The original source of the animals is unknown. However, many of the horses in the Swasey Herd are descendents of horses that were turned loose or escaped from local ranches. 

The Swasey Herd is dominated by gray and light colored horses. Other colors include black, brown, bays, buckskins, and pintos. The average size of herd adults is 14 to 14 1/2 hands. The BLM management goal for this herd is to maintain a herd size between 60 and 100 head.

BLM Herd Management Areas

In 1971, Congress passed legislation to protect, manage, and control wild horses and burros on the public lands. The Wild Free-Roaming Horse and Burro Act declared these animals to be "living symbols of the historic and pioneer spirit of the West."

Congress further declared that "wild free-roaming horses and burros shall be protected from capture, branding, harassment, or death..." and that they are "...an integral part of the natural system of the public lands." Furthermore, Bureau regulation requires that wild horses and burros be considered comparably with other resource values within the area.

The Bureau of Land Management maintains and manages wild horses or burros in "herd management areas" (HMAs).
