Vulnerability Of Habitats Of The Emerald Network To Invasions Of Alien Plants In Pridneprovsk Left-Bank Forest-Steppe (Ukraine)

Abstract

The paper presents the results of research on the populations of alien plant species of the Pridneprovsk Left-Bank Forest-Steppe, which are able of being invasive in the habitats of the Emerald Network. The received data are the result of many years of research carried out during period 2000-2018. In the investigated territory, we identified 277 alien plant species. Most are kenophytes, epecophytes, ephemerophytes, and colonophytes. They are distributed mainly in natural and seminatural phytocoenoses. Most species are dominant and produce an influence on the structure of habitats and biotopes. Populations of alien plant species were identified in 33 types of habitats of the Emerald Network of the Pridneprovsk LeftBank Forest-Steppe and have different hierarchical levels.
