This paper examines the case for, and plausibility of, eradicating American mink Neovison vison from mainland Great Britain and its associated offshore islands. This invasive species causes extensive damage to native fauna throughout Europe, and the UK Government is obliged to eradicate it, if feasible, under the Bern Convention. Current mink control buys time, but is patchy and dependent on substantial funding in perpetuity. If enacted, eradication would be cheaper in the long term and much more effective in preserving native wildlife. The methodology of an eradication campaign is explored, together with risks, challenges, and a tentative timeline and cost. We judge that mink eradication is now logistically feasible, due to technological developments and experience gained from landscape‐scale control. Using live traps fitted with electronic sensors – ‘smart’ traps – as the primary means of catching mink would render the campaign efficient, humane and free of non‐target mortality and negative environmental impacts. The ecological benefits of mink eradication would be profound, including greatly improving prospects for water vole Arvicola amphibius populations. Reinvasion is highly unlikely. The greatest logistical challenge is probably removing mink from Scottish west coast islands. Eradication might take around a decade and be dependent on co‐ordination between many conservation, fishing, farming, and water‐related organisations, together with the consent of landowners. By adding alarms to existing mink traps, land and water managers can pave the way to eradication now. A mink‐free Great Britain would plausibly cost tens of millions of pounds, against which could be set the limitless future costs of mink control. Such a campaign would be by far the world's largest invasive predator eradication project by geographical area and would set a precedent for citizen‐led conservation action globally. Regional trials would be extremely valuable in determining the costs and practicality of a GB‐wide campaign.

无貂GB：从英国及其岛屿根除美国貂皮Neovison vison的观点
本文考察了从大不列颠大陆及其相关近海岛屿根除美国水貂 Neovison vison 的理由和合理性。这种入侵物种对整个欧洲的本地动物群造成了广泛的破坏，如果可行，根据伯尔尼公约，英国政府有义务根除它。当前的貂皮控制可以争取时间，但并不完整，并且永久依赖大量资金。如果颁布，从长远来看，根除会更便宜，并且在保护本地野生动物方面会更有效。探讨了根除运动的方法，以及风险、挑战以及暂定时间表和成本。由于技术发展和从景观尺度控制中获得的经验，我们判断水貂根除现在在逻辑上是可行的。使用装有电子传感器的活捕器（“智能”捕鼠器）作为捕捉水貂的主要手段，将使活动高效、人道，并且不会造成非目标死亡率和负面环境影响。根除水貂的生态效益将是深远的，包括大大改善水田鼠两栖动物种群的前景。再次入侵的可能性很小。最大的后勤挑战可能是从苏格兰西海岸岛屿上清除貂皮。根除可能需要大约十年的时间，取决于许多保护、渔业、农业和与水有关的组织之间的协调，以及土地所有者的同意。通过向现有水貂陷阱添加警报，土地和水资源管理人员现在可以为根除水貂铺平道路。一个没有貂皮的英国可能要花费数千万英镑，可以为水貂控制设定无限的未来成本。这样的运动将是迄今为止按地理区域划分的世界上最大的入侵性捕食者根除项目，并将为全球公民主导的保护行动开创先例。区域试验对于确定 GB 范围内运动的成本和实用性非常有价值。
