taiga, 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.
In the taiga biome the Sun is never directly overhead (90°) as it can be in the tropics. The maximum solar angle decreases with increasing latitude. At latitude 50° N in the southern part of the taiga biome the maximum solar angle is 63.5°, and at the Arctic Circle it is only 47°.
taiga , or boreal forest, Open coniferous forest (see conifer) growing on swampy ground that is commonly covered with lichens. It is the characteristic vegetation of the subpolar region of northern Eurasia (principally Russia, including Siberia, and Scandinavia) and northern North America, bounded by the colder tundra to the north and the ...
North America - Boreal Forest, Wildlife, Ecosystems: One of the greatest sweeps of forest in the world, the boreal forest (or taiga) extends in a vast and virtually unbroken sheet of green eastward from the Aleutian Islands through Alaska and northern Canada to the island of Newfoundland.
Taiga - Boreal Forest, Ecology, Species: The taiga is well adapted to development following natural disturbances, which include fire, floods, snow breakage, and insect outbreaks. Characteristic of the taiga is the general lack of late successional species that develop under an intact forest canopy.
The taiga is one of the major biomes of the world. Biomes are regions with similar climates and plants and animals. The main feature of the taiga is its conifer forests. Conifers are trees that form seeds inside cones. The taiga grows across northern Europe, Asia, and North America. Another name for taiga is boreal forest.
The Steppe, belt of grassland that extends 5,000 miles (8,000 km) from Hungary in the west through Ukraine and Central Asia to Manchuria in the east. Mountain ranges interrupt the steppe, but horsemen could cross barriers easily and interact with peoples across the entire steppe.
The global extent of the tundra biome is considerable, accounting for roughly 10 percent of Earth’s surface. The southern limit of Arctic tundra follows the northern edge of the coniferous forest belt.
biome, the largest geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions. It includes various communities and is named for the dominant type of vegetation, such as grassland or coniferous forest.
East of the Urals as far as the Altai Mountains, a narrow belt of birch and aspen woodland separates the taiga from the wooded steppe. Much of the mixed and deciduous forest zone has been cleared for agriculture, particularly in the European section.
