Some of the early efforts to preserve open space for the physical and spiritual benefits offered by access to nature came from private organizations. Mount Auburn Cemetery was the first large-scale designed landscape open to the public in North America and as such began the rural cemetery movement that later led to public parks. In 1853 the Laurel Hill Association was founded in Stockbridge, inspiring a national Village Improvement Society movement. Later generations have benefitted from the first private, statewide conservation and preservation organization, The Trustees of Reservations. Historic New England has saved traditional farms and Mass Audubon and other private organizations preserve and manage open space across the state. How common is this preservation by private organizations? How sustainable is this concept for future generations?
