One more thing, tell me the part about wild horses not having natural predators, again.
Further complicating the situation, livestock, wildlife, recreational users, and extractive industries, such as timber harvesting and mining, also compete for useof the land. Wildlife populations are kept in check through natural predators and hunters. Livestock populations are controlled by federal land managers through limits established in permits issued to ranchers. But controls on wildlife and livestock numbers do not apply to wild horses and burros. They are protected legally from human hunters and have few natural predators. In the absence of these checks, wild horse and burro populations increase, on average, about 15–20 percent each year.
Of course as the reintroduction of wolves move further and further south into "wild" horse areas their predation will increase.
