High Quality Content by WIKIPEDIA articles! The Nokota horse is a feral and semi-feral horse breed located in the badlands of southwestern North Dakota in the United States. The breed developed in the 19th century from foundation bloodstock consisting of ranch-bred horses produced from local Indian horses mixed with Spanish horses, Thoroughbreds, harness horses and related breeds. The Nokota was almost wiped out during the early 20th century when ranchers, in cooperation with state and federal agencies, worked together to reduce competition for livestock grazing. However, when Theodore Roosevelt National Park was created in the 1940s, a few bands were inadvertently trapped inside, and thus were preserved. Today, the park conducts regular thinning of the herd to keep numbers between 70 and 110, and the excess horses are sold off. In the late 1970s, brothers Leo and Frank Kuntz began purchasing the horses with the aim of preserving the breed, and in 1999 started the Nokota Horse Conservancy, later beginning a breed registry through the same organization. Later, a separate breed registry was begun by another organization in Minnesota.
