The objective of this study is to provide
improved estimation of the area extent for major mire types within West Siberia
(WS) and determine the spatial variability of NPP and biomass in relation to
macro/micro landscape and site position within the bioclimatic division. Our
approach relies upon scaling up available field survey and literature data to
provide wetland net primary production (NPP) and biomass inventory maps for West Siberia. Both, satellite images and aerial
photography classifications have been used to extrapolate site data into a regional
inventory map (1:2.5M scale). Total NPP of wetlands is estimated as 530.5 TgDM
(teragram/megaton dry matter)yr-1, or 624.4 TgDM/yr when woody parts are
included. Lowest NPP has been assigned to wetlands at the northern part of
Taiga zone (4.5-6.2 tonDM)/ha/yr-1). Wetlands in Tundra, Forested
tundra and southern parts of Taiga zone show considerably higher NPP values.
Minimum of living biomass storage was found in middle and southern taiga
subzones. It is also increased to the north and south within West Siberian
territory.
