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