The Trustees is an organization with a fascinating past and an exciting future. Our places are open to all and we thrive by involving as many people as possible in what we do. Founded in 1891, by a group of visionary volunteers, we preserve, for public use and enjoyment, properties of exceptional scenic, historic, and ecological value in Massachusetts and work to protect special places across the state. We have helped protect more than 50,000 acres, including 25,000+ acres on 116 reservations that are all open to the public. We are a nonprofit conservation organization funded and supported entirely by our visitors, supporters, volunteers, and more than 50,000 members.
