Abstract

Boreal forests are one of the planet’s largest carbon reservoirs. Pine forests of the green moss group of forest types predominate in Eastern Fennoscandia, which is characterized by the predominance of alfehumus soils of light granulometric composition. In the middle taiga communities of Karelia, in protective forests that occupy more than 30% of the territory, overmature stands are quite widespread. A type I intensive level test site was established in the Kivach Nature Reserve, where the distribution of carbon across all ecosystem components was studied in permanent sample plots using methods adopted by the Carbon RITM consortium. The article presents data on carbon reserves in the main pools of dwarf shrub-green moss pine forests. It was established that the studied ecosystems contain on average 168 t C/ha. The phytomass of the tree stand contains 60%—100 t C/ha, the phytomass of the understory and undergrowth—1 t C/ha, coarse woody debris—9 t C/ha, and the living ground cover—3 t C/ha. The second largest carbon pool is the soil pool, with forest litter accumulating an average of 23 t C/ha, and the mineral part—32 t C/ha.
