Abstract

For Hokkaido, various data sources such as literature material and field survey data were integrated to construct a wildlife distribution database for plant, bird, mammal, amphibian, reptile, fish, aquatic and terrestrial insect species. Geographical position information was produced based on 1 km, 5 km, and 10 km mesh codes. The database includes approximately 2,400 thousands data, rendering it the largest scale database for any region in Asia. Using these data, distributions can be analyzed in comparison with the number of threatened species inside and outside of protected areas, and the relation between ecosystem types and the number of species for Hokkaido. Results clarify the possibility that the database can contribute to wide-area biodiversity evaluation and selection of important regions for biodiversity conservation efforts.
