What is the BLM and what role does it play with wild horses?

The Bureau of Land Management is the federal agency within the Department of the Interior responsible for managing approximately 245 million acres of public land in the western United States, including the herd management areas where wild horses and burros live under federal protection. The BLM's role with wild horses is defined by the Wild Free-Roaming Horses and Burros Act of 1971, which established federal protection for mustangs and burros on public lands and charged the BLM with managing their populations in balance with the land's carrying capacity and the needs of other wildlife and livestock. In practical terms, the BLM periodically gathers wild horses from overpopulated herd management areas using helicopter roundups and holds the gathered animals at short-term and long-term holding facilities while they are offered for adoption or sale to qualified applicants. The adoption program — the primary pathway through which mustangs enter the hands of private trainers and owners — offers young horses at a minimum adoption fee and requires adopters to demonstrate adequate facilities and commit to providing appropriate care for a minimum of one year before the horse's title transfers. The BLM also administers fertility control programs aimed at reducing population growth rates and collaborating with partner organizations like the Mustang Heritage Foundation on gentling and training programs designed to increase mustang adoptability. The agency's management of wild horse populations is a consistently controversial policy area, with ongoing tension between advocates for expanded protections and freedoms for wild herds, ranching interests concerned about competition for grazing resources, and budget constraints that limit the agency's ability to manage large holding populations indefinitely.
