Yellowstone National Park officials have just released information on the number of bison within the park. Sheridan Media's Ron Richter has the details.
Every summer, Yellowstone conducts several aerial surveys of the bison in the park to get an estimate of the number of animals that call Yellowstone home. Park Spokesman Al Nash explains why this annual survey is done.
Nash said that the Interagency Bison Management Plan is a cooperative plan designed to conserve a viable, wild bison population, while minimizing the risk of brucellosis transmission between bison and cattle.
Nash said that the survey showed that there are approximately 3,500 bison in the northern herd and about 1,400 in the central herd this summer. The peak population estimate of 5,000 bison was recorded in the summer of 2005.
