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.
