Abstract
The purpose of this study is to identify the causes of degradation and the main stress factors of urban impact on the wetlands of the Sovky tract in the city Kyiv and to justify the need of creating a protected area there. In order to achieve the goal, we investigated the geoecological state of the tract for ten years, analysed 100 water samples from Sovski ponds, identified the main sources of contamination of reservoirs and adjacent territory and proposed the urgent measures to restore and preserve valuable urban wetlands. During the research, we revealed a steady trend of increasing concentrations of nitrites (NO2-N), nitrates (NO3-N) and phosphates (PO4) in Sovski ponds. It was established that the main sources of contamination of reservoirs by biogenic substances are the untreated storm sewer drains and motor-car washings located along nearly the entire perimeter of the Sovky tract. During the studied period, the stress factors of the urban impact on wetland ecosystems were strengthening systematically, that stipulated the increase of chemical and noise contamination, clogging with household and construction waste, disturbance of the soil cover and destruction of natural habitats of plants and animals. In order to stop the degradation and to preserve the unique urban wetlands, we have offered to include them in the complement of the Nature Reserve Fund of Kyiv, in particular, to create a Regional Landscape Park within the studied territory. We drew up a functional zoning scheme of the proposed protected area in the Sovky tract based on the geoecological monitoring results, that will provide its protection from the potential building, clogging and further degradation.
