U.S. government agencies have abandoned their adherence to the Interagency Bison Management Plan (IBMP) by hazing, or driving, nearly all of the buffalo that are currently in Montana back into Yellowstone National Park, including heavily pregnant females and many newborn calves.
The official purpose of the hazing operations is to “limit the risk of brucellosis transmission from bison to cattle”. However there are no cattle currently present in the West Yellowstone nor will any cattle arrive for well over a month. Brucellosis cross-infection is regarded as a fraud by wildlife experts. There are no recorded cases of wild bison transmitting the disease to livestock, even prior to implementation of the IBMP. The real motive is widely held to be furthering the interests of local landowners and cattle farmers.
The genetically unique Yellowstone bison are America’s only continuously wild herd, numbering fewer than 3,600 animals, compared with a peak population of 30 to 50 million. 1,912 bison have been killed since 2000 under the IBMP. Last winter Federal and State agencies killed or authorized the killing of more than 1,010 bison.
