In December 2016, The Nature Conservancy donated Nellie Hill to the U.S. Fish and Wildlife Service as the first parcel establishing Great Thicket National Wildlife Refuge. Great Thicket National Wildlife Refuge spans six states, focusing on protecting and managing shrubland and young forest habitat from eastern New York to Maine. For more information on Great Thicket National Wildlife Refuge, contact Beth Goldstein at

From atop the rocky summit of a 120-foot calcareous cliff, enjoy gorgeous views of pocket grasslands that resemble savannas, sloping meadows, a rich oak woodland and a limestone woodland. Five springs burble gently through the property, and two ponds rest in the valley below. In the spring and late summer, glorious wildflowers fill the fields with color and vibrancy. Because of its varying habitats, Nellie Hill is a hotspot for migratory birds.
