Threat ImpactVery high - high

Range Extent250-1000 square km (about 100-400 square miles)

Number of Occurrences21 - 80

Rank Reasons

Currently known from about 30 occurrences, all within the San Bernardino Mountains of southern California. Mostly restricted to carbonate substrates. Such substrates are rare in this region and virtually all are currently under active, or maintained but currently inactive, mining claims. ORVs are another major threat in this area, which is a favorite for recreating southern Californians. It is not known if some of the many sites on federal (USFS) lands are protected.

Range Extent Comments

Range extent is about 155 sq mi in 2 main areas. The range is located in Riverside and San Bernardino counties, California, usually on carbonate soils.

Occurrences Comments

There are 32 known EO's and 2 are historic.

Threat Impact Comments

The main threat is from mining since the plant is endemic to carbonate soils. Other threats include ORV use.

Ecology & Habitat

Habitat

Usually on substrates derived from limestone or dolomite on dry rocky slopes and outwash plains. Sometimes found on sites underlain by granite, usually with an overlying wash of limestone materials. 2 populations are have been found on quartz substrates. 800-2000 m elevation, from blackbrush scrub to pinyon and pinyon-juniper woodland communities.
