Abstract

Compensation programs are used globally to increase tolerance for and help offset economic loss caused by large carnivores. Compensation program funding comes from a variety of sources, and in Wyoming and Idaho, USA and Alberta, Canada this includes revenue from hunting and fishing license sales. We review the patterns of livestock depredation and compensation costs of Alberta's predator-compensation program, and compare Alberta's program to compensation programs in neighboring Canadian and American jurisdictions. Current compensation costs in Alberta are well below historic levels, but have been rapidly increasing in recent years due to an increase in depredation events coupled with increased cattle prices. That increase has caused push back from Alberta's hunting and fishing community that finances the compensation program, although less than 3.6% of Alberta's license levy dollars are used for predator compensation. Hunting effort in Alberta is highest on the same privately owned lands with livestock depredation problems, suggesting that private lands support habitats for hunted ungulate species as well as carnivores. Although compensation programs do not prevent depredation events themselves, compensation programs effectively can support the maintenance of wildlife habitats on private lands.

摘要

补偿计划在全球范围内被用于提高对大型食肉动物的容忍度,并帮助减轻其造成的经济损失。补偿计划的资金来源多种多样,在美国的怀俄明州和爱达荷州以及加拿大的艾伯塔省,这包括狩猎和捕鱼许可证销售的收入。我们回顾了艾伯塔省捕食者补偿计划的牲畜损失和补偿成本模式,并将该省的计划与邻国加拿大和美国司法管辖区的补偿计划进行了比较。目前,艾伯塔省的补偿成本远低于历史水平,但近年来由于受侵害事件的增加以及牛价的上涨,补偿成本迅速上升。这一增长引起了资助该补偿计划的艾伯塔省狩猎和渔业社区的反对,尽管用于捕食者补偿的许可证征费还不到艾伯塔省的 3.6%。艾伯塔省的狩猎努力在有牲畜受侵害问题的私人土地上最高,这表明私人土地为被猎食的有蹄类动物以及食肉动物提供了栖息地。尽管补偿计划本身并不能防止受侵害事件的发生,但补偿计划确实可以有效地支持在私人土地上维持野生动物的栖息地。
