The intensity of anthropogenic impact on forests, according to many researchers, will increase in the next twenty years. In this regard, the area of deciduous plantings in the taiga zone will increase. Knowledge of carbon stocks in green biomass will allow the necessary calculations of the carbon budget of forest ecosystems to be made. Birch in the taiga zone is one of the most significant wood carbon sinks, especially in the initial period of growth. The article used a normative approach to assessing the carbon stock in the leaf fraction of birch plantations. As a result, a number of conclusions were drawn. The use of two series of distributions compiled for birch forests of the forest-steppe and taiga zones showed their insignificant difference in relation to the determination of leaf biomass. The disadvantage of using distribution series when estimating the carbon budget is the inherent linear nature of the dynamics, which does not correspond to the real conditions of the age development of the assimilation apparatus. When determining carbon stocks for the leaf fraction, a high percentage of uncertainty is observed, this is noted by many researchers. To improve the accuracy of estimates of the biological productivity of birch plantations, it is necessary to use local standards and local research data to the maximum.
