Back Forty Bison is located in the heart of the Ozarks. We are committed to the restoration of the American Bison, our National Mammal. Part of this effort includes a focus on conservation with not only the animal, but the land it inhabits. We are bringing genetic diversity to the bison population in Missouri by bringing in animals from Custer State Park, Antelope Island State Park, Idaho, Kansas, Colorado, and Texas. We are also partnering with conservation groups to bring back Missouri native prairie grasses and grassland birds to all of our pastures.
