With nearly 7,000 preserved acres, the Mohonk Preserve is the largest member-supported nature preserve in New York State, and protects an important swath of ridgetop land at the northern end of the Shawangunk Mountain.
OSI is working closely with the Mohonk Preserve on three important expansions of the Preserve. The first of these areas is an extension of the Mohonk Preserve northwards towards the hamlet of Rosendale, and protecting the very northern reaches of the range and the ecologically unique area north of Bonticou Crag. The second effort involves acquiring lands in the area of the Peterskill, just north of the High Peterskill entrance to Minnewaska State Park Preserve. The third important expansion of the Mohonk Preserve involves 857-acres of scenic lands and farms on the eastern escarpment of the Shawangunk Ridge, near the Village of Ne Paltz, that was acquired from Smiley Brothers, Inc., the owners of famed Mohonk Mountain House.
