2008i & Mabb pers. comm. 2009). For detailed information on the San Diego fairy shrimp,
survey information and its management on Base see Appendix F, Section F-16.
Additionally, the USGS has developed a genetic test for fairy shrimp cysts to distinguish
between the species that can be utilized in wet or dry conditions, which should significantly
aide future surveys and reduce impacts to vernal pools (USGS 2008g).

(PHOTO SOURCE: GARY A. MONROE @ USDA-NRCS PLANTS DATABASE)
San Diego button-celery is a
perennial or biennial herb arising
from a taproot, which occurs in
vernal pools/IEWs. It has a
spreading to erect habit and can
grow to a height of 16 inches or
more (USFWS 1998b). The
flowers occur on short stalks with
rigid spiny bracts, and the greygreen
stems and leaves are
toothed, which give it a prickly
appearance (USFWS 1998b). The
species is threatened region-wide
by urbanization, foot traffic, offroad
vehicles, grazing agriculture
and watershed alteration
(drainage).
Federal Status
San Diego button-celery was listed as endangered on 3 August 1993 (USFWS 1993c).
Critical habitat has not been proposed for this species. San Diego button-celery is included
in the recovery plan for the listed species of southern California vernal pools (USFWS
1998b).
California Status
The CDFG listed San Diego button-celery as an endangered plant in California in July
1979 (CDFG 2005).
