There was a time when there were no wild bison. The last remnant animals were found in the backcountry of Yellowstone. Today, the Yellowstone bison remain as the only pure bison that have no livestock genes.
Even though Yellowstone covers 3,468 square miles, it's not big enough to provide a home for wild bison herds above 3,000 in number. Yellowstone bison have recovered so well that the herds have totaled as many as 4,600 animals. Since wild bison compete with humans for habitat, it is necessary to "manage" this "wildlife."
The video, Conserving Wild Bison discusses the unique problems associated with moving bison, hunting bison, and quarantining bison, some of which have a disease.
