Feral Horse Management and Humane Alternatives

Feral horse populations on public lands generate intense management controversy, with welfare advocates pushing for humane fertility control over roundups and long-term holding.

Key Facts

An estimated 86,000 wild horses roam public lands in 10 Western US states
The BLM holds over 60,000 additional horses in long-term holding facilities at a cost of over 1,000 dollars per horse per year
Helicopter roundups cause acute stress, injuries, and deaths including foals who cannot keep up with the herd
Porcine zona pellucida vaccine can prevent pregnancy in mares for 1 to 2 years per dose
Wild horse populations can double every 4 years without management intervention

Welfare Considerations

Roundup operations using helicopters to drive horses at full gallop for miles cause acute stress and physical injury. Foals separated from mares during roundups may die from exhaustion or subsequent starvation. Horses held in long-term facilities experience social disruption and unnatural confinement that causes stereotypic behavior. Immunocontraception programs eliminate these harms by managing populations on the range without capture, but require sustained investment and field delivery infrastructure that government agencies have been slow to fund.
