Abstract

The economic use of rivers in many cases has led to the degradation of their beds, the interruption of ecological continuity, and its defragmentation. In Poland, the effect of restoration activities in the mountain river bed has rarely been analysed. The article presents an analysis of hydraulic conditions and habitat structure, as well as a hydromorphological assessment of the river in selected sections of the Wisłoka River after completion of activities improving fish habitats. On a section of the Wisłoka River, about 30 km long (from the weir in Mokrzec to Pustków), ten sections were selected, which were subjected to restoration activities. These activities included spatial differentiation of water flow conditions in the channel to improve the habitat conditions that were obtained by (i) laying boulder clusters, (ii) depositing a bedload in the river bed, and (iii) forcing a change of the horizontal river system through controlled lateral erosion of the banks. As part of the restoration activities, the diversity of habitat types on the sections examined has significantly increased, which, in the future, should lead to an increase in the diversity of benthic fauna and macro-invertebrates.
