The answer can be found by the same method used for the HMA but with more acreage.
The HMA is a subset of the HA, which is a subset of the Reveille Allotment.
The allotment offers 39.1 AUMs per year per thousand public acres.
The HA covers 387,676 public acres.
Therefore, the forage assigned to livestock inside the HA is 39.1 × 387,676 ÷ 1,000 = 15,158 AUMs per year, assuming the resource is evenly distributed across the parcel, enough to support 15,158 ÷ 12 = 1,263 wild horses.
The True AML would be 138 + 1,263 = 1,401, because the HA contains the HMA.
The BLM receives 15,158 × 1.35 = $20,463 per year from ranching activity inside the HA while it spends $5 per head per day, at least, for a total of $2,304,975 per year, to care for the 1,263 wild horses displaced from the HA by permitted grazing.
This is a fine example of how the government caters to special interests, wastes our money and mismanages our public lands.
