Ash Dieback Disease

Graham P Jones Excerpts

Monday 12th November 2012 Commons Chamber

[Mary Creagh]

One can argue about the system for woodland grants, but we would argue that it may be much cheaper to grow the ash saplings abroad, which is perhaps one of the reasons landowners choose to buy them from abroad. It is also perhaps why the Horticultural Trades Association wanted the Government to regulate back in 2009, so that there was a level playing field in the industry and so that it did not impose its own voluntary moratorium, allowing others to import cheaper saplings and undercut the market.

What happens next? The Forestry Commission has conducted a tree survey over 29,000 hectares, an area the size of Wales. It has sampled four woodland sites in each 100 square kilometres, giving us a rough idea of where to look next for the disease. As the surveys continue this winter, more disease sites will be found. I have a number of questions for the Minister. First, will he now review the scientific advice he has been given on other tree diseases? Does he have any plans to restrict trade in other species of trees on a precautionary basis? Does his import ban apply to resistant strains of ash species, which are now present in Denmark and, I believe, Lithuania?

Secondly, have the detection and management of the disease been hampered by the cuts to the Forestry Commission? Its budget is being cut from £47.5 million in 2010-11 to £36.2 million in 2014-15. Some 530 staff posts have already been cut and seven regional offices closed. Thirty-eight posts have been cut in Forest Research, with another 22 earmarked to go. These are the scientists and experts who lead the fieldwork on tree health, and they are in the front line in our fight against this disease. Will the Minister review their posts? What assessment has he made of the impact of his Government’s cuts to the Forestry Commission on tackling tree disease?

Thirdly, in 2009, at the request of my right hon. Friend the Member for Leeds Central, the former Secretary of State, the Forestry Commission established a biosecurity programme board, bringing together the industry, NGOs, Forest Research, the Scottish Government, and the Food and Environment Research Agency. What has happened to that board? It appears to have met just twice—in November 2009 and July 2010. The minutes of the final meeting on the Forestry Commission website show that forestry staff had concerns about the Government’s publicity freeze and cancellation of much of the publication budget, yet I know from my discussions over the weekend that the board appears to have continued meeting informally. Was it affected by the re-organisation and cuts at the Forestry Commission?

The Secretary of State told the BBC last Friday that he is re-ordering his Department’s priorities and said:

“There will be some things we do in DEFRA now that we are going to have to stop doing.”

What are those things? And how does he know that not doing them is not storing up a fresh disease problem in the future in another area? Other areas of DEFRA will be quaking as they anticipate fresh cuts on top of the worst settlement of any Government Department.

What contact has the Minister had with councils that are in the front line of dealing with this disease? What advice has he provided to them about council parks? Should they be undertaking surveys of their own trees? The Local Government Association has informed lead officers, but nothing seems to be coming out of the Department for Communities and Local Government.

[Graham Jones (Hyndburn) (Lab)]

On that matter, I wrote to my local authority, Rossendale borough council, to which I had this reply:

“The council have not received any prior notification”—

this was last week—

“regarding the disease and only became aware of the issue when it was announced in the media last week.”

Is that not a shambles? Does my hon. Friend not find that staggering?

[Mary Creagh]

I find it amazing that a Department that is presumably present at a Cobra meeting to co-ordinate a national emergency response to a disease is not putting out any formal guidance to councils. Perhaps the Minister can explain that gross dereliction of duty.

Were Transport Ministers present at Cobra meetings? The Highways Agency is constantly planting new trees along its motorway network. What about Network Rail, which has been undertaking a tree-felling programme this summer along the east coast main line, perhaps unwittingly spreading the disease up the east coast? We need answers to these questions.

In conclusion, the British public care deeply about their forests. We saw that in the overwhelming opposition to the Government’s plans to privatise them last year. I am glad to see the right hon. Member for Meriden (Mrs Spelman) in her place; perhaps she can shed some light on some of the history of the disease. The forests now face a new and devastating threat from ash dieback disease. There is a bitter irony here: the Government who wanted to privatise the forests have now been forced to make further drastic cuts in order to fight tree disease. As the triennial review of Natural England and the Forestry Commission approaches, we will watch carefully to ensure that the Secretary of State does not embark on a further round of destabilising upheavals.

We await the scientists’ first report, which will be available by the end of November. We will support the Secretary of State when he does the right thing, but we will challenge him when we feel that he is taking a wrong turn. We will not be excluded from his decision making. This is a vital issue for the British countryside and for our natural environment. All parties must learn the lessons of this disease, slow its spread and safeguard our forests for the next generation to enjoy.

[The Minister of State, Department for Environment, Food and Rural Affairs (Mr David Heath)]

Earlier today I had an opportunity to see for myself the effects of Chalara fraxinea in woodland near Canterbury and to meet some of the 500-plus people who have worked around the clock to complete a survey on an unprecedented scale aiming to identify signs of the disease. I want to offer my sincere thanks to them all. They are not all Forestry Commission staff or employees of the Food and Environment Research Agency; a great many others have joined in and worked so hard to complete what has been a massive undertaking, including volunteers who have given up their time to help. As of today, the results of the survey show 155 cases of ash dieback caused by Chalara across Great Britain: 15 in nursery stock, 55 in recently planted sites and 85 in the wider environment. Further suspect cases are currently under investigation and we will continue to provide updates on confirmed cases on the Forestry Commission website.

I am grateful to the hon. Member for Wakefield (Mary Creagh) for giving me the opportunity to set out for the House the decisive action the Government have taken to tackle the threat from Chalara fraxinea and to lay to rest some of the myths she has perpetuated in recent weeks.

[Graham Jones]

The Minister said that he has received an assessment of the number of trees infected. Perhaps he could enlighten me on the answer I have received from Rossendale borough council. It states:

“Currently we are not aware of any infected trees in Rossendale. However, the announcement regarding the disease came when our ash trees had already dropped their leaves for winter and, therefore, it is not possible to identify symptoms positively until next spring at the earliest.”

[Mr Heath]

Clearly we need to educate the hon. Gentleman’s borough council a little more on the signs and symptoms to look for with regard to Chalara fraxinea. It is possible to see retained leaves that are diseased and lesions on the bark, as I saw this morning. Summer is not the only time of year when it is possible to see dieback. I understand that the borough council officials have been unable to see signs of Chalara in his area, but that is because we have found no signs of Chalara in the area either. It is a long way from the English channel.

--- Later in debate ---

[Mr Heath]

The hon. Gentleman, who purports to know about science, really ought to understand scientific method. I think that a theory from our chief scientific adviser, supported by all the experts in Britain and Europe, is rather better than one propagated by the hon. Member for Wakefield to support her conspiracy theory.

As I have said, these conclusions have been endorsed by the leading experts, who have reviewed the evidence about Chalara to help us to understand how it is spread, its impact on our ash trees, and how we might tackle it. A summary of their conclusions was sent to all Members on 7 November and published on 9 November. As my right hon. Friend the Secretary of State said in a written ministerial statement last Friday, the advice from the scientists

“is that it will not be possible to eradicate Chalara.”—[Official Report, 9 November 2012; Vol. 552, c. 49WS.]

The experience in the rest of Europe is that there is no effective treatment. However, that does not mean the end of the British ash. While young trees succumb to the disease fairly quickly, mature trees with the infection can live for many years. We know that the Danes have identified a small number of trees that seem to be resistant to Chalara. That knowledge buys us some time, so what can we do?

It is clear that the Government alone cannot tackle this threat. On 7 November, we convened a summit that brought together more than 100 representatives of the forestry and horticulture industries and environmental groups to advise us. There was a broad consensus on the evidence and on the action that we should take. The strong message is that we should not be panicked into taking draconian action that could be futile or counter-productive. The lesson of the Dutch elm disease of the 1970s is that much of the costly action taken then simply did not work. We have a window over the next few months while the disease is not spreading, and that will enable us to develop the right approach. The disease is not spreading, incidentally, because this is not the sporulating season for it. There are no fruiting bodies, and there are therefore no spores—unless the hon. Member for Wakefield has a theory that there is winter sporulation as well.

[Graham Jones (Hyndburn) (Lab)]

I am grateful to the Minister for giving way—he is being very generous with his time—but why has he not written to local authorities about this? He has written to neither Hyndburn borough council nor Rossendale borough council. Will he tell us, and the local authorities, when he intends to write to them explaining how he will intervene to tackle the issue?

[Mr Heath]

I expect local authorities to show a little common sense. The whole country is benefiting from the very good Forestry Commission website, which is providing all the information that they need in order to identify the disease. We bring the Local Government Association into the inner workings of government at the Cobra committee, so it can provide information to local authorities. I do not think there needs to be a letter from me just to add to the pile of correspondence—and reduce the number of trees in this country in the process—rather than authorities taking sensible advice.

Building on the advice of the summit, on Friday the Secretary of State announced the immediate action we would be taking. Newly planted diseased trees and diseased trees in nurseries will be traced and destroyed, as young trees that are infected succumb quickly. Mature trees will not be removed, however, as they are valuable to wildlife and take longer to die. They can help us learn more about the genetic strains that might be resistant to the disease. Infection does not occur directly from tree to tree—a point which, again, is lost on some.

Better understanding of the disease will be built through research and surveys, looking not only for diseased trees, but for those that show signs of resistance to Chalara. The search for the disease will include trees in towns and cities—a point made by the hon. Member for Edinburgh North and Leith (Mark Lazarowicz)—as well as in the countryside. It will also include building partnerships with a range of organisations beyond government and providing advice to foresters, land managers, environmental groups and the public about how to identify diseased trees and those likely to be resistant to the disease, and what to do with that information.

Organisations such as the Woodland Trust and the National Trust have endorsed this approach. None of the action we have taken to date or that is planned involves restricting access to the countryside. The scientists are clear that there is no need for that. We want to ensure rural businesses continue to operate and that people who want to enjoy the countryside can do so.

These are just the first steps, and by the end of November we will have developed a comprehensive control plan that will set up longer-term action to tackle Chalara. It will consider measures such as designating protected zones and improving diagnostics and biosecurity. Our approach will, for the first time, look at how we can mobilise the many people who love our countryside and value the trees in our towns and cities, in order to help us tackle this disease. For the longer term, we will learn the lessons from the response to Chalara and use them to consider our strategic approach to plant health. The Secretary of State has already told the House that he is prepared to look at radical options. He will come back to the House in a few weeks to report on progress.

I believe we have taken all appropriate actions to deal with what is a very serious situation.
