Biogeochemical cycles of Ba, Mn, Cu, Ni and Zn are studied in birch stands situated at various distances from the source of technogenius discharges. It is demonstrated that a 10-year long period of functioning of the hydroelectric power station-1 has not told on the reserves of heavy metals in basic blocks of forest ecosystems and on the flows connecting them. The C balance in birch stands points to their satisfactory ecological condition and capacity of performing their biospheric and environment-forming functions.
