Once numbering tens of millions of animals across the North American prairie landscape, bison were hunted to near extinction during the 19th century until fewer than 1,000 remained.  Small herds were saved and protected in reserves such as Yellowstone National Park and at the Bronx Zoo at the turn of the century.  Since then, the population has multiplied to safe numbers as a result of bison restoration and protection efforts on public lands and in private herds.  However, more must be done to keep this species healthy for years to come.
