Forest soil acidification in the Czech Republic and analysis of differences between spruce and beech stands
Růžek, Michal ; Chuman, Tomáš (advisor) ; Romportl, Dušan (referee)
Forest soil acidification in the Czech republic and analysis of differences between spruce and beech stands Abstract Acidification of forest soils is the process which considerably affected soil chemistry in the 2nd half of the last century. The aim of this paper is to give comprehensive review about the soil acidification, especially with focus on differences between forest species Norway spruce (Picea abies) and beech (Fagus sylvatica). The work also provides information about acidification mechanisms and its historical development in the Czech Republic. In the practical part the soil conditions under the beech and spruce stands from 5 mountainous and upland sites are compared. The results showed better soil conditions under the beech stands, where higher pH values and concentrations of base cations were measured. However there were observed lower concentrations of toxic Al3+ in deeper horizons under the spruce stands, although the difference was insignificant. key words: soil acidification, spruce stands, beech stands, Czech Republic

Remote sensing for evalution of state and development of Spruce stands condition in the Giant Mountains
Musilová, Romana ; Kupková, Lucie (advisor) ; Štych, Přemysl (referee)
Bc. Romana Musilová: Využití dat DPZ pro hodnocení aktuálního stavu a vývoje smrkových porostů v Krkonoších Remote sensing for evaluation of state and development of Spruce stands condition in the Giant Mountains Abstract Monitoring the health status of forest areas using remote sensing methods are still under development. This master thesis focuses on the use of SPOT, Landsat, QuickBird and WorldView-2 images to evaluate condition of spruce stands in Giant Mountains National Park. For these purposes were selected vegetation indices available in the lite- rature. First satellite images were preprocessed and subsequently calculated vegetation indices. From the generally known were used Normalized Difference Vegetation Index, leaf area index and Simple Ratio. Than were calculated Green Vegetation Index and Red Green Index based on the monitoring of needles color changes. To evaluate moistu- re conditions were used indices Foliar Moisture Index and wide-band Normalized Diffe- rential Infrared Index. The goal was a comparison of the results of these indices and assessment of their applicability. Map outputs indices were compared with maps of de- foliation and mortality of coniferous stands by Ing. Milan Stoklasa. Keywords: remote sensing, Norway Spruce stands, Giant Mountains, vegetation indi- ces, SPOT,...

Obnova lesa na kalamitních holinách VLS, s.p., divize Lipník nad Bečvou, LS Hlubočky
Provazníková, Pavla
The aim of the dissertation was to analyze the state of cultures in bare areas incurred by the withering away of spruce growth. The dissertation was undertaken on the properties of VLS ČR, s. p., in the economic forest unit of Hlubočky and Bores. The monitoring took place in 18 research areas which were afforested between the years 2007-2015, where 9 areas were afforested with Norway spruce and 9 with European beech. The height of the over ground part and the thickness of the root crown were measured and the presence of damage caused by wild game was evaluated. The monitoring for the purpose of establishing the state of the young spruce and beech growth took place in 10-15 year old growth areas where the trees per hectare, damage by wild game and the percentage of defoliation were evaluated. The third aim of this work was the framework evaluation of the afforestation costs and the care of the cultures according to data from forest management accounting. The monitoring of research areas afforested between the years 2007-2015 found that beech plants were more damaged by browsing than spruce plants. The monitoring of young spruce and beech growth established more damage of the young spruce plants by deer barking and browsing rather than the young beech plants, which are healthier. It was further discovered that the beech growth from natural renewal, which are thicker, are less damaged by wild animals. The evaluation of data from the forest management accounting established that the costs for one renewed hectare on average amount to CZK 64,000, the treatment of one hectare against forest weeds on average cost CZK 9,700 and the protection of one hectare against wild game expends on average CZK 3,470.

Stanovištní charakteristika nosatcovitých v bukových a smrkových ekosystémech Moravskoslezských Beskyd
Hrabovský, Karel
Title of the diploma´s thesis: Habitat characteristics weevils in beech and spruce forest ecosystems Moravian-Silesian Beskydy In forest ecosystems Moravskoslezské Beskydy was conducted from 2007 to 2015 collection epigeic fauna using ground traps. Trapping took place at 6-week inter-vals from May to October. Family (Curculionidae) was evaluated in beech spruce stands using faunistic index in relation to the basic typological units which are forest vegetation zones (LVS), edaphic category (EK), forest type (SLT) and ecotope conditions such as soil type, soil chemistry, humus form and composition of the herb layer. Incidence was compared of Curculionidae in selected nature reserves in silviculture stands. Total were captured 26,743 individuals of Curculionidae amount of 52 species. Eudominant species are Otiorhynchus carinatopunctatus, Plinthus tischeri, Otiorhynchus tenebricosus, Rhinomias forticornis and Strophosoma melanogrammum. In Beskydy they were captured rare species Barynotus moerens and Barypeithes mollicomus. It was found continuity of some species of Curculionidae on forest vegetation zones (LVS), edaphic categories (EK) and continuity some species of Curcilionidae on soil attribute.

Zhodnocení dopadů sucha v roce 2015 na lesní porosty na revíru Dzbel, část Zadní hory, Lesní správa Prostějov LČR
Pospíšilová, Lucie
The forests are very susceptible to the climate changes, because they are not able to adapt quickly to the changes of the environment due to their longevity. The drought belongs to the group of primary abiotic factors, which significantly affect the health condition of the stands and thus also the extent of salvage logging. This diploma thesis evaluates the impact of extreme drought in 2015 on the stands of the forest area named Zadní hory (close to the town of Dzbel, Forest administration Prostějov). The most endangered tree species is the spruce, due to it´s predominant occurrence in the mentioned area. This work should evaluate the effect of both abiotics and biotics stressors on the drougt-weakened stands and suggest the options for reduction of the damages.

Historical development of stands in the first zone of the National Park Šumava close to the village Prášily
Strnad, Jiří ; Šálek, Lubomír (advisor) ; Zahradník, Daniel (referee)
The dissertation, The History of Evolution of the Forests of the Category I Protected Area in the National Park Šumava- environs of the municipality of Prášily, firstly focuses on the research and analysis of extant historical documents and other archival materials. In particular it analyses the historical maps of the former Velkostatek Prášily-Dlouhá Ves of the Schwarzenbergs family that show the evolution of the forests and their management between 1860 and 1930.
Secondly, the dissertation focuses on the assessment of the current state of the forests and the way in which they are managed by the Správa NP Šumava and in particular on the positioning of the category I protected areas in order to protect the remnants of the native woodland.
