Laramie, WY – More than a hundred bison were captured for slaughter Thursday as they left Yellowstone National Park, bringing the total captured this winter to 661.
The Montana livestock industry and government agencies say the bison could transmit a disease that causes some pregnant livestock to abort their calves.
With heavy snowfall in Yellowstone this winter, bison have been moving to lower elevations outside the park in search of food.
Almost all the animals captured this winter have come from the park's northern herd, including the 114 rounded up Thursday near the town of Gardiner.
That herd, one of two in Yellowstone, had roughly 1,500 animals at the start of winter.
There have been no recorded bison-to-cattle transmissions of brucellosis, the disease that spurred the capture program.
