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

To ask His Majesty's Government what steps they are taking to protect the health of trees in the UK against the disease ash dieback.

Since ash dieback was first detected in the UK, we have restricted the movement of ash trees from outside Europe to protect against other strains of the pathogen, and invested more than £8 million to advance our scientific understanding of this disease.

We have conducted the world’s largest screening trials for tolerant trees and have planted over 3000 trees of 1000 genotypes in the first UK archive of tolerant ash. They have been drawn from a wide geographic spread, and new trees will continue to be added, to maximise the genetic diversity in the collection and facilitate the possibility of a future breeding programme of resilient ash.

Guidance for landowners on managing diseased ash has also been published, including a toolkit for Local Authorities, which has been downloaded nearly 20,000 times. Defra also provides restoration grants, to support replanting with alternative species where ash dieback is present.

We continue to invest in research to enhance our understanding of the disease, improve management and identify resistant trees.
