Celebrate California Biodiversity Day 2020 by exploring your local environment!

From September 5–13, get outside (safely!) and explore the nature around you—in your backyard, neighborhood, local parks, and open spaces—and share your findings on iNaturalist. No matter where you are in California, you can contribute to citizen science!

Please note: Your safety is our priority. Please follow all health and safety guidelines provided by the public health authority in your area as you explore outdoors. And always remember the Three Ws: Wear a mask, Wash your hands, and Watch your distance! 

As a global biodiversity hotspot, California has an immense array of nature to explore. We've compiled a few resources to guide folks in learning more about the nature around them, while contributing valuable data that can be used to answer important local conservation questions. 

During these uncertain times, we hope you're able to explore the nature around you however possible, whether that's walking to a nearby park, observing the birds outside your window, or looking for spiders under your couch. Help celebrate California's biodiversity by taking a closer look at nearby nature and documenting your finds on iNaturalist!
