Identified threats were cattle grazing (trampling, herbivory), proposed development, water diversions, road maintenance, inadequate legal protection, stochastic events (in particular drought), and invasive (non-native) plants (USFWS 1994).
We considered reports of the USFWS and CDFW, data in the California Natural Diversity Database (CDFW 2016a), and personal communications from other biologists who also observed the species.
Although we conducted no soil tests, each of the 21 known occurrences is on or adjacent to a serpentine deposit according to geologic maps (Wiegers 2009, 2010) and/or geologist David Chipping (USFWS 2014).
This results in a substantial amount of seed germination within the circle of old leaves during the following year and with little seed germination beyond the circle (Chipping in USFWS 2014).

"Any one of them could head up a major criminal investigation for any police department in the U.S.," says Goddard, who was the chief criminalist of the Huntington Beach, California, police department when the USFW hired him to set up the forensics lab.
The lab suggests that you contact your state office of USFW, which conducts investigative and covert operations to follow up on leads.
The slice of the USFW budget that we get is only 2.8 percent - that's for all of law enforcement, not just the lab."
The contraband traffic in wild animals and wild animal parts is increasing rapidly, and the USFW lab is one of the few serious buffers helping to control it.
