Context: The relationship between silvicultural management and the quality of timber produced is not entirely elucidated. Aims: The effects of thinning on structural grade-determining properties of wood (elastic modulus, bending strength and density) were studied on Douglas fir ((Pseudotsuga...

Intensifying the use of forest biomass to produce fuelwood, through the removal of harvest residues or reductions in rotation length, increases nutrient outputs and can ultimately lead to reduced soil fertility. We developed a modelling approach for the evaluation of different forest management...

Context: Tree species selection is one of the most important forest management decisions to enhance forest productivity and stand stability on a given site. Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii), a non-native species from north-western America, is seen as an important...

In the context of questioning the relevance of making Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) silviculture more dynamic in Wallonia, we evaluated the influence of growth rate on the potential of Douglas-fir lumber for structural uses. Therefore, six trees 120 to 180 cm in circumference...

Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) is the most common utilized introduced tree species in the temperate zone, planted in many European countries. Also, in the Czech Republic it represents the most planted exotic species as well. Its planted area exceeds 6,000 ha and represents 0.25% ...

Taiwan has a long history of reforesting degraded forest lands and reclaimed agricultural lands to improve forest ecosystem services. While the effort has been ongoing since 1950's, very few studies attempted to understand how tree species planted on these lands are growing. To fill the knowledge...

In response to changes in forest management and conversion practices, concern has arisen that some solid wood products manufactured today exhibit decreased strength and stiffness properties (modulus of rupture [MOR] and modulus of elasticity [MOE]) compared with those manufactured in the past. This ...

Tree species diversity can positively affect the multifunctionality of forests. This is why conifer monocultures of Scots pine and Norway spruce, widely promoted in Central Europe since the 18th and 19th century, are currently converted into mixed stands with naturally dominant European beech....

In the Pacific Northwest, the use of forest vegetation management (FVM) and seedling stock type selection are important tools to ensure seedling establishment according to organizational objectives and state laws. Individually, these two reforestation decisions have been shown to increase growth...

Commercial thinning (CT) is an important tool that meets a diverse set of forest management objectives, including the generation of intermediate revenue, promotion of regeneration tree growth, and the modification of vertical and horizontal fuel structure for wildfire mitigation. Using a set of 653 ...
