NatureServe Status

Global Status: G3
Global Status Last Reviewed: 02Jun2006
Global Status Last Changed: 02Jun2006
Rounded Global Status: G3 - Vulnerable
Reasons: Range is limited to central and southern California and western Nevada. However, it occurs in at least 7 counties in California with well over 20 occurrences. CNDDB suspects, but does not know if, there are more occurrences out there. The plant is small and probably easily overlooked. Although the Central Valley habitat for this plant may be largely gone, it's habitat in the Mojave may yet be vast and undersurveyed. Basic inventory work is needed.
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.

Other Statuses

NatureServe Global Conservation Status Factors

Range Extent Comments: Central and southern California (Fresno, Inyo, Kern, Los Angeles, Madera, Mono, and Tulare counties); Mineral county in western Nevada (Skinner and Pavlik 1994).

Area of Occupancy: Unknown 4-km2 grid cells
Area of Occupancy Comments: Area of occupancy is unknown since so few occurrences have been reported and/or have accurate sizes assigned to them.

Number of Occurrences: 21 - 80
Number of Occurrences Comments: One occurrence in Mineral County, Nevada (pers. comm. to M. Martinez from Jim Morefield, June 30, 1995); 14 sites noted for California (Reveal and Ertter 1976). As of April, 1996, over 20 occurrences are estimated to be distributed over at least 7 counties in California (Roxanne Bittman, personal communication). This plant is a California Native Plant Society List 4 suggesting there are many more populations in the field than the CNDDB currently knows of.

Population Size Comments: Few sites have population numbers in California. One site has 10,000 reported, one site states "thousands" were present, and one reported fewer than 50.

Number of Occurrences with Good Viability/Integrity: Very few to few (1-12)
Viability/Integrity Comments: The level of information is low for this taxon. At least 2 California populations are rated as good or better.

Overall Threat Impact: Unknown
Overall Threat Impact Comments: May be threatened by groundwater lowering and trampling by cattle (Skinner and Pavlik 1994).

Short-term Trend: Unknown

Long-term Trend: Decline of 30-70%
Long-term Trend Comments: Long term trend is estimated to be somewhat to substantial decline. This is based upon the knowledge that the lowland habitat this plant occurs in particularly in the Calif Central Valley area has been heavily modified to agriculture and urban uses.

Intrinsic Vulnerability Comments: So little is known about this species that "intrinsic vulnerability" is currently unknown.

Environmental Specificity: Very narrow. Specialist or community with key requirements scarce.
Environmental Specificity Comments: Alkaline places on dry lake beds, flats, sinks and meadows in the California Central Valley southward into the Mojave Desert and into Nevada.
