Justification of Ecoregion Delineation This is the vast coniferous forest ecosystem that extends from the Urals to the Yenisei River. In general, the ecoregion boundaries correspond to Kurnaev’s (1990) taiga in the Western Siberian province from the Ural Mountains to the Yenisei River. However, Kurnaev’s taiga east of the Yenisei River was attached to the East Siberian taiga ecoregion since the Yenisei is considered a significant biogeographic boundary in most sources. The Ural Mountains boundary was taken from Europe.
