Journal of Native and Alien Plant Studies| Summary: | The article is devoted to the study of tree and shrub plant species that spontaneously invasively colonize anthropogenically undisturbed steppe ecosystems. The species composition, number and biometric characteristics of tree and shrub plant species are determined. It was established that there are 22 species, among which 8 show the greatest invasive activity, in 6 studied natural beams. These are: Cotinus coggygria Scop., Crataegus fallacina L., Prunus divaricata Ledeb., Prunus stepposa Kotov, Pyrus communis L., Rhamnus cathartica L., Robinia pseudoacacia L., Ros corymbifera Borkh. According to the Serensen index of species composition of tree and shrub plants, comparing the slopes of beams of different exposures, it was found that steppe tracts have different similarities between the slopes, but the highest figure was observed for Balka Demurynа (80%). |
