Join us for the 2024 City Nature Challenge in San Diego County, April 26-29! From our deserts and mountains to our wetlands and beaches, and from your backyard to your favorite local preserve, we'll look, listen, and document our county's abundant and diverse nature. Participating is easy: just make observations of plants, animals, and fungi anywhere in San Diego County from April 26-April 29, and they'll automatically be added to this project. Check back in the Project Journal for information about CNC events that you can join!
