Cumberland Island Horse

The Cumberland Island horses are a band of feral horses living on Cumberland Island in the state of Georgia. Popular myth holds that horses arrived on the island some time in the 16th century with the arrival of the Spanish conquistadors. However, it is unlikely that any horses left by the Spanish survived, and more likely the current population descends from horses brought to the island in the 18th century by the English. Cumberland Island became part of the Cumberland Island National Seashore in 1972, when the National Park Service (NPS) took over its management. These horses are similar to the bands of horses living on the islands of Chincoteague and Assateague. There is estimated to be a population of between 150 and 200 horses on the island. Horses on Cumberland Island have a relatively short life expectancy, due to pest infestations, disease and their rugged environment. In 2000 a behavioral study found that instability marks the bands, with large numbers of co-dominant stallions, early dispersal of juveniles, and frequent band-changing among mares.

The herd has been studied periodically since the late 1980s, with researchers recommending various management strategies depending on the focus of their study. Current herd levels have been shown to have a negative effect on their environment, and researchers focused on environmental issues recommend a severe reduction in herd numbers. Other researchers, looking at genetic variability, state that a herd size nearly as large as current is necessary to prevent inbreeding, but also state the herd is not genetically unique enough to warrant special preservation. The National Park Service has no current management plan for the horses, and their one effort to create one was blocked by Jack Kingston, a Georgia member of the US House of Representatives.
