I love the wild horses around here. I really do. Every morning I get to see them. When we go off-roading they are all over. But there are too many. So far I have only see one dead one on the side of the trail. But they breed FAST. every tiny herd around here is 1/3 to 1/2 yearlings and younger. A couple good wet years and the population explodes. One good dry year and they are going to be dying all over the place.
I live in Millard County Utah. We have an abundance of the things. Everyone I know, that knows anything about range management wants these vermin gone. They destroy the ground with every hard hooved step. When they run, it’s even worse. This isn’t some eastern pasture that gets 36 inches of rain, it’s the desert and it might get 12” in a good year. A house on that range is more destructive than a cat in the house.
