Impact of orography and stand canopy on stand volume in pure uneven-aged beech stands

European beech is one of the most important and most common tree species in Europe, which have extremely wide amplitude in sense of horizontal and vertical distribution. In Serbia and Bosnia and Herzegovina European beech (Fagus sylvatica L.) represents one of the most important tree species from an economic and ecological point of view, because it's constituting significant areas of highly productive pure and mixed forests. The main goal of this research is to determine the influence of orography (slope, aspect, elevation, and spatial distribution-climate zone) and one stand characteristic (canopy) on stand volume in pure uneven-aged beech stands. The existence of the aforementioned influence was analyzed using multi-factor ANOVA (Type II sums of squares). The research was conducted on 20 localities (grouped in 3 climatic zones). One in the eastern part of Serbia on 8 localities (Moesian province), second in the eastern part of Republika Srpska on 7 localities (Illyrian-Moesian province), and third in the northwestern part of Republika Srpska on 5 localities (Illyrian province). The obtained results showed that only slope (p≤0.1) and canopy (p≤0.001) have a statistically significant impact on stand volume in pure beech stands.
