Abstract
This paper analyzes the patterns of weakening of soft-wooded broadleaved species, provides the frequency of occurrence of the most common external signs of pathologies and their relationship with the general condition of trees. It was found that the most common pathological sign in soft-wooded broadleaved species is drying out of branches (58.2% of the surveyed trees), followed by breakage of skeletal branches (14.9%) and the presence of thick skeletal branches in the crown (14.4% ). Further, as the occurrence of signs decreases, we see trunk inclination of varying degrees (13.9%), where inclination of up to 30° prevails, various pathologies of the trunk shape (12.9%), the most frequent among which was the bifurcation of the trunk, bending of the trunk relative to the normal axis of the tree (7%) and fruiting bodies of wood-destroying fungi (4.1%). Small-leaved linden (Tilia cordata Mill.) was the most stable species in the surveyed plantation, on which the least number of pathological signs was recorded. The revealed features of the external manifestation of pathologies will make it possible to determine the category of the tree state more accurately and increase objectivity and reliability of forest pathological examinations
