\"Back<\/a>Busby Biological Services, Inc. (BBS) is currently entering the final\u00a0data review and reporting stage for the “Coastal California Gnatcatcher 2014 General Inventory and Breeding Status Assessment Study on Marine Corps Base Camp Pendleton, California”. This marks the second\u00a0time that BBS has participated in\u00a0this\u00a0large scale, Basewide study; the first was during 2010.<\/p>\n

The objectives of this study were\u00a0to conduct a habitat assessment to identify potentially suitable\u00a0Coastal California Gnatcatcher (CAGN) breeding habitat, to conduct a presence\/absence survey for CAGN, and to monitor a target of 50 CAGN\u00a0nests\u00a0to assess survival and productivity within the approximately 125,000-acre base.\u00a0BBS served as the technical lead for this study retained by Tetra Tech Inc. \u00a0The survey team was composed of\u00a0U.S. Fish and Wildlife Service (USFWS)-permitted CAGN surveyors and nest monitors primarily from BBS and the San Diego Natural History Museum (SDNHM), as well as other USFWS-permited independent biologists.<\/p>\n

The project began during the fall of 2013 with\u00a0a pre-breeding habitat assessment of approximately 45,000 acres of potentially suitable CAGN breeding habitat identified from\u00a0Base Geographic Information System (GIS) vegetation map layers. During the habitat assessment, the\u00a0potentially suitable CAGN breeding habitat was further refined to identify approximately 20,000 acres that would require\u00a0presence\/absence surveys and nest monitoring for CAGN.<\/p>\n

The CAGN surveys and nest monitoring were\u00a0conducted during a 5 month period between approximately February 15 and\u00a0July\u00a015, 2014. All surveys were conducted according to the USFWS Coastal California Gnatcatcher Presence\/Absence Survey Protocol for participants in the Natural Communities Conservation Plan (NCCP), requiring no more than 100 acres of suitable habitat be surveyed per day during three replicate surveys of each\u00a0area. CAGN nests\u00a0were monitored temporally and spatially on Base to assess survival and productivity. Nest data were analyzed using the Mayfield method for calculating nest success, which\u00a0uses the period of time a nest was observed and the time of exposure to loss to calculate nest survival.<\/p>\n

The Base has been conducting these CAGN surveys since 1989 and Basewide surveys are conducted approximately every three to four years. Results from this Basewide survey effort aid the Base in supporting natural resource conservation; compliance with federal, state, and local statutes and regulations;\u00a0military readiness activities; and with Department of Defense policies, instructions, and guidance.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
