Massachusetts is home to a great diversity of life, from the Berkshires to Boston to the Bay. Join us for the Boston iNaturalist City Nature Challenge – a fun competition with cities across the country to document the most species during April 14-18, 2017. You can participate by joining an event or documenting the plants, animals, and fungi you see anywhere in the greater Boston area with the iNaturalist app. See the map below for the area we will cover.

Check out our calendar of events and places to explore for ideas of where and when to get outside.

We've already won the Super Bowl. Let’s keep that competitive spirit going and observe more species than any other metropolitan area!

The Boston City Nature Challenge is organized by Environmental Studies at Brandeis University, Encyclopedia of Life at Harvard Museum of Comparative Zoology, Earthwatch Institute, MIT Senseable lab, New England Ocean Science Education Consortium and New England Aquarium. less ↑
