Potential invasive herbaceous ergasiophygophytes from the collections of the Donetsk Botanical Garden

Among herbaceous ergasiophygophytes of the Donetsk Botanical Garden, 21 species show high adaptive potential and are classified by us as potential dangerous invasive ones. Petrosedum reflexum (L.) Grulich, Solidago canadensis L., Arrhenaterum elatius (L.) J. Presl & C. Presl are of the greatest danger as they are likely to have «transformer» status soon, if not regulated in their distribution. The species confinement with habitats types according to their degree of naturalness, type of maintenance, luminance and development of soil cover was analyzed.
