The share of present invasive species (eg. Robinia pseudacacia, Ailanthus altissima, Buddleja davidii, Erigeron annuus) in the last decade shows an increasing trend. An increase in the share of invasive species is evident along the great lowland rivers Sava, Mura and Drava, as well as along the Kolpa river. In higher areas of Slovenia, particularly in the Alps and the Dinaric region, invasive species are very few or entirely absent. However, a notable increase in their share along the western border of the Dinaric region raises concerns.
