Do you like observing nature? Make your observations count! The City Nature Challenge is a friendly worldwide competition among metro areas to see whose residents can spot and identify the most wildlife. We’ll be looking for signs of life in local parks, neighborhoods, and backyards to see what plants and animals share our environment. Join the City Nature Challenge and become a citizen scientist!
Why participate?
It’s fun—and it’s a great reason to spend some time with nature. You’ll help scientists collect valuable information on urban biodiversity. And you’ll help the Washington DC metro area find as many species as possible! See what we found in 2021!
Who is eligible?
Everyone in the metropolitan area with access to a camera and the internet can participate.
Where do I participate?
Please observe local travel restrictions and all local park closures. Our geographic horizons are temporarily closing in, but iNaturalist can help you become more observant and knowledgable about nature in your neighborhood, yard and home.
