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!

 

April 14-18: 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! There are 16 cities from Seattle to Miami, from LA to NYC, from Chicago to Houston, all taking part in City Nature Challenge 2017!

Saturday, April 15: Ring Mountain Bioblitz
Ring Mountain

In celebration of national Citizen Science Day and in support of the City Nature Challenge, join the California Academy of Sciences and Marin Country Day School in a bioblitz of Ring Mountain! The unique geology and microclimate of this location provide a home for a number of rare plants. The ridge contains serpentine soils,with isolated populations of rare plants. The most extreme example of this phenomenon is the Tiburon Mariposa Lily, which is found on the upper slopes of Ring Mountain, and nowhere else on earth.

Saturday, April 15: Edgewood Park & Natural Preserve

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.

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 Reserve encompasses a remnant Y-shaped lagoon. 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.
