Threat ImpactHigh
Range Extent250-1000 square km (about 100-400 square miles)
Number of Occurrences6 - 80
Rank Reasons
Only known from riparian habitats in Madera and Mariposa counties, California. Potentially threatened by logging, and, erosion, hydro projects, grazing and recreational development. Most known sites are on the Sierra NF where they probably receive at least partial protection. Historically, there were over 40,000 plants known at all sites but these counts are old. Higher levels of protection are needed. Updated site visits are also needed.
Range Extent Comments
Occurs in 2 counties in the California Sierra Nevada Mountains.
Occurrences Comments
24 known occurrences but only 3 seen recently (after 2002).
Threat Impact Comments
Threats listed include logging, erosion, recreation, development, road maintenance, small hydro projects and grazing.
