A 2019 analysis by the Center for Biological Diversity of available habitat throughout the red wolf's former range found that over 20,000 square miles of public land across 5 sites had viable habitat for red wolves to be reintroduced to in the future. These sites were chosen based on prey levels, isolation from coyotes and human development, and connectivity with other sites. These sites include: the Apalachicola and Osceola National Forests along with the Okefenokee National Wildlife Refuge and nearby protected lands; numerous national parks and national forests in the Appalachian Mountains including the Monongahela, George Washington & Jefferson, Cherokee, Pisgah, Nantahala, Chattahoochee, and Talladega National Forests along with Shenandoah National Park and the lower elevations of Great Smoky Mountains National Park; Croatoan National Forest and Hofmann Forest on the North Carolina coast, and the Ozark, Ouatchita, and Mark Twain National Forests in the central United States.
