Abstract
The objective of this study is to assess the values of the soil carbon pool, carbon pools of coniferous and deciduous forests, as well as two main carbon flows - net primary production (NPP) and mortality of coniferous and deciduous forests growing on the lands of the forest fund and defense lands of the Republic of Buryatia. It was determined that the total carbon pool of coniferous forests reaches 752 million tons C. The total carbon pool of deciduous forests reaches 87 million tons C. The total carbon pool of the forest fund territories and defense forest lands is 2962,5 million tons C. The total NPP indicator of coniferous and deciduous forests of the Republic of Buryatia (70.4 million tons C) provides a specific carbon absorption activity equal to, with a population of 985 937 people (2020), 71.4 tons C per person per year. Buryatia is part of the vast Siberian ecological region and plays an important role in climate stabilization,as the Republic's forests are considered one of the key “carbonsinks” of the planet. Data on the amount of carbon in the soil pool and in the carbon pools of coniferous and deciduous forests of Buryatia can be used in calculations to fulfill Russia's international obligation (the Paris Agreement), which considers forests as a tool to mitigate anthropogenic emissions. In addition, boreal forests, including larch, pine and cedar forests of Buryatia, effectively absorb CO, especially in a fairly cool climate, where the decomposition of organic matter is slowed down, which contributes to the accumulation of carbon in soils.
