FOREST VEGETATION IN THE MODERN NATURE RESERVE NETWORK OF THE SNOV RIVER BASIN (WITHIN UKRAINE)

The article provides a brief description of forest vegetation in the modern structure of the nature reserve fund of the Snov River basin. The network of nature reserves in the study region includes 90 forest objects of various statuses and categories with a total area of 13,330.7 ha within the Chernihiv, Koriukivka and Novhorod-Siverskyi districts. The first two objects of the nature reserve fund of the study area were created in 1958, and the vast majority in the period from 1975 to 2000. The largest category of the nature reserve fund in terms of number and area are reserves – 63 (two of which have state protection status) with an area of 10,250.9 ha; The second position is occupied by protected tracts – 11 sites with a total area of 5890.1 hectares and natural monuments – 11 (two of which have national protection status) with an area of 138.7 hectares. The largest number of protected forest areas of the Snov River basin is located in the Koriukivka district (49 objects, with a total area of 1935.5 ha, the percentage of reserves within the district is 0.79%), the middle position is occupied by the Chernihiv district (23 objects, 7147.5 ha, 3%), the last is the Novhorod-Siverskyi district (18 objects, 4247.7 ha, 2.47%). The distribution of forest vegetation within protected areas is determined mainly by edaphic and hydrological factors, which are significant in the formation of forest vegetation of the Snov River basin, its floristic and coenotic composition. The forest cover of the research area, which has a protected status in terms of coenotic composition, is mainly pine, oak-pine and alder forests with a different floristic set, and areas with spruce are found fragmentarily. The sustainability, functionality and value of the forest areas of the basin are determined by the species composition, rare components, cenotic diversity, and role in the formation of landscape complexes of the relevant territories, and form an integral part of the Chernihiv region nature reserve fund, within which an appropriate regime of preservation, protection, restoration and use is established.
