Ash Dieback Disease

George Freeman Excerpts

Monday 12th November 2012 Commons Chamber

[Mary Creagh]

I am going on the empirical evidence, and I shall spend an extensive part of my speech reviewing the scientific facts, seeing how they have changed since they were first published last Wednesday—because they have—and going into great detail on that point.

[George Freeman (Mid Norfolk) (Con)]

Before the hon. Lady develops her theme of the Government’s having been caught short and not reacting properly, does she agree that the Department was alerted to the problem as far back as 2007, two years earlier than has been reported, and that the budget for studying tree disease was cut by more than half in real terms in the years leading up to 2010?

[Mary Creagh]

There has been confusion on both sides of the House about what the former Secretary of State, my right hon. Friend the Member for Leeds Central (Hilary Benn), who is in his place, did or did not do. He asked the Department for Environment, Food and Rural Affairs to do a thorough search of all the ministerial papers he saw on ash dieback, which has shown that he did not see the correspondence between the Horticultural Trades Association and the Forestry Commission about a possible import ban. The only mention of ash dieback was in a briefing note in February 2010, in which the disease was listed as absent from the country. The hon. Member for Mid Norfolk (George Freeman) chairs the all-party group on life sciences, so he should know that the way the disease has been discovered is still evolving.

In 2009, it was thought that the fungus that caused ash dieback was already present in the UK. It was only subsequently that a new virulent species causing ash dieback was discovered. The science changed in 2010, when a new pathogen, Hymenoscyphus pseudoalbidus, was identified as the fungus causing the disease. I advise all hon. Members to read an article by Andy Coghlan in the New Scientist of 31 October that gives the scientific chronology of the disease. I also have a copy of the scientific paper in Forest Pathology in which the change was first discovered, which was printed in 2011.

What did my right hon. Friend the Member for Leeds Central do? He published the “Forestry Commission: Science and innovation strategy for British forestry 2010-2013” on 1 April 2010. It stated:

“Over the next five years we will increase our budget for monitoring and biosecurity research particularly with regard to tree health to 15% of our research spend.”

Even as late as autumn 2011, the Forestry Commission pathology bulletin confirmed that Britain was clear of the pathogen.

--- Later in debate ---

[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.

[Mr Tom Harris (Glasgow South) (Lab)]

May I make a small technical point? The hon. Gentleman just mentioned prevailing winds from the east, but I think that he meant the west.

[George Freeman]

The hon. Gentleman has obviously not spent enough time in the east of East Anglia, where there are often winds from the north and from the east.

[Mr Harris]

Prevailing winds?

[George Freeman]

I stand corrected if I said “prevailing”. There are frequently winds from the east and the north-east and, as the map demonstrates, it is perfectly possible that the disease could have been carried over from mainland Europe.

The scientific research into resistance offers us an important opportunity to identify genetic markers and traits that would allow us to establish a breeding stock of clean, new ash strains, and to unlock as much funding as possible from the European budget to support UK leadership in that field. This is an opportunity for us to promote British plant and forestry science in the context of the European market. I should like to make a small plea to the Minister on behalf of Norfolk. It is perhaps the worst-affected county. It is also home to the John Innes Institute and the Norwich research park, and if there is any scientific work to be done in this regard, I should like us to be at the front of the queue. Our county has a lot to offer.

[Mrs Caroline Spelman (Meriden) (Con)]

My hon. Friend has considerable knowledge of these matters, and I am sure he is aware that where the disease has been established for longer, there is a greater chance of finding resistant varieties. The Poles believe that they might have some resistant varieties, but there is now great disappointment in continental Europe because it was thought that we might have resistant varieties because there was no incidence of the disease here.

[George Freeman]

I am grateful to my right hon. Friend the former Secretary of State. I am sure that the Minister will pick up on her extremely well-made point.

In the context of biosecurity in the UK, this is a wake-up call for us all. For far too long, we have not taken our biosecurity seriously enough. Over the past 15 years, we have seen a significant—and generally all to the good—globalisation of trade in commodities and products. We have also seen substantial climate change.

[Neil Carmichael (Stroud) (Con)]

Does my hon. Friend agree that we must have a clear understanding of the threats to our biosecurity, and that we should develop international contacts to enable us to identify those threats?

[George Freeman]

My hon. Friend makes a good point.

This outbreak presents us with an opportunity to establish our leadership in this important area of science. Over the past 15 years, we have seen a huge globalisation of trade in agriculture, plants and other commodities, as well as substantial climate change. That changes the context in which we should view the import and export of those goods. The UK’s biosecurity is of strategic national importance, as my hon. Friend the Member for Richmond Park eloquently pointed out. Colleagues who have visited Australia and the USA recently will know how seriously those and other countries take these matters. A person can hardly leave an aircraft without being sprayed, disinfected and checked, and without having their luggage checked for seeds. The outbreak represents a wake-up call for us in that context as well.

I welcome the Secretary of State’s strong leadership on this matter, and his highlighting of the potential for Britain to grasp the nettle and set out a new framework for biosecurity. If we can draw on our strengths in plant science, we will be able to turn this crisis to at least some advantage for the UK, and to establish ourselves once again as an island of biosecurity in a Europe that is awash with a number of plant and animal diseases, to the benefit of our landscape and of our agriculture and forestry industries.
