Vyhodnocení úspěšnosti obnovy lesa na kalamitních holinách LS LČR Jablunkov

This work deals with artificial regeneration of the forest on the calamity clearing areas LCR LS Jablunkov. The main objective of this bachelor thesis was to evaluate the growth development of 5-8 years aged plantations of Norway spruce, silver fir, European Beech, pedunculated oak, small-leaved lime tree and black alder, after planting at water-affected sites. The other objective was to compare the results with growth at nutrient sites. The following parameters were evaluated: Losses, length of the shoot, last increment, diameter of the root collar, length of the needles, size of the assimilation apparatus of leaves, color of the needles, damaging, warp of the stem, vertical deflection of the stem, deployment height of forked trees, stem form and shape of the crown. Evaluation of trees´ root system was also part of this work. Results showed, that black alder and Norway spruce grow the best at the water-affected sites. Planting of small-leaved lime tree and pedunculated oak didn´t approve, on the contrary. Another problem was the fact, that there were serious deformations of the root system at all tree species. The last issue were the high losses due to the poor quality of the planting stock, improper way of planting, and large number of the occurring game. The comparison between water-affected and nutrient sites shows, that the trees grow better and reach better parametres and smaller losses at the nutrient sites
