The incident will begin on or about July 14, according to the BLM news release.
The capture goal is 1,900 and the removal goal is 1,800. Mares returned to the range will be treated with GonaCon.
Helicopters will push the horses into the traps and operations will be open to public observation.
The Complex includes the Maverick-Medicine HMA, Triple B HMA and Antelope Valley HMA west of US Highway 93.
The 821 horses allowed by plan require 9,852 AUMs per year in an area covering over 1.6 million total acres. The Western Watersheds map shows the arrangement.
The current population is thought to be 3,475.
Table 2 in the 2017 EA for resource enforcement actions includes the Cherry Springs WHT in the Complex, with an AML of 68, but it is not mentioned in the announcement.
The HMAs are subject to permitted grazing. Livestock receive an estimated 49,188 AUMs per year, which would support an additional 4,099 wild horses.
Captured animals will be taken to the corrals in Fallon, NV and Sutherland, UT.
Gather stats and daily reports will be posted to this page.
The EA was posted with other project documents.
