Silver fir is one of the longest living and tallest trees in Europe, it has major commercial importance and may be found in various communities predominantly connected with lower mountainous locations...
In this paper, site-specific allometric biomass models were developed for European beech (Fagus sylvatica L.) and silver fir (Abies alba Mill.) to estimate the aboveground biomass in inca virgin?fores...
Research Highlights: In mixed stands, competitive and supportive relationships occur between trees, illustrated by their dendrometric characteristics. Background and Objectives: We investigated the ef...
Recently, increasing attention has been paid to the anthropogenic degradation of the riverbed and its relationship to the ecological status of the adjacent river landscape. The key objective of this r...
The European beech (Fagus sylvatica L.) is a competitive and shade-tolerant species, with its natural regeneration in closed-canopy stands affected by a number of variables. The study aimed to identif...
This study was carried out to evaluate gap characteristics and gapmakers for different development stages of an oriental beech forest in northern Iran. Development stages of 1 ha square-shaped mosaic...
Crop trees are the main bearers of qualitative and value production of the stands. Although the number and production of the mentioned trees are affected by various factors, crown development by means...
Experimental results from the first thinning in mixed stands are not broadly experienced by forestry practice. To extend the experience with the thinning of a mixed stand, we studied thinned and unth...
The present study has been done to evaluate the impact of pure ash stand and mixed stand with beech on the herb layer biodiversity and soil properties in the forests of Noor city. There is a unique s...
Horizontal structure of forest stands largely affects the competitive relationships between tree individuals and plays a significant role in the stand dynamics. The present study describes horizontal ...
The study analyses the chemical properties of the soil in open-canopy beech stands in relation to the predominant species of ground vegetation. A hypothesis is examined whether the predominant ground ...
We present the results of research on diameter increment in beech stands in the area of Hostynské and Vsetínské vrchy. The data were collected on three series of permanent research plots (PRP) in midd...
The visual impact of primary landscape is overwritten, historical references and spiritual ties to the current local population are losing. Rational planning and evaluation of the landscape must corre...
Pitfall traps were used to capture 3,550 individuals and 34 species of Myriapoda in five pairs of Norway spruce and beech stands in the  Moravskoslezské Beskydy Mts. (Czech Republic). Diff...
The investigation of the hydrothermal exposure effect on the glue-line strength is obvious when outdoor application of wood products is in option.
