Plant invasion of habitat types

Since plant invasion is one of the most important factors threatening biodiversity, we pay special attention to it. Here we show the geographic pattern of palnt invasion and importance of the studied alien invasive plants in the semi-natural habitats.Habitat types with low area or with low reliability of invasion records (e.g. floating vegetation, where the cover of aliens were underestimated) are not shown.
