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.
This 2,550 acre refuge on the south shore of Long Island is bisected by the Carmans River; a New York state designated scenic river and one of the largest on the island. Wertheim hosts a variety of habitats including oak-pine woodlands, grasslands and fresh, brackish and salt water wetlands. These habitats attract and support many types of wildlife including white-tailed deer, osprey, muskrat, fox, turtles, frogs and fish. The refuge also serves as a haven for waterfowl, shorebirds, raptors and songbirds.
