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

Snapshot Cal Coast logo

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!
