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.

Tytuł:: Monitoring małych rzek wyżynnych na przykładzie potoku Łękawka (gmina Bestwina, województwo śląskie)

Opis:: The paper presents the assessment of the water condition of the Łękawka stream according Water Framework Directive, carried out on the basis of research on benthic macroinvertebrates and the analysis of data on other indicators used in the monitoring of waters. Sampling of macroinvertebrates, taxonomic identification and calculation of the MMI_PL index were carried out in accordance with the Multi-Habitat Sampling (MHS) method according to the EU standard EN16150:2012, used in Poland for the monitoring of surface waters. Field studies were carried out in September 2022. From each site, 20 quantitative samples were taken from various fractions of the substrate present in the bottom, using a Surber net. Data on other biological indicators, physicochemical and hydrobiological parameters and chemical status were obtained from the resources of the State Environmental Monitoring, concerning the results of monitoring of rivers and dam reservoirs in Poland in 2016-2021. Studies of the invertebrate macrofauna of the Łękawka stream showed the occurrence of only nine families, dominated by taxa with a wide range of ecological tolerance. The final assessment of the ecological status of the Łękawka water body, according to the RDW guidelines, based on the results of monitoring studies, showed a bad ecological status (class V) of the ecosystem. The key in-fluence on this assessment, in accordance with the principle "the worst decides" was the value of the Polish Multimetric Ecological Quality Index MMI_PL, confirmed by the results of the hydromorphological index (HIR). The chemical status of the examined water body, determined on the basis of the results of monitoring priority substances in the field of water policy (a group of 45 indicators) and other pollutants (eight indicators), showed a "below good" class. Finally, on the basis of a comparison of the ecological and chemical status, the bad condition of the Łękawka stream was confirmed. The obtained results indicate a significant disruption in the functioning of the water ecosystem as well as a violation of the hydrological regime and morphological conditions of the streambed. It means that the achievement of the environmental goal set by the Water Framework Directive is very seriously threatened. Therefore, it is necessary to urgently regulate activities in the field of water and sewage management in the catchment area, regarding water intake and discharge of municipal and industrial sewage.
