SAN FRANCISCO (CBS SF) - President Obama signed a bill making the North American bison the national mammal of the United States.
Thanks to the National Bison Legacy Act, the once-nearly extinct species joins the American bald eagle as the image of strength and courage for the country.
Early settlers called these large, imposing animals 'buffalo,' but the correct name is, in fact, bison. Unlike buffalo, the bison bears a large shoulder hump and a massive head. Males weigh as much as 2000 pounds and stand 6 feet tall. Despite their bulk, bison can run at speeds up to 45 miles per hour.
Some thirty million bison once roamed the Great Plains but were cruelly hunted almost to extinction by the 19th century.
Thanks to conservation efforts there are now an estimated 20,000 bison roaming free in the U.S. and Canada and even more being raised on private lands.
A coalition of conservationists, ranchers and tribal groups lobbied to craft and pass the legislation making bison the official national symbol.
The Wildlife Conservation Society was among those groups. In an interview with the Washington Post, President Cristián Samper said the bison is an "icon that represents the highest ideals of America: unity, resilience and healthy landscapes and communities."
