Wildlife managers in Alaska were familiar with numerous situations in which unrestricted hunting of male moose (Alces alces) and caribou (Rangifer tarandus), which also have complex social structures, had resulted in far lower sex ratios and much greater skewing of age structure toward young males than three-quarter curl only hunting had ever caused in Dall's sheep, yet far greater consequences from harvesting males were being claimed for sheep.
The Dry Creek studies focused on Dall's sheep associated with a large mineral lick in the central Alaska Range south of Fairbanks, Alaska, USA (63[degrees]55'N, 145[degrees]25'W).
Most managers and researchers now studying Dall's sheep recognize that harvest figures actually tracked population trends that were regulated by major weather patterns.
