Global ecoregion

The Eastern Siberia taiga describes a global ecoregion consisting of Boreal Forest, averaging a large expanse of roughly 1,500,000 sq. miles of Eurasian territory. Therefore, it is no surprise that this taiga covers more than a quarter of Russian lands, thus earning the title as “the largest tract of unbroken forest in the world” by the World Wildlife Fund (courtesy of <http://wwf.panda.org/about_our_earth/ecoregions/eastern_siberian_taiga.cfm>). Specifically, the forest occurs between the Yenisey and Lena Rivers in eastern Russia, and its borders reach the lower edge of the Arctic Circle to the north. (See maps below)
