Increasing spread of non-native plants on islands since one thousand years

A global study published in Ecological Letters shows with hitherto unmatched differentiation the extent to which non-native plants have spread to oceanic and coastal islands over the last 5,000 years. Researchers at the UBT and at universities/ research institutes in Great Britain, Norway, Austria, Spain, Australia and New Zealand have compiled a dataset covering the vegetation of 29 islands. This was based on analyses of fossil pollen and the current state of research on the classification of plants as native or non-native.
