INTROD<strong>UC</strong>TION<br />
This report describes the methods and results of a preliminary special-status plant survey per<strong>for</strong>med <strong>for</strong> the<br />
Bureau of Land Management (BLM) in the <strong>Cache</strong> <strong>Creek</strong> Wilderness (hereafter referred to as “the Wilderness”).<br />
The 27,296 acre Wilderness is adjacent to the confluence of the north and south <strong>for</strong>ks of <strong>Cache</strong> <strong>Creek</strong> within the<br />
upper <strong>Cache</strong> <strong>Creek</strong> watershed, south of State Highway 20, west of the BLM Bear <strong>Creek</strong> Ranch, east of Morgan<br />
Valley Road, and north of the Rieff-Rayhouse Road, in Lake County, Cali<strong>for</strong>nia (Fig. 1). The Wilderness is<br />
adjacent to a patchwork of state, federal, and private rural and natural lands. Walker Ridge and Bear Valley are<br />
present north and northeast of the Wilderness. The University of Cali<strong>for</strong>nia McLaughlin Reserve is located to the<br />
south. Together, the Wilderness and the BLM Bear <strong>Creek</strong> Ranch <strong>for</strong>m the <strong>Cache</strong> <strong>Creek</strong> <strong>Natural</strong> <strong>Area</strong>.<br />
The primary purpose of this survey was to identify and map occurrences of special-status plants within the<br />
Wilderness. In summary, eight Cali<strong>for</strong>nia Rare <strong>Plant</strong> Rank list 1B special-status plants were encountered during<br />
the field survey: adobe lily (Fritillaria pluriflora), Snow Mountain buckwheat (Eriogonum nervulosum), drymary<br />
dwarf-flax (Hesperolinon drymarioides), Hall’s madia (Harmonia hallii), Socrates mine jewelflower<br />
(Streptanthus brachiatus), Colusa tidy-tips (Layia septentrionalis), Jepson’s milkvetch (Astragalus rattanii var.<br />
jepsonianus), and round-leaf stork’s bill (Cali<strong>for</strong>nia macrophyllum). In addition, six Cali<strong>for</strong>nia Rare <strong>Plant</strong> Rank<br />
list 4 special-status plants were encountered: Cleveland’s ragwort (Packera clevelandii), serpentine collomia<br />
(Collomia diversifolia), serpentine milkweed (Asclepias solanoana), bare monkey flower (Mimulus nudatus),<br />
swamp larkspur (Delphinium uliginosum), and Cleveland’s milkvetch (Astragalus clevelandii).<br />
PRE-FIELD INVESTIGATION<br />
METHODS<br />
Be<strong>for</strong>e conducting the survey, a list of special-status plants with potential to occur in the Wilderness was<br />
compiled by per<strong>for</strong>ming database searches of the Cali<strong>for</strong>nia Native <strong>Plant</strong> Society’s (CNPS’) Electronic Inventory<br />
of Rare and Endangered Vascular <strong>Plant</strong>s of Cali<strong>for</strong>nia (CNPS 2010) and the Cali<strong>for</strong>nia Department of Fish and<br />
Game (DFG) Cali<strong>for</strong>nia <strong>Natural</strong> <strong>Diversity</strong> Database (CNDDB 2010). The database searches included the<br />
Benmore Canyon, Wilbur Springs, Salt Canyon, Lower Lake, Wilson Valley, Glascock Mtn., Middletown,<br />
Jericho Valley, and Knoxville U.S. Geological Survey (USGS) 7.5 minute quadrangles. A survey package was<br />
prepared, including photographs of and habitat summaries <strong>for</strong> all special-status plants likely to be encountered.<br />
The survey packets were used to familiarize our field botanists with the characteristics and blooming periods of<br />
special-status plants with potential to occur at the Wilderness.<br />

Special-Status <strong>Plant</strong>s Survey 2 December, 2010
The special-status plant habitat summaries indicated that many of the special-status plants with potential to occur<br />
at the Wilderness grow on serpentine soils. There<strong>for</strong>e, we searched aerial photographs and Google Earth images<br />
of the Wilderness <strong>for</strong> the blue signature of serpentine soils. Based on this in<strong>for</strong>mation gathered from aerial<br />
images, as well as previous knowledge of where certain special-status plants are likely to occur, we decided to<br />
target the following areas of the Wilderness <strong>for</strong> visits: 1) the eastern edge of the Wilderness where heavy adobe<br />
clay soils are present; 2) serpentine soil areas surrounding the Rocky <strong>Creek</strong> drainage; and 3) serpentine soil areas<br />
at the southern boundary of the Wilderness at the terminus of the eastern <strong>for</strong>ks of Rocky <strong>Creek</strong> Road (the area<br />
known as Brushy Sky High on some maps). We confirmed our choices by examining soils maps and discussing<br />
the geology of the area with soils experts.<br />
Access to targeted areas in the Wilderness was challenging, because of the need to cross <strong>Cache</strong> <strong>Creek</strong> or private<br />
lands. A preliminary visit to the southern boundary of the Wilderness was made on November 17, 2009 with<br />
Pardee Bardwell of BLM, and we obtained names and phone numbers <strong>for</strong> several land owners in that area. We<br />
then contacted the Lake County Assessor’s Office to obtain the addresses of key land owners on the southern<br />
border of the Wilderness; we wrote letters to the land owners and provided them with our contact in<strong>for</strong>mation. We<br />
were <strong>for</strong>tunate that several land owners granted us permission to use their roads and cross their land. In addition,<br />
Gordon Harrington, a member of our botany team, obtained the contact in<strong>for</strong>mation <strong>for</strong> a land owner on the<br />
northern side of the Wilderness; that land owner allowed us to cross his land, greatly reducing our hiking time on<br />
that side of the Wilderness. The following is a summary of the contacts we made.<br />
Stephen Gilardi, owner of parcels along the eastern <strong>for</strong>k of Rocky <strong>Creek</strong> Road: parcels 5, 6, and 7 in<br />
Section 36, and parcels 49, 50 and 53 in Section 1. The road leading into his residence has a locked gate<br />
that he and a neighbor (Charles Carlisle) control. His residence is often referred to as “Brushy Sky High”<br />
on maps. Address: P.O. Box 1684, Lower Lake, CA 95457. Mr. Gilardi lives in Santa Rosa in the<br />
wintertime. We used Mr. Gilardi’s road to access the Wilderness on the southeastern side twice.<br />
Rick Foltz, owner and resident of parcel near large lake on southern boundary of the Wilderness. His road<br />
is just to the west of Mr. Gilardi’s road. Phone number: 707-994-1584. He has access to an undeveloped<br />
road leading upslope into the Wilderness on the southern side that we never used.<br />
Carol Campbell, owner and resident of parcel near the terminus of the western <strong>for</strong>k of Rocky <strong>Creek</strong> Road<br />
near the headwaters of Rocky <strong>Creek</strong>. The road leading to Ms. Campbell’s house has a locked gate with a<br />
BLM lock on it. Phone number: 707-350-1868. We used Ms. Campbell’s road to access the Rocky <strong>Creek</strong><br />
drainage twice.<br />

Special-Status <strong>Plant</strong>s Survey 3 December, 2010
Nick Buffone, owner of parcels along the north <strong>for</strong>k of <strong>Cache</strong> <strong>Creek</strong> west of the confluence of the north<br />
and south <strong>for</strong>ks, including a well-maintained private road with a locked gate. Mr. Buffone lives in the Bay<br />
<strong>Area</strong>. Work phone number: 510-783-5222. We crossed Mr. Buffone’s property on foot numerous times<br />
but never unlocked the gate.<br />
FIELD SURVEY METHODS<br />
We visited the Wilderness on March 7, April 3 and 24, May 5 and 12, and June 9, 16 and 25, 2010 to per<strong>for</strong>m a<br />
preliminary special-status plant survey. Tracks showing our routes were recorded using a Garmin GPS (Figure 2).<br />
Botanists who participated in the survey included Ellen Dean, Craig Thomsen, Gordon Harrington, Jack<br />
Alderson, Tom Zavortink, Mark Bibbo, Lisa Serafini, John Chau, and Patrick McIntyre. The following areas were<br />
accessed:<br />
March 7: The middle portion of the Rocky <strong>Creek</strong> drainage; we crossed the north <strong>for</strong>k of <strong>Cache</strong> <strong>Creek</strong> twice,<br />
traversed portions of the Redbud Trail, and walked cross-country to Rocky <strong>Creek</strong>.<br />
April 3: Eastern edge of the Wilderness. From the Judge <strong>Davis</strong> Trailhead, we walked south on the Ridge Trail.<br />
April 24: Wilson Valley, the confluence of Rocky and <strong>Cache</strong> <strong>Creek</strong>s, and portions of the lower reaches of Rocky<br />
<strong>Creek</strong>. From the Redbud Trailhead we walked across private and public lands crossing <strong>Cache</strong> <strong>Creek</strong> four times.<br />
May 5: Serpentine areas on the western side of the north <strong>for</strong>k of <strong>Cache</strong> <strong>Creek</strong>. Initially, we were attempting to<br />
resurvey portions of the Wilderness visited in our March 7 hike, but could not cross <strong>Cache</strong> <strong>Creek</strong> (water levels too<br />
high).<br />
May 12: Southern edge of the Wilderness via Steve Gilardi’s property (he accompanied us and showed us trails).<br />
Given the elevation at that end of the Wilderness, it was too early to find most plants in flower, but this visit<br />
prepared us <strong>for</strong> a more fruitful survey on June 25.<br />
June 9: West side of the north <strong>for</strong>k of <strong>Cache</strong> <strong>Creek</strong>. This was another attempt to retrace our March 7 hike, but we<br />
were still unable to cross <strong>Cache</strong> <strong>Creek</strong>, despite data obtained from the Yolo Flood control district.<br />
June 16: Southern edge of the Wilderness via the west <strong>for</strong>ks of Rocky <strong>Creek</strong> Road and gated private road; we<br />
climbed down the Rocky <strong>Creek</strong> drainage from south to north and back.<br />
June 25: Southern edge of the Wilderness via Steve Gilardi’s property. We made a large loop, investigating the<br />
serpentine drainages and slopes northwest of his property.<br />

Special-Status <strong>Plant</strong>s Survey 5 December, 2010
Due to the challenges of needing to hike cross-country quickly in the Wilderness in order to access the areas we<br />
wanted to search, it was difficult to identify and record all plants we passed during our surveys. There<strong>for</strong>e, we<br />
decided to use a recent plant list from the adjacent Bear <strong>Creek</strong> Ranch (Dean et al. 2009) as the basis of a plant list<br />
<strong>for</strong> the Wilderness. Given the proximity, geologic history, and natural communities, it is likely that most of the<br />
plants on the Bear <strong>Creek</strong> Ranch list occur in the Wilderness. We decided to only collect and identify plants that<br />
we believed were new to the list. All plants collected were identified to the highest taxonomic level necessary.<br />
Nomenclature and plant families used in the rare plant table and plant list in Appendices A and B mostly follows<br />
the 1993 edition of the Jepson Manual, Higher <strong>Plant</strong>s of Cali<strong>for</strong>nia (Hickman 1993), however special-status plant<br />
names and some other names were updated to the nomenclature that is being used by the Jepson Flora Project<br />
(available online 2010). Most plants new to the list were pressed, labeled and added to the herbarium at the <strong>UC</strong><br />
<strong>Davis</strong> <strong>Center</strong> <strong>for</strong> <strong>Plant</strong> <strong>Diversity</strong>.<br />
It was difficult to document and classify all vegetation types that we encountered while walking cross country in<br />
the Wilderness. Producing a comprehensive vegetation map was beyond the scope of this project, and no<br />
vegetation plots were sampled. However, photographs and notes were taken in the field to provide a general<br />
description of the Wilderness vegetation. The vegetation of the site was classified using the Manual of Cali<strong>for</strong>nia<br />
Vegetation (Sawyer et al. 2009).<br />
When special-status plants were encountered, their locations were recorded as decimal degrees coordinate points<br />
in the field using a Garmin GPS. With the assistance of James Weigand (BLM), the point files were used to create a<br />
map showing the distribution of special-status plants encountered in the Wilderness.<br />
RESULTS<br />
CHARACTERIZATION OF CLIMATE, GEOLOGIC FEATURES, AND SOIL TYPES<br />
The climate in Lake County is characterized by cool, wet winters and warm, dry summers, with an average annual<br />
temperature (near Clear Lake) of about 56 degrees. The average daily maximum temperature in summer is 91<br />
degrees with an average daily minimum winter temperature of 44 degrees (Lakeport). Average rainfall <strong>for</strong> the<br />
Wilderness region is about 27 inches annually. The first freeze in fall commonly occurs from the middle of<br />
October to the middle of November with the last freeze in spring usually occurring from the last week of April to<br />
the middle of May (Hatfield 1989).<br />
The Wilderness is located at elevations ranging from approximately 850 feet above sea level within the <strong>Cache</strong><br />
<strong>Creek</strong> drainage to more than 2,800 feet near its southern boundary. The geologic features of the Wilderness<br />
include: the <strong>Cache</strong> Formation, <strong>for</strong>ming much of the northern portion, with non-marine Pleistocene lake and<br />
stream bed materials composed of pebbly sandstone, conglomerate, siltstone and tuff, and dating back 10,000 to 6<br />

million years; the Coast Range Ophiolite—ultramafic rock that is partly serpentinized—<strong>for</strong>ming most of the<br />
central portion of the Wilderness, dating back about 150 million years (Jurassic); and the Great Valley Sequence,<br />
covering much of the east and southwest portions, with marine mudstones, siltstones, sandstones and<br />
conglomerates from the late Mesozoic age, 140-165 million years old. The Great Valley Sequence comprises both<br />
the Lower Cretaceous Great Valley Sequence, which <strong>for</strong>ms much of the eastern boundary, and the Lower<br />
Cretaceous-Upper Jurassic Great Valley Sequence, which is interspersed within the Wilderness. Soil types<br />
associated with the geologic features in the Wilderness are numerous. There are five soil complexes/associations<br />
that are part of the <strong>Cache</strong> Formation, 15 that are part of the Great Valley sequence, three associated with the<br />
Coast Range Ophiolite, and two that are recent alluvial deposits (Table 1; NRCS 2010; pers. comm. with Dr. R.<br />
Southard).<br />

Many of the special-status plants that we encountered during the 2010 surveys grow on serpentine soils of the<br />
Henneke-Montara-Rock outcrop complex of the Coast Range Ophiolite. These soils occupy an extensive area in<br />
the southern/central part of the Wilderness, including parts of the Rocky <strong>Creek</strong> drainage and the area known as<br />
Brushy Sky High. The Wilderness’s Henneke-Okiota complex serpentine soils (also Coast Range Ophiolite)<br />
could not be explored this field season but are known to support special-status plants at the adjacent BLM Bear<br />
<strong>Creek</strong> Ranch and elsewhere. The soils of the Phipps complex (<strong>Cache</strong> <strong>Creek</strong> Formation) found on both sides of the<br />
south <strong>for</strong>k of <strong>Cache</strong> <strong>Creek</strong> and the west side of Rocky <strong>Creek</strong>, which are derived from alluvium (including<br />
serpentine-derived alluvium), provide habitat <strong>for</strong> a three special-status plants. Skyhigh-Sleeper-Millsholm soils of<br />

VEGETATION PATTERNS AND ALLIANCES<br />
Statewide (and nationwide), there is an ef<strong>for</strong>t to describe vegetation based on the dominance of a single-species<br />
within a given stand, referred to as “alliances” (Sawyer et al. 2009). As stated previously, a vegetation alliance<br />
map <strong>for</strong> the Wilderness was beyond the scope of this project, and we did not do any vegetation sampling.<br />
Nevertheless, to provide a preliminary description of Wilderness vegetation, we developed a provisional list of 25<br />
published and unpublished alliances that we observed along with their rarity rankings (Table 2). We used the<br />
2009 Manual of Cali<strong>for</strong>nia Vegetation to classify the vegetation we encountered, and we had the following usage<br />
problems: 1) there is no minimum mapping unit provided in the classification; 2) we encountered vegetation<br />
assemblages not described in the classification; 3) we encountered assemblages with no clear dominant.<br />
Photographs of many of these alliances are provided in Appendix C. Descriptions of unpublished alliances follow.<br />

UNPUBLISHED ALLIANCES<br />
Native Unpublished Alliances<br />
Achyrachaena mollis and Micropus cali<strong>for</strong>nicus Provisional Alliances<br />
Among the undescribed alliances that we observed were dense stands of the native annual herbaceous plants blow<br />
wives (Achyrachaena mollis) and slender cottonweed (Micropus cali<strong>for</strong>nicus) on non-serpentine soils. These<br />
assemblages may be “unique stands,” i.e., having never <strong>for</strong>med sufficient number of stands or a broad enough<br />
range to be considered their own alliance (Alexander et al. 2007). It is also possible that these stands are remnant<br />
prairie assemblages that were more prevalent prior to the widespread invasion of non-native plants into prairiegrassland<br />
communities, or perhaps they are only variants of larger prairie-grassland types that have mostly<br />
disappeared. Species associated with the Achyrachaena mollis alliance were farewell-to-spring (Clarkia sp.),<br />
miniature lupine (Lupinus bicolor), chick lupine (L. microcarpus var. densiflorus), slender cottonweed, Cali<strong>for</strong>nia<br />
plantain (<strong>Plant</strong>ago erecta), pine bluegrass (Poa secunda), notchleaf clover (Trifolium bifidum), and small fescue<br />
(Vulpia microstachys). Species associated with the Micropus cali<strong>for</strong>nicus alliance included blowwives, yarrow<br />
(Achillea millefolium), jeweled onion (Allium serra), pale western larkspur (Delphinium hesperium), bottlebrush<br />
squirreltail (Elymus elymoides), Cali<strong>for</strong>nia melicgrass (Melica cali<strong>for</strong>nica), small flowered needlegrass (Nassella<br />
lepida), Cali<strong>for</strong>nia plantain, pine bluegrass, wireweed (Rigiopappus leptocladus), and small fescue.<br />
Apocynum cannabinum Provisional Alliance<br />
We observed large stands of Indian hemp (Apocynum cannabinum), an uncommon species with ethnobotanical<br />
significance, along the upper reaches of Rocky <strong>Creek</strong>. Whether these native assemblages were large enough to<br />
constitute an actual alliance is uncertain, but they are clearly important examples of Cali<strong>for</strong>nia’s native vegetation.<br />
Juncus ensifolius Provisional Alliance<br />
In the southern part of the wilderness near Brushy Sky High on serpentine soils, adjacent to a spring within a<br />
Sargent cypress (Hesperocyparis sargentii) woodland, we encountered a monoculture of three-stamened rush<br />
(Juncus ensifolius). Again, it is unclear whether this occurrence was large enough to constitute an alliance.<br />
Nonnative Unpublished Alliances<br />
Two non-native species, Ravenna grass (Saccharum ravennae) and medusahead (Taeniatherum caput-medusae),<br />
reach abundance levels high enough to constitute consideration as alliances. Ravenna grass is a regional weed<br />
problem (Thomsen and Meyer 2007), <strong>for</strong>ming extensive stands along <strong>Cache</strong> <strong>Creek</strong>, including areas of the<br />
Wilderness. Some of the prairie-grassland assemblages within the Wilderness support large stands of<br />
Medusahead. As this species is a common dominant in Cali<strong>for</strong>nia grasslands, it is unclear why Medusahead was<br />
not included as a non-native “semi-natural” alliance within the new 2009 Cali<strong>for</strong>nia Manual of Vegetation.<br />

UNCLASSIFIED ASSEMBLAGES AND SIGNIFICANT BOTANICAL FEATURES<br />
Problematic from a classification perspective were the extensive stands of mixed serpentine and non-serpentine<br />
chaparral that we encountered in the Wilderness. Since “membership rules” <strong>for</strong> shrub alliances often require one<br />
species to cover at least 50% of a given stand, the diverse mixtures of species that exist within some observed<br />
stands of mixed chaparral defy classification into discrete single-species alliance units. Mixed serpentine<br />
chaparral in the Wilderness typically included the following assemblage of shrub species: whiteleaf manzanita<br />
(Arctostaphylos viscida), Jepson ceanothus (Ceanothus jepsonii), toyon (Heteromeles arbutifolia), buckthorn and<br />
relatives (Rhamnus spp.), leatheroak (Quercus durata), chamise (Adenostoma fasciculatum), Interior silktassel<br />
(Garrya congdonii), Cali<strong>for</strong>nia bay (Umbellularia cali<strong>for</strong>nica), poison oak (Toxicodendron diversifolium), and, in<br />
places, cypress (Hesperocyparis spp.). Perhaps the extreme example of this was encountered in a two-acre area of<br />
serpentine-influenced soil near Brushy Sky High where we observed 17 different shrub species without any<br />
tendency towards dominance by one or more shrubs (see photo Appendix C). In addition to those already listed<br />
above <strong>for</strong> mixed serpentine chaparral, this area included the following shrubs: redbud, mountain mahogany,<br />
Cali<strong>for</strong>nia ash (Fraxinus dipetala), chaparral pea (Pickeringia montana), shrub oak (Quercus berberidifolia), and<br />
snowdrop bush (Styrax officinalis var. redivivus). Grasses and <strong>for</strong>bs associated with this area included:<br />
bottlebrush squirreltail, Cali<strong>for</strong>nia fescue (Festuca cali<strong>for</strong>nica), golden fairy lantern (Calochortus amabilis), soap<br />
plant (Chlorogalum pomeridianum), peregrine thistle (Cirsium cymosum), red ribbons (Clarkia concinnum),<br />
woolly sunflower (Eriophyllum lanatum), dwarf flax (Hesperolinon spp.), phlox-leaved bedstraw (Galium<br />
andrewsii), lomatium (Lomatium spp.), coyote mint (Monardella villosa), and blue-eyed grass (Sisyrinchium<br />
bellum).<br />
Similarly, a native prairie on serpentine soil just above Rocky <strong>Creek</strong> with nine native grasses and a rich<br />
assortment of <strong>for</strong>bs (see photo Appendix C) is another example of a rare native plant assemblage that doesn’t fall<br />
within any alliance status but warrants recognition as another significant botanical feature within the Wilderness.<br />
Native grasses encountered in this prairie were: woodland brome (Bromus laevipes), blue wildrye (Elymus<br />
glaucus), bottlebrush squirreltail, Roemer’s fescue (Festuca idahoensis var. roemeri), meadow barley (Hordeum<br />
brachyantherum), creeping wildrye (Leymus triticoides), purple needlegrass (Nassella pulchra), pine bluegrass,<br />
and small fescue. Associated <strong>for</strong>bs included: Cali<strong>for</strong>nia dandelion (Agoseris grandiflora), narrow-leaved onion<br />
(Allium amplectens), narrow leaf milkweed (Asclepias fascicularis), harvest brodiaea (Brodiaea elegans), yellow<br />
mariposa (Calochortus superbus), soap plant, peregrine thistle, bird’s beak (Cordylanthus sp.), hayfield tarweed<br />
(Hemizonia congesta ssp. luzulaefolia), little hareleaf (Lagophylla minor), short-podded lotus (Lotus humistratus),<br />
Chilean birdfoot trefoil (Lotus wrangelianus), chick lupine, slender cottonweed, yampah (Perideridia sp.),<br />
buttercup (Ranunculus sp.), fringed checkerbloom (Sidalcea diploscypha), blue-eyed grass, clover species, narrow<br />
leaf mule ears (Wyethia angustifolia), and death camas (Zigadenus sp.).<br />

Special-Status <strong>Plant</strong>s Survey 10 December, 2010
We encountered extensive serpentine barrens with reddish serpentine soils near Brushy Sky High; this was one of<br />
the most significant finds of the survey. The dry slopes of the interior of the eastern side of the barrens were<br />
mostly devoid of vegetation with the exception of two species of jewelflower (Streptanthus brachiatus and S.<br />
breweri) and three species of buckwheat (Eriogonum nervulosum, E. nudum and E. dasyanthemum). Serpentine<br />
milkweed was observed in one area, the only known location in the Wilderness. Some of the drainages within the<br />
barrens have an abundance of water, including several waterfalls. The serpentine riparian flora associated with the<br />
drainages located in the interior and western side of the barrens included the shrubs western azalea<br />
(Rhododendron occidentalis), Brewer’s willow (Salix breweri), spicebush (Calycanthus occidentalis), and<br />
Cali<strong>for</strong>nia buckthorn (Rhamnus tomentella); the mixed herbaceous layer included: angelica (Angelica spp.),<br />
Cleveland’s ragwort, Cleveland’s milkvetch, Van Houtte’s columbine (Aquilegia eximia) , two tooth sedge<br />
(Carex serratodens), stream orchid (Epipactus gigantean), and goldenrod (Solidago). Within parts of this area,<br />
two tree species were co-dominant and represented a previously undocumented alliance association: knobcone<br />
pine (Pinus attenuata)-Sargent cypress (Hesperocyparis sargentii).<br />
SPECIAL-STATUS PLANTS RESULTS<br />
Special-status plants are defined as plants that are legally protected or that are otherwise considered sensitive by<br />
federal, state, or local resource conservation agencies and organizations. Special-status plant taxa are species,<br />
subspecies or varieties that fall into one or more of the following categories, regardless of their legal or protection<br />
status:<br />
► Officially listed by the state of Cali<strong>for</strong>nia or the federal government as Endangered, Threatened or Rare;<br />
► A candidate <strong>for</strong> state or federal listing as Endangered, Threatened or Rare;<br />
► Taxa which meet the criteria <strong>for</strong> listing, even if not currently included on any list, as described in Section<br />
15380 of the Cali<strong>for</strong>nia Environmental Quality Act (CEQA) Guidelines;<br />
► Taxa designated as a special-status, sensitive or declining species by other state or federal agencies or<br />

Based on the pre-field investigation, 23 special-status plants (Rare <strong>Plant</strong> Rank 1B or state- or federallyendangered)<br />
were identified as having potential to occur in the Wilderness. Appendix A provides a list of these<br />
species along with in<strong>for</strong>mation about their listing status, habitat, distribution, flowering period, and potential to<br />
occur in the Wilderness (CNPS 2010; CNDDB 2010; CCH 2010).<br />
Eight Rare <strong>Plant</strong> Rank 1B special-status plants were encountered during the 2010 field survey (Figs. 3-5):<br />
Jepson’s milkvetch (Astragalus rattanii var. jepsonianus), round-leaf stork’s bill (Cali<strong>for</strong>nia macrophyllum),<br />
Snow Mountain buckwheat (Eriogonum nervulosum), adobe lily (Fritillaria pluriflora), Hall’s layia (Harmonia<br />
hallii), drymary dwarf-flax (Hesperolinon drymarioides), Colusa tidy-tips (Layia septentrionalis), and jewel<br />
flower (Streptanthus brachiatus). In addition six Rare <strong>Plant</strong> Rank 4 plants were documented (Figs. 3-5):<br />
Cleveland’s ragwort (Packera clevelandii), serpentine collomia (Collomia diversifolia), serpentine milkweed<br />
(Asclepias solanoana), bare monkey flower (Mimulus nudatus), swamp larkspur (Delphinium uliginosum), and<br />

RARE PLANT RANK 1B PLANTS:<br />
Jepson’s Milkvetch<br />
Jepson’s milkvetch (Astragalus rattanii var. jepsonianus) is a member of the Fabaceae family and is a Rare <strong>Plant</strong><br />
Rank 1B.2 plant (CNPS 2010). It is an annual plant with a slender, decumbent to erect stem to 30 cm tall,<br />
compound leaves with seven to nine blunt-tipped leaflets, and flowers borne in heads of four to nine flowers. The<br />
hairs on the plant are often blackish. The flowers are purple and white (Hickman 1993), and the plants bloom<br />
from March through June (CNPS 2010). Jepson’s milkvetch is often found on serpentine soils at 350 – 600 m in<br />
elevation within the southern area of the Inner North Coast Ranges of Cali<strong>for</strong>nia (Hickman 1993). It grows in<br />
chaparral, cismontane woodland, and valley and foothill grasslands plant communities (CNPS 2010). It has been<br />
found in Colusa, Glenn, Lake, Napa, Tehama, Yolo and Mendocino counties (CNPS 2010, CCH 2010, CNDDB<br />
2010).<br />
<strong>Cache</strong> <strong>Creek</strong> Wilderness <strong>UC</strong> <strong>Davis</strong> <strong>Center</strong> <strong>for</strong> <strong>Plant</strong> <strong>Diversity</strong><br />
Special-Status <strong>Plant</strong>s Survey 15 December, 2010
We encountered Jepson’s milkvetch during April, May and June, 2010 in several areas of the Wilderness (Figs. 3<br />
and 4). The first occurrence was a diffuse population found April 24 on the serpentine-influenced alluvial deposits<br />
of the lower reaches of Rocky <strong>Creek</strong> at approximately 900 feet. Numerous plants were observed in small clusters<br />
of approximately ten plants along the sides of the creek; all plants were in flower. The second occurrence was a<br />
very small population (three flowering plants) observed on April 24 on a gravel terrace on the south side of <strong>Cache</strong><br />
<strong>Creek</strong> east of the confluence of the north and south <strong>for</strong>ks. The third and fourth occurrences were on serpentine<br />
deposits on east-facing slopes above the north <strong>for</strong>k of <strong>Cache</strong> <strong>Creek</strong> at approximately 1,100 -1,250 feet. The third<br />
occurrence, which consisted of approximately 5,000 flowering plants, was encountered on May 5. The fourth<br />
occurrence, encountered on June 9, consisted of fewer than 100 fruiting plants. The fifth occurrence was located<br />
at approximately 2500 feet on serpentine barrens near the southern boundary of the Wilderness to the west of<br />
Rocky <strong>Creek</strong>; this small population of ca. 50 plants was in flower and fruit.<br />
Where we observed Jepson’s milkvetch in the Wilderness, it grew in areas where vegetation is nearly absent or in<br />
sparse annual grassland assemblages. The first and second occurrences along <strong>Cache</strong> and Rocky <strong>Creek</strong>s suggest<br />
that the seeds were being washed down from upper slopes and deposited at the creek edges. There<strong>for</strong>e, larger<br />
populations probably occur elsewhere in the Wilderness on serpentine influenced slopes above the creeks.<br />
Round-leaf stork’s bill<br />
Round-leaf stork’s bill (Cali<strong>for</strong>nia macrophyllum <strong>for</strong>merly known as Erodium macrophyllum) is a member of the<br />
geranium family (Geraniaceae) and is a Rare <strong>Plant</strong> Rank 1B.1 plant (CNPS 2010). It is an inconspicuous, winter<br />
annual that has simple, kidney-shaped, basal leaves with reddish veins. The stem is less than 5 cm tall and<br />
glandular-puberulent. The small, white flowers self-pollinate and are very short-lived, generally lasting <strong>for</strong> only<br />
one day. The fruits develop quickly and have a distinctive beak (Hickman 1993, Gillespie 2005). Round-leaf<br />
stork’s bill is found on open sites within grassland and shrubland communities at elevations below 1200 m (CNPS<br />
2010) and is restricted to clay soils (Gillespie 2005). The species is broadly distributed, but rarely encountered; in<br />
some cases, county records are based on collections made in the first half of the 20 th century (CCH 2010). Its<br />
current and historical distribution encompasses the Sacramento Valley, northern San Joaquin Valley, central<br />
western Cali<strong>for</strong>nia, the southern coast of Cali<strong>for</strong>nia and the northern Channel Islands (specifically Santa Cruz<br />
Island) (Hickman 1993). It has been documented in Alameda, Butte, Contra Costa, Colusa, Fresno, Glenn, Kings,<br />
Kern, Lake, Lassen, Los Angeles, Merced, Monterey, Napa, Riverside, Santa Barbara, San Benito, Santa Clara,<br />
San Diego, San Joaquin, San Luis Obispo, San Mateo, Solano, Sonoma, Stanislaus, Tehama, Ventura, and Yolo<br />
counties, as well as Baja Cali<strong>for</strong>nia and Oregon (CNPS 2010, CCH 2010, CNDDB 2010). Round-leaf stork’s bill<br />
blooms from March through May.<br />
We encountered Round-leaf stork’s bill in full flower on April 3, 2010 along the eastern boundary of the<br />
Wilderness, adjacent to the BLM Bear <strong>Creek</strong> Ranch. We found four occurrences on the west side of the Ridge<br />

Special-Status <strong>Plant</strong>s Survey 16 December, 2010
Trail and one on the east side (Fig. 5). In all cases, the plants were growing on 5-30% slopes in deep, clay soils<br />
within 50 feet of a drainage. In many cases, very deep cattle hoof prints were visible where the plants were<br />
growing, indicating that the soil had been very wet. In most cases, white mudstone rocks were present on the soil<br />
surface. Surrounding vegetation was either annual grassland or open, blue oak woodland; in all cases ground<br />
cover was less than 50%, with the plants occurring in open soil. Common associates included annual grasses,<br />
especially medusahead, common lomatium (Lomatium utriculatum), redstem filaree (Erodium cicutarium),<br />
shortfruit stork’s bill (Erodium brachycarpum), broad leaf filaree (Erodium botrys), cut leaved geranium<br />
(Geranium disssectum), few flowered evax (Hesperevax sparsiflora), and smooth cat’s ear (Hypochaeris glabra).<br />
Populations ranged from 500 to more than 5000 individuals.<br />
Snow Mountain buckwheat<br />
Snow Mountain buckwheat (Eriogonum nervulosum), a member of the buckwheat family (Polygonaceae), is a<br />
Rare <strong>Plant</strong> Rank 1B.2 plant (CNPS 2010). It is a matted subshrub to 15 cm tall with small leaves (that are woolly<br />
on the underside) arranged in rosettes. The small yellow-to-reddish flowers are arranged in rounded umbellate<br />
clusters (Hickman 1993). The species is found on serpentine barrens or outcrops at 300 – 2100 m in elevation<br />
(Hickman 1993, CNPS 2010). It is known to occur in the North Coast Ranges in Colusa, Glenn, Lake, Napa,<br />
Sonoma, and Yolo counties (CCH 2010, CNPS 2010). Snow Mountain buckwheat blooms from June to<br />
September (CNPS 2010).<br />
We documented Snow Mountain buckwheat on an extensive system of serpentine barrens at 2,200-2,400 feet in<br />
elevation near the southern edge of the Wilderness on June 25, 2010 (Fig. 4). Thousands of plants were present,<br />
occupying numerous hillslopes and ridges. Approximately 30-70% of the plants were in flower, depending on the<br />
subpopulation. Common associates were Socrates Mine jewelflower (Streptanthus brachiatus), naked buckwheat<br />
(Eriogonum nudum) and chaparral buckwheat (E. dasyanthemum); serpentine milkweed (Asclepias solanoana)<br />
was also present in one area.<br />
Adobe Lily<br />
Adobe lily (Fritillaria pluriflora), a member of the lily family (Liliaceae), is a Rare <strong>Plant</strong> Rank 1B.2 plant (CNPS<br />
2010). It is a perennial geophyte that emerges each spring from an underground bulb. The stem is 1.5 – 4.5 dm in<br />
length and has 3 – 10 alternately-arranged leaves that are clustered near the ground. The flowers are nodding and<br />
pinkish purple in color. The species is found on adobe soils of the interior foothills (Hickman 1993) at elevations<br />
of less than 705 m in chaparral, cismontane woodland, and valley grassland vegetation types (CNPS 2010).<br />
Adobe lily’s distribution encompasses the Inner North Coast Ranges, Sierra Nevada Foothills, the perimeter of the<br />
Sacramento Valley, and southern Oregon (Hickman 1993), and it has been documented in eleven Cali<strong>for</strong>nia<br />

counties: Butte, Colusa, Glenn, Lake, Napa, Solano, Tehama, Mendocino and Yolo (CNPS 2010, CCH 2010,<br />
CNDDB 2010). Adobe lily blooms from February to April (CNPS 2010).<br />
In the Wilderness, we encountered Adobe lily at 1,300 to 1,400 feet in elevation in a serpentine meadow to the<br />
west of the Rocky <strong>Creek</strong> drainage (Fig. 3). The location had deep clay soils, a flowing stream, and numerous<br />
seeps. Adobe lily was concentrated on the edges of rocky outcrops in gentle (10-30%) slopes within grassland.<br />
Associates included medusa head and other native and nonnative annual grasses, buttercup (Ranunculus sp.), and<br />
larkspur (Delphinium sp.). We accessed this location on March 3, 2010 when the Adobe lily plants were just<br />
beginning to emerge and few were in flower. At that time, we estimated that there were approximately 400 plants<br />
in numerous subpopulations, although this number probably underestimates the population size. We attempted to<br />
return to this site twice to re-estimate the size of the population and search <strong>for</strong> other special-status plants but could<br />
not cross <strong>Cache</strong> <strong>Creek</strong>.<br />
Hall’s Layia (Harmonia hallii)<br />
Hall’s layia (Harmonia hallii or Madia hallii), a member of the tarweed tribe in the daisy family (Asteraceae), is a<br />
Rare <strong>Plant</strong> Rank 1B.2 plant (CNPS 2010). It is a glandular, annual herb to 18 cm with few branches and leaves<br />
crowded into whorl-like clusters. Its yellow flowers are in a small head, and its fruits lack any appendages<br />
(Hickman 1993). Hall’s layia is found on serpentine barrens in open chaparral between 500 and 900 meters in<br />
elevation and has been documented in Colusa, Lake, Napa, and Yolo counties. It blooms from April to June<br />
(CNPS 2010).<br />
Hall’s layia was encountered in only one restricted location at 2,565 feet in elevation in the center of and along<br />
the sides of an unpaved road through serpentine chaparral near the southern boundary of the Wilderness (Fig. 4).<br />
The road on which it was located descends from Stephen Gilardi’s property to <strong>Cache</strong> <strong>Creek</strong>. This segment of the<br />
road had a southeastern exposure and a warmer microclimate than surrounding areas. The chaparral vegetation<br />
included Jepson’s ceanothus (Ceanothus jepsonii), chaparral buckwheat (Eriogonum dasyanthemum), sickleleaf<br />
onion (Allium falcifolium), leather oak (Quercus durata), whiteleaf manzanita (Arctostaphylos viscida), and<br />
drymary dwarf-flax. There were approximately 100 plants in full flower.<br />
Drymary Dwarf-flax<br />
Drymary dwarf-flax (Hesperolinon drymarioides) is a member of the linen family (Linaceae) and a Rare <strong>Plant</strong><br />
Rank 1B.2 plant. It is a delicate, annual herb that grows to 25 cm tall and has whorled leaves. Its small, white<br />
flowers are arranged in a diffuse, <strong>for</strong>king inflorescence. Its distribution is concentrated in the inner North Coast<br />
Ranges. It has been documented in Colusa, Glenn, Lake, Napa, and Yolo counties. It occurs on serpentine soils in<br />
coniferous <strong>for</strong>est, chaparral, cismontane woodland, and valley and foothill grassland at 100 – 1130 m in elevation.<br />
Drymary dwarf-flax blooms from May to August.<br />
<strong>Cache</strong> <strong>Creek</strong> Wilderness <strong>UC</strong> <strong>Davis</strong> <strong>Center</strong> <strong>for</strong> <strong>Plant</strong> <strong>Diversity</strong><br />
Special-Status <strong>Plant</strong>s Survey 18 December, 2010
We encountered Drymary dwarf-flax near the southern Wilderness boundary on May 12 and June 25, 2010 (Fig.<br />
4). It occurs there between 2,500 and 2,600 feet in elevation north and west of Stephen Gilardi’s property. It was<br />
growing on open, disturbed serpentine soils along unpaved roads within chaparral. Chaparral associates are the<br />
same as listed above <strong>for</strong> Hall’s layia. Herbaceous associates included Hall’s layia, sickleleaf onion, chaparral<br />
willowherb (Epilobium minutum), short podded lotus (Lotus humistratus), and four-petaled pussypaws<br />
(Calyptridium quadripetalum). The population was extensive and consisted of thousands of plants. On the May 12<br />
visit, all plants were vegetative. On the June 25 visit, all plants were in flower.<br />
Colusa Tidy-tips<br />
Colusa tidy-tips (Layia septentrionalis) is a member of the tarweed tribe in the daisy family (Asteraceae) and a<br />
Rare <strong>Plant</strong> Rank 1B.2 plant. It is an annual herb that grows to 35 cm tall and has sticky, glandular hairs on its<br />
stem, leaves, and yellow flower heads. An important character that separates it from other species of tarweed is<br />
having woolly hairs at the base of its fruit appendages. Its distribution is concentrated in the North Coast Ranges,<br />
extending east to Sutter County. It has been documented in Colusa, Glenn, Lake, Mendocino, Napa, Sonoma,<br />
Sutter, Tehama, and Yolo counties. It occurs in chaparral, cismontane woodland, valley and foothill grassland on<br />
sandy or serpentine-influenced soils at 100 – 1095 m in elevation. Colusa tidy-tips blooms from April to May.<br />
We encountered Colusa tidy-tips in two areas of the Wilderness. The first occurrence was found on April 24,<br />
2010 at ca. 1,100 ft in elevation in annual grassland within blue oak woodland on a peninsular ridge that protrudes<br />
into the <strong>Cache</strong> <strong>Creek</strong> watershed on the south side of the creek west of the confluence of Rocky and <strong>Cache</strong> <strong>Creek</strong>s<br />
(Fig. 3). The soil type did not appear to be derived from serpentine, but downslope from the occurrence, on the<br />
east side of the ridge, serpentine deposits were evident on the south side of <strong>Cache</strong> <strong>Creek</strong>. The population<br />
consisted of ca. 300 plants with most plants in full flower.<br />
The second occurrence was encountered on May 5, 2010 between 1140 and 1238 feet in elevation on a northeastfacing<br />
slope of a serpentine-influenced ridge on the west side of the north <strong>for</strong>k of <strong>Cache</strong> <strong>Creek</strong> (Fig. 3). The<br />
Colusa tidy-tips plants were growing in the partial shade of a blue oak woodland adjacent to an open serpentine<br />
barrens with sparse annual grasses. The population consisted of at least 10,000 plants and was growing with<br />
jeweled onion (Allium serra), slender tarweed (Madia gracilis), Ithuriel’s spear (Triteleia laxa), succulent lupine<br />
(Lupinus succulentus), and foothill clover (Trifolium ciliolatum).<br />
Socrates Mine Jewelflower<br />
Socrates Mine jewelflower (Streptanthus brachiatus), a member of the mustard family (Brassicaceae), is a Rare<br />
<strong>Plant</strong> Rank 1B.2 plant (CNPS 2010). This species has been broken down into two rare subspecies in the past (both<br />
List 1B.2), but these subspecies are no longer recognized (Jepson Herbarium 2010). Samples of Socrates Mine<br />

jewelflower that we encountered in the Wilderness were sent to the taxonomic expert of this group, Ishan Al-<br />
Shebaz, at the Missouri Botanical Garden <strong>for</strong> determination.<br />
Socrates Mine jewelflower is a biennial herb to 60 cm tall that is branched near the base; characteristically, it<br />
produces rosettes of leaves the first year and then produces a flowering stalk the next year. The flowers are urnshaped<br />
with yellowish-purple sepals and white and purple petals. The fruits have constrictions between the seeds<br />
(Jepson Herbarium 2010). The species is found on serpentine barrens or outcrops at 600 – 950 m in elevation<br />
(Jepson Herbarium 2010). It is known to occur in the North Coast Ranges in Lake, Napa, and Sonoma counties<br />
(CCH 2010, CNPS 2010). Socrates mine jewelflower blooms from May to July (CNPS 2010).<br />
Socrates Mine Jewel flower was encountered on an extensive system of serpentine barrens at ca, 2,200-2,500 feet<br />
in elevation near the southern edge of the Wilderness in June, 2010 (Fig. 4). Thousands of plants were present on<br />
numerous hillslopes and ridges. Approximately 30-70% of the plants were in flower, depending on the<br />
subpopulation. Common associates were naked buckwheat (Eriogonum nudum) and chaparral buckwheat (E.<br />
dasyanthemum); in some areas serpentine milkweed (Asclepias solanoana), Brewer's jewelflower (Streptanthus<br />
breweri), and Snow Mountain buckwheat grew with Socrates Mine jewelflower.<br />
RARE PLANT RANK 4 PLANTS<br />
Serpentine Milkweed<br />
Serpentine milkweed (Asclepias solanoana), a perennial herb in the dogbane/milkweed family, Apocynaceae, was<br />
encountered on one slope of the serpentine barrens near Brushy Sky High on June 25, 2010 (Fig. 4). This<br />
prostrate, grey-leaved plant was present in small numbers growing with jewelflower and buckwheat species.<br />
Serpentine milkweed is known to occur in Colusa, Glenn, Lake, Mendocino, Napa, Shasta, Sonoma,<br />
Tehama, Trinity, and Yolo counties, usually on serpentine soils, from 230 – 1860 meters; in the various parts of it<br />
range, serpentine milkweed is known to flower from May to August (CNPS 2010). The plants we observed were<br />
in full flower.<br />
Cleveland’s Milkvetch<br />
Cleveland’s milkvetch (Astragalus clevelandii), a perennial herb in the pea family, Fabaceae, was occasionally<br />
encountered along both Rocky <strong>Creek</strong> and the drainages of the serpentine barrens near Brushy Sky High on June<br />
16 and 25, 2010 (Fig. 4). This erect, pinnately-leaved plant was present in small numbers at the edges of creeks.<br />
Cleveland’s milkvetch is known to occur in Colusa, Lake, Napa, San Benito, Sonoma, Tehama, and Yolo<br />
counties, usually on serpentine soils, from 200 to 1500 meters; in the various parts of it range, Cleveland’s<br />
milkvetch is known to flower from June to September (CNPS 2010). None of the plants we encountered were in<br />
flower.<br />

Serpentine Collomia<br />
Serpentine collomia (Collomia diversifolia), in the phlox family, Polemoniaceae, was encountered on June 16 and<br />
25 in small numbers on gravelly, open, serpentine soils along the northern reaches of Rocky <strong>Creek</strong> and in the<br />
barrens area near Brushy Sky High (Fig. 4). This small, compact, pink-flowered, annual herb occurs on serpentine<br />
soils in Contra Costa, Colusa, Glenn, Lake, Mendocino, Napa, Shasta, Stanislaus, and Yolo counties from 300 to<br />
600 meters; in the various parts of its range, serpentine collomia is known to flower from May to June (CNPS<br />
2010). The plants we encountered were in fruit.<br />
Swamp Larkspur<br />
Swamp larkspur (Delphinium uliginosum), in the buttercup family, Ranunculaceae, was encountered on June 16,<br />
2010 in small numbers in a very wet meadow/seep along one small stretch of Rocky <strong>Creek</strong> where a tributary<br />
deposits serpentine alluvium on the eastern side of the creek (Fig. 4). This erect, purple-flowered perennial herb<br />
occurs in Colusa, Lake, Napa, and Siskiyou counties from 340 to 610 meters; swamp larkspur is known to flower<br />
from May to June (CNPS 2010). The plants were in full flower when encountered in June.<br />
Bare Monkey Flower<br />
Bare monkey flower (Mimulus nudatus) in the figwort family, Scrophulariaceae, was encountered in very small<br />
numbers in one serpentine seep within a Sargent cypress woodland near Brushy Sky High on June 25, 2010 (Fig.<br />
4). This small, yellow-flowered, annual herb occurs in Colusa, Lake, Mendocino, and Napa counties from 250 to<br />
700 meters; bare monkey flower is known to flower from May to June (CNPS 2010, and the plants we observed<br />
were in full flower.<br />
Cleveland’s Ragwort<br />
Cleveland’s ragwort (Packera clevelandii or Senecio clevelandii) in the daisy family, Asteraceae, was<br />
encountered in small numbers along drainages in the serpentine barrens area near Brushy Sky High on June 25,<br />
2010 (Fig. 4). This perennial herb with spoon-shaped basal leaves occurs in Colusa, Lake, and Napa counties<br />
from 365 to 900 meters; this species is known to flower from June to July (CNPS 2010), although it was not yet in<br />
flower during our June survey.<br />
CONCLUSIONS AND RECOMMENDATIONS<br />
Although, the 2010 survey was exploratory and limited in scope, we documented eight Rare <strong>Plant</strong> Rank 1B and<br />
six List 4 plants. Due to its remoteness and terrain, access into many areas was difficult, and some routes into the<br />
Wilderness were restricted due to the high water flows released into <strong>Cache</strong> <strong>Creek</strong> in May and June. Beyond what<br />
we observed, we are confident that other special-status plants occur within the Wilderness, or at least, additional<br />
<strong>Cache</strong> <strong>Creek</strong> Wilderness <strong>UC</strong> <strong>Davis</strong> <strong>Center</strong> <strong>for</strong> <strong>Plant</strong> <strong>Diversity</strong><br />
Special-Status <strong>Plant</strong>s Survey 21 December, 2010
populations of the special-status plants reported in this report. And while our vegetation alliance in<strong>for</strong>mation is<br />
provisional, eight of our suspected 25 alliances have either some global or state rarity, and others may constitute<br />
“unique stands” or remnant assemblages of herbaceous native vegetation that have lost ground throughout the<br />
state. The complexity of the geologic substrates, soils, and vegetation of the Wilderness warrants a more in-depth<br />
investigation on alliances, other vegetation assemblages, and rare plants.<br />
Priority areas <strong>for</strong> additional rare plant exploration are the serpentine soils of the Coast Range Ophiolite, such as<br />
those surrounding the Rocky <strong>Creek</strong> drainage, the serpentine barrens near Brushy Sky High, and the soils of<br />
Petrified Canyon. Also, there is a serpentine-influenced meadow with adobe lily on the west side of Rocky <strong>Creek</strong><br />
south of the Redbud Trail that deserves additional visits. At a minimum, we are sure that future investigators<br />
would find pink cream sacs (Castilleja rubicundula ssp. rubicundula) in that location, if the meadow could be<br />
accessed in May. In addition, the serpentine-influenced slopes surrounding the waterfall of Dead Man’s Canyon<br />
look very promising when viewed from across <strong>Cache</strong> <strong>Creek</strong>.<br />
