For the last four years WWP's Greenfire Preserve in Custer County, Idaho has been home to a growing band of wild horses. The band is an offshoot of the largest wild horse herd in Idaho that lives 10 miles east of the Preserve in the Spar Canyon area. This summer there are eleven horses including the stallion, seven mares and three foals born earlier this spring. Just this year the horses have had to deal with a mountain lion, wolves and the largest source of anxiety to them – a government helicopter. The horses clearly associate helicopters with great danger primarily because the BLM uses helicopters when they do horse gathers every other year in the area. The band at Greenfire is safe at least as long as they stay around. The band often travels off the property, but spends most of its time east of the river on the Preserve.
