MCBCP Status<br />
The <strong>Base</strong> is in consultation with the USFWS regarding management of Upland habitats and<br />
species basewide, including the San Diego fairy shrimp and the pools it occupies. When<br />
this species was listed, the <strong>Base</strong> instituted measures to prevent and minimize impacts to the<br />
San Diego fairy shrimp and the vernal pools they inhabit. These measures are published as<br />
programmatic instructions for users and residents of the <strong>Base</strong> via <strong>Camp</strong> <strong>Pendleton</strong>’s <strong>Base</strong><br />
Order P3500.1M (Range and Training Regulations). Management details, survey<br />
information, etc., for the San Diego fairy shrimp are located in Appendix F, Section F.16.<br />
DISTRIBUTION<br />
Global<br />
The San Diego fairy shrimp is restricted to vernal pools in southwestern coastal California<br />
and extreme northwestern Baja California, Mexico. All known localities are below 700<br />
meters (2,300 feet) and within 65 kilometers (40 miles) of the Pacific Ocean, from Santa<br />
Barbara County south to northwestern Baja California (USFWS 1997c). They are also<br />
found in southern Orange County, California and in shallow pools on a mesa perched<br />
above the Santa Ana River (NatureServe 2005).<br />
Regional<br />
In 2003, approximately 22 ac of vernal pool habitat was mapped for the MHCP (AMEC et<br />
al., 2003). In 1998, approximately 78 ac of vernal pool habitat was mapped for the MSCP<br />
(City of San Diego 1998). During the 2002-2003 rainy season, a total of 2,516 vernal pool<br />
basins at 62 sites were mapped for the City of San Diego’s MSCP (City of San Diego<br />
2004b). As of 2006, the City reported that approximately 54 percent (1,369 pools) of all<br />
currently identified vernal pool habitat within the boundaries of the City subarea plan were<br />
conserved by covenant of easement, conservation easement, or dedication in fee title to the<br />
City (USFWS 2008i). According to USFWS files, about 7 occupied complexes are covered<br />
by the County of San Diego’s subarea plan; 2 have been conserved, and development has<br />
been proposed on at least 2 others. Management goals set forth in the Regional plan have<br />
not yet been realized on the conserved lands in the County subarea plan (USFWS 2008i).<br />
MCBCP<br />
San Diego fairy shrimp occur primarily in Victor, Oscar One, and Oscar Two training areas<br />
and in the Wire Mountain housing area (Figure 3-33). <strong>Base</strong>wide survey efforts conducted<br />
since 2005 indicated that 279 pools were occupied by San Diego fairy shrimp (USFWS<br />
