The raccoon (Procyon lotor) is an invasive, non-native species in Japan. Throughout the country, it causes significant agricultural damage and negatively affects native biodiversity. Most of the responsibility for raccoon management lies with local government, and there are still many challenges to be overcome. Although raccoon populations have not been eradicated, intensive control campaigns such as focus on the early stages of invasion have controlled raccoons in some regions. To improve the national management of raccoons, we conducted a survey on raccoon management systems in local government departments considered to solve the challenges recognized in many areas. During 2014 and 2015, we surveyed three different municipal departments about raccoon management measures. The semi-structured interview survey covered two topics: (1) the situation leading up to the current management system; (2) the current management system. Our results describe the scope and methods used in raccoon management. The government staff managed raccoons using monitoring, employing a variety of methods, a range of budgets, and various role divisions. The management practices are similar in that they share a sense of taking precautions, collaborating with stakeholders, understanding that adequate methods must be used, and obtaining support from experts. Our case studies reveal the challenges in raccoon management faced by local government officers in regions with active control. The management systems and methods that we surveyed seemed to be effective in solving problems in both developed and undeveloped areas.

浣熊入侵管理系统和主动控制地区面临的挑战


浣熊（Procyon lotor）是日本的一种入侵性非本土物种。在全国范围内，它造成了严重的农业破坏，并对当地生物多样性产生了负面影响。浣熊管理的大部分责任在于当地政府，但仍有许多挑战需要克服。尽管浣熊种群尚未被消灭，但在一些地区，集中控制浣熊的活动（例如重点关注入侵的早期阶段）已经控制住了浣熊。为了改善国家对浣熊的管理，我们对地方政府部门的浣熊管理系统进行了调查，以解决许多领域所认识到的挑战。 2014年和2015年，我们对三个不同的市政府部门进行了浣熊管理措施的调查。半结构化访谈调查涵盖两个主题：（1）现行管理体系的现状； (2)现行管理制度。我们的结果描述了浣熊管理中使用的范围和方法。政府工作人员通过监控、采用各种方法、一系列预算和各种角色分工来管理浣熊。管理实践的相似之处在于，他们都有采取预防措施、与利益相关者合作、理解必须使用适当方法以及获得专家支持的意识。我们的案例研究揭示了积极控制地区地方政府官员在浣熊管理方面面临的挑战。我们调查的管理体系和方法似乎对解决发达地区和欠发达地区的问题都有效。
