Threat ImpactVery high - high
Range Extent250-1000 square km (about 100-400 square miles)
Number of Occurrences21 - 80
Rank ReasonsNarrowly endemic to the eastern end of the San Bernardino Mountains in southern California. There are about 48 occurrences but a number of sites are in poor condition. Heavy recreational use, including off-road vehicle use, and ski area and campground development, is adversely affecting the species' habitat. Trampling and grazing by livestock is also a threat.
Range Extent CommentsEndemic to California and found only in the San Bernardino Mountains (Sclafani 2006).
Occurrences CommentsForty-nine known occurrences but one of those is extirpated.
Threat Impact CommentsThis species faces many threats, which remove available habitat. The following are threats to this species: off-road vehicle use, dumping, exotic species, development for campgrounds and ski areas, burro grazing, trampling, fuelwood harvesting, mining and timber harvesting (CNDDB 2003, CNPS 2001, USFWS 1995).
Ecology & Habitat
Habitat
Primarily on pebble plains (dense clay soils, usually covered with a cobble pavement of quartzite). Also known from pine forests, dry sagebrush scrublands, and other habitats. 1800-2800 m elevation.
Ecology
Sprouts from the root crown after a fire or other top-killing disturbance (Sclafani 2006). However, Eriogonum kennedyi, a host plant for the species is not tolerant of fire.
