Distribution
editThe Hokkaido red-backed vole occurs in the southwestern part of Hokkaido in the Hidaka Mountains, Daisetsuzan Volcanic Group, Teshio Mountains, and Kitami Mountains, and Shiribeshi Province, Oshima Subprefecture and Hiyama Subprefecture. It is also present at lower altitudes on the islands of Rishiri and Rebun, as well as Shikotan in the Kuril Islands and Shibotsu in the Habomai Islands. It is found in forests and is an adaptable species.[1] Population genetic structuring is rather strong on Hokkaido, with different regions being characterised by different genetic lineages.[3]
Status
editDespite 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]
