Male Bison

An adult male bison grazes in a field off of Grand Loop Road on May 15 in Yellowstone National Park. The plan to move bison from Yellowstone National Park to the Fort Peck Indian Reservation by the end of the year is in doubt. Officials meeting in Bozeman on Wednesday said federal agriculture officials are questioning whether bison being held in isolation and tested for brucellosis in Yellowstone will have spent enough time in quarantine.

YELLOWSTONE NATIONAL PARK (AP) — A construction worker in Yellowstone National Park had a run-in with a bison this past week.

Park spokesman Neal Herbert told KULR-TV the man was working east of Fishing Bridge on Thursday morning when a bison knocked him to the ground.

The man was taken to a clinic but Herbert says he did not know the extent of his injuries.

In early June, park officials say a group of tourists was standing on a boardwalk and some came within 15 feet of the bison as it crossed. The animal became agitated and charged them, goring a California woman. She was treated for a hip injury.

Park officials recommend people stay at least 75 feet from bison.
