On August 11−12, 2017, a hurricane passed from south to north of Poland causing considerable damage to forests, especially in regional directorates of the State Forests in Wrocław, Poznań, Toruń, Szczecinek and Gdańsk. 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...
Climate change, which was particularly marked at the turn of the 20th and 21st centuries, was accompanied by unfavourable weather phenomena. One of whose effects cannot be prevented is hurricane. Much of the most devastating storms (e.g. Kyrill in January 2007, Carmen in November 2010), which crossed over Poland, was associated with low pressure systems. The occurrence of high wind speeds in the cold...
Extreme weather events such as hurricanes, floods or fires become more and more common phenomena in Europe. In August 2017, strong wind accompanied by heavy thunderstorms caused severe damage over the large area in central and western Poland. According to rapid damage assessment prepared by the State Forests authorities a few days after the windthrow, ca 79.7 thousand hectares of forest was damaged...
Obserwowany w Polsce wzrost liczebności zwierzyny grubej, której głównym miejscem bytowania są ekosystemy leśne, dostarczające pokarmu i schronienia powoduje określone konsekw encje przyrodnicze i gospodarcze. W niektórych rejonach kraju liczebność zwierząt kopytnych jest tak duża, że może to zagrażać trwałości lasów. Zdaniem wielu leśników zwierzyna stanowi główną barierę dla osiągania celów hodowlanych...
The aim of the study was to evaluate the area and volume of the windthrows caused by a downburst, which occurred early morning on July 8th , 2015 in the Międzylesie Forest District (south−western Poland). The wind velocity reached 270 km/h and the phenomenon caused damages similar to those observed after the hurricane. The most affected forest ranges included: Różanka, Nowa Wieś, Lesica, Goworów,...
Assessment of the impact of large herbivores on young generation of trees in the protected forests can support decisions about whether to intervene in natural ecosystems (e.g. individual tree protection, animal culling) or not. A study on the condition of forest regeneration, including the assessment of the damage caused by deer, was performed in the Gorczański National Park (GNP; southern Poland)...
