NatureServe Status

Global Status: G3
Global Status Last Reviewed: 13Oct2000
Global Status Last Changed: 03Apr2001
Rounded Global Status: G3 - Vulnerable
Reasons: Currently known only from small populations in 3 counties in southwestern Idaho and 1 in northern Nevada. Recent findings indicate that this species may be somewhat more abundant than was originally thought, but it is restricted to thin volcanic substrates, and this habitat specificity limits the number of possible occurrences throughout its range.
Nation: United States
National Status: N3

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. Please refer to our Distribution Data Sources to find contact information for your jurisdiction.
