The management of large carnivores in multi-use landscapes is always controversial, and managers need to balance a wide range of competing interests. Hunter harvest is often used to limit population size and distribution but is proving to be both controversial and technically challenging. Eurasian lynx (Lynx lynx) are currently managed as a game species in Norway. We describe an adaptive management approach where quota setting is based on an annual census and chart the population development through the period 1996-2008, as management has become significantly more sophisticated and better informed by the increased availability of scientific data. During this period the population has been through a period of high quotas and population decline caused by fragmented management authority and over optimistic estimates of lynx reproduction, followed by a period of recovery due to quota reductions. The modern management regime is placed in the context of shifting policy during the last 160 years, during which management goals have moved from extermination stimulated by bounties, through a short phase of protection, and now to quota-regulated harvest. Much management authority has also been delegated from central to local levels. We conclude that adaptive management has the potential to keep the population within some bounded limits, although there will inevitably be fluctuation.
多用途景观中的大型食肉动物管理一直存在争议,管理者需要平衡广泛的利益冲突。狩猎收获通常用于限制种群规模和分布,但事实证明,这种做法既具有争议性,又具有技术挑战性。欧亚猞猁(Lynx lynx)目前在挪威被作为狩猎物种进行管理。我们描述了一种适应性管理方法,其中配额设定基于年度普查,并通过 1996 年至 2008 年的时间段来绘制种群发展情况,因为管理变得更加复杂,并且由于科学数据的可用性增加而得到了更好的信息支持。在此期间,由于管理权限碎片化和对猞猁繁殖的过高估计,导致种群数量经历了高配额和下降的阶段,随后由于配额减少而出现了恢复阶段。现代管理制度是在过去 160 年的政策变化背景下提出的,在此期间,管理目标从受赏金刺激的灭绝,经过短暂的保护阶段,现在已经转变为受配额限制的收获。大量管理权限也从中央下放给地方各级。我们的结论是,适应性管理有可能使种群保持在一定的界限内,尽管不可避免地会出现波动。
