The results of studying the state of coniferous plantations and describing forest stands in the region of the southern taiga forests of the taiga zone within the Udmurt Republic (on the territory of Yakshur-Bodyinsky, Igrinsky and Kezsky forestries) are presented. Studies have shown that the cellulose-decomposing activity of the forest litter depends on its moisture content, which is associated with the values of the absolute density of forest stands on the studied sample plots. The analysis of physiological and biochemical parameters of Siberian spruce (Píceaobováta Ledeb.) Was carried out and their comparison was carried out in individuals of good and satisfactory vital state, which did not show statistically significant differences in the content of chlorophylls and carotenoids in needles. It has been shown that, in general, the potential of Siberian spruce specimens associated with the biochemical level of the formation of adaptive reactions is highest in plants in the northern regions of the republic, i.e. in areas with more extreme growing conditions. Materials have been obtained, on the basis of which it is possible to develop a program for monitoring plantings and restoring forest stands.
