Human persecution and habitat loss have endangered large carnivore populations worldwide, but some are recovering, exacerbating old conflicts. Carnivores can injure and kill people; the most dramatic form of wildlife-human conflict. In Scandinavia, the brown bear (Ursus arctos) population increased from ~500 bears in 1977 to ~3300 in 2008, with an increase in injuries, fatalities, and public fear of bear attacks. We reviewed media coverage and interviewed victims to explore how bear population trends, hunter education, and other factors may have influenced the number of injuries and fatalities in Scandinavia from 1977 to 2016. We found 42 incidents with 42 injuries and 2 fatalities; 42 were adult men, one was an adult woman conducting forestry work, and one was a boy skiing off-piste. Thirty-three adult men were hunting bears, moose, or small game, often with a hunting dog, and 26 had shot at the bear at 8±11 m before injury. Eleven nonhunters were conducting forestry work, inspecting a hunting area, picking berries, tending livestock, hiking, harassing a denned bear, and one person was killed outside his house at night. Eight of the 11 incidents of nonhunters involved female bears with cubs; three of these family groups were in dens and two were on carcasses. The annual number of hunters injured/killed was mostly influenced by the increase in the bear population size. The pattern was similar regarding injuries/fatalities to other outdoor users, but the relation with the bear population size was weaker than for hunters, and the null model was equally supported. Bear physiology at denning may make encounters with bears more risky in the fall, when bears show prehibernation behavior. Awareness and education efforts, especially among hunters, seem important to ensure human safety. Recreationists and forestry workers should avoid dense vegetation or make noise to warn bears of their presence.
人类的迫害和栖息地丧失使全球大型食肉动物的数量受到威胁,但有些物种正在恢复,这加剧了旧有的冲突。食肉动物会伤害和杀死人类;这是最具戏剧性的野生动物与人类冲突形式。在斯堪的纳维亚,棕熊(Ursus arctos)的数量从 1977 年的约 500 只增加到 2008 年的约 3300 只,受伤、死亡和公众对熊袭击的恐惧也随之增加。我们回顾了媒体报道并采访了受害者,以探讨棕熊种群趋势、猎人教育和其他因素如何影响 1977 年至 2016 年斯堪的纳维亚地区的受伤和死亡人数。我们发现了 42 起事件,有 42 人受伤,2 人死亡;42 人为成年男性,1 人为从事林业工作的成年女性,1 人为滑雪的男孩。33 名成年男性在猎熊、驼鹿或小型猎物,通常有一只猎犬,26 人在受伤前在 8±11 米处向熊开枪。11 名非猎人在从事林业工作、检查狩猎区、采摘浆果、饲养牲畜、徒步旅行、骚扰一个有幼崽的巢穴,还有一人在夜间被杀死在自家屋外。11 起非猎人事件中有 8 起涉及带着幼崽的母熊;其中三个家庭群体在巢穴中,两个在尸体上。受伤/死亡的猎人人数主要受熊种群数量增加的影响。其他户外活动者的受伤/死亡模式也类似,但与熊种群数量的关系较弱,零模型同样得到支持。熊在巢穴中的生理状态可能使它们在秋季表现出冬眠前行为时更容易与熊发生冲突。提高认识和教育工作,特别是针对猎人,对于确保人类安全似乎很重要。娱乐者和林业工人应避免茂密的植被或发出噪音,以警告熊它们的存在。
