Description

To examine the accuracy of habitat classifications of Japanese butterflies, which were based on the qualitative knowledge of each species, butterfly transect counts were conducted in nine woodland sites (deciduous broadleaf forest and larch plantation) and in nine open land sites (paddy field, arable field, riverbank and dwarf bamboo field) in central Hokkaido. A total of 57 species were recorded. Species composition differed distinctively between woodlands and open lands : 30 species were only recorded in woodlands, whereas four species were only recorded in open lands. According to the abundance of each species in woodlands and in open lands, 38 species were classified into woodland species, nine species were classified into open-land species, and the other 10 species were not classified into either of the habitats. These classifications were mostly consistent with the previous classifications of each species, suggesting the accuracy of the previous classifications. This result suggests that the number of forest-dependent species, which is one of the indicators for sustainable forest management in the Montreal Process, can be measured in butterflies using these classifications.
