Changes in the steppe vegetation of the solitary conic hill Oblík in the České Středohoří Protected Landscape Area
Zmeškalová, Jana ; Suchara, Ivan (advisor) ; Chýlová, Tereza (referee)
Změny stepní vegetace v NPR Oblík 8 2. Abstract Changes in the steppe vegetation of the solitary conic hill Oblík in the České Středohoří Protected Landscape Area This diploma thesis is based on a comparison of vegetation and chemical attributes of the soil between the years 1973 and 2006/7 in the model area of the Oblík hill. The primary source of old botanical and pedological data is a series of diploma theses by students from the Department of Botany, Faculty of Science, Charles University from the seventies of the 20th Century (Březinová 1973, Klimešová 1973, Suchara 1974). The study is limited by old methodology. Vegetation data were compared on the different levels - phytosociological relevés, non-destructive estimation of shrub biomass, photogrammetry of shrub communities and syntaxonomical classification. Environmental changes were studied by repeating chemical analyses (contents of N, C, K, Ca, C/N, pH) and indirectly using Ellenberg's indication values. Today, there is higher species diversity and a high turnover of species in the area. The number of pastures and mesophilous broad-leaved grassland species has decreased. The number of nitrophilous and margin species, weeds and shrubs has increased. The area of the syntaxonomical units Festuco valesiacae-Stipetum capillatae, Koelerio...
