Macomb Reservation State Park occupies land previously used as a military training facility. New York State purchased 6,372 acres (25.79 km2) of federal property in April 1947, 600 acres (2.4 km2) of which were given over to the New York State Office of Parks, Recreation and Historic Preservation in 1968. The remainder of the purchased property is managed by the New York State Department of Environmental Conservation for the purpose of reforestation.[3]
