The diploma thesis aim was analysis of established plantation Silver fir, European beech and natural regeneration of other tree species to Training Forest District Hůrky, Secondary Forestry School Písek. It was after bark beetle disaster. This diploma thesis goes from bachelor thesis: Evaluation of the artificial regeneration of Silver fir and European beech at Training Forest District Hůrky, Secondary Forestry School Písek. Density, share, height, root colar diameter, last increment of height and losses each tree species was find out within stand. 3120 trees was measured in 2013. It is about 467 trees less than 2011. Natural regeneration Scots pine had the biggest losses (29,4 %). Probably it influence on competition. Total losses to artificial regeneration silver fir was 56 %, of which 1,6 % to last two years. The most prefer tree was Scots pine -- 33,4 % and Douglas fir 32,3 %. Silver fir had only 15,3 % from total share. Density trees (Scots pine, Douglas fir, silver fir, European beech, Norway spruce, European larch, sessile oak, cherry, white pine) was 16 830 pcs/ha. The higher height increment had sessile oak (70,1 cm), on the other hand lower height increment had Norway spruce (19,6 cm). Result of this measured is, that silver fir and European beech had not regenerated. Because natural regeneration was domination than artificial regeneration. In current time, it can states, that culture meet all parameters of established plantation.
