City Nature Challenge

Cleveland is once again participating in the Nature City Challenge on April 30-May 3, 2021. Cities around the world compete to see who can document the most biodiversity in a single long weekend. The number of observations, the number of species identified and the number of people participating are shared and compared. Join the Cleveland-Akron-Canton team today!
