**The Four Mile Wild Horse Gather concluded as of September 15, 2021**

The Bureau of Land Management Boise District, Four Rivers Field Office, on September 14, 2021, began the capture of approximately 189 wild horses and removed approximately 173 excess wild horses within and outside of the boundaries of the Four Mile HMA. The population before that gather was approximately 210 wild horses. The Appropriate Management Level is 37-60 wild horses. The helicopter gather lasted 2 days.

Purpose of Gather:

The purpose of the gather was to prevent undue or unnecessary degradation of the public lands associated with excess wild horses, and to restore a thriving natural ecological balance and multiple-use relationship on public lands, consistent with the provisions of Section 1333(b) of the 1971 Wild Free-Roaming Horses and Burros Act and the Cascade Resource Management Plan. The primary issue in this HMA was the availability of water and forage.

Forage is allocated for 37 wild horses or 444 Animal Unit Months (AUMs) in the Four Mile Herd Management Area (HMA). Monitoring data indicate that when the total horse population begins to reach the upper limit of 60 animals (720 AUMs), resource conditions begin to decline, especially in areas near water sources. 

Details of Gather:

This helicopter gather began on September 14, 2021 and lasted 2 days. The population of the Four Mile HMA before the gather was approximately 210 wild horses. The Appropriate Management Level is 37-60 wild horses. Approximately 189 wild horses were expected to be gathered, and an estimated 173 horses will be removed from the range. Of the remaining horses, eight mares treated with fertility control and eight studs will be released back to the HMA. Horses removed from the HMA will be transported to the Boise Off-Range Corral Facility, where they will be prepared for BLM adoption and sales programs.

The Four Mile HMA consists of 18,800 total acres (16,761 BLM acres, 925 acres of State of Idaho (IDL) lands, and 1,114 acres of private land). It is located approximately 20 miles north of Emmett, ID, within the Willow Ridge grazing allotment, and is bordered on the east by Big Willow Creek and on the west by Four Mile Creek. 

Wild horses in the Four Mile HMA are descendants of domestic horses that were released into the wild in the 1800s and early 1900s. For many years, local residents captured the wild horses and bred them with a variety of private stock. Wild horses in the HMA represent a variety of colors and coat patterns, including grey, bay, sorrel, black, appaloosa, and pinto. Adult horses in the HMA weigh an average of 1,000 pounds and stand between 14 and 15.5 hands, with some individuals standing 16 hands and weighing over 1,200 pounds. Animals in the herd are healthy, with high reproductive rates. 

The last wild horse helicopter gather on the Four Mile HMA occurred in 2009, when 123 horses were captured, 112 horses were removed, and 11 horses were released back into the HMA.
