The Last Herd
In the contiguous United States, wild bison are no longer free-roaming. With low natural mortality rates, the few wild herds that do exist are annually culled or fenced in to control their population. Others, such as those in Yellowstone National Park, are rounded up when they leave park boundaries to prevent the spread of brucellosis, a disease that may be transmitted to cattle. The Henry Mountains bison represent the last genetically pure and brucellosis-free herd that roams over a large area –over 385,000 acres without fences, culling, or roundups. This independent conservation film documents shows how free-roaming bison and private interests can coexist.
