“…A strongly cemented horizon with red ferric oxides and gypsum developed at lower depths of soil profiles (Mrázek, 2004;Kovář et al, 2011) and caused retrogradation in successional progress through periodical extinction od the tree seedlings (Kovář et Herben, 2004). Repeated restoration of initial colonization with biota includes the microhabitat dynamics at small-scale level (creation of biological soil crust) and processes of the organic matter decomposition (litter fall, dead biomass supply), bioturbation activity of the soil fauna, establishment of plant seeds and their seedlings or the insect/plant interactions, seed dispersal by zoochory and anemochory improve and use the environmental properties in the mosaic of microsites and shift the ecosystem far towards life-supporting state of spontaneous balanced succession (Kovář, 2004;Neustupa et al, 2009;Štefánek et al, 2012;Dostál et Kovář, 2013;Kovář et al, 2013). Hence, above mentioned contradictions imply irregular shifts in vegetation succession on toxic postindustrial wastes and differentiated qualitative composition of plant stands inside and outside the deposited substrate body.…”
