The Hokkaido red-backed vole (Craseomys rex) is a species of rodent in the family Cricetidae.[2] It is found at high altitudes on the island of Hokkaido in Japan and at lower altitudes on some smaller islands nearby. Its natural habitat is temperate forests.
Despite having a total area of occupancy of less than 20,000 square kilometres (7,700 sq mi) and being considered rare, the Hokkaido red-backed vole is listed as being of "least concern" by the International Union for Conservation of Nature. This is because the population seems stable, the vole faces no significant threats and it is present in some protected areas.[1]
