Polish Botanical Journal 56(2): 245–260, 2011 GRASSLANDS OF A Zn-Pb POST-MINING AREA (OLKUSZ ORE-BEARING REGION, S POLAND) GRAŻYNA SZAREK-ŁUKASZEWSKA & KRYSTYNA GRODZIŃSKA Abstract. We studied the diversity of grasslands in the Olkusz Ore-bearing Region (OOR). The OOR area has been severely degraded by Zn-Pb mining and polluted with heavy metals originating from mine and industrial waste and from industrial emissions. We assessed the species composition and cover of vascular plants, mosses and lichens in 9 plots at each of 28 study sites on two types of substrate (sands and dolomite mining waste). In the 252 study plots we recorded 260 species. Only one species was common (Festuca ovina) and four were noted frequently (Rumex thyrsifl orus, Leontodon hispidus subsp. hastilis, Ceratodon purpureus, Bryum pallescens). Most numerous were species typical of calcareous, warm, dry habitats and mesophilous meadows; species characteristic of poor sandy habitats and fi elds were rarer. Metallophytes were also fairly often noted (e.g., Cardaminopsis halleri, Biscutella laevigata, Brachythecium albicans, Diploschistes muscorum). Grassland diversity depended on substrate type and land use history. Grassland of abandoned fi elds developed on fertile sandy soil was richest in species, with numerous meadow and weed species (Crepis biennis, Melandrium album). Grassland on poor sandy soil was poor in vascular plants but rich in lichens (Cladonia rei, C. monomorpha). Grassland on mining ore-bearing waste was rich in thermophilous and meadow species (Thymus pulegioides, Lotus corniculatus). Grassland on mining waste was fl oristically similar to the Armerietum halleri association of metalliferous areas of Western and Central Europe. It differed by the presence of Biscutella laevigata and the frequent occurrence of Rumex thyrsifl orus, Cardaminopsis arenosa, Gypsophila fastigiata, Potentilla arenaria and Anthyllis vulneraria. The OOR grasslands, especially those developed on mining waste, should be placed under legal protection, as they contain species that are rare and unique for Poland. These grasslands increase the biotic diversity of this post-mining region and form colorful islands on its landscape. Key words: mining waste, sands, heavy metals, vascular plants, bryophytes, lichens, phytosociology Grażyna Szarek-Łukaszewska & Krystyna Grodzińska, Department of Ecology, W.

DCA biplot of plots and species against fi rst two axes of variation. Each symbol represents one plot; different symbols indicate the seven groups of grasslands (A–G) distinguished in Table 3. Species abbreviations given in Table 3. offi cinalis and the moss Amblystegium serpens. It they differed in species richness and the shares was somewhat related to groups D, F and G on of taxonomic groups. We recorded 37 species in mining waste by the presence of Leontodon group B and 14 in C, but more than 100 in each hispidus and Achillea millefolium, and to group of groups D to G (Table 2). Lichens played the B on poor sandy soil by Rumex thyrsifl orus and main role in groups B and C, comprising ca 70% Ceratodon purpureus. of all species; vascular plants formed more than Groups B to G were linked by the presence 50% of all species in group D; vascular plants of species typical for thermophilous grassland and lichens each accounted for ca 40% in groups (Festuca ovina, Cardaminopsis arenosa, Vez- E and F; and ca 70% of all species were vascular daea leprosa, Cladonia pyxidata) (Table 3), but plants in group G.
