<br />Coyote tobacco Nicotiana attenuata BLM-S,
<br />WS
<br />Southern B.C. and northern Idaho and
<br />Montana to Baja CA, New Mexico and
<br />northwest Mexico, east of the Cascades.
<br />In Washington, it is known to occur in
<br />Douglas, Grant, Kittitas, Klickitat, and
<br />Yakima counties. Historic sites are known
<br />from Chelan and Franklin counties.
<br />G4/S2 Thirteen populations
<br />occupying approximately
<br />1,794 acres are known to
<br />occur within the region.
<br />Threats to coyote tobacco include invasive
<br />plants and activities leading to increased
<br />erosion, including livestock grazing,
<br />agriculture, military training activities, OHV
<br />use, herbicides and road maintenance.
<br />Dry, sandy bottom lands,
<br />dry rocky washes and in
<br />other dry open places; 400-
<br />10,000 feet.
<br />June to August NNR-6 -
<br />Dwarf evening-
<br />primrose
<br />Eremothera
<br />pygmaea (synonym
<br />= Camissonia
<br />pygmaea)
<br />BLM-S,
<br />WS
<br />Regional endemic known from eastern
<br />Washington (Benton, Douglas, Franklin,
<br />Grant, and Kittitas counties), eastern
<br />Oregon (Gilliam, Grant, Harney, and
<br />Wheeler counties), and Idaho (Jerome
<br />County).
<br />G3/S3 Nineteen populations
<br />occupying approximately
<br />6,564 acres are known to
<br />occur within the region.
<br />Primary threats to dwarf evening-primrose
<br />include resource extraction (gravel pits),
<br />road construction and herbicide drift.
<br />Invasion by non-native weedy species will
<br />likely pose a threat in the future. Illegal OHV
<br />use and off-site irrigation.
<br />Dwarf evening-primrose occurs in habitats
<br />that are maintained in an open condition by
<br />erosion and the generally harsh
<br />environment. Due to the unstable nature of
<br />the habitat and the annual life cycle, it is
<br />likely that the number, size and location of
<br />the populations vary from year to year.
<br />Sagebrush and lower
<br />foothills; unstable soil or
<br />gravel in steep talus slopes,
<br />dry washes, banks and
<br />roadcuts; growing with big
<br />sagebrush and wild
<br />buckwheat.
<br />May to July 3b, NNR-7, NNR-8 -
<br />Fuzzytongue
<br />penstemon
<br />Penstemon
<br />eriantherus var.
<br />whitedii
<br />BLM-S,
<br />WS
<br />Fuzzytongue penstemon is endemic to
<br />Washington and is found in Franklin,
<br />Chelan, Kittitas, Douglas, Klickitat and
<br />Lincoln counties, Washington.
<br />G4/S2 Eight populations
<br />occupying approximately
<br />3,335 acres are known to
<br />occur within the region.
<br />Primary threats include grazing and off-road
<br />vehicle use. Some existing populations
<br />occur on private land, and in one instance,
<br />are in an area heavily used for agriculture.
<br />Dry, open places in
<br />between shrubs; in the
<br />plains, valleys, and
<br />foothills, sometimes
<br />ascending to moderate
<br />elevations in the
<br />mountains; associated with
<br />big sagebrush (Artemisia
<br />tridentata), antelope
<br />bitterbrush (Purshia
<br />tridentata), purple sage
<br />(Salvia dorrii), buckwheat
<br />(Eriogonum sp.), and
<br />rabbitbrush
<br />(Chrysothamnus
<br />nauseosus); 525-3,835
<br />feet.
<br />May to June 3c -
<br />Geyer's milkvetch Astragalus geyeri BLM-S,
<br />WT
<br />Geyer’s milkvetch is known from
<br />southeast Oregon to California and
<br />Nevada and eastward through southern
<br />Idaho to Wyoming and Utah and Grant
<br />County, Washington.
<br />G4/S1 Eight populations
<br />occupying approximately
<br />1,689 acres are known to
<br />occur within the region.
<br />Primary threats include agricultural
<br />conversion, OHVs, and grazing.
<br />Arid sandy soils, flat to
<br />dunes; sandy desert,
<br />especially on dunes; 630-
<br />670 feet.
