In this study, we clarified the process of constructing a capture system and the contents of activities from interview surveys and material surveys. From the results, we clarified the factors that made it possible to build a community-based capture system. The purpose is to examine “how can we build a community-based capture system in an area where the new distribution of wild animals is expanding”. In this study, we conducted a case study in Nakajima Island in Matsuyama City, Ehime Prefecture, where a new catching system was constructed from the situation where there are no wild boar catchers in the area where wild boars have newly expanded. The factors that made it possible to build a new community-based capture system in Nakajima Island are summarized in three points：1）organizational cooperation between the old local government level and local community level, 2）construction of a capture system led by the local community, and 3）multi-layered logistical support through cooperation between prefectural government, city government, and the University. The construction of a capture system at the old local government level made it possible to “create new capturers in the early stages of new distribution expansion” and “continue capture activities in local community level, including small-scale communities”. The residentsʼ association took the initiative in establishing a capture system, which ensured the psychological safety of the capturers and enabled positive and sustainable capture efforts, as well as coordinating interests between existing hunters and local catchers. Furthermore, it is thought that the multi-layered logistical support provided by the cooperation of prefectural government, city government, and the University brought about the scientific knowledge and technology related to capture, which also contributed to the construction of a community-based capture system in the newly habitat expansion area.
