City Nature Challenge

Help us record New York City's flora and fauna during this year’s City Nature Challenge from April 25 - May 4, 2025! The City Nature Challenge is an international effort for community scientists and nature enthusiasts to come together and help find and document urban biodiversity. Over 400 cities across the world collaborate in this annual event with the goal of making the most observations of nature, finding the most species, and engaging the most people.

Join the City Nature Challenge by participating in one of our upcoming City Nature Challenge events! Want to participate on your own? Visit the City Nature Challenge's website to learn more.
