РАРИТЕТНА КОМПОНЕНТА УРБАНОФЛОРИ ПЕРЕЯСЛАВА

Abstract

The article presents data on the current state of the rare component of the urban flora of Pereiaslav. Urbanization is one of the most powerful factors of anthropogenic impact on nature, which causes radical changes in the species composition, structure, evolutionary development of flora and fauna on the territory of settlements and their environs. The flora of the city becomes the most important in the environment of the person and therefore requires special research and establishment of ways to restore the natural biological diversity, in particular, the conservation of fragments of natural flora and vegetation in the city. One of the important tasks of biodiversity conservation is the study of the location and protection of the most vulnerable species - rare, relict species listed on various levels. In addition to the presence of well-preserved fragments of natural vegetation, the unique character of Pereіaslav also lies in its geographical location. The city is located on the terrace of the middle reaches of the Dnieper River, through which passes the Dnieper meridional eco-corridor, which provides for the resettlement of plants in different zones. Given that the left-bank part of the Middle Dnieper is characterized by extremely transformed vegetation cover, every area of natural vegetation in this territory, including the territories of cities where the enclaves of natural vegetation have been preserved, which is, in particular, the studied city, should be considered as a zone of potential re-naturalization. It is established that the flora of Pereіaslav and its surroundings has 968 species of vascular plants, 66 species of mosses, 28 species of lichens and 146 species of algae. It is established that rare vascular plants cover 3.5% of the total floral composition of the natural fraction of urban flora. Inventory of flora reveals 34 rare protected plant species: 10 of which are listed in the Red Book of Ukraine (2009), 4 of them are listed in the Convention for International Trade with Endangered Species (CITES), 2 of them are listed in the Berne Convention, 1 of them are listed in the European Red List, 23 of them are included in the regional list Kyiv region. A brief description of the species and their location is given.
