| description | Introduction
The increasing temperatures during the growing season in combination with periodic droughts (especially in the last decade) cause the spreading of forest diseases. The research aimed to determine the specificities of pathological processes in the forests in Cherkasy region and the impact of climate changes in 2008–2021 on their health condition.
Material and Methods
Climatic changes were assessed by analyzing temperature and precipitation for the growing seasons of 2008-2021 according to the data of six climate stations in the region and the fluctuation of groundwater levels according to the data of the Institute of Hydrology (Kyiv). Based on the ratio of precipitation and evaporation, moisture coefficients were calculated according to Vysotsky and Ivanov. Changes in the health condition state of pine stands in Cherkasy region for 1992–2018 were analyzed based on forest pathology information from State Specialized Forest Protection Enterprise ‘Kyivlisozakhyst’ and Ukrainian Research Institute of Forestry and Forest Melioration.
Results
From 1994 to 2012, the area of forest stands in which pathological processes were detected gradually and unevenly increased. As of 2021, the area of such stands was about 21,000 hectares. Among them, the largest area is occupied by pine stands (64%) of VII–IX age classes (61%), with a relative density of stocking of 0.7 (62%). The main causes of pine forest deterioration in 2018 were hydrological and climatic factors (74%), while in 2021 there were a variety of diseases. Particularly, the semi-parasitic plant Viscum album ssp. austriacum (Wiesb.) Vollm. on 11.3 thousand ha, root rot on 2.9 thousand ha, needle-eating insects on 2.9 thousand ha were spread, and 0.7 thousand ha were damaged by windstorms. From 2018 to 2021, the area of pine stands with pathological processes has been increased more than five times. The precipitation and temperature during the growing season on the spread of forest pathological processes had direct medium and weak correlations with forest decline area. Changes in the moisture coefficient indicate a tendency to an uneven increase in aridity in the growing seasons of 2008–2021. Groundwater in the right-bank part of Cherkasy region is mainly located at a depth inaccessible to pine root systems.
Conclusions
Pathological processes in the forests in Cherkasy region are widespread in pine forests of VII–IX age classes (61%), with a relative density of stocking of 0.7 (62%). While as of 2018, the main causes of deterioration were hydrological and natural phenomena, as of 2021 they were diseases (root rot), stem pests, and a semi-parasitic plant (Austrian mistletoe). During these years, the moisture regime during the growing season corresponded mainly to the conditions of the dry steppe. The water regime of forest stands in these conditions depends mainly on surface moisture.

Стан лісів Черкаської області, особливо в останні десятиліття минулого століття, став поступово погіршуватися. Площі соснових насаджень Черкащини, в яких виявлено патологічні процеси, з 2018 до 2021 р. збільшилися більш ніж у п’ять разів. Патологічні процеси переважно поширені в деревостанах VII–IX класів віку (61 %) з відносною повнотою 0,7 (62 %). Станом на 2018 р. основними причинами погіршення стану лісів були гідрологічні та стихійні явища, але станом на 2021 р. перше місце посіли хвороби (коренева губка), стовбурові шкідники та рослина напівпаразит – омела австрійська (Viscum album ssp. austriacum (Wiesb.) Vollm.). Кількість опадів і температура за вегетаційні періоди 2008–2021 рр. мають прямі зв’язки з площею поширення лісопатологічних процесів. Водний режим лісових насаджень у цих умовах залежить від поверхневого зволоження. Режим зволоження в періоди вегетації цих років відповідав переважно умовам сухого степу.
