Wild Horse and Burro Management in the American West

Wild horses and burros on US public lands are managed by the Bureau of Land Management through roundups and holding programs. Welfare concerns are significant and reform efforts are ongoing.

Key Facts

The BLM manages approximately 86,000 wild horses and burros on western rangelands, with an estimated on-range population of 82,000 as of 2023.
Helicopter roundups cause significant acute stress — horses are chased for miles before capture; injuries and deaths occur regularly.
More than 60,000 animals are held in long-term holding facilities — often crowded feedlots — at a cost of $50,000+ per animal over their lifetime.
Fertility control (PZP vaccine) offers a humane alternative to roundups for population management; uptake has been slow but is growing.
Wild horses and burros are protected under the 1971 Wild Free-Roaming Horses and Burros Act but management remains deeply controversial.

Welfare Considerations

The management of wild horses and burros in the American West illustrates how political and economic forces can generate welfare outcomes that are costly for both animals and taxpayers. Helicopter roundups are acutely stressful; long-term holding subjects social animals to crowded, barren conditions for years or decades. Fertility control is a more humane and ultimately more cost-effective approach, but requires long-term commitment and field work. The welfare case for shifting the management model toward non-lethal population stabilization is strong and supported by growing evidence.

What You Can Do

Support organizations advocating for expanded use of PZP fertility control on wild horse ranges.
Oppose policies that permit slaughter of excess wild horses and burros.
Adopt or sponsor a wild horse or burro through BLM adoption programs.
Advocate for increased funding for on-range management approaches over holding facilities.
