Phytosociological research was carried out in the town of Kłobuck, Silesian voivodeship. During the years 1998 and 1999 35 releves were taken using Braun-Blanquet method. In the study area 14 plant herb communities were distinguished, 10 of which were classified as associations. These are: community with Lenina minor, Nupharo-Nymphaeetum albae, Sparganietum erecti, Phragmitetum australis, Typhetum latifoliae, Glycerietum maximae, Phalaridetum arundinaceae, community with Jasione mon/ana, community with Deschampsia caespitosa, community with Holcus lana/us, Filipendulo-Geranietum, Scirpetum silvatici, Epilobio-Juncetum effusi, Arrhenatheretum eleatioris.

The area and object of the floral research was the town of Kłobuck with protection zone in Silesian voivodeship. Research has been earned out during the years 1988 and I 989. In the investigated area 388 species of vascular plants were identified. The results of the analysis are expressed in the following statements: The most of species belong to Asteraceae, Poaceae and Rosaceae families, Stable inhabited antropophytes constitute I 0% of flora, Among life forms in Raunkiaer' s classification hemicryptophytes are dominated species, Strong expansive species have a large shave, In terms of habitat conditions, the most common were species with full-light and temporary shade preferences, moderately warm conditions, humid condition typical for fresh soils, trophism typical for rich soils, pH of ground from moderately acidous to weakly acidous, dispersion of the ground related to loamy soils and ground content of organic matter as in mineral-humus soils, In the research area 6 strict protected species and 8 partial protected species, I species in danger of extinction and 13 rare on the Upper Silesia area were found, 7 species of mountain plants were identified.

The field investigations concerning water and peat bog communities on the territory of Trzebinia in 2000 revealed their little diversity caused by a small number of large water bodies and performed betterment drainages. 12 syntaxa were distinguished which represent 5 classes: Lemnetea minor is (I), Potametea (6), Utricularietea intermedio-minoris (I), Littorelletea uniflorae (I), Scheuchzerio-Caricetea nigrae (I). Among described units 3 plant associations are endangered within Upper Silesia: Myriophylletum verticillati, Hottonietum palustris, Valeriano-Caricetum flavae (montane plant association).

As a result of the field survey carried out in the area of Trzebinia in years 1999-2000, 642 vascular plant species were recorded, many of them represented by: Asteraceae. Fabaceae, Cyperaceae, Rosaceae families. 51 taxa were not confirmed. Among life forms hernicryptophytes predominate. With regard to habitat conditions, there are mostly photophilous species preferring full light with temporary shading and temperate warm and temperate cool temperature conditions, fresn and humid soils with pH ranging from light acid to alkaline, rich in organic compounds. sandy-clay or heavy clay soils. In the flora of the town species of alien origin have huge contribution ( 19.8%). Archaeophytes and among kenophytes - agriophytes, are the most frequent. Despite considerable synanthropization the nora of the town is characterized by a large participation of protected species (40) and endangered ones in the scale of Upper Silesia (84). However, there are not many montane species ( 15). The most precious area in Trzebinia, from floristic point view, is Podbuczyna and the most disturbed - the centre and Chechlo.
