<br />Hoover's tauschia Tauschia hooveri SOC, BLM-
<br />S, WS
<br />Hoover’s tauschia is a regional endemic,
<br />extending from Toppenish Ridge in south
<br />central Yakima County, northward to the
<br />southeastern foothills of the Wenatchee
<br />Mountains in east-central Kittitas County.
<br />G2/S2 Twenty-eight populations
<br />occupying approximately
<br />13,911 acres are known to
<br />occur within the region.
<br />Orchard expansion and housing
<br />development may result in some
<br />degradation or loss of habitat. Herbicide
<br />spray drift may affect some populations.
<br />Grazing, OHV use, and road construction
<br />are also potential threats.
<br />The Hoover’s tauschia sites generally do
<br />not have enough vegetation present to
<br />carry a fire.
<br />Sagebrush scablands,
<br />often barren rocky clay.
<br />March to May 1b, 1c, NNR-3 -
<br />Kalm's lobelia Lobelia kalmii BLM-STR,
<br />WE
<br />Kalm’s lobelia occurs from Newfoundland
<br />to Pennsylvania, west to British Columbia,
<br />and Colorado to Hudson Bay and the
<br />southern Mackenzie District. In
<br />Washington, it occurs in Yakima County.
<br />G5/S1 One population occupying
<br />approximately 92 acres is
<br />known to occur within the
<br />region.
<br />Primary threats include habitat degradation
<br />from livestock, weedy species, and the
<br />sustainability of the habitat is dependent
<br />upon the steady flow of the natural spring.
<br />This species can apparently occur in a wide
<br />range of wetland types, including sphagnum
<br />bogs, stream and lake shores, wet
<br />meadows, and seeps and springs. The
<br />existing site in Yakima County has been
<br />degraded from past livestock use.
<br />Marl or peat bogs, along
<br />shores and in other wet
<br />places.
<br />Late July to
<br />August
<br />3b -
<br />Longsepal
<br />globemallow
<br />Iliamna longisepala BLM-S,
<br />WS
<br />Longsepal globemallow is a regional
<br />endemic of central Washington. It is
<br />known to occur only in Kittitas, Chelan,
<br />and Douglas counties.
<br />G3/S3 Forty-five populations
<br />occupying approximately
<br />15,482 acres are known to
<br />occur within the region.
<br />The primary threat is fire suppression.
<br />Additional threats include road construction
<br />and maintenance, logging, OHV use,
<br />recreation, grazing, and introduction of non-
<br />native species.
<br />Dry open hillsides and
<br />gravelly streamsides of
<br />sagebrush and open
<br />ponderosa pine forests;
<br />lower levels on the east
<br />side of the Cascade
<br />Mountains; 500-4,500 feet
<br />June to
<br />September
<br />NNR-6 -
<br />Miner’s candle Cryptantha scoparia BLM-STR,
<br />WS
<br />Miner’s candle is found in Washington,
<br />Oregon, California, Idaho, Nevada,
<br />Montana, Wyoming, Utah, and Colorado.
<br />In Washington, it is known to occur in
<br />Benton, Yakima, Grant, and Kittitas
<br />counties.
<br />G4?/S1 Four populations
<br />occupying approximately
<br />401 acres are known to
<br />occur within the region.
<br />Threats to this species include grazing,
<br />OHV use, development, and possible
<br />competition with exotic plants.
<br />Dry, open slopes and flats,
<br />commonly among
<br />sagebrush; gravel bars and
<br />alluvial slopes and thin
<br />gravelly soil over basalt;
<br />1,200-1,280 feet.
<br />May to June NNR-7 -
<br />Naked-stemmed
<br />evening-primrose
<br />Chylismia
<br />scapoidea ssp.
<br />scapoidea
<br />(synonym =
<br />Camissonia
<br />scapoidea ssp.
<br />scapoidea)
<br />BLM-S,
<br />WS
<br />Naked-stemmed evening-primrose occurs
<br />from eastern Oregon and Washington
<br />through southern Idaho to Wyoming,
<br />south to Colorado. In Washington, it is
<br />known only from Kittitas County.
<br />G5/S1 Two populations
<br />occupying approximately
<br />229 acres are known to
<br />occur within the region.
<br />Primary threats include gravel extraction,
<br />invasion by weedy species, and military
<br />training activities.
<br />Naked-stemmed evening-primrose is
<br />apparently adapted to some disturbance
<br />since it occurs on a sandy unstable
<br />substrate.
<br />Mostly in the sagebrush
<br />desert; especially on rocky
<br />or sandy soil; 600-900 feet.
<br />May to July 3b, NNR-7, NNR-8 -
<br />Nuttall's sandwort Minuartia nuttallii
<br />ssp. fragilis
<br />BLM-S,
<br />WT
<br />Nuttall’s sandwort is found in Washington,
<br />Oregon, California and Nevada. In
<br />Washington, it is known to occur in Grant
<br />County.
<br />G5/S1 Two populations
<br />occupying approximately
<br />884 acres are known to
<br />occur within the region.
<br />The primary threat is off-road vehicle use. Dry basalt scree slopes,
<br />open, gravelly benches, or
<br />limestone talus from open
<br />sagebrush hills to alpine
<br />slopes; 5,413-7,874 feet.
<br />April to May
<br />(August)
<br />1b, 1c, 2d, 3b, 3c 1b; also occurs in 3b

<br />Pauper milkvetch is endemic to eastern
<br />Washington. It is known to occur in
<br />Klickitat, Yakima, Kittitas, and Douglas
<br />counties, with historical records also from
<br />Benton and Franklin counties.
<br />G4T3/S3 Eleven populations
<br />occupying approximately
<br />11,491 acres are known to
<br />occur within the region.
<br />The primary threats to pauper milkvetch are
<br />from soil disturbing activities such as
