Results of the assessment of small water retention reservoirs and wastewater treatment constructed wetlands ecosystem services in rural landscape

Popis výsledku v původním jazyce

Small water reservoirs (SWRs) are one of the principal elements of the agricultural landscape in the Central European context with different functions including water retention, flood protection, fish farming, biodiversity conservation, water treatment angling and other recreational activities. Since 1990, different types of constructed wetlands (CWs) have been used as a tool for wastewater and polluted water treatment in rural areas of the region. The contribution aims to present a set of case studies of specific implemented reservoirs and wetlands, their long-term contribution to the improvement of the landscape state, the diversity of biotopes, the water balance and the efficiency of removing water pollution. Specific data from the analysis can help determine or estimate the ecosystem services of the observed types of reservoirs and wetlands.In general, it can be stated that properly designed and built SWRs and CWs can retain nutrients with high efficiency, both in the water phase and in the erosion wash. The combination of mechanical pretreatment and horizontal and vertical flow wetlands achieves the highest efficiency of capturing and removing nutrients and other pollution from wastewater and diffuse sources in agricultural landscapes. Designing the retention space as an artificial wetland with a low water level, or without a permanent water surface, also shows high efficiency for water purification in the case of retention SWRs, while maintaining the anti-flood function.Practically all properly designed and implemented SWRs and CWs have been able to perform the required services in the long term. The exceptions were locations with incorrect design (e.g. dimensioning of objects) and/or incorrect operation (regulation of invasive species, incorrect composition of fish stock, maintenance of vegetation, etc.).
