Citizen Science

Want to explore the natural world and simultaneously contribute to science? Then join the global community science movement. Nat scientists, independent naturalists, and outside organizations have created numerous projects aimed at helping scientists better understand our world.

These projects use iNaturalist, a free website and app, that enables anyone with a computer or smart phone to document plants and animals. You can contribute without leaving the comfort of your own home.

Don't recognize something you've seen? That’s OK, because when you share a photo to iNaturalist, fellow nature lovers can help you ID it.

If you have plant or animal expertise, you can view and identify natural history observations from around the world without leaving the comfort of your home. It’s like a crowd-sourced way to determine what lives where.

Get started with our quick guide to iNaturalist (PDF). Most of these projects occur year round–you can join at any time.

Snapshot Cal Coast 2020

June 1-June 16, 2020

Border BioBlitz 2020

Due to health concerns, public events were unable to occur during the 2020 Border BioBlitz. When social distancing permitted, participants were encouraged to make observations of wildlife along the U.S.–Mexico Border. Despite these unforeseen circumstances, inspired citizens were able to document over 4,500 observations of diverse wildlife in our borderlands. Learn more.

City Nature Challenge 2020

The 2020 City Nature Challenge was a worldwide collaboration to collectively celebrate the healing power of nature. In only four days, over 41,000 individuals made over 815,000 observations of more than 32,500 species—including more than 1,300 rare/endangered/threatened species. In San Diego, 920 observers, spotted 2,409 species in 17,213 observations, placing us at the top of the list across the globe in regions with similar arid climates.
