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 is Yellowstone National Park, are rounded up when they leave Park boundaries due to 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.

Despite all this space, Henry Mountains Bison are caught within a complex web of public lands, grass, ranching, and government agencies. The Last Herd, an independent conservation film, documents this delicate balance and provides an example of how free-roaming bison and private interests can co-exist.
