Please join our Cleveland-Akron-Canton-Toledo Team for the 2025 City Nature Challenge.

We are pleased to announce our region will participate in the City Nature Challenge from April 25-28, 2025. Cities around the world will compete to see which can document the most biodiversity in a single long weekend. This year marks the 10th year anniversary of City Nature Challenge and its tagline is Bringing the Globe Together for Biodiversity. Detailed results from each participating city/region will be announced on Monday May 5, 2025.
