Over 30 bison are being re-located from the North Rim of the Grand Canyon to the Quapaw Tribe in Oklahoma. National Park officials say after identification and selection, 31 bison were corralled and then loaded into trailers to the move to the heartland. Officials say the transfer was handled quietly and without harm to the animals. The goal of the pilot program was to capture and relocate up to 100 bison. There’s around 600 bison on the North Rim and park officials want to reduce the herd to under 200 over the next three to five years to protect park resources from the impacts of the bison population.
