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 the Bay Area for over 10 years. Explore the events we've helped host in the past here!

Check below to find out about upcoming bioblitzes and other community science events and campaigns. Links will be live once the event 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 ahead of time!

The work we do utilizes iNaturalist to make biodiversity observations while building community around nature. 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.

In the News

A selection of videos, articles, and press that offer a closer look at community science at the Academy.
