The allotment, in the Vermillion Cliffs National Monument, offers 15,081 active AUMs on 186,082 public acres, according to the Allotment Master Report.
The forage assigned to horses is zero.
How many wild horses could live there?
Using the principle of forage interchangeability, the True AML would be 15,081 ÷ 12 = 1,257, the number of horses the land could support if it was managed principally for them as specified in the original statute.
The stocking rate would be 1,257 ÷ 186,082 × 1,000 = 6.8 wild horses per thousand public acres.
Why is this important?
The bureaucrats and ranchers claim that public lands in the western U.S. can only support one wild horse per thousand acres (27,000 animals on 27 million acres).
The advocates reinforce the narrative with their darting programs.
If the allotment was an HMA, the AML would be 186 and 1,071 horses would be consigned to off-range holding because of permitted grazing.
BLM allotments in Arizona carry livestock equivalent to 53,662 wild horses on 10,090,546 public acres, or 5.3 wild horses per thousand public acres.
