| Abstract | Age-old trees play an important ecological and aesthetic role in the landscape gardening industry, but over the past century there has been a decrease in their number and there is a threat of disappearance of individual specimens due to biotic, abiotic and anthropogenic factors. In the current conditions of the full-scale invasion of Russian troops into Ukraine, the problem of preservation, restoration and protection of nature reserves and objects has become particularly urgent, therefore the study of their vital state requires scientific justification. The purpose of the study was to study the phytosanitary condition of age-old trees Quercus robur L. with the status of a botanical monument of nature of local importance of the nature reserve fund of the Kyiv region. The study was conducted during 2022–2025 by the route-expedition method. The extent of tree pathology was determined visually by physiological deviations from the normal state, as well as by the presence of fruit bodies, cancer wounds, hollows, dry tops, etc. In Ukraine, the most numerous group of age-old trees are representatives of the genus Quercus L., of which 26 objects have the status of a botanical monument of nature of local importance in the nature reserve fund of the Kyiv region. According to the results of pathological monitoring, it was established that 11.5% of the studied objects of the reserve background do not have signs of pathologies. The vital state depends on a number of indicators, namely, at the initial stage of degradation of tree stands, contributing factors are found in 23% of objects, they act for a long time, gradually weakening trees, while symptoms do not appear. Stress factors were found in 57.7% of objects, which have an episodic nature of action, but they are real initiating factors. Aggravating factors were found in 65.4% of objects, which weaken trees and lead to their death. According to the results of monitoring of tree stands of the protected background of Kyiv region, the viable state of age-old trees of botanical monuments of nature from the genus Quercus L. was established, while none were classified as category 5, 53.8% of objects were classified as category 3 of the degree of damage, and 15.4% were classified as category 4. Trees classified as category 2 (19.3% of objects) and category 1 (11.5%) had minor damage. Based on the obtained data, an algorithm for monitoring the condition of old-growth stands is proposed. | ||
