Bioblitzes: Discover Nature

Snapshot Cal Coast is an annual effort to document California's coastal biodiversity over two weeks every summer. We encourage people to make and share observations of plants, animals, and seaweeds along the California coast using the iNaturalist app. You can participate on your own, or join one of a series of coastal bioblitzes held by our partners up and down the coast! We are interested in data from any coastal influenced habitats along the California Coast, including tidepools, sandy beaches, bays, wetlands, and docks. The Academy holds events in San Mateo, Marin, and Sonoma counties, but be sure to check the main Snapshot Cal Coast page to see events along the entire coast!

In support of Snapshot Cal Coast, join us at Duxbury Reef to search for and document all the species we can find! Hidden away on the Marin coast, Duxbury Reef is the largest soft shale reef in California, and one of the largest shale reefs in all of North America! Join us for one of the best low tides of the year!

In support of Snapshot Cal Coast, join us at Pillar Point Reef to search for and document all the species we can find! Forming the famous wave of the Maverick's surf contest, Pillar Point reef is truly spectacular during low tide, home to over 500 documented species! Come see it during one of the lowest low tides of the year!

In support of Snapshot Cal Coast, join us at Muir Beach to search for and document all the species we can find! Just over the Golden Gate Bridge where Highway 1 meets the coast again is Muir Beach in Marin. It's beautiful pocket of sandy beach bookended by rocky tidepools. Join us as we explore these rocky outcrops and walk the beach to see the interesting things that have washed up!

We are lucky enough to partner with organizations who also host their own citizen science events. Check out their pages for some great upcoming bioblitzes, restoration days and more!
