Reclamation of the derelict land is very actually problem in reconstructed region - agglomeration of Katowice. This places are colonised, in a spontaneous succession process of the vegetation by some plant species. Investigation of this process are continued in spoil heaps in Upper Silesia region (CABAŁA AND SYPIEŃ, 1987; PATRZAŁEK AND ROSTAŃSKI, 1992; ROSTAŃSKI, 1997a; ROSTAŃSKI 1997b), in other post-industrial sites of Poland (BALCERKIEWICZ AND PAWLAK, 1990) or Europe (JOCHIMSEN ET AL., 1995). The aim of this paper is to present up-to-date floristic list of grasses, which spontaneously exist in post-industrial sites in Upper Silesian region and the short analysis of this list. The flora of grasses consists of 57 spontaneously occurring species. Native species contributed 70% of the total species number. Among alien species (30%) the important groups are archaeophytes (15%) and kenophytes (10%). In total flora the perennial (hemicryptophytes, geophytes), heliophilous, mesophilous and expansive grass species are dominated.
