The dominant colors of the horses within the herd area are black, buckskin, grulla, and bay in that order. The dominant colors of the burros within the herd area are black and gray. The horses on the HMA are average in size ranging from 700 to 1000 pounds. The BLM management goal is to manage the horse herd at near 50 head and the burros at near 75 head. In order to achieve this goal, some of the horses and burros must be rounded up every 2 to 5 years. Excess animals are then offered for adoption through the BLM’s wild horse and burro adoption program.
