Taiga is a wild coniferous forest. It consists mainly of spruce, fir, larch, pine (including cedar). This word is Turkic, in the language of some Siberian peoples "taiga" means "mountains covered with forest."
Taiga occupies a huge space in the north of Europe, Asia and North America. In the European part of Russia, the taiga stretches from Karelia to the Urals, then stretches across all of Siberia, including Kamchatka and Sakhalin.
In fact, the largest forest on planet Earth is the taiga, which is several times larger than the Amazon jungle. Taiga accounts for almost 90% of the total forest area, which occupies more than 1/3 of the territory of Russia.
