Its existence as a separate subspecies is disputed. Former distributionWhile the one common name refers to the Badlands region of the Dakotas, it inhabited a larger range that included Montana, Wyoming, Nebraska, South Dakota, and North Dakota.[1] Some sources assert that the subspecies was hunted to extinction in the early 1900s.[2][3] Others claim that the subspecies persisted as long as 1926.[4] Biologists Wehausen and Ramey assert that it was not a unique bighorn sheep subspecies but rather a variation of the widespread Rocky Mountain Bighorn (Ovis canadensi canadensis).[5] Some later studies do not support the existence of the Badlands Bighorn as a distinct subspecies.[6] Rocky Mountain bighorn have replaced the subspecies/variation in its former habitats.[7] See also
