MCB Camp Pendleton, California and Endangered Wildlife and Plants (USFWS 2004e). The USFWS found that the petition presents substantial information that delisting the Pacific coast population of the western snowy plover may be warranted, and initiated a status review. On 21 April 2006, the USFWS announced a 12-month finding on the petition to remove the Pacific coast population of the western snowy plover from the Federal List of Threatened and Endangered Wildlife pursuant to the ESA of 1973, as amended. After reviewing the best scientific and commercial information, the USFWS found that the petitioned action was not warranted (USFWS 2006d). However, results of the USFWS 5-year review, signed June 2006, found that the Pacific coast population constitutes a valid Distinct Population Segment (DPS) (USFWS 2006f). On 22 March 2011, the USFWS proposed to revise the critical habitat designation for the western snowy plover. All 441 ac considered for designation on Base are proposed to be exempted under 4(a)(3) of the ESA in the final rule (USFWS 2011e). California Status The western snowy plover (coastal population) is listed as a Species of Special Concern by the CDFG (CDFG 2008b). Regional Status The western snowy plover is a covered species in the following southern California NCCP documents: • Cal. Dept. of Corrections Statewide Electrified Fence Project. • Kern Water Bank. • 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. • SDG&E. MCBCP Status Protection and management of the western snowy plover and its habitat is provided for in the Estuarine and Beach Conservation Plan as an attachment to the Riparian BO signed on 30 October 1995. The Estuarine and Beach Conservation Plan is located in Appendix B and the terms and conditions to the BO are located in Appendix L. Programmatic instructions that provide basewide proscriptions for avoidance and minimization of impacts to the species and its habitat, especially during the Special Management Season, which coincides with its breeding season, are provided in the Estuarine and Beach Conservation Plan and Base Order P3500.1N (Range and Training Regulations). Management details, survey information, etc., for the western snowy plover are located in Appendix F, Section F.23. 3-52 Chapter 3 – Natural Resources
Integrated Natural Resources Management Plan [March 2012 - Update] FIGURE 3-20. SNOWY PLOVER NESTING LOCATIONS DISTRIBUTION Global The western snowy plover breeds on the Pacific coast from southern Washington to southern Baja California, Mexico, and in interior areas of Oregon, California, Nevada, Utah, New Mexico, Colorado, Kansas, Oklahoma, and north-central Texas, as well as coastal areas of Texas and possibly northeastern Mexico. The Pacific coast population of the western snowy plover is genetically isolated from western snowy plovers breeding in the interior (USFWS 1993b). The Pacific coast population of the western snowy plover is defined as those individuals that nest adjacent to or near tidal waters and includes all nesting colonies on the mainland coast, peninsulas, offshore islands, adjacent bays, and estuaries (USFWS 1993b). The coastal population of the western snowy plover consists of both resident and migratory birds; some birds winter in the same areas used for breeding (USFWS 1993b). Migratory individuals of the coastal western snowy plover travel either north or south within their coastal range. Typical breeding season occurs within its Special Management Season on Base from 1 March to 15 September. Regional The two main breeding sites for the western snowy plover in San Diego County are located at Camp Pendleton and Silver Strand (Unitt 2004). Other breeding sites include: Batiquitos Lagoon, San Elijo Lagoon, Mariner’s Point (Mission Bay), Sweetwater River Estuary, Chula Vista Wildlife Reserve, and the Tijuana River mouth (Unitt 2004). As a result of successful management on San Diego County military installations while accomplishing training missions, a majority of the western snowy plover population (approximately 65 percent) within Recovery Unit 6, which includes: Zuma Beach, Santa Monica Bay, Bolsa Chica area, Santa Ana River Mouth, San Onofre Beach, Batiquitos Lagoon, Los Penasquitos, and South San Diego are located on military installations (USFWS 2007j). MCBCP Nesting sites on Camp Pendleton include: Aliso Beach (White), Cocklebur Beach, North Beach (North), North Beach (South), South Beach, Red Beach, and Gold Beach (South) (see Figure 3-19) (Collier and Terp 2001 & Sullivan pers. comm. 2009). In 2004, the western snowy plover constructed 212 nests on Base (Foster 2006). Approximately 30 percent of the MCBCP nesting population stays over winter on Base (USFWS 2007j).
