The Bureau of Land Management estimates that western ecosystems can support about 30,000 wild horses. The problem? There’s almost triple that. And that number rises by 10-20% every year. Too many wild horses – just like too many cows – is bad for the fragile, arid rangelands of the West. The horses can overgraze the native grasses and destroy creeks and riparian areas that provide critical habitat for the Greater Sage-Grouse and other creatures. To find out what this looks like on the ground, Ashley heads to Nevada, the state with the most wild horses in the U.S., and gets out in the sagebrush with biologists there. Meanwhile, back at the ranch, Ashley spends some time getting to know her skinny, scared mustang and wonders what the hell she’s gotten herself into.
