Opis:: The paper presents preliminary results of the studies concerning influence of geotextiles stabilizing the soil on vegetation of post-excavation slopes and drainage ditches. Analyzed anthropogenic habitats are situated in Międzyrzecze and Nieboczowy (Silesian Province, Southhern Poland). They have been previously subjected to reclamation treatment, consisting in installation of wool and synthetic geotextiles in the ground. The studies on plant community were conducted according to commonly applied Braun-Blanquet approach. Recorded phytocenosis were classified into Molinio-Arrhenatheretea R. Tx.1937 and Stellarietea mediae R. Tx., Lohm. et Prsg.1950 class. For comparison of plant patches growing on two variants of geotextiles Hierarchical Cluster Analysis was used. Moreover, the number of species (S), Shannon-Wiener index (H), evenness index (J) and average heights of herbal layer were calculated. It has been shown, that the type of geotextiles has a slight influence on the variability of investigated plant patches. However, relatively high differences in total coverage and mean height of herbal layer between plots protected and unprotected were observed. It shows that the geotextiles support the process of natural ecological succession on habitats with high inclination, mainly through water retention and reduction of erosion.

Opis:: Parks are undoubtedly areas of great natural value to the city, mainly due to the ecosystem services and ecological functions they provide. An important component of every park is its forest stand. In this paper, the study of dendroflora were conducted in seven parks of Bielsko-Biała. The parks were created in the 19th century. They are located mainly in the central part of the city. This paper presents the results of the study on the species composition as well as the quantity of each species in the parks. Furthermore, basic dendrometric characters such as tree height and circumference at the breast height were also analyzed. A total of 615 trees belonging to 32 species from 21 genus and 12 families were found in parks. There was a dominance of deciduous trees (28 species) over conifers (5). The largest number of examined trees was in Strzegowski Park, and the smallest in Park at Komorowicka Street. In turn, the largest number of species was in Słowacki Park, and the smallest in the Park near to Zipser villa. In addition, the presence of 144 specimens with monumental dimensions was indicated. Most of the park trees had dimensions in the range of 200–300 cm in terms of circumference at the breast height and height in the interval 20–30 m. Typical trees that occur in the natural forest communities of Poland were noted in the parks. These include: oaks, beeches, ash trees, hornbeams, alders, maples or lindens. Some of them are often selected for planting in parks and avenues. Of the 32 tree species, 10 were most numerous: Tilia cordata, T. platyphyllos, Acer platanoides, A. pseudoplatanus, A. saccharinum, Fraxinus excelsior, Alnus glutinosa, Carpinus betulus, Aesculus hippocastanum and Quercus robur. Among examined species, alien invasive species (Robinia pseudoacacia and Quercus rubra) were noted. They are classified as medium invasive plants. In this paper the authors pointed out the parameters that can affect the number of trees included in the study, for example: minimum circumference at the breast height, park area, age of the forest stand and local condition. Therefore, further research regarding the dendroflora in parks of Bielsko-Biała should be expanded with additional analyses, especially to determinate full species composition and changes in the stand.
