Seatuck National Wildlife Refuge was acquired in 1968 as a donation from the Peters family. The refuge, located in Islip on the south shore of Long Island, consists of 209 acres bordering the Great South Bay, and is separated from the Atlantic Ocean by Fire Island. With its diverse mix of upland and wetland habitat types, Seatuck hosts more than 200 bird species, and serves as an oasis in a heavily developed urban area. This refuge is NOT open to the public. A special use permit can be acquired for select activities (e.g. biological research, environmental education) by contacting the refuge.
The Long Island National Wildlife Refuge Complex consists of seven national wildlife refuges, two refuge sub-units and one wildlife management area. Collectively, the ten units are approximately 6,500 acres in size. Wertheim National Wildlife Refuge is home to the refuge complex headquarters and visitor center.
