Abstract
A long-term (2007−2018) inventory of the collection of woody plants of the Botanical Garden of the Belgorod State University (NRU “BelSU”, Belgorod, Russian Federation) identified 145 introduced tree species which are able to disseminate by seed and vegetative modes in local conditions of the region. Data on species-ergasiophytes in parks and private gardens were also used in the study. The spatio-temporal aspect was accounted for the classification of alien introduced woody species according to the degree of their naturalization. Among them, the largest number of species is represented by epecophyte-colonophytes (60.0%), agriophytes-ephemerophytes (22.0%) and epecophytes-ephemerophytes (10.0%). Colonophytes-agriophytes that account for 8.0% are represented insignificantly.
The most “dangerous” for the region’s natural biocenoses introduced species running wild from the culture are: Acer negundo, Amorpha fruticosa, Caragana arborescens, Cerasus vulgaris, Elaegnus angustifolia, Fraxinus pennsylvanica, Hyppophae ramnoides, Lonicera tatarica, Parthenocissus inserta, Prunus cerasifera, Robinia pseudoacacia, Sambucus nigra, S. racemosa, Ulmus pumila.
Keywords: Introduction of plants, ergasiophytes, phytocenosis, self-sowing, dissemination, botanical garden.
