Hokkaidō Montane Conifer Forests
The Hokkaido montane conifer forests ecoregion covers the mountainous central regions of Hokkaido Island, the northernmost of Japan's main islands. Forests of spruce and fir thrive in the subalpine, cool climate. On the northeastern edge of the island, the conifer forests extend down to the sea under the influence of the cold Oyashio Current coming down from the north, although logging in recent years has put pressure on these stands. Location and description The mountainous region is surrounded by the lower plains and hills of the Hokkaidō deciduous forests ecoregion. Central to the region is the Daisetsuzan Volcanic Group, the location of Daisetsuzan National Park, the largest national park in Japan. The highest mountain on the island, and in the region, is Asahi-dake with an elevation of . Above the conifer line, alpine conditions support thickets of Stone pine ''( Pinus pumila)'' Climate The climate of the ecoregion is '' Humid continental climate, warm summer'' ( ...

Palearctic
The Palearctic or Palaearctic is a biogeographic realm of the Earth, the largest of eight. Confined almost entirely to the Eastern Hemisphere, it stretches across Europe and Asia, north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Mediterranean Basin; North Africa; North Arabia; Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. Both the eastern and westernmost extremes of the Paleartic span into the Western Hemisphere, including Cape Dezhnyov in Chukotka Autonomous Okrug to the east and Iceland to the west. The term was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/ Afrotropic, Indian/ I ...
