Unusual appearance of Japanese black bears (Ursus thibetanus) has seemed to increase after
the latter half of the 1990s. Since black bears are endangered in western Japan, the viewpoint of
protection should be considered along with the avoidance of fatal and injurious human-bear
encounters. Prediction about moving-site-selectivit yof irregularly wondering black bears may
help responsible administrates and local inhabitants when they select better countermeasures. In
this study, we examined predictability of the moving-site-selection of the animals using 73
encounters between humans and an irregularly wondering bear recorded in areas of
southeastern Hyogo including Rokkou Mountain, northern Osaka and southwestern Kyoto, in the
period of June 29 to October 6, 2000. The predictabili twyas estimated from a model obtained by
logistic correlation, with vegetation classifie dinto 27 types and human density as independent
variables and the bear used or not used as objective variables. Present individual recorded
chose three types of forest vegetation as moving-sites: Japanese cedar - Japanese cyress
afforestation, Quercus serrata dominant forest and Pinus densiflora dominant forest. The bear
may choose these forests not as habitat but as escape cover. Selected moving-sites also
overlapped small-scale residential sections adjoining the forests. On the other hand, the bear
avoided places characterized by high human density.
