(GARDINER, MT) – The bison roundup in Yellowstone National Park is over. Wildlife managers removed about 600 bison from the park populations which had grown to approximately 46-hundred animals. Last summer the Interagency Bison Management Plan partners determined that the removal of approximately 600 bison from the northern range herd should be conducted through harvest by state and tribal hunters or culled directly through capture and consignment to slaughter or research. Some 163 were hunted outside the park boundary while another 258 were were transferred to tribal partners to slaughter for food supplies, and another 60 were consigned to research. Under an agreement with the secretaries of Agriculture and Interior and the Governor of Montana, a total of 3000 to 3500 is to be maintained in the park as the optimal population.
