Wildlife managers have successfully relocated 100 bison from the North Rim of the Grand Canyon National Park to the Cheyenne River Sioux Tribe in South Dakota, as part of ongoing efforts to manage the bison population. This initiative, facilitated by the Intertribal Buffalo Council, aims to address overpopulation concerns, which affect local water, vegetation, and archaeological sites. Since 2018, 306 bison have been removed, with 282 transferred to eight different American Indian tribes. The effort is part of a broader collaborative plan established by the National Park Service in 2017, involving multiple partners, to ensure sustainable bison management and conservation. The current bison population on the North Rim is approximately 378, indicating a need for continued management. This relocation represents a significant milestone in conserving the park's ecosystem and supporting tribal partnerships.
