The issue of thesis is problematics of regeneration processes in forest stands affected by wind-calamity, which are managed under close-to-nature forestry principles – PRO SILVA. Research objects were 8 forest stands in Forest management unit Jelšava, where was created a series of permanent research plots – two of them in each stand, one without mother-stand residues, second one with them. There were selected homogenous beech forest stands and mixed beech-oak stands in two categories – up to 100 years and over 100 years. In the selected forest stands were measured basic dendrometric values. Based on the obtained data, there were analysed regeneration processes, diameter and height structure, usage of production space and state of the canopy closure. Most of the primary stands were in the rebuild-process to multi-storey forest stands. Nevertheless, the results of the analysis may conclude that in the stands was located viable natural regeneration, which creates basis for future forest stands and residues of mother-stand create a presumption of natural regeneration refill.
