From a population of 30 to 60 million animals roaming across North America, bison reached a low of about 100 in the wild in the late 1800s. In 1908, President Theodore Roosevelt established the National Bison Range in Montana to maintain a representative herd of bison under natural conditions. Today, approximately 400 bison live in the refuge, enjoying the rolling grasslands. Photo by Justin Schöen (http://ift.tt/18oFfjl).
