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!
Share YOUR Nature Observations!

September 4-12, we are teaming up with the California Natural Resources Agency to celebrate California Biodiversity Day by enlisting ALL Californians in making and sharing nature observations! Download the iNaturalist app and take photos to document the nature around you!
1. Download the iNaturalist app for iPhone or Android
2. Create an account to start making observations
3. Get out in your yard, neighborhood, local park, or anywhere you find nature to make observations September 4-12.
5. Spread the word! Use our hashtag on social media #CABiodiversityDay

The work we do utilizes iNaturalist to make biodiversity observations while building community around nature. It's a community-powered website and app that makes it easy to upload and share your observations in the field and to get help from other users with flora and fauna IDs.
