Abstract

The condition of pine stands is one of the most problematic issues of the forest industry in the 21st century, especially against the backdrop of an outbreak of mass proliferation of pine stem pests. This paper presents the state of stands based on the results of the expeditionary forest pathological survey in 4 forestry enterprises of Gomel Polesie in 2017–2020 years. Since 2010, there has been a bark beetle drying out of pine stands in this region. Distribution of pine stands by classes of biological resistance is considered, individual factors and causes of disturbance of plant stability are identified, as well as measures necessary to control pathological processes in pine forests. Root rot, which is an old problem in the region, has had a great impact on the condition of pine forests. The incidence of bark beetle drying increased with an increase in age, the proportion of pine in the composition of forest stands, and the productivity of stands. The origin of the stands did not affect the emergence of bark beetle outbreaks.
