In response to public outcry about the fate of wild horses, in 1971 Congress passed the Wild Free-Roaming Horse and Burro Act declaring that “wild horses and burros are living symbols of the historic and pioneer spirit of the West; that they contribute to the diversity of life forms within the Nation and enrich the lives of the American people; and that these horses and burros are fast disappearing from the American scene.” Initially, The Bureau of Land Management (BLM) and the U.S. Forest Service (USFS) were appointed to implement the Act, but the BLM controls the herd areas and grazing issues.
Today, thirty some years later the fate of Wild Horses has not improved and is the center of controversy for cattle owners and horse owners. While the BLM asserts that the population of wild horses increases too quickly for the amount of public land available for grazing, other animal protection groups report different facts. BLM removes Wild Horses and Burros and either offers them for adoption or puts them in holding pens, to control the population.
The actual issue appears to be one of public land grazing rights. Along with its other responsibilities, BLM also issues public land grazing permits to cattle ranchers, so when a wild horse is removed from public land, a cow takes its place and a cattle rancher gets to graze his animal for a minimal cost.
