Welcome! MassMammals Watch is a Citizen/Community 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 submitting data/pictures of animal sightings from walks or trail cameras, or by simply helping us spread the word! Learn more about our project and how to get involved.


For regular updates about our project, sign up for our monthly newsletter! You can also follow us on Instagram and Facebook @MassMammalsWatch.
