A composition of snail fauna in a functional coal-ash settling basin has been compared to that of a partly reclaimed coal-ash settling basin which had been abandoned for 26 years, using a nature reserve as a control. A total of 24 molluscan species were found at the control site, 21 species in the internal area of the abandoned settling basin and six species in the internal area of the functional settling basin. Numerous and relatively diverse malacofauna have become established on the abandoned coal ash settling basin, consisting mainly of high populations of a low number of widespread species.

Occurrence of rare and protected plant species is regarded as a strong argument for creating a protected area. It is therefore especially important to know whether rare and protected species are reliable indicators of abundance of other, more common, unprotected species. We analysed co-occurrence of protected and rare species with other xerothermic plant species in calcareous xeric grassland in Western Poland. In the years 2005-2006, on 62 plots (25 m[^2] each) we identified vascular plants on a 60 km[^2] area in the Odra R. Valley and its smaller tributaries valleys. Legally protected species appeared not to be better indicators of xerothermic species richness than non-protected species. The rarest species (Anthericum liliago L., Carex supina Willd. ex Wahlenb. and Stipa borysthenica Klokov ex Prok.) were significantly less useful indicators of xerothermic species richness than other rare and common species. These results let us conclude that designing a network of protected areas on the basis of rare and protected species may result that some common species, biodiversity hotspots or well developed phytocenoses will be ignored.
Some results of investigation of zinc, cadmium. lead, manganese, iron and sulphur content in the leaves of: Picea abies (L.) Kersten., Acer pseudoplatanus L., Fagus sylvatica L., and Oxalis acetosella L., and in upper layer of the soil were presented. The amount of metals accessible for plants was analysed as well. The investigations were carried out in 2001-2002. In the soil of both nature reserves situated in the city Katowice the zinc concentration was high (300 žg/g). The "permitted" and considered as non-toxic level of lead (110 žg/g) and Cd (10 žg/g) was exceeded. The level of investigated metals in plants was high. Successively cadmium, lead and zinc: 10 žg/g d.w., 150 žg/g d.w, and 300 žg/g d.w.

In 13 forest reserves situated in southern Poland, 68 study plots were established in two regions: the Jurrasic Upland and the Silesian Upland. In these plots, size 10 m x 10 m divided into 100 subplots 1m2 each and randomly placed in various forest communities, percentage cover of all species in ground layer was recorded. Relationships between highly invasive alien plant species, Asiatic small balsam Impatiens parviflora DC, and indigenous species, was estimated using various indexes of species richness and diversity. They were: Hill's numbers (N[0], N[1], N[2]), Shannon-Wiener's index at the level of a subplot, alpha diversity (species richness within sites), and beta diversity (species richness among sites) at level of a study plot. The subplots with a presence of I. parviflora were compared with those where only native resident species occurred. The study has shown that subplots with the occurrence of I. parviflora are characterized by higher species richness and diversity of native plants independently on vegetation type. The frequency of I, parviflora was negatively correlated with beta diversity of study plots but there was no association with values of alpha diversity. In oak forest, alder carrs and floodplain forests the negative correlation between percent cover of I. parviflora and species richness, as well as cover of the herb layer was observed. The percent cover of /. parviflora was positively correlated with number of native species in beech forest and with their total cover in mixed coniferous forests. However, in natural well-preserved forest phytocoenoses I. parviflora avoids patches characterized by high cover of ground layer species and colonizes empty sites as an additional element of a community.
Results of supplementary hydrogeochemical analyses, conducted in the Kampinos National Park (KPN), its buffer zone and in the reserve “Bielany Forest” (“Las Bielański”) allowed revising the location of monitoring points and proposing a basic set of analyses of quality, ground-water level. This set includes measurements of physical-chemical parameters enabling to assess water quality and to define causes and consequences of groundwater chemical composition changes. Analyses of the water level monitoring results and selected hydrogeochemical indicators allows for assessment at antopopressure intensity. The survey results led to suggesting necessary range of physical-chemical tests and frequency of monitoring in affected areas under different antropopressure level.
The article describes the vegetation growing on settlings and washing tanks situated in the "Żabie Doły" area (Bytom). There were recognised 2 plant associations and 6 plant communities which belong to Artemisietea, Molinio-Arrhenatheretea, Calluno-Ulicetea classes. Among them dominate communities from Dauco-Melilotenion suballiance which are confined to dry, permeable soils with the initial soil-forming process (Meliloletum albo-officinalis, Dauco-Picridetum hieracioidis, Calamagrostis epigejos community, Solidago canadensis community). There were recorded also swards (Fesluca ovina community) and meadows (Deschampsia caespitosa community, Agrostis capillaris community).

Badania prowadzono na obszarze "Żabich Dołów" (Bytom) na powierzchni osadników flotacyjnych i popłuczkowych powstałych w wyniku eksploatacji i przerobu rud cynku i ołowiu. Analiza zebranego materiału pozwoliła na wyodrębnienie 8 syntaksonów, w tym 2 zespołów i 6 zbiorowisk roślinnych z klas Artemisietea, Calłuno-Ulicetea, Molinio-Arrhenatheretea. Wśród wyróżnionych syntaksonów dominują zbiorowiska roślinne należące do podzwiązku Dauco-Melilotenion, rozwijające się w miejscach przesuszonych, na podłożu piaszczystym, przepuszczalnym, często o słabo zaznaczonym procesie glebotwórczym (Melilotetum albo-officinalis, Dauco-Picridetum hieracioidis, zbiorowisko z Calamagrostis epigejos (L.) Roth; zbiorowisko z Solidago canadensis L.). Na badanych obiektach odnotowano również fitocenozy murawowe (zbiorowisko Z Festuca ovina L s. str.) i łąkowe (zbiorowisko z Deschampsia caespilosa (L.) P. Beauv., zbiorowisko z Agroslis capillaris L.).
W latach 1999-2002 przeprowadzona badania briologiczne na terenie rezerwatu przyrody "Kuźnic" położonego w Beskidzie Śląskim koło miejscowości Twardorzeczka (gmina Lipowa, powiat żywiecki). Rezerwat znajduje na wysokości 800-1010 m n.p.m. i zajmuje powierzchnię 7,22 ha. Największą powierzchnię porasta dolnoreglowy bór jodłowo-świerkowy Abieti-Piceetum. Analiza częstości występowania wykazała, że najliczniejszą grupę stanowią mchy bardzo rzadkie (40,7%). Do najważniejszych składników muskofiory należą: jeden gatunek objęty ochroną częściową oraz wiele taksonów rzadkich w Beskidzie Śląskim, np. Anomodon mgelii, Cirriphyllum tommasinii, Neckera crispa, Orthotrichum stramineum i Racomitriwn aquaticum. Szczegółowo scharakteryzowano 5 głównych grup ekologicznych mchów.

In the years 1999-2002 bryological investigations were carried out within the "Kuźnic" nature reserve located in the Beskid Śląski Mts. near the village Twardorzeczka (Lipowa commune, Żywice district). The "Kuźnic" nature reserve lies between 800 and 1010 m above sea level and covers 7.22 ha. In its area coniferous forest Abieti-Piceetum predominates. In the result of this research 59 taxa have been noted. The analysis of frequency range showed that overwhelming majority of the moss flora consists of very rare taxa (40.7%). The most important components of the moss flora arc: one partially protected species in Poland and many species which are rare in the Beskid Śląski Mts., for example Anomodon rugelii, Cirriphylhttn tommasinii, Neckera crispa, Ortholrichum stramineum and Racomitriwn aquaticum. Five main ecological groups of mosses were characterized in detail.
W latach 1999-2002 przeprowadzono badania briologiczne na terenie rezerwatów przyrody "Mokrzyk" (gm. Jasienica, pow. bielski) i "Skarpa Wiślicka" (gm. Skoczów, pow. cieszyński) położonych w zachodniej części Pogórza Śląskiego. Ich powierzchnia wynosi 11,47 ha ("Morzyk") i 24,17 ha ("Skarpa Wiślicka"). W omawianych obiektach dominują naturalne zespoły lasów liściastych (głównie Dentario glandulosae-Fagetumt, Tilio-Carpinetum i Carici remota-Fraxinetum). Brioflora rezerwatów liczy ogółem 11 gatunków wątrobowców i 69 gatunków mchów, z czego w rezerwacie "Morzyk" stwierdzono 7 gatunków wątrobowców i 51 gatunków mchów, natomiast w rezerwacie "Skarpa Wiślicka" - 9 gatunków wątrobowców i 57 gatunków mchów. Analiza częstości występowania wykazała, że najliczniejszą grupę stanowią mszaki bardzo rzadkie ("Morzyk" - 50%; "Skarpa Wiślicka" - 50%). Do najcenniejszych elementów brioflory należą mszaki nowe oraz rzadkie na Pogórzu Śląskim, takie jak: Brachythecium campestre, Bryum klinggraeffii, Fissidens exilis, F gracillifólius, Hommtallium incurvaum, Orthodicranum tauricum, Riccia rhenana i Taxiphyllum wissgrillii. Wyróżniono i scharakteryzowano 6 głównych grup ekologicznych mszaków.
