Public BIOS Data Layers

Biogeographic Information and Observation System (BIOS)

This is a list of the public GIS datasets available in CDFW's BIOS web mapping application. A large majority of the datasets in BIOS are available to the public.

If you've arrived here from a web search, please go to the BIOS home page to launch the BIOS application and then find the data you're interested in.

Contact the BIOS Staff — if you have any questions.
