The Stephens Creek Facility in Yellowstone National Park is currently full of bison. There are two pens at the facility, one for bison that have tested negative for exposure to the disease brucellosis and the other for animals that have tested positive. With no green grass to lure them back in, bison continue to move north out of Yellowstone National Park. Park spokesperson Al Nash explains.

Nash says the facility is now too full to test any more bison for brucellosis, 40% of what was tested showed positive results for exposure to brucellosis.

 On February 15th, Governor Brian Schweitzer signed a 90 day executive order stopping the importation of Yellowstone bison into the state of Montana. This essentially stopped the movement of the bison to processing.
