A new stage in Yellowstone National Park bison management begins today, as the Interagency Bison Management Plan (IBMP) partner agencies are releasing up to 25 seronegative, monitored and tagged bison to be released onto the land between the northern boundary of Yellowstone National Park and Yankee Jim Canyon, at the northern end of the Gardiner Basin.

A long-awaited shift in Yellowstone National Park bison management is now in place. Bison roaming past Gardiner will be hazed and tested for exposure to brucellosis; those testing negative will be moved to the Gallatin National Forest, while the rest will be moved back to the Park. Critics say the new plan treats bison like cattle.

A plan floated by the Interagency Bison Management Plan to vaccinate Yellowstone National Park bison against brucellosis via air guns and “bio-bullets” is meeting with resistance from the National Park Service and other players in the debate, who say the plan would be largely ineffectual and potentially create “super-strains” of the disease more resistant to traditional vaccines.

High waters in Yellowstone National Park and the Madison River are forcing bison to wander outside the Park's boundaries -- and Montana officials are working to push them back via hazing.

The National Park Service is seeking public input on a proposed plan to treat brucellosis in the Yellowstone National Park bison herd with vaccine delivered via darts and air rifles, designed to minimize the impact on the herd.

A lawsuit brought by the Montana Stockgrowers Association to drastically restrict the movement of bison outside Yellowstone National Park has been dismissed, as a judge ruled the Stockgrowers do not have any rights under a multijurisdictional management plan.

Researchers killed two Yellowstone National Park bison were killed after they fled a science experiment to Yankee Jim Canyon, where bison aren't allowed because of concerns about brucellosis.

Researchers tracing outbreaks of brucellosis in the greater Yellowstone Ecosystem have discovered "hot spots" of the disease far, far removed from Yellowstone bison -- and squarely in the midst of the elk population.

Brucellosis infection among elk in the greater Yellowstone Ecosystem is on the rise, according to a U.S. Geological Survey study recently released in the publication Ecological Applications.
