The main aim of this thesis is evaluation of the growth of European silver fir (Abies alba Mill.) and nursery woody species at initial stage of regeneration on calamity originated clear-cut. For this purpose were established experimental areas TVP Rakovec (ŠLP Křtiny) and TVP Tornádo (LČR LS Albrechtice city). These areas have been divided into smaller plots, where the regeneration of European silver fir was carried out concurrently with regeneration of White birch (Betula pendula Roth.), Black alder (Alnus glutinosa L.) and European aspen (Populus tremula L.) in spring 2014 and autumn 2015. The growth of European silver fir and nursery woody species was evaluated according to the height, diameter of root crown and mortality. In area of TVP Tornado the most successful manner was concurrent regeneration with birch, under which fir reached average height of 47 cm just after two years of growth and where the mortality was only 1,4 %. In case of this manner, the birch reached the height of 251 cm and 37 mm in diameter of the root crown. In area of TVP Rakovec the best growth of fir occurred under the European aspen and reached average height of 40 cm. Contrary, in case of this manner was the loss of the fir, exactly 26,2 %. The most successful nursery woody species in area of TVP Rakovec was the Black alder, where occurred much fewer losses and reached the best results of the growth. Within this diploma thesis was also made theoretical analysis of the nursery stand ability of production, in which have been found out that the European aspen has the highest production potential in all bonitet and the Black alder has the smallest production potential in compare with all chosen nursery woody species. Within both areas of research have been investigated the influence of the nursery stand in initial stage to the microclimate of calamity originated clear-cut. The impact hasn´t been confirmed.
