Arrowhead Ranch Pryor Mountain Mustangs


On one of our first visits to the Pryor Mountain Wild Horse Range in 1998, we had seen 15-20 separate family groups, each with a head stallion and several mares & foals. Wondering throughout would be several bachelor groups averaging 3-5 horses getting ready to challenge the stallion.

In the past, Bureau of Land Management had maintained the Pryor Mountain herd to approximately 120-160, a good amount for the area. The only source of new horses were from foals born each year.

In order to do this, the adoption program began where horses were rounded up and brought in for adoption for the public. As more horses were being brought in, then adoption called for and the escalating cost of the round up, BLM worked to develop methods to control the overload. The roundup ended and they began using PZP (Porcine Zona Pellucida), a contraceptive for the mares, which will decrease new foals being born*.

With this in place and natural predation such as the mountain lion, black bear, wolf, and coyote increasing and taking into account natural deaths by severe weather, lightning, falls and injuries, the Pryor Mountain Mustangs will eventually be decreased to a level where genetically they will no longer be, as we know them.

Add this to the round up and adoption no longer being an option, the Pryor Mountain Mustang will no longer be available to the public and the only option of keeping this beautiful rare breed going will be through private breeders, of which there are only a hand full.Our goal as a private breeder is to preserve and protect these horses and the genetic balance that now exists.

As Dale Hartman once stated: “Historically these horses are like the Black Hills, the Grand Canyon, and the Rocky Mountain Range. This is a heritage we must preserve!"
