NatureServe Status

Global Status: G2
Global Status Last Reviewed: 15Apr1997
Global Status Last Changed: 30Jul1997
Rounded Global Status: G2 - Imperiled
Reasons: A Washington State endemic with a total range of about about 1010 ha. Although the total number of surviving occurrences is greater than 20, these are effectively small, isolated sub-populations, rather than true populations. While some populations have been lost due to conversion to agriculture and due to grazing practices, there appear to be significant amounts of suitable habitat which are not currently occupied. The taxon appears to have disappeared from portions of its historic range in the Palouse grasslands of Spokane and Whitman counties.
Nation: United States
National Status: N2

U.S. & Canada State/Province Status
Due to latency between updates made in state, provincial or other NatureServe Network databases and when they appear on NatureServe Explorer, for state or provincial information you may wish to contact the data steward in your jurisdiction to obtain the most current data.

Comments on USESA: Was previously a candidate, but was removed from candidacy on February 28, 1996 in a notice of review.
U.S. Fish & Wildlife Service Lead Region: R1 - Pacific

NatureServe Global Conservation Status Factors

Range Extent Comments: The range includes portions of Lincoln, Adams, Whitman and historically Spokane counties. The range is encompassed within the Columbia Basin and adjacent channelled scablands and Palouse.

Number of Occurrences: 6 - 20
Number of Occurrences Comments: There are currently 26 occurrences in the WNHP data base. However, the 26 can (and perhaps should) be grouped into 6 or 7 populations.

Population Size Comments: A reliable estimate of the total number of individuals is not available, although it is probably at least 5,000 to 10,000. Population size ranges from 1 to greater than 500. The total area occupied by the taxon probably is less than 2,500 acres.

Overall Threat Impact Comments: Potential threats include conversion of land, overgrazing, application of herbicides, competition with non-native species, and altered hydrologic conditions.

Short-term Trend: Decline of 10-30%
Short-term Trend Comments: Although new occurrences have been found in recent years, several historically known sites (primarily those in the Palouse) have apparently been lost. Other occurrences have apparently been reduced by livestock grazing.

Intrinsic Vulnerability Comments: The taxon is apparently tolerant of at least moderate levels of livestock grazing. It also appears to respond favorably in a limited number of sites to disturbance.
