Range Extent20,000-2,500,000 square km (about 8000-1,000,000 square miles)
Number of Occurrences21 - 300
Rank Reasons
The species' range is limited to two counties in Oregon and seven in California. Plant appears to tolerate moderate disturbance and total numbers are not extraordinarily high (<10,000), though details on pop numbers is not known. The plant is found on serpentine or alkaline soils. It may be subject to overgrazing, mining and OHV use.
Range Extent Comments
Collections have been made from Lake and Klamath Counties in Oregon and Colusa, Lake, Lassen, Napa, Siskiyou, Trinity and Shasta Counties in California. Most of the population is centered in southern Klamath County and Siskiyou County.
Occurrences Comments
About 12 occurrences currently noted in the Oregon Natural Heritage Program. Considering that California does not computer-track the species, the total number is certainly higher. In CA, the plant occurs in seven counties including Colusa, Lake, Lassen, Napa, Shasta, Siskiyou and Trinity. The file is very thick (3") and there must be many sites in it. There could be anywhere from 35-100+ occurrences in total.
Threat Impact Comments
Populations occur in mining areas, along roads, and within grazed pastures. Plants appear to tolerate moderate disturbances. Due to its occurrences in open meadow and flat areas, this plant is probably subject to OHV use and grazing, which could be heavy in some places.
Ecology & Habitat

Habitat

This species grows in damp meadows and open flats, usually alkaline in nature, although found on serpentine soils in California. In Oregon, plants were found growing under and within Sarcobatus vermiculatus, which was probably providing shelter from the grazing cows.
