General Comments

Known vector (beetle Platypus quercivorus) and fungal pathogen causing impacts on oak in Japan leading to potential tree mortality. Potential additional vector beetle species are present in the UK with the highest risk pathway likely to be timber. A PRA will help to further assess the risks.
