Bioblitzes are gatherings of scientists, community 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!

 

 

Saturday June 26: Pillar Point tidepools bioblitz for Snapshot Cal Coast

Pillar Point tidepools bioblitz

Join us on Saturday, June 26 at 6am to bioblitz the Pillar Point tidepools for Snapshot Cal Coast! All you need is the iNaturalist app on your phone and an account made, some rubber boots (or other shoes with good tread that can get wet!) and your curiosity. We'll spend a couple hours exploring the tidepools for starfish, crabs, nudibranchs, seaweed, urchins... everything! The low tide is early but it's one of the best of the year - search carefully and you're bound to find hundreds of species!
