Sukcese vegetačního krytu na hlušinových odvalech v Ostravě
 Jaroš, Jakub
This thesis is focused on the evaluation of succession on spoil heap complex Petr Bezruč and spoil heap of the coking plant Svoboda since the last research carried by Koutecký (2004) and the care proposal of similar devastated sites. A total of 100 phytosociological relevés were made and 100 soil and 204 dendrochronological samples were taken on both sites. The analysis of the obtained data revealed identical changes of EIV on both sites, indicating the canopy increase of the tree species and alteration of the species composition, which was attributed to the ongoing succession. The difference among plots on spoil heaps and the difference among both spoil heaps was also evaluated. Spontaneous and directed succession was determined as the most appropriate means of restoration.

Sukcese vegetačního krytu na odvalu Koksovny Svoboda v Ostravě
 Jaroš, Jakub
This bachelor thesis is focused on the evaluation of succession on muck stack coking plant Svoboda in Ostrava since the last research carried by Koutecký (2004) and the proposal of framework of care for similar locations. For this purpose has been made 39 phytocenological relevés where were found 177 species of vascular plants. The loss of available light and heat and increase of humidity, accesible nutrients in soil, and pH, which was attributed primarily to ongoing succession, has been detected through analysis of data files. For the purposes of recovery of similar sites have been proposed the maximum possible usage of spontaneous succession.

Possibilities of biological recultivation in Okrouhlá Radouň
 VONDRÁČKOVÁ, Michaela
The aim of this text is to illustrate the ways of biological rekultivation in Okrouhlá Radouň. There is a waste bank as a residue after the uranium industry. Waste banks are common in most of mining areas. In most cases is a postmining land use as a forest. In our case maybe the forest isn´t so appropriate because of the cumulative dominance of waste bank. Because of this reason is select a reclamative rotation of crops. Another period of rekultivation is a growing of energy crops or grass cover etc. It is important to make two parts of waste bank- flopping zone and the rest of waste bank. On each of this parts is applies different ways of rekultivation. Flopping zone is solved more carefully because of the dangerous of the tree-roots which can damage the modified waste bank.
