Question

What is taiga?

Answer 1

The taiga is a type of forest found in the cold and subarctic region.
The subarctic region is an area of the Northern Hemisphere that lies south to the Arctic Circle.
The taiga lies between the tundra to the north and temperate forests to the south.

Complete answer:
The taiga is also referred to as boreal forest.
It is referred to as the world's largest land biome.
In Northern America, it covers most areas of inland Canada, Alaska, and parts of the northern United States.
In Eurasia, it covers most areas of Sweden, Finland and much of Russia from Karelia in the west to the Pacific Ocean.
It also covers the most areas of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and also the areas of northern Kazakhstan, northern Mongolia, and northern Japan.
The Taiga is a recent phenomenon existed for the last 12,000 years since the beginning of the Holocene epoch occurs which covers the land that had been mammoth steppe or under the Scandinavian Ice Sheet in Eurasia and under the Laurentide Ice Sheet in North America during the Late Pleistocene.
In English language the term taiga is often used as boreal forest and in Canada it refers to as the only southern part of biome.
Taiga is used to describe the more barren areas of the northernmost part of the biome approaching the tree line and the tundra biome.
Hoffman in 1958 discusses the origin of this differential use in North America and why it is an inappropriate differentiation of the Russian term.

Note:
Taiga soil tends to be young and poor in nutrients.
It lacks the deeply situated and organically enriched soil present in temperate deciduous forests.
The thinness of the soil is largely due to the cold environment, which stops the development of soil and the ease with which plants can use its nutrients.
