Come help the Smithsonian and the Audubon Center remove an invasive predator from Richardson Bay!

Invasive Atlantic oyster drill snails are hurting the recovery of Olympia oysters, the only oyster that is native to the West Coast. Olympia oysters used to be abundant in San Francisco Bay, but human impacts have threatened their existence here. Researchers from the Smithsonian Environmental Research Center are working with citizen scientists (that’s you!) and others on a field experiment to control Atlantic oyster drill populations in Richardson Bay. We need your help! We will be collecting the snails by hand (kids welcome, no experience necessary), having fun, getting muddy, and learning ecology.
