Join us for the 2025 San Diego County City Nature Challenge!
On the land, in the sky, and in our waters, and from your backyard to your favorite local preserve, we'll look, listen, and document our county's abundant and unique biodiversity.
It's easy to participate! Download the iNaturalist app to your mobile device (it's free!). Then, find wildlife, take a picture (or a sound recording), and share it on iNaturalist. That's it!
