Pryor Mountain horses (Equus caballus) are one of the few feral or, more popularly, wild horse populations in the US with strong Spanish ancestries. The population is restricted to the Pryor Mountain Wild Horse Range (PMWHR), created in 1968 and includes land inside and adjacent to Bighorn Canyon National Recreation Area. The horses are protected as “living symbols of the historic and pioneer spirit of the West” under the Wild and Free-Roaming Horses and Burros Act of 1971, which requires management to achieve and maintain a “thriving natural ecological balance” on public lands used by the horses. The population is considered a unique genetic resource since horses of this type are no longer present in Spain. The horses also provide visitor enjoyment and are the subject of great public interest. The PMWHR is managed by an interagency group led by the Bureau of Land Management.
