Tundra Biome Map . Tundra Climate. The tundra biome is an ecosystem situated near the North Pole in the Arctic Circle. It is by far the coldest of all biomes. The winters are extremely cold with temperatures typically below -34° C. The summers last only about two months and the temperatures are still very cold ranging from 3° to 12° C. This biome still sustains life although it encounters these extreme temperatures. Some animals, insects, and even plants thrive there. Yearly precipitation, including melting snow, is 150 to 250 mm. The arctic tundra biome ranges from 300 to 11,079 feet in elevation.. Key Features of the Boreal Forest Biome. This biome has short summers and long cold winters. It has moderate precipitation. A few species of evergreen or coniferous trees like pine, spruce, fir, cedar and larch dominate the plant cover. Coniferous trees are adapted to survive the cold climate and acidic, poorly drained soils. The Taiga terrain (Russian word) alternates between bogs and coniferous forests..
