in Portugal, the most area occupied by this species corresponds to plantations by Man and not natural dispersal/invasion.
The species is included as invasive because, on one hand, it has seen its invasive behaviour in many situations in the country
and, on the other hand, its wide distribution creates a high propagule pressure which constitutes an increased risk.
