Effect of Trampling on the Vegetation of Dry Grasslands
 Vacková, Nikol ; Horčičková, Eva (advisor) ; Husáková, Iveta (referee)
1 It has been proved that the effect of vegetation trampling (Anthropogenic and animal) significantly changed. The aim of this study was to gather available information of these changes and effects of secondary factors, particularly focusing on the dry-grasslands (Festuco-Brometea). Vegetation on trampling disturbed areas is already much lower, it has less vegetation cover and there is more bare soil. On the bare soils increases temperature and greater evaporation of water. Due to changes of climatic conditions of microhabitats the diversity of species is changing. Vegetation is not changed only on the trampling trails, but also in the surrounding area, up to a distance of 2 meters from the trail. Most vulnerable to trampling and most susceptible for changes in vegetation are moist habitats, the most resistant type of vegetation is thermophilic dry-grasslands. The behavior, abundance and intensity of browsing animals have also effect on vegetation changes. Animals during their browsing vegetation disperse seeds and plants spread beyond their natural occurance.
