The National Wildlife Refuge System, managed by the U.S. Fish and Wildlife Service, is the world's premier system of public lands and waters set aside to conserve America's fish, wildlife and plants. Since President Theodore Roosevelt designated Florida's Pelican Island as the first wildlife refuge in 1903, the System has grown to more than 150 million acres, 555 national wildlife refuges and other units of the Refuge System, plus 38 wetland management districts.
