Opis:
The quality of surface water in watercourses in the region of Lublin agglomeration was studied in 2012–2014. Biological and chemical indicators of the study for various sampling sites were detected and the resulting values of the indicators were processed statistically. Rivers characterized by small size and the flow and modification of the riverbed. The resulting low values of macrophyte river index and infusorial index pointed to a poor quality of surface waters. Chemical indicators of the quality of surface waters reached low values, only BOD and phosphates reached high values. The river is located outside the city and it is characterized by moderate potential ecological (III quality class), and the river within Lublin is insufficiently potential ecological (IV quality class). Statistical analysis showed high variability index values between the studied positions.

Opis:
The paper presents an assessment of the ecological potential of the Soła river based on the benthic macroinvertebrates and diatomaceous phytobenthos, according to the principles of the Water Framework Directive. The calculated values of Multimetric Diatom Index (IO) indicated class II of ecological potential, while the Multimetric Macroinvertebrate Index (MMI_PL) − class III. The final classification of biological, physicochemical and hydromorphological elements showed that the examined section of the Soła river represents a moderate ecological potential which indicates a moderate disruption in the functioning of the water ecosystem as well as a violation of the hydrological regime and morphological conditions of the riverbed.

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.
