The continent of Europe comprises a large part of the Palearctic ecozone, with many unique biomes and ecoregions. Biogeographically, Europe is tied closely to Siberia, commonly known as the Euro-Siberian region. The European Environmental Agency (EEA) divides Europe into a total of eleven terrestrial biogeographical regions and seven regional ...
The Scandinavian and Russian taiga is an ecoregion within the taiga and boreal forests biome as defined by the WWF classification (ecoregion PA0608). [1] It is situated in Northern Europe between tundra in the north and temperate mixed forests in the south and occupies about 2,156,900 km 2 (832,800 sq mi) in Norway, Sweden, Finland and the northern part of European Russia, being the largest ...
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [ 2 ] alpine tundra , [ 2 ] and Antarctic tundra.
The shortest growing season is found at the northern taiga–tundra ecotone, where the northern taiga forest no longer can grow and the tundra dominates the landscape when the growing season is down to 50–70 days, [22] [23] and the 24-hr average of the warmest month of the year usually is 10 °C (50 °F) or less.

The term tundra comes through Russian тундра from the Kildin Sami word tūndâr "uplands," "treeless mountain tract." [15] There are three types of tundra: Arctic tundra, [16] alpine tundra, [16] and Antarctic tundra [17] In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow ...
Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

Terrestrial ecoregions of the world. This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial, freshwater, and marine ecoregions.
These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. [1] The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd ...
