New invasive alien plant species recommended for regulation in the EPPO region
Four invasive alien plant species have been added to the EPPO A2 List in 2017 and therefore recommended for regulation within the EPPO region. All species were risk assessed within the framework of the LIFE funded project: Mitigating the threat of invasive alien plants in the EU through pest risk analysis to support the EU Regulation 1143/2014. The four species (table 2) include three aquatic species (Gymnocoronis spilanthoides, Pistia stratiotes and Salvinia molesta) and one vine (Cardiospermum grandiflorum). All aquatic species were assessed as a high phytosanitary risk to the EPPO region. C. grandiflorum has a moderate phytosanitary risk to the EPPO region. Two additional species, Hygrophila polysperma (Acanthoideae) and Cinnamomum camphora (Lauraceae), were presented to the EPPO Working party on Phytosanitary Regulations with a low phytosanitary risk, and thus will not be recommended for regulation. Under current climatic conditions, the latter two species are not predicted to establish within the natural environment in the EPPO region.
