Rank ReasonsEndemic to California, Lupinus padre-crowleyi is known from about 8 extant occurrences in Inyo, Mono, and Tulare Counties. Many have not been visited in the past 20 years and should be resurveyed. These new surveys should provide data on population sizes, occurrence ranks and updated threats and disturbances. Known threats include overgrazing, OHV use, other recreational uses, camping, road maintenance and more. The threats seem to be pervasive and ongoing. All occurrences on Forest Service Land.
Range Extent CommentsCalifornia endemic found in Inyo, Mono, and Tulare counties.
Occurrences CommentsThere are 12 known occurrences; 4 of these are historical. The historical ones may still be extant, but need rechecking.
Threat Impact CommentsSeveral occurrences list heavy cattle grazing as a threat to this plant. The next most frequently listed threat is a combination of recreational activities including the development of cabins and lodges, road building and maintenance, trail use and camping. Off-highway vehicle use is also listed on some occurrences. The threats seem to be wide in scope and fairly severe and immediate. All recently visited occurrences have threats.
