Ash Dieback Disease

Nigel Evans Excerpts

Monday 12th November 2012 Commons Chamber

[Mr Barry Sheerman (Huddersfield) (Lab/Co-op)]

On a point of order, Mr Deputy Speaker. The Minister has not mentioned one very important point: the cost to the landowners in my constituency who have bought many thousands of saplings and who are now having to destroy them.

[Mr Deputy Speaker (Mr Nigel Evans)]

That is not a point of order for the Chair. The Minister is responsible for his own speech. Indeed, Mr Sheerman, you have only just come into the Chamber.

[Mr Heath]

I am most grateful to you, Mr Deputy Speaker.

As I was saying, this is a very difficult situation, and I believe we have taken all appropriate steps. To repeat something I said in response to the previous urgent question, we are not going to engage in the blame game. This is not a question of attributing blame to anyone; it is a question of getting things right, by working with everybody who has a genuine interest in the future of our forests and woodlands and making sure they are mobilised in the most effective way to deal with Chalara. Those who want to peddle conspiracy theories can do so if they wish; we will get on with dealing with the disease.

I am delighted to follow the hon. Member for Richmond Park (Zac Goldsmith), who made many of the points I wished to make.

Serious and genuine questions need answering about the genesis of Chalara fraxinea in the UK. Did the Horticultural Trades Association warning in 2009 go unheeded by DEFRA officials? Were Ministers made aware of that warning? When they were informed on 3 April of the infection in Buckinghamshire, why did they not impose a movement ban? When Crowders nursery in Lincolnshire notified officials in June this year that the disease was found in 15 of its trees, did DEFRA officials really issue it with a notice to stop it taking action? Did they put trade rules above environmental health? When the disease began to take hold in Poland in 1992 and other parts of continental Europe later on, did the EU take adequate steps to regulate and control its spread?

Is it credible to claim that wind-blown spores reached the UK from across the sea, from Denmark, given that scientific advice states that wind-blown spores can spread 20 to 30 km per year and that local spread may be via wind, rain, splash or even transmission by insects, but that over longer distances the risk of disease spread is most likely to be through the movement of diseased ash plants? Given that the UK introduced national measures to prevent the entry and spread of the disease on October 29, why did it claim that it could not do so to nurseries and growers previously? Did UK nurseries that became aware of the danger of Chalara fraxinea then stop importing seedlings from suppliers in infected countries, or did they rely on Government advice, rather than their own trade association?

All those questions will no doubt eventually be answered, and no doubt not all of them without embarrassment to politicians, officials and the industry. My focus today, however, is on examining the response that the Government must make to the increasing threat that our landscape and biodiversity face from climate change and the new vectors of disease that climate change has brought with it. In its excellent report published earlier this year, the Independent Panel on Forestry specifically addressed the need

“to see our wooded landscapes, in both rural and urban settings, being better protected from, and more resilient to future risks such as climate change, pests and diseases.”

It specifically recommends that the Government

“should speed up delivery of the Tree Health and Plant Biosecurity Action Plan by additional investment in research on tree and woodland diseases, resilience and biosecurity controls.”

The key question arises: have they speeded up the delivery of the action plan? I remind the House that the body meant to examine this was set up by my right hon. Friend the Member for Leeds Central (Hilary Benn), the Secretary of State for the Department for Environment, Food and Rural Affairs in 2010. The key diseases and pest identified at that time were sudden oak death syndrome, oak processionary moth and Phytophthora ramorum in larch. I believe that Chalara fraxinea was mentioned only as a disease predominantly in Europe that might manifest itself in the UK.

Perhaps one of the more foolish cutbacks imposed by the Government has been the freeze on public information spending. I ask the Minister how on earth the Government propose to combat infectious diseases in plant health if they constrain their own ability to communicate directly with growers and the industry, and rely on the passive mechanism of their own website. It has been estimated that the changing risks arising from climate change and the new vectors of disease will result in a decline in timber yield in England of up to 35% by 2080, according to the Forestry Commission’s report “Climate Change Risk Assessment”, published in February.

In the past 12 months, the Forestry Commission has reported increasing incidence of Phytophthora lateralis, which attacks Lawson cypress, Phytophthora ramorum, which attacks beech and rhododendron—itself a non-native invasive species, but now a part of the UK landscape—acute oak decline and Cryphonectria parasitica, which affects sweet chestnut. To these diseases, we must add pests such as the Asian longhorn beetle in broadleaf woodland, the pine tree lappet moth on native heath land, and oak processionary moth in beech and hornbeam—to name only a few of the most serious new threats.

The number of outbreaks of these pests and diseases has risen more than twelvefold over the past 40 years. It is one thing to identify these risks to our landscape, but it is quite another to develop a mitigation and adaptation plan to combat the way in which they might impact on our biodiversity and on the ecosystem services that our forests provide. Such a plan will not be cheap. Last year in the United States, the Animal and Plant Health Inspection Service’s eradication programme for the Asian longhorn beetle alone cost US$33 million.

I urge the Government to understand that it is not enough to have a plan to tackle Chalara fraxinea. They must develop a framework in which all the new vectors of risk that threaten our landscape can be tackled. That means having a clear understanding of the value of the ecosystem services that our trees and forests provide. The Government must look to the national biodiversity action plan and the national ecosystem assessment for a blueprint for a comprehensive response. The key message of the UK national ecosystem assessment begins:

“The natural world, its biodiversity and its constituent ecosystems are critically important to our well-being and economic prosperity, but are consistently undervalued in conventional economic analyses and decision making.”

Natural capital has not been properly accounted for, and the services that our forests provide through provisioning, habitat for pollinators, watershed protection and soil stabilisation are considered—

[Mrs Spelman]

I am not going to give way again. Moreover, one might have expected the trade press to have expressed its concern on the front pages of its publications.

We all need to share some responsibility and to redouble our efforts to spot the disease. I applaud the volunteers who have helped with the unprecedented survey of our woods and trees. As my action plan stated, collaborative working—of landowners, industry, academia, civil society and Government—is required better to protect the health of our nation’s trees. We need to pull together, not against each other, in the fight for tree health.

[Mr Deputy Speaker]

There are 10 minutes left. Perhaps three and a bit minutes each, and then everybody will get in.

[Neil Parish (Tiverton and Honiton) (Con)]

It is very sad that the House of Commons cannot come together today to tackle this disease. The Opposition’s attempt to land a blow on the Government in this regard is absolute nonsense. There is no doubt that, as the relevant map shows, a lot of the disease comes across from the continent. No Government, irrespective of their political persuasion, can stop what blows on the wind. Therefore, we must concentrate on how we are going to deal with this disease. We must look for ash trees that will be immune in future, so that we can take the seeds from them and grow them. As the hon. Member for Brecon and Radnorshire (Roger Williams) said, we do not want to see the decimation that we experienced with Dutch elm disease. Indeed, I saw that on my own farm: the decimation of massive trees that were hundreds of years old. We have never really recovered from that: every time a tree grows, it catches the disease again perhaps 10 or 15 years later. We want to ensure that the ash tree is there for the future.

We must also be certain that the single market, the great wonder of the European Union, is not abused. The trouble is that no Government can stop the import of ash trees until they have proved that they have the disease, and by that time it is too late. That really has to be put right. We are surrounded by water—let us hope that not every disease can be blown across the channel—and Britain could develop the same methods that Australia and New Zealand have developed in trying to keep disease out of the country. We must ensure that we breed ash trees in this country—that we do not export the seed to Holland, where the trees are then grown, and then import the trees back again. The industry itself must take some responsibility here. When the disease is on the continent, it is absolute nonsense to keep this trade going backwards and forwards. Given the existence of the single market, it is very difficult to stop it, but we need to change things.

I want Britain to have beautiful trees into the future. As Members have pointed out, there are many diseases out there that we need to tackle, so let us adopt a positive approach. I praise what Ministers and the Secretary of State are doing to analyse where all the diseased trees are located, so that we can act quickly. We cannot simply stop the disease by chopping down all the ash trees that have it—the saplings, yes; but the mature trees, we cannot. Let us hope that some of those trees survive and that from those, we can grow the great ash trees that we want to see.

The lesson in all this is that we cannot keep exporting and importing trees, bringing disease with them. I look forward to a positive message from Ministers on research and maintaining “fortress Britain” so far as growing trees and keeping out disease is concerned, and then perhaps repopulating trees across Europe. I repeat my first point: I am very sad that the Opposition have made such a thing of this. I respect what the right hon. Member for Leeds Central (Hilary Benn) did while he was Secretary of State; he has taken a much more responsible attitude.
