The San Francisco Bay Area Network (SFAN) consists of eight national park units located along the central California coast. SFAN parks contain some of the most significant examples of terrestrial Mediterranean-type ecosystems and coastal marine environments anywhere in the world.

This site provides access to study results, data, and related analysis about the natural resources investigated by the SFAN network, its parks, research and land management partners. Park managers use this information make decisions about park resources.

SFAN also works closely with the San Francisco By Area National Parks and Learning Center and each park's natural resources program to develop sound scientific resources that lead to improved management and preservation.
