The National Bison Range, established on May 23, 1908, was an early refuge for American Bison, severely endangered at the time. It comprises about about 29 square miles in northwestern Montana, and several hundred bison live there. The US Fish and Wildlife Service operates the Range as a National Wildlife Refuge, and it serves as a center for bison research.
