Ash and slag from CEZ Skawina Power Plant were deposited for many years onto wet landfill in Kopanka village near Skawina town, south of Poland. All of it resulted in a change of hydrological relations, increasing rewetting neighbouring arable land and meadows. In the process succession plant communities formed, which became the contents of this document. The aim was to monitor plant associations changes due to rewetting soils of described areas. Braun-Blanquet phytosociological method was used. The evaluation of vegetation found a parallel to landfill edge strips of plants associations, which decreased amount of hygrophilous plants with increasing distance from the landfill.
