The processes of formation of underground and aboveground phytomass in the bog tracts of the natural monument «Boloto Teploe» of the Karachevsky district of the Bryansk region are considered. The aim of the work is to identify the features of accumulation of organic matter and changes in the rate of decomposition processes using the example of reference communities of «Boloto Teploe» for the organization of biomonitoring studies within the framework of the carbon problem. Vegetation in the grassy and woody areas of the bog was inventoried. It was determined that the aboveground and underground phytomass is most significant for tall-grass communities of the Cirsio oleracei-Piceetum abietis association, as well as open bog tracts of the Caricetum cespitosae association, and swampy pine forests of the Vaccinio uliginosi-Pinetum sylvestris community. Significant indicators characterize the phytomass of trunks and leaves in sphagnum spruce and pine forests: biomass reserves vary depending on the size of trees and their number in the sample plot. The highest content of organic matter was recorded for tree communities in bog tracts, for the section of tall-grass spruce forest of the Cirsio oleracei-Piceetum abietis association community. The highest indicators of decomposition of organic residues were found for the conditions of communities of the Climacio-Betuletum pubescentis association, the lowest – for communities of the Vaccinio uliginosi-Pinetum sylvestris association. It was found that woody bogs in the reference areas make a greater contribution to carbon conservation (lower rate of decomposition of residues) compared to grassy bogs; more waterlogged grassy areas of bogs – conserve carbon better than less waterlogged ones, as well as hygrophytic meadow habitats.
