lands (USFWS 1998e); however, on 8 December 2004 critical habitat for this species was
proposed (USFWS 2004c). On Camp Pendleton, 917 ac of ‘‘mission-essential’’ training
lands were proposed to be excluded from designation of critical habitat under Section
4(b)(2) of the ESA. On 13 December 2005, the USFWS issued its final critical habitat for
thread-leaved brodiaea. A total of 597 ac in Los Angles and San Diego Counties was listed.
All locations on Camp Pendleton were excluded under Sections 4(a)(3) and 4(b)(2) of the
ESA (USFWS 2005d). On 11 February 2011, a final revised critical habitat designation
was reissued by the USFWS, and all known locations considered on Camp Pendleton for
critical habitat designation were excluded under Sections 4(a)(3) of the ESA (USFWS
2011a). No recovery plan has been developed by the USFWS to date.
California Status
The CDFG listed thread-leaved brodiaea as an endangered plant species in January 1982
(CDFG 2005).
Regional Status
Thread-leaved brodiaea is a covered species in the following southern California NCCP
documents:
• Fieldstone/La Costa & City of Carlsbad.
• MHCP, City of Carlsbad Habitat Management Plan.
• MSCP, City of Chula Vista Subarea Plan.
• MSCP, City of La Mesa Subarea Plan.
• MSCP, City of Poway Subarea Plan.
• MSCP, City of San Diego Subarea Plan.
• MSCP, County of San Diego Subarea Plan.
• Mission View Estates.
• Orange County Southern Subregion NCCP/HCP.
• SDG&E.
• Western Riverside MSHCP.
The CNPS identifies thread-leaved brodiaea as rare, threatened, or endangered in
California and elsewhere (List 1B), and seriously endangered in California (Threat Code1)
(CNPS 2008).
MCBCP Status
Camp Pendleton is in consultation with USFWS regarding monitoring and management of
upland habitats and species basewide including thread-leaved brodiaea. The Base has
instituted measures for avoidance and minimization of impacts to rare plant locations
basewide, including thread-leaved brodiaea habitat. These measures are published as
programmatic instructions for users and residents of the Base via Camp Pendleton’s Base
Order P3500.1M (Range and Training Regulations). Management details, survey
information, etc., for thread-leaved brodiaea are located in Appendix F, Section F.21.
