Article abstract: Goals and Objectives: In the spring of 2007, the San Diego Association of Governments (SANDAG) supported and funded the U.S. Fish and Wildlife Service (USFWS) to conduct the first comprehensive survey in San Diego County for coastal California gnatcatchers. The objectives for this project were to: 1) Provide a population estimate of gnatcatcher pairs in San Diego County during the 2007 breeding season. 2) Determine the distribution of gnatcatchers by calculating the Percent Area Occupied of habitat in San Diego County. 3) Improve the gnatcatcher habitat suitability model developed in 2002. 4) Evaluate the recolonization of gnatcatchers in habitat burned in the 2003 wildfires. 5) Explore the concept of ?extinction and colonization? of gnatcatchers in space and time.
