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
A lone trillium, MRGP
It is our mission to preserve, protect, and promote appreciation of the
natural heritage of the Mianus River Gorge and the quality of its watershed
