Detailed explanation-1: -taiga, also called boreal forest, biome (major life zone) of vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in northern circumpolar forested regions characterized by long winters and moderate to high annual precipitation.

Detailed explanation-2: -The most extensive conifer stands are found in the higher latitudes in the Northern Hemisphere through the boreal forests of North America, Asia, and Europe; however, they are also common in tropical areas.

Detailed explanation-3: -The taiga is the driest and coldest of the three and is sometimes called the boreal forest or the coniferous forest. It is the largest of all the land biomes. The taiga has several characteristics that distinguish it from the other forest biomes. First, it is covered with evergreen, or coniferous, trees.

Detailed explanation-4: -The taiga is a forest of the cold, subarctic region. The subarctic is an area of the Northern Hemisphere that lies just south of the Arctic Circle. The taiga lies between the tundra to the north and temperate forests to the south. Alaska, Canada, Scandinavia, and Siberia have taigas.
