Boston Area City Nature Challenge 2026
Embedded Files
The City Nature Challenge is a fun worldwide collaborative bioblitz with cities across the world to observe the most species (April 24 – April 27) and then ID them (April 28 – May 10)! 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!
