Over the past two decades, domestic horses have been abandoned on abandoned mine sites in eastern Kentucky, forming unmanaged herds. Unchecked breeding has resulted in overpopulation, and according to the Kentucky Humane Society, this is putting horses at risk of starvation, increasing roadway hazards, and causing environmental damage through overgrazing and erosion. Most of these horses were born in the mountains and have never been handled, making traditional management strategies more difficult. KHS Equine Director Lori Redmon tells us about a fertility control program now getting underway.
