PURPOSE AND INTRODUCTION
Six species of rare plants endemic to California's central coast were identified by California
Department of Fish and Game (DFG) for development of recovery recommendations because of their
narrow distributions and immediate threats from coastal development (Table 1). The six rare species
described in this report are coastal dunes milkvetch (Astragalus tener var. till), Pacific Grove clover
(Tifoliurn polyodon), Monterey clover (Trifolium trichocalyx), Hickman's cinquefoil (Potentilla
hickmanii), Yadon's rein orchid (Piperia yadonii), and Gowen cypress (Cupresus goveniana var.
goveniana).
The purpose of this study was to:
■ collect baseline information to determine plant distribution, population, and habitat
characteristics and
■ develop site-specific protection and recovery recommendations to be incorporated into a
formal recovery plan for each of the six species.
This report provides essential information for development of protection and recovery
strategies to ensure long-term viability in the wild of these six coastal plant species. All six species
are of extremely limited distribution and are threatened throughout their ranges by residential and
resort development, aggressive exotic plant species, and recreational activities. The small and isolated
nature of the remaining populations makes them extremely vulnerable to elimination.
The tasks involved in this study included:
■ conducting thorough field surveys of suitable habitats on the Monterey Peninsula to
determine the distribution of the six species;
■ studying basic features of all occurrences to characterize habitat, soil types, predators,
competitors, and associated species;
■ developing recovery recommendations suitable for inclusion in a formal recovery plan;
and
■ preparing draft and final reports.
The "Methods" section of this report explains the survey strategy. Six sections that separately
describe each of the six target rare species are contained in the "Results and Recovery
Recommendations" section of this report. The "Concluding Remarks" section provides a summation
of conclusions. Appendices contain field survey notes, field data forms, and photographs of species
and habitats.

METHODS
Rare plant surveys were conducted in April-June 1995 by Jones & Stokes Associates botanists
and Jane Holte, a consulting botanist, under contract to Jones & Stokes Associates. The botanists
completed standard California native species field survey forms for DFG's Natural Diversity Data
Base (NDDB) for all rare plant occurrences encountered, including previously recorded known
occurrences. The project was initiated by conducting surveys of known occurrences of the species
with Vernal Yadon, Mary Ann Matthews, David Allen, and Joey Dorrell, individuals knowledgeable
of these species. Habitat characteristics were observed at the site of each occurrence to identify
common habitat patterns among occurrences of each species. Habitat characteristics include
vegetation type, soil type, hydrology indicators, evidence of predation, associated plant species,
potential competitors, and evidence of vegetation or ground disturbance. These habitat characteristics
were used to focus the surveys for new populations to sites most likely to support the species, to
identify threats, and to develop recovery recommendations.
The study area is shown in Figure 1. Specific locations of Jones & Stokes Associates survey
sites are shown in Figures 2-5. Each survey site is coded with a number in Figures 2-5 and the
number codes of these sites are used throughout the report as a quick reference to specific locations.
Survey sites were chosen based on specific combinations of geologic and vegetation features of sites
on the Monterey Peninsula and inland at Monterra Ranch. A geologic map of the Monterey Peninsula
at a scale of 1:24,000 (Dupre 1990) was used to identify sites of geomorphic surfaces correlated with
target plant occurrences. See Jones & Stokes Associates (1994a) for descriptions of the geomorphic
surfaces of the Monterey Peninsula and their relationship to soil and vegetation patterns. False-color
i,ifrared aerial photographs at a scale of 1:12,030 were used to identify sites supporting vegetation
appropriate for target species. As new occurrences of target species were identified, the habitat at
these sites was characterized and the definition of suitable habitat modified, if necessary.
Potential suitable habitat for coastal dunes milkvetch was identified as sites supporting
grassland habitat on the first marine terrace. Potential suitable habitat for Pacific Grove clover was
identified as sites supporting grassland habitat on the first through fourth marine terraces and swales
in dune formations. Potential suitable habitat for Monterey clover was identified as sites supporting
recently burned Monterey pine forest or pygmy forest on the fifth and sixth marine terraces and
intervening slopes. Potential suitable habitat for Hickman's cinquefoil was identified as sites
supporting grassland or open-canopied Monterey pine forest with grassy understory on the second
through fourth marine terraces.
Data on occurrences of Yadon's rein orchid were gathered from David Allen's surveys
conducted for the Pebble Beach Company (Allen pers. comm.) and from other sources (Natural
Diversity Data Base 1995). Known occurrences (Natural Diversity Data Base 1995, Allen pers.
comm.) of Yadon's rein orchid were surveyed and habitat was characterized by the Jones & Stokes
Associates botanists at The Nature Conservancy's (TNC's) Bloom Ranch Preserve, Huckleberry Hill
Preserve at the Presidio of Monterey, S.F.B. Morse Botanical Reserve, Huckleberry Hill Natural Area,
and Pebble Beach Equestrian Center. Data on occurrences at the Old Capitol Site and along Jack's
Peak Ranch were obtained by Jones & Stokes Associates from David Allen (Allen pers. comm.). The

Data on occurrences of, and habitat for Gowen cypress were gathered by Jones & Stokes
Associates during 1995 from site investigations and from file data from previous investigations of
Gowen cypress and pygmy forest habitat (Jones & Stokes Associates 1994a).
Taxonomic nomenclature used in this report follows Hickman (1993). Common names for
species were derived from Hickman (1993), U.S. Department of Agriculture (1986), and Matthews
(1992).
All onsite surveys were conducted with prior permission from landowners. Potential habitat
on private land for which entry approval had not been received was surveyed from offsite to assess
habitat suitability for target species.

Coastal Dunes Milkvetch
Description and Taxonomy
Coastal dunes milkvetch is a small annual in the legume family (Fabaceae). Stems are 2-12
centimeters (cm) long. The leaves are pinnately compound and 2-7 cm long, with seven to 13 leaflets.
Leaflets are wedgelike to oblanceolate and 5-16 millimeters (mm) long. Flowers are borne in
subcapitate racemes with two to seven flowers per inflorescence. The petals are purple. The fruit is
a straight or curved legume 6-14 mm long. (Hickman 1993, California Native Plant Society 1987.)
Coastal dunes milkvetch is conspecific with alkali milkvetch (Astragalus tener var. tener),
which occurs inland in alkaline, grassy flats in the Central Valley, San Francisco Bay region, and the
lower Salinas Valley (California Native Plant Society 1987). Coastal dunes milkvetch is distinguished

May 19%
from alkali milkvetch by its smaller banner (5.2-6 mm versus 7.8-11.8 mm in length) and typically
fewer seed per fruit (five tol 1 seeds/fruit versus eight to 16 seeds/fruit) (Hickman 1993). Black hairs
on the calyx are also a distinguishing characteristic (Yadon pers. comm.).
Listing Status
Coastal dunes milkvetch was proposed for federal listing as endangered under the Endangered
Species Act in August 1995 (60 FR 148:39326-39337, August 2, 1995). It was listed as endangered
under the California Endangered Species Act in February 1982. The California Native Plant Society
(CNPS) considers this species to be rare and endangered in California (List I B) (Skinner and Pavlik
1994).
Distribution
Coastal dunes milkvetch historically occurred in a disjunct distribution at coastal sites in
Monterey, Los Angeles, and San Diego Counties. The Los Angeles County occurrences are
presumed extirpated and the San Diego County occurrences have not been documented since the
1970s, even though efforts were made in the 1980s to relocated them (Skinner and Pavlik 1994;
Ferreira 1995; Natural Diversity Data Base 1995). Only one extant occurrence of coastal dunes
milkvetch is known, on Seventeen Mile Drive near Bird Rock (Sites 11 and 12) on the Monterey
Peninsula (Figure 6). This occurrence includes eleven scattered patches of plants, totaling
approximately 4,000 individuals, on each side of Seventeen Mile Drive, along Bird Rock Road, and
at a horse jumping area on the Monterey Peninsula Country Club Golf Course (Table 2). Prior to this
study, coastal dunes milkvetch had not been identified at the horse jump area and along Bird Rock
Road in survey Site 12. Milkvetch at Sites 11 and 12 is treated here as a single fragmented
occurrence. Eleven patches that support milkvetch were identified within the two sites of this
occurrence (Figure 6; Appendix B).
Ecology and Habitat Requirements
Coastal dunes milkvetch occurs on the first marine terrace, primarily on Antioch soils, with
a few small stands on compacted Sheridan soils. The milkvetch occurs on moist sites within coastal
prairie habitat preferring shallow depressions, swales, and the intermound areas in mima mound
terrain. At the fenced exclosure on Site 11, the soil is the Antioch series and supports a sandy A
horizon with a dense clay B horizon at about 23-inches depth. The clay layer is mottled, indicating
periodic saturation and drying. Because of the exposure to ocean spray, it appears that coastal dunes
milkvetch is likely tolerant of slightly saline soil conditions.
Coastal dunes milkvetch occurs in vegetation of very low stature, less than 6 inches tall and
mostly less than 4 inches tall. Vegetative cover is moderate to high, encompassing about 80%-100%
of the surface but with little overlapping of plant shoot systems. Shoot competition for space and light
appears to be low where the milkvetch grows. Surrounding mound areas support taller, grassdominated vegetation with more dense cover. Coastal dunes milkvetch is found at sites dominated

by cut-leaved plantain (Plantago coronopis), California oatgrass (Danthonia californica), and tufted
hairgrass (Deschampsia cespitosa ssp. holciformis). The occurrence of cut-leaved plantain and
goldfields (Lasthenia minor) is a good indicator of appropriate microhabitat conditions for the
milkvetch. Other plant species associated with the milkvetch are listed on the data forms in
Appendix B.
Coastal dunes milkvetch flowers from March to May. Pollinators were not observed but,
based on the floral structure, small bees are likely pollinators.
Reasons for Decline and Threats to Survival
Urban development has resulted in the loss of historical occurrences of coastal dunes
milkvetch in southern California and possibly historical occurrences in Monterey. The construction
of Seventeen Mile Drive and the Monterey Peninsula Country Club Golf Course resulted in the loss
of individuals and habitat and fragmented the Bird Rock population of milkvetch.
Coastal dunes milkvetch occurs on land owned by the Pebble Beach Company west of
Seventeen Mile Drive (Site 11) and on land owned by the Monterey Peninsula Country Club east of
Seventeen Mile Drive (Sites 11 and 12).
Threats to the survival of coastal dunes milkvetch includes trampling, mowing, modifications
in hydrology, and competition from other plant species. In 1989, Pebble Beach Company constructed
an exclosure fence around part of the coastal dunes milkvetch population at Bird Rock to control
access to the site. Competition from larger or more aggressive plants may threaten milkvetch
populations. Pansa sedge (Carex pansa) is spreading within the fenced area and could overgrow
milkvetch habitat. African ice plant (Carpobrotus edule) growing in the immediate vicinity could
expand into milkvetch habitat and crowd out the milkvetch. The non-native cut-leaf plantain, a plant
of similar size to the milkvetch, grows mixed with most of the milkvetch population and could
represent a competitive threat (Ferreira 1995, Yadon pers. comm., Dorrell pers. comm.).
Improvements or maintenance of Seventeen Mile Drive could result in hydrologic modifications to
coastal dunes milkvetch habitat (e.g., increased ponding of runoff could degrade milkvetch habitat).
Use of trails by pedestrians, horses, golf carts, and dogs result in trampling of milkvetch plants and
horse races also take place on the trail. The milkvetch occurs on the trail side and not in the heavily
used trail path. Any increase in use of the trail could result in the loss of plants and habitat. Mowing
at the horse jumping area on the Monterey Peninsula Country Club Golf Course may be removing
milkvetch plants.
Because it occurs at only one location, coastal dunes milkvetch is susceptible to extinction
from random catastrophic events. Examples of possible events that could result in extinction are the
introduction of a disease into the population, or a major storm that results in wave erosion of the
terrace or tidal surges onto the site. Increases in recreational use or new development could quickly
eliminate this species.

Final Recovery Strategies for Six Coastal Plant Species
on the Monterey Peninsula
May 1996
Recommendations for Habitat and Population Recovery
Recovery of coastal dunes milkvetch should focus on establishment of new populations at
protected sites. Additional protection measures for the existing population are needed, but are mostly
infeasible. The extant Bird Rock population has maintained itself at its existing site for at least the last
90 years and likely much longer. This site, however, has been seriously degraded by the construction
of roads, parking lots, a golf course, and trails; invasion by non-native plants; and exposure to the
activities of people including tourism, beach going, golfing, horseback riding, and dog walking.
Property owners should be encouraged to control access at this site to avoid or reduce adverse affects
on coastal dunes milkvetch. Approximately 4,000 individuals of coastal dunes milkvetch were
observed during Jones & Stokes Associates surveys in 1995. Only about 2,300 of these individuals
were within the fenced exclosure on the Pebble Beach Company property and this exclosure offers
only limited protection of plants. The following measures could be taken to protect the existing
milkvetch population:
■ construct post and cable fence between trails and milkvetch populations;
■ discourage horse racing on the trail, especially during the winter and spring months when
the ground is wet and the plants are growing;
■ control invasive species such as African ice plant and pansa sedge.
DFG should approach the Pebble Beach Equestrian Center and explore the possibility of
changing the timing of the Los Altos Hunt from its present scheduling in mid-spring to a July or
August running. Approximately 200 horses run in this annual race and the trampling during flowering
and fruiting of milkvetch could reduce reproduction.
A program to control invasive species should be initiated at the Bird Rock site. Control of
pansa sedge and African ice plant with herbicides or hand pulling would increase suitable habitat for
the milkvetch. Pansa sedge should be removed from within the exclosure. African ice plant should
be removed from within the exclosure, sites north and south of the exclosure, and suitable milk vetch
habitat along the east side of Seventeen Mile Drive. DFG should request that the Pebble Beach
Company make these weed control actions an ongoing part of their maintenance program at these
sites.
A program should be initiated to introduce and establish populations of coastal dunes
milkvetch at other sites on the first marine terrace that support suitable soil and vegetation conditions.
Coastal dunes milkvetch can be successfully grown from seed in pots (Yadon pers. comm.). Several
sites (Sites 25, 27, 28, 29, and 30) at Point Lobos State Reserve meet these criteria and should be
investigated as potential establishment sites (Figure 7). Sites 25 and 29 appear to offer the highest
quality suitable habitat. Site 29 appears to be especially promising because the site is on the first
marine terrace immediately adjacent to the beach, Antioch soils with mima mound relief are extensive
there, and many of the common associates of coastal milkvetch are found in the intermound habitat.
DFG should coordinate with California Department of Parks and Recreation (CDPR) to develop a

Potential Sites for Establishing New Coastal Dunes
Milkvetch Populations
milkvetch population establishment program at Point Lobos State Reserve. The milkvetch population
establishment program should include the following elements:
■ seed collection strategy to ensure genetic diversity in seeds collected and avoid
overharvesting;
■ seed propagation program for increasing the amount of seed for field dispersal;
■ site evaluation to locate specific sites for seed introduction with appropriate soil,
hydrology, and vegetation characteristics;
■ seed dispersal protocol, including several sowing methods should be tested andcompared
for efficacy; and
■ monitoring and data management program.
DFG should coordinate with CDPR in developing and implementing the milkvetch
establishment program at Point Lobos State Reserve. Other sites should be investigated along the
California coast that are potentially suitable for establishment of coastal dunes milk vetch. The Hearst
Ranch or other sites in coastal San Luis Obispo County may support suitable habitat (Ertter pers.
comm.). Seeds of coastal dunes milk vetch are stored at Rancho Santa Ana Botanical Garden.
Pacific Grove Clover
Description and Taxonomy
Pacific Grove clover is a small annual in the legume family. The stems are semi-prostrate and
2-4 decimeters (dm) long. The palmately compound leaves have three obovate to wedge-shaped
leaflets. Flower petals are light purple with paler tips, 8-10 mm long in small flower heads. Fruits
are two-seeded pods.
Pacific Grove clover has been recognized as a separate species (Munz 1968). The most recent
taxonomic treatment, however, identifies Pacific Grove clover as a phase of whitetip clover (Trifolium
variegatum), a highly variable species (Hickman 1993). Pacific Grove clover is identified in Isely's
treatment of clovers as "phase 4" of whitetip clover and Isely speculates that Pacific Grove clover is
of hybrid origin (Hickman 1993). DFG and CNPS continue to recognize Pacific Grove clover as a
distinct taxonomic entity. The distinguishing characteristic of Pacific Grove clover is its three-toothed
calyx lobes. Flowers of Pacific Grove clover tend to be smaller and paler in color than those of
whitetip clover and the plants are typically smaller overall. Many of the populations of Pacific Grove
clover occur with whitetip clover as well as several other clover species. Pacific Grove clover was
clearly distinguishable from the other clover species at sites where populations were identified in this
study. For the purposes of this report, Pacific Grove clover will be treated as a separate taxonomic

entity. If this clover is confirmed as a hybrid, then the recovery recommendations presented here
would not be applicable.
Listing Status
Pacific Grove clover was a federal Category 1 candidate for listing as threatened or endangered
under the Endangered Species Act (58 FR 188:51144-51190, September 30, 1993); however, U.S.
Fish and Wildlife Service no longer considers Pacific Grove clover to be a candidate for listing as
threatened or endangered because of questions of its taxonomic validity as a species (Rutherford pers.
comm.). Pacific Grove clover was listed as rare under the California Native Plant Protection Act in
September 1979. CNPS considers this species to be rare and endangered in California (List 1B)
(Skinner and Pavlik 1994).
Distribution
Pacific Grove clover is known only from the Monterey and Point Lobos Peninsulas and sites
immediately inland of these areas (Figure 8, Table 3). Before the Jones & Stokes Associates surveys,
Pacific Grove clover had been identified at the following five sites :
■
■
■
■
■
Seventeen Mile Drive near Bird Rock (Site 11) (NDDB 1995),
Indian Village (Site 13) (NDDB 1995),
Asilomar State Beach (Site 5) (Moss pers. comm.),
Monterra Ranch (Site 37) (Yadon pers. comm.), and
September Ranch (Site 51) (Mori pers. comm.).
Six additional occurrences were identified in the Jones & Stokes Associates study at the following
sites:
■
■
■
■
■
■
Spanish Bay Golf Course (Site 7),
Monterey Peninsula Country Club Golf Course (Site 12),
Pebble Beach Equestrian Center parking lot and grandstands (Site 16),
Point Lobos State Reserve on the Moss Cove trail (Site 25),
Lobos Ranch at the south end of Allen Road (Site 32), and
Lobos Ranch at the north end of Allen Road (Site 34).
The occurrence of Pacific Grove clover at Monterra and September Ranches indicates that
it is possible that additional populations of Pacific Grove clover could be found through surveys
focused at inland sites in grassland habitat along the Carmel River Valley and Canyon Del Rey (State
Route 68). The finding of a large number of new populations of this clover along the coast by Jones
& Stokes Associates in 1995 was the result of a focused effort targeted at potentially suitable habitat
on coastal marine terraces.

Ecology and Habitat Requirements
Pacific Grove clover is known from the first, second, third, and fourth marine terraces; recent
(Holocene) dunes in swales; and old (Pleistocene) fluvial terrace. It prefers moist sites such as swales
and wet depressions in coastal prairie and annual grassland habitats. At some sites this clover is the
dominant species over small areas forming a dense carpetlike cover. It has been found on Antioch,
Santa Ynez, and Narlon soils. Pacific Grove clover is tolerant of vegetation disturbance and soil
disturbance. It has been found in pastures, trails, horse training areas, parking areas, picnic grounds,
and abandoned roads and under grandstands. Disturbance regimes where the clover occurs include
horse and pedestrian trampling, vehicle traffic and parking, mowing, and horse and cattle grazing.
During the surveys, Pacific Grove clover was always found in association with other clovers,
including whitetip clover, cow clover (Trifolium wormskioldii), bearded clover (Trifolium
barbigerum), pin-point clover (Trifolium gracilentum), shamrock (Trifolium dubium), and thimble
clover (Trifolium microdon). Cut-leaf plantain, common toad rush (Juncus bufonius), and iris-leaved
rush (Juncus phaeocephalus ) are also typical associates of Pacific Grove clover and indicators of
potentially suitable habitat.
Pacific Grove clover is found mainly (eight of 11 occurrences) associated with grassland
habitat on marine terraces. The two populations found on dunes were in swales that developed in
compacted soils of abandoned roadbeds (Sites 5 and 7). These two populations supported a total of
only about 60 individuals. The one population found on a fluvial terrace by Mori was not surveyed
by Jones & Stokes Associates and supported about 100 individuals (Mori and Morgan pers.
comms.).
Pacific Grove clover flowers from May to June. No pollinators were observed, but small bees
are likely important pollinators.
Reasons for Decline and Threats to Survival
Pacific Grove clover has declined from its historical extent because of residential, golf course,
and other development on the Monterey Peninsula.
Pacific Grove clover occurs on lands owned by the following:

Final Recovery Strategies for Six Coastal Plant Species
on the Monterey Peninsula
May 1996
Approximately 45,000 individuals of Pacific Grove clover were identified at 11 sites in spring
1995 (Table 3). It should be noted that 1995 was a wet year with mild temperatures that produced
large populations of spring wildflowers. Future springs are not likely to produce this many plants
very often. About 2,000 of the Pacific Grove clover plants were in permanently protected sites (Sites
5 and 25) owned by CDPR. Approximately 10,000 plants were at Lobos Ranch (Site 34) in areas
slated to be transferred to CDPR. Although several of the largest populations of Pacific Grove clover
are on private lands that undergo frequent vegetation and ground disturbance (Sites 11, 13, and 16),
the clover has persisted and thrived probably because of the disturbance rather than despite it.
Development at these sites could eliminate these important populations. Populations on grazing lands
at the south end of Allen Road on Lobos Ranch, Monterra Ranch, and September Ranch are not
threatened by the present land use practices; however, development at these sites could eliminate the
populations.
A large number of individuals and several new populations of Pacific Grove clover were found
in 1995. The likelihood for extinction of this species is not considered to be high in the near term.
However, the majority of occurrences and individuals of this clover occur on privately owned land
where land use could change and threaten the species persistence.
Recommendations for Habitat and Population Recovery
Caution should be taken in making attempts to change the existing disturbance regimes at sites
where Pacific Grove clover is presently found because it appears to be persisting and thriving with
the artificial vegetation and ground-disturbing activities at these locations (Sites 11, 12, 13, 16, 32,
37, and 51). The disturbance regimes at these sites are uncontrolled and a gradual transition to
controlled disturbance management is recommended where landowner approval and participation can
be achieved. An example of controlled disturbance management would be the use of grazing livestock
or mowing at a specific intensity and timing, as opposed to uncontrolled recreational use that can vary
greatly in intensity and time of vegetation disturbance.
The occurrences at Asilomar State Beach (Site 5) and Spanish Bay Golf Course (Site 7) are
small populations on marginal habitat (interdune swales created in abandoned roadbeds). These
populations should be monitored but are apparently not important to the species persistence. No
population or habitat enhancement actions are recommended at these sites.
At Seventeen Mile Drive (Site 11), Pacific Grove clover occurs along the horse/pedestrian
trail. This use does not appear to adversely affect the clover, and the vegetation disturbance from
trampling may be of benefit through the reduction of competitive cover. The present recreational use
could continue, but increases in horse or pedestrian traffic (especially horse racing) should be
discouraged.
At the Monterey Peninsula Country Club Golf Course (Site 12), Pacific Grove clover also
occurs in areas of horse and pedestrian traffic and horse jumping. These activities could continue
without threatening the population. Other activities, especially golf course maintenance activities,
could adversely affect this population and should be controlled. Activities such as dumping of lawn
California Department of Fish and Game
GA3079■text
10
Final Recovery Strategies for Six Coastal Plant Species
on the Monterey Peninsula
May 1996
clippings, herbicide spraying or drift, expansion of greens, or other changes in use of these sites
should be discouraged.
At the Indian Village site (Site 13), Pacific Grove clover occurs in areas used for picnicking,
parking, and other activities and adjacent to the volleyball and horseshoes courts. This site is mowed
regularly. A fenced exclosure at this site supports Hickman's cinquefoil (see discussion under the
section "Hickman's Cinquefoil"), but no Pacific Grove clover. The exclosure is not mown and
supports tall grass, likely inhibiting establishment of the clover. Recreational activities and
maintenance mowing at this site could likely continue without threatening the clover population.
However, increases in recreational use or a change in the use of the site could reduce or eliminate the
population. The clover population at this site should be monitored and recreational activities should
be kept to the present type and levels of use. Mowing could continue but should be discontinued
during the flowering and fruiting stages of the clover. Alternatively, mowers could be set to a height
that avoids cutting the low-growing clover flower heads.
At the Pebble Beach Equestrian Center (Site 16), Pacific Grove clover occurs in the parking
and grandstand areas. The heavy ground disturbance in these areas has not kept the clover from
occurring here. Soils in the parking area are compacted Narlon soils with a heavy clay layer (Bt
horizon) starting at 17 inches depth. The soil compaction could favor the clover by creating more wet
areas. Much of the clover habitat at the equestrian center may be of artificial origin and artificially
maintained by heavy disturbance. A large number of plants occur here, roughly estimated at 10,000
individuals. This site could be used for experimental studies of the relationship between the clover
and various vegetation and ground disturbance levels. With landowner cooperation, infrequently used
or unused areas at the equestrian center could be set aside for Pacific Grove clover protection. These
sites could be fenced and managed for an appropriate disturbance regime based on the results of
experimental studies, to favor clover habitat.
The Moss Cove trail occurrence (Site 25) of Pacific Grove clover is within Point Lobos State
Reserve. This population should be monitored. No change in present management practices should
be made unless the population declines. Signs should be placed at the trailhead encouraging hikers
to stay on the trail because of the presence of sensitive species. The specific population location
should be withheld to avoid vandalism.
The occurrences at Lobos Ranch (Sites 32 and 34) are in horse pastures, although the Allen
Road north site (Site 34) apparently has not been grazed in several years. Pacific Grove clover grows
unusually large and tall (about 2 feet tall) among tall vegetation at the Allen Road north site. This site
is also the wettest site on which the clover was found; it has a black soil matrix (N2/0 on the Munsell
color chart), indicating hydric soil conditions. The clover populations at both sites should be monitored
annually and experimental studies of vegetation management techniques, such as various grazing
intensities, should be conducted. The Big Sur Land Trust should bring these two sites under
appropriate management, based on the results of experimental studies, for Pacific Grove clover as
soon as possible. Care should be taken not to overgraze the Allen Road south site (Site 32). The
Allen Road south population (Site 32) is in the proposed Whisler subdivision and could be removed
for development of this project. Impacts on this population should be avoided, if feasible, in the final
design of the project. The conditions at the Allen Road north site are unusual for Pacific Grove clover,
California Department of Fish and Game
GA5079Ven
11
Final Recovery Strategies for Six Coastal Plant Species
on the Monterey Peninsula
May 1996
but grazing should be conducted over portions of the site to test its effect on the clover population.
CDPR should continue management of the Allen Road north population when the land is transferred
to Point Lobos State Reserve.
At the Monterra Ranch (Site 37), the population of Pacific Grove clover was roughly estimated
at 10,000 individuals. The site supports annual grassland grazed by cattle with the clover in natural
wet depressions, drainages, and an old roadbed. This population has been known since 1994 and the
large number of individuals and large area of occurrence of clovers indicates that it has likely been
here much longer. The clover population will likely persist under present land management. With
landowner permission, the population should be monitored and studied. This site offers a good
opportunity to study the effects of different intensities of cattle grazing on clover success. This
privately owned site supports a large area of relatively level or gently sloping terrain and could be
developed, reducing or eliminating the clover population. The largest stand (about 8,000 individuals)
of Pacific Grove clover in the eastern portion of the ranch could be protected through fee acquisition
or conservation easement.
At the September Ranch (Site 52), Pacific Grove clover occurs in areas grazed by cattle and
horses. This occurrence was observed by Mori and Morgan on May 12, 1995, and supports about
100 individuals. This occurrence is on a Pleistocene fluvial terrace (Dupre 1990). The site was not
surveyed by Jones & Stokes Associates and specific soil conditions at the population site have not
been characterized, but the site is mapped as Santa Lucia soil series (U.S. Soil Conservation Service
1978). This site could be developed resulting in the loss or elimination of the population. Not enough
information is available to identify specific management recommendations; however, the general
recommendations provided for the Monterra Ranch site also could be applied here.
Potential suitable habitat for Pacific Grove clover occurs at survey Sites 8, 17, 19, 20, 27, 28,
29, 30, 33, and 38 where populations of clover are not presently known. Of these sites, only Sites 27,
28, 29, and 30 are on public land at Point Lobos State Reserve. These four sites should be considered
for establishment of new populations of Pacific Grove clover (Figure 9). Portions of Site 33 that are
slated to be transferred to CDPR also should be considered for establishment of new populations.
Seed for new population establishment should be collected from the nearest sites supporting Pacific
Grove clover populations, populations from which a natural dispersal would be most likely. Seed
should not be overharvested from existing populations. Clover could be propagated in pots to increase
the amount of seed for field sowing. Pacific Grove clover has been grown successfully from seed in
pots (Ferreira 1995, Yadon pers. comm.). New populations may require some form of artificial
disturbance regime, such as livestock grazing, to maintain the quality of the habitat for Pacific Grove
clover. High-quality habitat for establishment of coastal dunes milkvetch populations should take
precedence over the use of these sites for establishment of new Pacific Grove clover populations
because of the extreme rarity of the milkvetch.

Monterey Clover
Description and Taxonomy
Monterey clover is a small annual in the legume family. Its stems are spreading and 2-4 dm
long. The palmately compound leaves have three wedge-shaped leaflets that are 5-10 mm long. The
flower head has up to 10 pink to lavender, 6-mm-long flowers. The calyx is hairy and 6-7 mm long
with the lobes generally longer than the tube. (Hickman 1993, California Native Plant Society 1994).
Monterey clover is recognized as a separate species (Munz 1968, Hickman 1993). Identifying
characteristics of Monterey clover include the presence of a conspicuous involucre, a long hairy calyx,
and calyx lobes that are long relative to the calyx tube (Hickman 1993). Monterey clover also has
been reported to differ from whitetip and other clovers because it has seven-seeded fruit as opposed
to two-seed fruits (Ferreira 1995). Monterey clover is considered to be most closely related to whitetip
clover and Isely speculates that Monterey clover may be a hybrid of whitetip clover and a noninvolucrate species of clover (Hickman 1993). Monterey clover is distinguished from whitetip clover
by its hairy calyx and smaller, more deeply cut involucre (Hickman 1993).
Listing Status
Monterey clover was proposed for federal listing as endangered under the Endangered Species
Act in August 1995 (60 FR 148:39326-39337, August 2, 1995). It was listed as endangered under
the California Native Plant Protection Act in November 1979 and is also protected as an endangered
species under the California Endangered Species Act. CNPS considers this species to be rare and
endangered in California (List 1B) (Skinner and Pavlik 1994).
Distribution
Monterey clover is known only from the central portion of the Monterey Peninsula (Figures
10 and 11). Before the 1987 fire at Huckleberry Hill, Monterey clover was known only from
occurrences at the S.F.B. Morse Botanical Reserve and near State Route 68 (Yadon pers. comm.)
(Figure 10). In spring 1988, much larger populations were identified along Costanilla Way and Los
Altos Road and in the S.F.B. Morse Botanical Reserve (Yadon pers. comm.) (Figure 10). A small
number of plants were observed near State Route 68 following a fire in 1990 (Yadon pers. comm.)
(Figure 10). Jones & Stokes Associates surveys in 1995 identified two occurrences of Monterey
clover with a total of 22 plants along Costanilla Way (Sites 42 and 44) (Figure 11, Table 4).
Ecology and Habitat Requirements
Monterey clover occurs on the fifth and sixth marine terraces and the intervening slope
between these terraces. The largest populations observed in 1988 were on the sixth marine terrace

Figure 11
Known Distribution of Monterey Clover in 1995
(Figure 10). Populations observed in 1995 were on the sixth terrace on Narlon and Huckleberry soils.
Huckleberry soils are a variant of the Narlon series with bright red mottles in the Bt horizon (Jones &
Stokes Associates 1994a). These soils support a thin or no A horizon, a leached E horizon, and a Bt
horizon of massive, compacted sandy clay at 10-12 inches depth. Water accumulates on the clay
layer.
Monterey clover is a fire follower, only appearing in large numbers after fire has removed the
vegetative cover. It occurs in greatest numbers in the spring following crown fires in Monterey pine
forest and pygmy forest dominated by a mix of Bishop pine (Pinus muricata) and Gowen cypress.
A large fire in May 1987 burned stands of Monterey pine and pygmy forests on the fifth and six
marine terraces and intervening slopes at the S. F. B. Morse Botanical Reserve and Huckleberry Hill
Natural Area. Monterey clover appeared the following spring in large numbers on the sixth terrace
(Sites 41 and 43) in recovering Monterey pine forest and in smaller numbers at scattered locations on
the fifth terrace (Site 49) in recovering pygmy forest and on intervening slopes (Sites 51 and 45) in
recovering Monterey pine forest. Following a fire in 1990, a few individuals of Monterey clover were
found south of State Route 68 in recovering Monterey pine forest on the fifth terrace (Sites 46 and 47)
(Yadon pers. comm.).
As forests recover, the dense stands of pine and cypress seedlings and recovering shrubs shade
and crowd Monterey clover, and the clover populations decline rapidly. In spring 1989, only a few
Monterey clover plants could be found at the sites of 1988 occurrences, with much of the previous
year's clover habitat dominated by foothill deer vetch (Lotus humistratus) (Yadon pers. comm.). All
sites known to support Monterey clover during the 1980s and 1990s were surveyed in 1995 and only
two occurrences were found in small grassy clearings. Where approximately 1,000 individuals were
estimated to occur in 1988, only 22 individuals were found in 1995.
Woody species most often associated with Monterey clover are Monterey pine (Pinus radiata),
Hooker's manzanita (Arctostaphylos hookeri var. hookeri), shaggy-barked manzanita (Arctostaphylos
tomentosa), and huckleberry (Vaccinium ovatum). Where Monterey clover occurs in pygmy forest,
it is associated with Bishop pine and Gowen cypress. Herbaceous species often associated with
Monterey clover are wild oats (Avena spp.), annual fescues (Vulpia spp.), Australian fire weed
(Erechtites argula), and thimble clover.
Monterey clover flowers from April to June. No pollinators were observed, but small bees are
likely important pollinators as they are with other clovers.
In summary, Monterey clover regenerates from seed following fires in Monterey pine and
pygmy forest. It appears to prefer Huckleberry and Narlon soils on the fifth and six marine terraces
and intervening slopes. The clover appears to be most strongly associated with Monterey pine forests
on the sixth terrace (Figure 10). By the second year of vegetation recovery following a burn event,
clover populations decline rapidly. Small populations may persist for several years in clearings, but
these will likely disappear with closure of the forest canopy. Scattered individuals may persist or
occur periodically at disturbed sites, such as fire roads, as recorded in the pygmy forest prior to the
1987 fire (Natural Diversity Data Base 1995) (Figure 10). Monterey clover is obviously dependent
on long-term seed dormancy for survival. It is not known what factor(s) cause the release of seeds
California Department of Fish and Game
G.VKITAkst
14
Final Recovery Strategies for Six Coastal Plant Species
on the Monterey Peninsula
May 1996
from dormancy; possible factors are light, soil nutrient pulse following fire, and destruction of
germination-inhibiting compounds by heat.
Reasons for Decline and Threats to Survival
The historical extent of Monterey clover is not known. Based on its association with the fifth
and sixth marine terraces, the loss of potential habitat from residential and golf course development
on the Monterey Peninsula has been about 69%, from a historical extent of 1,754 acres to a present
extent of 539 acres (estimated using data from Jones & Stokes Associates 1994b). Fire suppression
prevents Monterey clover from germinating and producing new generations. The seed bank would
be expected to decline over time as seeds age and succumb to disease.
Residential development is proposed by the Pebble Beach Company (Subdivision #6, Area
G) for a portion of the largest known historical occurrence of Monterey clover between Costanilla Way
and Haul Road (EIP Associates 1995). This occurrence of clover was estimated to support 1,000
individuals in spring 1988 (Yadon pers. comm). The subdivision plan includes open space areas that
would provide protection for portions of Monterey clover habitat. As proposed, this development
would result in the removal of nine Monterey clover plants identified in 1995 next to the fire road at
Site 42.
A 150-foot wide fuelbreak, proposed for the west side of Costanilla Way and Los Altos Drive
could result in the loss of one clover occurrence (Site 44) and potentially adversely affect the clover
seed bank. The fuelbreak project was initiated in 1995 with Monterey pine trees removed to thin the
stand, lower limbs removed from remaining trees to reduce the fuel ladder, and groundcover cut to
a height of 18-36 inches. The fuelbreak project, however, could offer an opportunity for Monterey
clover management (see "Recommendations for Habitat and Population Recovery").
Many of the past occurrences and a soil seed bank of the clover are in the Huckleberry Hill
Natural Area, owned by the Pebble Beach Company, and the S.F.B. Morse Botanical Reserve, owned
by the Del Monte Forest Foundation. One occurrence of Monterey clover recorded in 1980 is
presumed to have been extirpated as a result of the development of Poppy Hills Golf Course in 1980
(60 FR 148: 39326-39337, August 2, 1995).
Recommendations for Habitat and Population Recovery
Fire is the pivotal factor in the ecology of Monterey clover. However, because development
surrounds the known occupied habitat of Monterey clover, the use of fire for habitat management only
should be considered in light of appropriate measures to avoid an unacceptable risk to life and
property. Lower risk methods of burning to create clover habitat could be used. For example,
Monterey pine forest could be cut and chipped or cleared and ground fires set, within areas confined
by fire roads, to open habitat for clover. The appropriate seasonal timing of burns for maximum
reproduction of Monterey clover should be investigated and the results incorporated into the fire

on the Monterey Peninsula

management action. Any use of controlled burning, however, involves the risk of escape and may be
determined to be an unacceptable action by local or state agencies or the public.
Germination requirements for Monterey clover needs to be studied. Clover seed should be
collected for research purposes from natural populations in spring 1996 and from private or publicly
held material. If Monterey clover seeds are found to respond to cues other than fire, it may be
possible to develop habitat management techniques that do not require fire as a management tool and
therefore avoid the risks of fire use near developed areas. Monterey clover has been grown
successfully from seed in pots without the use of heat treatment (Yadon pers. comm.).
Sites supporting potential suitable habitat for Monterey clover could be used to establish new
populations. Some of these sites may support Monterey clover seed in the seed bank. Sites
supporting large stands of Monterey pine forest on the fifth or sixth marine terrace include portions
of the following:
■ Pescadero Tract;
■ Huckleberry Hill Preserve at the Presidio of Monterey; and
■ Gibson Creek unit of Point Lobos State Reserve, including sites with pygmy forest and
Monterey pine forest (Figure 12).
Controlled fire could potentially be used at the Gibson Creek site because of its more isolated
location and public ownership. Management at the Gibson Creek site should combine clover habitat
creation and management with Gowen cypress habitat management (see discussion of Gowen cypress
in this report).
Although Monterey clover has not been observed on the fourth marine terrace, the fourth
marine terrace supports soils, Monterey pine forest, and understory vegetation with many similarities
to the fifth and sixth terraces (Jones & Stokes Associates 1994a). A large stand of Monterey pine
forest remains on the fourth terrace on Santa Ynez soils at the Monterra Ranch (Figure 12). If the
landowner is amenable, test manipulations of habitat and introductions of Monterey clover could be
conducted at the ranch. Because of its inland location, different soil characteristics, or other features,
this site may prove to be unsuitable for Monterey clover. However, if the site proves viable as clover
habitat, its isolation from development makes the use of fire for management potentially more
acceptable at this site than at other sites discussed above. Development is proposed for the Monterra
Ranch. Land acquisition, conservation easements, or other methods could be used to protect sites of
newly established populations of Monterey clover at Monterra Ranch and these areas could be
connected to conservation areas for known populations of Pacific Grove clover. Proposed
development at Monterra Ranch is expected to include set-aside areas for habitat.
The proposed 150-wide fuelbreak along the west side of Costanilla Way and Los Altos Drive
provides an opportunity to manage the Monterey clover habitat. The fuelbreak location includes areas
of past and present occurrences of clover and is entirely within areas of potentially suitable clover
habitat. Various vegetation manipulation methods and seed sowing techniques should be tested within
California Department of Fish and Game
GA5079'vext

on the Monterey Peninsula

the fuelbreak site. Successful establishment and management methods should then be incorporated
into the overall management of the fuelbreak. The fuelbreak site should be monitored each spring for
occurrences of Monterey clover.
The largest known past and present occurrences of Monterey clover are in the Monterey pine
forest site between Haul Road and Costanilla Way (see survey Site 43 on Figure 4 ). Portions of this
area are proposed for development by Pebble Beach Company. This site should be protected to
preserve what is likely the largest seed bank of the clover. Although the use of fire as a management
tool may not be acceptable at this site, other vegetation management techniques that create openings
suitable for Monterey clover germination should be tested on a small scale. Manipulation of habitat
at this site should be kept to a minimum until more is known about the ecology of Monterey clover
and new clover populations have been successfully established at other sites. Because of its
importance to the survival of the species, efforts should be made to bring this site into permanent
protective status.
Research on the germination requirements and management methods for Monterey clover is
needed. Ecological requirements and management techniques that should be investigated include
identifying:
■ the seasonal timing of fire that results in the greatest Monterey clover regeneration
response;
■ spot-burning techniques that could be used in Monterey clover habitat where larger
controlled fires may not be feasible; and
■ nonfire vegetation management, such as canopy clearing and mowing, that results in
regeneration of Monterey clover.
Hickman's Cinquefoil
Description and Taxonomy
Hickman's cinquefoil is a perennial herb in the rose family (Rosaceae). Stems are prostrate
to decumbent and more or less glabrous. The leaves form a rosette from a thick, woody taproot. The
leaves are pinnately compound and 4-30 cm long, with four to seven pairs of leaflets. Leaflets are
palmately cleft. Inflorescences generally have fewer than 10 flowers. Petals are yellow and
are 6-10 mm long. The hypanthium is usually 3-6 mm wide. Achenes are 2 mm long and glabrous.
(Hickman 1993, California Native Plant Society 1987.)
Distinguishing characteristics of Hickman's cinquefoil include slender styles 2-3 mm long that
are attached near the tip of the ovary; four to seven pairs of leaflets, each divided midway to the base;
and subglabrous herbage.

Listing Status
Hickman's cinquefoil was proposed for federal listing as endangered under the Endangered
Species Act in August 1995 (60 FR 148:39326-39337, August 2, 1995). It was listed as endangered
under the California Native Plant Protection Act in September 1979 and is also protected as an
endangered species under the California Endangered Species Act. CNPS considers this species to be
rare and endangered in California (List 1B) (Skinner and Pavlik 1994).
Distribution
Hickman's cinquefoil is known from two occurrences, the Indian Village site (Site 13) on the
Monterey Peninsula (Figure 13) and an occurrence recently discovered by the California Department
of Transportation (Caltrans) on a Caltrans study corridor near Devil's Slide in San Mateo County
(Vonarb and Ertter pers. comms.). The Indian Village occurrence supported approximately 14 plants
in 1995; however, another survey by University of California, Berkeley, botanists identified 21 plants
at the Indian Village site in 1995 (Morosco pers. comm.). A May 1992 survey of this site found 24
plants present (Ferreira 1995).
The number of plants at the Devil's Slide site was estimated to be 2,600 divided among three
subpopulations (Vonarb pers. comm.). This recent discovery near Devil's Slide opens up the
possibility that other populations of Hickman's cinquefoil may be found along the central California
coast (Ertter pers. comm.).
An occurrence of Hickman's cinquefoil, was reported by Suttliffe in 1933 from a flat
overlooking the ocean 0.7 mile south of Montara Point near Moss Beach in San Mateo County
(Natural Diversity Data Base 1995) and this occurrence could be the one found in 1995 by Caltrans.
An occurrence reported by Crum in 1932 from Pacific Grove near the reservoir has also been
extirpated by development (Ferreira 1995).
Ecology and Habitat Requirements
At Indian Village, Hickman's cinquefoil occurs in a grassy opening in Monterey pine forest.
Although Duprë (1990) maps this site as Pleistocene dunes covering the second marine terrace, the
Indian Village site is actually an exposed portion of second terrace with Santa Ynez soils. These soils
support an A horizon of sand and organic material, a leached E horizon at 5-inch depth, and a clay Bt
horizon at 10-inch depth. Surrounding areas appear to contribute drainage to the site and the clay
layer ponds water, resulting in wet meadow conditions where the cinquefoil grows. Adjacent habitat
is closed-canopy Monterey pine forest on old dunes with deep, sandy Tangair soils that do not support
Hickman's cinquefoil.
At Indian Village, 13 of the 14 Hickman's cinquefoil plants occur within a fenced exclosure,
with no vegetation management. The exclosure is dominated by soft chess, slender oats (Avena
barbata), annual fescues, and wild barley (Hordeum murinum ssp. leporinum). Other associates

include California oatgrass, coast gumplant (Grindelia latifolia), ripgut brome (Bromus diandrus),
little rattlesnake grass (Briza minor), common geranium (Geranium dissectum), and curly dock
(Rumex crispus). Hickman's cinquefoil is surviving within the dense competitive grassland inside
the exclosure, but could succumb to the competition without some management of the site to reduce
vegetative cover. Scattered individuals of cinquefoil occur outside the exclosure; only one was found
in 1995, in the heavily used recreational areas. Hickman's cinquefoil appears less tolerant of
vegetation and soil disturbance from trampling, grazing, and mowing than Pacific Grove clover, which
thrives in the recreation area. In 1992, nine cinquefoil plants were found inside the exclosure and 15
were found outside the exclosure (Ferreira 1995). An intermediate level of vegetation disturbance
(e.g., ground fire, grazing, or mowing) may be beneficial to Hickman's cinquefoil by reducing
competition without resulting in high cinquefoil mortality.
At the Devil's Slide site, Hickman's cinquefoil occurs in level to sloping grasslands. The site
has been grazed, and Hickman's cinquefoil is associated with native needlegrasses (Nassella spp.) and
California oatgrass and non-native canary grass (Phalaris sp.). The cinquefoil appears to grow best
with the native grasses on level to gently sloping mesic sites. (Vonarb and Ertter pers. comms.).
A single plant collected from the field at Indian Village flowered and set seed in its pot, and
the seed produced viable offspring in the absence of cross pollination, indicating that the species is
likely self-compatible or apomictic (Yadon pers. comm.). Hickman's cinquefoil has protogynous
flowers, the stigma is receptive to pollen before the pollen-bearing anthers open within the same
flower; this timing mechanism tends to reduce self-fertilization and increase the potential for
outcrossing.
No pollinators were observed, but based on the open floral structure, Hickman's cinquefoil is
likely pollinated by a wide variety of flies, bees, and beetles. Hickman's cinquefoil produces seed late
in the season and dry years may result in low or no seed production (Yadon pers. comm.).
Reasons for Decline and Threats to Survival
Hickman's cinquefoil has declined as a result of coastal development (Ferreira 1995). The
Indian Village population is threatened by proposed development of surrounding land that could
adversely affect the hydrology of the Indian Village site and possibly by competition from grasses
inside the exclosure. If vegetative cover within the exclosure is not reduced, the population of
cinquefoil may succumb to competition from tall grasses. Mowing and heavy recreational use of
areas of suitable habitat surrounding the exclosure appears to be preventing the Hickman's cinquefoil
population from successfully expanding into areas outside the exclosure. Uses at the Indian Village
site include parking lots, picnic areas, a volleyball court, and horseshoes courts.
At Indian Village, herbivory by deer and gophers may reduce survivorship and reproduction
of Hickman's cinquefoil. Gopher activity, however, could improve habitat for the cinquefoil by
removing competing vegetation (Yadon pers. comm.). Changes in local drainage at Indian Village
as a result of proposed development on adjacent parcels could adversely affect the cinquefoil habitat
(Matthews pers. comm.). Competition from the non-native perennial kikuyu grass (Pennisetum

clandestinum) may threaten the Indian Village cinquefoil population if this grass is not controlled
(Yadon pers. comm.).
The population of Hickman's cinquefoil near Devil's Slide may be affected by Caltrans'
proposed State Route 1 bypass and by potential development of the private land on which it occurs.
The Indian Village population of Hickman's cinquefoil is on property owned by the Del Monte
Forest foundation. The population near Devil's Slide is on privately owned land next to a state park,
but no plants have been found in the park (Vonarb pers. comm.).
Recommendations for Habitat and Population Recovery
Both occurrences of Hickman's cinquefoil are on private property and are threatened by the
present use or potential future uses of those properties.
At Indian Village, available habitat for cinquefoil could be expanded through some or all of
the recreational activities being moved to another site or consolidated to a smaller area at the Indian
Village site. In summer 1995, Pebble Beach Company moved the volleyball and horseshoe courts,
horse tie-up facilities, and log barriers to the west side of the Indian Village site and rocks were placed
to discourage vehicle traffic (Staub pers. comm.). About five group events per month, such as
volleyball games and horseshoe competitions, take place at the site. If recreational uses are controlled
, grassland habitat should recover on the site and Hickman's cinquefoil would likely become
established in these areas without artificial assistance. All designated cinquefoil habitat at the site
should be fenced to discourage pedestrian and horse traffic. The grassland should be managed to
prevent grasses from outcompeting the cinquefoil and to keep Monterey pine from establishing and
creating excessive shade. An adaptive management program should be applied, with testing of light
mowing or grazing as possible vegetation management techniques.
The following steps are recommended for more rapidly increasing the number of Hickman's
cinquefoil plants, rather than waiting for natural population expansion, at Indian Village Site:
■ Develop greenhouse techniques for amplifying seed using material from the Devil's Slide
populations.
■ Apply successful seed amplification methods to Indian Village material.
■ Bring Hickman's cinquefoil into successful cultivation, maintaining strict records on the
origin of material.
■ Expand the number of plants at Indian Village by outplanting cultivated material
originating from Indian Village seed source.
The University of California, Berkeley, has collected about 150 seeds from the Devil's Slide
population that could be used in testing seed amplification methods (Enter pers. comm.).
California Department of Fish and Game

Mav 1996
Techniques for enhancing Hickman's cinquefoil survival and reproduction should be tested.
Plants presently in cultivation by the Pebble Beach Company (about 20 plants) and Vern Yadon (about
10 plants, all offspring from single parent) should be used to test these techniques.
Techniques to be tested on potted or outplanted individuals should include:
■ caging to reduce herbivory,
■ weeding around plants to reduce competition, and
■ supplemental watering to extend fruiting period.
With landowner cooperation, the Devil's Slide occurrence should be studied to further
elucidate the habitat requirements of Hickman's cinquefoil and effective population and habitat
enhancement techniques. The larger, more isolated condition of this site and much larger number of
plants makes it a more readily recoverable location than Indian Village for Hickman's cinquefoil. The
possibility of acquiring this site, and entering into a conservation easement or other method to protect
the population in perpetuity should be investigated with the landowner by DFG.
One site with potentially suitable habitat for establishment of a new population of Hickman's
cinquefoil was identified in the Jones & Stokes Associates 1995 surveys. This site is at Lobos Ranch
(Site 34) at the Allen Road north occurrence of Pacific Grove clover (Figure 14). Because it is on the
second marine terrace and supports wet meadow habitat on Santa Ynez soils, the site is similar to
Indian Village. The suitability of the site or adjacent areas for cinquefoil introduction should be
investigated. This land belongs to the Big Sur Land Trust and is slated to be transferred to CDPR.
Hickman's cinquefoil, originating from the Indian Village population, is being grown successfully by
the Pebble Beach Company and Vern Yadon and seed from these plants could be used to propagate
new populations. Additional seed from the Indian Village population also could be collected,
amplified, and used to establish plants at Site 34.
, Efforts should be made to locate undiscovered occurrences of Hickman's cinquefoil. With
the use of existing geology and soils maps and knowledge of the typical characteristics of Hickman's
cinquefoil habitat, these surveys could be narrowly focused on targeted sites with the highest
probability of cinquefoil occurrence. The discovery of new occurrences, especially if some are on
public lands, would provide greater flexibility to recovery actions and a greater likelihood for recovery
success.
Genetic studies of Hickman's cinquefoil are needed to better understand the relationship
between the Indian Village and Devil's slide populations. It is possible that these populations are
genetically distinct because of their wide geographic separation. Although the Indian Village
population is small, if it is genetically distinct from the Devil's Slide population, then it is genetically
important to the species. Material from the two populations should be kept separate.

Potential Site for Establishing New
Hickman's Cinquefoil Populations
Yadon's Rein Orchid
Description and Taxonomy
Yadon's rein orchid is a perennial herb in the orchid family (Orchidaceae) that has been
recently described as a species (Morgan and Ackerman 1990). The bulb-like caudex produces one
to two basal leaves 10-15 cm long and 2-3.5 cm wide. Plants grow for several years before producing
flowering stalks. The single flowering stalk can reach 80 cm tall in height. The upper sepal is green
with white margins and the lower sepals are white. Lateral petals are green with white margins and
the lower petal (lip) is white. The spur is white, 2.5-4 mm long, and pointed downward. The fruit
is a capsule with many minute seeds. (Hickman 1993; 60 FR 148:39326-39337, August 2, 1995.)
Yadon's rein orchid is distinguished from other rein orchids (Piperia spp.) by its short spur,
white margins on upper sepals and petals, white lower sepals and petals, and cylindric rather than onesided inflorescence (Hickman 1993).
Listing Status
Yadon's rein orchid was proposed for federal listing as endangered under the Endangered
Species Act in August 1995 (60 FR 148:39326-39337, August 2, 1995). It is not listed as threatened
or endangered under the California Endangered Species Act. CNPS considers this species to be rare
and endangered in California (List 1B) (Skinner and Pavlik 1994).
Distribution
The known distribution of Yadon's rein orchid is shown in Figure 15. The largest number of
occurrences of Yadon's rein orchid are known from the Monterey Peninsula (Figure 15). It occurs
in undeveloped areas throughout the Peninsula. Inland of the Monterey Peninsula, four small
occurrences are known from along Jack's Peak Road and Garden Road (Figure 15). Four occurrences
are known from sites to the north at The Nature Conservancy's (TNC's) Blohm Ranch Preserve,
Tucker Road, Manzanita Regional Park, and Vierra Canyon (Figure 15). Population size estimates
for these four occurrences are based on flowering stalk counts and do not include plants in vegetative
state; therefore, underestimates of population sizes are likely. In surveys conducted between 1990 and
1995, approximately 56,000 individuals of Yadon's rein orchid have been counted at all known
occurrences with about 96% of these plants on the Monterey Peninsula (Allen pers. comm., Natural
Diversity Data Base 1995, this study). Surveys for Yadon's rein orchid conducted by Pebble Beach
Company in February-March 1995 before the flowering period depended on leaf characteristics to
identify rein orchids and used known habitat and distribution requirements to separate Yadon's rein
orchid from Michael's rein orchid (Piperia michaelii) (Allen pers. comm.). Because leaves of these
two species cannot be readily distinguished, the amount of Yadon's rein orchid may have been
overestimated through counting of Michael's rein orchid plants. The southernmost occurrence of

Known Distribution of Yadon's Rein Orchid
MI
Yadon's rein orchid was found by Jeff Norman in 1995 at Palo Colorado Canyon and supported
approximately 38 individuals (Figure 15) (Morgan pers. comm.).
An occurrence reported near State Route 1 at Fort Ord in 1992 (U.S. Army Corps of Engineers
1992) was not relocated during Jones & Stokes Associates' surveys in 1995. Approximately six
Yadon's rein orchid individuals were found at this site in 1991, but the orchid was not found in
surveys conducted in 1993 and 1994 (Morgan pers. comm.).
Ecology and Habitat Requirements
Yadon's rein orchid occurs in Monterey pine forest, maritime chaparral, and pygmy forest
habitats. In Monterey pine forest, Yadon's rein orchid typically grows in openings with grassy
understory cover. It does not occur where shrub cover is dense or in densely vegetated drainages
(Allen pers. comm.). In maritime chaparral, the rein orchid typically occurs under low shrubs,
particularly Hooker's manzanita (A rctostaphylos hookeri var. hookeri), which serves as an indicator
species of rein orchid habitat (Allen pers. comm.). In early summer, the orchid's inflorescence
emerges from the shrub canopy. Yadon's rein orchid appears to be of smaller stature in chaparral than
in Monterey pine forest.
Yadon's rein orchid occurs on a variety of soil types and geomorphic surfaces. The largest
populations occur on the third through sixth marine terraces and intervening granitic slopes, with
smaller populations occurring on the second marine terrace and Pleistocene dune deposits. Most
occurrences of Yadon's rein orchid appear to be on Narlon and Huckleberry soils.
The rein orchid appears to thrive in partial shade and apparently is not tolerant of sustained
high soil moisture (Allen pers. comm.). Yadon's rein orchid is sometimes found invading fresh road
cuts (Allen pers. comm.). Individual plants may need to reach a certain age or bulb size before they
will flower and set seed. Flowering occurs from May through August. No observations of pollinators
have been made. Seeds are minute and wind dispersed. Strong winds are likely to carry the millions
of dust-like seeds produced by a large population over a large area. Typical of orchids, the roots of
Yadon's rein orchid form a close symbiotic association with mycorrhizal fungi. This relationship is
referred to as "mutualism". The orchid requires the fungus and the fungus requires the orchid.
Deer browsing on stalks and leaves of Yadon's rein orchid appears to be an important factor
in mortality and reproduction. A preliminary study of caged orchid plants indicated that 2% of plants
produce flowering stalks outside the cages, where they are subject to deer browsing, and
approximately 80% of plants protected inside cages produce flowering stalks (Allen pers. comm.).
Reasons for Decline and Threats to Survival
Yadon's rein orchid populations have been extirpated from portions of the Monterey
Peninsula; many historical collections have been made in the Pacific Grove area (60 FR 148:3932639337, August 2, 1995). Urban and recreational development of the peninsula have resulted in a
California Department of Fish and Game
GA5079 \ rer4
23
Final Recovery Strategies for Six Coastal Plant Species
on the Monterey Peninsula
May 1996
decline in rein orchid populations, and continued urban and golf course developments threaten
remaining populations. Browsing by the large population of deer on the peninsula threatens orchid
reproduction. Other threats to Yadon's rein orchid include competition from non-native plants,
roadside vegetation maintenance, and a proposed realignment of U.S. Route 101 near Prunedale (60
FR 148:39326-39337, August 2, 1995).
Yadon's rein orchid occurs on property owned by public and private entities including the
Pebble Beach Company, Del Monte Forest Foundation, U.S. Department of Defense, County of
Monterey, and TNC. The largest number of occurrences and individuals (approximately 50,000) are
on Pebble Beach Company property (Allen pers. comm.). Yadon's rein orchid is afforded some
protection through land use designations at the S. F. B. Morse Botanical Reserve, Huckleberry Hill
Natural Area, Huckleberry Hill Preserve, George Washington Park, Crocker Cypress Grove, Veterans
Memorial Park, Manzanita County Park, and the Blohm Ranch Preserve. These areas support
approximately 9,600 plants, or about 17% of the total known number of individuals.
The large numbers of Yadon's rein orchid recently identified, particularly by studies conducted
by the Pebble Beach Company in February-March 1995, indicate that this species is not as uncommon
as previously believed. Before these studies, the total number of rein orchid individuals was thought
to be fewer than 2,000 individuals (Natural Diversity Data Base 1995). As discussed above, the total
known population is now estimated at 56,000 individuals. This large number of plants, however, is
concentrated into small areas mostly on private property and many are at sites proposed for
development projects.
Recommendations for Habitat and Population Recovery
For the purpose of this discussion, occurrences of Yadon's rein orchid were grouped into
seven locations that support large numbers of plants:
■ S. F. B. Morse Botanical Reserve and Huckleberry Hill Natural Area (7,600 plants, 13.5%
of individuals);
■ Pescadero Tract (15,700 plants, 28% of individuals);
■ sites to the north of the Pebble Beach Riding Stables along Drake Road, Stevenson Drive,
Forest Lake Road, and Bristol Curve (14,600 plants, 26% of individuals);
■ sites along Stevenson Drive and Forest Lake Road surrounded by Spy Glass Hill and
Poppy Hills Golf Courses (8,500 plants, 15% of individuals);
■ sites along Spruance, Ronda, and Sunridge Roads (2,400 plants, 4% of individuals);
■ Old Capitol Site (2,500 plants, 4% of individuals); and
■ Blohm Ranch Preserve (2,000 plants, 3.5% of individuals).
California Department of Fish and Game
GA5070,kw
24
Final Recovery Strategies for Six Coastal Plant Species

May 1996
These seven sites combined support approximately 94% of the known individuals of Yadon's
rein orchid (Figure 15). In this section, population size and status are described and management
recommendations provided for each of these seven sites; recommendations are provided for overall
habitat and population management and recovery of the species; and locations for additional surveys
are recommended.
Recommendations for Management and Recovery by Location. Yadon's rein orchid
occurrences at the S. F. B. Morse Botanical Reserve and Huckleberry Hill Natural Area receive some
level of protection from future development because these areas have been designated as open space
by the Del Monte Forest Foundation and Pebble Beach Company. Approximately 7,600 plants, about
13.5% of the known individuals, were found in this area in 1995 (Allen pers. comm.). The
populations in this area may have increased since 1987, when fire removed the pygmy forest cover
of dense trees and shrubs. The recovering pygmy forest supports much more open vegetation than
a mature pygmy forest and therefore more habitat for the rein orchid. Hooker's manzanita, an
indicator of orchid habitat, is common in the recently burned areas but not in the mature forest. It is
likely that suitable habitat for Yadon's rein orchid will decline over time as the pygmy forest recovers
and matures, providing less open vegetation. Management of the forest to maintain areas of open
habitat for the orchid should be conducted. The use of fire as a management tool at this site is not
feasible because of the risk it poses to surrounding residential areas, and other techniques for
maintaining forest openings should be studied. The rein orchid occurrences at these reserves are
important to the long-term protection and recovery of the species because the sites are already in
protected status, the extent of natural vegetation here is large and can be managed efficiently, and this
is the only known occurrence of rein orchid in pygmy forest habitat.
Pescadero Tract is owned by the Pebble Beach Company and supports approximately 15,700
Yadon's rein orchid plants, about 28% of the known individuals The orchids occur within a large area
of natural Monterey pine forest. This site has been proposed for golf course development but if the
landowner were to agree to protect this population of Yadon's rein orchid, the site could serve as a
valuable location to ensure the long-term viability of the species.
North of the Pebble Beach Equestrian Center large populations of rein orchid, approximately
14,600 plants (about 26% of the known individuals), are supported along Drake Road, Stevenson
Drive, Forest Lake Road, and Bristol Curve. These sites support stands of Monterey pine forest with
grassy understory vegetation. All of these sites are proposed for residential development by the Pebble
Beach Company. If the landowner were to agree to protect these populations, it could serve as a
valuable location to ensure the long-term viability of the species.
Scattered large populations of Yadon's rein orchid occur along Stevenson Drive and Forest
Lake Road surrounded by Spy Glass Hill and Poppy Hills Golf Courses and residential development
on land owned by the Pebble Beach Company. Approximately 8,500 plants, about 15% of the total
known individuals, occur at these sites. These sites are fragmented by existing residential and golf
course development and proposed new development would add to that fragmentation. The fragmented
nature of these sites makes them difficult to manage and prone to local extinctions. These sites are
not recommended for long-term management or recovery of the species, but loss of plants and
fragmentation of populations should be avoided or minimized if these sites are developed.

Scattered large populations of rein orchid occur along Spruance, Ronda, and Sunridge Roads
in Monterey pine forest surrounded by residential development. These sites support about 2,400
plants, about 4% of the known individuals. These sites are proposed for development by the Pebble
Beach Company. The loss of plants should be avoided or minimized if these sites are developed.
The Old Capitol Site is owned by the Pebble Beach Company and supports approximately
2,500 Yadon's rein orchid plants, about 4% of the known individuals. This site has been proposed for
development. The loss of plants should be avoided or minimized if these sites are developed.
The Blohm Ranch Preserve is managed as a nature preserve by TNC. At this site, the rein
orchid occurs at three locations with Hooker's manzanita in maritime chaparral. This occurrence is
the largest of the four northern populations with about 2,000 plants, about 3.5% of the known
individuals and Yadon's rein orchid is expected to persist under proper management by TNC at this
site.
Recommendations for Species Management and Recovery
The focus of protection and recovery of this species should be through protection and
management of existing populations because large populations remain within areas of native
vegetation. Yadon's rein orchid bulbs have been successfully transplanted at the Old Capitol Site
(Allen pers. comm.) but the long-term viability of these plants has not been monitored. Because of
the mycorrhizal fungus-orchid mutualism, native soil with fungal spores would need to be used in any
programs developed to grow or transplant the orchid. Although establishment of new orchid
populations may be feasible, it is a less certain approach than working to maintain and enhance the
existing natural populations. Tht key to maintaining suitable habitat is to manage Monterey pine
forest for an open canopy and grassy understory and pygmy forest for early successional chaparral.
If ecotypic variation exists within the species, it is likely to be greatest among different habitats
and at the fringes of the distribution. Populations of Yadon's rein orchid should be protected in each
of the three habitats from which it is known, Monterey pine forest, pygmy forest, and maritime
chaparral. Populations at the extremes of the range should also be given priority. Important
populations at the fringe of the distribution are the Blohm Ranch Preserve population, the four
populations along Jack's Peak Road and Garden Road, and the population at Palo Colorado Canyon
(Figure 15).
Sites of large rein orchid populations with some existing protected status should be managed
to maintain populations within specific size ranges. These sites are the Huckleberry Hill Natural Area,
S. F. B. Morse Reserve, Blohm Ranch Preserve, and Manzanita County Park. DFG should coordinate
with Del Monte Forest Foundation, TNC, and Monterey County to establish management and
monitoring programs for Yadon's rein orchid on these properties. These sites support at total of
approximately 9,600 plants, or about 17% of the known individuals. Population sizes are expected
to fluctuate annually. Because this species can remain dormant during years with poor conditions,
it may not appear every year even though bulbs are present in the ground. For example, at Blohm
Ranch Preserve for example, a site that supported a population of approximately 1,000 plants in 1995
California Department of Fish and Game
GAS079Yert
26
Final Recovery Strategies for Six Coastal Plant Species
on the Monterey Peninsula
May 1996
apparently did not support any plants in 1994 (Zembsch pers. comm.). Population sizes at each site
should be monitored to determine whether they are stable, declining, or increasing. An adaptive
management approach should be used to address declining populations.
The five large concentrations of Yadon's rein orchid on private property slated for
development by the Pebble Beach Company support about 77% of the known individuals of Yadon's
rein orchid. The Pescadero Tract and the site north of the Pebble Beach Equestrian Center are the
largest and least fragmented of these occurrences. These two sites account for about 54% of the
known individuals of Yadon's rein orchid. Efforts to protect the species should be focused on these
two sites. At the other three sites, the loss of rein orchid habitat and populations should be avoided
or minimized if development proceeds. The Pebble Beach Company should be approached by DFG
and U.S. Fish and Wildlife Service to identify how rein orchid protection and management could be
integrated into development plants for these sites.
The combined protection of Yadon's rein orchid at existing protected sites and the two largest
unprotected sites would result in retention of at least 70% of the known individuals of the species
within larger areas of native plant communities. Portions of other occurrences at sites planned for
development could also persist with implementation of appropriate mitigation measures during
development. Retention of more than 39,000 plants within four large population centers would likely
be sufficient to ensure long-term survival of a perennial species such as Yadon's rein orchid.
Additional Surveys. Surveys should be conducted for new occurrences of Yadon's rein
orchid at the Bureau of Land Management's (BLM's) natural resource management area at old Fort
Ord. Large areas of the BLM land support Hooker's manzanita in maritime chaparral and could
support Yadon's rein orchid. Surveys of these areas by Jones & Stokes Associates in 1992 did not
identify Yadon's rein orchid, but Michael's rein orchid was recorded and could have been
misidentified because the surveys were conducted prior to flowering of either species (U.S. Army
Corps of Engineers 1992). If rein orchid populations occur at this site, management and enhancement
measures could be more easily applied than for occurrences on privately owned properties in
developed areas of the Monterey Peninsula.
Gowen Cypress
Description and Taxonomy
Gowen cypress is a small coniferous tree in the cypress family (Cupressaceae). This sparsely
branched tree grows 15-25 feet tall with a short, broad crown. The scale-like leaves are light green
to yellow-green and 1-2 mm long. Pollen-bearing cones are 3-4 mm long and 1.5-2 mm wide. The
globose seed-bearing cones are 12-25 mm in diameter and are tan, aging to gray. Seeds are dark
brown to black. (Hickman 1993; 60 FR 148:39326-39337, August 2, 1995; Sudworth 1967.)
Gowen cypress is distinguished from its Mendocino County conspecific pygmy cypress
(Cupressus goveniana ssp. pigmaea) by its lack of a long whip-like terminal shoot, lighter colored

leaves, and occurrence in Monterey County (Hickman 1993). The Gowen cypress is a smaller tree
than pygmy cypress when grown on fertile soils (Griffin and Critchfield 1972).
Listing Status
Gowen cypress was proposed for federal listing as threatened under the Endangered Species
Act in August 1995 (60 FR 148:39326-39337, August 2, 1995). It is not listed as threatened or
endangered under the California Endangered Species Act. CNPS considers this species to be rare and
endangered in California (List 1B) (Skinner and Pavlik 1994).
Distribution
Gowen cypress is known from only two occurrences, one occurrence on Huckleberry Hill on
the Monterey Peninsula and a second occurrence on the north side of Gibson Creek inland of the Point
Lobos Peninsula (Figure 16). Gowen cypress is sold horticulturally and is cultivated more widely than
it is naturally distributed.
Ecology and Habitat Requirements
Gowen cypress occurs in pygmy forest and maritime chaparral habitats. In pygmy forest,
Gowen cypress occurs as nearly pure stands, mixed stands with Bishop pine, and scattered individuals
within Bishop pine stands. These three general types of pygmy forest are referred to here as Gowen
cypress, mixed, and Bishop pine pygmy forest. Pygmy forest occurs only on the fifth marine terrace
(Jones & Stokes Associates 1994a). In addition to Gowen cypress and Bishop pine, pygmy forest
supports scattered, stunted Monterey pine and an understory dominated by chaparral shrubs such as
shaggy-barked manzanita (Arctostaphylos tomentosa), huckleberry (Vaccinium ovatum), and Hooker's
manzanita All three types of pygmy forest are found at Huckleberry Hill on the Monterey Peninsula.
The Gibson Creek site supports only Gowen cypress pygmy forest.
Pygmy forest occurs on Narlon, Huckleberry, and Sunridge soils (Jones & Stokes Associates
1994). Pygmy forest occurs where the soil is shallow, acid, strongly leached, and poorly drained and
has a claypan or hardpan. The three pygmy forest types may represent a sequence of soil development
with the Gowen cypress type occurring on the shallowest (4 inches) and most acidic (pH = 3.9) soils,
the mixed type on intermediate soils, and the Bishop pine type on the least extreme soils (20 inches
deep; pH = 5.7) (Jones & Stokes Associates 1994).
Gowen cypress occurs as scattered individuals in maritime chaparral at Gibson Creek, above
the site that supports Gowen cypress pygmy forest. The maritime chaparral is on Cienaba soils on
the inland granitic bedrock geologic formation. Dominant species in the maritime chaparral are
shaggy-barked manzanita, Hooker's manzanita, and chamise (Adenostoma fasciculatum).
Gowen cypress is fire adapted. The cones remain on the tree for many years and open in
response to the heat of a fire. Regeneration following fire is rapid and prolific. Gowen cypress

produces cones within the first few years of life, an adaptation typically associated with a frequent fire
regime. Sudworth (1967) reports that Gowen cypress bears abundant cones when only 2 to 3 feet tall.
In 1994, young trees were found with large numbers of mature seed cones at the site of the 1987
Huckleberry Hill fire. Suppression of fire in Gowen cypress stands could result in an increase in
diseases and pests in aging forests.
Gowen cypress is wind pollinated. Cones mature in the second season and may open without
fire, typically dispersing seeds in September or October (Sudworth 1967). Seeds are wind dispersed,
but are not light enough to be carried far from the parent plant (Sudworth 1967).
Reasons for Decline and Threats to Survival
Most of the historical occurrences of Gowen cypress are extant. There is some indication by
Coleman (1905) that Gowen cypress may have occupied a larger area on the Monterey peninsula. A
portion of the stand at Huckleberry Hill, including about 840 trees, was removed in the early 1980s
for the construction of Poppy Hills Golf Course (60 FR 148:39326-39337, August 2, 1995).
The stand of Gowen cypress at Huckleberry Hill is within the Huckleberry Hill Natural Area
and the S. F. B. Morse Botanical Reserve owned by Pebble Beach Company and Del Monte Forest
Foundation, respectively. The stand at Gibson Creek is on Point Lobos State Reserve and property
owned by the Big Sur Land Trust (Lobos Ranch) slated to be transferred to Point Lobos State Reserve.
Because Gowen cypress regenerates most prolifically following fire, fire suppression likely
poses a threat to the health of the species. Existing development surrounding the Hucklebeny Hill
cypress occurrence likely precludes the use of fire as a management tool. Future maintenance or
expansion of fire roads within the pygmy forest may also reduce the Gowen cypress population.
Invasion by aggressive non-native species such as pampas grass (Cortaderia selloana) and French
broom (Genista monspessulana) could threaten Gowen cypress regeneration (60 FR 148:3932639337, August 2, 1995).
Recommendations for Habitat and Population Recovery
Both occurrences of Gowen cypress are on protected sites. The Huckleberry Hill occurrence
is on privately owned land with an open space designation. The Pebble Beach Company has no
immediate plans for development on the portion of this site under its ownership.
The best management of Gowen cypress habitat would include fire as a management tool.
However, residential development surrounds the Huckleberry Hill occurrence and the use of fire as
a management tool would need to satisfactorily address the risks to life and property. The wildfire
at Huckleberry Hill in 1987 resulted in healthy stands of high-diversity, early-successional pygmy
forest, including many young Gowen cypress, but also caused the loss of homes. The tolerance of
Gowen cypress to extremely poor soil conditions probably keeps it from being overtaken by other trees
on sites of shallow, acidic soils even in the absence of fire. However, some form of vegetationCalifornia Department of Fish and Game
G:15079sten
29
Final Recovery Strategies for Six Coastal Plant Species
on the Monterey Peninsula
May 19%
clearing disturbance would likely benefit Gowen cypress. For example, pygmy forest trees and shrubs
could be cut and chipped and left to regenerate. This cutting and chipping method should be tested,
along with other vegetation clearing methods, and the best technique incorporated into management
measures. If permits and public acceptance can be obtained, the chipped material could be control
burned in blocks of habitat surrounded by fire roads. Management for Gowen cypress at Huckleberry
Hill should be integrated with management for Monterey clover and the pygmy forest community as
a whole.
1
The use of fire as a management tool is more viable at the Gibson Creek Gowen cypress
occurrence than at Huckleberry Hill because surrounding lands are sparsely developed. With the
appropriate fire roads and blacklines (preburned fuelbreaks) established, and under the proper weather
conditions, portions of the Gowen cypress forest could be control burned.
Experimental studies of the effects of various vegetation clearing techniques on Gowen
cypress regeneration are needed. Because the use of fire may be precluded, the use of other
management tools will be necessary to ensure the long-term health of pygmy forests supporting
Gowen cypress.
CONCLUDING REMARKS
Recommended recovery measures in this report include:
■ site-specific actions for the protection of existing populations,
■ species-specific vegetation management techniques to expand or enhance habitat, and
■ the identification of suitable unoccupied habitat on protected properties that could be used
for the establishment of new populations.
Coastal dunes milkvetch is known from only one occurrence of eleven fragmented patches on
private property subject to much recreational use. Improved protection of the existing population and
establishment of new populations on suitable habitat at Point Lobos State Reserve should be
conducted as soon as possible.
Pacific Grove clover was found at six new locations during the study, in addition to the five
from which it was previously known. This clover is not as severely threatened as it was thought to
be three years ago when only two occurrences were known, but the species is still in danger of
extinction. Most of the clover occurrences are on privately owned properties that receive various types
and levels of use. Pacific Grove clover is adapted to disturbance and does well under many of these
uses. Increased protection of existing populations and establishment of new populations in suitable
habitat at protected sites are recommended.

Occurrences of Monterey clover were recorded by the study for the first time since 10)89.
Although Monterey clover is a fire follower, the use of fire may not be feasible over most of the
suitable habitat of this species. Alternative forms of vegetation management are recommended to
create clover habitat, including the opportunistic use of a proposed fuelbreak in Monterey pine forest.
Establishment of a new population of Monterey clover on the fifth marine terrace near Gibson Creek
at Point Lobos State Reserve is recommended. Fire could be used as a management tool at this site.
Hickman's cinquefoil was thought to occur only at one small site on the Monterey Peninsula,
until a much larger population was found by Caltrans' botanists in San Mateo County. Species
recovery efforts should focus on protecting the San Mateo County occurrence, which is on private
property. Efforts should be made to locate additional potential populations along the central coast.
Improved protection of the existing Monterey Peninsula population and establishment of new
populations on suitable habitat at Lobos Ranch are recommended.
Yadon's rein orchid occurs in much greater numbers than was thought before 1995. All
occurrences of Yadon's rein orchid may not need to be preserved to ensure the long-term survival of
the species. Several large occurrences are on protected sites. It is recommended that the two largest
occurrences on private property planned for development be preserved and brought under protection.
Gowen cypress occurs at two locations on protected sites in pygmy forest and chaparral
habitats. Gowen cypress is a fire-adapted species, but the use of fire may not be feasible over all of
its habitat on the Monterey Peninsula. Alternative forms of vegetation management are recommended
to create habitat for Gowen cypress regeneration. The use of fire as a management tool at the Gowen
cypress pygmy forest near Gibson Creek at Point Lobos State Reserve is recommended.

Appendix A. Field Notes for Rare Plant Survey Sites
This appendix contains brief field notes taken by Jane Holte, consulting botatist under contract
to Jones & Stokes Associates, during spring 1995 surveys on the Monterey Peninsula, Point Lobos
State Reserve, Lobos Ranch and Monterra Ranch for Pacific Grove clover (Trifolium polydon), coastal
dunes milkvetch (Astragalus tener var. titi), Hickman's cinquefoil (Potentilla hickmanii), and
Monterey clover (Trifolium trichocalyx). Site numbers correspond to numbers shown in various
figures in the text of the report.
SURVEY NOTES
Site 1 - Area is dominated by African ice plant (Carpobrotus edule) or unvegetated. Area is dry,
rocky, and heavily trampled. No areas of suitable Pacific Grove clover or coastal dunes milkvetch
habitat were found.
Site 2 Area is dominated by African ice plant, kikuyu grass (Penniseturn clandestinum), or golfing
green. There is a marshy area, but golf green goes right to edge of marsh. No areas of suitable rare
plant habitat were found.
-
Site 3 - Dense pansa sedge (Carex pansa), coyote bush (Baccharis pilularis), and African ice plant
dominate the area. Much of this site is private land. Public land and roadsides were thoroughly
searched. Probably not suitable rare plant habitat.
Site 4 - Much of area was covered by dense pansa sedge or dune vegetation. Potential Pacific Grove
clover habitat was seen in wet swale areas found on the ocean side of the road but only cow clover
(Trifolium wormskioldii) was found.
Site 5 - A few Pacific Grove clover plants were found in old roadbed (located in sand dunes) and in
grassy area near flagpole. Other roadbed and wetland sites in dunes were thoroughly searched.
Grassy areas located in conference grounds immediately surrounding dunes were also searched. Many
of these grassy areas were dominated by tall, non-native grasses. Several other clover species were
found. Many of these clovers were going to seed and it is possible that additional Pacific Grove clover
occurs here but was not seen.
Site 6 - Marshy area dominated by willow and other wetland species. Area surrounded by dune. No
potential rare plant habitat seen.
Site 7 Pacific Grove clover found by D. Allen in an old roadbed in newly constructed dune habitat.
Surveyed and found population.

November 1995
Site 8 - Most of area is dominated by African ice plant and turf grasses. Cow clover was found, and
some areas of suitable Pacific Grove clover and coastal dunes milkvetch habitat were found along
road.
Site 9 - Areas dominated by pansa sedge and African ice plant. No potential Pacific Grove clover or
coastal dunes milkvetch habitat observed.
Site 10 - Most of the area on the ocean side of Seventeen Mile Drive has been disturbed and
revegetated in this location. Area inland of Seventeen Mile Drive is dominated by pansa sedge and
Afrcian ice plan.
Site 11 - Along ocean side of Seventeen Mile Drive, coastal dunes milkvetch found within fenced
"sensitive" plant area and in a few nearby patches to south of fenced area. Pacific Grove clover was
found only in fenced area where it was planted (Yadon pers. comm.). Area inland of 17 Mile Drive
along horse trail contained both coastal dunes milkvetch and Pacific Grove clover.
Site 12 - Pacific Grove clover and coastal dunes milkvetch were found in several patches along the
path and in the horse jumping area.•
Site 13 - Indian Village site. Known location of Pacific Grove clover and Hickman's cinquefoil.
While surveys were conducted, maintenance workers came and mowed and weed-whacked the site.
Weeds were cut right up to the fenced area, ensuring that no errant Hickman's cinquefoil would escape
the exclosure. Pacific Grove clover was mowed just as it was starting to set seed. The clover was
pointed out to the workers, who were unaware of it; however, they continued to mow it.
Site 14 - Little potential Pacific Grove clover habitat seen here. South end of location very wel and
dominated by reed grass (Calamagrostis sp.). Northern portion of location (near Stevenson School)
was much dryer and no clover was seen. No potentilla species were encountered. Fairway area is
solid golfing green and has no potential habitat for either Pacific Grove clover or Hickman's
cinquefoil.
Site 15 - Few clover encountered. Area either fairly dry woodland or very wet (several marshes
encountered). Pacific silverweed (Potentilla anserina ssp. pacifica) was found in several very wet
spots.
Site 16 - Pacific Grove clover discovered in mowed parking area. After later search, D. Allen reported
that Pacific Grove clover population extended into equestrian grandstand area as well.
Site 17 - Area dominated by tall grasses. This area is private land and was not thoroughly searched,
but no potential habitat for target rare plant species was seen.
Site 18 - This area is a private horse pasture and is heavily disturbed (mostly unvegetated). Little of
the area appears to be wet enough to support Pacific Grove clover or Hickman's cinquefoil. Area was
not thoroughly searched because it is private property.

November 1995
Site 19 - Most of greenbelt is dominated by African ice plant and annual grasses. No Pacfic Grove
clover and coastal dunes milkvetch were found, but several small wet areas of excellent habitat were
seen.
Site 20 Excellent potential habitat for Pacific Grove clover and coastal dunes milkvetch. Many
associates found, but no rare plants found.
-
Site 21 - Remnant dune habitat. Dominated by pansa sedge and European dune grass (Ammophilia
arenaria). Few marshes with cow clover.
Site 22 - Horse pasture on private land. Very disturbed, no wet areas with potential for Pacific Grove
clover or coastal dunes milkvetch habitat seen from street.
Site 23 - Coastal scrub with intermittent non-native grassland. Area dominated by ripgut brome
(Bromus diandrus) and wild oats (Avena sp.). No clover seen.
Site 24 - Area dominated by tall annual grasses, including big rattlesnake grass (Briza maxima) and
soft chess (Bromus hordaceus). Some wet drainage areas with California oatgrass (Danthonia
californica) and rushes (Juncus ssp.), but no clovers or milkvetch. Vegetation may be too tall for
these species.
Site 25 - Wet meadow with signs of previous disturbance. Pacific Grove clover found near trail.
Site 26 - Dramatic change in vegetation seen. Area seems to be dryer and dominated by tall annual
grasses (soft chess and wild oats), mustard (Brassica spp.), and other weedy species. Change in
vegetation seems to correspond to change in terrace shown on geology map.
Site 27 - Mostly tall grassy vegetation, including soft chess, big rattlesnake grass, and Italian ryegrass
(Lolium multillorum). A few wet areas with low vegetation, no clover or milkvetch seen.
Site 28 Area with pronounced mima relief. Many annual grasses, including big rattlesnake grass and
soft chess. Seems too dry for rare species. No clover seen.
-
Site 29 - West side of road is excellent potential habitat for Pacific Grove clover and coastal dunes
milkvetch. Mima relief with many clover and milkvetch associate species found in depressions,
including tufted hairgrass, coyote thistle (Eryngium sp.), meadow barley (Hordeum brachyantherum),
cut-leaf plantain (Plantago coronopis), and common toad rush (Juncus bufonius).
Site 30 Area on east side has less potential rare plant habitat. More annual grasses, especially big
rattlesnake grass. Tufted hairgrass gets very thick (almost 100% cover) in many spots. Some very
wet spots with reed grass. A few mima depressions with suitable habitat but the only clover found
was pin-point clover.
-
Site 31 - Many homes, appears to be private property. Area dominated by tall annual grasses.
California Department of Fish and Game A-3

Site 32 - Horse pasture with several large low areas with many clover, including Pacific Grove clover
and rushes.
Site 33 - Both sides of the road are private property. Unable to thoroughly search. East side of road
is sloped and probably drains too fast for good clover habitat. Many houses on the west side of the
road. Strip of land next to highway is excellent Pacific Grove clover and coastal dunes milkvetch
habitat. Very wet, many rushes and cow clover seen. It is actively grazed by cows.
Site 34 - Pacific Grove clover was seen in low, wet area at base of slope. Dryer areas and northern
section near San Jose creek dominated by annual grasses and mustard.
Site 35 Tall grasses. Not suitable habitat for Pacific Grove clover.
-
Site 36 - This area is a dryer slope, dominated by tall grasses and some shrubs. Not suitable habitat
for Pacific Grove clover.
Site 37 Level, grassy area at base of slope with Pacific Grove clover found in wet depression areas.
-
Site 38 - Area with the greatest relief, might be considered mima relief. Appears wetter than Site 37.
Vernal pools in depression areas. A few clovers found, but no Pacific Grove clover.
Site 39 - Many grassy areas would seem to be good clover habitat, but few found. Area seems very
dry now. Hop clover (Triplium campestre) and thimble clover (Trifalium (completely gone to seed)
were found.
Site 40 - Many houses now on this site. Area was not thoroughly searched. Some patches of hop
clover seen in open places.
Site 41 - Open areas and road in unburned Monterey pine (Pinus radiata) forest searched (south of
fire road). No clover seen.
Site 42 - Monterey clover and thimble clover found in open grassy area in chaparral understory in
previously burned Monterey pine forest.
Site 43 - Monterey pines very thick from top of the ridge west and north, down the slope. Trees about
a foot apart. Several forays made into the middle of this area, no clearings seen and little understory
vegetation. No apparent suitable habitat for Monterey clover.
Site 44 - Monterey clover and thimble clover found in disturbed open area long the road.
Site 45 No clover found. Area was covered with trees and very dry chaparral. Dead snags were
piled in many of the open areas. (There must have been some clearing done after the 1987 fire.)

Site 46 Many patches of clover, including thimble clover, whitetip clover (Trifolium variegatum),
bearded clover (Trifolium barbigerum), and rose clover (Trifolium hirtum) found. No Monterey
clover found. Many of the clovers were still blooming, so it is unlikely that Monterey clover was just
missed.
-
Site 47 - No clover found. Area is dry and open spaces were often dominated by annual grasses.
Site 48 - Area with very thick tree cover. Only edges surveyed. Few cleared areas, but they were
densely shaded.
Site 49 - There were many open grassy areas in chaparral understory that seem likely Monterey clover
habitat. Areas indicated by Vern Yadon as Monterey clover occurrences in 1988 were located and
surveyed (Yadon pers. comm.). Only one patch of dried tomcat clover (Trifolium willdenovii) was
found. It could be too late in season for Monterey clover.
Site 50 - Trees in pygmy forest get taller as you go toward the golf course. A dense (impenetrable)
understory of huckleberry (Vaccinium ovatum) and salal (Gaultheria shallon) forms. No clover
habitat seen except along roads. No clover seen in locations of Monterey clover identified by Vern
Yadon in 1988 (Yadon pers. comm.).
Site 51 Dense patches of rose clover seen along fire road near area indicated as a Monterey clover
occurrence by Vern Yadon in 1988. Little other clover habitat seen. It looks like the road has been
widened recently.
