The document discusses identifying suitable habitat for the California gnatcatcher (CAGN) in Orange and San Diego Counties. It aims to qualitatively compare CAGN presence survey data to a habitat suitability model. The CAGN is used as an indicator species for coastal sage scrub (CSS) health and biodiversity conservation. CSS range was previously 90% larger but has declined due to agriculture and urban development, leading to the CAGN being listed as threatened. The study area is Orange and San Diego Counties, where suitable habitat will be identified to prioritize conservation and restoration efforts. Habitat data sources include vegetation type, gnatcatcher presence surveys, streams, fire perimeters, elevation, and slope.
