How Many Wild Horses Can the Fox-Lake Range HMA Support?

The 204 horses allowed by plan require 2,448 AUMs per year.

Table 7 in the Final EA for resource enforcement actions in the Smoke Creek Complex identifies two allotments that intersect the HMA.  Pole Canyon is 100% inside, along with 90.3% of Rodeo Creek.  Click on image to open in new tab.

Fox-Lake Range Allotments 12-09-21

The Allotment Master report shows 540 AUMs per year available to livestock in Pole Canyon and 5,542 AUMs per year at Rodeo Creek.

The total estimated forage inside the HMA, assuming the resource is evenly distributed across the allotments, is 2,448 + 540 + .903 × 5,542 = 7,992 AUMs per year.  The actual amount may be a little higher due to an allowance for wildlife.

The number of wild horses the HMA can support, if it was managed principally for those animals as specified in the original statute, is 7,992 ÷ 12 = 666.  This is the True AML.

The number of wild horses displaced from the HMA by privately owned livestock is (540 + .903 × 5,542) ÷ 12 = 462, about 0.9% of those in off-range holding.

True AML = AML + Horses displaced

The advocates will tell you that the question is almost impossible to answer, but it’s not that difficult if you’re willing to dig through ePlanning and RAS for the relevant data.
