By the end of 2018, the volume of wind−broken and wind−fallen trees and deadwood approximated to 9 million m³. In 9 forest districts the harvested volume exceeded 440 thousand m³, including...
A dynamic process of mortality of Norway spruce stands in south−west Poland, mainly in the Sudety Mts. was observed in 2015.

The aim of the paper was to verify the hypothesis that the application of the stand damage risk model allows...
In June 2016, a hurricane damaged the forests of the Regional Directorate of the State Forests in Białystok (eastern Poland), resulting in the removal of approximately 1.9 million cubic meters of wind−fallen and wind−broken trees and deadwood by the end of 2018.

The occurrence of high wind speeds in the cold...
