AbstractUsing ArcGIS for Avian Conservation on Camp Pendleton, CaliforniaTrack: Ecology and Conservation Author The California gnatcatcher (Polioptila californica californica) is a federally-listed threatened species and the coastal cactus wren (Campylorhynchus brunneicapillus couesi) is a California Species of Special Concern. Geographic methods were used to analyze the distribution of the coastal cactus wren and coastal California gnatcatcher populations within the boundary of Marine Corps Base Camp Pendleton, California. This study examines these species on part of the Base, approximately 101, 606 acres in area. Two objectives of this research were to identify the distribution of suitable habitat for both species and to identify core habitat areas and possible restoration and reintroduction sites for both species. These objectives were studied through habitat suitability modeling using ArcGIS ModelBuilder, and the identification of core habitat areas was determined using Kernel Density Estimation. This research supports the regional conservation effort in southern California for the coastal cactus wren and the coastal California gnatcatcher.
