Shackleford Banks is the only major North Carolina barrier island that is protected as a wilderness area and prohibits vehicles. Wild horses live on the nine-mile island. Legend says the animals are descendants of horses that survived Spanish shipwrecks. They can be documented on the island for 200 years. In 1998, Congress passed legislation requiring that the herd be at least one hundred horses and be co-managed by the National Park Service and the Foundation for Shackleford Horses. Jenkins discusses how the co-management arrangement is working.
