Audubon California has long been committed to protecting the birds and habitat of the San Francisco Bay and its wetlands.
The San Francisco Bay area is recognized as an international biodiversity hotspot because of the vast number of species of birds, animals, plants found there – many of which are found nowhere else. The bay itself is the largest estuary on the West Coast, and is considered one of North America’s most important. It provides critical habitat for shorebirds, waterfowl, marsh birds, as well as over 500 species of fish, mammals, and plants, many of which are either threatened or endangered.
San Francisco Bay is a critical stopover point along the Pacific Flyway migration route of shorebirds and waterfowl, which number over one million birds at the height of migration, and includes three Important Bird Areas due to the high number of rare and endangered bird species and the sheer number of shorebirds and waterfowl supported by the by and surrounding wetlands. The area has also been recognized by the Western Hemisphere Shorebird Reserve Network, which ranks it as being of “Hemispheric Importance” to shorebirds.
Audubon California operates the largest estuarine reserve in San Francisco Bay, the Richardson Bay Audubon Center & Sanctuary, which protects 900 acres of San Francisco Bay habitat and provides a center for community education, restoration, and celebration of the Bay.
The Richardson Bay Audubon Center & Sanctuary is a remarkable slice of nature on the shores of the San Francisco Bay.
Audubon is advancing nature-based strategies to help coastline communities weather the impacts of climate change.

This large, handsome shorebird is often seen on our coast, calling in loud springtime territorial displays, hunkered together in small winter flocks and prying limpets off rocks. Yet the species is rare across its range and poorly understood in California in particular.

Staff from Audubon California today led a birding walk with Congressman Jared Huffman and Marin County Supervidor Damon Donnolly at China Camp State Park. Audubon joined with the National Estuarine Research Reserve to talk about how wetlands provide climate resiliency, biodiversity, and recreational opportunities.
The story of the Richardson Bay Audubon Center & Sanctuary is an amazing tale of of a community rising up to defend a natural treasure in their community. With the Center's 60th anniversary, Audubon created this great video reviewing the history of the place, and what it portends for the future.

November marks the 10-year anniversary of the Cosco Busan oil spill in San Francisco Bay. With that in mind, we recently revisited our restoration project on Aramburu Island in Richardson Bay that was largely inspired by the disaster. We're happy to report that the birds are responding well to the newly created habitat.
