MISSION, SOUTH DAKOTA–Rosebud Economic Development Corporation (REDCO), the economic arm of the Rosebud Sioux Tribe, has secured nearly 28,000 acres of native grassland for the creation of a new plains bison herd with the support of the Rosebud's Tribal Land Enterprise. With a capacity to support 1,500 animals, the Wolakota Buffalo Range will become North America's largest Native American owned and managed bison herd. The project is being advanced by a partnership with World Wildlife Fund (WWF)
