2000).<br />

National medicinal plant board (NMPB) has also identified P. kurrooa for conservation <strong>and</strong> propagation through its<br />

various schemes. A total <strong>of</strong> 212 acres <strong>of</strong> l<strong>and</strong> has been supported by NMPB for cultivation <strong>of</strong> P. kurrooa (which has<br />

increased from 7 acres in 2002-03 to 97 acres in 2005-06) (Kala & Sajwan 2007). It has already been provided<br />

protection under various conservation initiatives such as CITES, Red Data Book <strong>and</strong> IUCN list <strong>of</strong> threatened plants.<br />

Classification <strong>of</strong> species based on its area, distribution, abundance <strong>and</strong> use value at local <strong>and</strong> regional level is not only<br />

useful for its conservation but would also help in its proper management. Based on above mentioned classification<br />

P.kurrooa has been listed in RDHP (Restricted distribution <strong>and</strong> heavy pressure) category for alpine areas <strong>of</strong> Gori valley<br />

<strong>and</strong> KWLS (Uniyal et al. 2002, Semwal et al. 2007). For some other parts <strong>of</strong> Uttarakh<strong>and</strong> it has been listed as LCHP<br />

(locally common <strong>and</strong> heavy pressure) (Rawat 2005). Based on this criterion, some P. kurrooa specific conservation<br />

plots in wild should be marked in different valleys. Similarly, areas already reported to be rich in population <strong>of</strong> P. kurrooa<br />

should be marked as control sites for future monitoring <strong>and</strong> repeated sampling.<br />

P. kurrooa being in steady dem<strong>and</strong> has very high harvesting pressure. It is reported that a total <strong>of</strong> 286 plants as shoot part<br />

<strong>and</strong> 500 as root parts are harvested to make a kilogram weight <strong>of</strong> P. kurrooa (Rai et al. 2000). Hence collection from wild<br />

should be done on a rotational basis which will help in the recuperation <strong>of</strong> the area <strong>and</strong> a sustainable harvest. It has also<br />

been reported that plants in the alpine areas complete their reproductive phase during the months <strong>of</strong> September <strong>and</strong><br />

October. Hence harvesting should be done during the month <strong>of</strong> October when active constituents have the highest<br />

proportion (Nautiyal & Nautiyal 2004). This knowledge should also be spread amongst the collectors so that harvest is<br />

done after seed set.<br />

Awareness generation amongst the local people <strong>and</strong> collectors will go a long way in medicinal plant conservation.<br />

Elite plant population with complete agro-technique package that includes good agricultural practices, good collection<br />

practices <strong>and</strong> post harvest management should be made available to the farmers for cultivation. Associated with<br />

cultivation is the marketing <strong>and</strong> trade. Trade related studies are very few <strong>and</strong> therefore need to be proposed <strong>and</strong> carried<br />

forward. We still do not have quantitative information on the distribution <strong>and</strong> population <strong>of</strong> medicinal plants from many<br />

interior areas <strong>of</strong> the Himalaya. This has been pointed out to be one <strong>of</strong> the major drawbacks in medicinal plant research.<br />

Therefore, concentrated surveys <strong>and</strong> exploration is the need <strong>of</strong> the hour. Studies on impact <strong>of</strong> changing climate on<br />

these rare <strong>and</strong> threatened plants <strong>of</strong> Himalaya should also be taken up.<br />

Introduction<br />

10.0 Endemic <strong>and</strong> <strong>Threatened</strong> Orchids <strong>of</strong><br />

Sikkim <strong>and</strong> Their Conservation<br />

S.Z. Lucksom<br />

Himalayan Zoological Park, Gangtok<br />

Government <strong>of</strong> Sikkim<br />

szlucksom@yahoo.com<br />

Sikkim (7096 km 2 ; 27º 5’ to 28º 9¢ N latitudes <strong>and</strong> 87º 59' to 88º 56' E longitudes), is the smallest state <strong>of</strong> <strong>India</strong>n Union,<br />

well known for its diverse eco-climatic zones <strong>and</strong> rich biological diversity. The major climatic zones in the state are<br />

Tropical, Sub-Tropical, Temperate, Dry-Alpine <strong>and</strong> Wet-Alpine. Through deep valleys, especially along Teesta, the<br />

hot <strong>and</strong> moist tropical climate penetrates right into the heart <strong>of</strong> the state, providing hotter southern <strong>and</strong> cooler northern<br />

slopes. Because <strong>of</strong> these geographical features, the state harbours a range <strong>of</strong> interesting plants including orchids. The<br />

state surpasses all other states <strong>of</strong> <strong>India</strong> in the diversity <strong>of</strong> orchids, trailing just behind Arunachal Pradesh. However, if the<br />

ratio <strong>of</strong> orchids with l<strong>and</strong> mass is compared, the state ranks among the richest areas in the world. Arunachal Pradesh,<br />

whose geographical area is more than eleven times that <strong>of</strong> Sikkim has only 620 orchid species <strong>and</strong> Bhutan whose<br />

geographical region is six times the size <strong>of</strong> Sikkim has only 372 orchid species as compared to 523 species in Sikkim.<br />

One more reason for high diversity <strong>and</strong> endemism among orchids <strong>of</strong> Sikkim could be its unique topography. The horse<br />

shoe shaped mountain ranges on the west act as a barrier for dispersal <strong>of</strong> many species <strong>and</strong> strongly influence<br />

regional climate. This has led to the formation <strong>of</strong> unique habitats in the state. Besides, the windward side on the<br />

southern part <strong>of</strong> the Dongkya range receives the maximum monsoon rain giving rise to wet alpine type <strong>of</strong> climate. The<br />

general trend <strong>of</strong> mountain ranges in Sikkim is from east to west-Mt P<strong>and</strong>im (6691m), Mt Simvo (6811m), Mt Siniolchu<br />

(6887m), Mt Kabru (7338m) <strong>and</strong> Mt Narsing (5825m), but there are two main long south north directed ridges running<br />

parallel to each other 64 to 96 km apart. The Singalila range which is about 64 km long, almost starts from plains level,<br />

separates Sikkim from Nepal in the West <strong>and</strong> culminates near its northern extremity in world’s third highest mountain,<br />

the Mt Khanchendzonga (8598m). The Chlola range in the East, in comparison is much higher in elevation <strong>and</strong><br />

separates Sikkim from Bhutan East. Besides that there is the deep Chumbi valley separating Sikkim <strong>and</strong> Bhutan. There<br />

is another central longitudinal ridge which separates the great Teesta catchment in the East from the Rangit catchment<br />

in the west, culminating at Moinam Peak (3234m). In general, the valleys are narrow at the top <strong>and</strong> broader at the base.<br />

But in Sikkim valleys are broad at the top. Broad valleys like Donkong, Gyamchona, Cholamu <strong>and</strong> Muguthang are<br />

stretches <strong>of</strong> plain areas with unique faunal <strong>and</strong> floral diversity similar to that <strong>of</strong> Tibetan plateau.<br />

Studies on Orchids <strong>of</strong> Sikkim<br />

First collection <strong>of</strong> orchid in the state was done by Griffith, followed by Cathcart, then Sir J D Hooker (Mathew 1970).<br />

Kataki et al. (1984) documented the threatened <strong>and</strong> endemic orchids <strong>of</strong> Sikkim. King & Pantling were the first to carry<br />

out orchid surveys in Sikkim during 1898, that led to the publication <strong>of</strong> “The Orchids <strong>of</strong> Sikkim Himalaya”. These<br />

authors recorded 448 species <strong>of</strong> orchids from the state. Despite several floristic surveys in the state no comprehensive<br />

account <strong>and</strong> update on the orchids <strong>of</strong> state was available until recently when the author initiated systematic studies in<br />

1986. More recent works on the orchids <strong>of</strong> the state include Shukla et al. (1998), Sathish kumar (2001). A detailed<br />

investigation for two decades has resulted in several new discoveries <strong>and</strong> new records. Presently, the state has more<br />

than 523 species spread over 134 genera (Lucksom 2007). It is to be noted that still there are quite a few underexplored<br />

<strong>and</strong> virgin forests which may yield several interesting varieties <strong>and</strong> new records in the state.<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

The sub-tropical belt (1000 – 1500 m asl) in the state is richest in terms <strong>of</strong> orchid diversity. The following table gives an<br />

idea about the distribution <strong>of</strong> orchids in various altitudinal zones (though there is some overlap):<br />

Endemic <strong>and</strong> <strong>Threatened</strong> Orchids <strong>of</strong><br />

Sikkim <strong>and</strong> Their Conservation<br />

massive afforestation <strong>and</strong> plantation <strong>of</strong> several miscellaneous species such as Populus gamblei might have affected<br />

the vegetation structure <strong>and</strong> micro-habitat <strong>of</strong> many orchids leading to their decline. Close to Pabong, there is a small<br />

town named as Sintam. This town also had a good population <strong>of</strong> Dendrobium aphyllum. However, there has been a<br />

decline in tree cover due to mushrooming <strong>of</strong> buildings <strong>and</strong> other developmental activities. Even now a few scattered<br />

trees continue to support good population <strong>of</strong> these orchids.<br />

In the deep wooded areas where the tree canopy is very high <strong>and</strong> where no sun rays can penetrate into the forest floor,<br />

we do not find any epiphytic orchids. In such areas especially between 2000 – 2700m altitude several saprophytic or<br />

holomycotrophic orchids such as Aphyllochis montana, A. alpina, Galeola falconeri, G. lindleyana <strong>and</strong> G. cathcartii can<br />

be seen. Some orchids e.g., Rhynchostylis retusa <strong>and</strong> Aerides multiflora show close affinity with their host trees. These<br />

two orchid species are seen growing pr<strong>of</strong>usely on Mangifera indica <strong>and</strong> Polyalthia longifolia near Siliguri at Salugarh<br />

on both sides <strong>of</strong> the National Highway. But as soon as one leaves the area, both sides <strong>of</strong> the National Highway are lined<br />

with tall trees <strong>of</strong> Shorea robusta. Though these trees are full <strong>of</strong> other types <strong>of</strong> orchid species yet not a single tree is seen<br />

with the plants <strong>of</strong> Rhynchostylis retusa <strong>and</strong> Aerides multiflora. But these two species suddenly reappear in small<br />

population at Ranpo Baghey area. Rhynchostylis retusa has been seen up to 1600 m. Similarly, at Mangley (West<br />

Sikkim) populations <strong>of</strong> Aerides multiflora can be seen growing naturally at ca 1300 m. Occurrence <strong>of</strong> Zeuxine<br />

seidenfadenii Deva & Naithani was first reported in the state by Deva <strong>and</strong> Naithani in 1986. Present author confirmed<br />

its presence in the Sub-tropical mixed deciduous forest at an altitude <strong>of</strong> 900m.<br />

Bulbophyllum sterile (Lam.) Suresh grows frequently in Rangit valley Legshep at 600m altitude in West Sikkim <strong>and</strong><br />

up to 2000m altitude at Rumtek in East Sikkim. It can be seen <strong>of</strong>ten on Schima wallichii below Forest Secretariat<br />

Building at Gangtok, Sikkim. N.R. Pearce & P.J. Cribb the authors <strong>of</strong> “Orchids <strong>of</strong> Bhutan” have not named the places <strong>of</strong><br />

its occurrence in Bhutan; rather they have mentioned the species location in the state <strong>of</strong> Sikkim. Even the orchid<br />

species in the list <strong>of</strong> Eastern Arunachal Pradesh by A.N Rao <strong>and</strong> Ajay Rastogi have not named the place <strong>of</strong> its occurrence.<br />

But its presence in Nepal is mentioned in “The Orchids <strong>of</strong> Nepal Himalaya” by N.L.Banerjee <strong>and</strong> Prabha Pradhan.<br />

Hence it can be said that Sikkim <strong>and</strong> Eastern Nepal form the seat <strong>of</strong> origin <strong>of</strong> this species.<br />

Hara (1971) reported the distribution <strong>of</strong> Dactylorhiza hatagirea (D. Don) Soo from Kashmir to Bhutan. However, Pearce<br />

<strong>and</strong> Cribb as well as A. Nageswara Rao <strong>and</strong> Ajay Rastogi have not listed the species from Bhutan <strong>and</strong> Arunachal<br />

Pradesh. In Sikkim the species is not yet reported; rather it is always confused with Gymnadenia orchidis whose under<br />

ground tubers resemble that <strong>of</strong> Dactylorhiza hatagirea. Tubers <strong>of</strong> G. orchidis are short, joined in halfway whereas the<br />

tubers <strong>of</strong> Dactylorhiza hatagirea are longer, tubular <strong>and</strong> joined at the base. Besides that the flowers in former are much<br />

smaller <strong>and</strong> compact but tubular head as compared to latter.<br />

Cypripedium cordigerum D.Don has been reported from Jammu & Kashmir to Nepal (Deva <strong>and</strong> Naithani 1986). So<br />

far this species has not been reported from Sikkim. But Pears <strong>and</strong> Cribb have reported it from various parts <strong>of</strong> Bhutan.<br />

This needs to be verified.<br />

After sudden disappearance <strong>of</strong> Cymbidium whiteae King & Pantling, an endemic orchid from the Gangtok town, several<br />

individuals <strong>and</strong> institutions became concerned. Consequently two schools <strong>of</strong> thought emerged out on this issue <strong>of</strong> how<br />

<strong>and</strong> why the species disappeared from the place <strong>of</strong> its discovery. One school <strong>of</strong> thought is <strong>of</strong> the opinion that removal<br />

<strong>of</strong> trees is the main cause <strong>of</strong> the disappearance. But on the contrary, the other school <strong>of</strong> thought is <strong>of</strong> the opinion that the<br />

disappearance is due to over plantation. Based on a careful analysis the author came to the conclusion that, unlike<br />

other orchid species, Cymbidium whiteae may be very sensitive to air pollution. Because <strong>of</strong> this fact the species has<br />

totally vanished from Gangtok from where its first discovery was made by Mrs Claude White, the wife <strong>of</strong> political agent<br />

during 1989. Till late sixties its presence was reported from Gangtok. But now it is no more there, even when the habitat<br />

<strong>of</strong> Gangtok town is as it was before; even when the populations <strong>of</strong> preferred host trees <strong>of</strong> Engelhardtia spicata are in<br />

good numbers. It is also possible that certain pollinators have vanished from Gangtok town due to pollution. But the<br />

species can be seen in good number at Rumtek forest, the opposite hill <strong>of</strong> Gangtok town where pollution is almost nil<br />

as compared to Gangtok. This shows that the main cause <strong>of</strong> disappearance <strong>of</strong> the species is air pollution.<br />

Till 1990 Dendrobium amoenum used to occur commonly at altitude between 900 – 1600 m in Sikkim. Till then there<br />

was no report <strong>of</strong> the species from Gangtok town. But during 1990 its presence was observed in Gangtok town at 1800<br />

m. Now it is very common around Gangtok town especially on the bark <strong>of</strong> Alnus nepalensis trees. Some tall trees <strong>of</strong><br />

Alnus nepalensis in B.S.I. campus are laden with the species. Similarly, Cleisostoma linearilobulatum (Seidenf. <strong>and</strong><br />

Smitin<strong>and</strong>) Garay was never reported by King <strong>and</strong> Pantling within the greater Sikkim. But during recent survey, the<br />

author discovered this species occurring from 700m to 1200m altitude. But then its occurrence was only up to 1200m.<br />

More recently it has been found on the Pear trees at 2000m in Rumtek Botanical Garden.<br />

Presence <strong>of</strong> some ground orchid species in the said areas indicates the Forest types <strong>of</strong> the area. For example the<br />

presence <strong>of</strong> ground orchids like Cymbidium lancefolium indicates that the forest area is dominated by Castanopsis<br />

hyxtrix.<br />

Calanthe brevicornu Lindl : C. brevicornu in East Sikkim occurs at an altitude <strong>of</strong> 2200 – 2500m (Plate 10) <strong>and</strong> the<br />

host trees in this zone are mainly Castanopsis tribuloides, Machilus odoratissima <strong>and</strong> Ehretia wallichiana along with<br />

some bamboo, ferns <strong>and</strong> grasses species. Similarly the occurrence <strong>of</strong> Calanthe brevicornu in Rabdentse Monastery<br />

area in West Sikkim at the same altitude have about 80% <strong>of</strong> similar types <strong>of</strong> trees <strong>and</strong> herb species combination as that<br />

<strong>of</strong> E. Sikkim.<br />

The alpine l<strong>and</strong>scape in the Himalaya is lined up as an archipelago on high mountains at the southern periphery <strong>of</strong> the<br />

high central Asia, separated from each other by deeply incised transverse valleys (Miehe 1997). Spread on either side<br />

<strong>of</strong> the Greater Himalaya or Himadri, this zone exhibits exceptional ecological, geohydrological, aesthetic <strong>and</strong> biological<br />

values. This zone is demarcated by a distinct treeline towards lower elevation that lies around 3300+200 m above msl<br />

in the western <strong>and</strong> 3800+200 m in the eastern Himalaya. The area immediately above natural treeline is usually<br />

occupied by a range <strong>of</strong> vegetation formations such as Krummholz (= stunted forest or crooked wood, German), matted<br />

str<strong>and</strong>s <strong>of</strong> shrubs, herbaceous meadows, bogs, <strong>and</strong> fell-fields paved with mosses <strong>and</strong> lichens.<br />

The alpine region in Sikkim <strong>and</strong> other parts <strong>of</strong> eastern Himalaya differs considerably from that <strong>of</strong> western Himalaya in<br />

terms <strong>of</strong> extent, terrain, climate, plant community composition, primary productivity, faunal assemblages <strong>and</strong> history <strong>of</strong><br />

human use. This zone becomes rather limited in extent <strong>and</strong> fragmented from west to east. The eastern Himalaya has<br />

a prolonged monsoon season from June to September <strong>and</strong> little precipitation is received from western disturbances in<br />

winter. The western Himalaya, on the other h<strong>and</strong>, has a short monsoon from July to August <strong>and</strong> a fairly long wet season<br />

from November to April. The eastern Himalaya is more tropical in latitude <strong>and</strong> is geographically closer to the Bay <strong>of</strong><br />

Bengal <strong>and</strong> heavily influenced by the monsoon winds. Consequently, it has an oceanic climate with higher humidity<br />

<strong>and</strong> exhibits higher seasonal primary productivity. The tree line is higher at 4000 m <strong>and</strong> the permanent snow line at<br />

5500 m. The krummholz <strong>and</strong> alpine scrub zone is also more extensive. It has a relatively recent history <strong>of</strong> extensive<br />

grazing <strong>and</strong> pristine areas with an insignificant history <strong>of</strong> grazing still exist. The recent geological origin, limited extent<br />

<strong>and</strong> fragmentation, steeper terrain <strong>and</strong> higher rainfall make them more fragile as compared to the western Himalaya.<br />

The Khangchendzonga NP is located on the western flank <strong>of</strong> Sikkim (<strong>India</strong>) between 27 o 30' to 27 o 55' N latitude <strong>and</strong><br />

88 o 02' <strong>and</strong> 88 o 37' E longitude <strong>and</strong> spreads over 1784 km 2 adjacent to Nepal. The park is named after Mt.<br />

Khangchendzonga (8586 m), the third highest peak in the world. The park covers nearly 25% <strong>of</strong> the geographical area<br />

<strong>of</strong> the state (Sikkim). The climate <strong>of</strong> KNP is characterized by a long monsoon followed by a long winter. The annual<br />

rainfall varies from more than 300 cm in the southern part to less than 150 cm in the north <strong>and</strong> altitude ranges from ca.<br />

1220 m to 8586 m. As per the classification by Champion & Seth (1968), as many as 18 distinct types <strong>and</strong> sub-types are<br />

discernible within KNP. Floristic study by Maity <strong>and</strong> Maiti (2007) indicates that the KNP <strong>and</strong> surrounding buffer forests<br />

harbour about 1580 species <strong>of</strong> vascular plants which include 106 species <strong>of</strong> Pteridophytes, 11 Gymnosperms <strong>and</strong><br />

1463 Angiosperms. The alpine zone as used in this article includes the areas between 4000 <strong>and</strong> 5000 m elevation.<br />

Physiognomically it starts from where the Krummholz thickets end <strong>and</strong> the alpine scrub begins <strong>and</strong> extends up to the<br />

subnival vegetation. About 22% <strong>of</strong> the park with an extent <strong>of</strong> 390 km 2 falls within this zone.<br />

Vegetation Structure <strong>and</strong> Composition<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

The alpine meadows <strong>of</strong> KNP are dominated by sedges namely Kobresia nepalensis (on smooth slopes), Kobresia<br />

duthiei (on broken slopes) <strong>and</strong> Kobresia pygmaea <strong>and</strong> Kobresia schoenoides (in dry meadows). Grassy meadows <strong>of</strong><br />

Danthonia cachemyriana <strong>and</strong> tall forb communities in deep soil are more characteristic <strong>of</strong> the western Himalaya <strong>and</strong><br />

were virtually absent in KNP (Rawat 2005). The major grass-dominated vegetation in the KNP is the Deschampsia<br />

caespitosa marsh meadow found only in the fringes <strong>of</strong> glacial lakes <strong>and</strong> streams. The subalpine thickets <strong>of</strong> Rhododendron<br />

<strong>and</strong> alpine scrub vegetation <strong>of</strong> Rhododendron, Cassiope <strong>and</strong> Juniperus is much more extensive in the Sikkim Himalaya.<br />

Based on numerical classification the vegetation <strong>of</strong> the alpine zone was segregated into 11 types namely, krummholz<br />

thicket, Juniper scrub, Rhododendron scrub, morainic scrub, Salix sikkimensis riverine thicket, Myricaria rosea riverine<br />

scrub, Kobresia nepalensis moist meadow, Kobresia duthiei moist meadow, Kobresia pygmaea moist meadow,<br />

Deschampsia caespitosa marsh meadow <strong>and</strong> Anaphalis xylorhiza dry meadow (Plates 11 A & 11B). Brief description <strong>of</strong><br />

the special habitats is as follows:<br />

(i) Krummholz thickets : Extensive Krummholz thickets are found between 3600 to 4200 m. This category extends<br />

upwards from the tree line <strong>and</strong> gradually becomes stunted with elevation before giving way to the alpine scrub<br />

communities. They favour shady <strong>and</strong> moist localities <strong>and</strong> are most luxuriant in the north <strong>and</strong> northwest aspects<br />

especially on rocky slopes. The vegetation formation is dense, thicket forming <strong>and</strong> impenetrable with the canopy<br />

height generally varying between one to four meters mostly dominated by various species <strong>of</strong> Rhododendron. The<br />

following associations are easily identifiable viz., Rhododendron campanulatum, R. lanatum, R. thomsonii <strong>and</strong> R.<br />

wightii – R. fulgens. The floor is thickly carpeted with mosses <strong>and</strong> fallen leaves <strong>and</strong> the ground flora is generally sparse<br />

(Plate 11A).<br />

(ii) Alpine scrub : Dwarf Rhododendron scrub is widespread in the higher reaches above the Krummholz zone. This<br />

category (less than 1 meter tall) represents alpine moist scrub <strong>and</strong> favours the north - northeastern aspects between<br />

3900 to 4600 m. This vegetation is very dense <strong>and</strong> the Ericaceous cover is more than 50% with very few gaps or<br />

openings. The shrub layer is co-dominated by three species <strong>of</strong> Rhododendron, viz., R. anthopogon (sun-pate), R.<br />

setosum <strong>and</strong> R. lepidotum. Juniper scrub is found generally between 3700 to 4400 m on warmer slopes i.e, south <strong>and</strong><br />

southwest aspect. The characteristic species are Juniperus recurva <strong>and</strong> J. indica. The former is prostate in habit <strong>and</strong><br />

found more commonly between 3700 - 4100 m, while the latter usually occurs in the form <strong>of</strong> erect shrub between 4000<br />

to 4400 m. In the inner dry valleys this Juniper ascends up to 4800 m.<br />

(iii) Kobresia nepalensis moist meadow is the most widespread <strong>and</strong> dominant vegetation in altitudes ranging from<br />

4000 to 5100 m in the alpine zone. It occurs most luxuriantly on the smooth slopes <strong>and</strong> ridge tops in the upper reaches<br />

<strong>of</strong> moist, exposed, glaciated valleys. This dense s<strong>of</strong>t mat like formation has an average height <strong>of</strong> 0.1 m. The cover <strong>of</strong><br />

Kobresia nepalensis (sun buki) varies a lot with micro-topography <strong>and</strong> co-dominates with Bistorta milletii, Potentilla<br />

peduncularis, Rhododendron lepidotum, Primula capitata <strong>and</strong> species <strong>of</strong> Arenaria, Juncus <strong>and</strong> Carex. Openings in<br />

rich soils are colonized by Potentilla peduncularis, around cattle camps by Ranunculus hirtellus (khorsane) <strong>and</strong><br />

compacted soils by Bistorta sp., Picrorhiza scrophulariiflora (kurki), Lomatogonium spp. (Vern. Sharmaguru <strong>and</strong><br />

Mahaguru) are the valuable ethno-medicinal plans found in this vegetation. This is the most extensive <strong>and</strong> nutrient rich<br />

vegetation that sustains livestock <strong>and</strong> wild ungulate populations in the KNP.<br />

(iv) Kobresia duthiei moist meadow found in pockets prefers moist valleys on slopes that are bouldery <strong>and</strong> steep in<br />

the 4000 to 4600 m elevation zone. The vegetation is tussock forming dominated by Kobresia duthiei (cover greater


than 40%) with an average height <strong>of</strong> 0.30 m. In openings K. nepalensis, Kobresia capillifolia, Rheum acuminatum,<br />

Rhododendron anthopogon, Geranium donianum <strong>and</strong> species <strong>of</strong> Heracleum, Swertia sp. <strong>and</strong> Pleurospermum <strong>and</strong><br />

Juncus are usually found. Good population <strong>of</strong> valuable medicinal plants like Aconitum ferox, Nardostachys gr<strong>and</strong>iflora,<br />

Bergenia purpurascens can be seen at such sites.<br />

(v) Kobresia pygmaea moist meadow is found in the upper reaches <strong>of</strong> the glaciated <strong>and</strong> relatively dry Zemu <strong>and</strong><br />

Lhonak valleys in the elevation range <strong>of</strong> 4400 to 5100 m. As the name suggests in the upper reaches this vegetation is<br />

stunted having average height <strong>of</strong> 0.05 m. In the lower reaches, especially along streams Kobresia schoenoides <strong>and</strong><br />

Bistorta vivipera <strong>and</strong> in the upper reaches Kobresia spp., Bistorta milletii, Potentilla fruiticosa <strong>and</strong> Aster falconeri codominate.<br />

(vi). Anaphalis xylorhiza dry meadows are found in the trans-Himalayan glaciated valley flats usually between 4500<br />

to 5100 m. This Tibetan steppe like vegetation grows in dry, arid conditions <strong>and</strong> is characterized by dwarf herbaceous<br />

formations (average height is 0.1 m). The total vegetation cover is not more than 40%. Anaphalis xylorhiza is the<br />

dominant species (cover greater than 20%) with other associates such as Bistorta vivipera, Kobresia schoenoides,<br />

Kobresia nepalensis, Lancea tibetica <strong>and</strong> various species <strong>of</strong> Arenaria <strong>and</strong> Pedicularis. Other species include Aster<br />

diplostephiodes, Delphinium caeruleum, Cyananthus incanuns, Cortiella sp., Scabiosa sp., Gentiana stipitata, Lonicera<br />

rupicola, Elymus nutans <strong>and</strong> species <strong>of</strong> Rhodiola <strong>and</strong> Oxytropis.<br />

Floristic Structure <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong><br />

The Alpine L<strong>and</strong>scape in Western Sikkim:<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong><br />

Based on extensive floristic surveys conducted during 2004 - 2007, we have recorded a total <strong>of</strong> 585 species <strong>of</strong><br />

angiosperms within the alpine zone <strong>of</strong> KNP. These belong to 67 families <strong>and</strong> 243 genera. The dominant families are<br />

Asteraceae (69 species), Ranunculaceae (35 species), Poaceae (32 species), Scrophulariaceae (30 species),<br />

Cyperaceae (28 species) <strong>and</strong> Rosaceae (28 species). The prominent genera are Pedicularis (21 species), Carex (18<br />

species), Saxifraga (18 species) <strong>and</strong> Rhododendron (17 species). The gymnosperms in the subalpine <strong>and</strong> alpine<br />

zones include Taxus baccata subspecies wallichiana, Tsuga dumosa, Abies densa, Juniperus indica, Juniperus recurva<br />

<strong>and</strong> Ephedra gerardiana. The KNP along with the adjacent reserve forests is home to as many as 22 endemic <strong>and</strong> 22<br />

rare <strong>and</strong> threatened plants. Species <strong>of</strong> high conservation value <strong>and</strong> botanical interest in sub-alpine <strong>and</strong> alpine areas<br />

include Schiz<strong>and</strong>ra gr<strong>and</strong>iflora (a primitive climber with flowers like miniature Magnolia), Helwingia himalaica (bearing<br />

flowers at the center <strong>of</strong> the leaf <strong>and</strong> endemic to the Eastern Himalaya), Circaeaster agrestis (Chloranthaceae <strong>of</strong><br />

uncertain affinity), Pinguicula alpina (an insectivorous plant), Triosteum himalayanum (endemic to Himalaya),<br />

Brachycaulos simplicifolius (an unusual herb <strong>of</strong> Rosaceae) among others. Few more alpine plants needing special<br />

mention for their high conservation significance are the wild poppies (Meconopsis sp.) which bear spectacular flowers<br />

<strong>and</strong> have several medicinal properties, species <strong>of</strong> Corydalis, Rhodiola, Pleurospermum, Saussurea, Primula, Gentiana,<br />

Swertia, Pedicularis, Polygonatum <strong>and</strong> several ground orchids. Among the rhubarb species Rheum nobile is particularly<br />

vulnerable owing to its striking inflorescence which is <strong>of</strong>ten plucked by the herders <strong>and</strong> local communities to make<br />

pickle.<br />

Key floral species for conservation are Rheum nobile (Kenjo), Gymnadenia orchidis (panch amle), Nardostachys<br />

gr<strong>and</strong>iflora (jatamansi), Ephedra gerardiana, Picrorhiza scrophulariiflora (kurki), Aconitum ferox (Bikh), Saussurea<br />

obvallata, wild Alliums, Giant Lily (Cardiocrinum giganteum), Pseudo-ginseng (Panax pseudo-ginseng), Pleurospermum<br />

sp. <strong>and</strong> Caterpillar-mushroom (Cordyceps sinensis). Status <strong>of</strong> a few species is given below :<br />

Impacts <strong>of</strong> Anthropogenic Activities<br />

Pastoralism, collection <strong>of</strong> medicinal <strong>and</strong> aromatic plants <strong>and</strong> subsistence hunting were the main livelihoods prevalent<br />

in the KNP traditionally, while trekking tourism has exp<strong>and</strong>ed rapidly since early 1990s. Major impacts <strong>of</strong> anthropogenic<br />

activities on alpine vegetation are discussed below:<br />

i. Impacts <strong>of</strong> Pastoral Practices : In the KNP the livestock biomass increased from 608 metric tonnes in 1950 to 763<br />

metric tonnes in 2004 owing to a substantial rise in the populations <strong>of</strong> yak <strong>and</strong> cow-yak crossbreeds. The livestock<br />

impact units in the winter pastures increased more than 8 times from 2 to 17 Livestock Unit days ha -1 during this period.<br />

The main impacts <strong>of</strong> pastoralism on the natural environment are clearing <strong>and</strong> burning <strong>of</strong> forests, localized extraction<br />

<strong>of</strong> slow growing Juniper <strong>and</strong> Rhododendron firewood <strong>and</strong> a decline in the population <strong>of</strong> grazing sensitive plants. The<br />

herders carried out habitat manipulation by converting vegetation types like Juniper scrub in the alpine zone <strong>and</strong> the<br />

oak, hemlock <strong>and</strong> fir forests in the temperate <strong>and</strong> sub alpine zones into artificial pastures. <strong>Plants</strong> sensitive to yak grazing<br />

found in pastures not grazed by them are Heracleum sp. (ganer), Allium pratti (d<strong>and</strong>u), Kobresia duthiei (bhalu buki),<br />

Pleurospermum spp. (seto cheeru <strong>and</strong> shyamphul), Saussurea obvallata (brahma kamal) <strong>and</strong> Saussurea uniflora<br />

(thulo dudhe jhaar). These plants are annual or biannual, tall <strong>and</strong> regarded as nutrient rich by the herders.<br />

ii. Impacts <strong>of</strong> Medicinal <strong>and</strong> Aromatic Plant Collection : Alpine medicinal plants mostly Aconitum ferox (bikh) <strong>and</strong><br />

Picrorhiza scrophulariiflora (kurki) were in high dem<strong>and</strong> <strong>and</strong> were collected from 1970s to 1990s in truckloads with<br />

dried tubers <strong>of</strong> Bikh fetching USD 0.33 kg -1 <strong>and</strong> dried stems <strong>of</strong> Kurki fetching USD 0.44 kg -1 . The state government<br />

banned the commercial collection <strong>of</strong> medicinal plants for ten years from 2001 onwards. Aromatic plants Juniperus<br />

recurva (sikpa) <strong>and</strong> Juniperus indica (bhairung) were in high dem<strong>and</strong> for incense making <strong>and</strong> large scale commercial<br />

collection was done by the yak <strong>and</strong> dzo herders between 1970s <strong>and</strong> 1990s. Dried Juniperus recurva used to fetch USD

0.033 kg -1 while dried Juniperus indica USD 0.056 kg -1 in the local market <strong>and</strong> were collected in truckloads. At present<br />

no apparent impact <strong>of</strong> past collection was noticeable except very low populations <strong>of</strong> the high value species in southwestern<br />

parts <strong>of</strong> KNP. The abundance <strong>of</strong> these plants is relatively better in Zemu valley, which has remained relatively<br />

untouched in terms <strong>of</strong> commercial exploitation <strong>of</strong> plants.<br />

Conservation Action : In Sikkim a determined political leadership along with strong support from the local people is<br />

initiating conservation action to reduce the yak (<strong>and</strong> their hybrid) numbers in the greater Himalayan part <strong>of</strong> KNP while<br />

also providing alternative livelihood support to the herders from ecotourism enterprise. Consequently over the last few<br />

years the livestock population in the KNP has reduced significantly. Commercial harvest <strong>and</strong> transit <strong>of</strong> medicinal <strong>and</strong><br />

aromatic plants has been banned from the forest areas <strong>of</strong> the State since 1990 owing to degradation <strong>of</strong> habitat <strong>and</strong><br />

rapid depletion <strong>of</strong> this valuable resource.<br />

The l<strong>and</strong> <strong>of</strong> the rising sun, Arunachal Pradesh or the NEFA (North-East Frontier Agency) <strong>of</strong> yester years is situated in the<br />

extreme north-eastern corner <strong>of</strong> <strong>India</strong>. It covers an area <strong>of</strong> 83740 km2 <strong>and</strong> lies between 26° 28' to 29° 30' North latitudes<br />

<strong>and</strong> 90° 30' to 97° 30' East longitudes. It is bounded by Mc-Mohan Line in the north that separates <strong>India</strong> from Tibet<br />

(China), by Myanmar (Burma) in the east, the states <strong>of</strong> Nagal<strong>and</strong> <strong>and</strong> Assam in the south <strong>and</strong> by Bhutan in the west.<br />

Administratively, the state is divided into 15 districts which represent more or less distinct water-sheds or ethnographic<br />

sub-regions, invariably named after a river. The state is well known for its diverse ethnic groups, inhabiting various<br />

regions, each with its distinct culture <strong>and</strong> dialect. Traditionally, the state is divided into 5 ethnographic regions (based<br />

on the predominance <strong>of</strong> native communities): i. Aka hills, ii. Daphla hills, iii. Miri hills, iv. Abor hills <strong>and</strong> v. Mishmi hills.<br />

Biogeographically, Arunachal Pradesh forms major part <strong>of</strong> Eastern Himalaya (2C), the richest biogeographic province<br />

in <strong>India</strong>. The entire territory forms a complex system <strong>of</strong> hills with varying elevation ranging from 50m asl adjacent to<br />

Assam plains to about 7750m in the Great Himalayan range. The hill ranges are extremely rugged, dissected by deep<br />

river valleys <strong>and</strong> streams which run more or less in north-south direction. The rainfall spreads over 8-9 months except<br />

during winter season <strong>and</strong> it varies from 2,000 mm in the higher reaches to 8,000 mm in the foot hills. There are six<br />

major rivers flowing through the state, viz., Kameng, Subansiri, Siang, Lohit, Tirap <strong>and</strong> Dibang. These rivers <strong>and</strong> their<br />

tributaries form distinct catchments culminating at snow peaks towards higher reaches <strong>and</strong> finally drain into<br />

Brahmaputra. There are six principal rivers in the state namely: Kameng, Subansiri, Siang, Lohit, Tirap <strong>and</strong> Dibang.<br />

Physiographically the state can be divided into three zones from south to north as follows:<br />

i. The Alluvial Plains : This is a narrow division running parallel to foot-hills along the southern border <strong>of</strong> Arunachal<br />

Pradesh <strong>and</strong> includes the longitudinal alluvial plains Kameng, Subansiri, Siang, Dibang <strong>and</strong> Lohit. The area has<br />

a more or less flat topography that gradually merges with the plains <strong>of</strong> Assam in the northern part <strong>of</strong> Brahmaputra<br />

valley.<br />

ii. The Lesser Himalaya: Rising abruptly from the foot hills, this region is interspersed by heavily dissected Shiwalik<br />

formations <strong>and</strong> sedimentary rocks <strong>of</strong> Lesser Himalaya. The highest altitude <strong>of</strong> this zone is about 1000m.<br />

iii. The Greater Himalaya: It is the dominant division <strong>of</strong> the state, marked by the peaks reaching as high as 6000m <strong>and</strong><br />

more. Some <strong>of</strong> the known peaks <strong>of</strong> this division are: Gorichen (7300m), Kangto (7090m), Namche Barwa (7756m)<br />

<strong>and</strong> Kulangri (7544m).<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

The diversity <strong>of</strong> topographical features <strong>and</strong> climatic conditions has favoured the growth <strong>of</strong> luxuriant forests, which cover<br />

about 61.55% <strong>of</strong> the total geographic area. The forest vegetation comprises some <strong>of</strong> the tallest trees, tree ferns,<br />

bamboos, a large number <strong>of</strong> orchids, rhododendrons, several botanical curios, rare, endemic, primitive flowering<br />

plants <strong>and</strong> a store house <strong>of</strong> a large number <strong>of</strong> economically important species. Such an unparallelled occurrence <strong>of</strong><br />

life forms can be attributed to the peculiar location <strong>of</strong> the state which is at the junction <strong>of</strong> the Paleoarctic, Indo-Chinese,<br />

<strong>and</strong> Indo-Malayan biogeographic regions. The biotic elements from all these regions occur in this state making its<br />

biological diversity extremely rich.<br />

The characteristic three storeyed sequence <strong>of</strong> vegetation particularly in the tropical <strong>and</strong> subtropical zones is one <strong>of</strong> the<br />

significant features in Arunachal Pradesh where the shrubs <strong>and</strong> small trees form the ground storey, the medium sized<br />

trees form the middle storey <strong>and</strong> the l<strong>of</strong>ty trees with dense canopy form the top storey. The vegetation <strong>of</strong> Arunachal<br />

Pradesh can be divided into following categories:<br />

(A) Tropical Forests: Based on the composition <strong>and</strong> structure this can be further divided into two subtypes viz., Tropical<br />

Evergreen, <strong>and</strong> Tropical Semi-evergreen. The former typically extends from foothills up to 1000m in the areas receiving<br />

maximum rainfall. Species <strong>of</strong> Altingia, Amoora, Artocarpus, Terminalia, Canarium, Castanopsis, Dysoxylum,<br />

Cinnamomum, Quercus, Magnolia, Mesua, Duabanga, Lagerstroemia, Ptereospermum, Dillenia, Bisch<strong>of</strong>ia <strong>and</strong> Gmelina<br />

are some <strong>of</strong> the common trees <strong>of</strong> this type. The top canopy or the upper storey in these forests cover stifle plants <strong>of</strong> the<br />

lower storeys providing ideal conditions for the pr<strong>of</strong>use growth <strong>of</strong> understorey vegetation as well as epiphytes including<br />

orchids, ferns <strong>and</strong> a variety <strong>of</strong> climbers.<br />

(B) Subtropical Forests: These forests, basically evergreen in nature <strong>and</strong> having continuous dense canopy, occur<br />

mainly between 900-2000m. The trees attain large dimensions i.e., 25-40m in height. These forests are dominated by<br />

species <strong>of</strong> Acer, Alnus, Beilschmiedia, Litsea, Kydia, Quercus <strong>and</strong> Magnolia <strong>and</strong> harbour pr<strong>of</strong>use growth <strong>of</strong> epiphytic<br />

orchids, ferns <strong>and</strong> climbers. The humus rich forest floors are occupied with dense <strong>and</strong> diverse ground flora consisting<br />

<strong>of</strong> a large number <strong>of</strong> herbaceous species <strong>and</strong> terrestrial orchids.<br />

(C) Pine Forests: These forests extend both in subtropical <strong>and</strong> temperate belt in between 1000 m to 1800m elevation.<br />

Generally occupying the smaller rain shadow areas, these forests are represented by three species <strong>of</strong> Pinus, viz., P.<br />

roxburghii, P. wallichiana <strong>and</strong> P. merkusii occasionally mixed with species <strong>of</strong> Alnus, Betula, Rhododendron, Quercus,<br />

Lyonia, Tsuga <strong>and</strong> Prunus. The ground flora is less diverse compared to other categories <strong>and</strong> do not support luxuriant<br />

growth <strong>of</strong> vascular <strong>and</strong> non-vascular epiphytes.<br />

(D) Moist Temperate Forests : These forests occur in all districts as a continuous belt between 1800-3500 m altitude<br />

<strong>and</strong> can be divided into two subtypes, viz., Temperate broad leaved <strong>and</strong> Temperate Conifer forests. The former extend<br />

from 1800 to 2800m. Quercus-Michelia-Acer, Castanopsis-Acer-Magnolia, Magnolia-Quercus- Exbuckl<strong>and</strong>ia <strong>and</strong><br />

Rhododendron- Quercus- Magnolia are some <strong>of</strong> the common associations found in these forests. The epiphytic flora<br />

is dominated by a number <strong>of</strong> species <strong>of</strong> orchids, Rhododendrons, ferns <strong>and</strong> fern allies. The ground flora abounds in<br />

terrestrial species <strong>of</strong> orchids <strong>and</strong> other herbaceous elements. The Temperate conifer forests are found between 2800<br />

to 3500m elevation except in Tale valley. These areas experience heavy snowfall during winter. The domoinent<br />

species <strong>of</strong> this zone are Abies, Taxus, Picea, Larix, Juniperus mixed with species <strong>of</strong> Pinus, Acer, Rhododendron,<br />

Viburnum, Gaultheria, Berberis with gregarious undergrowth <strong>of</strong> temperate bamboo at places <strong>and</strong> terrestrial orchids.


(E) Subalpine <strong>and</strong> Alpine Forests : There is no sharp division between subalpine <strong>and</strong> alpine type <strong>and</strong> only a rough<br />

distinction can be made with concentration <strong>of</strong> certain elements. The zone between 3500-4000 m is termed as the<br />

subalpine zone characterized by tree species like Abies spectabilis, Cupressus corneyana, Juniperus recurva, Larix<br />

griffithiana, Pinus wallichiana, Rhododendron spp., Taxus wallichiana <strong>and</strong> Tsuga dumosa. The common shrubs are<br />

Berberis asiatica, B. wallichiana, Eurya acuminata, Gaultheria fragrantissima, Photinia integrifolia <strong>and</strong> species <strong>of</strong><br />

Vaccinium. Towards higher altitude a few terrestrial orchids <strong>and</strong> other small alpine herbs like Aconitum, Primula,<br />

Saussurea, Gentiana, Polygonum, Rhodiola, Sedum, Saxifraga dominate the ground vegetation.<br />

The alpine zone (4000 to 5500m asl), i.e. area above tree line remains covered with snow for the major part <strong>of</strong> the year.<br />

The vegetation is dominated by dwarf shrubs such as species <strong>of</strong> Rhododendron <strong>and</strong> herbaceous elements with<br />

attractive brilliantly coloured flowers. Various species <strong>of</strong> Aconitum, Arenaria, Gentiana, Meconopsis, Polygonum, Primula,<br />

Rhodiola, Saussurea, Saxifraga <strong>and</strong> Sedum abound in the alpine region.<br />

(F) Secondary Forests: Degraded forests as a result <strong>of</strong> anthropogenic pressures in the form <strong>of</strong> shifting cultivation,<br />

developmental activities <strong>and</strong> urbanization <strong>and</strong> forest fires lead to secondary scrub <strong>and</strong> open woodl<strong>and</strong>s. Such forests<br />

at the lower altitudes are characterized by the presence <strong>of</strong> species <strong>of</strong> Bauhinia, Callicarpa, Glochidion, Mallotus<br />

alongwith common shrubs like Capparis, Clerodendrum, Croton, Eurya, R<strong>and</strong>ia, Rubus, Viburnum species weeds like<br />

Ageratum, Eupatorium <strong>and</strong> Mikania. In temperate belt, subsequent to ‘Jhum’ cultivation species <strong>of</strong> bamboo, e.g.,<br />

Bambusa, Chimonobambusa, D<strong>and</strong>rocalamus, Schizostachyum take over. Open forests <strong>and</strong> areas with poor soil are<br />

dominated by various grasses e.g., species <strong>of</strong> Arundinella, Chrysopogon, Eragrostis, Imperata, Mnesithea, Paspalum,<br />

Saccharum, Setaria, Themeda <strong>and</strong> Thysanolaena.<br />

Floristic Diversity <strong>and</strong> <strong>Plants</strong> <strong>of</strong> High Conservation Significance<br />

Arunachal Pradesh –<br />

The Cradle <strong>of</strong> Flowering <strong>Plants</strong><br />

The state is home <strong>of</strong> myriad plant <strong>and</strong> animal species making it one <strong>of</strong> the important biodiversity hotspots in the world<br />

(Chowdhery et al., 1996, 2008; Chowdhery 1997). It harbours over 5000 species <strong>of</strong> flowering plants distributed across a<br />

wide range <strong>of</strong> habitats. These include a large number <strong>of</strong> economically important, interesting <strong>and</strong> biologically curious<br />

plants which are confined to this state. The early history <strong>of</strong> botanical explorations in the state can be seen in Burkill (1924<br />

– 25). Some <strong>of</strong> the angiosperm groups having high conservation significance (Plate 12) are briefly described below:<br />

(a) Wild Edible <strong>Plants</strong> : A large number <strong>of</strong> wild plants are consumed as vegetable, fruits, etc. these are collected from<br />

the forests by the locals <strong>and</strong> many <strong>of</strong> them are sold in the local markets also. Alternanthera philoxeroides (leafy<br />

vegetable), Baccaurea ramiflora (fruits), Begonia josephii (leafy vegetable), Calamus erectus (fruits), Castenopsis<br />

indica (seeds), Dioscorea bulbifera (tubers), Elaeagnus latifolia (fruits), Flemingia procumbens (tuberous roots),<br />

Houttuynia cordata (leafy vegetable), Impatiens longipe (leafy vegetable), Polygonum spp. (leafy vegetable), Rhus<br />

semialata (fruits), Viburnum spp. (fruits), etc. are some <strong>of</strong> the commonly used plants for food.<br />

(b) Wild Relatives <strong>of</strong> Cultivated <strong>Plants</strong>: Arunachal Pradesh falls under ‘Hindustan Centre <strong>of</strong> Origin <strong>of</strong> Cultivated plants’.<br />

Several species from which the present day cultivated plants were selected still continue to exist alongwith their close<br />

relatives. The genes from wild relatives may help plant breeders to breed crops that can resist pests <strong>and</strong> diseases <strong>and</strong><br />

thus are in utmost need more than ever before to feed the fast exp<strong>and</strong>ing world population. The state is rich in wild<br />

varieties <strong>of</strong> Musa, Citrus, Allium, Brassica, barley, maize, buckwheat, fingermillet, foxtail- millet, amaranth, french bean,<br />

soybean, cowpea, blackgram, pea, scarlet bean, pumkin, cucumber, ginger, chayote, tree tomato, pome <strong>and</strong> stone<br />

fruits. Apart from these, the state is equally rich in tall <strong>and</strong> drought-hardy types <strong>of</strong> Sesame, tree cotton, taros, yam <strong>and</strong><br />

species <strong>of</strong> Colocasia <strong>and</strong> Capsicum.<br />

(c) Species <strong>of</strong> Medico-ethnobotanical Importance: The north-eastem region especially Arunachal Pradesh is the home<br />

<strong>of</strong> a large number <strong>of</strong> tribal population having immense information on the use <strong>of</strong> natural resources acquired over<br />

centuaries through their experience. A large number <strong>of</strong> plants <strong>and</strong> animals are used by them in their day to day life for<br />

food, medicine, fish-poisoning, dye making, local drinks, etc. A wide range <strong>of</strong> medicinal plants are used by the local<br />

people for health care <strong>and</strong> a majority <strong>of</strong> them are used in the preparation <strong>of</strong> various Ayurvedic, Homoeopathic <strong>and</strong><br />

Unani medicines. In addition there are several species <strong>of</strong> other ethnobotanical value e.g., Acacia rugata (powdered<br />

stems are used in fish-poisoning); Amischotolype mollissima (plant juice is used as arrow-poison); Gallium mollugo<br />

(decoction is used in dying clothes); Anisomeles ovata (used to relief mascular pain); Berberis wallichana (bunch <strong>of</strong><br />

spines are used in tattooing chin <strong>and</strong> forehead); Bidens biternata (leaves are as substitute for tea); Callicarpa arborea<br />

var. ovalifolia (stems are used as bstitute <strong>of</strong> tobacco); Chenopodium album (seeds are used for preparation <strong>of</strong> country<br />

liquor’ Apong’); Chimonobambusa callosa (bark is used as rope);Chlrophytum arundinaceum (used as substitute <strong>of</strong><br />

onion); Crassocephalum crepidioides (leaf juice is used to prevent bleeding); Dendrobium hookerianum (flowers are<br />

used to prepare yellow dye); Dendrocalamus strictus (planted near the house in spiritual belief <strong>of</strong> keeping the devil spirit<br />

away); Elscholtzia bl<strong>and</strong>a (paste prepared from leaves is used to clear pus <strong>and</strong> maggot <strong>of</strong> cattle); Gaultheria<br />

fragrantissima (leaves <strong>and</strong> tmigs are used as incense); Gentiana bryoides (whole plant mixed with’ sillu’ leaves used<br />

as incense, leaves are used in malaria <strong>and</strong> dysentery); Geranium nepalense (the paste prepared from whole plant<br />

mixed with turmeric <strong>and</strong> mustard oil is used in cases <strong>of</strong> eczema, itch <strong>and</strong> other skin diseases); Gerbera piloselloides<br />

(used as hot fomentation to relief rheumatic pain); Impatiens racemosa (whole plant is used in malarial fever); Lasianthus<br />

longicauda (fruit extract is used as gum for catching birds); Plectranthus hispidus (whole plant is used in cough <strong>and</strong><br />

cold); Rubus paniculata (leaves are used as substitute for peper betel); Scrophularia elatior (decoction <strong>of</strong> whole plant<br />

is used in urinary trouble); Tacca integrifolia (decoction <strong>of</strong> leaves is used in blood dysentery <strong>and</strong> diarrhoea).<br />

(d) Botanical Curiosities: Several species <strong>of</strong> angiosperms represent unique evolutionary links <strong>and</strong> botanical curiosities.<br />

For example, Sapria himalayana -one <strong>of</strong> the largest root parasites first reported by Griffith from Mishmi hills in Lohit<br />

district, Rhopalocnemis phalloides in Namdapha in Changlang district, Balanophora dioica, Aeginetia indica <strong>and</strong><br />

Boschniakia himalaica, a parasite on the roots <strong>of</strong> Rhododendron spp. is found in the alpine meadows <strong>of</strong> the state.<br />

Among the common saprophytes, Monotropastrum humile <strong>and</strong> orchids such as Epipogium spp. <strong>and</strong> Galeola spp. are<br />

found in dense humid forests on humus rich soil. Among other curious plants mention may be made <strong>of</strong> Drosera peltata,<br />

an insectivorous plant <strong>and</strong> Zeylanidium olivaceum, a lichen like thallose herb which grows under water in fast running<br />

streams.<br />

(e) Endemic species: The state abounds in endemic plant species. Some <strong>of</strong> the important endemic taxa include Acer<br />

oblongum var. microcarpum, A. sikkimense var. serrulatum, Aconogonum pangianum, Begonia aborensis, B. scintillum,<br />

Capparis pachyphylla, Coptis teeta, Hedychium longipedunculaturn, Illicium cambodianum, Lysimachia congestiflora<br />

var. santapaui, Maesa arunachalensis, Merrilliopanax listeri, Paphiopedilum wardii, Pholidota watii, Primula subansirica,<br />

Pternopetalum senii, Pueraria bella, Rhododendron santapaui, Rhynchoglossum lazulinum, Schefflera venulosa,<br />

Tricarpelema gl<strong>and</strong>uliferum, <strong>and</strong> Wallichia tri<strong>and</strong>ra, etc.<br />

(f) Rare <strong>and</strong> Endangered <strong>Plants</strong>: Shifting cultivation, over exploitation <strong>of</strong> medicinal <strong>and</strong> other useful economic plants,<br />

rapid development <strong>of</strong> infra-structure such as new townships, roads, industries, clearing <strong>of</strong> forest l<strong>and</strong> for permanent<br />

agriculture have led to decline <strong>of</strong> many plant populations <strong>and</strong> degradation <strong>of</strong> their habitats. Some <strong>of</strong> the rare, endangered<br />

<strong>and</strong> vulnerable categories <strong>of</strong> plants are: Ardisia rhynchophylla, Aquilaria malaccensis, Cymbidium hookerianum,<br />

C.eburneum, Coptis teeta, Dioscorea laurifolia, D. orbiculata, Diplomeris hirsuta, Drosera peltata, Eria ferruginea,<br />

Galeola falconeri, Gastrochilus inconspicuus, Huodendron biaristatum, Ilex venulosa, Nomocharis synaptica,<br />

Rhododendron nuttalli, R. santapaui, Rhopalocnemis phalloides, Sapria himalayana, Saurauia griffithii, Sunipia fuscopurpurea,<br />

<strong>and</strong> Tylostyli discolor.

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

(g) Primitive Angiosperms : Presence <strong>of</strong> a large number <strong>of</strong> primitive Angiosperms in the state such as Altingia excelsa,<br />

Aspidocarya uvifera, Betula alnoides, Decaisnea insignis, Euptelea pleiosperma, Exbuckl<strong>and</strong>ia populnea,<br />

Haematocarpus validus, Holboellialatifolia var. angustifolia, Houttuynia cordata, Magnolia caveana, M. grifflthii, M.<br />

hodgsonii, M. pterocarpa, Pycnarrhena pleniflora, Tetracentron sinense <strong>and</strong> species <strong>of</strong> Camellia, Magnolia, Michelia,<br />

Rhododedron, orchids <strong>and</strong> several wild <strong>and</strong> economic plants suggest that perhaps in this region evolutionary<br />

development <strong>of</strong> Angiosperms have taken place. Takhtajan (1969) has suggested North Eastern Region <strong>of</strong> <strong>India</strong> as the<br />

true “Cradle <strong>of</strong> flowering plants” due to the presence <strong>of</strong> large number <strong>of</strong> primitive Angiosperms.<br />

The North-eastern region <strong>of</strong> <strong>India</strong> assumes a special significance in the biogeography <strong>of</strong> the country due to its unique<br />

location <strong>and</strong> varying eco-climatic conditions. It is located at the confluence <strong>of</strong> <strong>India</strong>n Peninsula, Indo-Malayan <strong>and</strong><br />

Indo-Chinese biogeographical zones (Rao 1994). It is regarded as one <strong>of</strong> the 25 biodiversity hotspots in the world<br />

(Myers 1988). The undulating topography, high rainfall <strong>and</strong> varied altitudes are main factors that have contributed to its<br />

rich ecosystem <strong>and</strong> habitat diversity. The region represents about 50% <strong>of</strong> the floristic wealth <strong>of</strong> <strong>India</strong> <strong>and</strong> contains about<br />

8000 species <strong>of</strong> flowering plants including several representatives <strong>of</strong> primitive or ancient angiosperms (Takhtajan<br />

1969). It abounds in gene pool <strong>of</strong> cultivars <strong>and</strong> l<strong>and</strong> races <strong>of</strong> crop plants. So far, about 64 species <strong>of</strong> Citrus have been<br />

recorded from this region, <strong>of</strong> which, Citrus assamensis, Citrus indica <strong>and</strong> Citrus latipes are confined within Nokrek<br />

National Park <strong>of</strong> Meghalaya suggesting a strong indication that North-eastern region has been the centre <strong>of</strong> origin for<br />

Citrus (Singh 1984). However, this biodiversity is dwindling at an alarming rate due to high population pressure <strong>and</strong><br />

ruthless exploitation <strong>of</strong> the forest resources. Consequently, more than 700 taxa <strong>of</strong> plants have been pushed to various<br />

categories <strong>of</strong> threat in this region (Nayar & Sastry 1988 - 90).<br />

The state <strong>of</strong> Meghalaya is characterized by a wide range <strong>of</strong> physiographic, edaphic <strong>and</strong> climatic conditions making it<br />

a congenial area for luxuriant growth <strong>of</strong> vegetation. The recorded forest cover <strong>of</strong> the state is 9,496 km2 (42.34 % <strong>of</strong> the<br />

total geographic area). More than eight different forest types ranging from tropical to temperate categories, a large<br />

number <strong>of</strong> primitive species (Haridasan & Rao 1985-87) <strong>and</strong> high level <strong>of</strong> endemism (1236 species i.e. 37.11% <strong>of</strong> total<br />

plant species including ferns <strong>and</strong> bryophytes) make this state extremely important for plant conservation point <strong>of</strong> view<br />

(Khan et al. 1997). The three ethnographic zones <strong>of</strong> the state viz., the Khasi, Jaintia <strong>and</strong> Garo Hills have long been focal<br />

points <strong>of</strong> botanical exploration. According to Champion & Seth (1968), Assam Sub-tropical Hill Savanna, Khasi Subtropical<br />

Hill Forests, Assam Sub-tropical Pine Forests <strong>and</strong> Assam Sub-tropical Pine Savannah are the major forest<br />

types in the state <strong>of</strong> Meghalaya. Haridasan & Rao (1985-87) recognized following major categories <strong>of</strong> vegetation in<br />

Meghalaya: Tropical Evergreen Forests in low-lying, high rainfall areas; Tropical Semi-Evergreen Forests (up to<br />

elevation <strong>of</strong> 1200m, where annual rainfall is 1500-2000mm); Tropical Moist Deciduous Forests in areas with less than<br />

1500 mm rainfall; grassl<strong>and</strong>s <strong>and</strong> savanna on the tops <strong>of</strong> Khasi, Jaintia <strong>and</strong> Garo Hills. Isolated patches <strong>of</strong> temperate<br />

forests are found at higher altitudes in Khasi <strong>and</strong> Jaintia hills. Sub-tropical Pine Forests are also found at higher<br />

altitudes in such areas where the original broad-leaved forests were felled or disturbed otherwise.<br />

The major anthropogenic activities such as shifting cultivation, infra-structure development <strong>and</strong> mining have led to<br />

decrease in forest cover, habitat fragmentation <strong>and</strong> loss <strong>of</strong> biodiversity. This article deals with some <strong>of</strong> the important<br />

vegetation types (broad habitats, sensu lato) <strong>and</strong> corresponding plant species peculiar to such areas.<br />

Major Habitat / Vegetation Types :<br />

84<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

1. Tropical Evergreen forests : This forest type spreads over the lower reaches <strong>of</strong> Khasi <strong>and</strong> Garo hills, up to 1200m.<br />

The dominant tree species include Castanopsis indica, Callophyllum polyanthum, Dysoxylum gobara, Elaeocarpus<br />

rugosus, Engelhardtia spicata, Gynocardia odorata <strong>and</strong> Helicia robusta, which are densely interwoven by lianas <strong>and</strong> a<br />

few emergents. The shrub species are Dendrocnide sinuata, Lasianthus hookerii, Rhynchotechum ellipticum, Boehmeria<br />

platyphylla, Leea crispa <strong>and</strong> Allophyllus distachys. During monsoon season members <strong>of</strong> Acanthaceae are quite<br />

abundant. The ground vegetation is dominated by Impatiens spp., Polygonum spp., Ophiorrhiza sp., Globba clarkei,<br />

Hedychium spp., <strong>and</strong> Costus specious among others. The forest floors are laden with a variety <strong>of</strong> ferns. The tree trunks<br />

<strong>and</strong> branches are covered with pr<strong>of</strong>use growth <strong>of</strong> mosses, ferns, orchids <strong>and</strong> other epiphytes. Lianas <strong>and</strong> climbers like<br />

Rhaphidophora spp. are also abundant.<br />

2. Semievergreen forests : These forests constitute the major natural habitat type <strong>of</strong> the state (IIRS 2003) <strong>and</strong> occupy<br />

the north-eastern <strong>and</strong> northern slopes with lesser rain-fall. The deciduous elements such as Albizzia spp., Callicarpa<br />

arborea, Careya arborea, Dillenia pentagyna, Parkia roxburghii, Rhus javanica <strong>and</strong> Shorea robusta are common.<br />

Other dominant species are Elaeocarpus floribundus, Micromelum integerrium, Garcinia spp., Sapindus rarak <strong>and</strong><br />

Symplocos paniculatus. The forest floor has luxuriant growith <strong>of</strong> several shade loving species such as Boehmeria<br />

sidifolia along with members <strong>of</strong> Acanthaceae, Rubiaceae <strong>and</strong> Zingiberaceae.<br />

3. Moist Deciduous forests : These forests are found in areas <strong>of</strong> lower rainfall (


compressus along with the members <strong>of</strong> Cyperaceae, (e.g., Fymbristylis dichotoma, Cyperus spp.) <strong>and</strong> Eriocaulaceae.<br />

Moist hill slopes have dense growth <strong>of</strong> Gualtheria fragrantissima, Eurya spp., Polygonum spp., Osbeckia stellata,<br />

Drosera peltata, Utricularia stiatula <strong>and</strong> U. bifida.<br />

8. Sacred groves : The age old traditions <strong>of</strong> all three tribes <strong>of</strong> Meghalaya, namely the Khasis, Jaintias <strong>and</strong> the Garos,<br />

have saved the patches <strong>of</strong> forests in prestine conditions till date. These secred groves chiefly fall in the subtropical zone<br />

represent the tropical broad-leaved hill forests (as described by Champion & Seth 1968) <strong>of</strong> the region. These groves<br />

harbour a plant wealth uncomparable with any other forest types <strong>of</strong> the region. Many <strong>of</strong> the endangered species are<br />

presently confined to the sacred groves. Members <strong>of</strong> Fagaceae family, Rhododendron arboreum <strong>and</strong> Elaeocarpus<br />

spp. dominate the vegetation. The trees show typically stunted growth. Epiphytes are found completely covering the<br />

tree trunks which support a number <strong>of</strong> epiphytic orchids <strong>and</strong> ferns (Plate 13A).<br />

basically a Himalayan element <strong>and</strong> its occurrence at lower altitude (up to 15 m asl) in the state calls for further genetic<br />

studies <strong>and</strong> it is vulnerable on account <strong>of</strong> its high value drug ‘Taxol’.<br />

Conservation<br />

Although there are two National Parks, three Wildlife Sanctuaries <strong>and</strong> more than twenty-five reserved forests established<br />

to safeguard the floral <strong>and</strong> faunal diversity <strong>of</strong> the state, most <strong>of</strong> the threatened species occur outside the existing<br />

network <strong>of</strong> protected areas. In addition, there are a number <strong>of</strong> forest patches which are conserved by the local communities<br />

on the religious <strong>and</strong> cultural ground. The reserved <strong>and</strong> community forests altogether, constitute only about 5% <strong>of</strong> the<br />

state, while the protected areas cover

An Interesting Species <strong>of</strong> Pteris<br />

from Mizoram<br />

During a recent floristic survey in Tawi Wildlife Sanctuary, Mizoram (18 th January 2007), we collected an interesting fern<br />

from dense forests. On critical examination this species turned out to be Pteris tricolor. After a detailed scrutiny <strong>of</strong><br />

literature it was revealed that this species has never been collected from the state so far. The specimen (collection no:<br />

40630) was later confirmed by Chris Fraser – Jenkins, Kathm<strong>and</strong>u. This is the first collection from Mizoram. The<br />

species grows as an understorey in the undisturbed semi-evergreen forests among dense leaf litter. We could locate<br />

only a single clump on the forest floor. The forest was dominated by Callophyllum polyanthum, Ostodes paniculata,<br />

Engelhardtia spicata, Diospyros toposia, Phoebe attenuata, Quercus polystachya, Cinnamomum bejolghota.<br />

Introduction<br />

14.0 <strong>Threatened</strong> <strong>Plants</strong> <strong>and</strong> Their <strong>Habitats</strong> in<br />

<strong>India</strong>n Thar Desert<br />

Amit Kotia<br />

Wildlife Institute <strong>of</strong> <strong>India</strong>, Ch<strong>and</strong>rabani, Dehradun<br />

kotia.amit@gmail.com<br />

The arid region <strong>of</strong> <strong>India</strong> lies between 24° to 29° N latitudes <strong>and</strong> 70° to 76° E longitudes. It occupies nearly 9% <strong>of</strong> <strong>India</strong>’s<br />

geographical area <strong>and</strong> covers 208,751 km² in Rajasthan alone <strong>and</strong> about 62180 km² in Gujarat (Rahmani 1997).<br />

Biogeographically, it is divisible into two provinces viz., Thar Desert <strong>of</strong> Rajasthan (3B) <strong>and</strong> Katchh Desert <strong>of</strong> Gujarat (3A)<br />

(Rodgers & Panwar 1988). The Thar Desert comprises southern Dune systems, northern Dune systems, eastern<br />

transition or Bagar located in Jalore, Jodhpur, Nagaur <strong>and</strong> Churu districts. The Katchh is further divisible into Little<br />

Rann, Great Rann, Isl<strong>and</strong>s <strong>and</strong> southern hills or Bets.<br />

The Thar Desert is the eastern extension <strong>of</strong> the vast Persio-Arabian desert, which joins the great Sahara desert. It is<br />

about 640 km long <strong>and</strong> 160 km wide. It is covered by a depth <strong>of</strong> several meters <strong>of</strong> s<strong>and</strong>s which are constantly shifted by<br />

winds blowing from the southwest (Krishnan 1982). The s<strong>and</strong> covers an irregular rocky floor, but occasionally local<br />

prominences <strong>and</strong> ridges rise above the level <strong>of</strong> the s<strong>and</strong>. Covering an area <strong>of</strong> around 62% in 12 districts <strong>of</strong> Rajasthan,<br />

this desert extends in the eastern part <strong>of</strong> Pakistan. S<strong>and</strong> dunes are present in nearly 58% <strong>of</strong> the area (Shankarnarayan<br />

1988).<br />

A major portion <strong>of</strong> western Rajasthan falls under S<strong>and</strong> dunes <strong>and</strong> s<strong>and</strong>y plains. Occurrence <strong>of</strong> saline-sodic soil with pH<br />

up to 9.0 is a common feature. The soils <strong>of</strong> the desert plains are s<strong>and</strong>y loam with a significant proportion <strong>of</strong> lime within<br />

150 cm <strong>of</strong> soil pr<strong>of</strong>ile (Dhir & Jain 1982).The average annual rainfall in the region is 275 mm <strong>and</strong> it is less than 100 mm<br />

in the extreme west. Luni River forms the main drainage system during rainy season. The climate <strong>of</strong> the desert region<br />

also shows extremes with temperatures ranging from sub-zero in winter to as high as 52°C in summer. Dust storms in<br />

the desert tracts may reach a velocity <strong>of</strong> 130 km/h <strong>and</strong> may deposit 50-75 mm <strong>of</strong> dust on the ground per storm. The<br />

relative humidity varies from 25% (April) to 85% (July). Frosts are generally severe during winter, particularly in the s<strong>and</strong>y<br />

areas. Tree saplings up to 2 m in height, sometimes, succumb to such frosts. The vegetation is extremely sparse in<br />

most <strong>of</strong> the l<strong>and</strong> forms <strong>and</strong> generally described as Tropical thorn scrub <strong>and</strong> desertic formations.<br />

The flora <strong>of</strong> the <strong>India</strong>n desert is an admixture <strong>of</strong> the western (65.8%) as well as the eastern (34.2%) taxa migrated from<br />

both the regions, while only 9.4% species are endemic (Anonymous 1988). Blatter & Hallberg (1988) reported 507<br />

species <strong>of</strong> flowering plants which was later updated by Bh<strong>and</strong>ari (1990). The flowering plants in <strong>India</strong>n desert including<br />

both indigenous <strong>and</strong> naturalized plants comprises <strong>of</strong> 682 species belonging to 356 genera <strong>of</strong> 87 families. Poaceae,<br />

Fabaceae, Asteraceae <strong>and</strong> Cyperaceae are the dominating families having about 111, 65, 41 <strong>and</strong> 36 species respectively<br />

(Bh<strong>and</strong>ari 1990). The flora <strong>of</strong> the Thar desert are adapted to exploit the special microhabitats influenced by peculiar<br />

topography, geology, edaphic <strong>and</strong> climatic conditions. The Thar Desert harbours about 16 endemic plant species<br />

(P<strong>and</strong>ey et al. 1983, Singh & P<strong>and</strong>ey 1999).<br />

<strong>Special</strong> habitats<br />

Extremely harsh climatic conditions <strong>and</strong> varied micro-topographic features give rise to various plant associations<br />

which exhibit stark seasonality. The vegetation is mainly dry open <strong>and</strong> interspersed grassl<strong>and</strong>s consisting mainly <strong>of</strong><br />

stunted, thorny or prickly shrubs <strong>and</strong> perennial herbs which are mostly drought resistant. The ephemerals come up<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

during the rainy season, complete their life cycle before the advent <strong>of</strong> summer <strong>and</strong> the bulk <strong>of</strong> area is once more<br />

transformed into open s<strong>and</strong>y plains, desolate <strong>and</strong> barren. Desert vegetation is mainly categorized on the basis <strong>of</strong> its<br />

habitat (Shetty & Singh 1987). This article gives basic information on some <strong>of</strong> the special habitats, corresponding<br />

vegetation <strong>and</strong> unique plants associations in the arid zone (Plates 14A & 14B).<br />

a. The S<strong>and</strong>y plain <strong>and</strong> S<strong>and</strong> dunes : The major portion <strong>of</strong> the desert is covered by s<strong>and</strong>y plains <strong>and</strong> s<strong>and</strong> dunes with<br />

varying degree <strong>of</strong> stability. The area is characteristic for its various vegetation associations in different regions. Generally<br />

the stabilized s<strong>and</strong>y plains <strong>and</strong> s<strong>and</strong> dunes are covered with vegetation <strong>of</strong> trees <strong>and</strong> shrubs viz., Leptadenia pyrotechnica,<br />

Crotalaria burhia, Sericostoma pauciflorum, Calligonum polygonoides, Capparis decidua, Lycium barbatum, Zizyphus<br />

nummularia, Aerva tomentosa, Calotropis procera, Acacia jacquemontii, Acacia senegal, Prosopis cineraria, Salvadora<br />

oleoides, S. persica, Tecomella undulata <strong>and</strong> Maytenus emarginatus. Common herbs include Argemone mexicana,<br />

Tephrosia purpurea, T. falciformis, Farsetia hamiltonii, Convolvulus microphyllous, Boerhavia diffusa, Heliotropium sp.,<br />

Indig<strong>of</strong>era linifolia, I. cordifolia, Tribulus terrestris, T. rajasthanensis <strong>and</strong> Echinops echinatus. Citrullus colosynthis, C.<br />

lanatus, Cucumis sp., Cocculus pendulus, Mukia maderaspatana, Momordica dioica, Coccinia gr<strong>and</strong>is <strong>and</strong> Pergularia<br />

daemia are the typical climbers <strong>of</strong> s<strong>and</strong>y plains <strong>and</strong> s<strong>and</strong> dunes. Some grasses viz., Aristida funiculata, A. adscensionis,<br />

Cenchrus ciliaris, C. biflorus, C. prieurii, C. setigerus, Eragrostis sp., Cyperus sp., Dactyloctenium sindicum, D. aegyptium<br />

<strong>and</strong> Lasiurus scindicus. Whereas inter dune areas also support similar vegetation but abundance <strong>of</strong> species may vary<br />

depending upon the availability <strong>of</strong> moisture <strong>and</strong> stability <strong>of</strong> s<strong>and</strong> dunes. S<strong>and</strong>y <strong>and</strong> unstable areas lack any vegetation<br />

but at times some ephemerals can be seen during the rainy seasons e.g., Cleome viscosa, Polycarpaea corymbosa,<br />

Corchorus tridens, Triumfetta pent<strong>and</strong>ra, Tribulus terrestris, Gisekia pharnaceoides, Mollugo cerviana, Mollugo<br />

nudicaulis, Pedalium murex, Sesamum indicum, Martynia annua, Amaranthus spinosus <strong>and</strong> Euphorbia sp. Cistanche<br />

tubulosa a root parasite usually seen in this habitat <strong>and</strong> commonly associated with Calligonum polygonoides, Capparis<br />

decidua <strong>and</strong> Calotropis procera.<br />

P<strong>and</strong>ey et al. (1983) <strong>and</strong> Bh<strong>and</strong>ari (1990) reported a few threatened plants from the s<strong>and</strong>y habitats, e.g., Gisekia<br />

pharnacioides, var. pseudopaniculata, Ceropegia bulbosa, Caralluma edulis, Tecomella undulata, Cleome gyn<strong>and</strong>ra<br />

var. nana, Convolvulus auricomus var. ferruginosus, Convolvulus auricomus var. volubilis, Convolvulus blatteri var.<br />

Convolvulus scindicus, Euphorbia jodhpurensis, Alysicarpus monilifer var. venosus, Psoralea odorata, Rhynchosia<br />

schimperi, Tephrosia falciformis, Abutilon pakistanicum, Zizyphus truncata, Withania coagulans, Tribulus rajasthanensis,<br />

Cenchrus prieurii, Cenchrus rajasthanensis <strong>and</strong> Ephedra ciliata.<br />

b. Gravelly or rocky plain : Gravelly pediments or rocky plains, known as Magra, are important areas <strong>of</strong> desert,<br />

generally seen around Pokaran - Jaisalmer, Barmer, Jodhpur <strong>and</strong> Bikaner. Common species <strong>of</strong> this habitat are Cleome<br />

vahliana, C. viscosa, C. gracilis, Fagonia indica, Rostellularia procumbens <strong>and</strong> Sericostoma pauciflora. Besides this,<br />

some common prostrate plants growing in the gravelly ground are Tribulus terrestris, Indig<strong>of</strong>era linnaei, I. linifolia, I.<br />

cordifolia, Heliotropium rariflorum, Euphorbia prostrata, E. granulata, E. clarkeana, Mollugo cerviana <strong>and</strong> Mollugo<br />

nudicaulis. Common shrubs <strong>of</strong> gravelly habitat include Euphorbia caudicifolia, Leptadenia pyrotechnica, Capparis<br />

decidua, Calotropis procera, Zizyphus nummularia, Acacia senegal, Prosopis cineraria, Salvadora oleoides <strong>and</strong><br />

Maytenus emarginatus. Dactyloctenium sindicum, Blepharis sindica, Melanocenchris jaquemontii, M. abyssinica,<br />

Oropetium thomaeum <strong>and</strong> Tragus roxburghii are some <strong>of</strong> the common grasses in such habitat. The rocky areas<br />

represent different geological formations ranging from shallow depressions to elevated areas <strong>and</strong> foot hills. The rocky<br />

slopes have typical species such as Anogeissus pendula, Asparagus racemosus, Balanites aegyptiaca <strong>and</strong> Euphorbia<br />

caudicifolia.<br />

According to P<strong>and</strong>ey et al. (1983) <strong>and</strong> Bh<strong>and</strong>ari (1990), the plants <strong>of</strong> gravel habitat which are threatened in Thar desert<br />

include Odontanthera varians, Commiphora wightii, Farsetia macrantha, Heliotropium rariflorum, Alysicarpus<br />

tetragonolobus, Monsonia heliotropioides, Abutilon bidentatum var. major, Pavonia arabica var. massuriensis, Tribulus


ajasthanensis Aristida royleana, Cenchrus prieurii var. scabra, Cenchrus prieurii var. prieurii <strong>and</strong> Cenchrus prieurii var.<br />

scabra.<br />

c. Small hillocks <strong>and</strong> rocky projections : There are many small hillocks <strong>and</strong> rocky projections isolated form Aravalli<br />

range e.g., Massuria hill, Mador, Kailana hill, Viratra hill, Neemdi <strong>and</strong> Mata ki phadi which support a rich assemblage<br />

<strong>of</strong> plants such as Capparis decidua, Grewia tenax, Euphorbia caudicifolia (<strong>of</strong>ten associated with root parasite Striga<br />

sp.), Rhus mysorensis, Commiphora wightii, Zizyphus nummularia, Acacia senegal, Anogeissus pendula, Boswellia<br />

serrata, Maytenus emarginatus along with herbs viz., Tephrosia sp., Convolvulus sp., Boerhavia diffusa, Heliotropium<br />

sp., Tridax procumbens, Tribulus terrestris, Anticharis senegalensis, Barleria sp., Rhynchosia minima, Asparagus<br />

racemosus <strong>and</strong> Fagonia indica.<br />

Some <strong>of</strong> the threatened taxa found in such habitat are: Convolvulus stocksii, Abutilon fruticosum var. chrysocarpa,<br />

Pavonia arabica var. massuriensis, Sida tiagii, Anticharis gl<strong>and</strong>ulosa var. caerulea, Tribulus rajasthanensis, Aristida<br />

royleana <strong>and</strong> Cenchrus prieurii var. scabra.<br />

d. Saline tracts : Saline-sodic soil is a common feature in this area with pH up to 9.0. Such habitats are characterized<br />

by the presence <strong>of</strong> salt tolerant taxa such as Prosopis juliflora, Tamarix indica, Trianthema portulacastrum, T. triquetra,<br />

Zaleya govidea, Chenopodium album, C. murale, Salsola baryosoma, Suaeda fruticosa, Haloxylon recurvum, Sesuvium<br />

sesuvioides, <strong>and</strong> Portulaca oleracea. Pulicaria rajputanae is endemic plant for saline habitat <strong>of</strong> Rajasthan <strong>and</strong> has very<br />

low abundance.<br />

e. Aquatic <strong>and</strong> marshy habitats : Some natural <strong>and</strong> artificial water bodies <strong>and</strong> marshes harbour characteristic<br />

aquatic species such as Lemna paucicostata, Naja graminea, N. welwitschii, Potamogeton crispus, P. pectinatus,<br />

Spirodela poyrhiza, Vallisneria spiralis, Nelumbo nucifera, water hyacinth Eichhornia crassipes <strong>and</strong> Wolffia species.<br />

According to P<strong>and</strong>ay et al. 1983, Ammannia desertorum is a threatened plant for aquatic habitat.<br />

<strong>Threatened</strong> <strong>Plants</strong><br />

Drastic changes in the l<strong>and</strong> use in recent decades <strong>and</strong> changes in habitat conditions due to invasion <strong>of</strong> alien invasive<br />

species are the major causes <strong>of</strong> concern in Thar Desert. For example, Indira G<strong>and</strong>hi Canal has changed the moisture<br />

regime <strong>and</strong> soil pH in many parts that has led to changed species composition <strong>and</strong> decline in typical desert species.<br />

Water hyacinth (Eicchornia crassipes), which never occurred in the region has invaded several water bodies. A few<br />

species <strong>of</strong> water logged habitat such as Arundo donax, Typha angustifloia, Phragmitis karka have proliferated in<br />

waterlogged areas (Prakash 2001). Invasion <strong>of</strong> a thorny shrub Prosopis juliflora is a major threat to native flora <strong>and</strong><br />

fauna. Some <strong>of</strong> the threatened plants <strong>of</strong> Thar Desert which need immediate conservation measures are mentioned<br />

below:<br />

(i) Ephedra foliata Boiss. & Kotschy. (Family Ephedraceae)<br />

Mundra Road, Bhuj – 370 001, Kachchh, Gujarat.<br />

Kachchh, the second largest district in <strong>India</strong> forms major portion <strong>of</strong> a biogeographic province within <strong>India</strong>n Desert<br />

(Rodgers et al. 2000). This dry l<strong>and</strong> is endowed with varied micro-habitats <strong>and</strong> an array <strong>of</strong> xerophytic vegetation adding<br />

uniqueness to the biodiversity <strong>of</strong> the Gujarat state <strong>and</strong> <strong>India</strong>. This district (45,652 km 2 ; 22 o 41' 11'' to 24 o 41' 47'' N <strong>and</strong><br />

68 o 9' 46'' to 71 o 54' 47'' E), located in the westernmost part <strong>of</strong> Gujarat state, covers about 73% <strong>of</strong> the total arid region<br />

in the state. It experiences extreme climatic conditions from very hot in summer (mean maximum temperature 39 –<br />

45 0 C) <strong>and</strong> cold (mean minimum 2 0 C) in winter. Droughts are frequent with normal rains once in two to three years,<br />

which averages to 326mm in 13 rainy days. These climatic conditions have resulted in unique habitats which vary from<br />

tropical thorn forest to extensive grassl<strong>and</strong>s, mangroves, mud flats along the coast, seasonal wetl<strong>and</strong>s <strong>and</strong> the most<br />

unique Rann (saline desert) interspersed with elevated l<strong>and</strong> masses, called ‘Beyts’. These habitats support several<br />

species <strong>of</strong> plants many <strong>of</strong> them are highly threatened.<br />

As per the classification by Champion & Seth (1968), as many as 14 different sub-types or categories <strong>of</strong> vegetation can<br />

be seen in the area. Approximately 768 plant species have been recorded from this region so far, which constitutes<br />

about 18% flora <strong>of</strong> the state (Shah 1978). However, being a typical desert, the region is marked by sparse vegetation<br />

cover <strong>and</strong> low biomass productivity. According to Nayar & Sastry (1988, 1990) as many as 48 species <strong>of</strong> vascular plants,<br />

typical <strong>of</strong> <strong>India</strong>n Deserts are found in the Kachchh region, which fall in one or other category <strong>of</strong> Red Data Book (RDB).<br />

Major causes <strong>of</strong> their depletion are ever increasing anthropogenic pressures, changes in l<strong>and</strong> use practices <strong>and</strong><br />

resultant alteration <strong>of</strong> natural habitats. Therefore, it becomes imperative to identify <strong>and</strong> locate populations <strong>of</strong> rare <strong>and</strong><br />

threatened taxa in different biogeographic zones <strong>and</strong> evolve strategies for their conservation. In this paper we present<br />

the findings <strong>of</strong> a short status survey <strong>of</strong> selected RDB plants in the Kachchh deserts <strong>of</strong> Gujarat <strong>and</strong> discuss the conservation<br />

strategies.<br />

Present Survey<br />

Nineteen plant species categorized as ‘<strong>Threatened</strong>’ by the World Conservation Monitoring Centre (1994) <strong>and</strong> also<br />

listed under various threat categories in the RDB <strong>of</strong> <strong>India</strong>n <strong>Plants</strong> (Nayar & Sastry 1988, 1990) were surveyed in the<br />

Kachchh region <strong>of</strong> Gujarat during 1998 to 2001. The localities from where these plants had been reported in the<br />

literature were revisited <strong>and</strong> known habitats were sampled for their populations. The survey was done using belt<br />

transects <strong>and</strong> circular plots (Mueller-Dombois & Ellenberg 1967, Kershaw 1973). The belt transects (1- 5 km x 6 m<br />

wide) were walked across the sampling patches along a fixed direction starting from a r<strong>and</strong>om point within the patch.<br />

The number <strong>of</strong> line transects depend upon the size <strong>of</strong> the patch. Along these transects the targeted species were<br />

searched. Whenever a threatened species was encountered, plant specific circular plots <strong>of</strong> varying radii (1m for herbs<br />

<strong>and</strong> 3m for shrubs <strong>and</strong> climbers) were laid to enumerate the number <strong>of</strong> individuals. In addition, site specific intensive<br />

search was made using belt transects (herb 10 x 2m <strong>and</strong> shrubs 25 x 4m) in six different directions leaving the line <strong>of</strong><br />

movement to document the abundance <strong>of</strong> the target species.<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Information on the type <strong>of</strong> habitat <strong>and</strong> perceived threats were recorded based on subjective rating (low, medium <strong>and</strong><br />

high). The major threats identified were: Habitat degradation (grazing <strong>and</strong> soil erosion), Habitat loss (industrial <strong>and</strong><br />

urban development, mining, agriculture expansion, encroachment), Natural factors (pest attack, low propagation) <strong>and</strong><br />

Exploitation (extraction <strong>and</strong> cutting). Threat status were assigned (based on status within survey area) to all these<br />

species within the study area by grouping them into highly threatened (HT), moderately threatened (MT) <strong>and</strong> less<br />

threatened (LT) categories. This was done based on the number <strong>of</strong> individuals, number <strong>of</strong> habitats <strong>and</strong> locations they<br />

were found. The species with 20 locations were classed as LT species. The total length <strong>of</strong><br />

transects sampled in various habitats were: Wetl<strong>and</strong> - 11kms, Open scrub - 40kms, Forest - 34kms, Grassl<strong>and</strong> - 19kms,<br />

Borders <strong>of</strong> agricultural fields - 18kms <strong>and</strong> coastal areas - 23kms. This exercise was attempted to prioritize the species<br />

which need immediate conservation action. Sighting locations were plotted on a base map to identify the threatened<br />

botanical hotspots for in-situ conservation.<br />

Results <strong>and</strong> Discussion<br />

Abundance <strong>and</strong> distribution: The 19 species surveyed include eight herbs, six shrubs <strong>and</strong> five herbaceous climbers.<br />

Among these, Carollocarpus conocarpus <strong>and</strong> Ammania desertorum had very low numbers i.e. seven (3 locations) <strong>and</strong><br />

16 individuals (two locations) respectively <strong>and</strong> had highly restricted distribution. Commiphora wightii <strong>and</strong> Helichrysum<br />

cutchicum showed wider distribution (75 <strong>and</strong> 40 locations respectively) <strong>and</strong> had 9774 <strong>and</strong> 6586 individuals respectively<br />

Habitat Specific Distribution: These species occupied six major habitat types, <strong>of</strong> which open scrub harboured highest<br />

number (eight) <strong>of</strong> species. These species had higher abundance in this habitat (35-100% <strong>of</strong> the total population). The<br />

second highest number <strong>of</strong> species (four) was recorded from grassl<strong>and</strong>s (51-82%) <strong>and</strong> three in forested (41-65%)


habitats (Figure 1). Ammania desertorum, Dactyli<strong>and</strong>ra welwitschii, Limonium stocksii <strong>and</strong> Schweinfurthia papilionacea<br />

were restricted to single habitat viz. wetl<strong>and</strong>s, agricultural <strong>and</strong> fallow l<strong>and</strong>s, coastal dunes <strong>and</strong> open scrub respectively.<br />

Heliotropium bacciferum var. suberosum (90%) also showed more affinity to the coastal habitats. Low abundance <strong>of</strong><br />

some species could be inherent <strong>and</strong> for others it may be failure <strong>of</strong> regeneration. Water availability during <strong>and</strong> after<br />

germination in desert region is uncertain, which leads to high stress <strong>and</strong> mortality <strong>of</strong> annual plants (Le Houwrou 1984,<br />

<strong>and</strong> Van Rooyen et al. 1991). Singh (1998) noticed low propagation <strong>of</strong> even perennials due to frequent drought <strong>and</strong> high<br />

grazing pressure in the semi-arid area <strong>of</strong> Saurashtra. It is true for arid Kachchh which experienced 14 spells <strong>of</strong> drought<br />

within 23 years i.e. 1972 – 1994 (Anonymous 1996).<br />

Commiphora wightii was recorded at 75 locations, eight areas (Talukas) <strong>and</strong> mostly occupied open scrub (57%) <strong>and</strong><br />

forest (40%) on undulating terrain (Figure 1). This being a hardy species is reported to occur on undulating terrain,<br />

loamy <strong>and</strong> gravelly soil, with shallow depth, pebbly substratum low grazing area with open canopy favoring high density<br />

(Dixit & Rao 2000).<br />

habitat degradation due to excessive livestock grazing (Table 2). A recent study on grassl<strong>and</strong>s <strong>of</strong> Kachchh estimated<br />

that out <strong>of</strong> nine Talukas, four were with very high <strong>and</strong> three with high intensity <strong>of</strong> grazing pressure (Anonymous 2004),<br />

which also induced erosion <strong>of</strong> top soil. It has been estimated that soil erosion in Kachchh ranges between 25-50% in<br />

different Talukas (Anonymous 1994).<br />

Habitat loss is the second major threat to affect several species. This includes mining <strong>and</strong> industrial development.<br />

Nine species were under the threat <strong>of</strong> natural factors, <strong>of</strong> which C. colocynthis <strong>and</strong> I. caerulea faced lack <strong>of</strong> regeneration.<br />

However, survey <strong>of</strong> these species after rainy season would give a true picture. Rest <strong>of</strong> the seven species were affected<br />

by termite attack (Table 2). Among the assessed 19 species, 13 species are reported to be medicinally important in<br />

Kachchh (Silori et al. 2005). Of these, C. colocynthis, D. welwistschii, E. foliata <strong>and</strong> S. papilionacea are used at low<br />

level, while C. wightii is heavily exploited for local medicine. It has been reported that a mature C. wightii ( Guggal), can<br />

produce 250-500 gm <strong>of</strong> gum (Atal et al. 1975) <strong>and</strong> an estimated 300-400 tones <strong>of</strong> Guggal has been sold in Bhuj every<br />

year. However, this plant was found to be widely distributed in Kachchh. Crude methods <strong>of</strong> gum extraction from younger<br />

plants (Joshi et al. 2004) is likely to affect its abundance in future.<br />

<strong>Threatened</strong> Botanical Hotspots: Nineteen threatened species were recorded from 337 locations covering all the nine<br />

Talukas <strong>of</strong> Kachchh district. <strong>Threatened</strong> Botanical Hotspots were identified by plotting all the 125 locations <strong>of</strong> only<br />

highly <strong>and</strong> moderately threatened species. Both HT <strong>and</strong> MT species were present in all the Talukas, except in Anjar.<br />

Among the talukas, Bhuj showed presence <strong>of</strong> 11 species at a maximum <strong>of</strong> 41 locations, which formed 32.80% <strong>of</strong> the<br />

total locations, followed by Abdasa (six species at 26 locations, forming 21%). Grouping <strong>of</strong> locations based on their<br />

distribution resulted in two threatened botanical hotspots. Of these, one hotspot is located in Abdasa taluka at the south<br />

western part. This hotspot identified as Naliya Biodiversity Reserve (NBR), is predominantly a grassl<strong>and</strong> habitat, locally<br />

known as Naliya grassl<strong>and</strong>. The second hotspot is located at southern part covering the area at the tri-junction <strong>of</strong> Bhuj,<br />

M<strong>and</strong>vi <strong>and</strong> Mundra talukas, which includes the forested areas <strong>of</strong> Megpar <strong>and</strong> Dhunai villages in M<strong>and</strong>vi, Kera <strong>and</strong><br />

Dahisara villages <strong>of</strong> Bhuj, <strong>and</strong> Dahisara Reserved Forests (Figure 2 & Plate 15). This has been identified as Kachchh<br />

<strong>Threatened</strong> Plant Reserve (KTPR), which included 30 (46.88%) <strong>of</strong> the total 64 locations <strong>of</strong> the three talukas. Further,<br />

this area is predominantly with hilly terrain dominated by Acacia senegal <strong>and</strong> A. nilotica thorn forest interspersed with<br />

Euphorbia cadusifolia <strong>and</strong> Grewia tenex open scrub.

Conservation Strategies :<br />

Status Survey <strong>of</strong> <strong>Threatened</strong> <strong>Plants</strong> in<br />

Kachchh Desert, Gujarat<br />

(i) Since majority <strong>of</strong> the threatened species are annuals <strong>and</strong> more susceptible to uncertain arid climate <strong>and</strong> prolonged<br />

drought, it would be necessary to carry out an intensive survey <strong>of</strong> these species following good monsoon which will<br />

give true picture <strong>of</strong> the distribution, abundance <strong>and</strong> regeneration status <strong>of</strong> these species.<br />

(ii) The intensive survey <strong>of</strong> HT <strong>and</strong> MT species would be needed so as to identify more sites <strong>and</strong> initiate in- situ<br />

conservation measures.<br />

(iii) The Naliya Biodiversity Reserve (NBR) encompasses the Naliya grassl<strong>and</strong> covering roughly 100km 2 <strong>of</strong> almost<br />

continuous grassl<strong>and</strong> with few shrubs (Savannah). This area needs to be brought under Protected Area Network,<br />

considering that this ecosystem itself is endangered <strong>and</strong> it is home <strong>of</strong> ten threatened animal species in addition to<br />

eight threatened plant species.<br />

includes the environs <strong>of</strong> Megpar <strong>and</strong> Dhunai villages in M<strong>and</strong>vi <strong>and</strong> Dahisara village <strong>of</strong> Bhuj, which includes Dahisara<br />

Reserved Forests that needs to be immediately brought under strict protection from wood cutting, livestock grazing,<br />

quarry lease (small scale mining), the major threats <strong>of</strong> the area. This can possibly be notified as a Kachchh<br />

<strong>Threatened</strong> Plant Reserve as it harbours overall nine threatened plants.<br />

(v) Considering the rarity <strong>of</strong> these species, steps should be taken immediately to grow or propagate both the HT <strong>and</strong> MT<br />

species in botanical gardens so as to conserve them as part <strong>of</strong> ex situ conservation plan. In addition, propagation<br />

techniques for the species which are under heavy exploitation for enthno-medicine should be developed <strong>and</strong> the<br />

possibilities <strong>of</strong> cultivating them must also be encouraged so as to reduce the pressure on the wild population.<br />

1kotia.amit@gmail.com The arid <strong>and</strong> semiarid region <strong>of</strong> <strong>India</strong> covers ca. 3,17,090 km 2 area <strong>and</strong> is mainly spread over seven states viz.,<br />

Rajasthan, Gujarat, Haryana, Maharashtra, Karnataka, Andhra Pradesh <strong>and</strong> portions <strong>of</strong> Jammu & Kashmir. Climatically,<br />

the semi-arid region (annual rainfall 400 – 1000 mm) is further divisible into two zones (Rodgers & Panwar 1988). The<br />

first zone lies in Rajasthan, Gujarat, Western Madhya Pradesh, Punjab <strong>and</strong> Haryana, immediately west <strong>of</strong> which lies the<br />

<strong>India</strong>n Desert. The second zone extends to the rain-shadow area <strong>of</strong> Western Ghats in Maharastra, Andhra Pradesh,<br />

Karnataka <strong>and</strong> Tamil Nadu. The former zone has been recognized as Zone 4 (semiarid) while the latter forms a part <strong>of</strong><br />

Zone-6 (the Deccan Plateau). Zone 4 is further divisible into 4A (The Punjab Plains) <strong>and</strong> 4B (Gujarat-Rajputana) (Plate<br />

16A). The semiarid region in the country is generally demarcated based on 400mm isohyets.<br />

The semiarid zone in <strong>India</strong> represents ‘Savannah’ vegetation <strong>and</strong> extensive xerophilous grassl<strong>and</strong>s rich in legumes<br />

<strong>and</strong> shrubs. Some <strong>of</strong> the wildlife protected areas in this region attain very high ungulate biomass e.g., Ranthambore,<br />

Sariska, Gir, Velavadar, Nalsarovar, Jessore, National Chambal Sanctuary, Karera Sanctuary, Kuno - Palpur Sanctuary,<br />

Mount-Abu Sanctuary, Sitamata <strong>and</strong> Kumbalgarh Sanctuary. Dicliptera abuensis, Strobilanthes hallbergii, Berberis<br />

asiatica, Ceropegia odorata, C. hirsuta, Ceropegia vincaefolia are some <strong>of</strong> the interesting plants <strong>of</strong> this zone. In this<br />

article we discuss salient features <strong>of</strong> semiarid vegetation in Rajasthan, Gujarat <strong>and</strong> Madhya Pradesh along with<br />

description <strong>of</strong> special habitats <strong>and</strong> some examples <strong>of</strong> threatened plants.<br />

Vegetation Characteristics<br />

In Rajasthan, Aravalli Hill range separates semiarid tract from the arid zone. The average annual rainfall to the east <strong>of</strong><br />

Aravalli ranges between 525-675 mm <strong>and</strong> reaches 1000 mm at some location. Eastern Rajasthan has rich alluvial soil<br />

that supports good forests <strong>and</strong> agricultural crops. The vegetation comprises Tropical Dry Deciduous Forests, Savannah<br />

woodl<strong>and</strong> <strong>and</strong> Tropical Thorn Forest. Anogeissus pendula is the dominant species. Other associates are Buchanania<br />

lanzan, Diospyros melanoxylon, Mitragyna parvifolia, Cassia fistula, Schrebera swietenioides, Pterocarpus marsupium,<br />

Holoptelea integrifolia, Butea monosperma <strong>and</strong> Mallotus philippensis. Boswellia serrata occupies hill crests <strong>of</strong> Aravallis,<br />

Terminalia arjuna forms riparian forests. Sterculia urens is distributed throughout Aravalli range <strong>and</strong> Anogeissus latifolia<br />

is mainly found in open forest <strong>of</strong> Aravallis range in southern Rajasthan. Other locally common species in the region are<br />

Kydia calycina, Mangifera indica, Woodfordia fruticosa, Lannea corom<strong>and</strong>elica, Cochlospermum religiosum, Flacourtia<br />

indica, Tectona gr<strong>and</strong>is <strong>and</strong> species <strong>of</strong> Bauhinia, Albizia, Acacia, Ziziphus, Capparis, <strong>and</strong> Ficus (Sharma & Tiagi 1979,<br />

Shetty & Singh 1987).<br />

The Gujarat state is divided into six geomorphologically distinct regions viz., South Gujarat, Central Gujarat, Aravalli<br />

<strong>and</strong> adjoining tract, Kathiavad Peninsula, the Kutchh Peninsula with the Rann (true saline desert) <strong>and</strong> the Costal tract.<br />

The semiarid region in the state is formed by Central Gujarat, Aravalli <strong>and</strong> adjoining tracts, Kathiavad Peninsula, with<br />

an average rainfall <strong>of</strong> 250mm to 1250mm. According to Champion & Seth (1968) four different forest types are found in<br />

this region viz., Tropical Moist Deciduous Forest, Littoral <strong>and</strong> swamp Forest, Tropical Dry Deciduous Forest <strong>and</strong><br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Northern Tropical Thorn Forest. Tectona gr<strong>and</strong>is, Anogeissus pendula, Boswellia serrata, Acacia nilotica, Euphorbia<br />

caducifolia, Flacourtia indica, Helicteres isora, Holarrhena antidysentrica, Bridelia squamosa, Emblica <strong>of</strong>ficinallis,<br />

Butea monosperma, Diospyros melanoxylon, Anogeissus latifoia, Lannea corom<strong>and</strong>elica, Sterculia urens, Mitragyna<br />

parviflora <strong>and</strong> species <strong>of</strong> Wrightia, Carissa, Zizyphus, <strong>and</strong> Capparis are common woody elements. Heteropogon<br />

contortus, Aristida spp., Eragrostis spp., Chloris spp., <strong>and</strong> Aeluropus spp., are the common grasses (Shah 1978,<br />

Patel 1971).<br />

The semiarid tract in Madhya Pradesh is represented by Chambal catchment extending up to Narmda <strong>and</strong> Betla<br />

Rivers. The forest types <strong>of</strong> the region are Tropical Dry Deciduous <strong>and</strong> Tropical Thorn Forests where more than 1000<br />

flowering plants have bean reported. The common tree species include Anogeissus latifoia, A. pendula, Tectona<br />

gr<strong>and</strong>is, Lannea corom<strong>and</strong>elica, Diospyros melanoxylon, Sterculia urens, Mitragyna parviflora, Butea monosperma,<br />

Emblica <strong>of</strong>ficinalls, Boswellia serrata, Bridelia squamosa <strong>and</strong> Hardwickia binata. Species composition at shrub<br />

<strong>and</strong> ground layer is similar to that <strong>of</strong> semiarid regions <strong>of</strong> Gujarat. A few climbers <strong>of</strong> this area include species <strong>of</strong><br />

Rhynchosia, Atylosia, Cocculus, Cissampelos, Ipomoea, Pergularia daemia, Pueraria tuberosa <strong>and</strong> Tinospora cordifolia<br />

(Verma et al. 1993).<br />

<strong>Special</strong> <strong>Habitats</strong><br />

Sambhar Lake<br />

Sambhar, the largest salt lake <strong>of</strong> the <strong>India</strong>, has been recognized as a wetl<strong>and</strong> <strong>of</strong> international importance i.e., Ramsar<br />

site (Plate 16A). The length is 32 km from northeast to southwest, while the width varies between 3-2 km. The wetl<strong>and</strong><br />

area is a key wintering area for tens <strong>of</strong> thous<strong>and</strong>s <strong>of</strong> flamingos <strong>and</strong> other migratory birds from northern Asia. The<br />

different group <strong>of</strong> algae (Cyanophyceae <strong>and</strong> Rhodophyceae) <strong>and</strong> bacteria growing in the lake provide striking water<br />

colour <strong>and</strong> support the lake ecology that, in turn, sustains the migrating wetl<strong>and</strong> birds. Distinguished among the<br />

species are halophytes, which can be seen in this area. Salsola baryosoma, Suaeda fruticosa, Haloxylon recurvum,<br />

Sesuvium sesuvioides, Chenopodium album <strong>and</strong> C. murale. The other species <strong>of</strong> interest around Sambhar lake<br />

include Portulaca oleracea, Trianthema portulacastrum, T. triquetra, Zaleya govidea, Aeluropus logopoides, Tamarix<br />

troupii, Acacia nilotica, Calotropis procera, Capparis deciduas, Salvadora oleoides <strong>and</strong> Prosopis juliflora.<br />

Rocky outcrops <strong>of</strong> Aravalli Ranges<br />

The metamorphic rocks <strong>of</strong> Aravalli generally support poor soil <strong>and</strong> sparse vegetation. The dominant species being<br />

Anogeissus pendula, commonly associated with Diospyros melanoxylon, Acacia leucophloea, Bauhinia racemosa<br />

<strong>and</strong> Wrightia tinctoria. In parts <strong>of</strong> Jaipur <strong>and</strong> Ajmer districts, Acacia senegal is common on the upper slopes with<br />

different plant associates e.g. Sterculia urens, Boswellia serrata <strong>and</strong> Lannea corom<strong>and</strong>elica <strong>and</strong> along the foothills with<br />

Butea monosperma. The other species found are Dichrostachys cineraria, Balanites aegyptiaca, Maytenus emarginata,<br />

Rhus mysurensis, Securinga leucopyrus, Grewia flavescens <strong>and</strong> G. tenax. Acacia catechu forests are common in the<br />

south-eastern regions <strong>of</strong> Rajasthan e.g. Baran, Jhalawar, Kota, Swaimadhopur, Chittorgarh <strong>and</strong> Alwar. The area under<br />

this type covers roughly 3% <strong>of</strong> the total forest area (Sharma & Tiagi 1979).<br />

Mount Abu<br />

Mount Abu, situated on the south western border <strong>of</strong> Rajasthan, is the highest peak between western Himalayas <strong>and</strong><br />

Nilgiri hills with a maximum height <strong>of</strong> 1727m. The vegetation is peculiar due to relatively high altitude together with<br />

climatic <strong>and</strong> edaphic factor for semiarid habitat <strong>and</strong> again highlights this area as a hotspot due to the presence <strong>of</strong> some<br />

endemic <strong>and</strong> threatened plants viz. Dicliptera abuensis, Strobilanthes hallbergii, Bonnaya bracteoides, Oldenl<strong>and</strong>ia<br />

clausa, Veronica anagallis var. bracteoa, Ceropegia odorata, C. hirsuta, C. vincaefolia, Ischaemum kingii, Rosa involucrate,


Sterculia villosa, Eulophia ochreata, Aerides crispum, A. multiflora, A. maculosum <strong>and</strong> V<strong>and</strong>a testacea <strong>and</strong> associated<br />

with common plants Carvia callosa, Erythrina sp., Kydia calycina, Mangifera indica, Mallotus pilippensis, Lannea<br />

corom<strong>and</strong>elica, Jasminum humile, Flacourtia indica, Crateva nurvala <strong>and</strong> Ficus spp. (Mehta 1979, Sharma &<br />

Kotia 2008).<br />

Ravines <strong>of</strong> Chambal<br />

Around 4.5 lakh hectares area in Madhya Pradesh <strong>and</strong> Rajasthan falls under ravines. These areas face a continuous<br />

threat <strong>of</strong> human encroachment for reclamation <strong>and</strong> habitation. Thorny bushes or small trees commonly found in this<br />

area include Capparis deciduas, Capparis sepiaria, Balanites aegyptiaca, Acacia senegal, A. nilotica, A. leucophloea,<br />

Prosopis juliflora, Butea monosperma, Maytenus emarginata, Tamarix sp., Salvadora persica, S. oleoides, Crotalaria<br />

medicaginea, C. burhia, Clerodendrum phlomidis, Calotropis procera, Xanthium indicum <strong>and</strong> Leptadenia pyrotechnica<br />

associated with climbers such as Maerua oblongifolia, Pergularia daemia, Ceropegia bulbosa, herbs e.g., Argemone<br />

mexicana, Farsetia hamiltonii, Tephrosia purpurea, Cleome viscosa, Tribulus terrestris, Glinus lotoides, Sericostoma<br />

pauciflorum, Rivea sp., Ipomoea sp., Pedalium murex, Sesamum mulayanum, Lepidagathis sp, Boerhavia diffusa,<br />

Chrozophora sp., <strong>and</strong> grasses like Cyprus sp., Fimbristylis sp., Brachiaria sp., Cenchrus sp., Dichanthium sp., etc.<br />

Malwa plateau<br />

The south-eastern part <strong>of</strong> Rajasthan, eastern part <strong>of</strong> Gujarat <strong>and</strong> western MP come under Malwa plateau. Anogeissus<br />

pendula, Acacia catechu, Boswellia serrata, Tectona gr<strong>and</strong>is, Aegle marmelos, Madhuca indica, Mitragyna parvifolia,<br />

Butea monosperma, Cassia fistula, Terminalia tomentosa, T. bellirica, Diospyros melanoxylon are the common species<br />

associated with various shrubs <strong>and</strong> grasses. Moist areas have good abundance <strong>of</strong> Syzygium sp., Terminalia arjuna,<br />

Mitragyna parvifolia, Hiptage bengalensis, Ixora arborea, Mangifera indica, Carissa congesta, Cissus sp. <strong>and</strong> Pueraria<br />

tuberosa among others.<br />

<strong>Threatened</strong> <strong>Plants</strong><br />

According to Puri (1952), P<strong>and</strong>ey et al. (1983), Sabnis & Rao (1983), Shah (1983), Shetty & Singh (1991) <strong>and</strong> P<strong>and</strong>ey<br />

& Teotia (2000) following plants have been recognized as typical <strong>and</strong> threatened species <strong>of</strong> semiarid zone: Dicliptera<br />

abuensis, Strobilanthes hallbergii, Bonnaya bracteoides, Oldenl<strong>and</strong>ia clausa, Veronica anagallis var. bracteoa, Ceropegia<br />

odorata, C. hirsuta, C. vincaefolia, Ischaemum kingii, Rosa involucrata, Sterculia villosa, Eulophia ochreata, Aerides<br />

crispum, A. multiflora, A. maculosum, Nervilia oragonna, V<strong>and</strong>a testacea, Anogeissus sericea var. nummularia, Blumea<br />

bovei, Chlorophytum bharuchae, Commiphora wightii, Convolvulus auricomus, C. stockii, Gloriosa superba, Heliotropium<br />

rariflorum, Tribulus rajasthanensis, T. jamnagarensis, Butea monosperma var. lutea, <strong>and</strong> Cochlospermum religiosum.<br />

Main threats for these plants include degradation <strong>of</strong> forests due to excessive biotic pressure including livestock<br />

grazing. Besides, invasive species like Prosopis juliflora <strong>and</strong> Lantana camara are big competitors <strong>and</strong> inhibitors for<br />

native flora as they occupy continuously major portion <strong>of</strong> habitat. Some <strong>of</strong> the threatened plants <strong>of</strong> the semiarid region<br />

which need immediate conservation attention (Plate 16B) are as follows:<br />

Berberis asiatica Roxb. ex DC. (Berberidaceae)<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Commonly found in the Himalayan region but a small isolated population can be seen in Mount Abu. This species has<br />

declined rapidly in Mount Abu due to habitat loss <strong>and</strong> over exploitation for its medicinal values.<br />

inner linear or elongate- triangular, erect, divergent at apex. Fl. & Fr.: Aug.-Sept.<br />

An endemic plant <strong>of</strong> <strong>India</strong>, distributed in Mount Abu (Rajasthan), Gujarat, Konkan <strong>and</strong> Maharashtra (Ansari 1984). Over<br />

exploitation <strong>of</strong> tubers, over grazing <strong>and</strong> rapid invasion by Lantana camara are the major causes fo its decline.<br />

Ceropegia vincaefolia Hook. f. (Asclepiadaceae)<br />

Local Name : Khilodia, Khadulia<br />

Tuberous twiner. Branches glabrous. Leaves 5-10cm, narrowly lanceolate or ovate-cordate, obtusely acuminate to<br />

acute. Flowers in few-umbellate cymes, peduncles hirsute, pedicels glabrous. Corolla 3-8 cm long, greenish. Blotched<br />

with purple, tube inflated at base, funnel-shaped at mouth, lobes pubescent inside. Follicles linear-lanceolate, finely<br />

pointed glabrous. Fl. & Fr.: July-Oct.<br />

A threatened plant for Maharashtra (Jain & Sikarvar 2004). It is distributed in Maharashtra <strong>and</strong> Rajasthan (Ansari 1984).<br />

It grows in the similar areas as Ceropegia odorata <strong>and</strong> has similar threats.<br />

Cordia crenata Delile. subsp. crenata (Boraginaceae)<br />

Local Name : Gundi<br />

According to P<strong>and</strong>ey & Teotia (2000) this taxon is almost extinct in wild. Small tree, wholly glabrous except minutely<br />

hairy inflorescence. Leaves alternate or subopposite, 2.5 - 7.5 cm long, elliptic or elliptic-lanceolate, rounded, subacute<br />

or shortly acuminate at the apex, obliquely rounded or crenate at the base, margins crenate- dentate or deeply<br />

dentate at least towards the apex. Flowers in small, compact, pendunculate cymes from the axils <strong>of</strong> the uppermost<br />

leaves. Drupes ca. 8 mm long, ovoid, acute. Fl. & Fr.: Jan.-April.<br />

Dicliptera abuensis Blatter (Acanthaceae)<br />

Much Branched, stragling shurbs. Leaves up to 5 x 2.75 cm, ovate, acute, subentire, sparingly hairy. Flowers in dense<br />

axillary cymes, white with deep pink tinge. Bracts 2, ovate-laneolate, unequal, with densely ciliate <strong>and</strong> scarious margins.<br />

First Type collection <strong>of</strong> this species was made from Mount Abu by Hallberg in 1916. After this, there is no collection<br />

recorded <strong>and</strong> population status in the wild has not been assessed. It is possible that its taxonomic status may be<br />

ambiguous.<br />

Strobilanthes hallbergii Blatter (Acanthaceae)<br />

Shrubs, up to 3 m high. Leaves 2.5 cm long, ovate-elliptic, acuminate, with dentate-ciliate margins. Flowers in spike,<br />

purple. Bracts 2, opposite, ovate, obtuse, entire. Calyx 5 partite, hairy. Corolla bearded at the throat with yellow hairs.<br />

According to Shetty & Singh (1991) <strong>and</strong> P<strong>and</strong>ey et al. (1983) it is an endemic <strong>and</strong> threatened plant <strong>of</strong> Mount Abu. Over<br />

exploitation for fuel wood, overgrazing <strong>and</strong> intention <strong>of</strong> Lantana camara are the main causes<br />

<strong>of</strong> its decline.<br />

Tecomella undulata Seem. (Bignoniaceae)<br />

Local Name : Rohida, Marwar Teak<br />

A small tree. Leaves simple, with undulating margin. Corymbs few flowered. Corolla tubular, orange - yellow. Stamens<br />

scarcely exerted. Seeds winged. Fl. & Fr.: Dec.-May.<br />

Its distribution is restricted to the drier parts <strong>of</strong> the Arabia, southern Pakistan <strong>and</strong> northwest <strong>India</strong>. In <strong>India</strong>, it occurs<br />

naturally in Maharashtra, Gujarat, Rajasthan, Punjab <strong>and</strong> Haryana. The species is mainly found in western Rajasthan.<br />

As Tecomella undulata wood is strong <strong>and</strong> durable, it forms a source <strong>of</strong> timber. It is also used widely in various Ayurvedic<br />

medicines. Hence, overexploitation is the reason for its decline.<br />

Tribulus rajasthanensis Bh<strong>and</strong>ari & Sharma (Zygophyllaceae)<br />

Local Name : Marwadi Gokharu<br />

Prostrate to procumbent, annual herb, branches hirsute. Leaves 1.5-4.5 cm, leaflets 4-7 pair, elliptic-oblong to ovateoblong,<br />

pubescent above, villous beneath. Flowers yellow, Stamens 10, 5mm long, Fruits c. 15mm across, mericarp<br />

densely hispid. Fl. & Fr.: Aug.-Nov.<br />

It is distributed in southern Rajasthan to North Gujarat <strong>and</strong> west Rajasthan to Pakistan. According to Jain & Sikarvar<br />

(2004) habitat loss is the major cause <strong>of</strong> threat.<br />

Human beings have been modifying their environment since time immemorial in a number <strong>of</strong> ways without giving<br />

much thought to the long term ecological consequences. Though human activities at low magnitude usually do not<br />

lead to palpable changes in the ecosystems but those <strong>of</strong> chronic <strong>and</strong> high magnitude have visually discernible<br />

impacts. Most obvious changes include local extinction <strong>of</strong> species, changes in community structure <strong>and</strong> composition,<br />

<strong>and</strong> modification <strong>of</strong> biophysical features in a l<strong>and</strong>scape. One <strong>of</strong> the most prominent examples where human impacts<br />

can be discerned is the Gangetic Khadar. Based on the physical structure, soil type, soil moisture <strong>and</strong> structure <strong>of</strong> floral<br />

<strong>and</strong> faunal communities the Gangetic plains can be divided in to two sub-regions, viz., the Khadar <strong>and</strong> Bhangar.<br />

Gangetic Khadar represents a unique biome in the sense that low lying areas remain inundated with water during most<br />

part <strong>of</strong> the year. Such low lying areas adjacent to the river course have tall wet grassl<strong>and</strong>s. It is followed by slightly raised<br />

ground, largely dry s<strong>and</strong>y beds, where short grasses grow along with some herbs <strong>and</strong> shrubs <strong>and</strong> termed as dry<br />

grassl<strong>and</strong>s. These s<strong>and</strong> beds merge into gently sloping <strong>and</strong> undulating terrain locally known as khola(s) which ultimately<br />

give way to the leveled plains (Bhangar). Kholas are characterized by s<strong>and</strong>y to loamy soil <strong>and</strong> used to support luxuriant<br />

growth <strong>of</strong> trees, shrubs, herbs <strong>and</strong> grasses. Today, there are a few places along the flood plains <strong>of</strong> Ganges where<br />

discrimination between Khola <strong>and</strong> Bahngar is possible. Most <strong>of</strong> the Kholas have now been leveled <strong>of</strong>f <strong>and</strong> converted<br />

into crop fields. Once extensive tracts <strong>of</strong> luxuriant tall wet grassl<strong>and</strong>s in this biome have now reduced to a few<br />

intermittent <strong>and</strong> relic patches in a modified l<strong>and</strong>scape. Dry grassl<strong>and</strong>s have also been extensively converted into<br />

This article presents salient findings <strong>of</strong> a case study on recent changes in l<strong>and</strong> use / l<strong>and</strong> cover <strong>and</strong> eco-floristic<br />

account <strong>of</strong> major habitats in Hastinapur Wildlife Sanctuary (HWS), Uttar Pradesh. Based on past floristic surveys<br />

conducted by various workers (Murty & Singh 1959, 1960, 1961) <strong>and</strong> recent update on the flora by the authors (Khan<br />

1987, 2000, 2002, 2003, 2005; Khan & Khan 2000; Khan et al. 1984, 1985, 1986, 2006), the habitat specificity <strong>and</strong><br />

declining trends in some species <strong>and</strong> preponderance <strong>of</strong> a few alien invasive plants are presented along with a plea for<br />

conservation <strong>of</strong> this highly threatened ecosystem as this is perhaps the only area along the the Ganges which still holds<br />

few natural patches <strong>of</strong> the Gangetic Khadar.<br />

The Hastinapur Wildlife Sanctuary<br />

The HWS (28 o 462 to 29 o 352 N <strong>and</strong> 77 o 302 to 78 o 302 E), covering an area <strong>of</strong> 2073 km 2 , along the banks <strong>of</strong> the Ganges<br />

was established in 1986 with stated objective <strong>of</strong> conserving <strong>and</strong> preserving an example <strong>of</strong> Gangetic Khadar biome <strong>and</strong><br />

its attendant fauna especially the swamp deer (Cervus duvauceli duvauceli). The sanctuary is heavily interspersed by<br />

human habitation <strong>and</strong> agriculture with several hundred villages inside <strong>and</strong> a few large cities at the periphery. Broadly,<br />

it has three distinct habitats types, viz., (i) the tall wet grassl<strong>and</strong>s (swamps), (ii) short dry grassl<strong>and</strong>s, <strong>and</strong> (iii) forests on<br />

Khola. A sizable portion <strong>of</strong> the sanctuary i.e., about 32% is under cultivation while only about 10% is covered by tall<br />

wet grassl<strong>and</strong>s. About 13% is scrub, 5% dry grassl<strong>and</strong>s <strong>and</strong> an equal proportion is under the category <strong>of</strong> forest (Plate<br />

17A & 17B).<br />

Recent Changes in L<strong>and</strong> Use <strong>and</strong> L<strong>and</strong> Cover<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

An analysis <strong>of</strong> recent changes in l<strong>and</strong> use / l<strong>and</strong> cover in <strong>and</strong> around HWS was carried out using remote sensing data<br />

<strong>and</strong> it was revealed that between 1992 <strong>and</strong> 2000 tall wet grassl<strong>and</strong>s have shrunk by 21.2% (223.58 km 2 in 1992 <strong>and</strong> 176<br />

km 2 in 2000) <strong>and</strong> the forest area has reduced by 59.0% (201.44 km 2 in 1992 <strong>and</strong> 81.37 km 2 in 2000). At the same time<br />

this area has witnessed 28% increase in agiculture <strong>and</strong> about 68% increase in other infrastructure especially buildings.<br />

Such large scale changes in the l<strong>and</strong>use/ l<strong>and</strong>cover must have had significant impacts on the biological community<br />

in this ecosystem. However, in the absence <strong>of</strong> any baseline data <strong>and</strong> indepth scientific study it would be rather difficult<br />

to ascertain the magnitute <strong>of</strong> impact <strong>and</strong> exact changes in the ecosystem characteristics <strong>and</strong> species composition.<br />

There are only a few past records on selected taxa which provide some clue to the changing scenario on the region.<br />

For instance, Schaller (1972) observed large herds <strong>of</strong> swamp deer comprising several hundred individuals in <strong>and</strong><br />

around the present limits <strong>of</strong> HWS during early 1960’s. Today, swamp deer population is reduced to less than 500 <strong>and</strong><br />

confined to a few scattered small groups within the limit <strong>of</strong> HWS only. A small <strong>and</strong> relict population (ca. 120) has recently<br />

been located some 100 kms north <strong>of</strong> this sanctuary along the course <strong>of</strong> Ganges in Haridwar district <strong>of</strong> Uttarakh<strong>and</strong>.<br />

The two populations might have been contiguous in the historical past. The changes in floristic composition over the<br />

last few decades is hard to assess due to the paucity <strong>of</strong> detailed analysis <strong>of</strong> flora. Considering these gaps we conducted<br />

surveys to document floristic composition within the sanctuary<br />

Floristic Structure <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong><br />

Extensive floristic surveys were conducted during 2003 to 2006 covering major habitat types <strong>of</strong> Gangetic Khadar in <strong>and</strong><br />

around HWS through a project funded by the Ministry <strong>of</strong> <strong>Environment</strong> <strong>and</strong> Forests (Khan et al. 2006). During these<br />

surveys a total <strong>of</strong> 740 species <strong>of</strong> angiosperms, belonging to 452 genera <strong>and</strong> 123 families, were collected, identified <strong>and</strong><br />

recorded from this area. As expected, largest family <strong>of</strong> flowering plants in the sanctuary is grass Family (Poaceae) with<br />

60 genera <strong>and</strong> 108 species, followed by Leguminosae (43 genera <strong>and</strong> 94 species; <strong>of</strong> which Fabaceae was the richest<br />

having 31 genera <strong>and</strong> 62 species). Asteraceae (42 gen., 59 spp.) <strong>and</strong> Cyperaceae (10 gen., 43 spp.) are other<br />

dominant families. Brassicaceae, Apiaceae <strong>and</strong> Rubiaceae had relatively high generic diversity <strong>and</strong> lower species<br />

diversity. Following is the general statistics <strong>of</strong> the flora <strong>of</strong> HWS:<br />

Table 1: Number <strong>of</strong> Dicot <strong>and</strong> Monocot (Angiosperm) Families, Genera <strong>and</strong> Species recorded from Hastinapur<br />

WS, Uttar Pradesh.<br />

Group Number <strong>of</strong> Families Number <strong>of</strong> Genera Number <strong>of</strong> Species<br />

Dicots 98 345 540<br />

Monocots 25 107 200<br />

Total 123 452 740<br />

A comparison <strong>of</strong> present floristic inventory <strong>and</strong> earlier record (Murty & Singh 1961) reveals that while 425 angiosperm<br />

species were recorded in both the studies, as many as 117 species reported earlier could not be found during the<br />

present study. Some examples <strong>of</strong> such plants include Ranunculus aquatilis, Maerua arenaria, Hybanthus enneaphylla,<br />

Abutilon hirtum, Abutilon ramosum, Kydia calycina, Corchorus tridens, Fagonia arabica, Atylosia platycarpa, Crotalaria<br />

alata, C. mysorensis, Dalbergia latifolia, Indig<strong>of</strong>era cordifolia, Lathyrus sativus, Rhynchosia sericea, Uraria picta,<br />

Cassia obtusifolia, Acacia gageana, A. sinuata, Melothria purpusilla, Morinda tinctoria, Artemisia parviflora, Carthamus<br />

oxyacantha, Cotula anthemoides, Launaea asplenifolia, Seigesbeckia orientalis, Leptadenia pyrotechnica, Enicostemma<br />

axillaris, Hydrolea zeylanica, Heliotropium eichwaldii, Acalypha ciliata, Breynia vitis-idaea, Sapium sebiferum, Commelina<br />

attenuata, Cyanotis cristata, Aponogeton natans, Fimbristylis aestivalis, F. cynosa, Juncellus inundatus, Kyllinga<br />

nemoralis, Mariscus compactus, M. squarrosus, Acrachne racemosa, Aristida funiculata <strong>and</strong> A. hystrix.<br />

The study, however, resulted in the collection <strong>of</strong> 196 species which had not been recorded by the earlier authors. Many<br />

<strong>of</strong> these species are recently naturalized exotics or alien invasive species. Invasion by such species had initially been<br />

recorded by Singh (1973). The species which have seemingly declined during recent decades <strong>and</strong> now highly

threatened include Bacopa monnieri, Hygrorhiza aquatica, Coix lachryma-jobi, Sisymbrium irio, Capparis zeylanica,<br />

Hypericum japonicum, Crotalaria orixensis, Alternanthera philoxeroides, Polygonum plebejum var. sindica, Rumex<br />

crispus <strong>and</strong> Mallotus philippensis.<br />

Some <strong>of</strong> the species recorded in the study area are specific to certain peculiar habitat types, for instance, Celastrus<br />

paniculata, Combretum nanum, Galium aparine, Gloriosa superba, Jasminum arborescens <strong>and</strong> Mallotus philippensis<br />

were restricted to Kholas only, while Cephalanthus tetr<strong>and</strong>ra <strong>and</strong> Epilobium hirsutum were found only in swamps or tall wet<br />

grassl<strong>and</strong>s. The wetl<strong>and</strong>s are most vulnerable to local extension due to over growth <strong>of</strong> alien invasive species such as<br />

Eichornia crassipes, Cyathocline purpurea <strong>and</strong> Potamogeton nodosus.<br />

Conclusions<br />

The Hastinapur WS represents a small sample <strong>of</strong> highly threatened hygrophilous grassl<strong>and</strong> ecosystem (Gangetic<br />

Khadar). The entire Terai ecosystem in Upper Gangetic Plain including this sanctuary has been facing onslaught <strong>of</strong><br />

anthropogenic pressures leading to degradation <strong>and</strong> transformation <strong>of</strong> natural habitat <strong>and</strong> representative biota including<br />

threatened swamp deer <strong>and</strong> several species <strong>of</strong> plants. Some <strong>of</strong> the plant species recorded as frequent during early<br />

1960s have gone locally extinct <strong>and</strong> other species are surviving in extremely low abundance. Considering the present<br />

rate <strong>of</strong> habitat loss (about 10% per annum) <strong>and</strong> rapid invasion by exotic species it is plausible that several remnant<br />

habitat isl<strong>and</strong>s <strong>and</strong> extant fragmented populations <strong>of</strong> native flora <strong>and</strong> fauna species would be vanished from this<br />

biogeographic region. This calls for an urgent conservation initiative on part <strong>of</strong> the government as well as nongovernment<br />

agencies in order to save this fast vanishing biome.<br />

<strong>and</strong> Strategies for Their Conservation<br />

Department <strong>of</strong> Botany, Shivaji University,<br />

Kolhapur-416004 (MS)<br />

1sryadavdu@rediffmail.com Ceropegia L. (Asclepiadaceae), a pantropical Old World genus <strong>of</strong> about 200 species exhibits a tremendous diversity<br />

with reference to habit, habitat, flower architecture <strong>and</strong> ecological adaptations. It is distributed over most <strong>of</strong> Africa,<br />

Madagascar, the Arabian Peninsula, the <strong>India</strong>n subcontinent, the Far East <strong>and</strong> Northern parts <strong>of</strong> Australia. Ansari (1984)<br />

revised the <strong>India</strong>n Ceropegia <strong>and</strong> reported 44 species, <strong>of</strong> which 28 are said to be endemic to <strong>India</strong>. After this revision,<br />

some 5 novelties have been added to the list. Presently the genus is represented by about 50 species <strong>of</strong> which about 38<br />

occur in Western Ghats. Several species <strong>of</strong> Ceropegia are narrow endemics <strong>and</strong> fall under one or another IUCN Red-<br />

List category (Nayar <strong>and</strong> Sastry, 1987-89). In recent years, the genus has attracted an attention <strong>of</strong> several workers due<br />

to rarity <strong>of</strong> its species <strong>and</strong> recognized importance <strong>of</strong> conservation <strong>of</strong> rare plants <strong>of</strong> the globe. Species <strong>of</strong> Ceropegia<br />

possess curious flytrap flowers (Percival, 1969) with great diversity in flower design; corolla size, shape <strong>and</strong> coloring<br />

patterns; corona structures <strong>and</strong> mechanisms for illumination <strong>of</strong> essential organs (Yadav, 1996). Pollination biology <strong>of</strong><br />

<strong>India</strong>n species has been studied to some extent by Chaturvedi, 1993a, 1993b <strong>and</strong> Yadav, 1996. Morph-taxonomical<br />

(Patil, 1990) <strong>and</strong> physiological studies (Gaikwad et al., 1989; Supate et al., 1990) on some <strong>of</strong> the <strong>India</strong>n species <strong>of</strong><br />

Ceropegia have helped in better underst<strong>and</strong>ing <strong>of</strong> morpho-physiological adaptations in the genus.<br />

Most <strong>of</strong> the endemic species <strong>of</strong> Ceropegia, by virtue <strong>of</strong> being restricted only to a special habitat <strong>and</strong> narrow ecological<br />

niche, are highly vulnerable <strong>and</strong> merit special consideration in their conservation. Reasons for their decline are many,<br />

e.g., destruction <strong>of</strong> forests, modifications <strong>of</strong> habitats, industrialization, pollution <strong>and</strong> introduction <strong>of</strong> exotic weeds, etc. In<br />

order to evolve long term conservation strategies for this group, it is essential to collate information on their distribution,<br />

present status, immediate threats, etc. In this article, we give a brief overview <strong>of</strong> the threatened Ceropegias <strong>of</strong> Western<br />

Ghats (Plates 18A & 18B), information on their habitats, threats <strong>and</strong> ways to conserve them.<br />

The <strong>Threatened</strong> Ceropegias <strong>of</strong> Western Ghats<br />

The IUCN criteria for assigning threat categories to species <strong>of</strong> Ceropegia are at times difficult to meet. For example,<br />

some <strong>of</strong> the endemic species are known only from type locality <strong>and</strong> the individuals are to meet very sparsely distributed.<br />

It would be virtually impossible to come up with information on total population especially in case <strong>of</strong> sparsely distributed<br />

species which can be identified only in flowers. In any case, all the endemic Ceropegias deserve special status <strong>and</strong><br />

dem<strong>and</strong> immediate conservation measures. So far 38 species <strong>of</strong> Ceropegia have been reported from the Western<br />

Ghats. Based on an extensive <strong>and</strong> intensive search <strong>of</strong> this genus made by the authors, especially in the Northern<br />

Western Ghats, it can be said that <strong>of</strong> the 38 species 15 are narrow endemic <strong>and</strong> all <strong>of</strong> them are highly threatened.<br />

Based on detailed field investigations, present distribution <strong>and</strong> status, phenology, ecology <strong>and</strong> threats for these species<br />

have been summarized below.<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Field note: It is a tuberous, twining, narrow leaved species with many flowered cyme. It is restricted to higher peaks <strong>of</strong><br />

Sahyadri ranges. It grows among the grasses (Tripogon lisboe) on steep western slopes <strong>of</strong> Sahyadri from 700 to 1200<br />

m altitude. It enjoys misty climate prevailing in the region from June- Sept.<br />

Remarks: It has glistening snow-white flowers <strong>and</strong> flat topped curiously formed corolla. It grows well in garden. Larvae<br />

<strong>of</strong> some butterflies feed on the leaves. Tubers are edible. It is <strong>of</strong> phytogeographical significance as the species<br />

possesses form <strong>of</strong> corolla similar to some <strong>of</strong> the species found in Africa.<br />

Field note : It is a tuberous, erect, narrow leaved species with one-flowered cyme. It grows in crevices<br />

<strong>of</strong> lateritic plateaus <strong>of</strong> higher altitudes (1200-1400 m). It grows in open rocky grounds on tops <strong>of</strong> Sahyadri ranges.<br />

Remarks : The tubers are edible <strong>and</strong> mostly eaten by cowboys. It has curiously formed <strong>and</strong> beautifully coloured<br />

flowers. It faces problems in sexual reproduction probably due to disappearance <strong>of</strong> the pollinators. As the species is<br />

very specific in its edaphic <strong>and</strong> climatic requirements, it is difficult to maintain in gardens <strong>and</strong> needs in-situ conservation.<br />

In <strong>India</strong>, Ceropegia bulbosa <strong>and</strong> C. hirsuta are the only two widespread species. Out <strong>of</strong> the 38 species in Western<br />

Ghats, 32 are endemic to the region. About 15 species <strong>of</strong> Northern Western Ghats are narrow endemics <strong>and</strong> some <strong>of</strong><br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

them are known only from their type localities. Ceropegia anjanerica, C. evansii, C. fantastica, C. huberi, C. lawii, C.<br />

maccannii, C. mahabalei, C. mohanramii, C. noorjahaniae, C. odorata, C. panchganiensis, C. rollae, C. sahyadrica, <strong>and</strong><br />

C. santapaui are critically endangered <strong>and</strong> if not cared for may vanish during the next few decades.<br />

<strong>India</strong>n species could be grouped into three groups on the basis ecophysiological <strong>and</strong> leaf characters. Ceropegia<br />

bulbosa possess succulent stem as well as leaves while C. juncea has small reduced scaly leaves <strong>and</strong> fleshy green<br />

stem. Both the species show Crassulean Acid Metabolism (CAM) (Supate et al. 1990; Gaikwad et al. 1989) <strong>and</strong> grow<br />

in comparatively drier parts <strong>of</strong> the country. Majority <strong>of</strong> the species have membranous broad or narrow leaves, C 3<br />

pathway <strong>of</strong> photosynthesis <strong>and</strong> grow in semi-evergreen, evergreen forests, shrubby vegetation <strong>and</strong> on plateaus. Erect<br />

species usually grow in open grassy grounds, while climbing species grow in open shrubby forest. While erect habit is<br />

the inevitable result <strong>of</strong> open situations, climbing habit is in response to the support.<br />

Tubers are starchy <strong>and</strong> edible. Some <strong>of</strong> the wild animals feed on Ceropegia tubers. Some <strong>of</strong> the butterflies rear on<br />

Ceropegia species <strong>and</strong> complete their life cycles. Some <strong>of</strong> the butterflies are host specific <strong>and</strong> disappearance <strong>of</strong><br />

Ceropegia species may also lead to their disappearance from the region. Therefore, Ceropegias have well-established<br />

biological role. The tubers are used as a nutritive tonic in the bowel complaints <strong>of</strong> children that cure dysentery <strong>and</strong><br />

diarrhoea. The alkaloid ceropegin from the tubers <strong>of</strong> C. bulbosa is used in Bihar in cold, eye-diseases <strong>and</strong> to cure<br />

sneezing (Kirtikar & Basu 1975.). The tuber <strong>of</strong> C. bulbosa is bitter, cures diarrhoea <strong>and</strong> dysentery, inflammation <strong>of</strong> gums<br />

<strong>and</strong> delirious fevers <strong>of</strong> parturition [Ayurveda] (Kirtikar & Basu 1975).<br />

The Stapelieae to which Ceropegias belong are principally adapted to fly-pollination <strong>and</strong> have reached a great<br />

diversity in flower architectures (Leach 1978, Dyer 1983, Bruyns & Forster 1991, Endress 1994). The most complicated<br />

flowers <strong>of</strong> dicots are found in the genus Ceropegia, which, in itself, is a wealth <strong>of</strong> wonderful radiation (Huber 1957, Vogel<br />

1961, Endress 1994). <strong>India</strong>n Ceropegia species possess strange flowers <strong>of</strong> beauty <strong>and</strong> curiosity (Yadav 1996). The<br />

flytrap flowers <strong>and</strong> pollination mechanisms in the species <strong>of</strong> Ceropegia are interesting in underst<strong>and</strong>ing diversification<br />

<strong>and</strong> evolution <strong>of</strong> the genus.<br />

Both Africa <strong>and</strong> Peninsular <strong>India</strong> belong to the same Gondvanal<strong>and</strong> <strong>and</strong> possess closely allied Ceropegia species <strong>of</strong><br />

phytogeographical significance, which like many other examples, support theory <strong>of</strong> continental drift. Ceropegia bulbosa<br />

shows close relationship with C. linophyllum from West Africa; C. mahabalei has clear affinities to African species C.<br />

campanulata-C. insignis - C. turricula group; some <strong>of</strong> the non-succulent species without tubers from the Western ghats<br />

seem to be both vegetatively <strong>and</strong> florally quite similar to species from West Africa <strong>and</strong> even to C. cumingiana from<br />

Australia while C. juncea is not closely allied to any other species (Bruyns 1997).<br />

Most <strong>of</strong> the <strong>India</strong>n species <strong>of</strong> Ceropegia are very specific in their habitat preferences. The starchy tubers are prone to<br />

fungal infections <strong>and</strong> thus decay <strong>of</strong> tubers is major problem in their cultivation <strong>and</strong> maintenance. They dislike organic<br />

manure <strong>and</strong> excess watering. There is an urgent need for both ex-situ as well as in-situ conservation <strong>of</strong> Ceropegias.<br />

Species <strong>of</strong> Ceropegia are very difficult to propagate, cultivate <strong>and</strong> maintain in gardens. Conservation <strong>of</strong> Ceropegia species<br />

is a challenge to biologists. Concentrated <strong>and</strong> co-ordinated efforts by universities, forest departments, <strong>and</strong> local communities<br />

are needed to save Ceropegias <strong>of</strong> Western Ghats.<br />

Short Term <strong>and</strong> Long Term Conservation Strategies<br />

Prodigious task <strong>of</strong> saving vanishing Ceropegias <strong>of</strong> Western Ghats:<br />

1. They are restricted in distribution <strong>and</strong> each has species-specific edaphic/climatic requirements.<br />

2. The individuals <strong>of</strong> endemic species are very sparsely distributed <strong>and</strong> extremely rare in occurrence being<br />

restricted to small areas in remote places.<br />

3. The tubers <strong>of</strong> Ceropegias are exploited by cowboys, cattlemen <strong>and</strong> also eaten by wild animals.

4. There is a great pressure on Western Ghats due to modification <strong>and</strong> destruction <strong>of</strong> the habitats leading to<br />

further decline <strong>and</strong> fragmentation <strong>of</strong> populations.<br />

5. Most complicated flowers with highly specialized pollination mechanisms <strong>and</strong> species-specific pollinators<br />

resulting into low fruit <strong>and</strong> seed setting.<br />

6. Many <strong>of</strong> seeds are worn out as they do not reach to proper place for seed germination <strong>and</strong> seedling establishment.<br />

7. There is no easy way for their propagation.<br />

8. The tubers are highly susceptible to microbial/fungal decay.<br />

9. It is extremely difficult to maintain <strong>and</strong> store the tubers during dry spell <strong>of</strong> the year.<br />

10. It is difficult to simulate growth requirements in ex situ conditions.<br />

11. Destruction <strong>of</strong> aerial plant parts by caterpillars.<br />

12. There are no apparent direct economic gains from Ceropegia species <strong>and</strong> unawareness <strong>of</strong> policy makers,<br />

people <strong>and</strong> researchers.<br />

Ways to save Ceropegias <strong>of</strong> Western Ghats :<br />

Micro-propagation is the only viable means to get planting materials. Hardening <strong>of</strong> plant materials is another critical<br />

step in reintroduction <strong>of</strong> planting material, which needs to be st<strong>and</strong>ardized. Following are probable <strong>and</strong> appropriate<br />

steps in saving the fascinating group <strong>of</strong> Ceropegias <strong>of</strong> Western Ghats.<br />

1. Protecting habitats <strong>of</strong> Ceropegias.<br />

2. Micropropagation <strong>and</strong> reintroduction.<br />

3. Study pollination biology <strong>and</strong> fruit setting in Ceropegia species <strong>and</strong> to know constraints in sexual reproduction<br />

<strong>and</strong> production <strong>of</strong> seeds.<br />

4. Establish methods for maintenance, storage <strong>and</strong> protection <strong>of</strong> tubers from microbes/fungi,<br />

5. Underst<strong>and</strong> suitable edaphic <strong>and</strong> climatic factors in maintenance <strong>of</strong> Ceropegia species.<br />

6. Training forest <strong>of</strong>ficials in identification, protection <strong>and</strong> maintenance <strong>of</strong> Ceropegia species.<br />

7. Cryo-preservation <strong>of</strong> germplasm <strong>of</strong> Ceropegias.<br />

8. Develop package <strong>of</strong> practices to grow, maintain <strong>and</strong> protect Ceropegia species.<br />

9. Coordinated efforts <strong>of</strong> researchers, forest <strong>of</strong>ficials <strong>and</strong> people to grow, maintain <strong>and</strong> protect Ceropegia species.<br />

10. Popularization <strong>of</strong> Ceropegias through workshops, greeting cards, calendars, <strong>and</strong> photographs <strong>and</strong> distribution<br />

<strong>of</strong> planting materials to nurseries, botanical, private <strong>and</strong> home gardens.<br />

11. Provision <strong>of</strong> finance for micro-propagation <strong>and</strong> hardening <strong>of</strong> Ceropegia species.<br />

12. Establish field gene bank <strong>of</strong> all the Ceropegia species <strong>of</strong> Western Ghats.<br />

13. Undertake restoration programs on Ceropegias<br />

The Palni Hills are an eastward spur <strong>of</strong> the Western Ghats in Tamil Nadu connected to the larger Annamalai hills <strong>of</strong><br />

Kerala. They have a maximum (east to west) length <strong>of</strong> 65 km, a maximum width <strong>of</strong> 40 km (mean width 24km) <strong>and</strong> an<br />

area <strong>of</strong> 2068 sq km. The hills fall into two geographically distinct zones, the upper <strong>and</strong> the lower Palnis, divided by a<br />

pass running from Palni in the north towards Periakulam in the south. The base rock <strong>of</strong> the Palnis is almost entirely<br />

Charnockite; a bluish black granite formed some two <strong>and</strong> a half billion years ago. Soils, generally a s<strong>and</strong>y loam<br />

belonging to a class <strong>of</strong> “red” (black) soils common in S. <strong>India</strong>. Being in the rain shadow <strong>of</strong> the main body <strong>of</strong> the Western<br />

Ghats, the upper hills remain relatively dry during the south west monsoon but receive heavy cyclonic rains during the<br />

retreating north east monsoon in October to December. Total annual rainfall is c.1665mm while the general climate is<br />

<strong>of</strong>ten described as quasi temperate with the maximum temperature being about 25ºC. <strong>and</strong> the minimum 4ºC. Frost<br />

<strong>of</strong>ten occurs in the hollows <strong>of</strong> the plateau during December <strong>and</strong> January.<br />

The upper Palnis above 1500m<br />

After years <strong>of</strong> deliberation, we have come to the conclusion that 1500m is the altitude at which the Shola grassl<strong>and</strong> ecosystem<br />

should begin in these hills, while at the same time recognising that the western plateau around 385sq km has<br />

a unique character <strong>of</strong> its own. The plateau, at an average altitude <strong>of</strong> 2200m, originally consisted <strong>of</strong> undulating grassl<strong>and</strong>s<br />

with numerous streamlets <strong>and</strong> marshes with peaks rising to 2500m. Within the sheltered folds <strong>of</strong> these extensive<br />

grassl<strong>and</strong>s pockets <strong>of</strong> woodl<strong>and</strong> locally known as Sholas are found.<br />

These Sholas <strong>of</strong>ten stretch down from the slopes <strong>and</strong> valleys <strong>of</strong> the plateaus providing corridors between the lower <strong>and</strong><br />

upper hills. The evergreen trees <strong>of</strong> the Sholas are characteristically stunted, seldom above 15m, pr<strong>of</strong>usely branched,<br />

upon <strong>of</strong>ten massive trunks <strong>and</strong> supporting a large number <strong>of</strong> epiphytes like lichens, mosses <strong>and</strong> ferns in addition to<br />

numerous creepers, stragglers <strong>and</strong> on the forest floor several species <strong>of</strong> shrubs <strong>and</strong> herbs.<br />

For some three decades the Sholas have been the focus <strong>of</strong> intense conservation activity in South <strong>India</strong>. “Save our<br />

Sholas” (S.O.S) being the rallying cry <strong>of</strong> the pr<strong>of</strong>essional biologists as well as school students <strong>and</strong> even small traders.<br />

Much <strong>of</strong> this activity, <strong>and</strong> the history <strong>of</strong> forest degradation has been centred around the popular hill resort <strong>of</strong> Kodaikanal,<br />

a sleepy place in the mid 1980’s that has since then undergone massive commercialisation. Despite this growth the<br />

campaigns to conserve <strong>and</strong> restore the Sholas have met with considerable success. It was our chance find <strong>of</strong> Pambar<br />

Shola in 1985 as resident tourists in Vattakanal, <strong>and</strong> a realisation <strong>of</strong> its specialness <strong>and</strong> the need to save it from rapid<br />

destruction that put a halt to our travels <strong>and</strong> launched us into a life <strong>of</strong> conservation <strong>and</strong> a deep association, knowledge<br />

<strong>and</strong> love <strong>of</strong> the plants <strong>of</strong> the Shola grassl<strong>and</strong>s <strong>of</strong> the Southern Western Ghats.<br />

The work we embarked on was all made possible by the formidable Flora <strong>of</strong> the Tamil Nadu Carnatic (1983) <strong>and</strong> the<br />

promise <strong>of</strong> the Flora <strong>of</strong> the Palni Hills (1999) to come authored by Dr. Fr. K.M Matthew. In these huge volumes we not<br />

only found the means to know, but we found the assurance that there was a solid base <strong>of</strong> sound committed people<br />

around us.<br />

It took a few years <strong>of</strong> coming <strong>and</strong> going before we finally founded a tree nursery in the vicinity <strong>of</strong> Pambar Shola. It was<br />

another year or two though before we realised what an extraordinary treasure house <strong>of</strong> plants we found ourselves in the<br />

midst <strong>of</strong>. In the odd 2 sq. km <strong>of</strong> Sholas, ravines <strong>and</strong> rocky grassl<strong>and</strong>s around us many plants could be found that had<br />

passed into extinction elsewhere in the hills. In past decades the western plateau grassl<strong>and</strong>s had supported hundreds <strong>of</strong><br />

plant species but by the end <strong>of</strong> the 1980’s most <strong>of</strong> these grassl<strong>and</strong>s had been put under Pine, Wattle <strong>and</strong> Eucalyptus, <strong>and</strong><br />

many <strong>of</strong> the plants described as common <strong>and</strong> abundant by Dr. K.M. Matthew, had to us become rare <strong>and</strong> threatened;<br />

extinction within the plantations was close to 100%.<br />

Choosing a few plants from this vast catalogue for this article has proven difficult, but the rediscovery <strong>and</strong> cultivation <strong>of</strong><br />

those <strong>of</strong>ficially thought to be extinct has a special meaningfulness. Probably the best example is the Shola tree<br />

Elaeocarpus blascoi, which was discovered only in the 1970’s – a single tree near Kodaikanal that had by the time <strong>of</strong><br />

publication <strong>of</strong> the Flora <strong>of</strong> the Palni Hills in 1999 fallen to the axe. It was somehow extraordinary that we should<br />

rediscover it in our own back yard in 2000, <strong>and</strong> later discover we had unknowingly planted a sapling from a seed <strong>of</strong> this<br />

tree in 1997. Plate 19 shows the photo <strong>of</strong> this plant from its first flowering in 2005.<br />

Restoration was at the heart <strong>of</strong> our work with plants, <strong>and</strong> for that the forest component presented no difficulties,<br />

degraded Shola was there for us to restore so that rare “extinct” species like the tree Psydrax ficiformis <strong>and</strong> the globally<br />

threatened Elaeocarpus recurvatus could be planted in the weed infested degraded areas around Pambar Shola.<br />

The most threatened plants <strong>of</strong> all, nevertheless, were those <strong>of</strong> the grassl<strong>and</strong>s, <strong>and</strong> there was no obvious way <strong>of</strong> reintroducing<br />

these short <strong>of</strong> a systematic restoration <strong>of</strong> their grassl<strong>and</strong> habitat.<br />

Many <strong>of</strong> these plants, however, such as Cotoneaster buxifolius, Coelogyne mossiae <strong>and</strong> Kalanchoe gr<strong>and</strong>iflora make<br />

excellent garden ornamentals, <strong>and</strong> there were plenty <strong>of</strong> people happy to give them a home. The big prize <strong>of</strong> grassl<strong>and</strong><br />

restoration would have to be fought for <strong>and</strong> now more than five years after that struggle began in earnest we (Vattakanal<br />

Conservation Trust) <strong>and</strong> the Forest Department planted our first 1000 grasses together on 9.09.08 in a plot <strong>of</strong> cleared<br />

Wattle with a large <strong>and</strong> beautiful marsh at the centre <strong>of</strong> the restoration. Apart from the desire to restore the complex<br />

diversity <strong>of</strong> the grassl<strong>and</strong>s, issues such as human animal conflict <strong>and</strong> declining water tables under timber plantations<br />

entwined together in this new policy <strong>of</strong> restoration which is still in its pilot stage. Before we can think <strong>of</strong> planting out the<br />

many rare <strong>and</strong> threatened species, we have to make sure that when a plantation coupe is felled alien weeds, most<br />

notably Ageratina adenophora (Eupatorium), do not take over, coupled with planting some <strong>of</strong> the more common<br />

grasses in the Genus Chrysopogon, Themeda, Tripogon <strong>and</strong> Heteropogon to assist the re-grassing process.<br />

We look forward to re-introducing grassl<strong>and</strong> herbs <strong>and</strong> shrubs, among these Exacum wightianum in Gentianaceae <strong>and</strong><br />

Lilium neilgherrense (Plate 19).<br />

Exacum wightianum Arn. (Gentianaceae)<br />

A sub-shrubby herb, usually to a metre in height flowering from June to December. It is reported from a number <strong>of</strong> places<br />

in the Western Ghats but we have not seen it outside the Palni Hills. This plant is not among our <strong>of</strong>ficially listed<br />

threatened species but we have seen its occurrence decline sharply, along with its grassl<strong>and</strong> habitat. It has been seen<br />

over the years to find refuge as a wayside plant, but with the ever increasing numbers <strong>of</strong> self drive tourists taking to the<br />

roads no plant with showy flowers is now safe from being plucked to extinction in this particular kind <strong>of</strong> habitat. We<br />

quickly found in the restoration <strong>of</strong> Pambar Shola that we had to hide from view the most beautiful <strong>of</strong> our herbaceous<br />

plants.<br />

This short lived plant is very difficult to cultivate from its tiny seeds which it produces in great quantities. It does not<br />

tolerate being moved <strong>and</strong> wild plants taken by gardeners always fail. Direct sowing <strong>of</strong> seeds in suitable restored habitat<br />

<strong>of</strong>fers perhaps the best chance <strong>of</strong> halting its decline.

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

This erect unbranched herb with alternate lanceolate leaves can occasionally attain a height <strong>of</strong> 2m <strong>and</strong> sometimes<br />

bear as many as 5 flowers although solitary flowering is most common. Matthew (1996) described the plant as being<br />

common on exposed grassy slopes, but being decimated from over collecting for the showy, scented flowers. Today it<br />

is never seen as Matthew described as all the slopes are under plantation. Now it is most commonly seen surviving<br />

among steep stony fragments <strong>of</strong> l<strong>and</strong>, growing alongside bananas <strong>and</strong> other crops at around 1500 to 1700m. Its<br />

general distribution is the S.W. Ghats <strong>and</strong> the Nilgiris but we have only seen it in the Palnis.<br />

Fortunately, it is an easy plant to reproduce by separating the “flakes” that make up the bulb <strong>of</strong> the plant. Each flake may<br />

produce a flowering plant within 4 or 5 years. For obvious reasons any restoration <strong>of</strong> this plant to the wild will have to be<br />

kept well hidden.<br />

Elaeocarpus blascoi Weibel (Elaerocarpaceae).<br />

A large Shola tree that is endemic to the Palni Hills. There is only one known surviving adult specimen in the wild but we<br />

have planted one along our roadside <strong>and</strong> have several saplings. The tree flowers in June <strong>and</strong> sets seed by October.<br />

Unfortunately, our mother tree is located beside a steep stream that runs down to the plains <strong>and</strong> most seed gets washed<br />

down in the monsoon.<br />

Ceropegia thwaitesii Hook. (Asclepiadaceae)<br />

Another plant <strong>of</strong> the wayside, described by Matthew as occasional above 1800m, is now considered to be vulnerable<br />

(Nayar & Sastry 1987-88), is Ceropegia thwaitesii, an extensive twiner in the family Asclepiadaceae. We have only ever<br />

found one clump <strong>of</strong> this plant on the edge <strong>of</strong> our own Pambar Shola at 2100m. The genus is much favoured by<br />

horticulturalists on account <strong>of</strong> their interesting lantern like flowers. At 5cm C. thwaitesii has the largest flower <strong>of</strong> the six<br />

species found in the Palni Hills. It is fortunately very easy to reproduce from stem cuttings. The plant is also found in Sri<br />

Lanka <strong>and</strong> the far Southern Western Ghats <strong>of</strong> Tinnevely district <strong>of</strong> Tamil Nadu. Some web sites we have found falsely<br />

claim the plant to be a Pambar endemic.<br />

Hoya wightii Hook. f. ssp. palniensis K.T. Matthew (Asclepiadaceae)<br />

Staying in the same family (Asclepiadaceae) we should finish with a true Pambar Shola endemic. This sub species<br />

was only described in 1992. Another genus favoured by horticulturalists on account <strong>of</strong> its “wax” flowers. The plant has<br />

thick, coriaceous, elliptic leaves on stems that trail over massive boulders that lie at the bottom <strong>of</strong> Pambar ravine. There<br />

was some doubt as to whether the plant would survive in the wild as a seed bearing follicle had not been seen since<br />

1914. This was until late 2007 when one <strong>of</strong> our plants raised from a stem cutting bore two follicles which successfully<br />

produced seedlings in August <strong>of</strong> this year.<br />

Since the Cenozoic uplift, the vegetation <strong>of</strong> Western Ghats has witnessed drastic transformation from humid tropical<br />

Malaysian <strong>and</strong> Afro-tropical types to present form <strong>and</strong> composition. The formation <strong>of</strong> the lava plateau namely Deccan<br />

Trap <strong>and</strong> the geodynamic events such as continental drift <strong>and</strong> Pleistocene glaciation accelerated the formation <strong>of</strong> new<br />

<strong>and</strong> unique microclimates in the region (Nayar 1996). The massive depopulation <strong>of</strong> vegetation occurred during the<br />

movements <strong>of</strong> <strong>India</strong>n plate towards northward to duck on to Laurasia (Raven & Axelrod 1974) making this l<strong>and</strong>mass a<br />

unique cradle with numerous micro-habitats. These habitats were gradually re-vegetated giving rise to present day<br />

physiognomic types some <strong>of</strong> which are unique to these ranges such as Shola-Grassl<strong>and</strong> complex, which represent<br />

the juxtaposition <strong>of</strong> distinct ecosystems <strong>and</strong> abrupt changes in habitat types.<br />

The genus Strobilanthes (Acanthaceae), an old world taxon having over 300 species within South / South-east Asia,<br />

has speciated <strong>and</strong> diversified in the hill ranges <strong>of</strong> Western Ghats. This genus has over half <strong>of</strong> world’s species in <strong>India</strong>.<br />

The hill ranges <strong>of</strong> peninsular <strong>India</strong> have 59 species. The most popular character <strong>of</strong> Strobilanthes is its monocarpic<br />

nature <strong>and</strong> they flower after a long period <strong>of</strong> vegetative growth ranging from 1-15 years <strong>and</strong> some rare species produce<br />

flowers even after 35 years. The Neelgiri hills <strong>of</strong> south <strong>India</strong> (Blue Mountains) are named after Strobilanthes kunthianus,<br />

locally known as ‘Neelakkurinji’ that flowers in pr<strong>of</strong>usion once in 12 years. Likewise a number <strong>of</strong> other species within<br />

this group exhibit the unique features <strong>of</strong> habitats <strong>and</strong> phytogeography which have little been investigated. This article<br />

throws some light on the diversity, distribution <strong>and</strong> habitat specificity <strong>of</strong> this genus in the High Ranges <strong>of</strong> Kerala, Western<br />

Ghats.<br />

The High Ranges <strong>of</strong> Kerala<br />

The southern Western Ghats i.e., the hill tops south <strong>of</strong> Palakkad Gap in the state <strong>of</strong> Kerala (Idukki district), represent<br />

highly dissected valleys <strong>and</strong> camel-hump peaks <strong>and</strong> unique habitats. These ranges include some <strong>of</strong> the tallest peaks<br />

in Peninsular <strong>India</strong>, highest being the famous ‘elephant head’ or Anamudi peak (2690m). The lower parts <strong>of</strong> these<br />

ranges are highly productive <strong>and</strong> therefore, for last two centuries these tracts have been encroached for commercial<br />

plantations. Presently three categories <strong>of</strong> l<strong>and</strong> use can be seen this area (Moench 1991). These are: (i) Protected<br />

Areas (PAs), (ii) Tea plantations, <strong>and</strong> (iii) areas <strong>of</strong> extensive cardamom cultivation. The PAs include Periyar Tiger<br />

Reserve, Eravikulam National Park, Chinnar <strong>and</strong> Idukki Wildlife Sanctuaries <strong>and</strong> Thattekkad Bird Sanctuary. In addition<br />

to these five PAs, there are 35 tea estates spread over Munnar <strong>and</strong> Peermade <strong>of</strong> the High Ranges (Anonymous 1970).<br />

The rest <strong>of</strong> the High Ranges, were opened since early 1800s to establish cardamom cultivation. This area is known as<br />

Cardamom Hill Reserve (CHR). It was reserved in 1897 as Government Reserved Forest <strong>and</strong> had an area <strong>of</strong> 870 km 2<br />

that falls under Udumbanchola Panchayat (old) <strong>of</strong> Idukki District (Anonymous 1978, Nair 1991). From early 1800s, the<br />

area has undergone severe deforestation due to extensive planting <strong>of</strong> cash crops, especially cardamom (Anonymous<br />

1984). The major vegetation types include Tropical Wet Evergreen, Tropical Semi-evergreen, Montane Shola <strong>and</strong><br />

Grassl<strong>and</strong>s (Champion & Seth 1968, Ch<strong>and</strong>rasekharan 1962).<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Diversity <strong>and</strong> Distribution <strong>of</strong> Strobilanthes in the High Ranges <strong>of</strong> Kerala<br />

The hilltops <strong>and</strong> understory <strong>of</strong> evergreen forests in the High ranges <strong>of</strong> Kerala <strong>and</strong> other parts <strong>of</strong> Western Ghats are are<br />

well known for the Strobilanthes thickets (Plates 20A & 20B). The evident domination <strong>of</strong> Acanthaceae in the shrubby<br />

layers <strong>of</strong> evergreen forests <strong>of</strong> Peninsular <strong>India</strong> is mainly due to diversity <strong>of</strong> genus Strobilanthes. There are altogether 43<br />

species <strong>of</strong> Strobilanthes known from the state <strong>of</strong> Kerala. Of these, 38 are endemic to Peninsular <strong>India</strong> (Sasidharan<br />

2000). Three species are endemic to Kerala viz., S. dupeni, S. homotropus <strong>and</strong> S. virendrakumarana . Two species, S.<br />

homotropus <strong>and</strong> S. <strong>and</strong>ersonii are exclusive endemic Idukki District. Strobilanthes <strong>and</strong>ersonii is so far not known from<br />

Kerala <strong>and</strong> it is the first report <strong>of</strong> its occurrence in the state. Almost all the species (40) <strong>of</strong> Strobilanthes are found in the<br />

High ranges. Fortunately, most <strong>of</strong> them occur within the existing PAs. For example, 17 species <strong>and</strong> one sub-species<br />

were known to occur in Eravikulam NP according to earlier researchers (Biju 2004). The author has added five more<br />

species from Eravikulam which are being reported here. These are S. <strong>and</strong>ersonii, S. neoasper, S. urceolaris, S.<br />

anamallaica <strong>and</strong> S. barbatus. Anamudi Chola NP harbours 18 species (Kishore 2004) while Periyar TR has as many<br />

as 27 species. Interestingly only one species (Strobilanthes cuspidatus) has been reported from Chinnar WS so far.<br />

More studies are required within this <strong>and</strong> adjacent sanctuaries. The species <strong>of</strong> Strobilanthes in high ranges (40) are<br />

as follows:<br />

1. Strobilanthes amabilis Clarke: Endemic to Southern Western Ghats. Rare along shola margins. Flowering<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Based on the distribution <strong>and</strong> diversity <strong>of</strong> this genus, it can be ascertained that the High ranges <strong>of</strong> Kerala is a hotspot <strong>of</strong><br />

endemic Strobilanthes. Possible reasons for species explosion <strong>and</strong> endemism could be geographical isolation <strong>of</strong><br />

many highl<strong>and</strong> valleys <strong>and</strong> gorges coupled with compression <strong>of</strong> altitudinal <strong>and</strong> eco-climatic zones within small<br />

geographical area. The High Ranges range between 700 <strong>and</strong> 2690m asl <strong>and</strong> there are many hills <strong>and</strong> peaks above<br />

2000 m. Only a few species are found to occur below 500m namely S. barbatus, S. warrensis, S. heyneanus, S.<br />

rubicundus which may reach up to 1400m asl. Likewise, some species such as S. homotropus, S. violaceous, S.<br />

zenkerianus, S. <strong>and</strong>ersonii, S. gracilis, S. wightianus, S. urceolaris, S. foliosus, etc. are seen exclusively above 2000m<br />

asl. S. <strong>and</strong>ersonii <strong>and</strong> S. zenkerianus are present in certain pockets <strong>of</strong> shola forests only in Eravikulam NP. The altitude<br />

specific distribution <strong>of</strong> these 40 species can be attributed to recent isolation <strong>of</strong> the various populations <strong>of</strong> the ancestral<br />

stock <strong>and</strong> speciation <strong>of</strong> these taxa as neoendemics. The evolution <strong>of</strong> grassl<strong>and</strong> specific species like S. kunthianus <strong>and</strong><br />

S. sessilis are still more recent as the evolution <strong>of</strong> grassl<strong>and</strong>s in South <strong>India</strong>n hills are thought as comparatively recent<br />

(Subhash Ch<strong>and</strong>ran 1997). But the distribution <strong>of</strong> S. kunthianus is wider than many other species which are with<br />

narrower distribution. It may be noted that habitat destruction may not be the only cause for the narrow distribution <strong>of</strong><br />

Strobilanthes spp. Micro-habitats specificity may also contribute towards narrow distribution. Cladistics <strong>and</strong> adaptations<br />

<strong>of</strong> ancestral stock within the group may through some light on the evolutionary divergence. It is interesting also to note<br />

that several species (around 50%) are vagile <strong>and</strong> do not disperse far from their habitats.<br />

Occurrence <strong>of</strong> largest number <strong>of</strong> Strobilanthes species (27) within Periyar TR can be attributed to the large tract <strong>of</strong><br />

evergreen forests <strong>and</strong> wide ranges <strong>of</strong> altitudinal variation (200 to 2016m asl). Species like S. tristis, S. warrensis, S.<br />

rubicundus, S. pulneyensis, S. micranthes, S. luridus, S. homotropus, S. heyneanus, S. decurrens, S. ciliatus, S.<br />

asperrimus, S. anceps, S. virendrakumarana, S. ixiocephalus, S. <strong>and</strong>ersonii, S. barbatus <strong>and</strong> S. dupenii prefer evergreen<br />

habitats. Strobilanthes foliosus, S. wightianus, S. urceolaris, S. caudatus, S. violacea, S. zenkerianus <strong>and</strong> S. gracilis<br />

prefer margins <strong>of</strong> evergreen shola forests.<br />

The monocarpic nature <strong>and</strong> gregarious flowering (species specific periodicity) makes the biology <strong>of</strong> this species most<br />

interesting. The periodicity <strong>of</strong> flowering varies from annual to 16 years. Species such as S. anamallaica, S. asperrimus,<br />

S. ciliatus, S. heyneanus, S. pulneyensis, S. sessilis, S. urceolaris <strong>and</strong> S. wightianus produce flowers every year while<br />

S. amabilis, S. gracilis, S. homotropus, S. jeyporensis, S. kunthiana, S. micranthus, S. perrottetianus, S. violceus <strong>and</strong> S.<br />

zenkarianus flower after more than 10 years <strong>of</strong> vegetative growth. There are six species which flower after seven years<br />

<strong>of</strong> growth. Except for certain well known popular species like S. kunthianus, S. carvi, etc. the flowering periodicity can<br />

be studied only through tracing the herbarium collection. But it is not always correct. There are sporadic flowering for<br />

some species which may also be included in the herbarium collection. Also, in certain species there is more than one<br />

population in the same locality. Best example <strong>of</strong> this is S. kunthianus, which is with three different populations in<br />

Munnar (a major centre <strong>of</strong> S. kunthianus distribution). One population <strong>of</strong> this species is located on one side <strong>of</strong> a hill <strong>and</strong><br />

the second is on the other side. During the last 8 years, there were three massive blooming <strong>of</strong> this shrub whose<br />

flowering periodicity is once in 12 years. This may due to the delay <strong>of</strong> seed germination due to some reason in earlier<br />

seasons. The species with long flowering periodicity <strong>and</strong> monocarpic nature is also a potential cause for their rarity. In<br />

many local floras there are some unidentified or misidentified collections <strong>of</strong> Strobilanthes which were collected during<br />

their vegetative stage. So at least some rare species were left unidentified in many local floras <strong>and</strong> the presence <strong>of</strong> them<br />

were not documented.<br />

The mass flowering is a usual feature <strong>of</strong> Strobilanthes spp. The process has been well documented in case <strong>of</strong> S.<br />

kunthianus. During the last flowering (year 2008) in Eravikulam NP, flowering started at Rajamala (southernmost part),<br />

moved northward <strong>and</strong> the entire NP was covered with the gregarious flowering. Mass flowering <strong>of</strong> S. homotropus <strong>and</strong>

S. gracilis makes the entire shola as a flowering forest. When we analyze the last flowering <strong>of</strong> Strobilanthes spp. in the<br />

High Ranges it is again miraculous. More than 25 different species flowered simultaneously <strong>and</strong> the entire High<br />

Ranges became the paradise <strong>of</strong> Strobilanthes. One wonders how much <strong>of</strong> intermixing <strong>and</strong> hybridization goes on when<br />

25 different species flower synchronously.<br />

Conservation <strong>and</strong> management implications <strong>of</strong> mass flowering<br />

Ecologically mass blooming <strong>of</strong> Strobilanthes <strong>and</strong> synchronous flowering <strong>of</strong> various species can have several<br />

consequences, which are not understood fully. The dying out <strong>of</strong> these species subsequent to flowering produces<br />

enormous combustible material within <strong>and</strong> around shola forests which are very susceptible to forest fires. Most <strong>of</strong> the<br />

25 species flowered during 2008 are shola specific <strong>and</strong> they occupied more than 90 percent <strong>of</strong> shrubby regime. So the<br />

entire shrubby stratum <strong>of</strong> shola forests has become vulnerable to fire. The seeds <strong>of</strong> these species are just liberated into<br />

soil <strong>and</strong> some <strong>of</strong> them are at the state <strong>of</strong> maturing. Occurrences <strong>of</strong> fire in these shola forests will definitely burn the<br />

seeds <strong>and</strong> hence it may cause extinction <strong>of</strong> narrow endemics. As a strategy for the future development <strong>of</strong> Idukki District<br />

the tourism industry (Anonymous 1998) is much significant. In this context the blooming <strong>of</strong> Strobilanthes (Kurinji) is an<br />

item for revenue. It is estimated that the last mass blooming <strong>of</strong> Strobilanthes kunthianus (Neelakkurinji) had generated<br />

a revenue <strong>of</strong> around Rs. 2000 crores within three months. Sadly, very little <strong>of</strong> this money is ploughed back for effective<br />

conservation <strong>and</strong> management <strong>of</strong> these species.<br />

21.0 Rocky Outcrops as <strong>Special</strong> <strong>Habitats</strong> in<br />

North Western Ghats, Maharashtra<br />

“Rock outcrops” is the term used for habitats where portions <strong>of</strong> freely exposed bedrock protrude above the soil level due<br />

to natural reasons. Rocks exposed due to human activities such as deforestation are not included in this habitat<br />

category. Cliffs, isolated hills <strong>and</strong> platforms <strong>of</strong> rocks formed due to l<strong>and</strong>scape level activities <strong>of</strong> weathering are the types<br />

<strong>of</strong> outcrops seen commonly in <strong>India</strong>. Well known rock outcrops habitats in the world are inselbergs, barrens, cedar<br />

glades, cliffs, serpentine, ultramafic, limestone <strong>and</strong> gypsum outcrops. Each <strong>of</strong> which is known to harbour highly<br />

specialized vegetation rich in habitat specific <strong>and</strong> endemic plants.<br />

Rock outcrop habitats are generally <strong>of</strong> small extent within a region <strong>and</strong> present particular habitat limitations e.g.,<br />

exposure to sun <strong>and</strong> lack <strong>of</strong> soil. The microenvironment at the rock surface ranges from very hot <strong>and</strong> arid in dry season<br />

to water logged in the wet season. Hence edaphically controlled herbaceous plant communities are characteristic <strong>of</strong><br />

rock outcrops. On an outcrop a variety <strong>of</strong> microhabitat types have been recognized such as seasonal rock pools,<br />

ephemeral flush communities, shallow depressions, boulders, crevices, etc. Owing to the diversity <strong>of</strong> microhabitats,<br />

rock outcrop are actually “habitat complexes” sheltering a diversity <strong>of</strong> plant groups ranging from succulents to hydrophytes<br />

within a relatively small area. Extreme microenvironmental conditions present on the outcrops differ widely from the<br />

surrounding mesic areas <strong>and</strong> hence they function as terrestrial habitat isl<strong>and</strong>s. In many regions <strong>of</strong> Africa, America <strong>and</strong><br />

Australia, it has resulted in the formation <strong>of</strong> narrowly endemic species which are adapted to the microclimatic conditions<br />

<strong>of</strong> the outcrops <strong>and</strong> cannot thrive elsewhere.<br />

In <strong>India</strong>, the habitat is represented in many ways. Large monolithic inselbergs <strong>and</strong> koppjes are common in South <strong>India</strong>.<br />

Cliffs are dominant outcrop type in the mountainous regions. Rocky plateaus <strong>of</strong> basalt <strong>and</strong> laterite present in Western<br />

Maharashtra (between 16 0 -19 0 N latitude), are <strong>of</strong> high botanical value due to presence <strong>of</strong> endemic plants (Plates 21A<br />

& 21B). In spite <strong>of</strong> western Maharashtra being floristically well studied <strong>and</strong> rich in endemic species, scant information<br />

is available about the general ecology <strong>and</strong> diversity <strong>of</strong> vegetation <strong>of</strong> these outcrops.<br />

The lateritic outcrops are indurated rocky plateaus <strong>of</strong> laterite, known as duricrusts or ferricretes. These are formed<br />

around 65m years ago, due to chemical leaching <strong>of</strong> the parent rock in high rainfall conditions followed by hardening<br />

leading to formation <strong>of</strong> laterite, a red coloured stone rich in iron <strong>and</strong> aluminium. Lateritic outcrops (known as ‘sadas’ in<br />

Marathi) can be divided into high level laterites located between 800-1200m asl in the Western Ghats <strong>and</strong> low level<br />

laterites located below 100m asl in the Konkan region. They occur between 16 0 -18 0 N in Maharashtra. The outcrops<br />

<strong>of</strong> basalt are exposed on flat topped hills <strong>of</strong> the northern Western Ghats <strong>and</strong> are more common at the northern tip <strong>of</strong> the<br />

Western Ghats, between 18 0 - 21 0 N. All the outcrops are widely separated from each other by highly weathered<br />

l<strong>and</strong>scape, predominantly covered by woody vegetation, <strong>and</strong> thus exist as “terrestrial isl<strong>and</strong> habitats”.<br />

Soil formation on the outcrops is extremely slow. Soil depth varies from a few centimeters on flat areas to about a meter<br />

in deep cracks <strong>and</strong> depressions. It is s<strong>and</strong>y to s<strong>and</strong>y loam in texture, highly acidic <strong>and</strong> poor in phosphates. In the dry<br />

period, the temperature <strong>of</strong> exposed rock surface is very high (maximum recorded 58 0 C) <strong>and</strong> humidity is very low<br />

(lowest recorded 14%). In the monsoon, conditions go to other extreme when the rains are continuous <strong>and</strong> heavy from<br />

July to September, leading to formation <strong>of</strong> ephemeral wetl<strong>and</strong>s. Scarcity <strong>of</strong> soil <strong>and</strong> extremes <strong>of</strong> microclimate are<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

unfavourable for the growth <strong>of</strong> perennial vegetation. Hence, vegetation dominated by annuals thrives on outcrops only<br />

in moist conditions. Following vegetation types can be categorized on these outcrops. The microhabitat categories<br />

follow Porembski et al. (1998) with some modifications.<br />

Vegetation <strong>of</strong> rock surfaces<br />

Cryptogamic vegetation <strong>of</strong> rock surfaces [R] :<br />

Exposed rock surfaces on laterite as well as basalt are completely covered by cyanobacterial crust <strong>and</strong> some crustose<br />

<strong>and</strong> foliose lichens. Immediately after the onset <strong>of</strong> monsoon, the rocks become slippery due to the slimy sheaths <strong>of</strong> the<br />

cyanobacteria.<br />

Cryptogamic vegetation <strong>of</strong> boulders [B] :<br />

Boulders <strong>of</strong> different sizes up to a meter in height occur <strong>of</strong>ten on the outcrop surfaces. On some lateritic plateaus, the<br />

entire surface is covered by loose boulders which make it look like rock field. The boulders are also covered by<br />

cyanobacterial crust, <strong>and</strong> have other species according to the available surface, crags <strong>and</strong> height <strong>of</strong> the boulders.<br />

Moss cushions <strong>and</strong> ferns including desiccation tolerant Cheilanthes sp. are frequent on the boulders. Lithophytic<br />

orchids such as Eria find this a suitable place for growth.<br />

Vegetation <strong>of</strong> rock crevices [CR] :<br />

Crevices in rocks provide opportunities for establishment <strong>of</strong> the plants. Depending upon the depth <strong>and</strong> width, they can<br />

be small or large. Small crevices are very common on the outcrops <strong>and</strong> provide safe growing sites for mosses, ferns<br />

<strong>and</strong> some angiosperms like Flemingia neilgheriensis.<br />

Vegetation <strong>of</strong> depressions:<br />

Vegetation <strong>of</strong> ephemeral pools [SRP] :<br />

c1.1. Shallow pools are commonly formed in places where water accumulates after flowing over a gently sloping area.<br />

They have gently sloping sides, little accumulated soil at bottom <strong>and</strong> about 2-5cm depth <strong>of</strong> water. Shallow pools on<br />

lateritic plateaus <strong>of</strong> the Western Ghats are habitats <strong>of</strong> rare Ericaulon tuberiferum <strong>and</strong> Aponogeton saterensis.<br />

c1.2. Deep pools are more common on the basaltic outcrops. They form in large potholes, with well defined <strong>and</strong><br />

almost vertical rocky edges, have 10cm or more water depth <strong>and</strong> <strong>of</strong>ten have a few cm <strong>of</strong> soil accumulated at the bottom<br />

<strong>of</strong> the pothole. Some <strong>of</strong> the deep pools can be more than 1m deep <strong>and</strong> retain some water in the deepest part almost<br />

through the year.<br />

Soil filled depressions: Soil filled depressions occur where rock is relatively flat <strong>and</strong> soil <strong>and</strong> humus have accumulated<br />

over the years.<br />

Ephemeral flush vegetation [EFV] :<br />

The term ephemeral flush vegetation (EFV) is a special type <strong>of</strong> vegetation that grows on rocky areas where water slowly<br />

seeps through soil. During the rainy season, EFV has a meadow-like physiognomic appearance whereas the dry<br />

season aspect is almost desolate with the bare exposed soil covered with sparse desiccated plant remnants. It is the


most interesting community on outcrops <strong>and</strong> includes high percentage <strong>of</strong> insectivorous Utricularia together with<br />

Eriocaulon spp.<br />

Seasonality <strong>of</strong> the vegetation is very marked on the outcrops. The rocky plateaus present an entirely dry almost barren<br />

appearance during the summer <strong>and</strong> winter. However, with the first monsoon showers, the plateaus become water<br />

logged leading to a sudden greening <strong>of</strong> the rocks. Although the actual species composition varies with the type <strong>of</strong><br />

outcrop <strong>and</strong> its location, the vegetation follows a similar pattern viz. vegetative growth <strong>of</strong> flora <strong>and</strong> flowering <strong>of</strong> geophytes<br />

in early monsoon, followed by gregarious flowering <strong>of</strong> ephemerals in late monsoon followed by flowering <strong>of</strong> grasses<br />

signifying the end <strong>of</strong> vegetation cycle on the outcrops in this region. Very few perennials are seen persisting through<br />

summer <strong>and</strong> winter. A general description <strong>of</strong> vegetation is provided here.<br />

In the early monsoon, during June <strong>and</strong> July Poaceae members such as Glyphochloa forficulata, Isachne lisboae are<br />

abundant <strong>and</strong> dominant together with Fimbristylis tenera (Cyperaceae) <strong>and</strong> Eriocaulon spp. although all are in vegetative<br />

conditions. This phase is marked by the flowering <strong>of</strong> Hypoxis aurea, Iphigenia stellata. In August few species such as<br />

Dipcadi montanum, Habenaria heyneana, H. panchganiensis, Swertia minor reach flowering peak.<br />

In the late monsoon phase in September, several species <strong>of</strong> early phases reach flowering peak. Most dominant are<br />

Fimbristylis tenera together with Poaceae members. Hedyotis stocksii, Rotala sp., Flemingia neilgheriensis , Jansenella<br />

griffithiana Coelachne minuta, Indopoa paupercula are most abundant at this time. This phase also shows mass<br />

blooming <strong>of</strong> Utricularia <strong>and</strong> Eriocaulon spp. Plant diversity <strong>and</strong> richness is highest in this phase (Highest recorded<br />

H’=4.417, N=47 in the Western Ghats outcrops). In one monsoon, up to 23 species were recorded in a single 1X1m<br />

quadrat indicating very high species richness.<br />

In the post monsoon phase, abundance <strong>and</strong> dominance <strong>of</strong> Poaceae reaches peak with some grasses such as<br />

Glyphochloa forficulata almost singly dominant in most quadrats. Sub dominants include endemic Dimeria spp.<br />

Ischaemum spp. <strong>and</strong> Dichanthium spp. mostly in the fruiting stages. During winter the lateritic outcrops are parched dry<br />

with the exception <strong>of</strong> a few individuals <strong>of</strong> Blumea malcolmii, B. oxyodonta, Crotalaria vestita, etc. In locally moist areas<br />

such as drying rock pools, Pogostemon deccanensis <strong>and</strong> Rotala densiflora remain. Indig<strong>of</strong>era dalzellii that occurs<br />

commonly on the lateritic plateaus starts flowering in May with pre-monsoon showers <strong>and</strong> continues to flower throughout<br />

the monsoon, reaching fruiting stage in October.<br />

Abundance <strong>and</strong> dominance <strong>of</strong> endemics is an important feature <strong>of</strong> this habitat. Based upon primary <strong>and</strong> secondary<br />

data, about 150 endemic species have been recorded to occur on rocky plateaus in the Northern Western Ghats <strong>and</strong><br />

Konkan areas. Many <strong>of</strong> these endemics (viz. Aponogeton satarensis, Ceropegia jainii) show highly restricted geographical<br />

distribution <strong>and</strong> are specific to microhabitats. Forty <strong>of</strong> these are listed as threatened according to IUCN criteria by the<br />

Botanical Survey <strong>of</strong> <strong>India</strong>. Monotypic Indopoa paupercula <strong>and</strong> Bhidea burnsiana are restricted to the rocky areas in<br />

general <strong>and</strong> are abundant on the rock outcrops. Dimeria woodrowii is exclusively seen on the low level lateritic<br />

plateaus. Others like Ceropegia, Hedyotis have obligate endemic species on ferricretes in addition to several related<br />

species in the surrounding shrub savannahs, forests <strong>and</strong> wetl<strong>and</strong>s. Highly specialized ephemeral flush vegetation <strong>and</strong><br />

abundance <strong>of</strong> endemic species seen no where else in world, makes outcrop vegetation in Maharashtra globally<br />

unique.<br />

Details <strong>of</strong> some important threatened plants seen on outcrops are provided here:<br />

North Western Ghats, Maharashtra<br />

This is a small annual <strong>of</strong> Asteraceae which grows on basaltic outcrops in shallow depressions. Secondarily it is also<br />

seen growing along field edges <strong>and</strong> in areas <strong>of</strong> moist soil. It has a small rosette <strong>of</strong> leaves through which emerges a long<br />

stalk about 10-15 cm high bearing bunch golden yellow coloured capitula. Though small in size the herbs spread over<br />

large areas <strong>and</strong> bloom en masse in September, imparting golden yellow colour to entire l<strong>and</strong>scape. The species is<br />

found only on basaltic outcrops atop the Western Ghats, in Nasik <strong>and</strong> Pune districts. Though locally abundant, it is<br />

threatened by changes in l<strong>and</strong> use such as conversion <strong>of</strong> outcrops in agricultural areas, overgrazing <strong>and</strong> fires which<br />

change the species composition. It is necessary to prevent these activities to conserve this beautiful species.<br />

Habenaria panchganiensis : Critically endangered<br />

This beautiful ground orchid grows mostly on lateritic plateaus at 1000-1200mASL. A cluster <strong>of</strong> radical leaves emerge<br />

from the bulb during heavy rainfall <strong>of</strong> July. The flowers are bright white <strong>and</strong> bloom for about two weeks between July <strong>and</strong><br />

August. Locally the populations are small about 2-3 individuals per 5X5 square meters. The populations are seriously<br />

threatened by conversion <strong>of</strong> the outcrops into entertainment areas for monsoon tourism. In addition mining for bauxite<br />

is seriously threatening the habitat. It is necessary to provide special protection from trampling tourists <strong>and</strong> also develop<br />

ex situ conservation techniques for this species.<br />

Aponogeton satarensis : Endangered<br />

This tiny geophyte grows in shallow seasonal rock pools on lateritic plateaus at 1000-1200mASL. A short stalk <strong>and</strong> few<br />

leaves emerge above water. The inflorescence stalk is bifurcated, with characteristic Y-shape appearance, bearing<br />

tiny pink flowers during July, August. It is known from only a few localities so far <strong>and</strong> has small populations. These sites<br />

are threatened by l<strong>and</strong>scape conversion by mining, tourism development <strong>and</strong> windmill farms leading to slow degradation<br />

<strong>of</strong> the microhabitats. It can be conserved by protecting the sites <strong>and</strong> also by ex situ conservation in shallow aquatic<br />

gardens.<br />

Euphorbia panchganiensis : endangered<br />

This geophyte has a large underground rhizome which remains dormant for almost 7 months. The inflorescence <strong>of</strong><br />

bright red colour emerges above ground during summer (March-April). The radicle leaves appear as rosettes during<br />

monsoon after the fruiting <strong>and</strong> dispersal <strong>of</strong> seed is over. Locally the populations <strong>of</strong> this species are moderate sized, but<br />

the sites are heavily grazed, <strong>and</strong> trampled. Summer fires set by people are highly disturbing to the outcrop vegetation,<br />

<strong>and</strong> though this species survives through it, the dispersal becomes limited. It is necessary to develop ex situ as well as<br />

in situ measures for its conservation.<br />

Dipcadi concanense : Critically endangered<br />

This is one <strong>of</strong> the most beautiful ground lilies which grow during the monsoon on lateritic plateaus <strong>of</strong> Konkan. The<br />

species was first recorded about a century ago from Malvan, but has now vanished almost completely through its<br />

range. It still survives on the extensive plateau <strong>of</strong> Ratnagiri town, sometimes growing in the backyards <strong>of</strong> houses. A few<br />

more localities are also known from the same area <strong>and</strong> Goa. The underground bulb gives out few narrow linear leaves<br />

<strong>and</strong> the flowering scape is tall, about 30cm tall <strong>and</strong> bears one or two long tubular flowers abt 4cm long <strong>and</strong> <strong>of</strong> purest<br />

white. The site in Ratnagiri area is being converted for housing <strong>and</strong> is proposed MIDC area, threatening the large<br />

population there. Ex situ conservation is thus absolutely necessary for this ornamental species.<br />

The rock outcrops also support insects, fish, amphibians, reptiles <strong>and</strong> birds which have adapted to live in the stressful<br />

environment. Small mammals like rodents feed on underground parts <strong>of</strong> the vegetation. Bats inhabit underground<br />

lateritic caves. During the survey, activity <strong>of</strong> large mammals such as gaur, leopards was <strong>of</strong>ten seen on outcrops in<br />

Protected Areas. Recently new species <strong>of</strong> caecilians have been identified on lateritic outcrops.

Rock outcrops are important as grazing l<strong>and</strong>s for surrounding villages. The shrines <strong>of</strong> deities worshipped by shepherds<br />

<strong>and</strong> places <strong>of</strong> ancestral worship on these outcrops have a special socio-cultural value for local communities. The<br />

rocky plateaus also serve as watershed areas, <strong>and</strong> support large ponds or have perennial water sources along the<br />

edges which are extremely important for local people as well as livestock.<br />

There is however, a serious lack <strong>of</strong> awareness in society regarding the biological, social <strong>and</strong> cultural importance <strong>of</strong><br />

rock outcrop habitats. The dry physical appearance has misled government departments to classify these as wastel<strong>and</strong>s.<br />

This has led to disastrous results as many activities have been allowed on the outcrops without adequate Ecological<br />

Impact Assessments. Mining for bauxite has led to destruction <strong>of</strong> prime habitats in Kolhapur. Ferricretes in Konkan are<br />

converted into mango orchards. Extensive rocky plateaus in Satara district have been converted to windmill farms,<br />

causing a slow degradation <strong>of</strong> vegetation by invasion <strong>of</strong> weeds, changes in drainage pattern <strong>and</strong> fragmentation by<br />

roads <strong>and</strong> fencing. Rocky plateaus at Panchgani <strong>and</strong> Kas, known for exceptional natural beauty are under threat from<br />

growing tourism, insensitive to the fragility <strong>of</strong> their environment. Only those outcrops which are present within wildlife<br />

sanctuary areas <strong>of</strong> Ch<strong>and</strong>oli, Koyana, Radhanagari <strong>and</strong> Dajipur receive some protection. However, they have not<br />

received any special locale specific importance. It is thus necessary to take immediate steps towards the preservation<br />

<strong>of</strong> these unique habitats both within <strong>and</strong> outside PAs.<br />

Suggested measures:<br />

• Limiting destructive activities such as mining, plantation, tourism, constructions <strong>and</strong> burning on plateaus<br />

• Enhanced protection <strong>of</strong> rock outcrops within existing protected areas <strong>and</strong> protection <strong>of</strong> additional representative<br />

sites to complement currently protected outcrops<br />

Complete assessment <strong>of</strong> the floral <strong>and</strong> faunal richness <strong>of</strong> the habitat including those in the Reserved Forests <strong>and</strong><br />

revenue l<strong>and</strong>s<br />

• Awareness generation about the importance <strong>of</strong> preserving these habitats<br />

In addition to this, it is extremely necessary for researchers, environmental managers <strong>and</strong> others to underst<strong>and</strong> the<br />

special nature <strong>and</strong> uniqueness <strong>of</strong> rock outcrop habitats <strong>and</strong> their global conservation significance.<br />

The eastern Vidarbha in Maharashtra- especially the Gadchiroli <strong>and</strong> Gondia districts, forms part <strong>of</strong> biogeographic<br />

province 6B i.e., Central Plateau (Rodgers & Panwar 1988). This province is contiguous with southern flanks <strong>of</strong><br />

Balaghat (Madhya Pradesh; MP), Chhattisgarh, <strong>and</strong> northern districts <strong>of</strong> Andhra Pradesh (AP) <strong>and</strong> more or less uniform<br />

in terms <strong>of</strong> floral diversity, physiography, geology <strong>and</strong> zoogeography. The soil is s<strong>and</strong>y to s<strong>and</strong>y-loam in texture <strong>and</strong><br />

reddish in colour. Mean annual rainfall is about 150cm. The boundaries <strong>of</strong> biogeographic provinces i.e., Eastern<br />

Plateau (6B2) <strong>and</strong> Eastern Highl<strong>and</strong>s (6C2) are not very sharp <strong>and</strong> they inter-grade into each other. Interestingly the<br />

recent physiographic map adopted by the Forest Survey <strong>of</strong> <strong>India</strong> also classifies this region into three zones viz., North<br />

Deccan, East Deccan <strong>and</strong> South Deccan by apparently giving more weightage to the political boundary between<br />

Maharashtra <strong>and</strong> Chhattisgarh. The entire area forms the South-Western <strong>and</strong> Westernmost part <strong>of</strong> historical<br />

D<strong>and</strong>akaranya region. This region extends up to North- Eastern Ghats.<br />

Vidarbha – D<strong>and</strong>akaranya transition harbours some <strong>of</strong> the charismatic wildlife species <strong>of</strong> <strong>India</strong> including the tiger<br />

(Panthera tigris), wild buffalo (Bubalus arnee) <strong>and</strong> chousinga (Tetraceros quadricornis). There is high diversity <strong>of</strong><br />

butterflies all over the area. All the hill streams above 400m altitude show presence <strong>of</strong> majestic Orange oak leaf butterfly<br />

(Kallima inachus) with remarkably high density (about 40-50 individuals per every 10 m length <strong>of</strong> stream). The Southern<br />

open l<strong>and</strong>s along the Godavari plains have been known for the presence <strong>of</strong> Jerdon’s courser (Rhinoptilus bitorquatus),<br />

the endangered bird while the hill forests form the abode <strong>of</strong> <strong>India</strong>n hill myna (Gracula religiosa ssp. peninsularis) which<br />

is the indicator <strong>of</strong> this habitat. Giant squirrel, Ratufa indica ssp. centralis shows its easternmost distribution in this region<br />

<strong>and</strong> is confined to moist riverine forests.<br />

The floristic account <strong>of</strong> Vidarbha <strong>and</strong> South Chhattisgarh region is known from the works <strong>of</strong> Malhotra & Moorthy<br />

(1971,1992), Moghe (1993), Patil (1991), Verma et al. (1985), Ugemuge (1985), Almeida (1996, 1998), Sharma et al.<br />

(1996) <strong>and</strong> Singh et al. (2000, 2001). This article gives a brief overview <strong>of</strong> the habitat <strong>and</strong> vegetation characteristics in<br />

this tract along with status <strong>of</strong> selected rare <strong>and</strong> locally threatened plant species.<br />

Biophysical Features<br />

The Vidarbha – D<strong>and</strong>akaranya tract falls under Godavari river basin which consists <strong>of</strong> Wainganga, Indravati, Pranhita<br />

sub-basins. This area encompasses the Northern Maikal- Satpura ranges <strong>and</strong> Southern Abujhmarh - Bastar hills with<br />

several deep valleys, minor hill ranges <strong>and</strong> peaks (locally called as metta) <strong>and</strong> lateritic plateaus (locally called as<br />

madum). The other important hill ranges in this l<strong>and</strong>scape include Dongargad, Tipagad-Palasgarh, Borgaon, Wadwi<br />

(Surjagad), Gatta (Damkondawahi), Sirikonda, Aheri, Lakkametta <strong>and</strong> Kolamarka. On eastern side Rajn<strong>and</strong>gaon<br />

plateau <strong>and</strong> Bastar - Bijapur highl<strong>and</strong>s form a part <strong>of</strong> larger Chhattisgarh plateau, flanked by Chhattisgarh plains.<br />

These hill ranges, except Abujhmar, are more or less scattered <strong>and</strong> discontinuous. Several small streams passing<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

through the valleys finally meet the main river <strong>of</strong> the sub-basin. The rainfall starts in late June <strong>and</strong> lasts up to November<br />

in some hilly parts. Summers are relatively cooler in comparison to adjoining plains. Altitude ranges from 250m to<br />

almost 900 m <strong>and</strong> temperature fluctuates from about 3 o C to 47 o C.<br />

Since the area discussed above is situated in the transition zone <strong>of</strong> North Deccan (Eastern Maharashtra), South<br />

Deccan (Telangana) <strong>and</strong> East Deccan (West D<strong>and</strong>akaranya), it shows influence <strong>of</strong> all the elements <strong>and</strong> forest types <strong>of</strong><br />

all adjoining areas. The floristic elements show some affinities with the flora <strong>of</strong> Assam- Bihar, Eastern Ghats, Western<br />

Ghats as well as Central region. Sal (Shorea robusta) is confined to the eastern part <strong>of</strong> the region (Rajnadgaon-<br />

Rengakhar) while best quality teak forests (C P Teak) flourishes towards West in the places like Sironcha <strong>and</strong> Allapalli<br />

<strong>and</strong> influence <strong>of</strong> Assamese flora can be seen along entire North South length (e.g. Cephalostachyum pergracile, Lasia<br />

spinosa, Bambusa tulda). Influence <strong>of</strong> Eastern <strong>and</strong> Western Ghats can be seen in the form <strong>of</strong> species such as<br />

Macaranga peltata, Eriolaena hookeriana, Syzygium heyneanum, Schefflera venulosa, Homonoia retusa, Bridelia<br />

retusa, <strong>and</strong> Curcuma pseudomontana among others. Some <strong>of</strong> the relatively rare species <strong>of</strong> Bastar <strong>and</strong> East Gadchiroli<br />

area include Naravelia zeylanica, Canseja rheedii, Osbeckia muralis, Canscora heteroclita, Hygrophila balsamica,<br />

Rhenacanthus nasutus, <strong>and</strong> Amorphophallus sylvaticus. The predominant forest types in the region are Tropical Dry<br />

Deciduous <strong>and</strong> Tropical Moist Deciduous forests with scattered Tropical Semi-evergreen <strong>and</strong> Dry Evergreen forests.<br />

<strong>Special</strong> <strong>Habitats</strong><br />

The region exhibits a great deal <strong>of</strong> habitat heterogeneity in the form <strong>of</strong> highl<strong>and</strong>s, valleys, moist slopes <strong>and</strong> riverine<br />

areas which run along North-South direction <strong>and</strong> connecting Maikal range with Chattisgarh highl<strong>and</strong>s. The Indravati<br />

<strong>and</strong> Wainganga sub-basins have contributed a lot in plant dissemination <strong>and</strong> influenced the flora <strong>of</strong> the region. There<br />

are several hundred hill streams connected through rivulets to the Indravati river, which itself crosses Bailadilla hill<br />

ranges some hundred kilometers eastwards. Thus, Indravati must have played a major role bringing Eastern Ghats<br />

elements as well as Orissa- Mahanadi Basin elements through Bailadilla towards Abujhmar – Bastar highl<strong>and</strong>s <strong>and</strong><br />

Lower Godavari basin. Some <strong>of</strong> the habitats have been discussed here.<br />

i. Salekasa-Darekasa-South Balaghat- Dongargarh Forests<br />

The tracts in Gondia district <strong>of</strong> Maharashtra adjacent to Dongargad hills (West Kawardha) <strong>and</strong> South Balaghat form a<br />

kind <strong>of</strong> moist <strong>and</strong> swamp forests thereby representing a unique habitat. These forests being moist almost throughout<br />

the year <strong>and</strong> the presence <strong>of</strong> several water bodies <strong>and</strong> marshy areas <strong>and</strong> pools (locally called as ‘doh’) in the lowl<strong>and</strong><br />

areas, represent flora which otherwise is missing from Western part <strong>of</strong> Maharashtra. The Navegaon <strong>and</strong> Nagzira area<br />

<strong>and</strong> other marshy areas support very interesting aquatic <strong>and</strong> semi-aquatic flora as well as fauna. <strong>Plants</strong> like Butomopsis<br />

latifolia, Oryza rufipogon, Lasia spinosa, Cephalostachyum pergracile are noteworthy.<br />

ii. Abujhmar-Bastar hills - Lahiri - Damkondawahi Hill Forests<br />

These forests are a mix <strong>of</strong> moist deciduous, dry evergreen <strong>and</strong> riverine forests. Although they are not as marshy as those<br />

<strong>of</strong> Darekasa-Gondia forests, they have formed a unique habitat with respect to deep valleys <strong>and</strong> riverine moist forests<br />

where water is available throughout the year in deeper hill streams. These streams are very important water source for<br />

all the fauna during pinch period. The moist areas harbour diverse insect <strong>and</strong> reptile species. Butterfly diversity <strong>and</strong><br />

density in the summers is amazing. The summer flora even includes plants like Drosera burmanii, Utricularia sc<strong>and</strong>ens,<br />

Pteridophytes, 10-12 species <strong>of</strong> Ficus a variety <strong>of</strong> grasses <strong>and</strong> sedges, which are altogether missing from the adjoining<br />

lowl<strong>and</strong> flora. Memecylon umbellatum var. umbellatum which otherwise found at a higher altitudes in moist Western<br />

<strong>and</strong> Eastern Ghats, is common at streamside at altitude 250 to 300m, while species like Melastomata malbathricum,


Macaranga peltata which are found even at lower altitudes in Western Ghats are found only above 500m in this region.<br />

Abujhmar hills- Bastar hills is a compact but huge block <strong>of</strong> large number <strong>of</strong> undulated hills, valleys <strong>and</strong> streams<br />

bounded by Indravati on the Southern side, Parlkota on the Northern side <strong>and</strong> Pamulgautam passing through its<br />

middle. These hill ranges extend both in Maharashtra <strong>and</strong> Chhattisgarh <strong>and</strong> through Bastar-Jagdalpur are remotely<br />

linked with Eastern Ghats through Bailadilla hills <strong>and</strong> other discontinuous hill ranges. The plateau or madum occurring<br />

between altitude 650 m to 850 m shows lateritic formation <strong>and</strong> trees are represented by typical stunted dry type<br />

vegetation. The Abujhmar hills habitat spreads over 3000 km 2 area.<br />

iii. Kopela – Kolamarka-Bijapur Ghati <strong>and</strong> Parsewada Forests<br />

These forests extend to the South-eastern Gadchiroli district which continues in the Dantewada area (through Indravati Tiger<br />

Reserve-Sundra- Pharsegarh up to Bijapur Ghati-Alabaka hills) in the east <strong>and</strong> adjoining eastern Adilabad District towards<br />

West. These are basically moist deciduous forests with dry evergreen patches interspersed in them. The dry evergreen<br />

species include Manilkara hex<strong>and</strong>ra, Vitex leucoxylon, Syzygium heyneanum, Diospyros malabarica. The Eastern flat<br />

areas adjoining Indravati river (e. g. Chitweli) provides swampy habitat for endangered wild buffalo. These forests are<br />

unique in the sense that the hills are not so prominent but lowl<strong>and</strong> areas show rich moist dense vegetation including<br />

canebrakes in some patches (Plate 22A). Pure Hardwickia binata <strong>and</strong> Manilkara hex<strong>and</strong>ra patches are interspersed with<br />

other forest types in drier areas.<br />

<strong>Plants</strong> <strong>of</strong> High Conservation Significance<br />

Though this l<strong>and</strong>scape is quite rich in plant species diversity, it exhibits very low degree <strong>of</strong> endemism. This may be due<br />

to contiguity <strong>of</strong> l<strong>and</strong>mass with adjacent phytogeographic regions. Nevertheless a large number <strong>of</strong> species in this tract<br />

are common between Western Ghats, Central Highl<strong>and</strong>s, Chotanagpur <strong>and</strong> North-East <strong>India</strong> which signify the past<br />

climatic conditions <strong>and</strong> corridor for floral migration. Macaranga peltata, Melastomata malabathricum, Memycelon<br />

umbelatum, Glochidion zeylanicum, Ficus semicordata, Entada phaseoloides, Buchnania axillaris, Calamus<br />

pseudotenuis, Euonymus godaverensis, Calophyllum inophyllum, Thysonalena maxima, Caryota urens, Ardisia<br />

solanacea, Cephalostachyum pergracile, Premna gmelinoides, Bauhinia retusa, Hydrocotyle sibthorpiodes, Schefflera<br />

elliptica <strong>and</strong> Butomopsis latifolia among others occur in this region which have otherwise distribution along moist<br />

areas <strong>of</strong> rest <strong>of</strong> the <strong>India</strong> or Western Ghats <strong>of</strong> Maharashtra. One <strong>of</strong> the prominent species in this region, Hardwickia<br />

binata, can be considered a typical (broad endemic) <strong>of</strong> Deccan plateau. Locally, several species <strong>of</strong> lower plants e.g.,<br />

Isoetes <strong>and</strong> other pteridophytes may turn out to be endemic which await detailed taxonomic studies. A few species <strong>of</strong><br />

high conservation significance (Plate 22 B) have been given below:<br />

i. Cephalostachyum pergracile Munro. (Poaceae)<br />

Local Name : Panbamboo, Bansari bans<br />

Vegetation Characteristic <strong>and</strong> <strong>Special</strong> <strong>Habitats</strong> in the<br />

Transition Zone <strong>of</strong> Vidarbha – D<strong>and</strong>akaranya, Deccan Plateau<br />

A beautiful bamboo 10 -25 m tall, having yellow-brown sheath <strong>and</strong> black hair. Culms thin, 5-8cm in diameter. Internode<br />

up to 70 cm, branching divergent from all nodes. This species has been recently reported by the author from hilly tracts<br />

<strong>of</strong> Gadchiroli district (Maharashtra). Earlier, it was known to occur in moist tracts <strong>of</strong> northern AP <strong>and</strong> MP. Its present<br />

distribution in this area gives a complete picture on its pattern <strong>of</strong> dispersal i.e., Assam to northern parts <strong>of</strong> AP through<br />

Chhota Nagpur Rajmahal- Maikal –Abujhmar <strong>and</strong> western Orissa. It is confined to hilly regions above 450m, especially<br />

in cooler valleys <strong>and</strong> moist slopes.<br />

Since the culm is hollow it is used by the local communities for ‘Toddy’ extraction. Its long internodes <strong>and</strong> fine straight<br />

fiber is useful in fine bamboo crafts. It is heavily exploited in the region without any conservation or management inputs.<br />

ii. Bambusa tulda Roxb. (Poaceae)<br />

Local Name : Bhalin bans<br />

158<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Another interesting bamboo, 7-20 m high, culms 5-10 cm in diameter, sometimes with yellow streaks. Till recently this<br />

species was known to occur only in the North Eastern parts <strong>of</strong> Central Highl<strong>and</strong>s . However, it has recently been<br />

recorded from Bhamaragad forests <strong>of</strong> Gadchiroli district, Maharashtra. (Dr. Mukteshkumar, KFRI Pers. Comm.) This<br />

species mainly grows in moist localities above 400m asl <strong>and</strong> invariably along narrow strips <strong>of</strong> hill streams. This species<br />

flowered gregariously during summer <strong>of</strong> 2008. Presently it is found with about 150 km 2 area <strong>of</strong> Surjagad, Gatta,<br />

Bhamaragad-Abujhmar hills.<br />

The species has largely been neglected so far as it was though to be an ordinary bamboo Dendrocalamus strictus. No<br />

proper strategies for its scientific management has been evolved.<br />

iii. Lasia spinosa (L.) Thwaites (Araceae)<br />

An aroid herb. Rootstock stout with horizontal stem <strong>and</strong> spiny petioles. Leaves peltate-entire to saggitate dissected.<br />

Lasia spinosa is a recent addition to the flora <strong>of</strong> this region. Basically this is an eastern element seen in riparian marshy<br />

places <strong>and</strong> spring sites. Its present distribution is discontinuous, however habitat is well defined. It will be quite interesting<br />

to study the probable movement <strong>of</strong> this species from North-East to the South <strong>and</strong> its restricted distribution..<br />

This species is restricted to Gondia (Darekasa) <strong>and</strong> Gadchiroli districts (along Bhamaragad, Surajagad <strong>and</strong> Venkatapur-<br />

Aheri hill streams <strong>and</strong> Abujhmar). At present no specific threats are known except restricted habitats <strong>and</strong> small,<br />

vulnerable populations.<br />

Strobilanthes auriculata Nees (Acanthaceae)<br />

This species also grows in moist streamside areas at higher altitudes <strong>of</strong> Darekasa forests <strong>of</strong> Gondia. It has recently<br />

been rediscovered from Maharashtra from where it was thought to have gone extinct. (Dr. Bhuskute, Principal, Godia<br />

College, Pers. Comm.) Earlier, it was known to occur in moist forests <strong>of</strong> Panchmarhi hills (MP). As it represents semievergreen<br />

moist forests <strong>and</strong> has affinities with the species <strong>of</strong> Western Ghats as well as Himalaya, it has special<br />

conservation significance. As <strong>of</strong> now, no direct use <strong>and</strong> immediate threats are known.<br />

Threats to <strong>Habitats</strong> <strong>and</strong> Conservation Implications<br />

One <strong>of</strong> the major threats in this region is shifting cultivation which is practiced in <strong>and</strong> around Abujhmar hills- Rajn<strong>and</strong>gaon<br />

<strong>and</strong> Bastar Hills by Mainly Maria <strong>and</strong> Bada Maria tribes. Thous<strong>and</strong>s <strong>of</strong> hectares <strong>of</strong> prime moist <strong>and</strong> subtropical- hill forests<br />

are slashed, burned <strong>and</strong> used for cultivation <strong>of</strong> Kosari, the local minor millet (a variety <strong>of</strong> Panicum sumatrens). Earlier 30-<br />

40 years <strong>of</strong> cultivation cycle has now come down to 15 years. Thus pristine moist forests are converted rapidly into<br />

miscellaneous low quality open forest dominated with bamboo. This also leads to soil erosion. The area is prone to<br />

frequent fire, which is largely intentional for NTFP collection, getting better Tendu leaves <strong>and</strong> hunting. Since the terrain is<br />

rugged, one can hardly control forest fires once set. Another serious threat to the habitat <strong>and</strong> threatened species in this tract<br />

is spread <strong>of</strong> alien invasive species such as Lantana camara <strong>and</strong> Eupatorium adenophorum especially in shifting cultivation<br />

area.<br />

The Vidarbha – D<strong>and</strong>akaranya l<strong>and</strong>scape harbours one <strong>of</strong> the ancient forest formations in Deccan plateau that has<br />

undergone several changes over the millennia. Today one can trace back a number <strong>of</strong> relict patches <strong>of</strong> vegetation<br />

representing interesting micro-habitats <strong>and</strong> special assemblages <strong>of</strong> plants. These elements indicate that this l<strong>and</strong>scape<br />

is unlike general Deccan plateau but has great affinity with Eastern highl<strong>and</strong>s. The ecotone between dry <strong>and</strong> moist

deciduous forests, dry evergreen <strong>and</strong> riparian forests formed due to hill streams <strong>and</strong> soil type. Distribution <strong>of</strong> birdlife <strong>and</strong><br />

other animals <strong>and</strong> butterflies distribution also indicate the cohesiveness <strong>of</strong> the two regions. Presence <strong>of</strong> butterfly<br />

species Orange Oak-leaf in such a high density as reported by the author in the hill streams has a significant bearing<br />

on the distribution <strong>of</strong> plants. This species has been reported to occur in eastern Ghats south <strong>of</strong> Godavari, Jharkh<strong>and</strong>,<br />

hilly places like Panchmarhi <strong>and</strong> Bhimashankar. The exceptionally high density <strong>of</strong> this species in this transition zone<br />

underlines the fact that flora <strong>and</strong> fauna have distribution along the moist gradients on entire Deccan.<br />

This region can be treated as a large ‘in situ’ plant conservation laboratory <strong>and</strong> studies on phytogeography <strong>and</strong> floral<br />

migration. It is believed that moist <strong>and</strong> cool forested habitats <strong>of</strong> past have gradually transformed form much <strong>of</strong> the<br />

Deccan plateau but for certain pockets which can be seen even today. Thus, there is an urgent need for studying<br />

conservation status <strong>of</strong> such micro-habitats <strong>and</strong> plants assemblage which would help in underst<strong>and</strong>ing the ecological<br />

history <strong>of</strong> the area <strong>and</strong> predicting the future changes.<br />

2Kanger valley national park, Jagdalpur-494001, Chhattisgarh (<strong>India</strong>)<br />

prasad.amarnath@gmail.com<br />

Kanger Valley National Park (KVNP; 200 km 2 ; 18 0 45'00'' to 18 0 56' 30'' N <strong>and</strong> 81 0 51' 30'' to 82 0 10' 00" E) is located in the<br />

Bastar district <strong>of</strong> Chhattisgarh state. It is approachable from Jagdalpur town, some 25 kms towards south-east on<br />

Jagdalpur-Darbha road (Plate 23). The park, starting from Tirathgarh waterfalls to the Kolab River (Orissa boundary),<br />

is nearly 33.5 km long <strong>and</strong> about 6 km broad. The Kanger River forms the main drainage that begins near the<br />

Tirathgarh <strong>and</strong> runs through the middle <strong>of</strong> the park. The altitude varies from 338 to 781m. The mean annual rainfall is<br />

ca 1516.31mm while the mean temperature varies from 10 to 38 ÚC with relative humidity ranging from 40% to 98%<br />

(Jha & Khanna 2005). So far, 456 species <strong>of</strong> flowering plants have been reported (Dixit & Roy 1992, Jha & Khanna<br />

2005). However, during recent floristic surveys the authors have added more than 60 species to the existing list<br />

including about 30 species <strong>of</strong> orchids.<br />

The KVNP comes under Chhattisgarh-D<strong>and</strong>akaranya (Province 6 C2) <strong>of</strong> Deccan Peninsula (Rodgers & Panwar,<br />

1988). According to Vedic literature D<strong>and</strong>akaranya has mythological importance where Lord Rama spent a considerable<br />

time during exile. D<strong>and</strong>akaranya is derived from the Sanskrit word: D<strong>and</strong>aka (= punishment) aranya (= jungle). According<br />

to Ramayana, it was home <strong>of</strong> many deadly creatures <strong>and</strong> demons. Exiled persons resided here <strong>and</strong> sages had to cross<br />

it in order to reach the Vindhya Mountain Range.<br />

This article gives a brief description <strong>of</strong> vegetation, habitat <strong>and</strong> selected plants <strong>of</strong> high conservation significance.<br />

Vegetation Types<br />

The KVNP has a special ecological significance as it forms a natural transition zone between Sal (Shorea robusta) <strong>and</strong><br />

Teak (Tectona gr<strong>and</strong>is) forests in Peninsular <strong>India</strong>. Though the park is relatively small in size, it supports several distinct<br />

vegetation types in close vicinity <strong>of</strong> each other viz., Tropical Moist Deciduous, Tropical Dry Deciduous <strong>and</strong> Tropical<br />

Semi-Evergreen Forests (Champion & Seth 1968, Jha & Khanna 2005). The special habitats within the park are<br />

riverine forests, rocky outcrops <strong>and</strong> hill tops which harbour a large number <strong>of</strong> interesting species <strong>and</strong> a variety <strong>of</strong><br />

medicinal plants. Broadly the forests <strong>of</strong> this park can be categorized into following types:<br />

i. The Tropical Moist Deciduous (Sal) Forests : This type consists <strong>of</strong> two sub-types (a) Moist Peninsular Hill Sal <strong>and</strong><br />

(b) Moist Peninsular Valley Sal. The former type occurs in undulating slopes <strong>and</strong> hill tops. The common trees <strong>of</strong> this<br />

type include Shorea robusta, Terminalia tomentosa, Dillenia pentagyna, Miliusa tomentosa, Anogeissus latifolia,<br />

Pterocarpus marsupium, Emblica <strong>of</strong>ficinalis, Buchanania lanzan, Diospyros melanoxylon, Ougeinia oojeinensis, Kydia<br />

calycina, Bridelia retusa, Dendrocalamus strictus, Phoenix acaulis, Grewia sp., Woodfordia fruticosa, Bauhinia vahlii,<br />

Smilax zeylanica, <strong>and</strong> Butea superba. The Moist Peninsular Valley Sal is largely found along the valleys. The common<br />

associates <strong>of</strong> Sal in this category are Terminalia tomentosa but Dillenia is not present. Champion & Seth (1968)<br />

reported excellent Sal regeneration in these forests.<br />

Some <strong>of</strong> the special <strong>and</strong> interesting habitats <strong>of</strong> KVNP which harbour rich flora <strong>and</strong> interesting species are described,<br />

in brief, below:<br />

(a). Undulating <strong>and</strong> Rocky Slopes : The terrain <strong>of</strong> KVNP is almost hilly with deep gorges <strong>of</strong> Kanger river. Hill tops <strong>and</strong><br />

slopes have poor <strong>and</strong> skeletal soil derived from lateritic <strong>and</strong> ferruginous conglomerates. This type <strong>of</strong> habitat is dominated<br />

by Shorea robusta in association with Dillenia sp., Anogeissus latifolia, Terminalia tomentosa, Pterocarpus marsupium,<br />

Syzygium sp., Schleichera oleosa, Haldina cordifolia, Mallotus philippensis, Garuga pinnata, Xylia xylocarpa,<br />

Zanthoxylum rhetsa <strong>and</strong> Hedyotis auricularia. A few species <strong>of</strong> high conservation significance in these areas include<br />

Zingiber roseum, Curcuma amada, Costus speciosus, Curculigo orchioides, Asparagus racemosus, <strong>and</strong> Chlorophytum<br />

arundinaceum. Besides, a few terrestrial orchids (e.g., Geodorum densiflorum, Habenaria spp., <strong>and</strong> Peristylus<br />

plantagineus), some epiphytic orchids viz., Rhynchostylis retusa, Aerides sp., Dendrobium sp., Cymbidium aloifolium<br />

<strong>and</strong> Pelatantheria insectifera can be seen in this habitat. Dendrophthoe falcata, Viscum angulatum, <strong>and</strong> V. orientale are<br />

common parasites.<br />

(b). Dry Plateaus : Some parts <strong>of</strong> Tirathgarh, Kotamsar, Darbha <strong>and</strong> Koleng area represent dry plateau which have<br />

mixed Sal <strong>and</strong> Teak forests. Other characteristic species on the plateau Chloroxylon swietenia, Boswellia serrata,<br />

Sterculia urens, Alstonia venenata, Lannea corom<strong>and</strong>elica, Anogeissus latifolia, Gardenia turgida, G. latifolia, Madhuca<br />

longifolia, Butea monosperma <strong>and</strong> Ziziphus oenoplia. Around Darbha <strong>and</strong> Koleng, Sal grows in association with<br />

Cleistanthus collinus, Erythrina suberosa, Ochna obtusata, Garuga pinnata, Sterculia urens, Anogeissus latifolia,<br />

Lannea corom<strong>and</strong>elica, Bombax ceiba, Cochlospermum religiosum, Dendrobium peguanum <strong>and</strong> Dendrocalamus<br />

strictus. The Kotamsar <strong>and</strong> Tirathgarh plateaus have open teak forests with common associates such as Pterocarpus<br />

marsupium, Sterculia urens, Schleichera oleosa, Lannea corom<strong>and</strong>elica, Anogeissus latifolia, Diospyros melanoxylon<br />

<strong>and</strong> Dillenia species.<br />

(c). Riverine <strong>Habitats</strong> : Kanger River <strong>and</strong> some perennials streams represent riverine habitats which are characterized<br />

by the presence <strong>of</strong> Salix tetrasperma, Trema orientalis, Terminalia arjuna, Diospyros malabarica, Mitragyna parvifolia,<br />

Pongamia pinnata, Syzygium spp, Ficus racemosa <strong>and</strong> Memecylon umbellatum. Typical herbaceous species <strong>of</strong> riverine<br />

area include Centella asiatica, Caesulia axillaries, Ludwigia hyssopifolia, Ludwigia perennis, Ficus lanceolata, Lippia<br />

javanica, Polygonum sp., Carex cruciata, Cyperus sp., Fimbristylis sp., Kyllinga sp. <strong>and</strong> Vetiveria zizanioides. In addition,<br />

several seasonal herbs appear in such areas subsequent to rains. Ottelia alismoides, Vallisneria natus, Hydrilla<br />

verticillata are common submerged aquatic herbs. Open moist areas harbour a few insectivorus plants such as<br />

Drosera burmannii, Utricularia aurea <strong>and</strong> U. bifida, associated with lower plants viz., Pteridium sp., Pteris sp., Equisetum<br />

sp., Marsilea sp. <strong>and</strong> Riccia fluitans.<br />

(d). Bamboo brake : Bhainsadarha area is dense with bamboo forest including four different species viz.<br />

Dendrocalamus strictus, Oxytenanthera nigrociliata, Cephalostachyum pergracile <strong>and</strong> Bambusa arundinacea. Foothills<br />

<strong>and</strong> shady moist ravines are mostly covered by Cephalostachyum pergracile.

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

<strong>Threatened</strong> <strong>Plants</strong>: Roy & Chaturvedi (1987) <strong>and</strong> Kumar & Sikarwar (2002) studied the rare <strong>and</strong> endangered plants <strong>of</strong><br />

Bastar region <strong>and</strong> reported that over exploitation, invasive species <strong>and</strong> encroachment are the major threats to native<br />

plants <strong>and</strong> their habitat. Drosera burmannii, Eulophia sp., Dendrobium peguanum, Rauvolfia serpentina, Gymnema<br />

sylvestre, Strychnos nux-vomica, Vitex leucoxylon, Gloriosa superba, Caryota urens, Riccia fluitans <strong>and</strong> Costus speciosus<br />

have declined in the area over the years <strong>and</strong> hence, need to be prioritized for long term conservation. Some <strong>of</strong> these<br />

species are briefly described below:<br />

1. Drosera burmannii Vahl. (Droseraceae)<br />

Local Name: Mohinibooty<br />

Insectivorous herb. Leaves in basal rosettes, appressed to ground, green with purple center, margin gl<strong>and</strong>ular-hairy. Fl.<br />

& Fr.: Sep.-Jan. growing along the bank <strong>of</strong> Kundru-Jodi nallah (Plate 23).<br />

2. Caryota urens Linn. (Arecaceae)<br />

Local Name: Salphi<br />

A tall palm. Spadices 3-4m long, Flowers unisexual. Fl. & Fr.: October-March. Stem sap is tapped for making alcohol<br />

(Sulphi). At places it is planted by the local people because it serves as cash crop. However, it is highly threatened in<br />

other areas due to over exploitation. Within KVNP only 2-3 individuals can be seen especially in Pulcha beat.<br />

3. Dendrobium peguanum Lindl. (Orchidaceae)<br />

Epiphytic orchid. Pseudobulbs globose with membranous sheaths. Leaves linear-oblong. Inflorescence terminal on<br />

leafless stem. Flowers fragrant, 1–1.5cm across, white, lip pale brown, veined with dark brown to purple, anterior lobe<br />

purple. Fruits globose. Fl. & Fr.: December–March. <strong>Threatened</strong> species for Central <strong>India</strong>. A few individuals can be seen<br />

in Koleng beat.<br />

4. Rauvolfia serpentina (L.) Benth. ex Kurz. (Apocynaceae)<br />

Local Name: Kukut-ch<strong>and</strong>i<br />

Erect under-shrubs. Leaves in whorls <strong>of</strong> 3-7. The flowers are drupaceous, white, pinkish or red. Heavily exploited<br />

throughout <strong>India</strong> for its medicinal properties. Rare in KVNP. Fl. & Fr.:Oct.-Dec.<br />

24.0 Chotanagpur Plateau: Relict <strong>Habitats</strong> <strong>and</strong> Endemic<br />

<strong>Plants</strong><br />

Introduction<br />

1Pankaj Kumar & G.S. Rawat<br />

Department <strong>of</strong> Habitat Ecology, Wildlife Institute <strong>of</strong> <strong>India</strong>, Ch<strong>and</strong>rabani,<br />

Dehradun – 248001, Uttarakh<strong>and</strong>, <strong>India</strong><br />

1pankajsahani@rediffmail.com Chotanagpur plateau is one <strong>of</strong> the oldest l<strong>and</strong>masses on earth. It is composed <strong>of</strong> Precambrian rocks which are more<br />

than 540 million years old. It is a collective name for the Ranchi, Hazaribagh, <strong>and</strong> Koderma plateaus, having an area<br />

<strong>of</strong> ca 65,509 km 2 . Of these, Ranchi is the largest. The plateau in its entirety lies between the basins <strong>of</strong> the Ganges <strong>and</strong><br />

Son rivers to the north <strong>and</strong> the Mahanadi River to the south. Through its centre, from west to east, runs the coal-bearing,<br />

faulted Damodar Valley. Numerous streams have dissected the upl<strong>and</strong>s into a peneplain (an area reduced almost to a<br />

plain by erosion) with isolated hills. To the north <strong>of</strong> Chotanagpur lies the Rajmahal Hills which are very important on<br />

account <strong>of</strong> their fossiliferous deposits. Some <strong>of</strong> the important fossils found in the area are Sahnioxylon rajmahalense,<br />

Pentoxylon sahnii, Sahania nipaniensis, Nipaniophyllum hobsoni, Carnoconites compactus <strong>and</strong> Nipanioxylon guptaii.<br />

Biogeographically, Chotanagpur plateau has a special significance. It forms the northern limit <strong>of</strong> Peninsular <strong>India</strong> that<br />

lies within Paleotropic region. Rodgers <strong>and</strong> Panwar (1988), in their Biogeographic Classification <strong>of</strong> <strong>India</strong>, recognized<br />

this plateau as part <strong>of</strong> province 6B (Deccan peninsula). The plateau has drawn the attention <strong>of</strong> several phytogeographers.<br />

Nayar (1996) identified 20 centres <strong>of</strong> plant endemism in <strong>India</strong>, <strong>of</strong> which Chotanagpur is one that has been recognized<br />

as an important ‘microcentre’.<br />

In this article we give an overview <strong>of</strong> the plant wealth, patterns <strong>of</strong> plant endemism <strong>and</strong> localities <strong>of</strong> botanical interest on<br />

the Chotanagpur plateau <strong>and</strong> suggest a few measures for their conservation.<br />

Biophysical Features<br />

The forest vegetation <strong>of</strong> the Chotanagpur Plateau is represented by three major groups as per the classification by<br />

Champion & Seth (1968): (i) Tropical Moist Dedicuous Forests (3C/C3a <strong>and</strong> 3C/E1), (ii) Northern Tropical Dry Deciduous<br />

Forests (5B/C1c, 5B/C2 <strong>and</strong> 5/DS2) <strong>and</strong> (iii) Central <strong>India</strong>n Subtropical Hill Forests (8A/C3). The total vegetation cover<br />

on the plateau is about 29.61 %. Out <strong>of</strong> this, 3.19% area is under very dense forest cover whereas 11.39% has<br />

moderately dense forests, 13.76% has open forests <strong>and</strong> 0.92% area has scrubl<strong>and</strong>. There are 3 National Parks <strong>and</strong> 20<br />

Wildlife Sanctuaries (Singh et al. 2001). According to Wildlife database there is 1 existing National Park <strong>and</strong> 2 proposed,<br />

whereas 11 Wildlife Sanctuaries existing <strong>and</strong> 2 are proposed (http://www.wii.gov.in/nwdc/index.html).<br />

The climate <strong>of</strong> the plateau is Tropical monsoon type with three distinct seasons, viz., summer (March to mid June),<br />

Monsoon (mid June to October) <strong>and</strong> winter (November to February). May is the hottest month with temperature going<br />

up to 45ÚC. During May <strong>and</strong> June the state also experiences hot winds knows as loo. January is the coldest month with<br />

temperature ranging from 6ÚC to 22ÚC. The average rainfall varies between 100 cm to 150 cm. Likewise, the humidity<br />

varies from 38% (April - May) to 94% (August – September). On the basis <strong>of</strong> the ratio <strong>of</strong> total monthly precipitation <strong>and</strong><br />

total monthly evaporation, Thronthwaite (1933) has placed the state under dry sub-humid category. The plateau has<br />

predominantly red soil that is derived from peculiar rock formations. This soil exhibits high percentage <strong>of</strong> acid soluble<br />

Ferric oxide <strong>and</strong> lower pH ranging from 5 – 6.8. In some higher parts <strong>of</strong> the plateau laterite soil is also found.<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Chotanagpur has a human population <strong>of</strong> around 26.91 million <strong>of</strong> which 22.50% are <strong>of</strong> tribal origin, belonging to more<br />

than 30 different tribes. They are mostly dependent on the forest resources for their living. Some <strong>of</strong> these tribes are,<br />

Baiga, Santal, Asur, Chero, Gond, Larmali, Kond, Kurmi, Tharu, Munda, etc. Recent findings have suggested that the<br />

pre-Dravidian aborigines, whose descendants are speakers <strong>of</strong> the Munda Austric languages, living today in parts <strong>of</strong><br />

Chotanagpur (Jharkh<strong>and</strong>), Chhattisgarh, Orissa, Bengal, <strong>and</strong> so on are the original inhabitants <strong>of</strong> <strong>India</strong>. This fact<br />

makes the area anthropologically unique.<br />

(http://en.wikepedia.org/wiki/Dravidian_people).<br />

Floral Wealth <strong>and</strong> Endemism<br />

Despite a large number <strong>of</strong> floral surveys, there is no comprehensive account on the angiosperm flora <strong>of</strong> Chotanagpur<br />

Plateau. However the flora <strong>of</strong> erstwhile Bihar (that includes the state <strong>of</strong> Jharkh<strong>and</strong> which encompasses maximum part<br />

<strong>of</strong> the Chotanagpur Plateau), has recorded 186 families, <strong>of</strong> which 148 are dicotyledons <strong>and</strong> 38 are monocotyledons.<br />

Total number <strong>of</strong> species in erstwhile Bihar is 2963 which belongs to 1151 genera (Singh et al. 2001). The plateau has<br />

played an important role in the migration <strong>of</strong> plants from Eastern Himalayas, Assam, Myanmar, Malaya <strong>and</strong> other<br />

countries <strong>of</strong> the South-East. <strong>Plants</strong> have migrated from here to Western <strong>and</strong> Eastern Ghats <strong>and</strong> Sri Lanka. It is also<br />

believed that in the geological past, this plateau formed a link between Satpura Hill Ranges <strong>and</strong> eastern Himalaya that<br />

allowed species exchanges between these ranges (Hora 1949). Jharkh<strong>and</strong> is even recognised as a distinct geographic<br />

region (IND-JK) in <strong>India</strong>n subcontinent by Kew (Brummitt 2001).<br />

The plateau has altogether 14 endemic taxa (Some endemic to <strong>India</strong> <strong>and</strong> others endemic to Jharkh<strong>and</strong>). The following<br />

table gives the details <strong>of</strong> these taxa:<br />

Some Unique <strong>Habitats</strong> <strong>and</strong> Associated Flora<br />

i. Parasnath Hills : Parasnath Hills are situated towards the centre <strong>of</strong> the state <strong>of</strong> Jharkh<strong>and</strong> in the Giridih District. Apart<br />

<strong>of</strong> it (49.3 km2) was designated as a Wildlife Sanctuary in 1984. The highest elevation goes to approximately 1500m<br />

asl. Clarke (1898) <strong>and</strong> Haines (1921 – 24) have suggested that the hills <strong>of</strong> Parasnath may have served in the past as<br />

stepping stone for the passage <strong>of</strong> plant species between the hills <strong>of</strong> Peninsular <strong>India</strong> <strong>and</strong> Eastern Himalaya. With<br />

respect to vegetation this area is unique due to the presence <strong>of</strong> Montane subtropical forests (8A/C3) above 1220 m asl


on this hills (Champion & Seth 1968). Some <strong>of</strong> the commonly found species in this area above 1220m are, Pittosporum<br />

wightii, Grewia spp., Meyna spinosa, Berberis asiatica, Reinwarditia indica, Thallictrum foliolosum, Polygala spp.,<br />

Lobelia alsinoides,, L. heyneana, Clematis gouriana, etc. The areas between 650 – 1220 are dominated by Litsea<br />

monopetala, Ficus microcarpa, F. mollia, Symplocos racemosa, Alangium salvifolium, Indig<strong>of</strong>era pulchella, Vitis spp.,<br />

Bauhinia vahlii, B. sericea var. anguina, Persea bombycina, Chionanthus ramiflorus <strong>and</strong> Caesalpinia bonduc to name<br />

a few (Plates 24A, 24B & 24C).<br />

ii. Sar<strong>and</strong>a Forests : Sar<strong>and</strong>a is a dense forest in the hilly region <strong>of</strong> West Singhbhum district. Sar<strong>and</strong>a literally means<br />

seven hundred hills. It is supposed to be one <strong>of</strong> the largest sal forests in Asia. The forest covers an area <strong>of</strong> 820 km².<br />

Amongst these forests lies a scenic village, called Thalkobad, at a height <strong>of</strong> 550 m (1,800 ft) in the heart <strong>of</strong> the forest.<br />

This area represents a very nice habitat for Orchids including all the 11 species <strong>of</strong> Dendrobiums <strong>and</strong> it is a home for the<br />

last remnant population <strong>of</strong> Bulbophyllum, an epiphytic orchid represented by single species, Bulbophyllum crassipes.<br />

Another interesting orchid <strong>of</strong> this region is Pecteilis triflora, which is found only at two places in <strong>India</strong>, one being<br />

Sar<strong>and</strong>a forests <strong>and</strong> the other site is in the western Himalaya in Tons Valley, Uttarkh<strong>and</strong>. Sar<strong>and</strong>a also hides amongst<br />

its dense forests, Ligirdah swamp which harbours unique swamp vegetation dominated by the members <strong>of</strong> family<br />

Zingiberaceae such as Hedychium coronarium <strong>and</strong> other families <strong>of</strong> sedges <strong>and</strong> grasses. The swamp is deep enough<br />

to engulf huge wild Elephants <strong>and</strong> is surrounded by dense sal forests. The reserved forests are the home for many<br />

animals like, wild elephants (common), sambar, chital, bison, leopards <strong>and</strong> even tigers, though they were never<br />

numerous but they are there.<br />

iii. Netarhat : This is a densely forested area dominated by both moist <strong>and</strong> dry deciduous sal forests. The elevation<br />

ranges from 600m – 950m asl, with minor <strong>and</strong> major streams. One <strong>of</strong> the highest waterfalls called the Lodh Falls is<br />

located in these forests along with the famous Mahuadanr Wolf Sanctuary. Lodh Falls represents an ideal riverine<br />

ecosystem, harbouring a very important economic orchid <strong>of</strong> this region, called Pholidota imbricata, locally called<br />

“Pathal Kela”, literally meaning, ‘banana growing on high cliff rocks’. The forests are ideal habitat for orchid species,<br />

especially Dendrobiums (Plate 24C). Ten out <strong>of</strong> 11 species <strong>of</strong> Dendrobiums are found in this locality. Economically this<br />

area is highly suited for the cultivation <strong>of</strong> Pyrus cummunis (Family: Rosaceae), commonly called as Naspati.<br />

iv. Barkapahar, Ranchi – Khunti Highway : This is a small hillock <strong>of</strong> aproximately 130m high ranging from 650m -<br />

780m above sea level <strong>and</strong> it is called Barka Pahar by the locals <strong>of</strong> the area, which is basically in comparison to another<br />

small barren hillock nearby. On the steep slopes there are Sal forests at some places <strong>and</strong> at some places there are<br />

mixed forests with Acacia spp. <strong>and</strong> Bauhinia variegata. On the gentle slopes towards the foothills are Shorea robusta,<br />

Bauhinia, Nyctanthes arbor-tristis. There are some Terminalia alata trees too scattered all over the hillock. In the mixed<br />

forests Shorea robusta is dominant species alongwith many species <strong>of</strong> undershrubs. A river runs along half the stretch<br />

<strong>of</strong> its foothills.<br />

This hillock practically remained untouched by the scientific community <strong>and</strong> uninhabited by the local tribal community.<br />

Local tribal communities, use the l<strong>and</strong> at the foot <strong>of</strong> the hillock for agriculture. The hillock recently gained importance<br />

due to the presence <strong>of</strong> 24 species <strong>of</strong> orchids <strong>of</strong> which 19 were collected specifically from the hillock <strong>and</strong> rest were from<br />

the trees scattered distantly on the plains below the hillock. Out <strong>of</strong> these 19 species, 16 are terrestrial, 2 are epiphytic<br />

<strong>and</strong> 1 is saprophytic. These represent around 40% <strong>of</strong> the total Orchids found in the whole state <strong>of</strong> Jharkh<strong>and</strong>.<br />

Conservation Issues <strong>and</strong> Strategies<br />

Chotanagpur Plateau:<br />

Relict <strong>Habitats</strong> <strong>and</strong> Endemic <strong>Plants</strong><br />

Despite all its marvelous biogeographical significance <strong>and</strong> uniqueness, Chotanagpur Plateau is not even prioritized for<br />

conservation by the <strong>India</strong>n government, most probably because nowadays, conservation is based on effortlessness,<br />

rather than the necessity!<br />

According to Joshi <strong>and</strong> Dash (2006), the biodiversity <strong>of</strong> Jharkh<strong>and</strong> is under severe threat due to human induced<br />

activities, industries, mining, settlement, development projects <strong>and</strong> removal <strong>of</strong> forest products, overgrazing <strong>and</strong> forest<br />

fires. Majority <strong>of</strong> forest is lost due to industrialization <strong>and</strong> extraction <strong>of</strong> minerals from the earth crust. There is an urgent<br />

need to conserve the rich biodiversity <strong>of</strong> the state before the treasure is lost. There is an immediate need for the in situ<br />

conservation <strong>of</strong> this special habitat, i.e., Chotanagpur Plateau on whole as well as its biodiversity. Being one <strong>of</strong> the<br />

oldest l<strong>and</strong>masses on earth, the Chotanagpur Plateau might be hiding some unforeseen information concerning the<br />

evolution <strong>of</strong> earth as well as its biodiversity.<br />

The state <strong>of</strong> Orissa (1,55,707 km 2 ; 17 0 49' N to 22 0 34' N <strong>and</strong> 81 0 27' to 87 0 29' E) is situated on the eastern coast <strong>of</strong> <strong>India</strong>.<br />

It is bestowed with varied physiographic conditions, moderately high rain fall (142.2-157.5 cm. per annum) <strong>and</strong> relative<br />

humidity (61.5-78.0%), <strong>and</strong> a fine network <strong>of</strong> perennial river systems providing congenial conditions for a rich flora. The<br />

state has about 37% forest cover which is much higher than the national average (Anonymous 2006) <strong>and</strong> it is credited<br />

with five <strong>of</strong> the sixteen major forest types <strong>and</strong> 32 sub-types occurring in <strong>India</strong> (Champion & Seth 1968). The five main<br />

categories <strong>of</strong> forests within the state are (i) Orissa Semi-evergreen forests (ii) Tropical moist deciduous forests (iii)<br />

Tropical dry-deciduous forests (iv) Central <strong>India</strong>n hill forests <strong>and</strong> (v) Littoral <strong>and</strong> Tidal swamp forests (Panigrahi 1983).<br />

Biogeographically, the state falls in three zones viz., Deccan Peninsula (Chotanagpur <strong>and</strong> Eastern Highl<strong>and</strong>s), Lower<br />

Gangetic Plain (7B) <strong>and</strong> East Coast (8B) as per classification by Rodgers et al., (2002). Meher-Homji (2001) has<br />

recognized three phytogeographic regions in the state, i.e., Deccan Plateau, Eastern Ghats <strong>and</strong> the Coastal Plains.<br />

The state is underlain largely by the Precambrian rocks. The geological formations reflect a complex <strong>of</strong> igneous<br />

metamorphic <strong>and</strong> sedimentary rocks with alluvial <strong>and</strong> coastal alluvial plains, each giving rise to distinct soil type which<br />

range from alluvial (coastal <strong>and</strong> riverine types) to lateritic <strong>and</strong> Black cotton.<br />

Till date about 3,000 species <strong>of</strong> angiosperms <strong>and</strong> Pteridophytes have been recorded from the state (Panigrahi 1990).<br />

The flora <strong>of</strong> the state is mainly known through the monumental work <strong>of</strong> H.H. Haines (1921-25). His treatise “The Botany<br />

<strong>of</strong> Bihar <strong>and</strong> Orissa”, supplemented by H.F. Mooney (1950) serves as a much-needed baseline for all further floristic<br />

studies in the state. The contribution by Gamble & Fischer (1915-36) who provided accounts <strong>of</strong> northern forest circle<br />

<strong>of</strong> the Madras Presidency (southern part <strong>of</strong> modern Orissa) also remains invaluable. Similarly, the work <strong>of</strong> Panigrahi et<br />

al. (1964), Rao & Banerjee (1967) <strong>and</strong> Saxena & Brahmam (1994-96) <strong>and</strong> the district flora scheme <strong>of</strong> Botanical Survey<br />

<strong>of</strong> <strong>India</strong> covering different districts <strong>of</strong> the state have made significant contributions in recent times. In addition, exhaustive<br />

work by S. Mishra <strong>and</strong> A.K. Dubey need special mention who have contributed immensely on Orchidaceae <strong>and</strong><br />

Poaceae <strong>of</strong> Orissa respectively. Biswal & Choudhury (1994) have documented flora <strong>of</strong> different protected areas in the<br />

state. However, no comprehensive assessment <strong>of</strong> the rare, threatened <strong>and</strong> endangered species have been carried out,<br />

except for report <strong>of</strong> the CAMP (Conservation Assessment <strong>of</strong> Medicinal <strong>Plants</strong>) Workshop organized under the aegis <strong>of</strong><br />

Orissa Forest Department <strong>and</strong> Foundation for Revitalisation <strong>of</strong> Local Health Traditions, Bangalore which has listed 41<br />

species (Ved et.al. 2008). Other exercises which aim at prioritization have been woefully short <strong>of</strong> their desired aim – for<br />

instance, in a recently concluded meeting <strong>of</strong> experts for state-wide identification <strong>of</strong> critically endangered species, just<br />

a single species was identified for Orissa. This was despite the fact that the habitat <strong>and</strong> species richness <strong>of</strong> the state is<br />

very rich <strong>and</strong> represents about 20 percent <strong>of</strong> the total flora <strong>of</strong> <strong>India</strong> (Panigrahi 1990) with 2727 species (1062 genera,<br />

228 families <strong>of</strong> angiosperms with 28 endemic species) reported from the entire state (Saxena & Brahmam 1983).<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

In this paper we present a synoptic overview <strong>of</strong> the state <strong>and</strong> its floristic regions with special emphasis on botanical<br />

hotspots, along with a tentative list <strong>of</strong> the rare, endangered <strong>and</strong> threatened (RET) species with brief descriptions <strong>of</strong><br />

selected threatened taxa. A few localities <strong>of</strong> high botanical interest have been mentioned which have remained underexplored<br />

<strong>and</strong> need studies. This exercise has largely been undertaken by consulting existing information derived from<br />

published works mentioned above, supplemented by primary data collected by the first author from various parts <strong>of</strong> the<br />

state during the last two decades <strong>and</strong> intensive field work done by both authors in Mayurbhanj district from 2006 to<br />

2008. The IUCN Red list categories (Mace & Stuart 1994) have been followed for the criteria used for the present<br />

assessment, which includes factors such as population reduction, extent <strong>of</strong> occurrence, area <strong>of</strong> occupancy, population<br />

size <strong>and</strong> the probability <strong>of</strong> extinction in wild. We realize that in many cases, there is data deficiency on the exact<br />

population status <strong>of</strong> different taxa due to paucity <strong>of</strong> studies. Further, there might also be differences in opinion regarding<br />

the relative abundances, degree <strong>of</strong> threats <strong>and</strong> potential for long-term survival in different areas <strong>of</strong> the state. Nevertheless,<br />

an attempt is made to generate a baseline which can be supplemented/modified in future with availability <strong>of</strong> more<br />

concrete data from field.<br />

Prioritising taxa for conservation : the approach<br />

The plant specimens from Orissa housed in various herbaria viz., Central National Herbarium Calcutta (CAL), Forest<br />

Research Institute, Dehradun, Institute <strong>of</strong> Minerals <strong>and</strong> Materials Technology, Regional Plant Resource Centre, P.G.<br />

Department <strong>of</strong> Botany, Utkal University (all three in Bhubaneswar) <strong>and</strong> that <strong>of</strong> P.G. Department <strong>of</strong> Botany, North Orissa<br />

University, Baripada were critically examined. The work <strong>of</strong> some notable workers (Haines (l.c.), Mooney (l.c.), Gamble<br />

& Fischer (1925-1936), Jain & Rao (1983), Jain & Sastry (1983), Nayar & Sastry (1987), Saxena & Brahmam (1994-96),<br />

Anonymous (2007a) <strong>and</strong> Ved et al. (2008) also served as major sources <strong>of</strong> information. In addition, field observations<br />

made in the forests <strong>of</strong> Orissa since 1989 in connection with different projects provided supplementary information for<br />

assessing the status. The CAMP workshop report (Ved et. al. 2008) was also referred.<br />

Phytogeographical Divisions <strong>and</strong> Characteristic Floral Elements<br />

Orissa has four distinct geographical <strong>and</strong> ecological divisions:<br />

Coastal plains having 40,191 sq. km (18% <strong>of</strong> the state) <strong>and</strong> a forest cover <strong>of</strong> 7958 sq. km, includes 11 districts <strong>and</strong> the<br />

brackish water Chilika lake <strong>and</strong> Bhitarkanika mangrove forests. Apart from a host <strong>of</strong> mangrove <strong>and</strong> mangrove associates,<br />

species <strong>of</strong> special conservation significance which occur in this region include Rhizophora stylosa, Sonneratia griffithii,<br />

Avicennia marina var. acutissima, K<strong>and</strong>elia c<strong>and</strong>el, Indig<strong>of</strong>era, aspalathoides, Synostmon bassiforme, Stylosanthes<br />

fruticosa, Cassipourea ceylanica, Salicornia brachiata, Phoenix paludosa, etc.<br />

The Northern Plateau with 28,433 sq. km. in area, includes four districts with a forest cover <strong>of</strong> 11,046 sq.km covering<br />

the Similipal Biosphere <strong>and</strong> large hill ranges with a general slope from North to South. The important hill ranges are<br />

Malayagiri (1,188 m), Mankarnacha (1,177 m) <strong>and</strong> the Meghasani (1,116 m). The major rivers namely Brahmani,<br />

Baitarani <strong>and</strong> Budhabalanga <strong>and</strong> numerous rivulets have their origin from this plateau. Among the the threatened<br />

species confined to this region are Eria meghasanienesis, Hypericum gaitiii, Aspidopterys tomentosa var. hutchinsonii,<br />

Zeuxine affinis, Peristylus parishii, Acanthephippium bicolor, Acanthephippium sylhetens, Phoebe lanceolata, Clematis<br />

roylei, Baccaurea ramiflora, etc.<br />

Central table l<strong>and</strong>s having 36,536 sq. km in area <strong>and</strong> which includes seven districts with a forest cover <strong>of</strong> 10,536 sq.<br />

km. The three prominent rivers Mahanadi, Brahamani <strong>and</strong> Baitarani flow parallel to each other making this region<br />

agriculturally fertile <strong>and</strong> thickly populated. Eusteralis griffithii, Homonoia intermedia, Uvaria eucincta, Aglaia haslettiana,<br />

Psoralia corylifolia, Desmos longiflorus, etc. are among the interesting taxa <strong>of</strong> conservation importance.


Eastern Ghats having 49,827 sq. km with 17041 sq. km <strong>of</strong> mountainous region <strong>and</strong> forests, spread in eight districts.<br />

The prominent mountain peaks <strong>of</strong> the state namely Mahendragiri (1,500 mt), Singharaju (1,515 mt), Turiakonda<br />

(1,599 mt) <strong>and</strong> Deomali (1,673 mt) are located in this tract. The area is noted for the presence <strong>of</strong> Dimeria<br />

mahendragiriensis, Oryza jeyporensis, Selaginella nairii, Themeda mooneyi, Wendl<strong>and</strong>ia gamblei, Pecteilis henryi<br />

<strong>and</strong> Strobilanthes jeyporensis.<br />

Results <strong>and</strong> Discussion<br />

After analysis, 117 taxa belonging to Angiospermic, Gymnospermic <strong>and</strong> Pteridophytic flora have been prioritized for<br />

conservation in Orissa (Table-1). Of these, 19 have been enlisted as threatened taxa based on IUCN criteria. While 7<br />

taxa were found to be near-threatened, 28 were vulnerable, 22 were data deficient <strong>and</strong> 21 were not evaluated. Of the<br />

62 families represented, Orchidaceae was the dominant family with 8 taxa followed by Fabaceae with 7; Meliaceae,<br />

Clusiaceae, Euphorbiaceae <strong>and</strong> Mimosaceae with 4 each; Annonaceae, Bignonceae, Caesalpiniaceae, Liliaceae<br />

<strong>and</strong> Lauraceae with 3 each; Acanthaceae, Apiaceae, Apocynaceae, Loganiaceae, Myrtaceae, Salvadoraceae <strong>and</strong><br />

Sterculiaceae with 2 each while the rest had a single species. In terms <strong>of</strong> growth form these species represent 47 trees,<br />

20 shrubs, 19 climbers, 27 herbs <strong>and</strong> 3 ferns.<br />

Floral hotspots <strong>and</strong> suggested areas for future exploration<br />

Orissa enjoys the unique privilege <strong>of</strong> being the meeting ground <strong>of</strong> the flora <strong>of</strong> the northern tropical forests <strong>and</strong> the largely<br />

endemic flora <strong>of</strong> the southern <strong>India</strong>. As a whole, it exhibits wide-ranging affinity with the flora <strong>of</strong> other phytogeographic


egions <strong>of</strong> the country, viz. Eastern Himalayas, Gangetic Plains <strong>and</strong> the Western Ghats. Though the state has a vast<br />

forest area, there are certain l<strong>and</strong>scapes/areas which harbours a series <strong>of</strong> unique <strong>and</strong> special habitats with exceptional<br />

floristic richness. The notable among them are the extensive hills <strong>of</strong> Similipal in Mayurbhanj along with its staellite<br />

areas <strong>of</strong> Kuldiha <strong>and</strong> Hadgarh, Gonasika-Kanjipani-Telkoi tract in Keonjhar, Karlapat in Kalah<strong>and</strong>i, Sunabeda plateau<br />

in Nawapara, Kotgarh in Phulbani <strong>and</strong> the high E.Ghat hills <strong>of</strong> Deomali, Mahendragiri, Niyamagiri <strong>and</strong> Kondakameru<br />

in southern Orissa. Others worth mentioning are Badarama <strong>and</strong> Khalasuni forests in Western Orissa, <strong>and</strong> the gorge <strong>of</strong><br />

Mahanadi at Satkosia. Not to be forgotten are the river deltas <strong>of</strong> Mahanadi, Brahmani <strong>and</strong> Baitarani which support a<br />

luxuriant mangrove flora, especially at Bhitarkanika. The vast brackish water lagoon <strong>of</strong> Chilika is also home to an<br />

unparalleled aquatic <strong>and</strong> semi-aquatic floral diversity. Many <strong>of</strong> these remain poorly explored <strong>and</strong> await detailed studies<br />

which are sure to reveal hitherto unknown species. Predominant among the largely unexplored areas are the remote<br />

gorges <strong>and</strong> evergreen forests <strong>of</strong> southern Similipal, especially in the core area <strong>of</strong> the Tiger Reserve; the extensive<br />

forests <strong>of</strong> Daringbadi-Bhanjnagar complex <strong>of</strong> Phulbani district, Rebna <strong>and</strong> Ranjagarh hills; Palaspal <strong>and</strong> forests<br />

around Meghanada Parbat; secluded hills east <strong>of</strong> Banaigarh; the high hills <strong>of</strong> Kalah<strong>and</strong>i including Karlapat with peaks<br />

beyond 5000 ft; highl<strong>and</strong>s <strong>of</strong> Koraput, interiors <strong>of</strong> Sunabeda plateau <strong>and</strong> high l<strong>and</strong>s <strong>of</strong> Khariar. Among other relatively<br />

less-explored areas are the hilly tracts near Jeypore <strong>and</strong> Koraput bordering Andhra Pradesh, hills near Russelkonda<br />

<strong>and</strong> Subarnagiri, the spurs east <strong>of</strong> Rairakhol, <strong>and</strong> the hilly tracts north-west <strong>of</strong> Sambalpur. Also <strong>of</strong> high botanical interest<br />

are the farther isl<strong>and</strong>s <strong>of</strong> Chilika lake <strong>and</strong> some remote tidal creeks <strong>and</strong> swamps along the deltas <strong>of</strong> Mahanadi <strong>and</strong><br />

Dhamra rivers (Plates 25A & 25B).<br />

Threats <strong>and</strong> Conservation efforts<br />

<strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> Orissa <strong>and</strong> Priority<br />

Species for Conservation<br />

Among the myriad threats to floral wealth, loss <strong>of</strong> habitat <strong>and</strong> fragmentation at an alarming rate must certainly rank as<br />

the first. Though anthropogenic habitat alteration by way <strong>of</strong> cropl<strong>and</strong> conversion, shifting cultivation, etc. has existed<br />

since eons, there has been unprecedented acceleration recently by way <strong>of</strong> increasing mining activity, especially in the<br />

hilly mineral-rich tracts <strong>of</strong> hinterl<strong>and</strong> Orissa. Many <strong>of</strong> the hotspots mentioned elsewhere in this paper are under the<br />

imminent threat <strong>of</strong> being destroyed gradually. Increasing encroachments <strong>and</strong> subsequent urbanization is also a serious<br />

threat to erstwhile pristine areas. Aquatic ecosystems including a number <strong>of</strong> wetl<strong>and</strong>s get altered irreparably by<br />

aquaculture <strong>and</strong> l<strong>and</strong> reclamation. In addition to these are the chronic problems <strong>of</strong> forest fire, especially in the dry<br />

deciduous forests <strong>of</strong> western <strong>and</strong> southern Orissa <strong>and</strong> gradual spread <strong>of</strong> invasive species in almost all the forest types.<br />

A more serious <strong>and</strong> recent cause for concern is also the emergent market for herbal products, which has resulted in<br />

unscrupulous <strong>and</strong> unsustainable collection <strong>of</strong> medicinal plants, many local populations <strong>of</strong> which have either been<br />

wiped out or are at the verge <strong>of</strong> local extinction. Species which were extremely common till the recent past like<br />

Rauvolfia serpentina, Rubia cordifolia <strong>and</strong> Gloriosa superba are all nearing extermination in the state. The state tree<br />

<strong>of</strong> Orissa, Saraca asoca is also no exception!<br />

However, a slew <strong>of</strong> in situ <strong>and</strong> ex situ conservation measures is being adopted by both by government agencies as well<br />

as organizations in the non-governmental sector. As many as eighteen wild life sanctuaries <strong>and</strong> two national parks have<br />

been established in order to safeguard the wildlife in general <strong>and</strong> threatened species in particular. In addition, 5 in situ<br />

Medicinal Plant Conservation Areas (MPCAs) have been established at Satkosia (Mayurbhanj), Patalganga (Nuapada),<br />

Pradhanpat (Deogarh), Kapilas (Angul) <strong>and</strong> Berbera (Khurda). Ex situ collections as in the various Botanical Gardens,<br />

most notably that in N<strong>and</strong>an Kanan <strong>and</strong> Regional Plant Research Centre, Bhubaneswar are also valuable steps in the<br />

right direction. The recent initiative by the Forest Department to identify, map <strong>and</strong> conserve all forest blocks with Saraca<br />

asoca <strong>and</strong> mass-propagate <strong>and</strong> plant seedlings is also a commendable initiative aimed at species-specific conservation.<br />

More such measures are needed if we are to conserve the entire spectrum <strong>of</strong> floral diversity <strong>of</strong> the state for posterity. The<br />

first step, however, has to be a comprehensive field-based assessment <strong>of</strong> threatened flora be carried out in a phased,<br />

state-wide <strong>and</strong> systematic manner in the light <strong>of</strong> existing information so that existing hotspots can be prioritized for<br />

effective conservation <strong>and</strong> fresh ones identified for future action.<br />

26.0 Floristic wealth <strong>of</strong> Javvadhu Hills, Eastern Ghats,<br />

With <strong>Special</strong> Emphasis on <strong>Threatened</strong> <strong>Plants</strong><br />

Javvadhu hills, an important extension <strong>of</strong> Eastern Ghats, are spread across Vellore, Tiruvannamalai <strong>and</strong> Krishnagiri<br />

districts <strong>of</strong> Tamil Nadu. This hill range stretches over 80 kms in length <strong>and</strong> 32 kms in width. Oriented in northeast –<br />

southwest direction, this range lies in the northern part <strong>of</strong> the Tamil Nadu between 12º 15' to 12º 40' N latitudes <strong>and</strong> 78º<br />

2' to 79º 10' E longitudes. The hills rise steeply from the plains forming an undulating plateau on the top to the altitude<br />

<strong>of</strong> about 800 m <strong>and</strong> enclose small valleys. Melpattu, on the Thenmalai hills with an altitude <strong>of</strong> 1045 m is the highest<br />

peak in the range. The average height <strong>of</strong> the Javvadhu hills is c 500 m. Malayalis - the hill dwelling tribes inhabit in the<br />

hill range (Ravikumar & Vijaya Sankar 2003).<br />

Vegetation <strong>and</strong> Habitat Characteristics<br />

Javvadhu hills are known for their rich vegetation. They also harbour a number <strong>of</strong> wild plant resources such as edible<br />

fruits, tubers <strong>and</strong> vegetables <strong>and</strong> other non-timber forest produces including medicinal plants. The forest types found<br />

in this hill range, as per the classification by Champion & Seth (1968) are: Southern Dry Mixed Deciduous Forests,<br />

Southern Dry Deciduous Scrub Forests, Southern Dry Savannah Forests, Dry Bamboo Brakes, Dry Tropical Riverain<br />

Forests, Southern Tropical Thorn Forests <strong>and</strong> Southern Thorn Scrub Forests. The hill range is home for<br />

several endemics <strong>and</strong> threatened plants. About 800 taxa <strong>of</strong> plants are reported to be present in the entire range <strong>of</strong><br />

Javvadhu hills.<br />

Geologically the Javvadhu hills represent ancient rock formations which are largely ferruginous in composition <strong>and</strong><br />

chiefly containing hornblende <strong>and</strong> feldspar. This has given rise to peculiar reddish loam <strong>of</strong> varying depth <strong>and</strong> fertility. On<br />

the plateaus the soil is usually loamy or gravelly <strong>of</strong>ten greyish brown in colour due to admixture <strong>of</strong> humus. In valleys the<br />

soil is clayey <strong>and</strong> cankarous. The high iron content is always apparent in most <strong>of</strong> the reserved forests in disturbed areas,<br />

where the surface soil has been completely eroded leaving only the hardened subsoil devoid <strong>of</strong> any fertility owing to<br />

excessive grazing in these parts. There is a deficiency <strong>of</strong> lime in the soils where s<strong>and</strong>alwood trees are present.<br />

The climate <strong>of</strong> the hill range is tropical <strong>and</strong> moderately hot <strong>and</strong> dry. Forest areas in higher altitudes are cooler than the<br />

lower areas. The year can be divided into three seasons viz. summer during March-May, rainy during June-October<br />

<strong>and</strong> winter from November to February. It is very hot during April to June. The average maximum temperature in shade<br />

is 32º C <strong>and</strong> the average minimum is 19ºC. Frost does not occur here except for a few occasional dewfalls. The hill<br />

range receives maximum rainfall from the southwest as well as northeast monsoons. The average annual rainfall in<br />

the district is 1,075 mm.<br />

The Red Listed <strong>Plants</strong><br />

The following Red Listed species assessed during rapid assessment workshops conducted by the FRLHT in different<br />

states <strong>of</strong> <strong>India</strong> (Ravikumar & Ved 2000) have been collected from Javvadhu hills:<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Though several taxa <strong>of</strong> plants in the hill range are facing a high risk <strong>of</strong> threat owing to a variety <strong>of</strong> factors, the following<br />

are worth mentioning <strong>and</strong> need immediate conservation action.<br />

1. Brachystelma brevitubulatum (Bedd.) Gamble (Asclepiadaceae)<br />

Slender twiners. Leaves linear-lanceolate, 8-11 × 0.4-0.8 cm, base cuneate, with a brown gl<strong>and</strong>, apex acuminate.<br />

Cymes umbellate, 3(4)-flowered. Flowers c 3.5 cm long, c 1.5 cm across; corolla-tube short, connate at base <strong>and</strong><br />

apex, up to 3 mm long; petals 5, ovate-lanceolate, 2-3.5 × 0.5-0.8 cm, purple-brown within, greenish yellow without.<br />

Follicles c 7.5 × 0.4 cm, tapering towards apex. Seeds c 10, oblong, compressed, c 5 × 2 mm, brown; coma silky-white,<br />

unequal, up to 3 cm long (Plate 26B).<br />

This species is Endemic to Javvadhu hills in Eastern Ghats <strong>of</strong> Tamil Nadu. It is rarely found along exposed grassy<br />

slopes in Paruvathamalai <strong>and</strong> Swamimalai R.F. Fl.: Oct.-Nov.; Fr.: Nov.-Apr.<br />

Note: This potentially ornamental plant was first collected by Beddome in 1871 from Amerdy (Amirthi) forest <strong>of</strong> Javvadhu<br />

hills near Vellore. During floristic study <strong>of</strong> Tiruvannamalai district it was rediscovered after a lapse <strong>of</strong> 131 years <strong>and</strong> also<br />

from other than the type locality. So far only eleven individuals have been noticed (8 from Paruvathamalai <strong>and</strong> 3 from<br />

Swamimalai R.F.) as a result <strong>of</strong> thorough perambulation in the above localities. There is every possibility for its<br />

occurrence in similar habitats (i.e. grassy, rocky slopes in woodl<strong>and</strong> savannahs) in adjescent districts too. Planned <strong>and</strong><br />

focused explorations may help to ascertain the actual population size <strong>and</strong> distribution <strong>of</strong> this narrow endemic species.<br />

This species is <strong>of</strong> prime conservation concern due to its taxonomical <strong>and</strong> distributional importance. The present<br />

locations are facing threats <strong>of</strong> forest fire <strong>and</strong> grazing in addition to the growing human interference in the form <strong>of</strong><br />

pilgrims. An appropriate in situ conservation action is urgently needed to preserve this precious species before it<br />

disappears from its prestine locality. Moss multiplication through seeds <strong>and</strong> tissue culture technique <strong>and</strong> reintroduction<br />

in the suitable habitats are also suggested (Vijaya Sankar et al., 2003).<br />

2. Panicum fischeri Bor (Poaceae)<br />

Tufted herbs, up to 1 m high. Leaves linear, c 30 × 1 cm, base narrowed, apex acuminate. Panicles diffuse, up to 45 ×<br />

30 cm. Spikelets: one short-pedicelled (3 mm long), another with long pedicel (11 mm long); lower glume 2 mm long,<br />

lobed, acuminate, 3-nerved, midnerve prominent; upper glume 4.2 × 2 mm, 7-nerved, acuminate, lead-grey. Lower<br />

floret male or barren; lower lemma 4 mm long, lead-grey, 9-nerved, nerves prominent on the upper half, lower half <strong>of</strong><br />

lemma transparent; palea scareous, keeled, folded, up to 3 mm long. Upper floret bisexual, with an appendage (which<br />

2.5 mm long), transparent, stiff, acuminate, lanceolate; lemma 3 mm long, smooth, boat-shaped, obtuse; upper palea<br />

3 mm long, smooth, scarious, shiny; stamens 3, pink, 2 mm, divergent; stigma plumose (that starts from 1 mm), 2.5 mm<br />

long, dark purple; lodicules 2.<br />

This species is Endemic to Tamil Nadu. It grows among other grasses such as Apluda mutica, Cymbopogon spp. in the<br />

slopes <strong>of</strong> Savannah forests in Paruvathamalai above 500 m altitude. Fl. & Fr.: Oct.-Dec. RVS 71245, 102223.<br />

Note: Gamble first collected this unique grass from Kullar (Kallar) in the Nilgiris, Western Ghats, in 1886. The present<br />

collection from Paruvathamalai, Javvadhu hills, after a lapse <strong>of</strong> about 120 years from its type collection, shows its<br />

extended distribution in the Eastern Ghats. In the present locality this species also is facing threats <strong>of</strong> grazing, forest fire<br />

<strong>and</strong> soil erotion in addition to human interference in the form <strong>of</strong> pilgrims. Suitable conservation measures have to be<br />

taken up in order to protect this endemic species before it vanishes from this habitat. Grazing should be completely<br />

banned <strong>and</strong> collection <strong>of</strong> thatch grass should be regulated. Strict vigilance on forest fire <strong>and</strong> establishing horizontal<br />

raised bunds along slopes may prevent this species from extinction.(Vijaya Sankar 2006).


3. Barleria pilosa Wall. ex Nees (Acanthaceae)<br />

Tamil : Sunnaambu chedi<br />

Undershrubs, up to 1 m high; young parts pilose; mature branchlets terete, young ones obscurely 4-gonous. Leaves<br />

ovate-elliptic, 2-4 × 1-2.5 cm, subcoriaceous, densely lineolate <strong>and</strong> pilose along nerves above, base attenuate, apex<br />

acute to very shortly acuminate, margin ciliate; lateral nerves 4-pairs, converging towards apex; petioles up to 5 mm<br />

long. Flowers solitary, axillary, shortly pedicellate; bracts ovate-elliptic, c 5 × 4 mm, pilose; calyx-lobes 4, outer ones<br />

broadly ovate, c 2 × 1.5 cm, 5-7-nerved, reticulate, long-pilose, base obtuse, apex acute, margin sharply denticulateciliate;<br />

inner lobes 2, linear-oblong, c 7 × 1.5 mm, pilose; corolla c 3 cm across, 5-lobed, puberulous without; tube c 2<br />

This species is endemic to Tamil Nadu. It is rarely found along streams in Karnatigur R.F., Javvadhu hills. Fl. & Fr.:<br />

Dec.-Feb. RVS 102201.<br />

Note: This species has so far been reported only from the W.Ghats <strong>of</strong> Coimbatore (Anamalai hills) <strong>and</strong> Tirunelveli<br />

(Courtallam) districts. The present collection <strong>of</strong> this endemic species from Javvadhu hills forms new report to the<br />

E.Ghats as well as extends the known distribution towards north <strong>of</strong> the State. Only few old collections by Rottler, Wight<br />

(Courtallam), Beddome <strong>and</strong> Fischer (Coimbatore) are available at MH, BSI, Coimbatore.<br />

Loss <strong>of</strong> forest cover in the tropics has always been associated with burgeoning human population <strong>and</strong> rapid changes<br />

in l<strong>and</strong> use (Rudel & Roper 1997, Lamb et al. 2005). Extensive deforestation leads to formation <strong>of</strong> forested isl<strong>and</strong>s<br />

within larger l<strong>and</strong>scapes (Cayuela et al. 2006). Forests not only form the most important renewable natural resource on<br />

earth but also render numerous ecosystem services to mankind which cannot be equated in monetary terms as some<br />

<strong>of</strong> the economists try to do these days. In developing countries like <strong>India</strong>, dependence <strong>of</strong> people on forests is inevitable<br />

<strong>and</strong> in most <strong>of</strong> the economically impoverished areas pressure on forests is mounting at alarming rate (Jayakumar et al.<br />

2002). The poorer forest dwellers regard logging <strong>and</strong> forest clearing as the only way to earn their livelihood <strong>and</strong> hardly<br />

respond to conservation appeals in the absence <strong>of</strong> any better alternative (Barbier 1993). As a result, most <strong>of</strong> the <strong>of</strong>ficial<br />

conservation programmes fail (Rudel 2006). Depletion <strong>of</strong> forest has many ecological, social <strong>and</strong> economic<br />

consequences, one among them being the loss <strong>of</strong> biodiversity (Jayakumar et al. 2002, Wills et al. 2006).<br />

The Eastern Ghats <strong>of</strong> <strong>India</strong> harbour diverse tropical forests, which have undergone drastic degradation <strong>and</strong><br />

fragmentation. Contemporary history <strong>of</strong> forest fragmentation <strong>and</strong> its ecological consequences in this tract have not<br />

been documented. At the same time there are quite a few natural pockets <strong>of</strong> evergreen forests which have evolved<br />

under peculiar micro-habitats <strong>and</strong> geomorphological conditions. Such forests are limited in extent <strong>and</strong> resemble the<br />

‘shola’ forests <strong>of</strong> Western Ghats <strong>and</strong> can be considered as special habitats. Very little ecological studies have been<br />

conducted on these forests. In this article we give a brief description <strong>of</strong> these forests <strong>and</strong> report the occurrence <strong>of</strong> a few<br />

characteristic plant species which need conservation action.<br />

Shola (Evergreen) Forests <strong>of</strong> south Eastern Ghats as <strong>Special</strong> <strong>Habitats</strong><br />

The Eastern Ghats <strong>of</strong> <strong>India</strong> is a broken chain <strong>of</strong> hills that runs almost parallel to east coast <strong>of</strong> <strong>India</strong> covering three states<br />

viz., Orissa, Andhra Pradesh <strong>and</strong> Tamil Nadu. The southern portion <strong>of</strong> Eastern Ghats comprises a few major hills<br />

namely, Sathyamangalam, Melagiris, Javadi, Shervarayan, Chitteri, Kalrayan, Bodamalai, Pachamalai <strong>and</strong> Kolli hills.<br />

Shervarayan hills with maximum altitude <strong>of</strong> 1649 m above mean sea level is the most elevated hill in southern Eastern<br />

Ghats. In terms <strong>of</strong> geographical area, Sathyamangalam (1719 km 2 ) is the largest hill range in the Eastern Ghats. These<br />

ranges harbour five major forest types, viz. tropical evergreen, semi-evergreen, mixed-deciduous, dry deciduous <strong>and</strong><br />

thorn forests. Evergreen forests are distributed only at the hill tops. Semi-evergreen forests are distributed at high<br />

altitude, <strong>and</strong> mixed- <strong>and</strong> dry deciduous forests are distributed on the slopes with middle altitude. While the thorn forests<br />

are typically found in the foot hills. Some times they also occur at middle elevation, as a result <strong>of</strong> degradation <strong>of</strong> dry<br />

deciduous forests. In southern Eastern Ghats, evergreen forests are considered as special habitat as their distribution<br />

is restricted to small patches in a few high altitude hill tops <strong>of</strong> Sathyamamgalam, Shervarayan, Chitteri, Kalrayan,<br />

Pachamalai <strong>and</strong> Kolli hills. Of particular mention include sites such as Alathi shola <strong>of</strong> Kalrayan hills, Kannimar shola <strong>of</strong><br />

Pachamalai <strong>and</strong> Ariyur <strong>and</strong> Kuzhivalavu sholas <strong>of</strong> Kolli hills are patches <strong>of</strong> dense evergreen forests as good <strong>and</strong> dense<br />

as <strong>of</strong> wet evergreen forests <strong>of</strong> Western Ghats. Threats to these patches include l<strong>and</strong> use change for hill agriculture <strong>and</strong><br />

various plantation crops including fruit crop particularly pine apple in Kolli hills, tapioca cultivation in Alathi shola.<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

The evergreen sholas <strong>of</strong> southern-most Eastern Ghats are peculiar in various ways. They are located usually at hill tops<br />

between 750 to 1649m asl. They share many species with shoals <strong>of</strong> Western Ghats. They have moderately high plant<br />

species diversity with dominant evergreen elements <strong>and</strong> multi-layered canopy structure. The epiphytic orchids, ferns<br />

<strong>and</strong> mosses are common. Interestingly, they have high frequency <strong>of</strong> occurrence <strong>of</strong> latex / resinous rich woody plants.<br />

The trees are usually tall <strong>and</strong> voluminous, loaded with epiphytes <strong>and</strong> leaves with epiphylls. Climax forest canopy tree<br />

species can reach up to 30-40 m in height. Trees are rarely multi-stemmed <strong>and</strong> lianas are usually abundant <strong>and</strong> thick<br />

stemmed. The forest floor is usually laden with thick layer <strong>of</strong> litter that harbors dense arthropod population. Site photos<br />

<strong>and</strong> some important plants <strong>of</strong> southern-most Eastern Ghats are shown in Plate 27.<br />

Geologically these hill ranges comprise masses <strong>of</strong> charnokite associated with gneisses <strong>and</strong> varied metamorphic<br />

rocks. Sathyamangalam has two large reservoirs, Bavanisagar dam on the south-west <strong>and</strong> Mettur dam on the northeast<br />

direction. Cauvery is the major river that passes through Sathyamangalam forests. Vellar, Ponnaiyar <strong>and</strong> Kollidam<br />

are the three rivers which originate from southern Eastern Ghats. These rivers are the major water source for the<br />

farmers in central Tamil Nadu. Among all the areas S Sathyamangalam hills have special biogeographic significance<br />

as several floral <strong>and</strong> faunal elements find their dispersal path through this range between Western <strong>and</strong> Eastern Ghats.<br />

Among large mammals, the Asian elephant <strong>and</strong> tiger are reported from this area. The other animals <strong>of</strong> Sathyamangalam<br />

include common leopard, sambar, wild dog, <strong>India</strong>n bison or gaur, wild pig <strong>and</strong> golden jackal.<br />

Tribal settlements are common in all hills. The tribal people <strong>of</strong> southern Eastern Ghats are called ‘Malayalees’. The<br />

hilly terrain <strong>and</strong> the surrounding plains <strong>of</strong> southern Eastern Ghats are densely populated. The ever-increasing human<br />

population <strong>and</strong> settlements in forested areas, <strong>and</strong> construction <strong>of</strong> roads <strong>and</strong> dams, lead to degradation <strong>of</strong> forest<br />

l<strong>and</strong>scape <strong>and</strong> ultimately forest habitats are threatened at an alarming rate.<br />

The mangroves are unique ecosystems found in the tropical <strong>and</strong> sub-tropical inter-tidal regions <strong>of</strong> the world. They are<br />

among the most productive habitats dominated by salt tolerant vegetation, popularly known as ‘Tidal Swamp Forests’,<br />

‘Littoral Swamp Forests’, or Oceanic Rain Forests’. The word ‘mangrove’ is interchangeably used for salt tolerant<br />

plants as well as forest ecosystem. Hence, Macnae (1968) proposed the terms ‘Mangal’ to denote this special ecosystem<br />

<strong>and</strong> ‘Mangroves’ for the plants adapted to grow in such habitats. The mangrove plants are specialized to tolerate high<br />

salinity, tidal extremes, high fluctuations in wind, temperature <strong>and</strong> muddy anaerobic soil. No other groups <strong>of</strong> terrestrial<br />

plants survive well under such conditions. A muddy substratum <strong>of</strong> varying depth <strong>and</strong> consistency is necessary for their<br />

growth. The plants have special adaptations such as stilt roots, viviparous germination, salt-excreting leaves, breathing<br />

roots, <strong>and</strong> knee roots by which these plants survive in water-logged, anaerobic saline soils <strong>of</strong> coastal environments.<br />

Also, the mangrove plants have great potential to adapt to the changes in climate, rise in sea levels <strong>and</strong> to the incidence<br />

<strong>of</strong> solar ultraviolet–B radiation (Rahaman 1990, Swaminathan 1991, Moorthy 1995, Moorthy & Kathiresan 1996).<br />

<strong>India</strong> harbours some <strong>of</strong> the best mangrove forests <strong>of</strong> the world which are located in the alluvial deltas <strong>of</strong> major rivers<br />

such as the Ganga, Mahanadi, Godavari, Krishna, Cauvery <strong>and</strong> also on the bay <strong>of</strong> Andaman <strong>and</strong> Nicobar Isl<strong>and</strong>s.<br />

According to the Forest Survey <strong>of</strong> <strong>India</strong> (Anonymous 2003) total area under mangrove forests in the country is 4,461 km 2<br />

which forms 0.14% <strong>of</strong> the country’s geographical area <strong>and</strong> is 5% <strong>of</strong> the world’s mangrove vegetation. About 58.32% <strong>of</strong><br />

<strong>India</strong>’s mangrove forests are located along the east coast <strong>and</strong> 24.61% on the west coast. The Bay Isl<strong>and</strong>s (Andaman<br />

& Nicobar) account for 15.04% <strong>of</strong> the country’s mangroves. Mangroves are much more extensive on the east coast <strong>of</strong><br />

<strong>India</strong> due to nutrient-rich alluvial soil formed by the several rivers which also supply fresh water along the deltaic coast.<br />

The west coast mangroves are dominated by estuarine back waters, which include the coastal areas <strong>of</strong> Gujarat,<br />

Maharashtra, Goa, Karnataka <strong>and</strong> Kerala. The east coast has a smooth <strong>and</strong> gradual slope which provides larger areas<br />

for colonization <strong>of</strong> mangroves whereas the west coast has a steep <strong>and</strong> vertical slope. Mangroves in Andaman <strong>and</strong><br />

Nicobar Isl<strong>and</strong>s are oceanic in nature, fringing the creeks, back waters <strong>and</strong> muddy shores.<br />

Mangroves <strong>of</strong> Orissa<br />

Mangrove forests along coast <strong>of</strong> <strong>India</strong> cover approximately an area <strong>of</strong> 207 km 2 . These forests are distributed in the<br />

deltas <strong>of</strong> six rivers viz., Subernarekha, Budhabalanga, Baitarani, Brahmani, Mahanadi <strong>and</strong> Devi. While mangroves <strong>of</strong><br />

Subarnarekha, Budhabalanga <strong>and</strong> Devi river deltas have been degraded, they are still intact in Bhitarkanika (Baritarani<br />

<strong>and</strong> Brahmani deltaic complex). In fact, Bhitarkanika mangroves (130 km 2 ) contribute substantially to the state’s<br />

mangrove vegetation <strong>and</strong> form second largest mangrove ecosystem in the <strong>India</strong>n sub-continent after Sunderbans.<br />

Mangroves <strong>of</strong> Mahanadi delta to the south <strong>of</strong> Bhitarkanika are open <strong>and</strong> in a state <strong>of</strong> degradation due to intensive<br />

human interference such as developmental projects <strong>and</strong> industries. Mangroves were also reported to occur in the<br />

fringes <strong>of</strong> Chilika lake till the turns <strong>of</strong> previous century which have been disappeared now. Besides protection <strong>of</strong> the<br />

coastal environment from the fury <strong>of</strong> cyclone, mangroves provide multiple economic benefits to the coastal communities.<br />

There are about 25 mangrove species along the west coast (Banerjee et al. 1989). The east coast <strong>of</strong> <strong>India</strong> <strong>and</strong><br />

Andaman-Nicobar Isl<strong>and</strong>s exhibit a higher degree <strong>of</strong> species diversity as well as a unique distribution <strong>of</strong> mangrove<br />

elements. The important mangrove families represented in <strong>India</strong> are Avicenniaceae, Combretaceae, Arecaceae<br />

(Palmae), Rhizophoraceae <strong>and</strong> Sonneratiaceae (Banerjee et al. 1989). Review <strong>of</strong> literature revealed that about 42 true<br />

mangroves <strong>and</strong> 40 mangrove associates are extant in the Bhitarkanika mangrove forest in Orissa. A comparative<br />

account <strong>of</strong> mangrove <strong>and</strong> mangrove associates occurring in Mahanadi delta <strong>and</strong> Bhitarkanika <strong>of</strong> Orissa <strong>and</strong> other<br />

states along the east coast including Andaman <strong>and</strong> Nicober Isl<strong>and</strong>s have been provided in Table-2. Mangrove<br />

ecosystem <strong>of</strong> Bhitarkanika exhibits maximum species diversity in the country (Rao et al. 1970, Banerjee & Das 1972,<br />

Rao & Sastry 1974, Banerjee 1984 & 1986, Banerjee & Rao 1990). Cerbera manghas, Sonneratia caseolaris, Heritiera<br />

kanikensis, Amoora cuculata, Acanthus volubilis, Merope angulata, Xylocarpus mekongensis, Ceriops tagal <strong>and</strong><br />

Sonneratia alba are some <strong>of</strong> the rare <strong>and</strong> threatened mangrove species in Orissa coast (Plate 28).<br />

Status <strong>and</strong> Distribution<br />

Orissa has comparatively larger mangrove habitats in the country due to nutrient rich alluvial soils formed by the river<br />

Mahanadi delta <strong>and</strong> the Brahamani-Baitarani delta. The coast also has a smooth <strong>and</strong> gradual slope which provides<br />

larger areas for colonization <strong>of</strong> mangroves. As per an estimate the state has a total mangrove areas <strong>of</strong> 207 km 2<br />

distributed over four coastal districts (Table-1) that include 160 km 2 (77%) moderately dense mangroves <strong>and</strong> 47 km 2<br />

(23 %) open mangroves cover in 2003 (State <strong>of</strong> Forest Report 2003). Mangroves <strong>of</strong> Bhitarkanika (Brahmani-Baitarani<br />

river deltas) are quite extensive <strong>and</strong> abundant as compared to those present in the Mahanadi delta. The mangroves <strong>of</strong><br />

Devi river mouth, Budhabalanga <strong>and</strong> Subarnarekha river mouths are in highly degraded state.<br />

River Mouths <strong>of</strong> Subernarekha <strong>and</strong> Budhabalanga : Mangroves <strong>of</strong> river mouths <strong>of</strong> Subernarekha <strong>and</strong> Budhabalanga<br />

covering an area <strong>of</strong> 563ha, at present are in highly degraded state owing to heavy biotic pressure. Vegetation is<br />

represented by shrubby elements <strong>and</strong> stunted forms <strong>of</strong> tree species. The notable mangrove species are Avicennia<br />

<strong>of</strong>ficinalis, Bruguiera gymnorrhiza, Sonneratia apetala, Excoecaria agallocha, Rhizophora mucronata, Bruguiera<br />

cylindrica, Ceriops dec<strong>and</strong>ra, Acanthus ilicifolius, Caesalpinia nuga, Myriostachya wightiana, Suaeda maritima,<br />

Porteresia coarctata, etc. About 50 ha <strong>of</strong> degraded l<strong>and</strong>s have been planted with seedlings <strong>of</strong> Avecennia spp., Excoecaria<br />

agallocha, Ceriops dec<strong>and</strong>ra, Rhizophora mucronata, Bruguira gymnorrhiza, Aegiceras corniculatum, etc. by the Orissa<br />

Forest Department during 2001-2002 (Reddy 2002).<br />

Bhitarkanika : Bhitarkanika (672 km 2 ) harbours luxuriant <strong>and</strong> wide-spread mangrove vegetation (130 km 2 ). This area<br />

has a total <strong>of</strong> 42 true mangroves, 40 mangrove associates <strong>and</strong> 9 obligate mangroves. It provides ideal habitat to<br />

estuarine crocodile <strong>and</strong> several other faunal communities (P<strong>and</strong>av 1996, Daniels <strong>and</strong> Acharjyo 1997). The mangrove

species occurring in Bhitarkanika exhibits two storey systems (Choudhury 1990). The ground flora is either poor or<br />

absent, top canopy is dominated by mangrove species viz., Sonneratia apetala, Avicennia <strong>of</strong>ficinalis, A. alba, Excoecaria<br />

agallocha, Heritiera fomes, Pongamia pinnata, while the second storey is composed <strong>of</strong> shrubby <strong>and</strong> under tree species<br />

such as Brownlowia tersa, K<strong>and</strong>elia c<strong>and</strong>el, Lumnitzera racemosa, Rhizophora mucronata, Ceriops dec<strong>and</strong>ra, Cynometra<br />

iripa, Clerodendrum inerme, Aegiceras corniculatum, Hibiscus tiliaceus, etc. Gregarious <strong>and</strong> luxuriant growth <strong>of</strong> Avicennia<br />

spp. <strong>and</strong> Sonneratia apetala are found along banks <strong>of</strong> river <strong>and</strong> creeks in Bhitarkanika. While Pongamia pinnata <strong>and</strong><br />

Xylocarpus granatum occupy habitats close to the water bodies, in more elevated areas mixed forests <strong>of</strong> Heritiera<br />

fomes <strong>and</strong> Excoecaria agallocha are met with. While Phoenix paludosa, Tamarix indica, Hibiscus tiliaceus, Heritiera<br />

littoralis are found in pure formations, Bruguiera gymnorrhiza, Cerbera manghas, Ceriops dec<strong>and</strong>ra, etc. are found in<br />

low frequency. The ground level, close to river banks <strong>and</strong> estuaries is muddy <strong>and</strong> studded with pneumatophores.<br />

Except a few patches <strong>of</strong> grasses herbaceous elements are devoided. However, a little distance from the river banks,<br />

Acanthus ilicifolius, Acrostichum aureum, Flagellaria indica, etc. in the moist areas <strong>and</strong> Salicornia brackiata, Suaeda<br />

nudiflora, Tylophora indica, etc. are in the dry region are usually found as herbaceous elements. The common associates<br />

as the category <strong>of</strong> climbers/thinners are Derris trifoliata, Mucuna gigantean, Acanthus volubilis, Caesalpinia nuga,<br />

Dalbergia spinosa, etc. Some mangrove species like Cerbera manghas, Acanthus volubilies <strong>and</strong> Heritiera kanikensis<br />

are found only in Bhitarkanika. Of these, the later two species are endemic to Orissa. Occurrence <strong>of</strong> 3 species each <strong>of</strong><br />

Avicennia, Heritiera, Sonneratia, Rhizophora <strong>and</strong> Xylocarpus <strong>and</strong> 4 species <strong>of</strong> Bruguira are significant for Bhitarkanika<br />

forests (Mukherjee <strong>and</strong> Mukharjee 1978).<br />

Mahanadi Delta : The dominant mangrove species occurring in Mahanadi delta are Avicennia <strong>of</strong>ficinalis, A. marina,<br />

A. alba, Excoecaria agallocha, Rhizophora mucronata, <strong>and</strong> Sonneratia apetala, etc. The mangroves in the region are<br />

degrading rapidly due to habitat alteration for agricultural system, development <strong>of</strong> prawn firms <strong>and</strong> <strong>of</strong> port facilities at<br />

Paradeep. These developmental activities moved many taxa towards threatened categories i.e., Merope angulata,<br />

Tamarix dioica, Bruguira sexangula, Sonneratia caseolaris, Sonneratia alba, Sonneratia griffithii, Sarcolobus carinatus,<br />

S. globosus, Xylocarpus mekongensis <strong>and</strong> Dolich<strong>and</strong>rone spathacea. There are 34 true mangroves, 42 mangrove<br />

associates <strong>and</strong> 20 obligate mangroves are present in Mahanadi delta.<br />

Devi River Mouth : Devi river arises from river Kathjodi, a tributary <strong>of</strong> river Mahanadi drains into Bay <strong>of</strong> Bengal forming<br />

a tidal estuary with me<strong>and</strong>ering creeks <strong>and</strong> channels. The estuary <strong>of</strong> Devi river is almost devoid <strong>of</strong> typical mangrove<br />

elements mainly due to habitat destruction connected with human settlement <strong>and</strong> paddy cultivation in the areas.<br />

Moreover, the ecological conditions have been changed due to formation <strong>of</strong> s<strong>and</strong> bars which considerably checked<br />

inundation. Only patches <strong>of</strong> Acanthus ilicifolius, Tamarix troupii, Excoecaria agallocha, Myriostachya wightiana, Phoenix<br />

paludosa, etc. are found in denuded condition. At places old stumps <strong>of</strong> Avicennia sp. <strong>and</strong> Heritiera fomes are reminiscent<br />

<strong>of</strong> the existence <strong>of</strong> past mangrove vegetation. In mud flats, Suaeda maritima, Suaeda monoica, Sesuvium portulacastrum<br />

<strong>and</strong> Fimbristylis ferruginea are common elements. Recently, efforts have been made by State Forest Department <strong>and</strong><br />

M.S. Swaminathan Research Foundation, to introduce a number <strong>of</strong> species i.e., Avicennia <strong>of</strong>ficinalis, Sonneratia<br />

apetala, Aegiceras corniculatum, Ceriops dec<strong>and</strong>ra, Bruguira gymnorrhiza, Rhizophora apiculata, Avicennia marina,<br />

etc. in the form <strong>of</strong> plantation. In total, there are 12 true mangroves <strong>and</strong> 4 mangrove associates are present in Devi river<br />

mouth.<br />

Mangroves <strong>of</strong> Chilika Lake : The typical mangroves have disappeared from the fringes <strong>of</strong> the Chilika lake <strong>and</strong> its<br />

adjoining regions. Only mangrove associates <strong>and</strong> transitory taxa like Aegiceras corniculatum, Azima tetracantha,<br />

Salvadora persica, Cressa cretica, etc. are found at places. However, species like Clerodendrum inerme, Excoecaria<br />

agallocha, etc. are reported by Narayan swami <strong>and</strong> Cater (1922) could not be traceable at present. About 10 ha <strong>of</strong> l<strong>and</strong><br />

near Sipakuda <strong>and</strong> adjoining area have been planted with species i.e., Rhizophora apiculata, Avicennia marina, A.<br />

alba, A. <strong>of</strong>ficinalis <strong>and</strong> K<strong>and</strong>elia c<strong>and</strong>el by Forest Department <strong>of</strong> Orissa.<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

Mangroves <strong>of</strong> Orissa did not receive adequate protection in the past. Bhitarkanika forest area was under the control <strong>of</strong><br />

the erstwhile Zamindari Forests <strong>of</strong> Kanika Raj till 1951. On abolition <strong>of</strong> Zamindari system the management <strong>of</strong> mangrove<br />

forests was vested on Government <strong>of</strong> Orissa. At present, mangroves <strong>of</strong> Bhitarkanika, Mahanadi <strong>and</strong> Devi river mouth are<br />

being managed by the Mangrove Forest Division, Rajnagar, mangroves <strong>of</strong> Subarnarekha, <strong>and</strong> Budhabalanga are<br />

managed by Baripada Forest Division <strong>and</strong> mangroves planted in Chilika are being managed by Chilika Forest Division.<br />

Due to reclamation <strong>of</strong> mangrove forests for settlement <strong>of</strong> the immigrants, paddy cultivation, prawn culture, overexploitation<br />

<strong>of</strong> woody mangroves, establishment <strong>of</strong> port <strong>and</strong> factories the mangrove forests have been denuded in most<br />

part <strong>of</strong> the state. However, in recent years much effort is being made by State Forest Department, Government <strong>of</strong> Orissa<br />

not only to conserve mangrove forests but also to restore the degraded mangrove areas. Apart from the Forest Department,<br />

certain NGOs such as M. S. Swaminathan Research Foundation are also involved in conservation <strong>and</strong> restoration <strong>of</strong><br />

mangroves in the state. In view <strong>of</strong> much devastation <strong>of</strong> super cyclone that hit Orissa coasts during 29 <strong>and</strong> 30 November<br />

1999, the ecological role <strong>of</strong> mangroves has been realized much more than ever before <strong>and</strong> more emphasis has been<br />

laid on protection <strong>of</strong> this fragile forest ecosystem.<br />

<strong>Plants</strong> <strong>of</strong> High Conservation Significance<br />

The tropical dry evergreen forests are among the least known <strong>and</strong> unique vegetation types confined to a few localities<br />

in the world. These forests are reported to occur in Antigua, Bahamas, British Guiana, Jamaica, Trinidad <strong>and</strong> Tobago<br />

in Tropical America; Ethiopian highl<strong>and</strong>s, Tanzania <strong>and</strong> Zambia in Africa; Thail<strong>and</strong>, Sri Lanka <strong>and</strong> Corom<strong>and</strong>el coast<br />

<strong>of</strong> Peninsular <strong>India</strong> in Asia. There are no unified features for this rare <strong>and</strong> unique forest type <strong>and</strong> it has been chosen<br />

based on local climatic, biotic <strong>and</strong> edaphic factors, which influence the physiognomy, st<strong>and</strong> structure, species<br />

composition, <strong>and</strong> dynamics.<br />

Champion & Seth (1968) recognized a zone <strong>of</strong> tropical dissymmetric climate along east coast <strong>of</strong> southern <strong>India</strong> where<br />

climax vegetation is Tropical Dry Evergreen Forest (TDEF). This type <strong>of</strong> forest occurs in patches along the Corom<strong>and</strong>el<br />

coast that extends for about 80-100 km inl<strong>and</strong> (Mani 1974). These forests are typically low at 9 to 12 m high with<br />

continuous canopy <strong>and</strong> evergreen species having small, coriaceous leaves. Boles <strong>of</strong> the trees are short with spreading<br />

crowns with some deciduous emergents, without marked differentiation <strong>of</strong> canopy layers. Floristically, it is distinguished<br />

by a fair representation <strong>of</strong> characteristic <strong>and</strong> preferential species peculiar to this type (Meher-Homji 1974). Venkateswaran<br />

& Parthasarathy (2005) described the TDEF as short statured, largely three-layered evergreen forest with a sparse <strong>and</strong><br />

patchy ground flora. This author has been conducting ecological studies on the TDEF for a decade documenting<br />

plant species diversity, resource use pattern <strong>and</strong> conservation status covering as many as 75 sites in Pondicherry<br />

(11°562 N <strong>and</strong> 79°53' E), Villupuram (11°93' N 79°48' E), Cuddalore (11°43' N <strong>and</strong> 79°49' E) <strong>and</strong> Pudukottai (10°23'<br />

N <strong>and</strong> 78°52' E) areas on the Corom<strong>and</strong>el coast (Plate 29). The areal extent <strong>of</strong> TDEF sites studied ranged from 0.5 ha<br />

to ~10 ha. In reality, most <strong>of</strong> the <strong>India</strong>n TDEFs, with the exception <strong>of</strong> two large areas, namely the Kurumbaram section<br />

<strong>of</strong> the Marakanam Reserve Forest <strong>and</strong> the Point Calimere Wildlife Sanctuary, occur as patches <strong>of</strong> forest dotted along<br />

the Corom<strong>and</strong>el Coast, <strong>and</strong> invariably protected as “sacred groves” based on the religious belief <strong>of</strong> the local people.<br />

This unique dry evergreen forest is relatively under-studied on aspects <strong>of</strong> structural <strong>and</strong> functional ecology, as compared<br />

to the tropical wet evergreen forests.<br />

Biophysical Features<br />

The Corom<strong>and</strong>el coast receives much <strong>of</strong> rainfall during the northeast monsoon (October-December), while southwest<br />

monsoon (June to September) is very little <strong>and</strong> inconsistent. The mean annual rainfall recorded at three major towns<br />

viz., Pondicherry, Cuddalore, <strong>and</strong> Pudukottai are 1,282, 1,079 <strong>and</strong> 1,033 mm respectively. The dry season lasts for six<br />

months (January to June), <strong>and</strong> monthly average rainfall during rest <strong>of</strong> the months is less than 60 mm. Mean annual<br />

maximum <strong>and</strong> minimum temperatures are 32.58°C <strong>and</strong> 24.51°C in Pondicherry, 22.75°C <strong>and</strong> 33.64°C in Cuddalore,<br />

<strong>and</strong> 33.4°C <strong>and</strong> 25.4°C in Pudukottai. General physiognomy <strong>of</strong> TDEFs <strong>and</strong> characteristic plant species are featured<br />

(Plate 29).<br />

Systematic study <strong>of</strong> vascular plants at 75 TDEF sites in the Corom<strong>and</strong>el coast yielded 149 woody species belonging to<br />

122 genera <strong>and</strong> 49 families. Of the 149 woody plant species 102 are trees, 47 lianas, <strong>and</strong> three are characteristic native<br />

herbs (Parthasarathy et al. 2008) which include the widely-distributed, colony-forming Sansevieria roxburghiana, fairly<br />

distributed Ecbolium viride, <strong>and</strong> the rare Amorphophallus sylvaticus. Dominant families in <strong>India</strong>n TDEFs include<br />

Euphorbiaceae, Rubiaceae with 11 species each, followed by Capparaceae, Mimosaceae, Fabaceae <strong>and</strong> Moraceae<br />

with 8 species each, while Alangiaceae, Barringtoniaceae <strong>and</strong> Burseraceae are represented by single species.<br />

Among various Life-forms, Phanerophytes (trees) are dominant representing 102 species (68% <strong>of</strong> the total) species,<br />

while lianas formed 32% (47 species). Earlier floral inventories in 12 one ha TDEF permanent plots (Parthasarathy &<br />

Karthikeyan 1997; Venkateswaran & Parthasarathy 2003; Mani & Parthasarathy 2005; Reddy & Parthasarathy 2003,<br />

2007; Anbarashan & Parthasarathy 2008) resulted in 86 tree species with a range <strong>of</strong> 19 to 35 species. An ubiquitous<br />

tree, Memecylon umbellatum, was the most dominant species, accounting for 32% <strong>of</strong> tree density, followed by Tricalysia<br />

sphaerocarpa (10.5%) <strong>and</strong> Pterospermum canescens (9.7%) in the TDEF. A total <strong>of</strong> 44 liana species were recorded<br />

with a range <strong>of</strong> 21-29 species ha -1 in the eight one ha plots. Among lianas, Combretum albidum (19.2%), Strychnos<br />

minor (14%), <strong>and</strong> Reissantia indica (6.5%) were predominant species.<br />

Out <strong>of</strong> 149 species, 75 are evergreen (50%), followed by deciduous (45 species, 30%) <strong>and</strong> brevi-deciduous species<br />

[species with brief deciduous period followed by synchronous leaf-flushing, e.g., Pterospermum canescens (29 species;<br />

20%). Analysis <strong>of</strong> qualitative reproductive traits <strong>of</strong> TDEF species (Selwyn & Parthasarathy 2006) reveals that many<br />

species had rotate-type, white-colored, scented flowers with nectar <strong>and</strong> pollen as rewards. Drupe <strong>and</strong> berry were the<br />

common fruit types <strong>and</strong> were found in black <strong>and</strong> red color, respectively. A strong association between the qualitative<br />

reproductive traits <strong>and</strong> pollination <strong>and</strong> dispersal spectrum among the TDEF species has been demonstrated (Selwyn<br />

& Parthasarathy 2006).<br />

The bioresource potential, especially the medicinal importance <strong>of</strong> TDEF species, deserves detailed documentation<br />

within several unstudied sites. In addition to 75 TDEF sites studied, many more sites remain unexplored. The current<br />

underst<strong>and</strong>ing <strong>of</strong> aut-ecology <strong>and</strong> reproductive biology <strong>of</strong> most <strong>of</strong> the dry evergreen species is still at infant stage. The<br />

promising areas <strong>of</strong> future research include: (i) Reproductive biology <strong>of</strong> important species such as Pterospermum<br />

xylocarpum, Casearia elliptica, Aglaia elaeagnoidea, Tiliacora acuminate, Strychnos minor, Sansevieria roxburghiana<br />

<strong>and</strong> Amorphophallus sylvaticus, (ii) Genetic diversity <strong>of</strong> polymorphic species such as Memecylon umbellatum,<br />

Pterospermum xylocarpum, (iii) Bioresource potential <strong>of</strong> various medicinal plants, typically found within TDEF, (iv)<br />

Mass multiplication <strong>of</strong> multi-purpose species such as Sansevieria roxburghiana (used in the treatment <strong>of</strong> ear diseases<br />

<strong>and</strong> cough, yields silky fiber, leaf mucilage used locally as face cream, an effective s<strong>and</strong> binder <strong>and</strong> a hedge plant),<br />

Ormocarpum cochinchinensis (for bone setting) <strong>and</strong> Amorphophallus sylvaticus (for piles), to name a few, (v) Phytochemical<br />

screening <strong>of</strong> important species such as Memecylon umbellatum, Trichosanthes tricuspidata, Cassytha filiformis,<br />

Cissus vitiginea, Sarcostemma acidum, Atalantia monophylla, <strong>and</strong> Jasminum angustifolium among others. Threats to<br />

TDEFs include forest fragmentation, l<strong>and</strong> use change, encroachments for agriculture, soil removal, over grazing by<br />

domestic livestock, <strong>and</strong> extraction <strong>of</strong> fuel wood <strong>and</strong> medicinal plants.<br />

Conservation <strong>of</strong> TDEF patches <strong>and</strong> representative floral elements is <strong>of</strong> utmost priority considering the restricted<br />

geographical distribution <strong>and</strong> unique features. It is high time that the conservation agencies, academicians <strong>and</strong> nongovernmental<br />

organizations come together <strong>and</strong> draw a conservation action plan involving local communities.<br />

Introduction<br />

Since the time <strong>of</strong> Darwin <strong>and</strong> Wallace, oceanic isl<strong>and</strong>s have been recognized to be <strong>of</strong> great significance in studies <strong>of</strong><br />

organismic diversity, biogeography <strong>and</strong> evolution. Isolated from the main l<strong>and</strong>s by vast expanses <strong>of</strong> water <strong>and</strong> with<br />

relatively little or no human interference, they provide ideal sites for the study <strong>of</strong> evolution, speciation <strong>and</strong> adaptive<br />

radiation. Such isl<strong>and</strong> groups display enormous variety <strong>of</strong> biota <strong>and</strong> more importantly, with a sizeable endemic component.<br />

However, most <strong>of</strong> these isl<strong>and</strong>s have been subject to overexploitation <strong>of</strong> natural resources <strong>and</strong> ill planned developmental<br />

activities leading to widespread destruction <strong>of</strong> natural habitats <strong>and</strong> loss <strong>of</strong> biodiversity, which is not yet fully understood<br />

<strong>and</strong> catalogued.<br />

Andaman & Nicobar (A&N) Isl<strong>and</strong>s, situated between 6 o 45' to 13 o 41' N latitudes <strong>and</strong> 92 o 12' to 93 o 57' E longitudes (Fig<br />

- 1), form the largest archipelago in the Bay <strong>of</strong> Bengal, consisting <strong>of</strong> 306 isl<strong>and</strong>s <strong>and</strong> 206 rocks <strong>and</strong> rocky outcrops.<br />

Often described as ‘Isl<strong>and</strong>s <strong>of</strong> the marigold sun’, they were known as ‘Kalapani’ because <strong>of</strong> their having been an area<br />

<strong>of</strong> penal settlement during British rule. These groups <strong>of</strong> isl<strong>and</strong>s are projections <strong>of</strong> a long narrow submarine range <strong>of</strong><br />

mountains, with only the peaks being visible above the sea. Geologically these isl<strong>and</strong>s are quite young in age, probably<br />

formed in upper Mesozoic (ca 100 million years ago). This mountain range has a narrow deep oceanic furrow on the<br />

western boundary that abuts on the main continental plate on the west. The total geographical area <strong>of</strong> these isl<strong>and</strong>s is<br />

8,249 km 2 , coast line <strong>of</strong> 1,962 kms. The northern group <strong>of</strong> isl<strong>and</strong>s, the Andaman group, is 6,408 km 2 <strong>and</strong> the Nicobar<br />

group is 1,841 km 2 . This large archipelago is separated from mainl<strong>and</strong> <strong>India</strong> by almost 1000 kms; the nearest l<strong>and</strong>mass<br />

in the north is Myanmar, roughly 280 km north <strong>of</strong> L<strong>and</strong>fall Isl<strong>and</strong>, the northern-most isl<strong>and</strong> is the Andaman Group. The<br />

closest l<strong>and</strong>mass to the Great Nicobar Isl<strong>and</strong> is Sumatra, 145 km south.<br />

The Great Andaman group <strong>of</strong> isl<strong>and</strong>s comprises North, Middle <strong>and</strong> South Andaman Isl<strong>and</strong>s, with Baratang Isl<strong>and</strong><br />

situated between Middle <strong>and</strong> South Andaman Isl<strong>and</strong>. Andaman group is 352 km in length, its extreme width, however<br />

is nowhere more than 52 kms. Ritchie’s Archipelago, a group <strong>of</strong> isl<strong>and</strong>s, is located east <strong>of</strong> Middle Andaman while<br />

Labyrinth group <strong>of</strong> isl<strong>and</strong>s lies southwest <strong>of</strong> South Andaman (Plate 30). The Little Andaman is located 55 km south <strong>of</strong><br />

South Andaman, across the Duncan passage. The l<strong>and</strong> area <strong>of</strong> 6408 km 2 <strong>of</strong> the Andaman Group constitutes almost<br />

90% (5629 km 2 ), as reserve or protected forest <strong>of</strong> which 36% is Tribal Reserve. The elevation in the Andamans ranges<br />

from 0-732m, the Saddle Peak in North Andaman being the highest.<br />

The Nicobar group is spread over an area <strong>of</strong> 1,841 km 2 <strong>of</strong> which, 1,542 km 2 area falls under recorded forests. The<br />

Nicobars are separated from the Andamans by the 10 0 Channel, a wide gap <strong>of</strong> 160 km with heavy tidal flows, making<br />

sea transport by small boasts difficult. The Nicobars consists <strong>of</strong> 24 isl<strong>and</strong>s in three distinct clusters <strong>of</strong> which 12 are<br />

inhabited having 170 villages <strong>and</strong> hamlets. The Northern Group consists <strong>of</strong> Car Nicobar, Batti Malv <strong>and</strong> the Central or<br />

the Nancowry Group. The latter includes Car Nicobar, Tillanchong, Chowra, Teressa, Bompoka, Trinkat, Kamrota,<br />

Katchal <strong>and</strong> Nancowry isl<strong>and</strong>s. The southern group consists <strong>of</strong> the two large isl<strong>and</strong>s Little <strong>and</strong> Great Nicobar, together<br />

with Pigeon, Megapode, Kondul, Pilo Milo, Menchal, Treis, Trak <strong>and</strong> Meroe Isl<strong>and</strong>s. The entire Nicobar is a Tribal<br />

Reserve <strong>and</strong> has four sanctuaries. An area <strong>of</strong> 885 km 2 in Great Nicobar Isl<strong>and</strong> is designated as the Great Nicobar<br />

Biosphere Reserve <strong>and</strong> two other areas within it as national parks (Jayaraj & Andrews, 2005). The climate is humid<br />

tropical. The average annual rainfall varies from 1,400 mm to 3,000 mm <strong>and</strong> average annual temperature varies from<br />

24 o C to 28 o C.<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

The A&N isl<strong>and</strong>s are the homel<strong>and</strong> <strong>of</strong> six tribal communities, viz., Great Andamanese, Onge (numbering only 97),<br />

Jarwa, Sentinels (numbering 100 – 150). Shompen <strong>and</strong> Nicobarese. However, there is a distant racial difference<br />

between the Andaman tribes <strong>and</strong> their counter parts in the Nicobars. The former four are Negrito, while the latter are<br />

Mongoloid. The Nicobarese are well integrated <strong>and</strong> assimilated to the <strong>India</strong>n mainstream <strong>and</strong> the Shompen, who are<br />

still shy <strong>and</strong> avoid any interaction with the outsiders but they are not particularly hostile. The Onge, Jarwas <strong>and</strong> Great<br />

Andamanese have accepted outside intervention <strong>and</strong> are being rehabilitated by the A&N Administration. However, the<br />

Sentinels are still hostile.<br />

Vegetation<br />

The A&N has a rich wealth <strong>of</strong> vegetation. While describing the vegetation <strong>of</strong> these isl<strong>and</strong>s Parkinson (1923) wrote “from<br />

the water’s edge to tops <strong>of</strong> the highest hills, the isl<strong>and</strong>s are nearly every where densely wooded”. According to Balakrishnan<br />

& Ellis (1996) <strong>and</strong> Rao (1999), the climatic climax <strong>of</strong> the isl<strong>and</strong>s is typically the Tropical Lowl<strong>and</strong> Rain Forest, which<br />

is in a state <strong>of</strong> equilibrium, seemingly undisturbed, influenced by warm <strong>and</strong> wet conditions. These forests are floristically<br />

the richest, highly complex, most exuberantly developed, though somewhat influenced by altitude <strong>and</strong> intensity <strong>of</strong><br />

monsoons. The higher reaches are also affected by high wind velocity, causing dessication, exhibiting stunted, scrublike<br />

vegetation, called Hill-top vegetation as seen on Saddle Peak in North Andamans, <strong>and</strong> mount Thuiller in Great<br />

Nicobar. Kurz (1876) while working on the Nicobar group <strong>of</strong> isl<strong>and</strong>s has grouped the vegetation <strong>of</strong> this area into<br />

following categories: (i) Mangrove forests; (ii) Beach forests; (iii) Tropical Forests, (iv) Grass-heaths <strong>of</strong> Car Nicobar <strong>and</strong><br />

Kamrota isl<strong>and</strong>s; (v) Marine vegetation with some sea grasses such as Halophia ovalis <strong>and</strong> Enhalus acoroides.<br />

Champion & Seth (1968) treated the forests <strong>of</strong> A&N Isl<strong>and</strong>s under 11 types, viz. (i) Giant evergreen forest, (ii) Andaman<br />

tropical evergreen forest, (iii) Southern hill-top tropical evergreen forest, (iv) Cane brakes, (v) Wet bamboo brakes, (vi)<br />

Andaman semi evergreen forest, (vii) Andaman moist deciduous forest, (viii) Andaman secondary moist deciduous<br />

forest, (ix) Littoral forest, (x) Tidal swamp forest, <strong>and</strong> (xi) Submontane hill valley swamp forest.<br />

According to Balakrishnan & Ellis (1996) the configuration <strong>and</strong> composition <strong>of</strong> some <strong>of</strong> the above major types <strong>of</strong> forests<br />

can be summarized as follows: The giant evergreen forests are typically climatic climax, where optimum conditions<br />

are prevalent. Characteristically the top canopy, though irregular, is almost covered. The soil is deep alluvial <strong>and</strong> able<br />

to retain the water content <strong>of</strong> the abundant rainfall <strong>of</strong> about 300 cm for long periods. Several species <strong>of</strong> Dipterocarpus<br />

viz., D. alatus, D. gracilis, D. incanus, D. turbinatus var. <strong>and</strong>amanica <strong>and</strong> Hopea odorata are found here. The second<br />

storey comprises Baccaurea sapida, Sideroxylon longipetiolatus, Endospermum malaccense, Artocarpus gomezianus,<br />

Myristica glaucesens <strong>and</strong> Buchanania platyneura.<br />

The Andaman tropical evergreen forests are less luxuriant, the top storey being irregular <strong>and</strong> the canopy not complete.<br />

They occur at the top <strong>of</strong> hills with elements <strong>of</strong> moist deciduous type on the slopes. Many species <strong>of</strong> Dipterocarpus<br />

occur here among which D. kerrii is prominent, intermixed with Artocarpus chaplasha, Panchonia <strong>and</strong>amanica, Hopea<br />

odorata, Sideroxylon longipetiolatum, associated with Garcinia <strong>and</strong>amanica, Myristica <strong>and</strong>amanica, M. glaucescens<br />

<strong>and</strong> Baccaurea sapida. The climbers include Gnetum sc<strong>and</strong>ens, Ancistrocladus tectorius, the climbing bamboo<br />

Dinochloa sc<strong>and</strong>ens var. <strong>and</strong>amanica, Artabotrys speciosus, Calamus longisetus, C. palustris, C. pseudorivalis, etc. the<br />

last three making cane-brakes at disturbed places having exposed canopy.<br />

The Andaman Semi-evergreen forests occur on immature, alluvial soil, distributed in the main valleys <strong>of</strong> the Andamans<br />

forming some <strong>of</strong> the densest forests. The top layer mainly includes Dipterocarpus alatus, D. pilosus, Petrocymbium<br />

tinctorium, Sterculia campanulata, Terminalia bialata, Calophyllum soulattri, Atrocarpus lakoocha, A. chaplasha <strong>and</strong><br />

Pterocarpus dalbergioides intermixed with Dillenia pentagyna, Pometia pinnata, Litsea panamonja, Xanthophyllum


Endemic <strong>Plants</strong> <strong>of</strong> Andaman <strong>and</strong><br />

Nicobar Isl<strong>and</strong>s<br />

<strong>and</strong>amanicum, Mangnolia <strong>and</strong>amanica, Garcinia <strong>and</strong>amanica, Caryota mitis <strong>and</strong> Parishia insignis. Climbers include<br />

Dinochloa sc<strong>and</strong>ens var. <strong>and</strong>amanica, Combretum latifolium, Thunbergia fragrans <strong>and</strong> Calamus spp. Because <strong>of</strong> many<br />

good timber yielding plants, these forests are economically the most important.<br />

The Andaman moist deciduous forests are with leaf-shedding plants reaching a height <strong>of</strong> about 45 m, attaining large<br />

girth <strong>and</strong> <strong>of</strong>ten predominantly buttressed. The second storey includes some evergreen species. Shrubby climbers are<br />

common, including canes. These are commonly met with in the Andaman Isl<strong>and</strong>s, rarely so in the Nicobars. The hard<br />

coarse grained s<strong>and</strong>stone forms the underlying rock with shale <strong>and</strong> conglomerate. The soil is rather shallow <strong>and</strong><br />

s<strong>and</strong>y loamy. The characteristic species include: Pterocarpus dalbergioides, Lagerstroemia hypoleuca, Chukrasia<br />

tabularis, Sterculia alata, Pterocymbium tinctorium, Terminalia bilata, T. procera, etc. The second storey comprises<br />

Adenanthera pavonina, Dillenia pentagyna, Lannea corom<strong>and</strong>elica, Diospyros marmorata, etc., followed by similar<br />

trees like Murraya paniculata, Pterospermum alatum, Ixora gr<strong>and</strong>ifolia, Atlantia monophylla, Antiaris toxicaria, Artocarpus<br />

chaplasha, Canarium euphyllum, Spondias mangifera, Garuga pinnata, Gyrocarpus americanus, Zanthoxylum<br />

budrunga, etc.<br />

The Andaman secondary moist deciduous forests comprise elements intermixed with preceeding forest, <strong>and</strong> they are<br />

essentially composed <strong>of</strong> two canopies, the upper one comprising Bombax ceiba, Pterocymbium tinctorium, Terminalia<br />

bialata, Tetrameles nudiflora, Parishia insignis, etc. <strong>and</strong> the lower canopy comprising Pterocarpus dalbergioides,<br />

Lagerstroemia hypoleuca, Albizia lebbeck, Adenanthera pavonina, Planchonia <strong>and</strong>amanica, Diploknema butyracea,<br />

etc. This type is more regenerated secondary forests, where semi-evergreen type existed previously.<br />

The Southern hill-top tropical evergreen forests are to be found in some <strong>of</strong> the high hill tops <strong>of</strong> these isl<strong>and</strong>s, i.e., Saddle<br />

Peak <strong>of</strong> North Andamans <strong>and</strong> Mount Thuiller <strong>of</strong> Great Nicobar Isl<strong>and</strong>. These hills are subject to high velocity wind with<br />

heavy rainfall <strong>of</strong> over 450 cm per year associated with high humidity during the monsoon season. The trees <strong>of</strong> these<br />

forests are stunted <strong>and</strong> surrounded by wet evergreen forests at lower hill slopes. The common trees include Dipterocarpus<br />

costatus, Phyllanthus <strong>and</strong>amanica, Memecylon collinum, M. caeruleum, Psychotria balakrishnaii, Grewia ind<strong>and</strong>amanica,<br />

Canarium manii, Mesua ferrea, Hopea <strong>and</strong>amanica, Cratoxylum formosum, Euphorbia epiphylloides, Chionanthus<br />

sumatranus, Crytocarya ferrarsi, Phoenix <strong>and</strong>amanica <strong>and</strong> the climbing bamboo Dinochloa sc<strong>and</strong>ens var. <strong>and</strong>amanica<br />

<strong>and</strong> Schizostachyum <strong>and</strong>amanicum making impenetrable thickets with entangled <strong>and</strong> matted stems. The ground layer<br />

has grasses such as Oryza ind<strong>and</strong>amanica, Imperata cylindrica, Heteropogon contortus, Chrysopogon aciculatus,<br />

associated with several species <strong>of</strong> mosses, Sonerila sp., Utricularia exoleta <strong>and</strong> Rostellularia procumbens. The rocks<br />

<strong>and</strong> boulders here are usually covered by dense moss, especially during monsoon season bearing amidst them the<br />

rare North east <strong>India</strong>n orchids Porpax meirax <strong>and</strong> Ascocentrum ampullaceum.<br />

Parkinson (1923), while dealing with only Andaman Isl<strong>and</strong>s, expounds the main forest types under: (i) Mangrove<br />

forests, (ii) Littoral forests, (iii) Evergreen forests, (iv) Deciduous <strong>and</strong> semideciduous forests, <strong>and</strong> (v) Forests <strong>of</strong> the<br />

parched <strong>and</strong> shallow-soiled slopes <strong>of</strong> high hills as at Saddle Peak, the Cladius Range <strong>and</strong> Mt. Farrington in the Middle<br />

Andaman <strong>and</strong> Mt. Ford on Rutl<strong>and</strong> Isl<strong>and</strong>. Thothathri (1960) treats the Andaman forests under seven types including<br />

vegetation <strong>of</strong> the cleared l<strong>and</strong>s <strong>and</strong> open areas <strong>and</strong> marine vegetation. Saldanha (1989) demarcates six forest types in<br />

the Andamans: (i) Giant Andaman Evergreen, (ii) Andaman Tropical Evergreen, (iii) Andaman Moist Deciduous forests,<br />

(iv) Andaman Hill-top Evergreen, (v) Littoral forests <strong>and</strong> (vi) Mangrove forests. He also calls Bamboo <strong>and</strong> Cane brakes<br />

as local variations.<br />

While dealing with the natural vegetation <strong>of</strong> the entire A&N Isl<strong>and</strong>s, Balakirshnan (1977, 1989) broadly classified the<br />

vegetation into 2 major groups consisting <strong>of</strong> eight types, giving importance not only to forests but also to the other types<br />

occurring in various ecological zones. According to him the vegetation <strong>of</strong> these isl<strong>and</strong>s can be broadly classified as<br />

tropical evergreen with minor variations from north to south depending upon rainfall, type <strong>of</strong> soil <strong>and</strong> degree <strong>of</strong> salinity<br />

in the soil. Based on the proximity to the sea <strong>and</strong> salinity <strong>of</strong> the soil, the vegetation can be placed into two major groups,<br />

i.e. Littoral <strong>and</strong> Inl<strong>and</strong> types, each further subdivided as follows:<br />

A. Littoral: (i) Submerged vegetation, (ii) Mangrove vegetation (iii) Str<strong>and</strong> vegetation, (iv) Tidal or swamp forests.<br />

B. Inl<strong>and</strong>: (i) Evergreen forests, (ii) Deciduous forests, (iii) Grassl<strong>and</strong>s, (iv) Aquatic vegetation.<br />

Floristically, A&N Isl<strong>and</strong>s shows close affinities with Indo – Chinese <strong>and</strong> Indo – Malayan region. Presence <strong>of</strong> over 2,000<br />

indigenous <strong>and</strong> 500 non – indigenous angiosperm species within a l<strong>and</strong> mass <strong>of</strong> 8,290 km 2 is a significant feature <strong>of</strong><br />

the isl<strong>and</strong>s, making them a cynosure not only for plant taxonomists but also for conservationists. Among the nonendemic<br />

angiosperms, about 40% are found in mainl<strong>and</strong> <strong>India</strong>. As regards Pteridophyes, 120 species are known<br />

under 36 families. Nearly 365 species are considered as ‘threatened’ while 40 species have been listed under Red<br />

Data Book <strong>of</strong> <strong>India</strong>n <strong>Plants</strong>. More than 600 species <strong>of</strong> exotic plants have been introduced to these isl<strong>and</strong>s, many <strong>of</strong><br />

them being aggressive <strong>and</strong> invasive in nature, which pose serious threat to the native flora <strong>and</strong> fauna.<br />

Of about 2000 native angiosperms, 14% are endemic to these isl<strong>and</strong>s. At the generic level endemism is rather less with<br />

only three genera viz., Sphyranthera (Euphorbiaceae) with 2 species. Pubistylis (Rubiaceae) with one species <strong>and</strong><br />

Nicobariodendron (Celastraceae) with one species. Recently Garbyal et al. (2008), Naithani (2008) <strong>and</strong> Naithani et al.<br />

(2008) have mentioned some rare, endemic lesser known trees from the Isl<strong>and</strong>s. An updated list <strong>of</strong> endemic vascular<br />

plants from these isl<strong>and</strong>s is given in Table 1 (Plate 30).<br />

Today when the earth is in a state <strong>of</strong> biodiversity crunch, environmentalists are looking back through the ages to our<br />

ancestors, who had some indigenous ways to conserve nature. One <strong>of</strong> the traditional ways to conserve nature is the<br />

system <strong>of</strong> Sacred Groves (SGs). Sacred groves must be the first temple <strong>of</strong> worship in the world, made by primitive<br />

human societies to worship nature. If defined, the sacred groves are forest patches <strong>of</strong> varying size, from a few trees to<br />

several hectares. They are sometimes dedicated to some deity or ancestral spirit <strong>and</strong> are sanctified to the extent that<br />

they become divine <strong>and</strong> cutting them becomes a taboo. Though this tradition has now been receded to remote villages<br />

<strong>and</strong> in some cases to folklores <strong>and</strong> folk tales, they are quite relevant even today as they always have been. According to<br />

famous folklorist <strong>of</strong> 20 th century Charlotte Burne, the tribes <strong>of</strong> Votiaks <strong>of</strong> eastern Russia sing that the woods are always<br />

sacred from where not a single tree may cut down or else the God <strong>of</strong> the woods will avenge the injury. Like wise in many<br />

parts <strong>of</strong> the world trees were regarded as being divine <strong>and</strong> the place having these trees was regarded as sacred groves.<br />

Such groves were <strong>of</strong>ten located around homes <strong>and</strong> surrounding the village <strong>and</strong> to break even a twig <strong>of</strong>f was a sacrilege<br />

(Frazer 1919). The supernatural power <strong>of</strong> some water bodies like healing <strong>and</strong> curing some ailments in different parts<br />

<strong>of</strong> the world has been documented by many workers (Olsen 2004, Tarasov 2003). Very <strong>of</strong>ten sacred groves were<br />

considered as having infinite magical power to grant punishment or to carry out miracles (Philpot & Mac Millan 1897,<br />

Parish 2005, Altman 2000).<br />

Role <strong>of</strong> Sacred Groves<br />

Besides social, cultural <strong>and</strong> economic services, the sacred groves have the potential to serve as gene pool <strong>and</strong> may<br />

help to maintain ecological balance. National Forest Policy (1988) states that the SGs are the last remnants <strong>of</strong> natural<br />

forests <strong>and</strong> are extremely valuable store house <strong>of</strong> biodiversity. Larger sacred groves can harbour high species richness<br />

<strong>and</strong> they play a significant role in in situ conservation <strong>of</strong> plants. Sometimes SGs give refugia to rare, endangered <strong>and</strong><br />

endemic species. The SGs preserve the micro-climate within its area <strong>and</strong> increase nutrient cycling; it also recharges<br />

aquifers <strong>and</strong> act as primary source <strong>of</strong> perennial streams. Keeping in view the value <strong>of</strong> SGs, researchers have given<br />

various names to the SGs, such as Refugia for rare <strong>and</strong> threatened species, Laboratory <strong>of</strong> environmentalists,<br />

Compensation for carbon emissions (Carbon sink), Recreational <strong>and</strong> spiritual point, Reservoir <strong>of</strong> medicinal plants,<br />

Socially valued ecosystem, Heritage <strong>of</strong> cultural <strong>and</strong> traditional knowledge. If harnessed properly these groves along<br />

with the indigenous wisdom <strong>of</strong> its community can serve as multi-functional units <strong>of</strong> conservation.<br />

Sacred Groves in Uttarakh<strong>and</strong><br />

The rural communities in Uttarakh<strong>and</strong> also have retained the tradition <strong>of</strong> worshipping sacred places such as Bugiyals<br />

(sacred alpine meadows), Dev Vans, etc. Mostly a few individual trees <strong>of</strong> a species e.g., Cedrus, Cupresuss, Pinus <strong>and</strong><br />

Quercus or single tree <strong>of</strong> some importance in the vicinity <strong>of</strong> the village are sanctified along with small temple. Such<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

places are locally known as ‘Thans’. They are well preserved lush green patches. Sometimes individual <strong>of</strong> trees that<br />

attain giant size are considered sacred as they are believed to witness the changing history <strong>of</strong> the place <strong>and</strong> hence<br />

dedicated to local deities. For example, Deodar (Cedrus deodara) tree in Jageshwar (8.3m girth <strong>and</strong> 30m height),<br />

Noble cypress (Cupressus torulosa) tree in Devi Anusuea temple (6.25m girth <strong>and</strong> 32m height), Silk cotton (Bombax<br />

ceiba) tree near Sitarganj (12m girth <strong>and</strong> 28m height), Mulberry (Morus serrata) tree in Joshimath (18m girth <strong>and</strong><br />

>5096 yrs old).<br />

Though, detailed surveys <strong>of</strong> sacred groves have not been done in Uttarakh<strong>and</strong> so far, some <strong>of</strong> the well known sacred<br />

groves which support either an ecosystem or single species conservation are dedicated to a number <strong>of</strong> deities like<br />

Bhadraj (the deity who is known to teach cattle rearing), Mahasu, Shakumbari <strong>and</strong> Tarkeshwar Mahadev. Other places<br />

such as Patal Bhubaneshawar (rocks <strong>and</strong> caves with calcareous tufa), Garanath, Binsar, Mayadevi Ashram <strong>and</strong><br />

Narayan Ashram harbor various floral <strong>and</strong> faunal elements, some <strong>of</strong> which could be rare, threatened <strong>and</strong> endemic<br />

species.<br />

Most <strong>of</strong> the sacred groves in the state are located in Deodar zone or dominated by this species, which support various<br />

medicinal plants. Taxus baccata subsp. wallichiana is one <strong>of</strong> the most important medicinal plants growing under its<br />

canopy in Jageshwar <strong>and</strong> hence protected, while outside the grove this species is under tremendous pressure. The<br />

sacred Deodar forest patches spread over 2-5 km 2 area <strong>and</strong> are devoted to various deities. Some examples <strong>of</strong> sacred<br />

Deodar forests include Jageshwar <strong>and</strong> Dhauladevi in Almora district, Tarkeshwar in Pauri district, Devalsari (temple<br />

devoted to a saint) in Tehri district, Hat-Kali <strong>and</strong> Chamunda in Pithoragarh district. Some times natural structures<br />

(caves <strong>and</strong> crevices) also enhance the value <strong>of</strong> forest patches, e.g., Patal-Bhuwaneshwar in Pithoragarh <strong>and</strong> Gauri<br />

Udiyar in Bageshwar districts. The famous deity Golu Devta <strong>of</strong> Kumaun region has several groves (Chitai, Ghorakhal,<br />

Gairar, Minar, Chamarkhan, Bari Goljyu) which are mostly under mixed pine-oak forests. Padiyar Devta, a well known<br />

local deity at 3400m altitude above Auli, Joshimath is seated under Quercus semecarpifolia forest, where the herders<br />

pray before entering the forest to safeguard their cattle from natural calamities <strong>and</strong> wild animals (Plate 31). Although,<br />

the groves have patchy distribution still they play a crucial role in maintaining biodiversity <strong>and</strong> provide protection to the<br />

local flora <strong>and</strong> fauna (Dhaila-Adhikari & Adhikari 2007).<br />

Sometimes the sacred places give refuge to the rare tree species as in case <strong>of</strong> Ch<strong>and</strong>hak temple <strong>of</strong> Pithoragarh. The<br />

‘Sweet Osmanthus’ (Osmanthus fragrans) tree, which is an evergreen small tree with lustrous medium sized leaves.<br />

The flowers are extremely fragrant <strong>and</strong> perfume the entire l<strong>and</strong>scape during winter to spring. Larger sacred groves<br />

also have their own micro-climate which increase nutrient cycling, recharge aquifers <strong>and</strong> act as primary source <strong>of</strong><br />

perennial streams. For example, Shikhareshwer SG in Gangolihat (Pithoragarh) where Deodar forest forms catchment<br />

for perennial water stream (Naula).<br />

In many groves villagers perform rituals <strong>and</strong> ceremonies to please the deity for well being <strong>and</strong> prosperity <strong>of</strong> the<br />

community. Sacred groves are the mirror image <strong>of</strong> cultural <strong>and</strong> economic set up <strong>of</strong> a community <strong>and</strong> their respect for<br />

nature. Some <strong>of</strong> the trees which are considered as sacred <strong>and</strong> worshiped in the state are Peepal (Ficus religiosa),<br />

Bargad (F. benghalensis), Bel (Aegle marmelos), Deodar (Cedrus deodara), Padam (Prunus cerasoides), Timur<br />

(Xanthoxylum alatum), Amla (Emblica <strong>of</strong>ficinalis), Mango (Mangifera indica), Neem (Azadirachta indica), Doob (Cynodon<br />

dactylon) <strong>and</strong> Banana (Musa paradisiaca). Peepal tree in the villages near Lohaghat is worshiped. These trees had<br />

been planted by the ancestors <strong>of</strong> the village <strong>and</strong> are still revered by their progeny. These trees are treated as family<br />

members <strong>and</strong> all the rituals, due to family members such as thread ceremony <strong>and</strong> marriage with some other religious<br />

trees as Mango <strong>and</strong> Aonla, are performed. In Kumaun region <strong>of</strong> Uttarakh<strong>and</strong> it is observed that the forest patches which

were under severe biotic pressure <strong>and</strong> over exploited have been dedicated to the local deity after a concent <strong>of</strong> the<br />

community e.g., Shyahi devi in Almora.<br />

There are a number <strong>of</strong> small SGs in Uttarakh<strong>and</strong>, but they have not been documented due to their small size. Hence,<br />

it is not possible for the forest department to take any action to protect such SGs. Likewise, several other states are still<br />

waiting to enlist the SGs. So far, no legal protection has been given to these groves, except at few places e.g., sites <strong>of</strong><br />

Archaeological Survey <strong>of</strong> <strong>India</strong> or where Forest Department is involved. In other places, its belief, taboo or fetishism<br />

which makes them inviolate. So, the institute <strong>of</strong> sacred groves is the cradle, where the faith <strong>and</strong> beliefs are nurtured<br />

together with the habitats <strong>and</strong> biodiversity.<br />

Threats <strong>and</strong> challenges<br />

The SGs are rapidly loosing their ground in many parts <strong>of</strong> <strong>India</strong> due to following reasons:<br />

• Erosion <strong>of</strong> traditional beliefs <strong>and</strong> rapid socio-economic advancement has led to the deterioration <strong>of</strong> sacred<br />

groves. Fading respect towards traditional knowledge among youngsters is one <strong>of</strong> the causes <strong>of</strong> concern,<br />

• Developmental projects such as roads, dams, highways <strong>and</strong> encroachment by people migrating from outside<br />

having no respect for traditional values,<br />

• Transformation <strong>of</strong> traditional worship <strong>of</strong> nature into formal Hindu practice, which is called Sanskritization like<br />

shifting the focus to idols than a simple stone, building temples which include clearing <strong>of</strong> the area.<br />

• Heavy tourism sometimes becomes a burden to SGs, if the tourists are not aware <strong>of</strong> the fragile aspect <strong>of</strong> the<br />

nature.<br />

• Fragmentation or split among families owning sacred groves.<br />

Way forward<br />

Progress <strong>and</strong> modernity not at all means avoiding the old customs <strong>and</strong> traditions. Therefore, the following aspects can<br />

be made for well being <strong>of</strong> SGs conservation.<br />

• Inventory, documentation <strong>and</strong> the status <strong>of</strong> SGs.<br />

• Revitalization <strong>of</strong> traditional culture, such as folk tales <strong>and</strong> folklores.<br />

• Incentives to the local communities for maintaining <strong>and</strong> restoring SGs.<br />

• Role <strong>of</strong> NGOs, Forest department <strong>and</strong> academia through community participation.<br />

32.0 Endemic Pteridophytes <strong>of</strong> <strong>India</strong>:<br />

Distribution <strong>and</strong> Threat Status<br />

<strong>India</strong> is extremely rich in the diversity <strong>of</strong> Pteridophytic flora due to its remarkable variation in eco-climatic conditions,<br />

soil types <strong>and</strong> altitude. Recent assessments reveal that about 900-1000 species <strong>of</strong> Pteridophytes occur in <strong>India</strong><br />

(Ch<strong>and</strong>ra et al. 2008). However, richness <strong>of</strong> flora is closely linked with palaeo-history <strong>and</strong> intermingling <strong>of</strong> flora with<br />

other regions. Incidentally, <strong>India</strong> has only about 5% <strong>of</strong> the Pteridophytes as endemic. The Himalayan <strong>and</strong> North Eastern<br />

Pteridophytic flora forms an integral part <strong>of</strong> the large Sino-Himalayan <strong>and</strong> S.E. Asian floristic zones. This is the reason<br />

for a low percent <strong>of</strong> endemism in Pteridophytes from these zones. In contrast, peninsular <strong>India</strong> <strong>and</strong> Isl<strong>and</strong>s have<br />

relatively higher percentage <strong>of</strong> endemics as they are insulated by the <strong>India</strong>n Ocean <strong>and</strong> other biogeographic barriers.<br />

The most authentic <strong>and</strong> foremost attempt to record the endemic Pteridophytes <strong>of</strong> <strong>India</strong> was made by Ch<strong>and</strong>ra (1982).<br />

He reported 96 species endemic to <strong>India</strong>. Later, Ch<strong>and</strong>ra & Kaur (1984) added 41 species to the previous list. Dhir &<br />

Saiki (1984) listed 58 species <strong>of</strong> ferns as endemic to the Himalaya, whereas Dixit (1984) listed 214 species <strong>of</strong> Pteridophytes<br />

endemic to <strong>India</strong>. Further information on the distribution <strong>of</strong> endemic Pteridophytes was provided by Bir (1987 & 1989).<br />

After that a phytogeographic analysis <strong>of</strong> the endemic species was done by Dixit & Bal Krishna (1990). Manickam &<br />

Irudayaraj (1992) in the Pteridophytic Flora <strong>of</strong> the Western Ghats enumerated 16 endemics from South <strong>India</strong>, whereas<br />

17 endemic species were reported from South <strong>India</strong> by Nayar & Geevarghese (1988, 1993). Subsequently Ch<strong>and</strong>ra<br />

(1998) catalogued a total <strong>of</strong> 234 endemic Pteridophytes from <strong>India</strong> removing 25 species from the earlier lists <strong>and</strong><br />

adding 14 new taxa. A more significant <strong>and</strong> valuable contribution has been made recently by Fraser-Jenkins (2008). He<br />

has removed many <strong>of</strong> the earlier endemic species <strong>of</strong> Pteridophytes as pseudo-endemics which arose mainly due to<br />

mistaken synonyms or the lack <strong>of</strong> underst<strong>and</strong>ing <strong>of</strong> the range <strong>of</strong> species. He has listed only 47 species <strong>of</strong> <strong>India</strong>n<br />

Pteridophytes as endemics. It is observed that there is a vast difference among the observations <strong>of</strong> Pteridologists<br />

regarding the endemic status <strong>of</strong> the <strong>India</strong>n Pteridophytes. One <strong>of</strong> the reasons for this is that the taxonomy <strong>and</strong><br />

nomenclature <strong>of</strong> Pteridophytes is much more confusing than those <strong>of</strong> any other group <strong>of</strong> plants.<br />

This article deals with a brief phytogeographic analysis <strong>of</strong> <strong>India</strong>n Pteridophytes with special reference to the distribution<br />

<strong>of</strong> endemic species in different biogeographic regions <strong>of</strong> <strong>India</strong>.<br />

Distribution<br />

A total <strong>of</strong> 49 species <strong>of</strong> Pteridophytes can be said as endemic to <strong>India</strong>. This includes three allopolyploids which are<br />

neo-endemics <strong>of</strong> fairly recent origin viz., Athyrium kumaonicum, Dryopteris khullari <strong>and</strong> Polystichum polyodon. These<br />

species are distributed in as many as 6 <strong>of</strong> the 10 biogeographic zones <strong>of</strong> <strong>India</strong> (Table 1). Eight species found in the<br />

<strong>India</strong>n Himalayan region are endemic, while 7 species <strong>of</strong> endemic Pteridophytes are reported from North-East <strong>India</strong>.<br />

Among these, four species are common between the Himalayan <strong>and</strong> North-Eastern zones. The highest number <strong>of</strong><br />

endemic Pteridophytes (33) is reported from peninsular <strong>India</strong> (Deccan Peninsula <strong>and</strong> Western Ghats). The only<br />

229


Envis Bulletin<br />

230<br />

<strong>Special</strong> <strong>Habitats</strong> <strong>and</strong> <strong>Threatened</strong> <strong>Plants</strong> <strong>of</strong> <strong>India</strong><br />

species reported as endemic in Semi-Arid zone is also found in Deccan Peninsular region. Five species <strong>of</strong> Pteridophytes<br />

are localized in the Andaman <strong>and</strong> Nicobar Isl<strong>and</strong>s. Other biogeographic zones viz., Trans-Himalaya, Desert, <strong>and</strong><br />

Coasts harbour no endemic Pteridophytes.<br />

Threat status<br />

The Pteridophytes appear to face relatively less threat as compared to the angiosperms. The reasons for this may be<br />

the efficiency with which their spores are dispersed <strong>and</strong> the deep forested habitats they occupy making them less<br />

vulnerable. Moreover, fewer Pteridophytes are exploited commercially for herbal industries <strong>and</strong> as non-timber forest<br />

products (NTFPs). However, widespread environmental degradation restrains them to grow even in their safe haven.<br />

The Pteridophytes with creeping rhizome colonize a habitat more efficiently as compared to the species with erect<br />

rhizome. This explains why polyploid species are more successful compared to the diploids as the former are with<br />

creeping rhizome unlike the later. Likewise, epiphytic species require specific hosts <strong>and</strong> are therefore more vulnerable<br />

to population decline. Unfortunately, the conservation status <strong>of</strong> <strong>India</strong>n Pteridophytes has not been assessed as yet in<br />

view <strong>of</strong> all the biological <strong>and</strong> ecological factors <strong>and</strong> CAMP workshop is still awaited as per the latest IUCN criteria.<br />

However, eleven <strong>of</strong> the endemic Pteridophytes fall into one or the other categories <strong>of</strong> threatened plants (Extinct,<br />

Vulnerable, Endangered <strong>and</strong> Rare) as per 1997 IUCN Red List (Walter & Gillet 1998). Besides, literature survey <strong>and</strong><br />

authors’ personal observations reveal that populations <strong>of</strong> 13 species have been reduced to a critical level <strong>and</strong> they are<br />

at a very high risk. Slight disturbance in their habitat can lead to their total extinction. Eight species are thought to be<br />

‘very rare’ <strong>and</strong> are likely to be in peril if immediate steps are not taken to stop the destruction <strong>of</strong> their habitats.<br />

Concluding Remarks<br />

A comprehensive analysis is still required to be undertaken to re-evaluate the taxonomy <strong>and</strong> status <strong>of</strong> endemic<br />

Pteridophytes. Methodologies for the same are not yet very explicit, each researcher trying to evolve his or her own view<br />

about these species. The number <strong>of</strong> endemic species is likely to increase or decrease following further nomenclature<br />

revision <strong>of</strong> some <strong>of</strong> the species. The populations <strong>of</strong> these species also need to be regularly observed. This is crucial for<br />

the successful underst<strong>and</strong>ing <strong>of</strong> their conservation status. Nevertheless these key species are <strong>of</strong> particular concern<br />

requiring adequate efforts for both their in situ <strong>and</strong> ex situ conservation. Presently, several in situ conservation measures<br />

have been adopted for the angiosperms, however, Pteridophytes have not or only been partially given importance in this<br />

context. Furthermore, it has been found that in most <strong>of</strong> the <strong>India</strong>n ferneries only ornamental ferns are grown <strong>and</strong> not the<br />

endemic or threatened species. Consequently, ex situ conservation <strong>of</strong> these species also needs to be reinforced<br />

through in vitro culture techniques.<br />
