Rare Plant Monitoring
2009 Annual Report
Summary
Washington Rare Plant Care and Conservations Rare Plant Monitoring Project provides critically-
needed information on the status of Washington States rare plant species. Trained volunteers
monitor known occurrences of rare plants and report on their status and the habitat where theyoccur. Monitoring data collected under this project are provided to the Washington Natural
Heritage Program and to federal, state, and local land managers to inform short-term and long-
term conservation practices. In 2009, a total of 123 surveys of rare plant populations werecompleted throughout the state of Washington. Eighteen of these sites represented potentially new
occurrences for the Washington Natural Heritage Program. Volunteers successfully relocated the
rare plant species at 63% of the sites monitored. Reports were also provided on 3 additionalmonitoring attempts; however, the surveyors could not reach the sites due to access or time
constraints. A total of 85 volunteers participated in the project and 17 new volunteers were trainedin 2009.
Introduction
Washington Rare Plant Care and Conservation (Rare Care) initiated the Rare Plant MonitoringProject in 2009 to provide critically-needed information on rare plant populations in Washington
State. The project was developed in partnership with the Washington Natural Heritage Program
(WNHP), the agency responsible for tracking native biological diversity of the state. The focus ofthis project is the approximately 370 species of native plants considered to be endangered,
threatened or sensitive to decline or extirpation by WNHP. These plants face an ever-increasing
level of threat to extirpation due to ongoing loss or degradation of habitat and an ever expanding

occurrences specifically requested by land managers of public agencies where rare plant
populations occur and 2) Rare Cares focus species. Focus species were those that Rare Care
selected for comprehensive monitoring such that all of their occurrences on public lands weremonitored in a three to five year time frame.
High priority was also given to monitoring occurrences whose records in the WNHP database had
not been updated since 1990. Within this group, higher emphasis was placed on species
considered to be threatened or endangered under the WNHP ranking system. Finally, priority wasplaced on occurrences that were not located by Rare Care volunteers in previous years. After three
attempts on an occurrence by at least two different surveyors, Rare Care considers the occurrence
to be extirpated and will no longer include it on the list of monitoring priorities in future years.
2009 Monitoring Results
During the 2009 field season, Rare Care volunteers completed 123 surveys of rare plantoccurrences throughout Washington State representing 78 species (Table 1). Attempts were made
to monitor an additional three occurrences; however, they could not be reached due to access or
time constraints. For these three sites, volunteers provided reports that include valuable accessinformation for future surveyors. At 63% of the monitored sites, volunteers found and documented
the rare plant occurrence. Twenty-one of the 77 rare plant populations found consisted of fewer
than 50 individuals. It is unknown whether these populations are stable or in decline. Surveyorsreported invasive species at 48% of the sites (Table 2) and reported potential land use and
management concerns at 43% of the sites (Table 3). Original data sheets were provided to WNHP
and copies were provided to land managers for occurrences monitored under their jurisdiction.
For the third consecutive year, Rare Care organized a rare plant monitoring weekend. Volunteersand staff gathered for two days to assist WNHP with their three-year review of Wenatchee
Mountain endemic and rare plant species. In 2009, the monitoring weekend focused on areas inand around Upper Naneum basin in Kittitas County. In addition to compiling plant lists and

In addition to these five new populations, Rare Care volunteers documented an additional 13
potentially new locations in 2009 for rare plants in other parts of the state. These populationsoccurred outside the recorded extent of existing element occurrences in the Washington Natural
Heritage Program database. They should be reviewed by WNHP to determine if in fact theyrepresent new occurrences. Five of the sites were documented at the Klickitat Wildlife Area and
included thousands of individuals each ofCalochortus longebarbatus var. longebarbatus,
Lomatium suksdorfii, and Trichostema oblongum; a population of over 500 individuals of
Penstemon barrettiae; and a population of over 200 individuals of what appears to be a hybrid of
Ranunculus triternatus andR. glaberrimus. A specimen from this last population will be collected
in 2010 and sent to an expert for identification. Another population ofTrichostema oblongum wasalso found in Klickitat County, at Conboy National Wildlife Refuge (NWR). This second
population contained approximately 200 to 500 individuals. A small populationEryngiumpetiolatum with less than 200 individuals was also discovered at Conboy NWR. Finally, one other
potentially new population of a rare plant species was reported from Klickitat County: a singleplant ofSpiranthes porrifolia on private land.
Elsewhere in the state, volunteers documented five potentially new populations of sensitive plantspecies. New populations ofErigeron howellii and Sullivantia oregana were found on bluffs and
steep slopes near Skamania, Washington in the Columbia River Gorge National Scenic Area.
Population sizes estimated for these two new occurrences were 313 and 140, respectively. A largepopulation of over 600 Carex comosa individuals was reported from a state park in King County.
Also in King County, three groups ofLycopodium dendroideum, containing a total of 30 stems,
were documented in the Mt. Baker-Snoqualmie National Forest. Finally, a population of
Penstemon eriantherus var. whitedii containing 150 individuals was reported from a site near
Wenatchee, Washington.
Of the 127 populations assigned to volunteers for monitoring, 25 were not attempted this seasondue to a variety of reasons. In most cases, the volunteer simply did not have time to complete the

New4 Y The area is not currently grazed, but would suffer if this occurred. ATVs
and trail bikes could potentially damage the area, although the area is
signed to prevent such action. Any acitivities that deepen the stream
channel would prevent flooding of the surrounding flood plain, leaving
these species high and dry. In addition, local folks camp at the Canyon
Creek trailhead at a time when TROB and CALOL are both in flower.

11 Y Very little evidence of human use, some beverage containers on shore,
but old and very few. Adjacent land use will impact the quality of these
bogs. It is fortunate that the bogs are separated from the road system by
topographic ridges. ORV trail to the south appears to get used, but not a
lot of use of the bogs.
Carex praeceptorum 1 N Yes, There is some trampling in the bog area at the north end of the lake,
but it is limited to the lakeshore areas of the bog, probably from fisherman.
We searched less trammeled areas as well and did not find the plant.
Carex saxatilis var. major 11 Y I only found a few CASA, but they are at a seldom-visited part of this
heavily used lake Trampling from the occasional fisherman may impact

(Y/N) Adjacent Land Use and Management Comments
Cryptantha leucophaea 22 N Area is seriously degraded due to heavy ATV use and extensive increase
of alien species.
Cypripedium fasciculatum 6 Y This area is bordered on two sides by a subdivision of vacation homes
with an abundance of small vehicles. A number of old roads run through
the area and garbage has been dumped in piles, then partially buried, in
the past. Neither activity seems to be current. Also, young Douglas firs are
growing among the Ponderosa which will eventually alter habitat for
CYFA. Marked herbivory of Cypripedium montanum was noted in the
area. Most flowering heads had been bitten off (see photos). A fewscattered flowering plants remained, and one clump preotected by a rose
shrub had several flowers. It seems plausible that the decline in shape IDs
of C. fasciculatum found (50% only) and the reduction in stem number of
those located may be due to herbivory.
Cypripedium fasciculatum 11 Y Dead fir trees throughout the area up to the old location, Pine beetles?
Spruce bud worms? Fir tree management needed for diseased trees. The
old population may be lost due to mycorrhizal disruption. The new
population has two plants right on the edge of trail. Maybe advise no trailwidening in that area.
Damasonium californicum 3 Y Fence is down on the west side so cattle and horses have access to this
pond, where the horses have been observed in the pond, and where much
fecal material accumulates. Cows graze the perimeter where yound
DACA12 grow. No direct evidence of herbivory of the older plants. Fences
need to be fixed and checked on a regular basis to prevent infiltration by
neighboring cattle and horses. A bigger concern is controlling the
proliferation of reed canary grass which is over running the majority of the
pond (very little DACA12 observed amongth the canary grass).
Erigeron howellii New4 Y This area is increasingly being explored and hiked by local people.
Erigeron piperianus 51 Y Cow pies were everywhere - very heavily grazed but no damage to ERPI3

Lomatium suksdorfii New4 Y Some of the population is on a private parcel showing minor evidence of
grazing and perhaps prior agricultural practices. As mentioned above,
there may be a threat due to grazing. This is a fairly high quality grassland
and oak forest with several other rare plants present.
Lycopodium dendroideum 10 N Survey area was a working quarry which may have expanded or changed
since previous survey in 1992.
Lycopodium dendroideum New4 Y Site 1 is vulnerable to foot traffic, be it human or otherwise.
Orobanche californicassp. grayana
None6 N Yes. The area has been drained & grazed but most species persist insuitable habitat.
Pedicularis rainierensis 49 Y Disturbance: possible disturbance from ridge-top road erosion of
talus/scree and sand. Also, some recreation-related items were found
scattered (cans, ski pole, scarf, etc). Expansion of resort could threaten
population, especially any new disturbance along ridges.
Pedicularis rainierensis 49 Y Disturbance from removal of ridgetop to construct new lift landing. Ridge
was cut vertical on southern side and is likely unstable. Also, some
construction debris remains as well as installation of plastic poles to mark
ski hazards or ski boundaries. Impacts to population are unknown.
Penstemon eriantherus
var. whitedii
5 N Logging is occurring in the araea and prescribed burns are planned.

4 Y The northern sites are right along the road; the disturbed soil is likely from
road grading.
Phacelia minutissima 1 N Elk grazing in the vicinity.

Sullivantia oregana New4 Y This area is increasingly being explored and hiked by local people.
Trichostema oblongum New4 Y The road gets light use each day. The plant is on the edge of the road so
probably is affected by grading of the road in spring. There may be some
cattle drives along the road, but these don't look like they affect this small
annual. Tracks off to the side of the road indicated that someone had
driven off the road along the private fence, probably to fix the fence. This
is a site where there are numberous CALOL, ERPE7 and ORBR within
feet of road.
Trichostema oblongum New4 Y The area is not currently grazed, but would suffer if this occurred. ATVsand trail bikes could potentially damage the area, although the area is
signed to prevent such action. Any acitivities that deepen the stream
channel would prevent flooding of the surrounding flood plain, leaving
these species high and dry. In addition, local folks camp at the Canyon
Creek trailhead at a time when TROB and CALOL are both in flower.
Trillium parviflorum 1 Y Surrounded by privately-owned forest land that motorized vehicles/bikes
use. Climbers too.
