The Great Plains variety of the sharp-tailed grouse Pediocetes phasianellus jamesi Lincoln was the predominant upland game bird during the exploratory and early settlement period in North Dakota (Coues 1874 and 1878 . Larson 1928, and Williams 1926) . Since then its status has diminished as the prairie grassland gradually was converted to intensively used pastures and cropland. Although the sharptail is still abundant enough in its remaining habitat to provide for liberal annual harvests , further demand on these lands by a growing human population will make it necessary to apply game management measures other than hunting regulations if the sharptail is to be retained as an important game bird in the state.
