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.

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.

The Boston City Nature Challenge is organized by Environmental Studies at Brandeis University, UMass Boston, Zoo New England, New England Ocean Science Education Collaborative, Mass Audubon, Encyclopedia of Life at Harvard Museum of Comparative Zoology, MIT Senseable lab, and Earthwatch Institute.
