Bison Hazed Back into Yellowstone

Billings, MT – Several hundred bison will be hazed back into Yellowstone National Park beginning Wednesday and lasting for several weeks, under a program to prevent the spread of a livestock disease.

Park spokesman Al Nash said the hazing will be done differently than last year, when hazed animals kept pushing back out of the park and into areas where cattle range. That stoked fears among the livestock industry that the bison could transmit brucellosis, a disease that causes cows to abort their young.

Nash said this year's hazing will be carried out more slowly, to make sure bison are not moved too fast to higher elevations where snow still covers forage. He said that should allow the animals to remain in the park once they are moved.
