Horses evolved in the North American landscape but went functionally extinct towards the end of the Pleistocene. Horses were then re-introduced to North American and many have become wild on western ranges. Their numbers are growing and so is the damage they are causing. We talk with range scientist Eric Thacker about the growing number of wild horses across the west and the need for horse management in order to maintain the fragile ecosystems they graze on.
