This PRA was used to support the listing of this species in the  Invasive Alien Species Regulation (Regulation (EU) 1143/2014).

Main conclusions

The results of the PRA show that A. saligna poses a high risk to the endangered area within the European Union under current climate (i.e. significant parts of the Mediterranean Biogeographical region, but also countries along the Atlantic and the Black sea coasts for the ‘pruinescens’ subspecies), with a low uncertainty (figure 5 in Appendix 4). Impacts in the current introduced range are high, and although the risk of further introduction in the European Union is considered as low, there is a moderate perceived risk of spread from established populations, facilitated by water and movements of soils contaminated by seeds or fragments of root suckers. Furthermore, the endangered area is likely to increase a lot during the coming decades due to climate change (figure 6 in Appendix 4).
