Iowa Tribe of Oklahoma receives relocated bison

GRAND CANYON NATIONAL PARK, Ariz. — 58 bison were transported to the Iowa Tribe of Oklahoma and the Cheyenne River Sioux Tribe of South Dakota, according to a news release from the National Park Service (NPS).

The released said that the bison were transferred from the North Rim of Grand Canyon National Park to the Intertribal Buffalo Council, who transported the animals to the tribes.

Since 2018, 203 bison have been removed from the North Rim with 182 transferred to eight different American Indian tribes through an agreement with the InterTribal Buffalo Council.

In 2014, the NPS started a planning process to manage bison overpopulation at Grand Canyon.

In 2017, a plan was finalized to reduce the herd from 600 to fewer than 200 bison using live capture and transfer, as well as limited lethal removal.

The NPS release said that goal is being met as the 2021-2022 winter population estimate for the herd was approximately 216 animals before calving occurred.
