Welcome to the
2018 City Nature Challenge!

Nearly 70 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?

Taking Part is Easy

Find Wildlife

It can be any plant, animal, fungi, slime mold, or any other evidence of life (scat, fur, tracks, shells, carcasses!) found in your participating city.

Take a Picture of What you Find

Be sure to note the location of the critter or plant.

Share Your Observations

By uploading your findings through iNaturalist or your city's chosen platform.
