As well as worldwide the acceleration of extreme climate events, directly related to climate change, is observed in Georgia. The warming process is continuing, which may result in significant changes in forest expansion and forest diversity. Unfortunately these processes are already under way.In the present study we assessed the total biomass stocking in the pinewood cenosis in East Georgia and the carbon stock sequestered in it from the atmosphere.In Eastern Georgia pine-dominated forests make 66.7 thousand hectares, thus amounting to 72.6% of pinewood in Georgia. The total biomass of pinewood cenosis makes 8.74 Tg, where 4.45 Tg of carbon (is sequestered. In the above-ground and underground biomass of the primary floor 3.04 Tg are sequestered, in the shrub layer (underbrush, young plants) – 350.8 Gg; in the herbaceous layer – 10.4 Gg and in the forest floor there are 1.05 Tg of carbon. Average annual growth of pinewood biomass makes up to 123.7 Gg and annual carbon accumulation is 59.6 Gg. In the living biomass of pine-tree forests of East Georgia annually up to 220 Gg of carbon dioxide is sequestered.
