Horses will be pushed into the traps by helicopters and the operation will be open to public observation.
The capture goal is 420. Approximately 30 will be returned to the range, including mares treated with contraceptives, putting the removal goal at 390.
The HMA covers 78,000 acres east of Burns, OR and has an AML of 80.
The aimed-at stocking rate is one wild horse per thousand acres, in line with the target rate across all HMAs.
The horses allowed by plan require 80 × 12 = 960 AUMs per year.
The current population is thought to be around 450, including foals. How does that figure compare to the True AML, which must be determined by calculation? This is where the advocates go off the rails.
The authorizing project can be found in ePlanning.

A keyword search for AUM eventually brings you to Table 3-4, which shows three grazing allotments associated with the HMA.
Current data for the allotments, including active AUMs, permittees, grazing seasons and management status (Improve/Maintain/Custodial) can be found in RAS, using the Allotment Master and Authorization Use reports. The project home page tells you they’re in the Three Rivers Field Office.
The forage allocations in Table 3-4 sum to 8,455 AUMs per year, compared to 960 AUMs per year for the horses. An estimated 8,455 ÷ 12 = 704 wild horses have been displaced from the HMA by privately owned livestock.
Calculation of the True AML is beyond the scope of this post but here’s a first pass:
True AML = Horses allowed by plan + Horses displaced by livestock = 80 + 704 = 784
The HMA is not overpopulated, it is mismanaged.
Captured animals will be taken to the off-range corrals in Hines.
