About the City Nature Challenge, held April 27-30,2018

Citynaturechallengemap BoxWe need people (i.e. you) to help us take observations (e.g. taking photos with your phone) of as many species as possible to record nature in and around Boston. All species count! This information will help create a more accurate picture of the Boston area's biodiversity, focusing within the I-495 corridor and out to Stellwagen Bank. Any observation of plants, animals, fungi, even microbes, in the greater Boston area made during these days will count for the challenge. Scroll down for tips and resources on how you can help.

The Boston Area City Nature Challenge (CNC) is a collaborative project.  Learn more about our effort.
