Taxation of forest stands on 29 plots conducted of the Lyalsky test site in the Central-Eastern Forest Taxation District of the European part of Russia was carried out during August 2023

The taxation characteristics of a forest stand include: forest type, tree species, diameter, height, age, state, and degree of decomposition for fallen trees and stumps. Forest taxation was carried out according to the methodology [Fieldwork methodology for forest inventory on a test site as part of the implementation of the important state-level innovative project 'Carbon in Ecosystems: Monitoring'.

The research was carried out by employees of the Institute of Biology of Komi Science Centre of the Ural Branch of the Russian Academy of Sciences as part of the most important innovative project of national importance 'Development of a system for ground-based and remote monitoring of carbon pools and greenhouse gas fluxes in the territory of the Russian Federation, ensuring the creation of recording data systems on the fluxes of climate-active substances and the carbon budget in forests and other terrestrial ecological systems' (Registration number: 123030300031-6).
