This is a planned 5-year study. The purpose of this study is to: 1) Determine whether there has been further recovery of CAGN in areas burned in 2003 (i.e., occupancy greater than 10%). 2) Determine if there is a difference in CAGN occupancy between areas burned in 2003, 2007, and 2014. 3) Determine the relationship between CAGN occupancy and vegetation composition, cover and structure. 4) Determine the composition, cover, and structure of CSS vegetation in areas with different fire histories and evaluate patterns of vegetation recovery based upon lime since fire, spatial distribution, previous land use, and environmental conditions.

California Gnatcatchers will be surveyed using the wandering transect method, where we cover a 2.25 ha plot by walking slowly and methodically through the sage scrub habitat, looking and listening for gnatcatchers. The California Gnatcatcher Regional Sampling Program includes collection of vegetation covariate data to better understand gnatcatcher habitat relationships and management needs across conserved and participating military lands in southern California.
