Abstract
We showed the effect of habitat isolation on rescue data of raccoon dogs, Nyctereutes procyonoides viverinus, in suburban area. We analyzed the factors associated with the rescue data from the relationship between the distribution of rescue points and the landscape patterns using GIS. We found that the populations in areas scoring the high isolation index (0.4 to 0.8), 105 m2 to 106m2 areas of forest landscape, and the low proportion (<0.4) of grassland landscape were suffered from high numbers of rescue data. The area proportion of the isolation index in forest landscapes which did not exceeded 0.4 were 0.10; the area proportion of the averaged area of forest landscape that exceeded 106 m2 were 0.51 and the area proportion of grassland landscape around the forest landscape exceeded 0.4 were 0.34 in the Kanagawa Prefecture.
