Yellowstone Releases Summer 2014 Bison Population Estimate
Yellowstone National Park has completed its annual summer bison population monitoring.
The population is estimated to be 4,900 bison. The estimate is based on a series of aerial surveys. This level is similar to the 2013 summer estimate. The peak population estimate of 5,000 bison was recorded in the summer of 2005.
According to a news release from the park there are approximately 3,500 bison in the Northern herd and 1,400 in the Central herd this summer. There were about 740 calves-of-the-year observed in a June aerial survey.
This population estimate is used to inform adaptive management strategies under the Interagency Bison Management Plan, a cooperative plan designed to conserve a viable, wild bison population while minimizing the risk of brucellosis transmission between bison and cattle.
