RESTORATION OF DEGRADED URBAN WETLANDS (BY THE CASE OF SOVSKI PONDS IN KYIV)

The article is devoted to the problem of the preservation of urban wetlands as the most vulnerable valuable ecosystems in the conditions of rapid urbanization, which need to be protected. It researches the current state of the Sovky tract (and the lower cas­cade wetlands of the Sovski Ponds located within it) in the center of Kyiv. Despite the strong urban influence, the rich floristic and faunal diversity of the studied area has been revealed. The value of urban wetlands for Kyiv is determined by the vital ecosystem services provided to the local community. Such services include, first of all, regulation of the microclimate, moisture and nutrients distribution in the soil, habitats preservation for the rare species of animals and plants, regulation of the groundwater levels, pollution filtration, waste adsorption, oxygen produc­tion and carbon dioxide absorption, water quality improvement, mitigation of the climate change consequences, creation of the favourable conditions for recreation, etc. As a result of field surveys of the Sovky tract, the complete decline of the territory and the degradation of valuable wetlands have been indicated. We have investigated the main geoecological conflicts caused by littering of the territory with household and construction waste, persistent pollution of the water bodies caused by untreated sewage due to unauthorized intrusions of resi­dents into the household sewers, chemical and noise pollution from the road infrastructure, grass burning in spring, etc. The spatial localisation of all conflicts within the Sovky tract is shown on the relevant map. The negative consequences of the long-term unresolved conflicts for the functioning of the wetlands and the quality of the ecosystem services they provide have been identified. Given the perspective of development in the study area of the ecopark and a fairly general idea of the essence of this concept, we proposed to include wetlands of Sovky tract in the Nature Reserve Fund of Kyiv. According to the current legislation, this area meets all the criteria of the category “Regional Landscape Park” (RLP).The main purpose of preserving the unique urban wetlands is the protection of rare species of plants and animals and their natural habitats, which is possible only in the conditions provided for in the RLP reserved zone. In addition, granting the official status of a protected area will make it impossible to build and litter within unique urban wetlands in the future.
