ИСТИНА

State Forest Registry (SFR) of Russian Federation is a national level compilation of local forest inventory data. SFR contains information about areas and growing stocks of different forest types, separated by dominant tree species, age groups, exploitation and protective characteristics. SFR is main source of initial information for national inventory of greenhouse gases (GHG). Specific sets of conversion factors are used to calculate carbon in biomass and dead wood based on growing stock values. Sets of typical values per area unit are used for estimation of soil and litter carbon pools based on the area information. SFR data, separated by age groups, are used for producing of “carbon growth curves” and the subsequent assessment of carbon increments. Carbon losses with forest felling, forest fires and other destructive disturbances are estimated using the information on clear cuts, burnt and dead forest areas from SFR. The carbon budget is calculated as a balance between increments and losses. Uncertainties estimates are based on errors of conversion factors and typical values. The described approach is used in Russian GHG inventory from 2010 and generates data for UNFCC reporting.
