Wertheim National Wildlife Refuge

Fish and Wildlife Service, New York.

Established in 1947, Wertheim National Wildlife Refuge protects 2,550 acres on the south shore of Long Island. The refuge is bisected by the Carmans River, a New York state designated scenic river and one of the largest rivers 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. Wertheim is also home to the refuge complex headquarters and visitor center.
