Ash Dieback Disease

Debate between George Freeman and Thérèse Coffey

Monday 12th November 2012 Commons Chamber

[George Freeman (Mid Norfolk) (Con)]

I speak as the Member of Parliament for Mid Norfolk, which sits right at the heart of the Norfolk cluster of the disease, and as the chairman of the all-party parliamentary group on agricultural science, which is taking a close interest in the matter. I know that all colleagues agree that this outbreak is a serious problem for our forestry industry and our landscape. I welcome the urgency of the reaction shown by the Secretary of State and the Department for Environment, Food and Rural Affairs team, and the professionalism with which they have handled the issue. More than 100,000 trees were felled in the summer, and the biggest ever survey of ash trees has been conducted. We have also seen several Cobra meetings, a national summit and an immediate ban on imports.

Outbreaks of disease that affect our biodiversity are never easy to manage, and it ill behoves the hon. Member for Wakefield (Mary Creagh) to criticise the Government in the way she did. Her words were somewhat at odds with the reaction of the former Secretary of State, the right hon. Member for Leeds Central (Hilary Benn), who I think all colleagues would agree has dealt with the matter in an extremely responsible way. He has also sat in the Chamber today and listened to the entire debate.

The hon. Member for Brent North (Barry Gardiner) is a former forestry envoy, and it was interesting that he devoted his speech largely to criticising the Government, rather than talking about the responsibility of the previous Administration. The truth is that this is a wake-up call for us all, as my hon. Friend the Member for Richmond Park (Zac Goldsmith) has said, and it is unhelpful wilfully, negligently or merely incompetently to distort the scientific evidence, to peddle petty personal conspiracy theories or to scaremonger.

I welcome the Minister’s clear, careful account of the issue. I particularly welcome his reassurance that the disease is not spreading, and that funding for plant health has not been cut—indeed, it has increased. I strongly endorse his acknowledgement of the role of the many voluntary groups and charities that have helped to support the Department’s work. The key now is to focus on what we can do to prevent the spread of the disease. We must use the British science base to explore all possible avenues—not least, resistance—and to put in place a proper framework for biosecurity.

The Government have taken a series of important steps in relation to prevention, and it is important to acknowledge the Minister’s assertion that the disease is not spreading now. We have some time in which to put in place a proper framework, which is why a responsible reaction from Members on both sides of the House is important. I also welcome the launch of the tree health action plan and the imposition by the Secretary of State of an immediate ban on imports. Unfortunately, however, the scientific evidence shows that because the disease has been allowed to incubate in this country for many years—probably between 10 and 15—we might not be able to eradicate it. Our ash population could be facing a serious epidemic.

[Dr Thérèse Coffey (Suffolk Coastal) (Con)]

Seven or eight outbreaks of the disease have been identified in mature woodlands in my constituency, yet in one of those woodlands no ash trees have been planted for 20 years. Is it not therefore plausible to suggest that it could be carried in on the wind or by birds, especially in the light of the maps of the infected sites?

[George Freeman]

My hon. Friend makes an extremely good point based on the evidence in her own constituency, which also sits at the heart of the East Anglian cluster. She allows me to draw attention to the map, which is extremely compelling. It shows that 90% of all incidences of the disease are down the east coast, and most of those are on the bit of the east coast that is closest to Europe and that is affected by the prevailing winds from the east.

I am quite pessimistic about the long-term prospect of our controlling and stopping the disease, but there is a glimmer of optimism in the science of resistance, and it is to that subject that I shall now turn. There are signs that some of our older ash trees might have developed a resistance to the disease, and we now have an opportunity to show scientific leadership by throwing as much resource as possible into identifying a solution.
