The subject of this study was the effect of surrounding vegetation on the species composition of the dumps after black coal mining. The species data from dumps and their surroundings up to 100m were recorded during the vegetation seasons 2009-2011 and consequently analysed using ordination methods (DCA and CCA) and univariate statistics. The data on land cover and percent of the old forests (present in the surroundings in years 1836 -1852 up to 100m and 1km from the margins of the dumps) appeared to have significant effect on the present species composition of vegetation on the dumps.
