A wild horse was captured earlier this month in the Ochoco National Forest, near Prineville, OR, because he lost his hear of humans. He had been coming to a campground for a year or more, and was fed, petted and groomed. When the campers departed, he sought food from others and the companionship of their horses, putting both at risk.
The only way to resolve the situation was to remove him to a life of captivity.
See this report, posted today by KMTR-16, the NBC affiliate in Eugene, OR. Note the guidelines for camping and recreating around wild horses.
