Biogeographic Information and Observation System (BIOS)

BIOS is a system designed to enable the management, visualization, and analysis of biogeographic data collected by the California Department of Fish and Wildlife and its Partner Organizations. In addition, BIOS facilitates the sharing of those data within the BIOS community. BIOS integrates GIS, relational database management, and ESRI's ArcGIS Server technology to create a statewide, integrated information management tool that can be used on any computer with access to the Internet. For additional information about the CNDDB and Spotted Owl Observations Database, visit their web pages.

Please note that BIOS 5 will no longer be available starting January 2023 as we fully transition to BIOS 6. Please share with others that may need to know this information. A full BIOS 6 User Guide (PDF) is available for use, as well as a condensed version of basic functions to get started (PDF). If you have questions about BIOS 6, you can submit them to BIOS@wildlife.ca.gov.
