The association has been observed in industrial reclamation areas in the vicinity of carbonate mineral excavation sites in the central part of the Opole region. In the vast majority of cases, plots of this association developed in reclaimed areas. The majority of diagnostic species for the association was found within surveyed plots, including Verbascum thapsus, V. densiflorum and Bryum argenteum. Taxa characteristic of the alliance were also constantly present, i.e. Daucus carota, Melilotus alba, M. officinalis, Echium vulgare and Erysimum hieracifolium. This association belongs to the rarest syntaxa in Poland included in the Dauco-Melilotion alliance of ruderal communities with a predominance of hemicryptophytes, therophytes and perennials. The main diagnostic species - Crepis rhoeadifolia, belongs to very rare elements of Polish flora. It has been observed only in the southern part of the country in approx. 20 sites. Crepis rhoeadifolia had not been observed in Silesia for approx. 40 years, which is why it was considered to be an extinct taxon in this region. Rediscovering of the species allowed for diagnosing the Dauco-Crepidetum rhoeadifoliae association. This association is an example of a pioneer phytocenosis of, most likely, anthropogenic origin in Silesia.

Introduction Mineral excavations, both disused and currently exploited ones, are convenient habitats for numerous 1.1 Mineral excavations and post-mining plant species [e.g. 3,4]. Quarry flora and vegetation reclamation areas as a focal point of was researched in the United States, [5,6] showing, floristic studies among others, a range of rare and vanishing species The Silesian region is of exceptional importance (=sozophytes sensu Nowak A. [7]) at national scale. In for rock mining. This is caused by a variety of rock Germany, rare and receding species were observed in masses of differing age presenting nearly the entire quarries by Mückschel [8] and other authors. In Silesia, history of the Earth’s crust development from the research concerning mineral excavations has been Precambrian Era. In the vast majority of cases, rock conducted with moderate intensity. Such research materials are excavated by means of strip mining. was performed by Stojanowska [9], Badora et al.
