Abstrakt: The aim of our study was to determine whether the values of plant community diversity, the volume of wood, and the partial economic efficiency of plots left to spontaneous succession have yet reached similar values as those recorded on forestry reclaimed plots. Six forestry reclaimed plots and six plots with spontaneous succession were established at the Great Podkrušnohorská spoil heap and selected tree biometric characteristics were measured. Plots’ economic efficiency was calculated as the difference between the costs to level the spoil heap as well as establish and manage the forest reclamation and the theoretical profit from wood. The numbers of tree species, numbers of individuals, wood volume, and Simpson diversity index values did not differ significantly between plots with spontaneous succession and reclaimed plots. The economic efficiencies of both types of plots were too burdened with high initial investments for levelling, which can theoretically be returned within 300 years for reclamation plots and 180 years for succession plots. According to our results and those of some other authors, values for diversity and wood production are similar or higher on plots resulting from spontaneous succession in comparison to values on reclaimed plots. For this reason, both types of management should be used to establish a new suitable mosaic of ecosystems in the post-mining landscape.
