<br />Piper's daisy Erigeron piperianus BLM-S,
<br />WS
<br />Piper’s daisy is a regional endemic,
<br />occurring only in the Columbia Basin of
<br />Washington. It has been found recently in
<br />Adams, Benton, Douglas, Franklin, Grant,
<br />Klickitat, and Yakima counties and
<br />historically in Kittitas County.
<br />G3/S3 Forty-two populations
<br />occupying approximately
<br />23,158 acres are known to
<br />occur within the region.
<br />The primary threats to Piper’s daisy include
<br />habitat loss due to agricultural
<br />development, overgrazing and weedy
<br />annual plants.
<br />Piper’s daisy is most common in
<br />undisturbed areas of the sagebrush steppe;
<br />however, it has also been reported growing
<br />in grazed and burned sites, so can
<br />withstand some disturbance.
<br />Dry, open places, often
<br />among sagebrush; 400-
<br />2,250 feet.

<br />Snake River
<br />cryptantha
<br />Cryptantha
<br />spiculifera
<br />BLM-S,
<br />WS
<br />Snake River cryptantha is a regional
<br />endemic, known from central Washington
<br />and eastern Oregon to northeastern
<br />California and northern Nevada, east
<br />through the Snake River Plains of Idaho,
<br />and western Montana. In Washington, it
<br />has been in the Okanogan Highlands,
<br />Eastern Cascades and Columbia Basin
<br />physiographic provinces.
<br />G4?/S2? Nine populations
<br />occupying approximately
<br />7,193 acres are known to
<br />occur within the region.
<br />Primary threats include agricultural
<br />conversion, grazing, off-road vehicle use,
<br />and irrigation related groundwater changes.
<br />Sandy knolls and badlands
<br />and talus at low elevations;
<br />dry, open, flat or sloping
<br />areas in stable or stony
<br />soils.

<br />Snowball cactus Pediocactus
<br />nigrispinus
<br />(synonym =
<br />Pediocactus
<br />simpsonii var.
<br />robustior)
<br />BLM-S,
<br />WS
<br />Snowball cactus ranges from eastern
<br />Washington to Nevada. In Washington, it
<br />has been found in Yakima, Kittitas,
<br />Chelan, Douglas, and Grant counties.
<br />G4/S2 Fourteen populations
<br />occupying approximately
<br />11,895 acres are known to
<br />occur within the region.
<br />The primary threat to snowball cactus is
<br />collecting by cactus collectors.
<br />Thin, rocky soil on ridge
<br />tops, desert valleys and low
<br />mountains; found at
<br />elevations from 1,000 to
<br />4,000 feet in Washington;
<br />associated with scabland
<br />sagebrush (Artemisia
<br />rigida).

<br />Erythranthe
<br />suksdorfii (synonym
<br />= Mimulus
<br />suksdorfii)
<br />
<br />BLM-S,
<br />WS
<br />Suksdorf’s monkeyflower ranges from
<br />California to Washington, Montana,
<br />Wyoming, Colorado, and Arizona. In
<br />Washington, it occurs in Benton, Chelan,
<br />Grant, Kittitas, Klickitat, and Yakima
<br />counties.
<br />G4/S2 Twenty-five populations
<br />occupying approximately
<br />8,776 acres are known to
<br />occur within the region.
<br />Degradation of habitat by livestock,
<br />agriculture, and military training activities.
<br />Open, moist, or rather dry
<br />places, from the valleys
<br />and foothills to rather high
<br />elevations in the
<br />mountains; associated with
<br />sagebrush steppe.
<br />May to August NNR-6, NNR-7 -
<br />Wanapum
<br />crazyweed
<br />Oxytropis
<br />campestris var.
<br />wanapum
<br />SOC, BLM-
<br />S, WE
<br />Wanapum crazyweed is known only from
<br />Saddle Mountain, Grant County,
<br />Washington in the Columbia Basin
<br />physiographic province.
<br />G5/S1 One population occupying
<br />approximately 1,919 acres
<br />is known to occur within
<br />the region.
<br />Primary threats include past and potential
<br />future land uses include grazing, off-road
<br />vehicle use, mineral and gas exploration,
<br />and rock hounding. Very little is known
<br />about the ecology of Wanapum crazyweed.
<br />It occurs in a harsh environment where
<br />mature individuals probably face little
<br />competition from other vegetation.
<br />Gravelly floodplains of the
<br />Columbia River; big
<br />sagebrush/bluebunch
<br />wheatgrass.
<br />May to June 3c -
<br />White eatonella Eatonella nivea BLM-STR,
<br />WT
<br />White eatonella is known from the Great
<br />Basin, southeast Oregon, western
<br />Nevada, and Washington. In Washington,
<br />it occurs in Grant and Kittitas counties.
<br />G4G5/S1 Seven populations
<br />occupying approximately
<br />853 acres are known to
<br />occur within the region.
<br />Primary threats include trampling and
<br />disturbance to the substrate by domestic
<br />livestock, gravel extraction, disturbance
<br />from recreationalists (rock climbers,
<br />bicyclers, and OHV uses), disturbance from
<br />activities associated with military training,
<br />and invasion by exotic species. Its habitat
<br />appears to suggest that it is a poor
<br />competitor with other vegetation.
<br />Dry, sandy desert or
<br />volcanic areas; populations
<br />are on bare soil in sparsely
<br />vegetated sagebrush
<br />steppe, associated with
<br />other annuals.
