Overview
No other mammal has a closer historical tie to the development of North America than its largest land animal, the bison, also commonly known as the buffalo. Once a prominent fixture on the vast plains of the United States and Canada, bison have survived over-harvesting and near extinction. Their numbers dipped as low as 1,000 head by 1900 but have since recovered and now exceed 500,000 head throughout North America. Today, they can be found in all 50 states, in every Canadian province and in several countries overseas.
Nearly 95 percent of these bison were raised in private herds. In the United States, bison herds account for nearly 270,000 head on 4,000 farms and ranches. Canadian producers add an additional 250,000 head to the North American herd. The balance is part of a Native American herd, lives on public lands (for example, Yellowstone National Park with 4,000 wild, free-ranging bison) or resides in zoos and reserves. (For more information about Native American herds, which number close to 18,000 buffalo, see the InterTribal Bison Cooperative website at http://itbcbison.com/index.php.) April 2007 . . . Bison
