Zhodnocení výskytu a kvality výstavkových stromů na území demonstračního objektu porostů v převodu na střední les na ŠLP ML Křtiny
Vaníček, Lukáš
The main objective of this thesis is to evaluate occurrence and quality of Standard trees on the territory of 59 ha of Demonstration object of forest stands in transition to coppice-with-standards forestry; and to propose forest restoration using Standard trees. During field research, following parameters for Standard trees were collected: coordinates, DBH, crown height placement, tree height, quality. During data processing, following parameters were added: forest compartment identification, set of forest types, exposure, Standard tree trunk volume. Standard trees were most often found in 2S and 2C types. Quality of Standard trees was most often labelled as C or D. Largest volume was found for set of forest types 2D and 2H, smallest volume in set of forest types 1J and 1Z. In order to propose forest restoration, 8 x 0,5 ha square sample plots were established in forest types 2C an 2S. On these particular plots, DBH cross-calipering and harvesting intervention was carried out.

Vliv stanoviště a kvality výsadby na odrůstání kultur dubu letního
Vaníček, Lukáš
The aim of the thesis is to find out the impact of the forest stand and the quality of the planting on the growth of Quercus Robur L cultures. For this purpose there was found 10 research forest plots at forest habitat types 3K, 4K, 3S, 3C, 3L, 3P situated in LS LČR Jeseník area. In 2014, a bare-root variant of Quercus Robur L seedlings was planted in each research plots using slot planting. In each research area, several parameters and traits of the above-ground part were detected in 100 individuals, and the root system was dug and analyzed in six individuals on each research area. After the end of the vegetation period in 2018, the above-ground part was measured, the following parameters and features were examined: height of the above ground part, height increment, lateral increment, root neck thickness, trunk ripple, trunk deviation the size and color of the assimilation apparatus, the damage of the cultures by biotic and abiotic factors. Root systems have been evaluated for root depth, main root length, incidence of stumbling, absence of stakes or panohs, and p-index value. The results clarify that culture at nutrient and water-enriched habitats have better vitality. The worst results were found by 4K forest type.
