36-511: Is occupied by Betula ermanii . The zone above 500 m is occupied by Picea jezoensis and Abies sachalinensis along with broad-leafed trees. The lowest zone below 500 m is occupied by broad-leafed trees, including Quercus mongolica , Acer pictum subsp. mono and Cercidiphyllum japonicum . Resident bird species include hazel grouse , black woodpecker , great spotted woodpecker , white-backed woodpecker , goldcrest , Eurasian treecreeper , and spotted nutcracker . Summer visitors to

45-772: The Hidaka Metamorphic belt. This is characterized by low to medium pressure metamorphic rocks with sedimentary rocks from the Cretaceous- Lower Miocene . Plutonic rocks intrude into these structures. For the most part, the Hidaka mountains are composed of schists , migmatites , gneisses , and granites . The Hidaka mountains are the only mountains in Hokkaido to show evidence of glaciation . This occurs above 1,400 metres (4,600 ft), where one can find moraines and more than 20 cirques from Mount Kitatottabetsu in

This is characterized by sedimentary rocks from the Cretaceous and Jurassic-Lower Cretaceous periods. The eastern end of the range is tertiary metamorphic rock as part of

72-533: The north to Mount Toyoni in the south. Mount Apoi is known for endemic alpine plant life, such as Callianthemum miyabeanum ( ヒダカソウ , Hidaka-sō ) . The Hidaka Mountains are also one of the last refuges of the Hokkaido bear ( Ursus arctos yesoensis ) and Hokkaido deer ( Cervus nippon yesoensis ). The mountains can be divided into four zones. The topmost zone (1,400–1,600 m) is colonized by Siberian dwarf pine and other alpine flora . From 1,200 to 1,300 m

81-544: The range lies in the Hidaka-sanmyaku Erimo Quasi-National Park (日高山脈襟裳国定公園, Hidaka-sanmyaku Erimo Kokutei-kōen ). Since the mountain range lies so far north, the alpine climate zone lies at a lower altitude. The Hidaka Mountains formed in the late Quaternary as part of the outer arc of the western end of the Kuril Island Arc . They were formed by the uplift resulting from the collision with
