San Francisco Bay Area National Parks encompass a staggering diversity of ecosystems. Situated in one of the most biologically rich areas in the world, the parks include open ocean and rocky intertidal zones, brackish estuaries and wetlands, and freshwater streams and ponds. On land, habitats include everything from sandy beaches and dunes to grasslands, scrub, and forests, to caves and high rocky spires.

-
Rivers & Streams
In an arid, Mediterranean climate like that of the San Francisco Bay Area, rivers and streams provide corridors of precious water.

Wetlands and estuaries provide some of the most fertile habitats on Earth.
