Abstract

In Osaka Prefecture, naturalized raccoon has been seen in the latter half of the 1990's. The increase of raccoon has become a big problem because it damaged farm crops. In this research, the habitat distribution of raccoon in Osaka Prefecture was estimated using the GIS and the logistic regression analysis. Information on the presence of raccoons from January 1998 to July 2004 was collected and used in the analysis. The result indicated that the proportion of urbanized area, agricultural land, open water and woodland could significantly influence the distribution of the species. Based on the logistic regression models the distribution of raccoons within Osaka Prefecture was estimated using GIS. Therefore, the regions with the possibility of the raccoon lives in Osaka Prefecture could be investigated.
