Put Memphis on the map
Memphis needs you to help document our biodiversity! The City Nature Challenge is a friendly international competition to see which cities can document the most wildlife in a single weekend. This year, you can help us put Memphis on the map. Join Overton Park Conservancy and other local organizations for a weekend of fun nature-focused events, or use iNaturalist to record wildlife observations on your own!
The observation period for the 2026 City Nature Challenge will be held from Friday, April 24 to Monday, April 27. The identification period will last through May 10, and final results will be announced on May 13.

Support Nature Education
Overton Park Conservancy has been stewarding Memphis’s central green space since 2012. Programs like our City Nature Challenge events are only possible thanks to community donations.
Each year, we raise 90% of our budget through the generosity of individuals who value the park’s natural and educational resources.
