PREFACE 

There are probably 10,000 – 20,000 plant species in Kalimantan. The flora is rich in 

diversity and economically essential, yet has not been fully explored. New species are 

continually being found. New initiatives are needed to promote more exploration, and to 

use this information for practical needs like sustainable forest management and protection 

of Indonesia’s rich biodiversity heritage. 

Collecting plant data requires collection and cataloguing of plant specimens in a herbarium 

– a botanical “library”. Indonesia’s national herbarium is in Bogor. East Kalimantan has a 

regional tree herbarium in Wanariset, Samboja. 

The Berau Forest Management Project (BFMP) identified a need to develop herbarium 

facilities for Berau to better understand its working environment, and to enhance available 

resources for research and education. Berau’s forest is assumed to be biologically rich, yet 

because there has been so little botanical collection in this part of East Kalimantan there is a 

lack of information and references about what trees really are present. Direct benefits 

include a better understanding of forest that will foster ever more appropriate sustainable 

forest management techniques. 

The Berau herbarium has now reached an international standard and offers an excellent 

opportunity to national and international scientists, students and laymen to learn more about 

the plant diversity of East Kalimantan. An advantage of the Berau location is that dry 

herbarium material can be studied with full access to the tropical lowland forest within less 

than two hours drive. It is also part of a commercial concession with practical forest 

operators managing the resource. This makes it an ideal base for many activities like tree 

recognition courses to support sustainable forest management, marketing studies, and also 

for ecological and taxonomic studies.

INTRODUCTION 

Borneo covers about 740000 km 2 and is divided between three countries. To the north lie 

Brunei and the Malaysian states of Sabah and Sarawak. To the south lies the largest part of 

the island, Kalimantan. 

Borneo is one of the most important centres of plant diversity in the world. There are at 

least 10000 - 12000 species of flowering plants and somewhere between 40 - 50% are 

endemic to the island. Scientific studies of Kalimantan’s flora can be dated back to 1822 in 

West Kalimantan, Kutai and the Mahakam River. However, more intensive botanical 

studies were conducted in the northern parts of Borneo, supported by the British 

administration and private companies. British, Dutch and German scientists dominated the 

early 20th century collectors. After 1914, the Northern Borneo Forestry Department started 

to set standards for forest management that included systematic botanical investigations. 

The fruits of these studies include today’s modern botanical collections in Bogor, 

Singapore, Kuching, Sandakan, and more recently in Wanariset, Samboja in East 

Kalimantan. 

Kalimantan’s flora still needs to be better explored. Of Borneo’s endemic species, about 

80% are known from the Malaysian states of Sabah and Sarawak. With more study over on 

the Indonesian side of the border, there is little doubt than many more will be discovered. 

In a long-term collaboration with various research organisations the Forest Research 

Institute Malaysia (FRIM) developed the Tree Flora of Sarawak and Sabah. This is the 

most recent coverage of tree species and their taxonomic status occurring in the Malaysian 

part of Borneo. There is nothing similar for Kalimantan. Yet national and international 

recognition of the economic and conservation value of it forests calls for this gap to be 

filled. There is a need for a concise Identification Flora of Borneo. It would underpin efforts 

to more accurately attempt to conserve and plan sustainable forest management and use of 

this species-rich landscape. This is an immediate and crucial need for more botanical 

exploration and collection in Kalimantan, the institutional, scientific and financial resources 

to support it. 

BACKGROUND 

Botanical surveys in Berau started with the STREK Project at the Labanan concession of PT 

Inhutani 1, in 1989. The overall goal was to develop silvicultural techniques for 

regenerating logged over rain forest as a joint venture between PT Inhutani I, FORDA and 

CIRAD-Forêt. Twelve permanent sample plots (PSP) were established in the richest 

primary, undisturbed forest of the concession. Six more were placed in logged forest. These 

4 ha plots represented the core collection area for tree species collection and study. 

All trees with a dbh >10 cm in each PSP were labelled and identified to species where 

possible. An average of 493 trees ha -1 , representing a range of 370 - 600 was recorded of 

which 65% were identified. Identifications were mainly to species level, using a mixture of 

scientific and vernacular names. During 1992 – 1995, a herbarium collection of mainly 

1

sterile material was set up. Its 3000 samples included 45 families, 129 genera and 579 taxa. 

A database was developed containing the name of each specimen plus some information on 

topics like family, local names, species grouping related to commercial use and volume 

equations. 

In its early phase in 1996 the Berau Forest Management Project (BFMP), within its research 

and development programme, identified a need to improve herbarium facilities. A review of 

the collection showed that collected material did not meet national or international 

herbarium standards in terms of specimen collection, identification, preparation, 

conservation and storage. These needed to improved alongside field data and identification, 

herbarium management and capacity development of field staff. 

Over time and with considerable effort, species identification led to 99% of the tree species 

being accurately identified from the STREK PSP. Training and capacity development was 

an integral part of this process. Herbarium collections were expanded to cover the entire 

Labanan concession, an area of 100000 ha. 

These investments in herbarium facilities and management training consolidated the Berau 

Herbarium as a functioning institution. It provides a sound applied research that meets 

national and international herbarium standards. 

PURPOSE 

There is no reason to suspect that Berau does not truly represent the rich tree diversity 

characteristic of Borneo. Yet because there has been so little botanical collection in this part 

of East Kalimantan – only one scientific collection from the late 1960’s is documented – 

there is a lack of information and references about what trees really are present. This gap in 

knowledge needs to be filled to better understand ecological relationships. In turn, this 

understanding will foster ever more appropriate sustainable forest management techniques. 

This is especially important because the group of species that are harvested commercially is 

going to expand. Forest managers need sound data to ensure that newly harvested forest 

resources are extracted sustainably. Furthermore, like many progressive concessions, 

Labanan is trying to become FSC and LEI certified. The environmental components of both 

systems will require the concession to increase its knowledge of timber species, and use that 

knowledge appropriately. 

In moving forward, BFMP has built upon the STREK accomplishments to further develop 

the herbarium reference collection for Berau, covering the entire Labanan concession. This 

will be met, in large part, by training local staff in species identification, herbarium 

management and use. These are important steps in building up locally available technical 

expertise on tree species, and develop products that meet international botanical standards. 

This report has two purposes. The first is to give an overview of the tree diversity in Berau, 

focusing particularly on the family Dipterocarpaceae, which is of tremendous commercial 

importance as it contains all kapur, keruing and meranti, among others. 

2

The second purpose is to introduce Berau Herbarium. It describes techniques for collection 

and highlights the facilities available to botanists, foresters and others for improving their 

botanical knowledge through self-study and training courses. If the specimens are well 

collected and prepared, with accompanying quality data herbaria, Berau Herbarium can join 

and share its material with the international community. From there specialists can assist 

with difficult identifications and develop longer-term research partnerships. Ultimately, it is 

hoped this will inspire interest in further research in northeastern part of Kalimantan.

Importance value index 

The importance of Borneo as a 

world centre of plant diversity is 

reflected in STREK plot results 

from the tropical lowland 

rainforest of Berau. There is an 

average of 531 trees per ha (dbh 

>10 cm) representing 154 species. 

With a tree species identification 

rate of 99%, mostly to the species 

level 55 families have been found 

present in 48 ha, 12 plots of 4 ha 

each. The most important 

commercial family is the 

Dipterocarpaceae. The most 

important non-commercial family 

is the Euphorbiaceae. Their

Although the standard deviations are 

rather high, indicating high variability 

within the sampled plots, the low 

standard errors demonstrate they are 

representative of overall findings, due 

to the high number of replications, n

LOCATION AND FACILITIES 

The Berau herbarium is integrated into the BFMP Training Centre in Tanjung Redeb, East 

Kalimantan (Latitude 2º 08' N, Longitude 117º 29' E), within the PT. Inhutani I, Adm. 

Berau, complex (figure 4). This is less than an hour’s drive from the Labanan concession. 

The northern and eastern boundaries of the Labanan research areas are demarcated by 

rivers, which provide access by boat. Field camps within the concession provide 

accommodation for 

Figure 4: Location of Tanjung Redeb with the concession Labanan, PT. Inhutani 1, Adm. Berau 

research staff. 

The general herbarium 

room, in the training 

centre (figure 5) 

currently contains 168 

boxes of herbarium 

material, a deep 

freezing unit for

and various working 

and office facilities. 

Attached is an external 

drying room with a 

special electric oven 

for gentle drying of 

fresh plant material. 

Other training centre facilities, such as teaching, presentation and computer capacities, are 

made available for herbarium activities, as are field camps (figure 6). The building is fully 

air-conditioned.

ORGANISATION AND MANAGEMENT 

The Berau Herbarium is as an extension of Herbarium Wanariset in Samboja (WAN), 

which is registered in the international catalogue of the herbaria of the world, Index 

Herbariorum. For the specimen collection it has its own series code “BERAU”. This 

follows international herbarium standards and the collection is thus linked to the National 

Herbarium of The Netherlands, Leiden branch (L). The Berau Herbarium therefore connects 

to other herbaria with significant Asian collections, particularly A, BO, E and K via 

Wanariset and Leiden. 

PT. Inhutani I and BPK Samarinda jointly manage the herbarium. Two trained staff 

members from each organisation are permanently involved and responsible for professional 

management activities including material collection, preparation, labelling, storage, file 

update and other general operations. BFMP, Wanariset Samboja and the L presently support 

them. 

PLANT MATERIAL COLLECTION AND PREPARATION 

SOME DEFINITIONS 

Herbarium specimen 

A herbarium specimen is a whole plant or plants, or part of a plant of such a size that when 

pressed flat and dried will fit on a sheet of stiff paper or card. The specimens are pressed 

flat and dried. The Berau herbarium uses 26 x 42 cm sheets, the same size adopted by BO 

and WAN. Specimens are selected to show essential features of branches, leaves, flowers, 

and fruits. A number tag relating to a numbered note in a field notebook accompanies each 

specimen. 

Number tag 

A numbered tag connects the specimen to field notes made when the specimen was 

collected. Each number is unique, and is prefixed with the herbarium code – in this case, 

“B”. Pencil should be used to write on tags, as ink is generally not permanent, washing off 

when coming in contact with water, alcohol or sap. 

Field notebook 

A field notebook records data including: 

 

 

 

 

The collector and collection number 

Place of collection 

Date of collection 

Features of the plant that will not be available on specimens 

6

Family 

Genus 

Species 

Vernacular name with the name of the dialect or language 

Local uses 

Collector Prefix 

Number 

Location (Country/ Province/ Administrative region/ Town/village 

Longitude and latitude 

Altitude 

Habitat 

Habit – this includes include notes on overall form of the plants, height, diameter, 

bark, buttresses, wood, colour of flowers and fruits; essentially those characters that 

will be not be available on specimens 

Like number tags, pencil should be used for writing in field books, as it will not wash off. 

Selecting the specimens 

When plants are small and fit to the size of the mounting paper one should dig out the whole 

plant and dry the specimens including a portion of the root system. When plants are woody 

or too large to make an entire specimen, usually only fertile clippings will be taken. Fertile 

clippings are branches with flowers or fruits (preferably both). Generally, at least seven 

duplicates are collected. Number tags are attached and the material stored temporarily in 

large polythene bags to avoid the specimens drying out before they can be properly 

processed. 

Large trees should be climbed to reach the fertile branches (figure 7). Safety regulations 

must be followed. At minimum, two trained climbers should be involved in the collecting 

activities. 

7

Numbering of collections 

To make record keeping easy, each specimen, or group of duplicates of a specimen, are 

given a unique number. The simplest and most recommended method is recording the 

Collector’s surname, followed by one or more digits (prefix) and the consecutive number 

Figure 7: High tree climbing with harness for collection of fertile 

specimens 

starting with 1. An example is “Sidiyasa 

Berau 1”. 

In summary: 

 

 

 

Each collection receives its own 

unique number 

Each duplicate of the same 

individual gets the same number 

Different individuals of the same 

species get a different number 

If a numbered specimen is lost, damaged or destroyed, do not re-use its number. It should 

be shown as cancelled in the field book as well as in the database. If a mistake is made and 

a number duplicated, or two different plants are collected under the same number, separate 

the collections by using letters as suffixes to the original number, such as “Sidiyasa Berau 

1A”. 

Basic equipment 

Recommended, basic, equipment for a 

plant collector includes the following:

Rucksack. 

Secateurs 

Pocket knife 

Machete 

GPS 

Altimeter 

Binocular 

Camera and films 

Polythene bags of different sizes, rice sacks 

Jerry can with methylated alcohol (spiritus 80%)

Field books, pencils, paper, number tags (tie-on watchmakers tags), newspaper, 

plastic string 

Climbing equipment including harness (figure 8), climbing ropes of different length, 

shoes with spikes, leather gloves 

PRESERVATION OF SPECIMENS 

Figure 9: Preparation of fresh material packing 

Damaged material is worthless to a herbarium. 

Fresh plant specimens will quickly rot or be 

damaged by mildew unless preservative treatment is 

given. Preservation techniques include drying and 

chemical treatments. 

Chemical treatment (Wet or Schweinfurth method) 

Drying specimens in the field is time consuming and 

the result often unpredictable. It is better to preserve 

plant specimens in the field using methylated alcohol 

(spiritus) at an 80% concentration. Whereas the 

disadvantage of wet preservation is that the liquids 

are bulky and heavy to carry, the material can be 

kept in sealed plastic bags for as long as nine 

months. To achieve this the spiritus should not drop below a concentration of 70%. 

Each specimen, with its number tag, is 

placed between newspaper sheets (figure 9). 

Any plant parts sticking out from the 

newspaper are clipped to stop them later 

puncturing plastic bags (figure 10). 

Figure 10: Trimming of plant samples to newspaper size 

When enough sheets have been accumulated 

make a convenient-sized bundle, the bundle 

is compressed and tied (figure 11). 

Bulky and spiny material is best placed in 

the centre of the bundle. 

The bundle is then put into a heavy polythene bag. About half a litre of 80% spirituous is 

added per 10 cm of bundle height (figure 12). When full, the open end of the bag is folded 

and sealed. The alcohol fills the bags as vapour, and preserves the contents. These bags 

should be packed into a suitable strong sack for extra protection. Rice sacks are fine for this. 

The final package is very robust and is strong enough to be carried and posted.

Figure 11: Tying a bundle of specimens 

Back in the herbarium the material will 

be dried when convenient. 

Drying 

Proper drying and chemical treatment 

preserves specimens by preventing 

bacterial and fungal decay. Removal of 

water from the plant tissues still allows 

specimen morphological features to be 

studied. 

Figure 12: Adding spiritus for preservation 

Figure 13: Electrical drying stove 

Modern drying methods use an electrical drying stove, available at the Training Centre in 

Berau. Specimens are dried directly with heated air while a weight flattens them (figure 13). 

Depending on the thickness of branches and fruits the process takes about two or three days. 

10

FUNCTION AND ORGANIZATION OF A HERBARIUM 

Collecting plant specimens accumulates dried collection. In due course the specimens are 

identified and arranged so that specimens of the same species are located together, and that 

related species are close to each other. There are various internationally accepted ways to 

arrange specimens, as there are of arranging books in a library. 

ESSENTIAL REQUIREMENTS FOR A HERBARIUM BUILDING 

 

 

 

 

 

 

 

 

Location – avoid sites where there is a risk of flooding, spreading fires, or landslides 

Construction – fireproof, with smoke or heat detection alarm system 

A cool, dry atmosphere with humidity as low as possible, 24 hours air condition or 

de-humidification 

Adequate work space on benches and tables 

Good ventilation – windows should be screened to avoid access by insects 

Excellent light 

Separate room for drying purposes 

Separate room for preparation and mounting activities 

DRYING SPECIMENS 

Checklist of materials: 

 

 

 

 

 

 

Newspaper 

Corrugated cardboard, half the size of broadsheet newspapers 

Secateurs 

Tags 

Foam cut into the same size as cardboard 

Electric drying stove 

Place the fresh or treated, trimmed and tagged specimens between fresh newspaper sheets. 

Make sure that the specimen will show upper and lower surface of leaves when dry. If the 

leaves are too large to fit into the folder, they should be folded. In compound leaves one 

leaflet of a pair can be trimmed in order to reduce its size for the space available. 

11

This newspaper folder is put on corrugated 

cardboard (figure 14). In the case of thick and 

fleshy fruits or flowers, a piece of foam the 

same size as cardboard, with relatively big 

holes, should be put on top of the folder. This 

keeps the leaves flat and the cardboard level. 

The specimen can than be put directly in the 

drying stove. This procedure should be repeated 

until the drying stove is full. A wooden board 

should then be put on top of the pile with a 

heavy weight like a stone on top. This will keep 

the specimens flat during the drying and 

shrinking processes, as the pressure always 

remains the same. Temperature should be kept 

70°C to avoid overheating and burning of the 

paper as well as the material. 

Figure 14:Layers of foam and cardboard keep leaves flat 

during drying 

All specimens should be dry within 36 – 48 

hours, however, after 24 hours material should 

be checked for specimens that are already dry 

(figure 15). These should be removed. If the 

drying process takes too long the material can 

become brittle. 

PROCESSING UNMOUNTED SPECIMENS 

As a rule usually 7 – 9 duplicates of each tree 

will be collected. At least one set remains in 

Berau, the other duplicates should be sent to the 

Wanariset herbarium to be distributed later to 

other herbaria (L, BO, BZF, K, A, SAN, etc.). 

When sorting duplicates, the following points 

should always be considered: 

 

 

 

If the flowers are unisexual, both male 

and female flowers should be 

represented in each duplicate. 

As far as possible make sure that each 

duplicate has a complete range of stages 

– flower buds, flowers, young fruits, 

mature fruits 

Each duplicate should have a label 

attached together with an “Ex HERB” 

slip or a cancellation stamp 

Figure 15: Unpacked, dry fertile specimen with number tag 

12

Each duplicate is placed in a double newspaper; if the material is bulky, place a second 

newspaper the opposite way round. The duplicates can then be distributed to other herbaria. 


MOUNTING SPECIMENS 

 

 

 

 

 

 

Acid free cartridge paper 

Paper capsules 

Scissors 

Acid free paper straps 

Cardboard supporters 

Accession number stamp 

When properly prepared and well cared for, mounted herbarium specimens should last 

indefinitely. It is therefore very important to select mounting paper, adhesives and inks that 

are of archival quality. 

The two main aims of the mounting process are: 

 

 

To display the specimens and data to allow maximum exposure of features 

To preserve the specimen by securely attaching it to strong mounting paper, but at 

the same time allowing for the removal of small portions for more detailed study 

IDENTIFICATION OF SPECIMENS 


 

 

 

 

Binocular microscope (50x) 

Lamp 

Needles, forceps, preparation materials 

Identification materials (Books: Floras, Journals etc; CD) 

Before filing, specimens should be checked and the correct identity should be ascertained, 

using identification keys in books or CD’s. With the help of the current collection one 

should also compare the material with existing material of the same species to further check 

if the correct scientific name has been applied. 

13

ARRANGEMENT 

Figure 16: Cutting mounting straps 

Choose the best way of presenting the 

specimen in order to display all its characters 

as far as possible. Labels should be on the 

bottom right hand corner, just 0.5 cm from 

the lower margin. The consecutive accession 

number stamp should be in the top right hand 

corner, just 0.5 cm below the upper margin. 

Paper capsules should be on the top left hand 

corner, just 0.5 cm below the upper margin. 

Number tags must be preserved with the 

specimens by gluing them to the sheet still attached to the specimen. 

STRAPPING METHOD 

Small straps of gummed linen (figure 16) or 

paper are placed across the specimen at 

intervals and stuck to the sheet at either end. 

Thin straps should be used on finer portions 

of the specimen and thicker straps where extra 

strength is needed, like over stems or thick 

fruits. Avoid strapping over important details, 

such as flowers or small inflorescences, as 

well as the nodes on a twig. When strapping is 

applied across a leaf-blade, only attach the 

ends of the strap where contact is made with 

the paper. This allows the leaf to move freely 

when the sheet is handled.

straps

sheet. A Genus cover covers groups of 

species covers. Genus covers are normally 

the more robust and are provided with a 

family and genus name in the bottom right 

hand corner. Often different colours are used 

to indicate geographical areas. For example, 

in WAN different colours are used for the 

four provinces of Kalimantan and areas 

outside Kalimantan. Type material is 

protected using red genus covers.

Arrangement of Herbarium Collections 

The herbarium is a storehouse of valuable information, like a library. And like a library, it 

must be arranged in such a way that information can easily be retrieved. 

The Berau herbarium uses an alphabetical arrangement for families as well as for genera 

and species. This makes it easy for non-specialists to find specimens, and unskilled 

personnel can add mounted material to the herbarium. 

Wooden boxes in cupboard pigeonholes are used to store specimens. Filing of specimens 

starts at the top left hand corner (A) and moves down that column then moving to the top of 

the second column of pigeonholes. The bottom left hand corner therefore contains 

specimens starting with Z. 

Figure 19: Rack with boxes for permanent storage of herbarium specimens 

Outside, the contents 

are labelled, for 

example: 

-Annonaceae 

-Orophea 

-hexandra 

The species marking 

is the alphabetically 

lowest species in the 

box. 

Pests and treatments 

Long-term preservation of herbarium specimens must involve constant vigilance to protect 

them from damage by pests. Under humid tropical conditions insects and fungi pose two 

serious threats. 

Those insects most commonly found and the most destructive are: 

 

 

 

 

Herbarium beetles 

Cigarette, or tobacco beetles 

Silverfish, or fish moths 

Cockroaches 

15

Termites and ants 

Apart from insects and fungi like moulds and mildew, only mites, mice and rats are of 

significant importance. 

Detection 

Regular visual inspection is needed to detect the evidence of damage. The best place to 

check are families like Apiaceae, Asteraceae, Lamiaceae, Ericaceae and other plants which 

contain latex, as insect pests are known to be naturally attracted to them. 

Prevention 

Minimise insect access to the building. Fit fine screens on entry points to the building. 

Close doors and windows carefully. Avoid bringing living material and food to the storage 

room. 

Fumigation of herbarium rooms and cabinets and poisoning specimens is believed to be 

valuable in many herbaria in providing relatively long-term protection against insect attack. 

However, the chemicals used are usually very poisonous to people and so are not 

recommended here. 

Figure 20: Deep freezer for 

decontamination of specimens from 

insects 

The Berau herbarium instead decontaminates specimens 

using deep-freezing (figure 20), a safe and reliable 

alternative. This method has been used very successfully in 

the last decade in Wanariset in combination with a fully air 

conditioned room. 

The freezer unit should be a standard, branded name, topopening 

domestic chest freezer. The temperature should go 

below –18 o C. Make sure that at least 6 boxes can be 

packed to give maximum space economy. 

Specimens should be frozen, sealed in the freezer, for a 72- 

hour total period. 

The freezer should be maintained. Ice build-up in the 

tropics is usually high, so it is recommended to defrost the 

freezer at relatively short intervals, especially if it is run 

under particularly high moisture conditions. 

Once a month the herbarium storage room should be sprayed with a commercial insecticide 

to repel ants and other insects outside the racks and boxes as these can cause considerable 

damage. 

16

DATA PROCESSING 

Data processing is performed with the database “BRAHMS” (Botanical Research and 

Herbarium Management System), which supports three overlapping categories of project: 

 

 

 

Management and curation of herbarium collections 

Production of taxonomically oriented outputs 

Production of geographically oriented outputs 

In the Berau Herbarium the first and the third category will mainly be used for the 

production of labels, determination slips and lists, geographic checklists, and biodiversity 

survey results. 

The key advantage provided by a database such as BRAHMS is improved access to data. 

For example, as well as assembling data by species, they can be assembled and ordered by 

collector name, geographical area, ecological area, altitude range, determination status, 

species group. 

Figure 21: Data processing of specimen information 

RAPID DATA ENTRY (RDE) 

Field data are first entered into 

spreadsheet like files external to and 

independent from BRAHMS. RDE files 

can be optimised for any particular task 

(figure 21). In Berau we select the 

fields, which are used either in 

Wanariset (WAN) or in Leiden (L) to 

make exchange of data as easy as 

possible. 

Rapid Data Entry is easy to learn, 

flexible and allows data entry to proceed 

on multiple workstations without access to a network. RDE provides an extra layer of 

database security as RDE data files are easily checked and importing can be centrally 

controlled. 

DATA EXTRACTION 

Data queries – leading to the generation of outputs – are initiated by selecting the “Extract” 

data option on the main BRAHMS menu. 

OUTPUT 

Data in extract files can be processed and formatted directly by BRAHMS or passed to 

other spreadsheets or databases such as Excel. 

17

Labels, determination slips and other categories of formatted “collection summaries” can be 

created directly from BRAHMS. 

The BRAHMS Report Generator (BRG) includes default report templates for commonly 

used lists and indexes, sample checklists formats, and more complex monograph formats for 

specific journal and monograph series. 

EXPORTING DATA TO OTHER FORMATS 

Any subset of data from the main database can be exported from BRAHMS. Broadly, data 

may be exported in the following ways: 

 

 

 

 

RDE format – data exported into RDE files can be auto-transferred to other 

BRAHMS systems. RDE files (xBase tables) have a highly segregated data structure 

and are easily processed by other packages 

Spreadsheet/database formats – delimited formats including Access, Excel, Lotus, 

FoxPro, Paradox 

Text files 

Specialised packages – data can be exported to range of specialised systems. 

Examples are TREMA, ArcView, MapInfo and ALICE.

ACHIEVEMENTS OF THE BERAU HERBARIUM 

Within the framework of the BFMP project more than 1700 specimens have been collected 

during several training courses in the Labanan concession area. About 1200 are available as 

duplicates in the Berau herbarium, of which about 1000 specimens have been mounted and 

covered with specimen, species and/or genus covers. The rest of the specimens, the early 

collections made when it was not certain if Berau would have a Herbarium, are housed at 

the Wanariset herbarium. Other duplicates are available in Bogor, Leiden, Kew, Arnold 

Arboretum, Kuching and Sandakan. All specimens have been filed alphabetically and every 

box has been provided with a label on the outside that indicates its content. 

Almost 100 boxes are now filled. Almost 500 index cards have been typed for a quick 

search on specimens. More than 1500 specimen covers have been cut and glued and about 

750 species/genus covers have been made. Every cover has been marked with the correct 

scientific name. 

TRAINING 

Following TPTI regulations, in the forest inventory the identification of tree species for 

harvesting, protection, replanting and marketing makes use of local names and timber trade 

names given by local staff. This species identification practice is far from being uniform 

and correct; it depends largely on the origin and experience of local people. Translation of 

vernacular names to scientific names is usually impossible. 

Training in species identification of local inventory staff members, using scientific names 

was thus an early task of BFMP. Several training sessions in species identification, material 

collection including tree climbing with climbing equipment, material preparation, 

herbarium management and use were conducted. Trainees were selected from inventory and 

research staff of PT. Inhutani I as well as from BPK Samarinda. 

The following training in tree species identification and herbarium management were 

conducted:

Future training activities should concentrate on field collections in the region, such as 

Tanjung Redeb, Tanjung Selor and Tarakan and on material preparation and identification 

in Berau, using the training and herbarium facilities. Trainees should come from PT. 

Inhutani 1 and other concession of the region. BPKS and probably BLK Samarinda could 

provide competent trainers. Also, technical staffs of PT. Inhutani 1 are now capable of 

giving training in botanical fieldwork, herbarium techniques and management. These 

activities will further stimulate growth of the Berau herbarium. 

FUTURE HERBARIUM USE AND EXPANSION 

The Berau herbarium has now reached an international standard and offers an excellent 

opportunity to national and international scientists, students and laymen to learn more about 

the plant diversity of East Kalimantan. An advantage is that dry herbarium material can be 

studied with full access to tropical lowland forest within a few hours drive. This makes it an 

ideal base for many activities like tree recognition courses, ecological and taxonomic 

studies. 

So far the collections are mainly from the Labanan concession within the PT Inhutani I 

Berau concession, yet could be easily expanded to neighbouring areas like Sembarang, 

Malinau, Tarakan, and Bulungan. This will require regular field trips to certain areas, best 

conducted with a training component for local cruisers or tree spotters. This will ensure a 

high level of collections coming into the herbarium and as duplicates going out to 

internationally recognized herbaria, for the benefit of all.
