Building a Foundation for Nature Conservation

The San Francisco Bay Area Network (SFAN) is one of 32 National Park Service Inventory and Monitoring (I&M) Networks across the country established to facilitate collaboration, information sharing, and economies of scale in natural resource monitoring. SFAN consists of eight national park units located along the central California coast. These 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 and its park, research, and land management partners. Park managers use this information make decisions about park resources.
