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 warmer temperate zone to the south. Spruces and pines are the dominant trees. Soil organisms are protozoans, nematodes, and rotifers; larger invertebrates (e.g., insects) that decompose plant litter are lacking, so humus accumulates very slowly. The taiga is rich in fur-bearing animals (e.g., sable, fox, and ermine) and is home to elks, bears, and wolves. Siberian taiga alone accounts for 19% of the world's forested area and possibly 25% of total forest volume. Despite the remoteness of the taiga, it is a major source of lumber for construction, and huge expanses have been clear-cut.
