Abstract

The article presents the results of a study of cut-down areas in the closet during felling, caring for trees on radial growth and volumetric growth remaining after cutting trees. At the same time, a definition is given of the dynamics of radial growth for trees that were before cutting under the control of competition between remaining trees and trees, and not the gradual influence of trees both before and after cutting. The accuracy of the research is due to high-tech methods for laying trial plots, instrumentally determined radial growth of pine and spruce trees, as well as the use of Quantum GIS capabilities for processing scanned core data and creating digital maps of trial plots, as well as the use of software for further processing of the results Based on the results of a study of radial growth, it was revealed that felling neighboring trees increases the radial growth of spruce trees that are under the canopy or under significant influence of neighboring trees after felling up to 58–60%. In trees that were under influence, after felling, the average radial growth increased by 30–50% compared to the growth of trees without influence. For pine trees that were not subject to significant competition from neighboring trees before felling, the change in growth after cutting neighboring trees was not significant. The increase in volume for trees located next to those cut down increases after felling to 45–48% for trees.
