Boston Area City Nature Challenge 2024

The City Nature Challenge is a fun worldwide collaborative bioblitz with cities across the world to observe the most species (April 26 - April 29) and then ID them (April 30 - May 6)! We'll be documenting urban biodiversity within the I-495 corridor, out to Stellwagen Bank, including Cape Cod and islands. It’s simple, it’s fun, and it contributes to scientific data helping to better understand our world and our non-human neighbors!

Here's how to Join the Boston Area City Nature Challenge:

Step 1: Download the iNaturalist app and create an account.
