The Mianus River Gorge, Inc. is a private, not-for-profit nature preserve and conservation organization. We protect and manage over 1,100 acres of land in the Mianus River Watershed. The protected lands provide habitat for hundreds of species of animals, plants, and fungi, as well as important microbes in the soil and water. Land in the Mianus River Gorge surrounds the Mianus River and its tributaries, which run directly into the Samuel J. Bargh Reservoir. The ecosystem processes occurring here help maintain clean, abundant drinking water for over 130,000 people in Greenwich, Stamford, CT, and Rye, Rye Brook, and Port Chester, NY.
To better understand the ecosystem of the Gorge and the larger region we live in, the Gorge maintains an ambitious research and education program. Their work, supported by a network of donors, research and education institutions, and partner organizations helps inform better management and conservation decisions.
The Mianus River Gorge as an organization has adopted the philosophy of land management. In the face of numerous negative impacts, it is not enough to simply protect land — one must also conduct management actions to offset negative impacts and endeavor to improve ecosystem health or function.
The 22-mile Mianus River runs through the Mianus River Gorge Preserve and is part of a 42-square mile watershed, spanning five towns in two states. MRG protects the land that encompasses the Mianus River Watershed through acquisitions or gifts of land and managing conservation easements.
