Biogeographic Data Branch

Good management of scientific data is a critical issue for the Department. The Biogeographic Data Branch (BDB) performs a leadership, policy and standards setting role for biological and geographic data management activities for the entire Department, its contractors, and partner organizations.

BDB provides GIS support for all CDFW branches. This structure facilitates inter-branch teamwork and GIS workload balancing as changing conditions warrant.

BDB contains biological data development programs that are especially dependent and closely linked with GIS and emerging related technologies. These data development activities include vegetation mapping, rare species tracking, species range mapping, aggregation of existing incongruent data sources and decision support systems. [more]
