<br />Annual sandwort Minuartia pusilla
<br />var. pusilla
<br />WS Annual sandwort is known from British
<br />Columbia, south to California, Nevada,
<br />and Arizona. In Washington it has been
<br />found in Grant, Chelan, Whitman,
<br />Spokane, Walla Walla, and Klickitat
<br />counties.
<br />G5T3T5 One population occupying
<br />approximately 23 acres is
<br />known to occur within the
<br />region.
<br />The primary threat to annual sandwort is
<br />damage from OHVs.
<br />Plains, open pine forest,
<br />chaparral slopes and dry
<br />rock cliffs. Elevations range
<br />from 25-7,900 feet; in
<br />Washington it is known to
<br />occur at 800 feet.
<br />April to June 3a, 3b, 3c, NNR-8 -
<br />Awned halfchaff
<br />sedge
<br />Lipocarpha
<br />aristulata
<br />BLM-S,WT This species is found from California north
<br />to Washington and west to Idaho,
<br />Wyoming, Utah, Arizona, Colorado, New
<br />Mexico, Kansas, Oklahoma, Texas,
<br />Minnesota, Iowa, Missouri, and Indiana. In
<br />Washington, awned halfchaff sedge is
<br />known from two recent occurrences along
<br />the Columbia River in Benton, Grant, and
<br />Franklin counties and five historical
<br />occurrences from Klickitat, Whitman,
<br />Benton, and Asotin counties.
<br />G5?/S1 Two populations
<br />occupying approximately
<br />2,718 acres are known to
<br />occur within the region.
<br />The current primary threat is hydrologic
<br />change.
<br />Wetlands along the
<br />Columbia River, wet soil
<br />and mud in bottomlands;
<br />sandbars and beaches;
<br />328-1,312 feet.

<br />Basalt daisy Erigeron basalticus SOC, BLM-
<br />S, WT
<br />Basalt daisy is endemic to a small area in
<br />Washington, approximately 11 by 3 miles.
<br />Exclusively along the Yakima River
<br />Canyon and Selah Creek.
<br />G2/S2 Five populations
<br />occupying approximately
<br />1,369 acres are known to
<br />occur within the region.
<br />Primary threats include basalt mining,
<br />railroad and highway maintenance and
<br />construction and potential spray drift from
<br />adjacent agricultural fields.
<br />Cliff crevices on basalt
<br />cliffs, in rocky canyons;
<br />Yakima River and Selah
<br />Creek. Associated with the
<br />Yakima Basalt Formation,
<br />which occurred during the
<br />late Miocene; 1,250-1,500
<br />feet.
<br />May to June NNR-2, NNR-3 -
<br />Beaked cryptantha Cryptantha
<br />rostellata
<br />Note: The name
<br />maintained on the
<br />December 2011 list
<br />was Cryptantha
<br />flaccida, but that was
<br />the incorrect name
<br />and C. rostellata is the
<br />correct name; C.
<br />flaccida is not on
<br />WNHP list and is
<br />common in WA
<br />(ISSSP 2015).
<br />BLM-S,
<br />WT
<br />Beaked cryptantha is known from Kittitas
<br />County, Washington south through
<br />Oregon to central California. In
<br />Washington, it is currently known in
<br />Kittitas, Grant, Klickitat, Garfield, and
<br />Asotin counties in the Columbia Basin
<br />physiographic province. Historically it was
<br />also known from Yakima and Walla Walla
<br />counties.
<br />G4/S2 Six populations occupying
<br />approximately 817 acres
<br />are known to occur within
<br />the region.
<br />Primary threats include grazing, erosion,
<br />and invasion of habitat by exotic species.
<br />Dry, open places; Most
<br />locations are within big
<br />sagebrush/bluebunch
<br />wheatgrass (Artemisia
<br />tridentata/Pseudoroegneria
<br />spicata) habitat types;
<br />however some occur within
<br />scabland
<br />sagebrush/Sandberg
<br />bluegrass (Artemisia
<br />rigida/Poa secunda)
<br />habitats; 600-2,900 feet.
<br />April to June 3b, NNR-6, NNR-7 -
<br />Beaked spike-rush Eleocharis
<br />rostellata
<br />BLM-STR,
<br />WS
<br />Beaked spike-rush is known from
<br />Vancouver Island to Nova Scotia, Canada
<br />south to northern Mexico and the Greater
<br />Antilles and in the South American Andes.
<br />In Washington, beaked spike-rush is
<br />currently known from Grant and Yakima
<br />counties.
<br />G5/S2 Six populations occupying
<br />approximately 563 acres
<br />are known to occur within
<br />the region.
<br />The primary threat is invasion of habitat by
<br />exotic species and increasing density of
<br />woody species.
<br />Marshes and boggy sites
<br />around lakes, in alkaline or
<br />highly calcareous areas,
<br />often around hot springs;
<br />also in coastal salt
<br />marshes; 500-1,850 feet.
