The results of long-term (1999–2006) investigations of dynamics of vegetation storages, phytomass growth, dead matter, and net primary productivity (NPP) at oligotrophic and eutrophic peatlands in southern taiga in Western Siberia (Tomsk region) are presented. The storages of phytomass at different ecosystems of oligotrophic bog have similar values. Storages of phytomass at eutrophic peatland are 2 times higher in comparison to oligotrophic bog. The qualitative composition of phytomass depends on vegetation of the studied ecosystems, nutrient availability and hydrothermal conditions. 


Key words: peatlands, biological productivity, net primary production.
