The fact that wolves prey primarily on the most vulnerable members of the Denali National Park Dall mountain sheep population suggests that wolf predation is not reducing the population dramatically. If it were, then the wolves would have to move on to hunting healthy, reproductive animals to sustain themselves, but they appear to be more selective in their prey choice. Therefore, there is no need to establish a program to cull either the sheep or wolf populations.
