Фітосозологічне значення об’єктів смарагдової мережі дніпровського екологічного коридору в межах лісостепу України

Abstract

The Emerald Network of Ukraine provides the preservation of the most valuable and typical components of landscape and biotic diversity, including the habitats of rare and endangered species of plants. In order to ensure the effective protection of biodiversity, within the boundaries of natural or anthropogenically modified territories, the necessary condition for their flora diversity should be its study. One of the territories that is the central link in the structure of the ecological network of Ukraine is the Dnipro Ecological Corridor. Within the Dnipro ecological corridor of the forest–steppe of Ukraine are located 11 objects of the Emerald network, which is 4% of their total number in Ukraine, which are characterized by specific biotope–ecotope characteristics and which consist of a significant number of populations of endangered and rare plant species. As a result of the analysis the objects of the Emerald network, 33 habitats from Resolution No. 4 of the Bern Convention were identified (C1.222, C1.223, C1.224, C1.225, C1.226, C1.25, C1.32, C1.33, C1.3411, C1.3413, C1.67, C2.33, C2.34, C3.4, C3.51 (but excluding C3.5131), D5.2, E1.2, E1.9, E2.2, E3.4, E5.4, E6.2, F3.247, F9.1, G1.11, G1.21, G1.22, G1.3, G1.7, G1.8, G1.A1, G3.4232, X35) and 69 species of vascular plants, that belong to such protective lists : Annex I of the Bern Convention – 12, Resolution No. 6 of the Emerald Network – 11, the Red Book of Ukraine – 56 and the European Red List – 8 species. In Emerald objects, they are distributed in this way: Kanivskyi Nature Reserve – 40 species and 25 habitats, Holosiivskyi National Nature Park – 29 and 23, Nyzhnovorsklianskyi Regional Landscape Park – 26 and 21, Nyzhniosulskyi National Nature Park – 27 and 28, Kremenchutski Plavni Regional Landscape Park – 5 and 19, Kremenchutske Reservoir – 17 and 28, Kanivske Reservoir – 16 and 27, Dniprodzerzhynske Reservoir – 5 and 21, Ponyzia Stuhny – 8 and 10, Cherkaskyi Bir – 17 and 17, Mykhailivskyi – 10 and 22, respectively. Preservation and reproduction of rare species is one of the main tasks of creation the protected areas and ecological networks. An overview of the specific features of these objects and the existing conditions for conservation of biodiversity in general suggests that the considered areas, despite their very significant anthropogenic transformation, can be considered as important aspect of preservation and reproduction of rare vegetation diversity in the scale of the plains of Ukraine.
