The paper analyses the impact of tree species (Norway spruce, silver fir) and height position of the tree on its diameter increment and crown efficiency in a selection forest of Oravské Beskydy Mts. The results have confirmed great variability of the stem diameter increment, that ranges from 0.39 to 10.83 mm per year. In the lower tree layer the diameter increment of Norway spruce is distinctively smaller in comparison to that of shade-bearing silver fir. However generally (regardless of tree layer) the impact of tree species is not significant. The results have revealed the tree layer has no significant influence on the stem diameter increment as well. The reason of this is an excessive harvesting of upper layer trees, that has a positive impact on diameter increment of Norway spruce and silver fir individuals in the lower and middle layer of the selection forest. The crown production efficiency of Norway spruce is lower in comparison to the silver fir. For the equal basal area increment Norway spruce needs approximately 30% (upper layer trees) to 60% (lower layer trees) larger crown surface area than the silver fir. |
