Citing overpopulation, USNPS to transfer more than 400 bison off Grand Canyon NP's North Rim

The plan announced this week calls for the herd reduction to be accomplished over a three-to-five year stretch. The reduction will be made by "utilizing skilled volunteers and non-lethal capture and transfer to cooperating agencies and tribes," the Park Service announced.
