Are wild horses responsible for overgrazing on public lands?
The main cause of degradation of public lands is livestock use, not wild horses. Cows graze within a mile of water, while wild horses are highly mobile, grazing from five to ten miles from water, at higher elevations, on steeper slopes, and in more rugged terrain. A congressionally-mandated study by the National Academy of Sciences found that, in one year, livestock consumed 70% of grazing resources on public lands, while wild horses and burros consumed less than 5%.
