Some 30 years after wolves (Canis lupus) were implicated in decimating wintering white-tailed deer (Odocoileus virginianus) in a 3000-km2 area of northeastern Minnesota, winter deer still have not recolonized the area. Although habitat in the study area generally remains poor, some regeneration has taken place, and deer have increased adjacent to the area. However, wolf numbers have persisted by preying on moose (Alces alces). We could detect no reason other than wolf predation and deer migration traditions for why wintering deer have not recolonized the area.
