Performance of late succession tree species in reclaimed and unreclaimed post mining heaps
Šimáňová, Doubravka ; Frouz, Jan (advisor) ; Mudrák, Ondřej (referee)
As a result of surface mining, ecosystems are destroyed, soil deposited on landfills is subject to degradation, contamination and erosion events, the water regime of the area is changed and all vegetation is removed from the surface. The most common way of rehabilitating a destroyed ecosystem is forest restoration. This can be done either by technical reclamation, during which the surface is leveled, and selected trees are planted here, or it is possible to leave the area to natural development, which is called spontaneous succession. The thesis summarizes knowledge about both methods of restoration, including their advantages and disadvantages. In the practical part, the growth production of late successional species, Norway spruce (Picea abies) and European beech (Fagus sylvatica), growing on areas left for spontaneous development and on artificially reclaimed areas, on spoil heap near Sokolov, are compared. The results show that the trees in the stand of natural regeneration have better conditions for growth, but not all measured parameters are statistically supported. Therefore, this work can serve as a survey of potentially suitable parameters for the creation of a larger-scale study. Key words: spoil heaps, forest restoration, succession, technical reclamation
