City Nature Challenge S.F. vs L.A.

April 14, 2016 - April 21, 2016


San Francisco Bay Area: let’s #BeatLA! The biodiversity challenge is on! We know how beautiful and full of nature the Bay Area is, from our city, county, state, and national parks, to the nature in our own backyards and sprouting in the cracks of the sidewalks. Help us document the Bay Area’s biodiversity!

Along with making observations where you are, feel free to sign up for our McLaren Park bioblitz on Saturday, April 16, where we’ll all come together to document as many species as possible in the park!


What better way to help create a baseline of California biodiversity than to capitalize on the friendly rivalry between San Francisco and Los Angeles and engage in a biodiversity competition? Centered around National Citizen Science Day and Earth Day, the California Academy of Sciences and the Natural History Museum of Los Angeles County are asking residents of and visitors to the San Francisco Bay Area and Los Angeles County to explore nature all around them and document the species they find using iNaturalist. At the end of the week, we’ll compare stats like total number of species found, total number of observations, and total number of observers to find out who comes out on top: Los Angeles or San Francisco!

This is the page for nature observations in the San Francisco Bay Area for the City Nature Challenge, you can also see what’s being observed in Los Angeles County here:
