Question to the Department for Environment, Food and Rural Affairs:

To ask Her Majesty’s Government what plans they have to list all the UK's tree and plant species under threat from pests and diseases found in plants imported to the UK from the EU.

We are committed to doing all we can to prevent plant pests and diseases reaching our borders and to build the resilience of our trees and plants. Our approach, led by the Government Chief Plant Health Officer, involves the systematic, proactive screening of potential new and emerging risks, which are listed in the Plant Health Risk Register.

There are regulations on importing plants and products from outside the UK where it is known that certain pests or pathogens are present. These are updated regularly, in response to new evidence, such as that published by the European and Mediterranean Plant Protection Organisation. We are working collaboratively with the EU and broader international community, industry, NGOs, landowners and the public to reduce the risks of pests and diseases entering the country and the impact of newly established pests, including substantial programmes of work on the oak processionary moth and ash dieback.
