National Pollinator Strategy

Debate between Sarah Wollaston and David Heath

Thursday 16th October 2014 Commons Chamber

[Mr David Heath (Somerton and Frome) (LD)]

I am delighted that the hon. Member for Truro and Falmouth (Sarah Newton) secured this debate, to which I am a co-signatory. This is an opportune moment to talk again about the national pollinator strategy and what we do in this country about pollinators, and to pick up on the issues that are still to be resolved in the development of the strategy.

I make no secret of the fact that I have been interested in this subject for a long time. I asked questions in the House eight or nine years ago about what the then Government proposed to do about bee health. They did nothing for some time, but then they did do something. I give them credit for putting money into research towards the end of their period in office.

This country can be very proud of the National Bee Unit and the work that it does. I am delighted by its work, because it underpins some of our efforts. Having said that, although I was not the Minister responsible for bee health when I was in the Department for Environment, Food and Rural Affairs—that responsibility was held by my noble Friend Lord de Mauley—I looked closely at the information that was presented and was conscious of the huge gaps in our research base on this subject. That is the case not just in relation to the domestic honey bee, as it were, on which we at least have a large body of observation data from beekeepers, who know what their charges are doing, but particularly in relation to wild bees, such as the bumblebee or Bombus species, and other wild pollinators. We do not know how they integrate with the environment, what contribution they make or the state of their population health. Unless we have base figures, we have no understanding of what is happening.

What we do know is that the health of pollinators and the strength of the population are affected by a large number of factors. I suspect that climate is the biggest factor, but it is certainly not the only one. I suspect that weather played a big part in the recovery of some bee populations this year. Simply by observation, I have noticed that the bumblebee population in my garden has been substantially better this year than in previous years. There are also various diseases and infestations. The varroa mite is still a significant problem and there are many other conditions of which we need to be aware.

A major factor is whether there are sufficient suitable habitats for pollinators. That is not helped by intensive agriculture. The more effective crop management we have, the more we need other land to be available for pollinators. We must provide that balance. I am not against good crop yields—they are essential if we are to feed ourselves—but if they are to be sustainable, we need other elements to be in place. That might mean sacrificing land to provide pollinator habitats. Another factor, which the hon. Member for Southampton, Test (Dr Whitehead) spoke about, is the effect of various pesticides and other dressings on crops. I will return to that in a moment.

We have a lot to celebrate. I am pleased to have pushed hard for a national pollinator strategy, because it is so important. I congratulate my colleagues in the Department for pushing it forward and look forward to the day when it is finally in place. There are a number of factors that I would like the Minister to consider.

The first factor is research. We need to commission research in the right places. We must carry out research in combination with those overseas who are looking at the same issue, although perhaps in slightly different habitats, in order to understand what is going on. The key is to have a base figure for populations from which we can extrapolate future population health. We need to consider issues that relate to specific species. We need a strong scientific base in order to do that. The Department must therefore have the ability to commission research or to ensure that others do so. It might be done at the European level or elsewhere, but let us make sure that it happens.

The second factor is the recruitment of the army of citizen scientists into the process. We saw how effective that was when dealing with ash dieback last year, and how useful it was to have people who would go out and look at what was happening. It is interesting that ash dieback has now been carried by the wind to north-west England, yet not a single newspaper or parliamentarian has a word to say about that, although it was the biggest crisis ever only a year ago. However, that information helped us to provide the best response we could, even if it was incomplete—again because of the lack of knowledge —so we must use that.

The third area—this is probably the biggest point I want to leave with the Minister—is that the Government’s one major lever to improve the health of our pollinator population is to use pillar two of the common agricultural policy in an effective way to give positive encouragement to land that ought to be available for pollinators, and to the sort of growth on land that would encourage them. I have still not seen the final outcome, but when I was Agriculture Minister I pressed hard for the key element of pillar two in the future to be direct support for pollinators and to ensure that good behaviour is rewarded. We need to see headlands and land that is not available for main crops being used effectively, and the so-called ecological focus areas should provide a useful addition to the ecology of an area, rather than being rather arbitrary and token.

[Dr Sarah Wollaston (Totnes) (Con)]

At the moment, taking advice on which 5% of land should be an ecological focus area is voluntary. Does the hon. Gentleman agree that there should be slightly firmer guidance about which areas could be used as ecological focus areas, so that we get the best from them?

[Mr Heath]

I am genuinely in two minds about that. I agree that the advice must be there, and that farm and wildlife advisory groups are probably the best apparatus for doing that, along with Natural England and other agencies. However, when I was a Minister, I visited Dartmoor—not a million miles from the hon. Lady’s constituency—and spoke to farmers there. They took a different view on how they used what were then the high-level stewardship schemes, and had a less prescriptive approach. They spoke more about outcomes and what they were trying to achieve, and they let farmers use their own land skills to achieve those outcomes. That was successful, and made me think that perhaps we are sometimes too prescriptive, rather than under-prescriptive, in what we do. Yes, we need advice, but I think we sometimes underestimate the ability and willingness of good farmers to do the right thing for their local environment. They would like to do that if they are given the encouragement and scope, so let us see what we can do in terms of design.

Mention was made earlier—I think it was the hon. Member for Richmond Park (Zac Goldsmith)—of the importance of other Departments playing their part. DEFRA cannot do this on its own, and I would like local authorities to be much more attuned to what they can do to encourage pollinators, even if that is only ensuring that the local park contains pollinator-friendly plants, as that would make a difference.

I will conclude with perhaps the most contentious issue: pesticides. Pesticides are a hazard to insects—that is obvious; they would not be pesticides if they were not. The difficult question that the Government, chemical companies and agriculturalists have to answer all the time is whether that hazard, along with the level of exposure, is a real risk to the pollinator population. That was the difficulty we had with neonicotinoids: there was no evidence to suggest that the hazard that undoubtedly existed and could be demonstrated in sub-lethal quantities in a test tube or laboratory, represented a risk in field conditions, because no work had been done on that. I hope that work has now been done to substantiate that properly one way or another, because such a lacuna in information is unsupportable when it comes to making a competent and coherent decision. The other risk is that banning neonicotinoids encourages the use of pyrethroids and organophosphates, which we certainly do not want to promote, as they are significantly worse options not just for pollinators but for every other living creature in the vicinity.

Before I sit down I will just mention one point. Hon. Members may not know that next year we have the Milan Expo. The UK’s contribution will be based on the life of the honey bee. I am very proud that our Government and our country recognise the importance of the honey bee, so much so that that is our window to the world.

Ash Dieback Disease

Debate between Sarah Wollaston and David Heath

Monday 29th October 2012 Commons Chamber

[Mr Heath]

We will continue the programme of inspection that has identified those saplings that may be a risk and destroyed them. The ban has been in place on a voluntary basis—it is now on a statutory basis—to ensure that nothing came into the country over this summer and therefore was not available for the next planting season. We can be reasonably assured that infected trees will not be planted this winter—at least those from commercial sources—but we need to maintain vigilance, which we certainly will do. We will also work closely with the industry, which understands how dangerous the disease is and wants to co-operate. I am grateful for the help it has given to the Department in identifying and dealing with the threat at an early stage.

[Dr Sarah Wollaston (Totnes) (Con)]

We have already seen one dangerous tree disease spreading into other species—phytophthora. Is there any evidence of Chalara spreading into other species, either on the continent or here?

[Mr Heath]

I do not believe that there is evidence of Chalara crossing species at the moment, but I will check that and give the hon. Lady an accurate response. She is right about phytophthora, which is well evidenced. In the case of Chalara fraxinea, we are dealing with a specific issue for the ash tree but, as she will be aware, fungal diseases are sometimes more easily spread between species than some other pathogens. I will examine all the evidence and write to her if there is any suggestion of cross-species spread.
