Shackleford Banks, part of the Cape Lookout National Seashore, is a 3,000-acre uninhabited island near Atlantic Beach. A herd of 112 wild horses lives there, one of only a few wild herds remaining in the country. The herd's reproductive rate is carefully controlled to keep the horses from putting a strain on the island's food and water resources. To understand how the horses thrive and survive in the island's harsh environment, the National Park Service has undertaken a study of the horses' eating habits. The study will look at seasonal eating habits and whether different habitats provide different nutritional contents. No findings have been reported as yet, and the study will take another year to complete.
