List of Bureau of Land Management Herd Management Areas

Herd Management Areas (HMA) are lands under the supervision of the United States Bureau of Land Management (BLM) that are managed for the primary but not exclusive benefit of free-roaming wild horses and burros. While these animals are technically feral equines descended from foundation stock that was originally domesticated, the phrase "wild horse" (and wild burro) has a specific meaning in United States law, giving special legal status to the descendants of equines that were "unmarked and unclaimed" on public lands at the time the Wild and Free-Roaming Horses and Burros Act of 1971 (WFRHBA) was passed.
