The Conservation Analysis Unit (CAU) develops and maintains spatial data and models of wildlife movement, corridors, and habitat connectivity across California. These maps and models are used by scientists and decision-makers to inform how to best conserve habitat connectivity, or the ability of species and ecological processes to move through the landscape. Major projects undertaken by the CAU include 1) development of wildlife movement corridor models based on GPS collar data; 2) facilitating the development of regional, fine-scale connectivity models to identify focal species-based habitat linkages in each region of the state; 3) compilation of existing habitat linkage data from multiple sources across the state into a single statewide Terrestrial Habitat Connectivity map; and 4) identification of major barriers to wildlife movement across the state.
Information on CAU connectivity projects is summarized in the tabs below. For an overview and links to connectivity work conducted by other CDFW programs, visit the CDFW Science Institute Habitat Connectivity webpage.
The spatial data developed by CAU scientists is available for viewing and download in the CDFW spatial data library: the Biogeographic Information and Observation System (BIOS). The primary BIOS Viewer can be launched from the first button below. Additional configurations of BIOS have also been organized with select data layers on particular topics or projects preloaded in the table of contents. These are accessible through additional buttons below.
