San Pablo Bay National Wildlife Refuge
The San Pablo Bay National Wildlife Refuge lies along the north shore of San Pablo Bay in Sonoma, Solano, and Napa Counties in northern California. The refuge includes open bay/tidal marsh, mud flats, and seasonal and managed wetland habitats.

The Napa-Sonoma marshes in San Pablo Bay have been greatly impacted by human activities such as hydraulic mining, salt production, water diversions, and diking, draining, and filling for agricultural and industrial uses. About 85 percent of the historic tidal marshes of San Pablo Bay have been altered, negatively affecting the ability of the remaining tidal marshes to accept winter rainfall and purify water in the bay.

The refuge provides critical migratory and wintering habitat for shorebirds and waterfowl, particularly diving ducks, and provides year-round habitat for endangered, threatened, and sensitive species like the California clapper rail, salt marsh harvest mouse, California black rail, San Pablo song sparrow, and Suisun shrew.

Numerous other threatened, endangered, and sensitive species require tidal marsh habitat for their survival, including 11 fish species that swim through San Pablo Bay to reach their fresh water spawning grounds.

Less than 150 years ago, the Napa-Sonoma marshes surrounding San Pablo Bay comprised one of the most extensive wetland systems along the Pacific coast. This system provided habitat for millions of migrating waterfowl and shorebirds as well as resident wildlife. Plants specialized to live in aquatic habitats grew bountifully, sheltering and feeding a rich diversity of species.

Diminishing habitat and introduced non-native plants and animals are threatening the survival of marsh-dependent species, including the endangered California clapper rail, salt marsh harvest mouse, and many rare and endemic salt marsh plants. The refuge is engaged in tidal restoration projects critical to the long-term future of these species.

Refuge objectives include protecting threatened and endangered species, providing wintering habitat for diving ducks, conserving migratory birds and other wildlife, and providing compatible wildlife-dependent recreational opportunities.

Local support for habitat conservation and research contributes to our ability to reach our objectives and restore and enhance northern San Pablo Bay lands for the benefit of wildlife and people.
