Sir Nicholas Soames: To ask the Secretary of State for Environment, Food and Rural Affairs, what estimate she has made of the scale of Acute Oak Decline (AOD); what research her Department is undertaking into AOD; and what steps she is taking to tackle AOD.

George Eustace, Minister of State for Farming, Food and the Marine Environment: Over the past five years Forest Research, in collaboration with Rothamsted Research, has conducted a systematic survey to model the distribution of acute oak decline (AOD) in England and Wales. The results show that the condition currently affects several thousand oak trees, mostly across East Anglia, the Midlands and southern England.

Since 2013, Defra has invested £1.1 million in research to understand the causes, distribution and scale of AOD in the UK.

Earlier this year Defra, in collaboration with the Research Councils, the Scottish Government and the Forestry Commission, launched a further £2 million call for research proposals on ‘oak health’ and Phytophthora. The successful bids from this call are due to be announced shortly.
