Vliv půdních vlastností na genezi vegetačních typů spontánně regenerovaných a lesnicky rekultivovaných ploch ve vápencovém lomu Mokrá
Cihlářová, Hana
The role of soil properties for the vegetation development during early spontaneous succession and forest reclamation was studied in a limestone quarry Mokrá (south of Moravia). Spontaneously regenerated areas were studied mainly with the aim to detect the soil environment features supporting the swards formation of expansive reed grass (Calamagrostis epigejos), which is able to arrest a succession process. Forestry reclaimed areas were study with the aim to compare soil properties of prosperous and decline sites. We examined water air regime, soil reaction (pH), soil texture, soil organic carbon content (SOC), total nitrogen content (Ntot) and content of available Ca, Mg, K and P. The multivariate statistical approach revealed the fact that soil texture, SOC, Ntot and water air regime were statistically significant for the spontaneously regenerated vegetation types. Reed grass preferred fine grained soils with higher SOC and Ntot content. Content of clay, sand and available K were statistically significant for decline and prosperous sampling sites. However any soil property could be called as a cause of prosperity or decline.
Uchycení vybraných pozdně sukcesních a nepůvodních druhů dřevin na lesnicky rekultivovaných a spontánních posttěžebních stanovištích
PROŠKOVÁ, Miloslava
This study compared the establishment of late successional and alien woody species in different stages (young, middle, late) using two restoration approaches (spontaneous succession and forestry reclamation). The experiment was carried out in the sand pits situated in Třeboňsko Protected Landscape Area.
Taxonomic review Pinus contorta subsp. Latifolia (Engelm.) on dumps habitats and possibilities its usage
Vanc, Ondřej ; Kunt, Miroslav (advisor) ; Konstantin, Konstantin (referee)
Lodgepole pine is exotic species of pine originating from North America (Canada, United States, United Mexican States), where it occurs along the Pacific coast. This is a very compatible species because, despite a plethora of geomorphological habitats has created a total of five subspecies, while the Czech Republic there are three of them. They are: Shore pine (Pinus contorta subsp. contorta), Lodgepole pine (Pinus contorta subsp. latifolia), Murray pine (Pinus contorta subsp. murrayana). Occurrence of Pinus contorta was recorded in nine counties, twenty and twenty-three districts of municipalities with extended powers. The total stand area was found to 128.66 hectares. When finding that Pinus contorta in our conditions is described as exotic plants. As a gateway for non-native landscape landscape that is post-mining areas. Use of Lodgepole pine was thus deemed appropriate. Uncultured landscape together with wood unoriginal see to it that the uncultured landscape becomes a landscape rich in diversity. Lodgepole pine, of course, is not the only species that was about it all taken care of. Its suitability was chosen because of its low demands on soil, hydrological and climatic conditions, including frost hollows at elevations 2,500 meters above sea level. Which in the Czech Republic or cannot be used because it is our highest point 1,602 meters above sea level. The effort was to map Lodgepole pine throughout the Czech Republic, where it would be clearly seen where the forest vegetation on which the administrative territory of the Lodgepole pine occur. This reliance on the willingness of administrators data information, which for our purposes were considered Institute of Forest Management, where we were given virtually everything to us this institution has been able to provide. Another institution, where we were given also all the military management of forests and farms. Unfortunately, the state enterprise Forestry of the Czech Republic, as majority owner of primary forests in the Czech Republic, was not willing to provide the requested information on the matter on Lodgepole pine, forest management Děčín only the necessary information. Given that this work was originally conceived to Pinus contorta subsp. latifolia, while work was concluded that Pinus contorta subsp. latifolia is a segmentation occurring geographic subspecies that was not able to clearly identify the data that we had available so this work deals with Lodgepole pine at the species level and the resulting map outputs in the results of the work 7 were processed in the geographic information systems, which managed to get stand up to the level surface (ha) in the regions of municipalities with extended powers.
Vyhodnocení úspěšnosti lesnické rekultivace po těžbě černého uhlí v okolí Orlové
Cagašová, Kateřina
The present bachelor thesis is aimed at success rate evaluation of forestry re-cultivation in selected territories in the surroundings of the town Orlová and suggesting contingent measures thanks to which, it could be possible to improve the approach to technological re-cultivations followed by biological ones within the treatment of territories affected by underground coal mining. The evaluation paid special attention to an assessment of the site preparation before planting, woody plants used, crop and cover care, losses, length of the above-ground part and thickness of the trunk, tree-top and trunk shape, its vitality and impairments. The follow-up measures took into consideration specific features of the site and conditions of perspective growth of woody plants. The study exploited available materials and documentations which had been compiled since the beginning of planning of the re-cultivations themselves. Further findings were completed by measuring relevant dendrometrical values on the woody plants proper and through analysis of the site. Based on the evaluation of individual site researches there was a description of the present state of the covers done, their quality was assessed and suggestions of measures for the follow-up care were submitted. This study also pointed out some inconvenient steps including not always correct selection of the woody plant kinds, which did not take into proper consideration existing growth conditions in sites that had been formed from non equal landfillings of slag and topsoil with some of the re-cultivation events. In the end there was an evaluation of the accomplished technological actions performed in relation to the composition of species of the woody plants and the following planting thereof including suggestions of measures leading to improvements of quality of plantings and thus achieving quality target cover.
