Studies on estimated wildlife habitat distribution using GIS and Generalized Linear Modeling commonly use Digital Map 5000 land use data or vegetation data issued by the Geographical Survey Institute and the Ministry of the Environment, respectively. Since the suitability of these data types to such an application has not yet been tested, this study sought to determine which of the two data sets was better suited for the estimation of raccoon habitat. Digital Map 5000 land use data (Model 1) and vegetation data (Model 2) were thus analyzed using a GIS and a generalized linear model. The results were compared with that of the actual information on the presence of raccoons within Osaka Prefecture. The explaining variable of the natural environment was elucidated by a stepwise approach using both models. In addition, differences in land use categories and the accuracy of the two data sets were also found to have influenced to the results obtained. Thus, it is necessary to note the consideration of result to estimate the wildlife habitat distribution using two models.
