Projekt zalesnění kalamitních holin na území LS LČR Rožnov pod Radhoštěm
Sobotka, Milan
The aim of this thesis is to prepare a complex project of regeneration of the calamity clearing in the Rožnov district. The district is under the administration of the Forests of the Czech Republic (LČR) state enterprise, more specifically under the Rožnov pod Radhoštěm Forest Administration. The project addresses the beginning of the change of the species composition in selected stands on 3 large calamity clearings resulting from salvage logging with the long-term aim to create stands of the original species composition. The total area of these calamity clearings is 65,42 ha. Extensive planting will take place between 2019 and 2023. Within project activities, the whole area will be planted with a wide range of tree species. Other parts of the project include follow-up activities that address the initial protection of planted stands. This will consist in mechanical and chemical protection against wildlife damage and protection against weed pressure. The last part of the project is an adjustment of the composition of growing stands by cutting pioneer species. Direct economic costs are processed as part of the project.

Návrh obnovy lesa v oblasti chřadnutí lesních dřevin
Hoferek, Petr
The main aim of the bachelor’s thesis was to find out in what way and in what extent the process of the withering of spruce cover goes on in the area of Lhotka u Zlína, and to propose the change of composition of tree species together with its distribution in space (monoculture, polyculture), depending on the state of the forest stands. The method of forest regeneration, treatment, and the protection against biotic pests of the forest plantations was planned, till the time of provision. Proposals for the forest regeneration also include layout of transplants. The work also includes calculation of direct economic costs of the proposed methods and attachments including a map of the target area of LHC and photo documentation. The outcome of the project will be greater representation of a deciduous woody species and diversity in tree species composition. The spruce will be replaced by douglas-fir. In the future, there will be an intention to regeneration via shelterwood cutting in this area.

Projekt zalesnění kalamitních holin na území LS LČR Vítkov
Valíček, Jakub
The aim of this diploma thesis is to elaborate a complex project of restoration of clearing due to salvage felling in the forest district Odry and reconstruction of the spruce in the district of Heřmánky. The forest districts are under the administration of the state enterprise Forests of the Czech Republic, specifically under the Forest Administration of Vítkov. The project includes an analysis of causes of declining and dying stands in the selected area, stand condition, condition of clearings and young plantations, site preparation, methods of woody species and methods of recovery, protective and defensive methods of established plantation, direct economic costs.

Rozsah, postavení a odrůstání jeřábu ptačího (Sorbus aucuparia L.) v Krkonošském národním parku
Koulová, Ladislava
The work was developed on the territory of the Giant Mountains National Park. The main objective was to determine the extent and the growth of bird crane in all levels for the whole NP. The measurements were carried out in the selected area of Horní Maršov, where several dozens of stands were visited and the JR was measured and registered. The game damage, height, thickness, position in the stand, representation and impact of the crane occurrence were evaluated. At the same time a detailed analysis of the crane output in the stands was carried out. of the KRNAP and the interest LHC. The crane is mainly found in lighted hedges, in pots and in places where there is no high pressure from the boar. There was no detectable difference in the growth in acidic and rich habitats. In dark SM cultures and BK stands, the recovery of JR does not occur. On the first floor there are cranes under SM stands in combination with BR and SM raids, some locations also show BK. In these phases, the crane is strongly attacked by animals that reduce growth and vitality. At a height of 3 meters, the JR is already grown for the game, reaching the second level. In the third floor there are already grown individuals. The Forest Economic Analysis analysis showed that crane representation is higher than the available literature. This may be due to purposeful management and accidental mining. The results of the in-depth investigation continue to indicate that the crane as a pioneering tree is alternated by spruce and beech within a large development cycle.

Comparison of forest stands on afforested agricultural vs. continuously forested soil
Květoň, David ; Podrázský, Vilém (advisor) ; Jiří, Jiří (referee)
There are many differences between environment of woodlands on afforested agricultural lands and continuously forested soils. These differences are able to persist for many years after afforestation. It is anticipated differences in the growth and condition of these stands. This thesis deals with these differences and aims to compare them. There were compare differences between spruce stands and larch stands and differences between thickness of overlying humus in four plots of the size 0,25 ha, in the area laying near to village Brložec, in region of Karlovy Vary. Results moreless confirm a greater production of both species of trees on former agricultural lands, they indicate greater production potential of larch compared with spruce and they clearly show thicker humus to continuously forested areas.

Growth of young forest stands on afforested agricultural land
Hnilička, Libor ; Podrázský, Vilém (advisor) ; Holubík, Ondřej (referee)
This diploma thesis deals with the evaluation of mortality and initial growth of the cultures of forest trees on a afforested agricultural land and assessing the nutritional status of studied forest tree species. Research plots were established near the village Radešín (Pribram district) in stands of spruce, pine, oak and ash growing on former permanent grassland.
The results show that the stands of spruce, pine and oak on the examined habitats thrive very well. Four year old spruce and oak stands shows signs of secured culture. Using leaf analyzes the nutrition of these cultures evaluated as redundant. sAshen stand was attacked by a fungal pathogen Chalara fraxinea during the growth. The landowners were recommended to reconstruct extensive the stand.
