A bacterial disease with a wide host range detected in Corsica. Although EU regulated; there remains some concern about the risk of introduction. This subspecies is known to be able to thrive in cooler climates. Should an outbreak occur; there would be a need for eradication action which would result in environmental and social impacts.

Ambrosia beetle affecting a wide range of trees and woody hosts. Widespread in Europe and elsewhere and now present in the south of England. Impacts can be reduced by good silvicultural practices. Surveillance is being carried out to better determine distribution.

Ambrosia beetle which can affect a wide range of broadleaved trees; widespread in Africa; Asia and parts of the US; with outbreaks in France and Italy. The UK climate is unlikely to be suitable for the pest to thrive and cause significant damage but needs to be investigated through research. A Europe-wide PRA will help inform the case for EU regulation. Premises involved in importing wood and host plants from Italy in particular; where official measures are not being taken; should source material carefully.
Our plants are under greater threat than ever before. There is increasing movement of plants and other material traded from an increasing variety of sources. This increases the chances of exotic pests arriving with imported goods and travellers, as well as by natural means. Shoot is working with Defra to help members to do their part in preventing the introduction and spread of invasive risks.
