Description

The objective of this study was to obtain basic information on the Japanese badger (Meles anakuma) inhabiting urban areas. We conducted a survey using a camera-trapping technique to determine the frequency of emergence of wild mammals and their damage to crops at Kagoshima University. Four sensor cameras were mounted at a training area in the Faculty of Education, an experimental farm in the Faculty of Agriculture (fields and a livestock barn), and a botanical garden at the Korimoto campus of Kagoshima University from January to December 2019. The number of photographs of raccoon dog (Nyctereutes procyonoides viverrinus), Japanese badger, feral cats (Felis catus), and Japanese weasel (Musyela itatsi) recorded by the cameras were 147, 113, 41, and 1, respectively. Japanese badger was most frequently photographed at the training area in the Faculty of Education. Regarding monthly variations, the relative abundance index of Japanese badger was higher from May to July and lower from January to March and August than in other months. It was observed in May that Japanese badger took loquats at the training area in the Faculty of Education. These findings indicate that Japanese badger lives in the Korimoto campus all year around and that the animal occasionally causes damages to crops.
