Diversity of spontaneous plant communities on postindustrial sites

The industry sites regardless of any reclamation are subject to natural processes (succession). It is the result of ecology in its basic meaning - the interrelationships between living organisms and their immediate habitat (industrial wasteland). The biological diversity (number of species, and number of plat assemblages and communities) reflects the microdiversity of specific habitat. Plant communities representing varied ecological and phytosociological groups were investigated during the long-term fieldwork. The multivariate conditions at the restoration sites are the obvious but unfortunately very complex factor of wasteland reclamation. The objective of the article is to present the diversity of spontaneously created plan assemblages and communities and assemblages on coal mine sedimentation pools and sand-pit open casts. All recorded plant communities and assemblages represent 13 phytosociological classes. 67 communities and assemblages recorede on sedimentation pools and analysed according to the moisture conditions, structural complexity, frequency, area covered, and dynamics status.
