Abstract

In pure pine stands growing in the exclusion zone of the Chernobyl nuclear power plant and not subjected to forestry impact for 35 years, in a short period of time (2014–2022) there was a sharp decrease in the stability of trees and their damage by pests and diseases, which led to the formation of pockets desiccation and the death of forest stands. In 2016–2020, 4.6% of the stands of the pine formation died, and forest disease and pest outbreaks covered 6.3% of its area by 2020. In 2022, vital state indices of pure pine forests were 72.4–88.0%, average scores of sanitary condition of stands were 1.40–2.58. The vital state of pine stands in pine forests in the centers of desiccation was estimated by 5.8–75.0% (38.8% on average) and sanitary indices – 1.91–5.44 (3.59 on average). The best by pine stands condition was characterized in isolated forest areas with richer soils. Changes in the growth and productivity indicators of pine stands, the development of disease and pest centers in them and the death of stands were caused by the influence of a complex of external factors against the background of global climate warming. They were based on a decrease in the moisture supply of the territory caused by the imposition of a local drought in 2014–2022 on steadily lowered groundwater levels even before the Chernobyl accident. The development of these processes was facilitated by the wide spread of pure pine forests of artificial origin on former agricultural lands and radioactive contamination of the area, determining the peculiarities of the exclusion zone territory regime and forestry activities in it.
