Less than forty miles from Manhattan, the Mianus River Gorge Preserve (MRGP) remains an oasis of rich woodland and old-growth forest one hour's drive from New York City. The Preserve was established in 1953 to protect an old-growth hemlock forest and receives the special designation as the first Nature Conservancy land project and the first National Natural History Landmark designated by the US Department of the Interior.
Today, the Mianus River Gorge Preserve, Inc., is an independent not-for-profit that protects over 750 acres of land and a water supply for over 150,000 people in Connecticut and New York. Drawing on our rich history of science-based management and land conservation, we continue to be a model for the protection of rare, isolated habitat in an increasingly developed world.
Welcome
