Tens of thousands of wild horses on US public lands are managed through helicopter roundups, with significant welfare costs that remain controversial.
Helicopter roundups cause documented suffering: horses run for miles in extreme heat, foals are separated from mares, and stress-induced injuries occur regularly. Long-term holding facilities house horses in feedlot-style pens for life. Fertility control programs like PZP vaccine offer a humane population management alternative that is effective, less expensive, and eliminates roundup welfare harms.
