抄録

Habitat expansion of wild boar (Sus scrafa) cross the waters in Island See is studied based on interview research conducted in all residential islands in Matsuyama City, Ehime Pref., Japan. Wild boar has immigrated around 1999 from the direction of Kashima Island, Hiroshima Pref. in the north. In A group islands where far from original habitat, sporadic damage phase exists for 6-8 years. After damage increase phase of 3-4 years, grate damage phase starts from 2009. In B group islands where near from original habitat, sporadic damage phase relatively short. In other islands far from original habitat and with very small area, wild boar has immigrated but not colonized. Gogo Island is now in sporadic damage phase, but predicted to go into damage increase phase in the near future. It is effective solution of wildlife-human conflict to make opportunity for local people getting information and learning opportunity about wild boar, as well as to monitor wild boar habitat expansion on the edge of original habitat, resulting in effective control of wild boar habitat.
