Welcome! MassMammals Watch is a Citizen Science project in collaboration with Amherst College. Volunteers across the state contribute valuable information which is used to track mammal populations across Massachusetts. You can contribute by sending in sightings from walks or from trail cameras. Learn more about our project and how to get involved.
