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.

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, September 30: San Bruno Mountain Bioblitz

San Bruno Mountain

Join San Mateo County Parks, Sequoia Audubon, the Santa Clara Valley Chapter of the California Native Plant Society, and the California Academy of Sciences as we bioblitz the lower slopes of San Bruno Mountain! This will be a two-part blitz, with a follow-up in March to do the summit and upper reaches of the park. There are many unusual plants and animals on the slopes of San Bruno Mountain; this time was also picked for its potential for fall bird migration.
