Feral horse populations in the US, Australia, and elsewhere face welfare challenges from overcrowding, drought, and management interventions. Evidence-based population management protects both horses and ecosystems.
Feral horse welfare involves tensions between individual horse welfare, ecosystem health, and management practicality. Helicopter roundups cause acute welfare harms including stress, injury, and disruption of family bands. Long-term holding of captured horses in inadequate facilities creates chronic welfare problems. Fertility control programs offer a welfare-positive alternative for accessible herds - mares receive contraceptive vaccinations without capture stress or family disruption. Aerial culling causes acute suffering but may prevent the larger-scale suffering of starvation and dehydration during drought. Evidence-based policy that prioritizes fertility control where feasible and minimizes roundup and culling through proactive management offers the best welfare outcomes.
