Both the EPPO PRA according to Standard PM 5/3  and the report of the PRA are available.

If A. anxius entered the PRA area, the pest would have a very high probability of establishment wherever birch is present. It is adapted to a wide range of climatic conditions and would find susceptible hosts. Eradication or containment would be difficult due to the hidden life stages of the pest and the fact that it might not be detected before it has already established and caused damage. It is also very likely that the pest would spread (natural spread as it is a strong flier; human-assisted through movement of infested birch material). Due to the higher susceptibility of European and Asian birch species, it is expected that the pest would have major economic consequences where birch is present in the PRA area. On the whole, introduction would result in high mortality of birch throughout 5 the PRA area, and major economic impacts (including major environmental impacts).

2021: The PRA report was modified to clarify the phytosanitary measures recommended
