Ecological and coenotic features of the Syrovatka river basin in the Emerald network of the Sumy region, Ukraine

A number of studies were undertaken in the territory of the “Syrovatka river basin of the Emerald Network of Ukraine (UA0000428 Syrovatka river basin). Based on the data gathered from field work surveys of the area, the characteristics of the habitats (C1.222, C1.224, C1.32, C1.33, C2.33+, С2.34, C3.4, C3.51, D5.2, E1.2, E2.2, E3.4, E5.4, F3.247, F9.1+G1.11, G1.21+G1.41, G1.A1, G1.7, G1.8, G1.A4) are presented according to the area covered and their ecological features. Phytosociological characteristics of habitats were given. As a result of the analysis of the distribution of certain species of sozophytes, a brief description of the status of the identified populations was presented. Populations of vascular plant species protected in Europe (Ostericum palustre, Iris hungarica), Ukraine (Epipactis helleborine, Lilium martagon, Platanthera bifolia), and at the regional level (Carpinus betulus, Campanula persicifolia, Calla palustris, Dryopteris cristata, Inula helenium, Utricularia vulgaris) have been studied in detail. The main threats to the existence of the natural complex of this area, which may appear in the situation of increasing economic impact are drainage and ploughing of floodplains, terracing, and afforestation of meadow-steppe slopes of the ravine. The typological characteristics of artificial and natural forest plantations of the territory were described based on the generalization of details gathered from information on their local management.
