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 can I participate?

You are invited to participate in Anacostia Park, and throughout the greater Washington area.
