General Comments

A disease complex involving an ambrosia beetle and fungus, present in South California and Israel, which could affect English oak and other broad leaved species if introduced to UK. Climate is likely to be a limiting factor regarding establishment. Watching brief needed on pest spread into areas with cooler climates and to be added to the EPPO Alert List in response to threat to Southern Europe. A UK PRA will help inform the case for EU regulation.
