The bureaucrats and ranchers tell us that public lands in the western U.S. can only support one wild horse per thousand public acres (27,000 animals on 27 million acres).
Therefore, divide the size of the parcel by 1,000, drop the decimals and round the result to the nearest multiple of ten.
The Jordan Meadows Allotment in northern Nevada offers 11,720 active AUMs on 106,495 public acres.
AML = 106,495 ÷ 1,000 = 106.495 → 106 → 110
Wait a minute! The parcel can support 977 wild horses, as noted yesterday.
AMLs are small relative to the available resources so the land can be managed primarily for livestock.
The horses displaced by permitted grazing end up in off-range holding.
Horses consigned to off-range holding = True AML – AML = 977 – 110 = 867
This is why the off-range corrals and long-term pastures are flooded with wild horses.
Later this year there may be more of them off the range than on.
