FLAGSTAFF, Ariz. — The National Park Service is looking at using sharpshooters, capture and other methods to reduce the number of bison that are roaming the far northern reaches of the Grand Canyon and damaging resources, officials said.
The massive animals can weigh up to 2,000 pounds, and park officials say they are destroying water sources, vegetation, soil and archaeological sites. Hunting is prohibited within park boundaries, but the agency has the authority to kill animals that harm resources, using park staff or volunteer hunters.
