General biosecurity comments

EU-regulated fungal pathogen of conifers with Douglas fir (Pseudotsuga menziesii) and grand fir (Abies grandis); both grown in the UK for forestry purposes; being particularly susceptible. EU regulation helps to mitigate risk of introduction; but should be reviewed to consider the need for specific import requirements for conifer wood.

General biosecurity comments

Fungal pathogen from North America which can affect tree vigour and timber production for a number of conifer species; including those commonly grown for forestry purposes in the UK. Management practices (such as stump treatments) carried out against native fungal species may be helpful in controlling this non-native species if introduced; although such practices may not be carried out for those tree species known to be tolerant (Abies grandis) to the native species.

About this section

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.
