Feral horses and burros in the American West create complex wildlife management challenges. Current management approaches include controversial roundups that raise significant welfare concerns.
Wild horse and burro management is one of the most contested wildlife welfare debates in North America. Helicopter roundups are efficient at numbers but cause significant acute welfare harm — horses run to exhaustion, family bands are broken, and the trauma of capture causes lasting behavioural effects. Long-term holding deprives social animals of the movement and family bonds fundamental to their wellbeing. Fertility control through PZP vaccination offers a welfare-positive alternative that stabilises populations humanely, but requires sustained funding and field deployment. The most welfare-positive management strategy combines fertility control to prevent population growth with expanded adoption and natural attrition, avoiding the need for roundups.
