Struktura a dynamika přirozené obnovy po skupinové seči ve smíšeném lese na ŠLP Křtiny
 Bíšek, Tomáš
The aim of the work was to evaluate the dynamics and structure of natural forests regeneration in finer (small-scale) management systems and optimize silvicultural (regeneration) operations. For the research were selected three stand types (beech, spruce and mixed), into which were placed 10 group cutting. There were analyzed light conditions, herb layer, density and regeneration parameters. The density of regeneration were analyzed according to the light conditions and position in the group cutting. From the measurements it was found that natural forests regeneration most easily proceeded in a spruce stand type. In these conditions it was achieved less diversity of tree species, the highest was recorded in gaps mixed. Compared small gaps (0.05 ha) and large gaps (0.05 to 0.13 ha) higher densities forests regeneration has been measured in large gaps. Diversity of trees inside the gap corresponds to the light conditions of wood. In the central part prevailed larch, in the transition under the forest wall of shelterwood prevailed spruce and beech. Under the protection of the surrounding stand fir is the best regeneration. Regeneration of species surveyed are oriented to the west, south and east exposure gaps. This fact corresponds to the superiority of Indirect Site Factor (ISF). The results of this study show that at any given time at a given location can be group felling increase species diversity forests regeneration.
