The incident will begin on September 17, according to a BLM news release.
Helicopters will force the horses into the traps and operations will be open to public observation, starting on Day 3.
Gather activity on Days 1 and 2 will occur in the Dugway Proving Ground, a military facility not accessible by the public.
The September 7 schedule indicates capture and removal goals of 700 and 400.
The HMA covers 211,592 acres in western Utah, including 204,674 public acres.
The 390 horses allowed by plan require 4,680 AUMs per year.
The stocking rate allowed by plan is 1.9 wild horses per thousand public acres, higher than the target rate across all HMAs of one wild horse per thousand acres.
The pre-gather population is thought to be 920.
The HMA intersects four grazing allotments. Livestock receive over three times more forage than the horses, as explained previously.
The BLM spends 113 times more to care for wild horses displaced from public lands by permitted grazing than it collects in fees from ranching activity inside the HMAs, as discussed yesterday.
Captured animals will be taken to the off-range corrals in Axtell.
Gather stats and daily reports will be posted to this page.
