HORIZONTAL DISTRIBUTION OF THE YOUNG GENERATION OF TREES IN FIR-BEECH (ABIES ALBA MILL., FAGUS SYLVATICA L.) STANDS DEVELOPED WITH THE IMPROVED GRADUAL GROUP CUTTING SYSTEM

Keywords: distribution of trees, Carpathian beech forest, undergrowth layer, beech, fir, improved gradual group cutting system
Abstract: This study concerns the analysis of the type of horizontal distribution of trees in fir and beech undergrowth layer, growing under the canopy of two-generation felling stand. The purpose of the analysis was to investigate the spatial structure (horizontal distribution) of young generation in conditions of the improved gradual group cutting (IVd), as well as the evaluation of the applied regeneration method. The direction of further regeneration development was observed, too. Material was collected in 2001 from the area located in Krasiczyn Forest Division (Regional Direction of the State Forests in Krosno) in five two-generation fir-beech stands. The analysis was performed on 23 test plots. Size of each plot was 0.04 ha. Obtained results allow to evaluate positively the applied way of forest regeneration in the investigated stands. The improved gradual group cutting system assures the appropriate conditions of growth and development for beech at the proper group arrangement of trees in the Carpathian beech forest, which was observed very often in the undergrowth layer of this species. In case of fir-undergrowth trees generally charac-terized with random distribution. It seems to confirm the author’s opinion that fir can be only an admixture in Dentario glandulosae-Fagetum association. However, applied cut-ting system (IVd) creates the suitable conditions for artificial regeneration of this species in groups. It perfectly realizes the postulates of natural direction of silviculture.
