Rank Reasons

There are twenty-nine occurrences in California and possibly eight or more from Baja California, Mexico. Threats include trampling by trail hikers, grazing and timber harvest. Many occurrences are historic and should be surveyed to determine if plants are extant, to estimate population size, and to document threats.

Range Extent Comments

In the United States, it occurs in San Diego and Riverside Counties of California. In Mexico, it is found in Baja California (Hickman, 1993).

Occurrences Comments

In California, there are 29 occurrences presumed extant. Seven are based on references from between 1920 to 1980, and the rest are from 1980-1996 (California Department of Fish and Game, 1997). There are eight occurrences in Baja Mexico, based on GBIF occurrence records. However, none of these records are recent.

Threat Impact Comments

There are multiple threats in California including logging, grazing, recreation, and foot traffic near recreational trails. One occurrence is found within a timber stand and others are nearby timber harvest sites (CNDDB 2017). Threats in Baja Mexico are not known.
