Human-Bear Conflicts Whereas post-release conflict with humans was documented for American (6.1%) and Asiatic black bears (9.7%), the majority of released black bears (94.2%) and all brown bears were not documented to be involved in conflicts (Table 3). The main causes of conflict removals in order of importance for both black bear species were persistent attempts to access unsecured human food resources, livestock damages, and habituated behavior that led to bears approaching humans in search of food; no agonistic behaviors towards humans were reported for any captive-reared bears. Most conflicts, 96.1% for American black and 66.7% for Asiatic black bears, were documented during the first year after release.
