Rank Reasons
Astragalus bicristatus is endemic to California and is known from Los Angeles, Riverside, and San Bernardino counties. The California Native Plant Society considers this species rare, but occurring in sufficient numbers and distributed widely enough that currently the threat of extinction is low (2001). The CNPS does not consider it very endangered either (2001). A. bicristatus is found in lower montane coniferous forest and upper montane coniferous forest between 1700 and 7245 meters in elevation (CNPS 2001). Hickman (1993) indicates that it occurs in open rocky areas.
Threat Impact Comments
Astragalus bicristatus is possibly threatened by mining and vehicles (CNPS 2001).
