Taiga - Wikipedia
Taiga or tayga , also known as boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest is the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous … See more
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. … See more
Since North America and Eurasia were originally connected by the Bering land bridge, a number of animal and plant species, more animals than plants, were able to colonize both land masses, and are globally-distributed throughout the taiga biome (see See more
