Rank Reasons

Hecastocleis shockleyi is a regional endemic and known from Nevada and California. While it is restricted in its range it does appear to be relatively common. Some 20-25 occurrences are documented in California, but is expected that this species is under observed. Further, the habitat is generally inaccessible. It is believed that even older reports of this species in the Inyo and Mono Counties and western Nevada are probably still extant. The habitat this species occupies is also common so this supports the idea that it is under observed. This species tends to occur scattered where it is found and is not usually a dominant component of the vegetation (CNPS, CNDDB).

Range Extent Comments

This plant occurs in western Nevada and into the deserts of California in Inyo, Mono, San Bernardino and Riverside counties.

Occurrences Comments

There are approx. 20-25 occurrences in California and more in Nevada. It is not actively tracked in either state. There is quite a bit of speculation that there are many more occurrences in the desert currently undocumented.

Threat Impact Comments

There may be some threat of mining at some sites since this plant can occur on calcareous substrate.
