Which countries have taigas?
Alaska, Canada, Scandinavia, and Siberia have taigas. In Russia, the world’s largest taiga stretches about 5,800 kilometers (3,600 miles), from the Pacific Ocean to the Ural Mountains. This taiga region was completely glaciated, or covered by glacier s, during the last ice age.
What is the taiga?
Vocabulary. 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.
Why is the Taiga in danger?
This exposes the bedrock and permafrost beneath the taiga, which does not support many forms of life. Climate change puts taigas in danger in different ways. Warming climate contributes to a partial thaw ing of the permafrost. Since this water has no place to drain, more area of the taiga is taken over by muskegs.
What are the characteristics of a taiga?
Their dark color and triangle-shaped sides help them catch and absorb as much of the sun’s light as possible. In the taiga, tree growth is thickest beside muskegs and lakes formed by glaciers. Taigas have few native plants besides conifers. The soil of the taiga has few nutrient s.

How much snow does the Taiga get?
The taiga experiences relatively low precipitation throughout the year (generally 200–750 mm (7.9–29.5 in) annually, 1,000 mm (39 in) in some areas), primarily as rain during the summer months, but also as snow or fog. Snow may remain on the ground for as long as nine months in the northernmost extensions of the taiga biome.
Why is the Taiga converting to evergreen?
In Siberia, the taiga is converting from predominantly needle-shedding larch trees to evergreen conifers in response to a warming climate. This is likely to further accelerate warming, as the evergreen trees will absorb more of the sun's rays.
How long has the Taiga existed?
Taiga in its current form is a relatively recent phenomenon, having only existed for the last 12,000 years since the beginning of the Holocene epoch, covering 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 .
Which biome has the lowest average temperature?

What are the dominant trees in the Taiga biome?
Conifers such as this spruce are the dominant trees in the taiga biome. The trees most commonly found in the taiga are conifers. Conifers have a number of adaptations that make them better suited to growing in harsh northern climates than broad-leaved trees: Conifers grow close together and their foliage is dense.
What are the plants that grow in the Taiga?
Common forest understory plants in the taiga include the lingonberry, Canadian dwarf cornel and azalea. Plants such as cotton grasses, bog rosemary and the cloudberry are common in northern bogs .
What type of trees are in Siberia?
Its landscape is dominated by just three main types of tree: spruces, larches and pines. These hardy conifers are better adapted to life in the cold north than broadleaved trees. For much of the year, snow covers the taiga. The above photo shows taiga in Siberia.
What is the largest biome on Earth?
Also known as boreal forest, the taiga lies south of the Arctic tundra and north of the northern temperate forests. Covering around 11.5% of the Earth’s entire land area–that’s roughly 17 million sq. km / 6.6 million sq. miles–the taiga is Earth’s largest land biome. Winters in the taiga are long and cold, and for much of the year ...
What is the name of the biome where trees grow close to each other?
In the southern parts of the taiga biome, the trees grow close enough to each another to create a continuous canopy overhead. This is known as closed canopy forest. In taiga further north, the trees grow more sparsely. There is no continuous canopy and lichen grows on the forest floor between the trees.
What is the most common cause of natural disturbance in the Taiga biome?
The most significant cause of natural disturbance in the taiga is fire, which is usually caused by lightning strikes.
How long does a taiga winter last?
Long winters–which can last as long as nine months, and a wide temperature difference between summer and winter, are both characteristics of the taiga biome. Temperatures generally range from lows of around −54 °C to highs of around 30 °C (−65 to 86 °F).

Overview
Climate and geography
Taiga covers 17 million square kilometres (6.6 million square miles) or 11.5% of the Earth's land area, second only to deserts and xeric shrublands. The largest areas are located in Russia and Canada. In Sweden taiga is associated with the Norrland terrain.
After the permanent ice caps and tundra, taiga is the terrestrial biome with the …
Soils
Taiga soil tends to be young and poor in nutrients, lacking the deep, organically enriched profile present in temperate deciduous forests. The colder climate hinders development of soil, and the ease with which plants can use its nutrients. The relative lack of deciduous trees, which drop huge volumes of leaves annually, and grazing animals, which contribute significant manure, are …
Flora
Since North America and Asia used to be connected by the Bering land bridge, a number of animal and plant species (more animals than plants) were able to colonize both continents and are distributed throughout the taiga biome (see Circumboreal Region). Others differ regionally, typically with each genus having several distinct species, each occupying different regions of the taiga. Taigas …
Fauna
The boreal forest, or taiga, supports a relatively small variety of animals due to the harshness of the climate. Canada's boreal forest includes 85 species of mammals, 130 species of fish, and an estimated 32,000 species of insects. Insects play a critical role as pollinators, decomposers, and as a part of the food web. Many nesting birds rely on them for food in the summer months. The col…
Fire
Fire has been one of the most important factors shaping the composition and development of boreal forest stands; it is the dominant stand-renewing disturbance through much of the Canadian boreal forest. The fire history that characterizes an ecosystem is its fire regime, which has 3 elements: (1) fire type and intensity (e.g., crown fires, severe surface fires, and light surface fires), (2…
