Why are mudflats important?

San Francisco Bay’s mudflats support millions of migratory shorebirds — the bay is the most important shorebird staging area on the Pacific coast. Tiny invertebrates in the mud provide critical fuel for birds traveling thousands of miles. Over 70% of the bay’s original wetlands have been filled — remaining mudflats are irreplaceable.

About Emeryville Crescent

Emeryville Crescent protects a 29-acre tidal marsh along San Francisco Bay — one of the last remnants of the vast tidal marshlands that once ringed the Bay. The marsh is critical habitat for endangered California clapper rail and salt marsh harvest mouse.

Things to Do

Birdwatching from the Bay Trail (clapper rail most vocal during breeding season), photography, and interpretive walking. The Emeryville Marina and Bay Trail offer miles of paved paths with stunning Bay and SF skyline views.

Bay views: The waterfront offers postcard views of the Bay Bridge, San Francisco skyline, and Alcatraz.
