Materials to the creation of the botanical preserve of local importance "Novozhanivskyi" (Kharkiv City, Ukraine)
Abstract
The results of ecological and floristic studies of the rarity component of the urban flora of Kharkiv City in the valley of the Udy River within the Novobovarskyi microdistrict are presented. Field studies were conducted in 2017‒2020. A triangular section of 30.48 hectares was investigated near the Novozhanovo railway station. It is located on the left bank of the river Udy and is bounded on both sides by railway embankments. The Udy River valley is situated in the northeast of the city, mainly in the previously underdeveloped areas; its significant part lays in the exclusion zone of the Kharkiv railway junction and road transport routes. A large area of the river valley is swampy, therefore unsuitable for economic use. The Udianskyi eco-corridor of local importance passes through the city. It consists of two key areas: the Zhovtnevyi Hydropark wetlands and the Kriukivskyi hydrological reserve of local importance. Currently, it has been proposed to create a botanical preserve of local importance "Novozhanivskyi" for the protection of species and associations rare for Kharkiv Region and for conservation of the true meadow formation (Prata genuine) of the class Festuceta pratensis. The site is of scientific importance, since a number of species growing there are listed in the Red Data Book of Ukraine and need protection under Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) – Ophioglossum vulgatum, Botrychium lunaria, Anacamptis coriophora, A. palustris, Epipactis palustris, Parnassia palustris, Centaurium erythraea, C. pulchellum, Valeriana officinalis, Inula helenium, Dianthus stenocalyx. The investigated area phytodiversity is represented by meadow and psammophytic species of vascular plants: Calamagrostis epigeios, Agrostis vinealis, Poa pratensis, Koeleria cristata, Nardus stricta, Sieglingia decumbens, Anthoxanthum odoratum, Festuca orientalis, Juncus gerardii, Botrychium lunaria, Genista tinctoria, Solidago virgaurea, Euphrasia pectinata, Stellaria graminea, Hieracium villosum, H. umbellatum, Polygala sibirica, Plantago lanceolata, Equisetum arvense, Achillea submillefolium. For the five plant species listed in the Red Data Book of Ukraine, the distribution maps within the area of proposed preserve are given.
