Most serious interactions between the species occur around wolf dens (Peterson et al. 1984). A wolf pack in Alaska was observed keeping a sow brown bear with yearlings at bay and eventually driving them away from the den site. The same pack was also observed driving a large, male brown bear away from the den site (Mech 1981). These bears were attracted by a recent wolf kill and ventured too close to the wolf den. From 1966 to 1974, Haber (1987) recorded 36 wolf-brown bear interactions in wolf pack territories in Denali National Park. Of the 36 interactions, 19 took place at ungulate carcasses in which wolves "won" 9 of the 19. Seventeen of the interactions were not at carcasses. In those cases, wolves harassed the bears or tried to take cubs, and the bears retreated. Steve Fritts (U.S. Fish & Wildlife Service) collected 70 unpublished accounts of bear-wolf interactions (Servheen and Knight 1990).
The results showed no negative trends for wolves or bears due to these interactions. Few instances of direct mortality to either species have been documented. Instances of wolves killing bears and bears killing wolves have been reported, but such events are rare and considered the exception. According to Mech (1981), wolves sometimes kill bears, but likely only young, old, or otherwise weakened bears.
