Laramie, WY – Sixty Yellowstone National Park bison were shipped to slaughter Thursday as part of a state and federal effort to keep brucellosis from being transmitted to cattle from bison that roam outside park boundaries.
The contagious disease can cause bison, cattle and elk to abort. In the past two weeks, 290 bison on Yellowstone's northern edge have been captured and sent to slaughter.
Another 49 bison were hazed Thursday from the Stephens Creek area south toward the Roosevelt Arch at Gardiner.
The National Park Service says Thursday's activities emptied the Stephens Creek capture pens where bison had been held before they were sent to slaughter.
