Subarctic Eurasia

Region | Realm

Subarctic Eurasia covers most of the landmass of Russia and the Nordic countries—Iceland, Norway, Sweden, and Finland—and makes up the northern section of the Palearctic realm with four major subrealms as defined in the One Earth Bioregions Framework—Palearctic Tundra, Scandinavian Boreal Forests, Siberian Boreal Forests, and the Sea of Okhotsk & Bering Tundra-Taiga. Palearctic Tundra stretches across the Eurasian continent, surrounding the eastern half of the Arctic Circle. The boreal and coastal forests of Scandinavia extend eastward and meet the Ural Mountains. Siberia is a vast expanse of boreal forests and taiga with some alpine tundra covering much of Russia. The Sea of Okhotsk & Bering Tundra-Taiga subrealm, which includes Sakhalin Island, is particularly important for biodiversity with dense old-growth forests and one of the most biodiverse marine regions in the world, a feeding ground for four whale species, seals, and abundant fish populations.
