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.

Výskyt a hodnocení zdravotního stavu hlavních edifikátorů lesních porostů v oblasti Přírodní lesní oblasti č.16 Českomoravská vrchovina
Krajíčková, Dominika
In 2021, the representation of European beech (Fagus sylvatica) in the Czech Republic was 9.3 %, of maples 1.6 % and oaks 7.6 %. These values are slowly increasing, and the representation of European beech has increased by 3.3 % of the total area of arable land over the last five years (Zelená zpráva 2021). This work discusses the life manifestations of European beech (Fagus sylvatica), Norway maple (Acer platanoides), Sycamore maple (Acer pseudoplatanus) and Pedunculate oak (Quercus robur) in selected small protected areas in the Natural Forest Area No. 16 of the Czech-Moravian Highlands. The aim of this work is to evaluate the life manifestations of the above-mentioned tree species. Three small protected areas were selected, of which two localities are located in the 5th forest vegetation tier and one partially in the 5th and 4th forest vegetation tier, and endometrial measurements were performed here. The result was a comparison of the obtained data between individual sets of forest types and individual tree species on the set of forest types 5J. The diameter of the trunk and the height of the beech crown deployment were lower at 5K. The Norway maple reached smaller thicknesses at 5J compared to the other trees, on the contrary, the Sycamore maple and Pedunculate oak reached greater heights.

Zhodnocení rycí aktivity prasete divokého v lesním prostředí
Růžičková, Eliška
On 970 ha of the monitored area of Hodonínská Dúbrava, which includes the Hodonínská Dúbrava National Natural Monument, a field survey was carried out in the form of monitoring of wild boar (Sus scrofa) rooting in order to clarify the extent of the wild boar's impact on the forest ecosystem. The subject of the investigation were fresh wild boar rootings, therefore the monitoring was carried conducted after winter, in the spring of 2022. It was necessary to follow established lines evenly distributed over the area and each recorded fresh rooting was documented in the GPS device as well as in a spreadsheet. A total of 2,298 recordings were collected with detailed information on the rooting area, layer or for example vegetation cover. These data were supplemented with LHP data from the Forests of the Czech Republic followed by their evaluation. Wild boar largely preferred medium-aged pine stands and mature oak stands and its activities mainly affected forest types 1S and 1O. In majority of cases, the wild boar rooted to a depth of 25 cm and preferred the soil subtype Cambysem arenaceous. Distance from roads and watercourses became a significant factor in the intensity of rooting.

Beech and spruce forest stands conditions in the area of the Moravian-Silesian Beskids and soil zoocenosis
Bayer, Jakub
Soil epigeal fauna of beech and spruce forest stands had been monitored for 8 years (2007-2014) in 37 selected research area in the Moravian-Silesian Beskids. Collection of material carried out twice per year in spring and autumn aspects. Site characteristics of research localities were characterized by high variability while 4 vegetation altitudinal zones, 8 edaphic categories and 12 forest site types had been distinguished. Soil fauna was extracted by Tullgren devices. Within the monitoring, 11 target animal groups were engaged in: mites, springtails, larvae stages of ground beetles, symphylans, diplurans, proturans, centipedes and millipedes, larvae stages of rove beetles, adults of rove beetles, earthworms, larvae stages of click beetles (wireworms). Earthworm´s and wireworm´s cenosis were deterimined into species and genera, respectively. Remaing groups of soil fauna had been studied within larger systematic categories. Subsequently, abundance and dominance of the particular groups of soil epigeal fauna. The outputs had been compared each other and potential relations between particular animal groups to the specific site properties, vegetation altitudinal zones, edaphic categories and forest site types had been assessed thereby. Overall, 274 015 individuals were captured within the monitored soil animal groups. Several groups of soil cenosis were disvored specific relations to the site conditions. Additionally, 12 species of earthwomrs were distinguished while Dendrobaena octaedra seemed to be significantly dominant species representing 68,33 % of total earthworm´s species spectrum. Larvae stages of wireworms were determined into 5 genera. Representatives of Athous genera formed almost 86 % of the population of wireworms.

Možnosti a limity uplatnění prostokořenného a krytokořenného sadebního materiálu při obnově vybraných stanovišť středních a nižších lesních vegetačních stupňů
Bastl, Pavel
The aim of the bachelor thesis is a complex evaluation and comparison of the use of bare-root and container-grown planting material, with respect to planting and growth, so that the forest restoration would be more sucessful and effective. For this survey we set specific areas with suitable conditions related to habitat and altitude. The areas were located in particular forest types sets, specifically 4K, 4S, 3K, 3S, 3M. In each area we planted 200 bare-root and container-grown plants of European spruce (Picea abies L. Karst.), Douglas-fir (Pseudotsuga menziesii Mirb.) and European beech (Fagus sylvatica L.). The first finding in the following year after the forestation was a mortality. After the end of the vegetation period we evaluated 100 plants of each type and variety. The main measuring features included: the thickness of root neck, the height of above ground part, the mortality, the length of growth and other features that helped for the most accurate and objective comparison. Each variety and type of plants were measured, the data were evaluated and statistically compared.

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.

Kohout, Karel
The aim of bachelor thesis was to find out the positives and negatives of the use of containerized planting stock on different sites. For this evaluation, operational plantings were estabilished, that were planted with containerized planting stock. On the same sites, planting with the bare-rooted planting stock were evaluated. The following woody species were compared: Norway spruce (Picea abies (L.) Karsten), European beech (Fagus sylvatica L.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), silver fir (Abies alba Mill.), Scots pine (Pinus sylvestris L.), and European larch (Larix decidua Mill.). Each pair of plantings (with containerized and bare-rooted plants) has the same age and i tis on the same set of forest types (1K, 3B, 3S, 4B, 4S, 5K, 6S, 7K and 7P). It is evident from the achieved results that in 75% of the achieved results was better containerized planting stock.

Hodnocení objemového přírůstu v lese v převodu na les střední na majetku Městských lesů Moravský Krumlov
Kašpárková, Martina
This bachelor thesis deals with the volume growth of the sessile oak (Quercus petraea (Matt.) Liebl) in the forest in the conversion to the coppice with standards forest. The research areas are located on the property of Moravský Krumlov Municipal Forests. The aim of this work was to evaluate of volume increment of the standards depending on the stand age, the thinning intensity and the set of forest types. The analysis of the measured data was made in STATISTICA program. The tests showed a dependence of the increment on the thinning intensity and stand age. The most suitable variant of the combination of observed factors, where the volume increment was the largest, is the young stand with the set of forest types 2H, and a stronger intensity of thinning.

Vliv stanoviště na odrůstání prostokořenného a krytokořenného sadebního materiálu
Fojtík, Roman
The work was made in order to find out what influence it has on the growth of bare-rooted and cover-rooted material in habitats with a different set of forest types. The habitats were selected on forest type sets 3B, 3S, 4B, 5K and 5S. One research area was established at these sites, where the trees were researched for research: Norway spruce (Picea abies (L.) Karsten), European beech (Fagus sylvatica L.) and Douglas fir (Pseudotsuga menziesii (Mirb.) Franco). For this purpose, 200 individuals of bare-root varieties and 200 individuals of rooted varieties for each tree species were planted. When the growing season ended, data collection began in the field. Data collection was performed on 100 individuals from each variant. For the following comparison, the following parameters and features were ascertained: height of the aerial part, terminal flange, length of branch growth, root neck thickness, crown width, length of the assimilation apparatus, width of the assimilation apparatus, deflection of the stem axis, height of multiple stem deployment, color of the assimilation apparatus, ripple trunk, multiple trunk, crown shape, multiple peak, loss. Furthermore, the data were statistically evaluated and compared. This means that it could have an effect on the outgrowth of barefoot Douglas. This also applies to the rooted beech, except SLT 3S. The habitats with SLT 3B, 3S and 4B were better suited for the growth of bark-spruce, and on the site with SLT 5K and 5S there was a better influence on the growth of spruce.

Hudzieczek, Jaroslav
The aim of the diploma thesis was to find out the state and the evaluation of the growth of cultures and stands based on plowed and cryopreserved seedlings on LS Náměšť nad Oslavou. The results show the current state of cultures and stands at selected habitats. The results should contribute to improving the quality and success of the artificial restoration of the forest. For the research and the final evaluation, research areas were selected, which in each pair had the same year of founding (differing by half a year of spring / autumn planting), were found on the same set of forest types. Comparison of research areas differed with the type of planting material used (cryopreserved, flattened). The research areas were on these forest types: 4S (5x), 4K (4x), 4O (2x), 3S (4x), 3H (2x), 3K (2x), 2K (1x). On each research area the parameters were measured on 60 specimens of the tree. The main measured parameters included above ground height, growth, root neck thickness, length and width of the assimilation apparatus, and other parameters needed to refine and to compare objectively. The measured values were evaluated using the statistical method and were compared for each variant of planting material and wood species. The results showed that there is a difference in the growth and development of the cultures and stands based on the cryopreserved and trimmed planting material, in favor of the cryopreservation planting material.
