When did Buddleja davidii become invasive in Slovenia?

Abstract

Butterfly-bush (Buddleja davidii) is globally widespread invasive alien plant that originates in China. In Slovenia, a switch from benign naturalized plant to invasiveness occurred just recently, so in the last decade it has been spreading rapidly in the sense of geography and also forming viable competitively strong populations in (semi-)natural habitat types such as abandoned quarries, rocky slopes and river banks. In the article its spreading is presented with some older overlooked records and several new records that more than double our knowledge of the species' distribution in Slovenia. These data strongly confirm that it can be recognized as invasive alien species also in Slovenia, owing to its successful spread to natural habitat types in several parts of the country in the last decade.
