In order to install effective animal passages, it is necessary to clarify the structure and the position of passages crossing roads. However, there are only few road-crossing facilities for wild animals as measures to prevent habitat fragmentation in Japan. Automatic cameras were set beside road-crossing facilities which are waterways and passages for people to investigate how well animals are using those facilities. Photographs were taken of the medium-sized mammals such as hares, raccoon dogs, foxes, martens, Siberian minks badgers, and masked palm civets. Especially rabbits, raccoon dogs and foxes often passed through. These three species account for approximately 80 percent of those animals that pass through in this area. In this analysis, it shows that each species prefers different types of facilities. According to this investigation, the authors suggest the structure and/or position of effective facilities for each species.
