Bee Population

Lord De Mauley Excerpts

Thursday 10th January 2013 Lords Chamber

[The Parliamentary Under-Secretary of State, Department for Environment, Food and Rural Affairs (Lord De Mauley)]

My Lords, I thank my noble friend Lord Moynihan for initiating this debate and for giving me this opportunity to highlight what the Government have been and are doing to improve honeybee health and to outline our future plans for this important area. I would like to thank all noble Lords for their fascinating contributions. They have almost talked me into developing a healthy conflict of interest.

Honeybees are extremely important for pollination, yet, as almost every noble Lord who has spoken has said, they are facing a growing number of threats from pests and diseases that pose a significant challenge to beekeepers. Noble Lords will also be aware of the very poor summer we experienced in 2012 and the effects that this had on agriculture and the environment. Last year was described as the most difficult beekeeping year ever, even by experienced beekeepers, and the annual honey crop is estimated to be down—as I think my noble friend Lord Moynihan said—by more than 70% compared with 2011. Therefore, we are taking this very seriously and are taking action to improve honeybee health and support beekeeping for the future.

Let me first explain the work we have already got under way. The main focus of our efforts in protecting bee health is through the work of the National Bee Unit, which is acknowledged as having one of the best bee health surveillance programmes in Europe, with a global reputation for excellence. The first of the unit’s main activities is inspection and enforcement. We have a team of professional bee inspectors out in the field, about which my noble friend Lord Patten asked and to which I will return, controlling notifiable diseases and surveying for exotic pests. I am pleased to report that, because of their work, we are able to say that the incidence of the two notifiable diseases—European and American foulbrood—remains low, with infection rates around half of those observed during the 1990s. Most importantly, no evidence of exotic pests, such as the small hive beetle, has been found and fortunately these pests remain absent from the UK.

Secondly, the unit provides advice to beekeepers, which was particularly important in view of the very poor summer weather, and specific advice was published to help beekeepers during this period. Thirdly, among the unit’s main activities is research development, such as developing control methods for small hive beetle. Fourthly, it contributes to evidence-based policy development, including quantifying risks to bee health from current and emerging threats, diagnostic services for pests and diseases, and contingency planning against the arrival of exotic pests and diseases.

Fifthly, the unit helps beekeepers to become more self-reliant in controlling pests and diseases through training and education programmes jointly run with beekeeping associations. The National Bee Unit was involved in nearly 500 training events last year, which were attended by more than 22,000 beekeepers. Feedback from those attending has shown that beekeepers have valued and benefitted from these events.

The Healthy Bees Plan, which has now been under way for more than three years, was initiated by the previous Government and has been enthusiastically pursued by this Government. Let me set out what has been achieved so far and our plans for the future. A first priority of the plan was to get a more accurate picture of the numbers and distribution of beekeepers and the health of their colonies. Between 2009 and 2011, the NBU visited and took samples from around 5,000 apiaries in England and Wales, which was one of the biggest surveys of its kind ever undertaken.

As the results on the health of our bees became available, we began a review of our pest and disease control policies. This was undertaken by the Food and Environment Research Agency, the Welsh Government, the NBU, representatives from beekeeping associations and an independent scientist. The review considered how best to manage pests and diseases in the future to ensure that effective policies and support are in place; that priorities for future collective action by government and beekeepers are clear; and that we are making the best use of public funding. I should like to take this opportunity to announce to your Lordships that today we are launching a consultation seeking views on the proposals which emerged from this review. These proposals build on current policies and, importantly, set the future direction for pest and disease control.

The second priority of the Healthy Bees Plan was to improve beekeeper training, about which several noble Lords have asked. We have co-funded initiatives with beekeeping associations, of which an example is 400 new beekeeper trainers and a suite of new training materials and courses. These jointly funded programmes will continue during the next phase of the plan to 2015. One of these programmes is the development of an apprenticeship scheme to be launched shortly to encourage young people to become bee farmers and we are working with the Bee Farmers’ Association to take this initiative forward.

The third priority of the plan was to increase the number of beekeepers registered on the NBU’s BeeBase database. BeeBase is an important tool in the control of bee diseases and pests, and the chances of successful control are significantly improved if the location and contact details of beekeepers and their apiaries are known. I am pleased to report that the number registered has increased from around 18,000 when the plan was launched to nearly 29,000 now, which is a tremendous achievement.

We are also working to improve the availability of medicines for the treatment of bee diseases and have developed an action plan involving manufacturers, beekeepers and bee inspectors. Details of bee medicines which veterinarians can import from other member states are available on the Veterinary Medicines Directorate’s website.

Turning to the ongoing issue of the effect of neonicotinoid pesticides on bees, which my noble friend Lord Moynihan mentioned, as did several other noble Lords, perhaps I may stress to your Lordships that I take very seriously any threat to bees and other pollinators. We have kept evidence on neonicotinoids under close and open-minded scrutiny and will restrict the use of these products if the evidence shows the need.

Government scientists and the independent Advisory Committee on Pesticides advise that, while the potential for toxic effects has been shown, the evidence currently available does not indicate harmful exposure in the field. Nevertheless, my noble friend Lady Thomas referred to the fact that we are working rapidly to fill crucial knowledge gaps. We have research under way which is nearly finished to look at field effects of neonicotinoids on bumble bees. We are studying historic data on bee health and neonicotinoid usage. We are analysing the implications of possible restrictions for the environment and for agriculture. These work streams will deliver very soon. We will consider the results and the action required as a matter of urgency.

I turn now to research funding, about which several noble Lords have asked. We have joined some of the UK’s major research funders to tackle the decline in insect pollinators. Understanding the causes of this decline will help us to identify the best possible action to support and sustain these species for the future. This is important given the role of pollinators in local food production and in our overall food security. The initiative’s total spend is up to £10 million over five years. Nine projects were announced in June 2010 that will look at different aspects of the decline of insect pollinators and bring together researchers from many disciplines, including ecology, molecular biology, mathematics and computing. Some will focus on specific species and/or diseases; others will look broadly at factors affecting the health and survival of pollinating insects more generally. Two of these projects focus specifically on honeybees and six will benefit both honeybees and bumblebees. We look forward to seeing the results of these studies over the next two years.

My noble friends Lord Moynihan and Lord Hodgson asked about progress on developing a bee strain resistant to Varroa. Many attempts have been made both in this country and worldwide to breed Varroa-resistant or Varroa-tolerant bees. This includes work carried out at the University of Sussex since 2008. I understand that, despite anecdotal evidence to the contrary, this has so far been unsuccessful. This is in part due to the genetics of honeybees. Other novel molecular approaches are currently being developed for the control of Varroa. The recent sequencing of the genomes of Apis mellifera and Varroa destructor could aid the identification of tolerant strains in the future by targeting relevant genes and traits more effectively.

My noble friend Lord Moynihan, among others, stressed the importance of education. A key priority of the Healthy Bees Plan is to deliver an enhanced training and education programme for beekeepers, driving up husbandry standards and the management of pests and diseases. Defra has so far co-funded education and training initiatives with beekeeping associations and I referred to that a little earlier.

My noble friend Lady Thomas asked whether neonicotinoids were used by local authorities on verges and, indeed, in private gardens. Agriculture and horticulture is by far the largest market; although they are also authorised for use in other situations including, for instance, use on high-quality turf on golf courses. They are unlikely to be used by councils on roadside verges where herbicides are more likely to be used. They are authorised for amateur use in private gardens but these products are authorised at much lower doses than are allowed in professional applications and are used on a much smaller area. Furthermore, they are only authorised if they can be used without harmful effects on human health or unacceptable risks to the environment. No product is authorised for home or garden use if its correct use requires training or protective equipment.

My noble friend Lady Byford asked about the results of the IPI—the Insect Pollinators Initiative. I can tell her that all projects within it are progressing well and we look forward to seeing the results in 2014. She also asked whether research has been carried out into the nature and variety of diseases affecting plants and trees and whether there is any evidence that diseased plants or trees are for some reason more attractive to insects. In fact, a considerable amount of work has been carried out by Defra, Fera, Forest Research, universities and research institutes into the nature and variety of diseases affecting plants and trees. That may be, perhaps, a subject for further debate. However, specifically in respect of whether diseased plants or trees are more attractive to insects, it is true that certain studies have indicated that this can sometimes be the case. For example, a recent paper shows that a plant pathogen can make the host more attractive to insect vectors and there is, of course, a risk that they further spread the pathogen.

A paper published in 2005 suggested that the pathogen causing Dutch Elm disease makes host trees attractive to insect vectors. However, a recent Dutch paper showed that white clover mosaic virus infection can decrease the attractiveness of white clover plants for female fungus gnats. I hope that my noble friend is aware of the expert task force set up by Defra’s chief scientist specifically to see what can be done to enable us to be on the front foot in anticipating plant diseases from abroad that pose a potential risk to us. The interim report of that expert task force is very welcome.

My noble friend Lady Thomas and the noble Lord, Lord Rea, spoke about restrictions on neonics in other countries. There were several incidents in May 2008 in which these pesticides killed bees in Germany. As a result, the circumstances in which they can be used have been restricted in Germany although the products have not been banned. According to the German authorities, the incidents resulted from the inadvertent exposure of bees to one of the neonic products applied as a seed treatment to maize seed. We have assessed the risk of the German situation being replicated here as negligible for a variety of reasons. Three other EU member states, France, Slovenia and Italy, have introduced some restrictions although all have neonic products authorised. Slovenia took action following incidents similar to those in Germany. Italy has restricted the use of these pesticides in the wake of the German incident as a precautionary measure and in France Imidacloprid has been suspended for seed treatments on sunflowers since 1999, and on maize since 2004. The basis for the recent French action is not entirely clear. They cited a review by the French agency ANSES. However, ANSES did not in fact call for a ban and its review does not appear to support one. The UK is therefore in step with most other EU countries and, most importantly, we are acting in accordance with the evidence.

The noble Lord, Lord Rea, asked whether we agree with the use of the precautionary principle. We fully accept that the precautionary principle is applicable in considering the appropriate response to the potential effects of pesticides. The principle guides decision-making when a serious potential risk has been identified and where, following the best possible risk assessment, there remains scientific uncertainty. It does not dictate the appropriate decision.

My noble friend Lord Patten asked about bee inspectors. I assure him that they exist. I have met them, or many of them, on a course on my visit to Fera in Yorkshire. There are about 60 National Bee Unit inspectors. They are an extremely important component of the bee health programme and they are gearing up for another busy year. I can tell my noble friend that, far from reducing, their numbers have increased since the 2009 launch of the Healthy Bees Plan. He asked whether the inspectors have a uniform. It is grey and has the Fera logo on it.

My noble friend also asked about the quality of science obtained by Her Majesty’s Government and our European partners for any decisions on pesticides. The Government have made clear their determination to act on the evidence. We have therefore commissioned a number of research projects to fill gaps in what is known. These include, among a number of other projects, a study of real exposure of bumblebees in the field to oilseed rape treated with neonics and a study of the significance of pesticide residues in disease levels in healthy honeybees. This work is being taken forward as rapidly as possible and is nearly ready for consideration by the independent experts of the Advisory Committee on Pesticides. In Europe, the focus is on using the new science to update the standard process for assessing the risks of pesticides to bees, and UK experts are actively involved. My noble friend referred to the need to improve pesticide management and hygiene. I absolutely agree with that. That is a key aspect of the consultation we are launching today.

My noble friend Lord Jones of Cheltenham asked what assessment the Government have made of the effect of the loss of habitat on bee populations. In 2011, the UK National Ecosystem Assessment concluded that since 1980 wild bee diversity has declined in most landscapes. It identified land use change and habitat loss as key drivers of the decline in wild bees as well as other pollinating insects alongside disease and the use of some pesticides. We have lost 97% of our flower-rich grasslands since the 1930s. This is why the focus of our conservation effort for pollinators is the protection and management of habitats through protected site policy, agri-environment schemes and new initiatives such as nature improvement areas.

He asked whether the Government would consider protecting meadows in any future planning legislation, and the noble Lord, Lord Stevenson, raised questions in that area as well. Protection for meadows is in place. Flower-rich grasslands, including lowland and upland meadows, are already recognised in the list of habitats of principal importance for the conservation of biological diversity in England, published by the Secretary of State, under Section 41 of the NERC Act 2006. The National Planning Policy Framework, published in 2012 requires planning authorities to promote the preservation, restoration and recreation of priority habitats, ecological networks and the protection and recovery of priority species populations. The Environmental Impact Assessment (Agriculture) (England) (No. 2) Regulations 2006 protect uncultivated or semi-natural areas, such as hay meadows from being damaged by agricultural work, such as planning, draining and use of fertilisers and herbicides where the uncultivated land or semi-natural areas directly affected are two hectares or more in area. I could go on, but I am conscious of the time. Perhaps I might suggest that a detailed debate on the Bill, to which my noble friend referred, could be conducted when it comes before your Lordships’ House.

My noble friend Lord Jones asked whether the Government agree with Buglife. While important, honeybees are only a small part of the insects which pollinate crops. Of course, we agree. Recently published research from Reading University suggested that managed honeybees were responsible for about a third of pollination in the UK, noting that this was after a decline in managed bee populations. The national ecosystem assessment suggested that wild pollinators contribute a significant proportion of that total. My noble friend also asked what the Government were doing to conserve wild bees and other pollinators. Perhaps I will write to him on that because I have covered it a little already and can expand on it. He asked whether the Government will invite responses from Buglife and other organisations to the consultation. The Government would welcome responses from any individual or organisation with an interest in protecting our bees.

My noble friend Lord Hodgson asked who is in charge. Well, my Lords, I am. I am the Minister responsible for bees. To be slightly less glib, Defra has the co-ordination role and collaborates closely with the Welsh and Scottish Governments who also fund Fera in part. I will write to noble Lords—the noble Lord, Lord Stevenson, invited me to do so. I think that I have rather good answers to some of his questions but I have simply run out of time. There are continuing challenges for bee health that need to be addressed and there are no signs that these are likely to diminish. Although the number of colony losses noted by the National Bee Unit inspection during the beekeeping season has fallen from 12.5% in 2008 to 5% in 2012, the poor summer weather could see this trend reversed, so the challenge continues. I assure noble Lords that the Government are committed to continue to play their part in working with beekeepers to sustain the health of honeybees. Our successes in recent years provide a clear platform for determining the priority actions necessary to achieve that important goal.
