Growth performance of common-sized planting stock and saplings after plantation on forest sites
Kaiser, Josef ; Kuneš, Ivan (advisor) ; Tužinský, Marek (referee)
The clear-cut area which is afforested in the Czech Republic is around 20 th. hectares large annually. In the last decades, we have observed frequent periods of the spring and late summer drought, which significantly negatively influence survival of the reglarly used transplants (RUT) however. Thus, it is necessary to search methods, which can decrease such losses. One possiblity how to solve this problém is to used containered transplants, the second one is the use of the plant material (PM) of bigger size (semi-large-sized=SLSPS and large-sized planted stock=LSPS). These larger plants are more resistant to unsuitable influences of environment than the RUT. The advantage of SLSPS and LSPS is also shorter time of necessary care to plants and lower costs to secure plants in comparison to RUT. Above mentioned facts were taken into consideration in creation of instructions for my bachelor thesis. The goal was to estimate the parameters of mortality and growth of selected various PM, moreover on sites heavily influenced by human activities. As model trees were selected: oak (Quercus robur) and lime (Tilia cordata). PM was generally bare-rooted (RUT, SLSPS and LSPS) and planting was done by mechanize equipment (into bored holes) at study sites Truba (Kostelec nad Černými lesy) and Hůrka (Planá nad Lužnicí). The first part of experiment was established at Truba on area of former forest nursery and cosisted of lime RUT and LSPS, the second one was established at site Hůrka in area of former sand querry, where RUT, and oak and lime SLSPS and LSPS were used. No one site was moved during experiments. The measurement on Truba was repeated on spring and on autumn 2012-15 and in 2015 on Hůrka. The height of PM was evaluated by using scale lath, the thickness of stem was measured above ground by using digital scale. Subsequently, data were evaluated in Excel and statistically tested by Kruskal-Wallis test. The results indicate, that mortality of RUT at Truba is 5 times larger than that of LSPS. The similar result was obtained also at Hůrka, the mortality of lime RUT was twice larger than in case of LSPS however. The lowest mortality was observed surprisely on SLSPS. The comparison of the oak RUT and LSPS indicated no any differences in mortality. The mortality of oak PM was generally significantly lover than lime PM one. Statistical tests also indicated, that the size of study sets of PM was too low for optimal scientific evaluation of selected parameters. The obtained results also indicate, that important factor, which influences mortality must be (apart from type of the PM) also additional, non-defined factors of environment up to now.

The memorable trees of Melnik (Czech Republic)
Koprnická, Lucie ; Skalický, Milan (advisor) ; Martinková, Jaroslava (referee)
The theme of this thesis are memorabl trees, the Melnik, a town in the Central Region. The work is divided into theoretical part, which is drawn primarily from scientific publications, existing laws and regulations, as well as from the pages AOPK CZ and from information provided by the Municipal Bureau of Melnik. The theoretical part describes the history of the protection and protected trees in the Czech Republic, legislation protected trees, mensurational parameters described below are the most common defects of trees and there is general information on the care of memorial trees. The research deals with seven memorable trees in Melnik. This section focuses on the review and assessment of the health status of selected memorial trees, state sign, characteristic of their territory, to determine the owner of the tree and photographs. At the end of the work are author readings, comparing the values of previous measurements, and then there is the evaluation of the current status of protected trees in Melnik. The conclusion of this work is the management of protected trees and the care provided is drawn trees Melnik and suggestions for other recommended measures for these memorial trees.
