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, March 25: Junipero Serra Park
Junipero Serra Park

Join San Mateo County Parks, the Sequoia Audubon Society, and the California Academy of Sciences for a bioblitz at Junipero Serra Park! Nestled behind the cities of Millbrae and San Bruno, Junipero Serra Park affords a spectacular panorama of the Bay Area with unequaled views to San Bruno Mountain, San Francisco Airport, San Francisco Bay and Mount Diablo. Visitors are drawn to the oak foothill plant community, spring wildflowers, El Zanjon Creek, and the peacefulness of the park.

Saturday, April 1: Pier 94
Pier 94

Join Golden Gate Audubon and the California Academy of Sciences in bioblitzing this hidden gem along the bay in southeast San Francisco! Nature—with the help of hardworking Golden Gate Audubon volunteers—is reclaiming a hidden wetland consisting of nearly five acres of isolated industrial land near Pier 94 on San Francisco’s southern waterfront. Located in the shadow of container ships and heavy equipment, the restored salt marsh and adjacent upland provides valuable habitat for birds, butterflies, and small mammals.

April 14-17: City Nature Challenge
City Nature Challenge

The City Nature Challenge is back! We had such a great time last year with San Francisco vs Los Angeles that we're doing it again - but this time with cities across the United States joining in!

More information coming soon - be sure to check back here!

Saturday, April 29: UCSC Campus Bioblitz
UCSC campus

Join staff from the UCSC Natural Reserves, Ken Norris Center for Natural History, the California Academy of Sciences, legions of enthusiastic UCSC students & alumni, and members of the Santa Cruz community as we come together for a full day exploring and documenting this campus's incredible biodiversity. UCSC's wide variety of habitats and unique geophysical setting have resulted in a great number of species that call campus home. Younger Lagoon Reserve, on the marine science campus at Long Marine Lab, will concurrently host a bioblitz from 9 am-12 pm.

Registration up soon!

Saturday, April 29: Younger Lagoon Reserve Bioblitz
Younger Lagoon

Join staff from the UCSC Natural Reserves, Ken Norris Center for Natural History, the California Academy of Sciences, legions of enthusiastic UCSC students & alumni, and members of the Santa Cruz community as we come together for a morning exploring and documenting Younger Lagoon Reserve's incredible biodiversity. One of the few relatively undisturbed wetlands remaining on the California Central Coast, the Younger Lagoon Reserve encompasses a remnant Y-shaped lagoon on the open coast just north of Monterey Bay. The lagoon system provides protected habitat for 100 resident and migratory bird species. The Campus Natural Reserve will concurrently host a bioblitz from 9 am-12 pm.

Registration up soon!
