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!
Bioblitzes are gatherings of scientists, citizen scientists, land managers, and more, all working together to find and identify as many different species as possible. Bioblitzes not only help land managers build a species list and atlas for their park and provide invaluable data for researchers, they also highlight the incredible biodiversity in these Bay Area oases.
Our bioblitzes are open to anyone and are family-friendly. Just bring your smartphone with the iNaturalist app, your curiosity, and your powers of observation to help catalog the natural wonders of our parks and open spaces.
We've been hosting grassroots bioblitzes in our community for over 5 years. Explore the events we've helped host in the past here!
Check below to find out about upcoming grassroots bioblitzes. Links will be live once the bioblitz is open for registration. Registration is free, but be sure to let us know you're coming so we can send you all the information you need prior to the bioblitz!
Snapshot Cal Coast 2019: June 1-16
Wednesday, June 5: Duxbury Reef bioblitz for Snapshot Cal Coast

Join us for one of the best low tides of the year!
Thursday, June 6: Pillar Point Reef bioblitz for Snapshot Cal Coast
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!

Sunday, June 9: Muir Beach bioblitz for Snapshot Cal Coast
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!
Our bioblitzes are powered by iNaturalist, our in-house, citizen science platform. It's a community-powered website and app that makes it easy to upload and share your observations in the field and to get help from other users with flora and fauna IDs.
