从小岛屿(10 平方公里)成功根除哺乳动物入侵外来物种的例子不胜枚举，但从更广泛的地区根除的例子寥寥无几。我们回顾了自1900年以来北欧15次大规模的迁徙(平均面积2627 平方公里)，包括可食用睡鼠、麝鼠、鳕鱼、喜马拉雅豪猪、帕拉斯松鼠和灰松鼠以及美国水貂，每一次都主要基于对静态陷阱的日常检查。目标包括真正根除或完全清除缓冲区，这有别于其他涉及地方控制以限制损害或扩散的方案。12个根除/清除方案(80%)取得了成功。成本随着面积的增加而增加，并得到最好的预测，而单位面积的成本则下降；移走的单个动物的数量对模型没有显著的影响。面积翻倍控制了单位面积成本降低了10%，但没有证据表明成本效益随着时间的推移而增加。与小岛屿相比，较大规模的方案在面积上遵循类似的努力模式。然而，在界定边界和由此带来的围绕成本的不确定性、它们的目标的定义、成功的确认以及管理重新殖民的不同考虑因素时，它们带来了挑战。新技术或增加志愿者的使用可能会降低成本。建议将对新入侵的快速反应作为减少环境、财政和福利成本的最佳做法，而不是大规模控制。©2016皇冠版权所有。《虫害管理科学》由John Wiley&Sons Ltd代表化学工业协会出版。
Numerous examples exist of successful mammalian invasive alien species (IAS) eradications from small islands (<10 km2), but few from more extensive areas. We review 15 large‐scale removals (mean area 2627 km2) from Northern Europe since 1900, including edible dormouse, muskrat, coypu, Himalayan porcupine, Pallas' and grey squirrels and American mink, each primarily based on daily checking of static traps. Objectives included true eradication or complete removal to a buffer zone, as distinct from other programmes that involved local control to limit damage or spread. Twelve eradication/removal programmes (80%) were successful. Cost increased with and was best predicted by area, while the cost per unit area decreased; the number of individual animals removed did not add significantly to the model. Doubling the area controlled reduced cost per unit area by 10%, but there was no evidence that cost effectiveness had increased through time. Compared with small islands, larger‐scale programmes followed similar patterns of effort in relation to area. However, they brought challenges when defining boundaries and consequent uncertainties around costs, the definition of their objectives, confirmation of success and different considerations for managing recolonisation. Novel technologies or increased use of volunteers may reduce costs. Rapid response to new incursions is recommended as best practice rather than large‐scale control to reduce the environmental, financial and welfare costs. © 2016 Crown copyright.
