Our research proves necessity to establish the national landscape preserve “Streshinsky” in the Dnipro flood-lands at the stretch Zhlobin-Rechitsa. This territory is a component of a migration corridor of European significance. The Dnipro left bank floodplains that have been preserved in their original state, represent a unique natural landscape. The Dnipro River serves as a natural migration channel along which certain species travel far distances to the south or to the north of the main area borders. Therefore the flora in this area is a unique complex of species of various origins: of the northern, of the moderate climatic zone, and the southern (forest-steppe and steppe). Over 600 species of highest vascular plants (tracheophytes) were identified in the preserve flora, including 8 rare and protected species. Meadow flora dominates over other types of vegetation, being represented by almost all species present in Belarus, including 11 rare and valuable ones. Alongside meadow flora, 14 categories of highly valuable plant communities were identified in the territory under analysis. Among these are flood-land oak groves, ash and hornbeam forests, open up-river and down-river sedge marshes, bayou lakes and shallow parts with rare protected species. Considerable area of the flood-lands and mosaic landscape create favorable habitat conditions for a variety of animals and birds. Numerous predatory birds, all species of river duck registered in Belarus and 12 species of sandpipers (that sometimes form large colonies) are to be found in this territory. In the course of fieldwork, the fauna of land vertebrates in the preserve area was observed to consist of 46 mammal species, 163 bird species, 5 reptile species, 10 species of amphibia and 42 fish species. Among the above are 38 animal species cited in the Red Book of Belarus, including 4 mammal, 31 bird and 3 fish species. The territory of the future preserve is of an international significance with regard to the preservation of populations of a number of rare and extinct species of European fauna. The greatest value of this territory is that it has become a permanent habitat for considerable populations of globally threatened bird species and some species of a similar status, in particular: Aquilla clanga, Crex crex and Gallinago media (Ramsar Criterion 2). The preserve territory is of great importance for migrating waterfowl: Philomachus pugnax, Anser albifrons, Anser fabalis and Anas Penelope (Ramsar Criterion 5). The preserve territory supports the populations of such species as Anas strepera, Anas clypeata and Haematopus ostralegus that have a national significance. As the future landscape preserve is to be located in the vicinity of a large industrial center and in the zone of an active economic development under the immediate impact of trans-European transportation corridor, the environmental background will be unfavorable for a sustainable functioning of natural ecosystems, unless they are given a special protection status. Unusual biodiversity of the territory, its location in the Dnipro flood-lands and its important role in sustaining populations of a number of globally protected species are all factors necessitating the establishment of a landscape preserve in this territory, which will be a crucial step towards the formation of an environmental corridor within the Pan-European environmental network. Within the frameworks of this project the establishment of the national landscape preserve “Streshinsky» in the flood-lands of the Dnipro River at the stretch Zhlobin-Rechitsa was substantiated from environmental perspective. All required documentation was prepared (including the map of land under the preserve (scale 1:50,000), draft Regulations on Landscape Preserve, boundary specifications, etc). The plans to establish the preserve were tentatively coordinated with the relevant local self-government bodies. Based on the research findings, a petition was submitted to the Ministry of Natural Resources and Environmental Protection for including the landscape preserve “Streshinsky” into the Chart of Sustainable Distribution of Specially Protected Territories of the Republic of Belarus, and another petition for additional funding to complete its establishment.
