The Teton bighorn sheep herd has persisted for 70 years after losing its migration. A recent study found that this herd of 80-100 animals has a unique movement strategy to make the best out of their limited, high-elevation range. This study was led by Alyson Courtemanch, the Jackson wildlife biologist for the Wyoming Game and Fish Department, who was a graduate student at the Cooperative Fish and Wildlife Research Unit at the University of Wyoming while doing this work.
