The effectiveness of the reformation of soft-leaved plantations into coniferous-deciduous in the territory of the Republic of Tatarstan

The long-term experimental and production work on the transformation of soft-leaved plantations into coniferous on the territory of the Republic of Tatarstan is analyzed and summarized. Surveys were carried out in 2023. In areas of sprus-fir-deciduous t plantations created in 1962-1990 by 2-4-receiving cuttings of reformation of soft-leaved plantations with the growth of spruce and fir, 8 plots with a total area of 24.6 hectares were surveyed, on which 16 test areas were laid. In the derived soft-leaved plantations, 3 control plots with a total area of 8.2 hectares were allocated without re-forming logging and 6 trial areas were laid. The analysis of the state of spruce-fir plantations formed by the felling of soft-leaved plantations into coniferous-deciduous ones convincingly proves their forestry, ecological and economic efficiency, as well as the expediency of further application in the appropriate forest growing conditions of Tatarstan.
