The Trustees is Massachusetts' largest conservation and preservation organization and the first land preservation non-profit of its kind in the world. Founded by open space visionary Charles Eliot in 1891, we conserve some of the best of Massachusetts' natural, scenic, and cultural sites for the public to use and enjoy. We have held our "reservations" in "trust" for 126 years and believe in protecting the irreplaceable for everyone, forever. Today, we care for 116 spectacular and diverse reservations spanning more than 27,000 acres throughout the Commonwealth - from working farms, landscaped and urban gardens, and community parks, to barrier beaches, forests, campgrounds, inns, and historic sites, many of which are National Historic Landmarks - located within minutes of every resident. In addition to our properties, we are an active leader in land conservation and have served as a model for hundreds of land trusts across Massachusetts.
