The number of alien plant species has more than tripled over the last 25 years. This is the finding of a study by European scientists who evaluated the data from 48 European countries and regions. A total of 5789 plant species were classified as alien. Of these, 2843 originating outside of Europe, according to the researchers. By contrast, in 1980 only 1568 alien species were registered.
