Wertheim National Wildlife Refuge

The Wertheim National Wildlife Refuge is located on the south shore of Long Island and is one of the undeveloped estuary systems on Long Island. In 1947, Maurice Wertheim donated 2,000 acres (8.1 km2) on eastern Long Island to the United States government; the donated land subsequently became the Wertheim National Wildlife Refuge. The refuge's purpose is to protect the Carmans River Estuary for migratory birds. 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.
