EPPO Express PRA for Triadica sebifera
The results of this PRA show that Triadica sebifera poses a high risk for biodiversity to the endangered area (Mediterranean and Black Sea biogeographical region) with a high uncertainty. Triadica sebifera is an aggressive invader in the southern United States and Australia. The most serious impacts of invasion appear to have occurred following widespread commercial and ornamental planting of the species (USDA 2008; Scheld and Cowles 1981; Bruce et al. 1997). While it displays broad habitat suitability, T. sebifera appears limited by cold winter temperatures and steep land gradients in the USA (Gan et al. 2009; USDA 2008). Warmer regions in the PRA area, specifically the Mediterranean, face the highest risk of T. sebifera establishment.
Plants for planting is the main pathway for entry into the EPPO region. The likelihood of entry is high with a moderate rating of uncertainty.
