Mortality reduces overyielding in mixed Scots pine and European beech stands along a precipitation gradient in Europe
(Elsevier Science BV, 2023)
Many studies show that mixed species stands can have higher gross growth, or so-called overyielding, compared with monocultures. However, much less is known about mortality in mixed stands. Knowledge is lacking, for example, ...
The Protection of Ash Trees Against Ash Dieback by Tree Injections
(Elsevier GmbH, 2023)
Ash dieback caused by a non-native pathogenic fungus Hymenoscyphus fraxineus has been decimating populations of European Fraxinus species for over 30 years. Nevertheless, there is still a considerable amount of valuable ...

(North Carolina State University, 2018)
Oven-dry wood density variations are reported for European ash (Fraxinus excelsior L.) and English oak (Quercus robur L.) trees growing in floodplain mixed forests in South Moravia, Czech Republic. Two sites with different ...
FexIKA method parameters affecting black locust heartwood extraction yield
(North Carolina State University, 2018)
The influence of certain adjustable parameters (sample property, temperature, and solvent type) on the advanced fexIKA extraction outputs was determined. Extracts were obtained from black locust (Robinia pseudoacacia L.) ...
Is the quality of the non-native Douglas-fir wood produced in the Czech forests comparable to native softwoods?
(North Carolina State University, 2019)
Important physical and mechanical properties were evaluated for Douglas-fir wood produced in a non-native environment. The specimens were obtained from 15 healthy co-dominant trees growing in three different sites located ...
Evaluation of parameters influencing the withdrawal strength of oak and beech dowels
(North Carolina State University, 2020)
The withdrawal strength of plain dowels with nominal diameter of 8 mm was compared with the spiral dowels manufactured from beech (Fagus sylvatica L.) and oak wood (Quercus robur L.). The test specimens were tested after ...
