In the present paper, the ruderal vegetation of a small town is characterized. Based on phytosociological studies, 43 associations and 5 communities were distinguished in eight functional and spatial complexes. For most of them, the diagnostic communities were identified and compared with the literature. The aim of this study was to analyze the relationship between the type of ruderal community and spatial structure of the town, and to determine whether there are any differences in the ecological requirements of ruderal species found in those complexes based on selected Ellenberg indicator values. The aim of this study was to analyze the relationship between the type of ruderal community and spatial structure of the town, and to determine whether there are any differences in the ecological requirements of ruderal species found in those complexes based on selected Ellenberg indicator values. Differences in median values for different complexes were evaluated using the Kruskal-Wallis test.
Hacquetia epipactis (Scop.) DC. of the family Apiaceae is one of the most peculiar species in the Polish flora. Outside of Pogórze Cieszyńskie and Ślądk Opolski, it is found at a few isolated sites in southern Poland. It has been protected since 2004 as a rare species. It is listed as vulnerable in the Polish Red Book of Vascular Plants. This paper presents a comparison of two insular populations of H. epipactis in Pogórze Wielickie.
The article presents plant communities of the projected nature reserve Matunin, which covers a fragment of a flood terrace of the River Odra valley and includes the Matunin oxbow lake (situated near Jelcz) and its surroundings: alluvial meadows, fields and patches of riverine shrubs and forests. Many interesting and rare plant communities, bound to oxbow lakes and riverine floodedareas, such as Trapetum natantis, Lemno minoris-Salvinietum natantis, Nupharo-Nymphaeetum albae, Rhamno-Cornetum sanguinei and Ficario-Ulmetum minoris have been found here.
