"I ask my colleagues to help me support and pass this legislation honoring the bison and designating it as our national mammal," Enzi said. "The bison has and will continue to be a symbol of America, its people and a way of life."

Three states have designated the bison as their state mammal and American bison freely roam national parks, such as Yellowstone and Grand Teton.

"The bison has been integrally linked to the economic and spiritual lives of many Native American tribes over the centuries," Enzi said. "Since our frontier days, the bison has become a symbol of American strength and determination."
