和歌山県における猿害とニホンザルの分布: 目撃例報告からの群れ分布推定の試み

抄録

To grasp distribution of wild Japanese macaques in Wakayama Prefecture, we tried a method of witness report by local people in a village. The study site was Nakatsu Village in Wakayama Prefecture, where actual damages to crops by wild Japanese macaques had been reported. We interviewed local people who engaged in agriculture and asked to report appearance of Japanese macaques during a month by filling a form. Forty seven forms were distributed and 29 of them returned, and 48 cases of witness were obtained. We estimated the distribution of Japanese macaque troops in this village by using those reports and the results of interview. The degree of precision of this witness report is not clear and further intensive studies are necessary to apply this method to broader area.
