California Biodiversity Day is September 7th, and we are celebrating all week from September 2nd – 10th! Explore nature in your local neighborhoods and parks or join one of the over 100 in-person and virtual CA Biodiversity events. See below for event information and check out this map to find an event near you! Don’t forget to use the hashtag #CABiodiversity to share your biodiversity day adventures.
An easy way to celebrate is to get outside and contribute to our collective knowledge about California’s biodiversity through the nature-mapping platform, iNaturalist. Nature-mapping contributes to California’s 30x30 initiative, which aims to conserve 30% of California lands and coastal waters by 2030 through collaborative action.
Participating is easy: 1. Join iNaturalist and download the app. 2. Follow directions from this short video describing how to make and submit an observation. 3. Find a nature-mapping event (aka a “bioblitz”) near you or join in the week-long CA Biodiversity Nature Challenge from anywhere in California. Once you sign into iNaturalist, join the challenge, and submit your observations between September 2 to 10! Can you find 30 wildlife species for CA 30x30? 4. Have fun!
