In addition to nearly all of the species of mammals living in Hokkaido, including higuma (brown bear), ezoshika (hokkaido sika deer) and kitakitsune (ezo red fox), there are animals in the Daisetsuzan Mountain Range, such as ezonakiusagi (northern pika), that can only be found in very few areas. Furthermore, more than 6,000 species of insects have been recorded, among them usubakichou (Parnassius eversmanni) and asahihyoumon (Clossiana freija), which only inhabit the Daisetsuzan Mountain Range and nowhere else in Japan. These species are thought to have remained only in cold regions due to global warming after the ice age, and are referred to as “relict species”.
