Bison Pet

The end of the ranching era and the onset of the natural regulation era set into motion a chain of events that have led to the bison of Yellowstone Park migrating to lower elevations outside the park in search of winter forage. The presence of wild bison in Montana is perceived as a threat to many cattle ranchers, who fear that the small percentage of bison that carry brucellosis will infect livestock and cause cows to abort their first calves. However, there has never been a documented case of brucellosis being transmitted to cattle from wild bison. The management controversy that began in the early 1980s continues to this day, with advocacy groups arguing that the Yellowstone herd should be protected as a distinct population segment under the Endangered Species Act.
Bison hunting today
Hunting of wild bison is legal in some states and provinces where public herds require culling to maintain a target population. In Alberta, where one of only two continuously wild herds of bison exist in North America at Wood Buffalo National Park, bison are hunted to protect disease-free public (reintroduced) and private herds of bison.
