By the Numbers: Bison
The American bison is now the national mammal of the U.S., as a result of a law President Obama signed in May. Millions of these massive animals once roamed across North America. But as pioneers expanded west and the government sponsored hunting programs, the bison population dwindled to barely 1,000 by the 1890s. Due to recent conservation efforts, the American bison population is back to a healthy 500,000 and growing. Bison, also known as buffalo, can now be found in all 50 states, at zoos and in the wild—especially in protected areas like Yellowstone National Park in Wyoming.
