City Nature Challenge
Overview & Results 
What is it?
Do you enjoy observing nature? Get outside with your friends and family and document plants, animals, and fungi for the City Nature Challenge! The Challenge is a global science event taking from April 24-27. During the City Nature Challenge, participants can observe wildlife in local parks, neighborhoods, and even their own backyards using a free, easy-to-use app called iNaturalist. Anyone can do it and you can participate anywhere—all you need is the app!
Why Participate?
The City Nature Challenge is a great reason to get outside and experience nature. Plus, your observations will help scientists understand what species share the DC urban environment and collect valuable information on biodiversity. NOVA Parks has over 30 properties that are great places to participate in the City Nature Challenge. Stop by any NOVA Parks' location and experience all the nature NOVA Parks has to offer!
