Bison Facts

A bull bison can weigh over 1800 pounds and stand 6 foot tall at the shoulder. Bison once roamed the American prairie by the tens of millions and provided a way of life for Native Americans of the Great Plains, but European settlers hunted bison to the brink of extinction (it's estimated that between 300 - 500 animals remained when the federal government passed stricter game laws in 1889).

The American bison (Bison bison) is an inseparable part of American history; no other wild animal has played such a significant role in human affairs. The Native tribes of the American Plains relied on bison for food, shelter, clothing, and as a powerful spiritual symbol.
