Abstract

The analysis of the dynamics of pathological processes in forest stands in the Kharkiv region for the period of 1992-2012 was carried out based on the database of the forest stands, in which pathological processes were registered, developed in Ukrainian Research Institute of Forestry and Forest Melioration. A gradual uneven increase in the areas of dry pine and oak stands has been noted. As of 2009, the spread of pathological processes had reached a very high level (11,7 % of the area covered with forest). Based on the correlation analysis, an increase in the scale of pathological processes in pine stands was noted with a decrease in solar activity (the Wolf number). A forecast has been made regarding a decrease in the dieback of stands, which is possible only in 2023–2024.
