Why participate? 

There is nature all around us, even in our cities! Knowing what species are in our city and where they are helps us study and protect them, but the ONLY way to do that is by all of us – scientists, land managers, and the community – working together to find and document the nature in our area. By participating in the City Nature Challenge, not only do you learn more about your local nature, but you can also make your city a better place – for you and other species!
