BIODIVERSITY OF THE BALK SYSTEM OF TERESHKIVKA VILLAGE (SUMY DISTRICT) AS A PERSPECTIVE ENVIRONMENTAL AND RECREATIONAL TERRITORY
Abstract
The article is devoted to the study of biodiversity of the balk system of Tereshkivka village (Sumy district), in order to assess its sozological, scientific, educational, aesthetic and recreational value and give this area environmental status. The field studies of the balk system, which is located northeast of the village Tereshkivka of Sumy region and covers an area of about 140 ha, was carried out during 2019–2020 using classical geobotanical and zoological methods. Along the study area there are agricultural lands, which include the slopes of the balk, that threaten the integrity of landscapes and is the cause of soil erosion. Phytocenoces differ significantly in different parts of the balk due to differences in ecological and coenotic conditions. The southern (closed to the village) part of the balk is a system of dry meadow lands formed on the bottom and on the slopes of the balk, which are at different stages of pasture digression. These are mostly herbaceousfescue groups with dominance in some areas of Festuca ovina L. and in some areas of Agrimonia eupatoria L. A population of the regionally rare species Jurinea cyanoides (L.) Reichenb., which is also included in Annex I of the Berne Convention, was found in the area of the steep slope of the northeastern exposition balk as a part of Agrostis stolonifera plant coenosis. In the branches of the central part of the balk the presence of two territorially separated populations of the valuable medicinal plant – Chamerion angustifolium (L.) Holub. was noted. A regionally rare species of Salix rosmarinifolia L. has been found in the northern part of the balk. In the fauna list, among the invertebrates and birds, there are regional rare species, which according to the IUCN status belong to the LC categories, and among birds a significant number of species are listed in Annex II of the Berne Convention. Mammals are represented mainly by a variety of rodents. Among the reptiles there is Lacerta agilis species – the species from the Annex II of the Berne Covention and according to IUCN has the status of LC. So, the presence within the studied balk system of the species representing a rare component of biodiversity, high species richness, significant reserves of medicinal plants, as well as taking into account scientific, cognitive, environmental, educational and recreational value, we consider that balk system located near the village Tereshkivka is a perspective protected area for the creation of landscape reserve of local importance.
