Zonobiome VIII of the Boreal Conifer Zone (Taiga) of Euro-Siberia
The boreal zone of the northern hemisphere is a circum-polar belt around the Arctic, lying south of the polar forest boundary (see Fig. 8.1). In North America it covers approximately 70° of longitude, in Eurasia slightly more than 160° of longitude (Fig. 8.2). It may be considered as a global unit with a major interruption by the Atlantic Ocean and a smaller one by the Bering Sea.
