Welcome to the
2018 City Nature Challenge!

Over 60 cities will be competing to see who can make the most observations of nature, find the most species, and engage the most people in the worldwide 2018 City Nature Challenge. 

The 2018 City Nature Challenge will take place in two parts

Taking pictures of wild plants and animals

Identifying what was found

Thousands of people from across the globe will get outside to look for nature in their cities! Results will be announced on Friday May 4th. Will your city win?
