Climate change manifest itself as increased natural disturbances. These effects can be reduced by planting adapted forest reproductive material. Such plantation ensure the source of raw material for bioeconomy, but are affected by dendrophagous insects, including pine weevil (Hylobius abietis). This species is estimated to cause 120 million EUR financial losses annually. Untreated coniferous seedlings have very high mortality, therefore pesticides are applied in nurseries, before delivering the plants to forest. U...

Frequency of storms and wind speeds in gusts had been increasing in Northern Europe in last decades, causing more damages to forest stands. Establishment of mixed stands had been suggested as one of the methods to reduce wind damages in future, however, empirical information on actual efficiency of this approach is still limited, especially in relation to summer storms. Therefore aim of our study was to assess summer storm damages in mixed birch spruce stands. Area influenced by the storm of June 2021 in Northern ...

Birch (Betula spp.) has a notable financial value and is less affected by most significant biotic factors than common coniferous tree species, however, still prone to wind and freezing rain damages. Main storms affect Northern Europe during winter (when trees are at leaf-less state), however it might change as the climate is warming and length of the vegetation period is increasing. Therefore information on wind damages in birch stands during this period is important. Aim of our study was to assess the damages cau...

European aspen (Populus tremula L.) is fast growing, almost exclusively naturally regenerated trees species, significant for biodiversity, but also with notable financial value. It is prone to browsing damages and rot. Limited information on traits important to wind resistance had been collected so far and used to adapt models predicting wind damages in stands of these tree species. Main storms affect Northern Europe during winter time (when trees are at leaf-less state), however, summer storms are becoming freque...
