The paper presents the diversity of natural and anthropogenic forest communities occurring in post-cultivated fields in Glinno Ługi. An impoverished fresh pine forest association (Leucobryo-Pinetum) and nine secondary forest communities have been distinguished in the transect line (1.16 km in length). Factors influencing the structure and species composition of recent forest communities, such as habitat properties, previous land use forms and the intensity of forest management, are described.

Contents of Zn, Cd, Ni, Mn, Cu, Pb and Fe in 36 samples of Scots pine collected in 9 sites located in the Upper Silesia Province have been determined using AAS technique. The samples were digested before the analysis. On the basis of cluster analysis the existence of links between the quantitative composition, the sampling sites and the type of the matrix have been found. The coexistence of certain groups of elements was found and described.

Oszacowano stężenia Zn, Cd, Ni, Mn, Cu, Pb, Fe, w 36 próbkach sosny zwyczajnej pobranych w 9 punktach umieszczonych na terenie województwa śląskiego. Mineralizaty były badane na zawartość wyżej wymienionych pierwiastków przy zastosowaniu AAS. Największe stężenie oznaczanych analitów stwierdzono w Jaworznie. Na podstawie analizy skupień stwierdzono istnienie powiązań pomiędzy składem ilościowym a miejscami pobrania próbek oraz typem matrycy, a także stwierdzono i opisano współwystępowanie obok siebie określonych grup pierwiastków
