“…Bliss and Fischer (2011) have noted that successful ecological restoration requires sound ecological science, but also an understanding of the dynamic interactions among people, as well as between people and the landscapes they inhabit. Integration of social sciences with ecological research in the context of river restoration is clearly needed to increase the understanding of the overall benefits within the larger social-ecological context, as well as the efficacy and sustainability of future restoration projects (Mutz et al 2013, Naiman 2013, Wortley et al 2013. Detailed biological surveys have been conducted in our study rivers both before and after the restoration that together with this sociological data will enable the multidisciplinary evaluation of stream restoration success in our future studies.…”

ABSTRACT. Stream restoration often aims to enhance fisheries by improving stream conditions for target fish species. However, river restoration has a potential impact on a variety of ecosystem services. Among stakeholders, the emerging expectations about restoration attain different priorities. How well these expectations are met influences social perceptions of success or failure. Although public support for restoration is known to have a significant impact on the sustainability and overall success of restoration, social aspects are rarely considered in this context. To address these issues, we conducted a questionnaire study among the residents and fishermen of three recently restored rivers in Finland. Results indicate that both user groups highly supported the restoration goals, but they were not always satisfied with the restoration outcomes. The changes in landscape value and amenity and fish provisioning had the highest influence on the user groups' attitudes. Restoration-induced changes in ecosystem services showed clear variation between the different locations, but the differences in the perceptions of the two user groups were less evident. Comparing perceptions between the user groups and locations and applying the ecosystem services approach are a novel contribution to the debate on restoration success. Our study highlights the importance of perspective, social-ecological context, and adequate communication for success.

“…, 2019. The BMWP index was originally developed to represent water quality, but subsequent studies showed that it reflects ecological quality of the waterbodies and can also be related to hydromorphological impoverishment such as incision or straightening (Mutz et al, 2013;Wyżga et al, 2013;Mikuś et al, 2021). This index best considers the sensitivity of invertebrates to environmental variables because families with similar stress tolerances are grouped together (Armitage et al, 1983).…”

Abstract. Flow variability determines the conditions of river ecosystems and river ecological functioning. The variability of ecological processes in river ecosystems gradually decreases due to river channelization and incision. Prediction of the environmental flow allows us to keep biological diversity and river health developed as a response to the degradation of aquatic ecosystems overexploited by humans. The goal of the study was to test the influence of river incision on environmental flow estimation based on the Biological Monitoring Working Party (BMWP) macroinvertebrate index. A total of 240 macroinvertebrate assemblages of 12 waterbodies differing in bed substrate and amplitude of discharge were surveyed in southern Poland. Variations in the distribution of 151 466 macroinvertebrates belonging to 92 families were analysed. The similarity of benthic macroinvertebrates reflects the typological division of the rivers into three classes: Tatra mountain streams, mountain flysch rivers, and upland carbonate and silicate rivers. As a response variable reflecting the macroinvertebrate distribution in the river, the BMWP_PL index was chosen. The river incision significantly increased the values of e-flow calculations in relation to redeposited channels. The area of optimal habitat for macroinvertebrates decreased with the bed incision intensity. In highly incised rivers, the environmental flow values are close to the mean annual flow, suggesting that a high volume of water is needed to obtain good macroinvertebrate conditions. As a consequence, river downcutting processes and impoverishment of optimal habitats will proceed.
