Feral Horse Management and Welfare

Feral horse management involves difficult tradeoffs between ecological impact, native species protection, and the welfare of individual horses in herds across the American West and beyond.

Key Facts

Approximately 82,000 free-roaming horses live on federal lands in the American West
The Bureau of Land Management is tasked with managing wild horse populations
Roundups using helicopters cause significant stress and sometimes injuries
Fertility control through PZP vaccination offers a more humane population management option
Wild horses are both ecologically impactful and culturally significant to many Americans

Welfare Considerations

Wild horse roundups often cause acute welfare harms including injuries, foal separations, and extreme stress from helicopter pursuit. Long-term holding facilities house tens of thousands of gathered horses in conditions far below natural living. Contraceptive programs offer a welfare-friendly alternative but require significant ongoing investment. Individual welfare must be weighed against ecosystem-level impacts on native species.
