Lord Roborough:

Moved by Lord Roborough

253: Clause 55, page 92, line 29, at end insert— “(9) Where an EDP identifies environmental features that are likely to be negatively affected by any invasive non-native species that is present at the site of the development, Natural England, or a body acting on behalf of Natural England, must take all reasonable steps to eradicate the invasive non-native species that has been identified at the site.”Member's explanatory statementThis Amendment seeks to protect all environmental features identified as at risk by invasive non-native species.

My Lords, in moving my Amendment 253, I will also speak to my other amendments in this group. It is an embarrassment that in our small, wealthy island nation, there are, according to APHA, over 2,000 non-native species, of which 10% to 15% become invasive and pose a serious threat to our biodiversity and environment. We must make intensive efforts to control and eliminate those species to protect our own besieged biodiversity.

The grey squirrel has pushed the red squirrel out of much of our woodlands and now destroys countless young trees every year, making it almost futile to plant native broadleaves in my home county of Devon and many other parts of the UK. What progress is being made with the research into the sterilisation of grey squirrels, and when will that treatment be expected to be made generally available?

Himalayan balsam and Japanese knotweed have invaded our river systems, displacing our native flora and upsetting the ecology for animals and fish living in those waterways. I commend the Tamar invasives group for the work it has done in controlling these invasive plants under the auspices of the Tamar Valley National Landscape in that area. What similar work is being done elsewhere in the country to eradicate these species?

Signal crayfish are present in many waterways and reservoirs, spreading disease that kills our native crayfish and predating on our migratory and freshwater fish species. Muntjac deer are spreading rapidly across our country, feeding on our crops, damaging fences and stripping the bark off young trees. Numbers are out of control.

The purpose of these amendments is twofold. The first is to raise awareness of the damage that these and other species are doing to our environment. The Government need to change attitudes to these animals, birds and plants so that everyone in this country takes steps to eliminate them from their gardens, farms and land.

The second purpose is equally serious. I cannot see how any environmental delivery project funded by this new nature restoration fund can be judged to be successful if non-native invasive species are still present on the land within the project after five years. It simply does not make sense that the EDP can have done an acceptable job on the site if those species remain in place, attacking our much-loved trees, brown squirrels and aquatic species.

Should the Committee support this amendment, I fear there is a risk that Natural England could then choose sites that are not infected with those species. Can the Minister assure the Committee that would not be the case? I think that all who know and love our beautiful countryside appreciate how difficult a task it would be to achieve this even in these limited areas, but it is not impossible, and it is crucial. I look forward to the noble Lord, Lord Cromwell, introducing his own amendments. I beg to move.

My Lords, I start by confirming my support for all three of the amendments in the name of the noble Lord, Amendments 253, 296 and 297. However, I caution the use of “non-native”; it is the invasive aspect that is the problem. What could be more English than a rose? What could be a more typical English fruit than an apple? Both of them originate from central Asia—they are not natives. However, I entirely take the point about invasive species.

Amendment 60, already debated, referred to guidance on planting along highways. There was much discussion about trees and wildflowers. I enjoyed reading what type of tree the noble Lord, Lord Moylan, might represent, which might repay people who want to look it up in Hansard. One plant that grows along our highways which was not mentioned in the earlier debate is ragwort, the bright yellow flowering plant seen everywhere alongside our highway network. Through lack of enforcement of existing legislation, this invasive plant has become a menace to the environment, animals and agriculture, and action to control it is long overdue. Once it has flowered, ragwort produces seeds that, like dandelions which people may be more familiar with, come with a downy parachute which means they float far and wide on the breeze across the countryside and into farmland, where they take root, produce more seed, and so on.

Ragwort is poisonous to livestock, and it is not advisable for people to touch it with their bare hands, although I spend many unhappy hours pulling it up myself with my own bare hands, as I am sure many other Members do. Grazing animals leave it alone while it is growing, but where a field is cut for hay or silage, as is the case on many grassland farms, it gets incorporated into the bales, animals cannot detect it, and they are poisoned by it. Finally, areas set aside for environmental benefits, such as margins for wildflowers, quickly become choked with ever-expanding stands of ragwort.

So much for the biology; what about the law? Ragwort is what is called a notifiable weed, and landowners and occupiers have a legal obligation to control and remove it, particularly if it is spreading, causing a nuisance, or posing a risk to livestock. The Weeds Act 1959 and the subsequent code of practice on how to prevent the spread of ragwort outline these responsibilities. Failure to comply can lead to legal action, and/or the relevant authorities can issue a clearance notice requiring action to be taken to remove it. Unfortunately, this has not been enforced for many years.

As part of my research in tabling this amendment, I asked a Written Question about notices or prosecutions in the last 12 months. I was informed:

“In the past 12 months, no notices in relation to ragwort control have been served to National Highways, and there have been no prosecutions under the Weeds Act 1959 or the Code of Practice”.

I would bet that we could go back a lot more years than the last 12 months and the result would be exactly the same.

That is not good enough. Defra and the Environment Agency need to enforce the existing law and regulations. The Bill will create new areas of land controlled by a quango. This amendment specifically identifies this problem plant and requires that at least in the development of new infrastructure, proper controls are carried out, and—my favourite theme—enforced where necessary. That would be a start.

My Lords, I would like to speak on behalf of the Cinnabar moth, a very handsome creature which is nourished on ragwort. Ragwort is an ordinary part of the downland scene. It is an entirely natural, native plant in its right place. I agree that it can become a pest in some other places, but our downland is grazed by horses. They have the sense not to eat the thing, and we do not make hay out of it.

It is a plant that, in its ordinary place, you can work your way around. It is where someone leaves a field derelict, and it becomes a sea of yellow and the seeds are drifting everywhere, that something needs to be done about it. I agree with the noble Lord, Lord Cromwell, that we should be better, but we should not be too frightened of ragwort. It is not hugely disastrous for agriculture or livestock, in my experience of it.

I invite the noble Lord to spend a series of weekends with me and my family pulling up ragwort across the organic grassland, which we bale for organic dairy farmers. After that, he may consider that ragwort is fine in his backyard but that, for those who are trying to feed the nation, it is a serious problem. Our livestock do leave it alone—he is quite right that they have the good sense to eat around it—but once it is baled and dead, they eat it.

The prospect of spending weekends with the noble Lord, Lord Cromwell, seems well worth some ragwort pulling.

I also sound a note of caution in respect of the amendments tabled by my noble friend Lord Roborough, as they are drafted, particularly Amendment 296. Animals such as the grey squirrel and the muntjac come and go as they please; you cannot eradicate them from an area. You can try pushing them back, but we are stuck with them until we develop a national solution. You should not penalise an EDP because it happens to be infected by them.

Also, are we referring to the list that is generated by retained EU regulation 1143/2014 when we are referring to invasive non-native species? This list consists mostly of things that are troublesome in much warmer climates. A lot of things that cause problems for us, such as sycamore, would not be included at all.

I am cautious. It is hard to eliminate invasive species from waterways. Unless you control the whole waterway and have a really integrated, careful and expensive campaign over several years, it is very difficult to do more than just reduce. By and large, we should learn to live with these invaders. I say this as a lifelong botanist. We have; we enjoy and celebrate the thousands of plants which have come to live here, mostly courtesy of gardeners, and which play a small part in the native flora.

There are very few plants that cause a huge problem in terms of invasiveness. Animals can be difficult. Insects are difficult but really hard to control. Anyway, when it comes to the flora of this country, we should recognise what we mean by “native”. If we go back to the ice ages, you are talking just about birch and a bit of Scots pine. The ice ages crushed the European temperate flora against the Alps. As a result, we have a really depleted flora in Europe compared with China or North America, which both had southern refuges that their flora could get to. You really see that in the case of forestry; we have 30 woody species in this country. Every year or two, a disease threatens another of them. I am starting to lose my mature oak trees to acute oak decline, having lost a lot of ash and all the elm.

A healthy temperate woodland has hundreds of species in it. That a few are finding their way back from gardens, diversifying and getting us back to a level of diversity that we ought to have is to be celebrated. Instead of this fuss about what is non-native, let us celebrate the immigrants. Surely the party opposite agrees with that.

Without referring back as far as the ice age or taking as long as that to talk about it, my Amendment relates specifically to one plant. Is the noble Lord suggesting that we do not apply the existing legislation? That is what my amendment seeks—merely to apply the law as it stands now through enforcement, not to create new law.

My Lords, where it is troubling serious agriculture, yes, we should enforce.

My Lords, on the grounds of “it takes one to know one”, it is worth noting that this is a debate that we are unlikely to have in the next Session of Parliament—old-style hereditary Peers’ contribution to the governance of this country.

I will talk briefly about invasive species. I declare an interest as a landowner in Cumbria. It has always seemed to me that the real problem in dealing with the ones that are pests, of which we can all think of a number—Himalayan balsam, Japanese knotweed and so on—is that those of us who want to see them rolled back have never managed to capture the hearts and minds of the country. It is no good just doing it yourself, as I think the noble Lord, Lord Lucas, said. I suggest to the Government that they should think in terms of trying to enrol the nation on this particular crusade.

I say this because my contributions towards our local red squirrel group may be endangered, although I hope they will not be, by reduction in support for my agricultural enterprises, because there is less money going round. There might be ways of incentivising those involved in land management, possibly with a little financial contribution as part of a wider package, to make some of these things happen. I will leave it at that, other than to say that if anybody wants to see an extreme example of a reservoir with a whole group of invasive species in one place, they should travel by train from Preston to Manchester and look out the window. They all seem to be there on the verge of the railway line.

On a lighter note, the noble Lord introduced the issue of hereditaries; many of us are indeed invasive species as we came over with the Normans.

I say to the noble Lord, Lord Lucas: does he want to accept these invasive plants? What about Japanese knotweed, which is in the schedule of wildflowers and illegal to perpetuate? Once it takes root, it is very difficult to get rid of. If it is cut, tiny things will spread. Is he still in favour of Japanese knotweed?

My Lords, I have managed to eliminate Japanese knotweed successfully several times. It requires a bit of time and a bit of glyphosate.

I have also got rid of Japanese knotweed—I have not had much success with Himalayan balsam, though.

I thank the noble Lord, Lord Roborough, for Amendments 253, 296 and 297, and the noble Lord, Lord Cromwell, for Amendment 253B. I will consider these together because they all relate to invasive non-native species and the nature restoration fund. The Government recognise the impacts of invasive non-native species on our native species and ecosystems. As the Minister for invasive non-native species, I appreciate the noble Lords’ intentions in tabling these amendments, but they do not align with the targeted nature of the nature restoration fund.

However, I reassure noble Lords that I have a particular bee in my bonnet about how we best tackle invasive non-native species, because they can have a devastating impact on our native biodiversity. Himalayan balsam means that nothing grows at all, and it wrecks riverbanks. However, it is about not only what is here at the moment and how we manage it but how we stop more invasive species coming in. That is a huge challenge. While I am on that subject, the noble Lord, Lord Lucas, asked about the list—it is retained EU law, but we have been reviewing and amending it in order to tailor it to UK circumstances.

Amendment 253 would require Natural England to take action to eradicate the invasive non-native species that could negatively impact an EDP’s environmental features. The legislation already allows invasive non-native species control to act as a conservation measure, where this would support the action of Natural England to materially outweigh the impact of development on the relevant environmental feature. However, we should recognise that it might not always be the best option in terms of environmental impact, value for money and delivery considerations, such as the need to secure the overall improvement by the EDP end date.

Requiring action to eradicate invasive non-native species, regardless of these considerations, could delay EDPs, increase costs, and limit the ability to secure positive environmental outcomes. With these amendments, the Secretary of State would be required to revoke an EDP—even one delivering effectively for nature—because of the presence of a single grey squirrel, which does not make sense in the bigger picture. Making EDPs contingent on mandatory eradication in this way could also make them unviable. On the grey squirrel question, the noble Lord asked about the sterilisation programme. To confirm, the programme is ongoing, and is being supported by Defra.

Amendment 253B, tabled by the noble Lord, Lord Cromwell, seeks to require bodies exercising powers relating to an EDP to ensure that legal obligations under the Weeds Act 1959 are “publicised, observed and enforced”. The Weeds Act grants powers for the Defra Secretary of State to serve landowners with a requirement to remove the weeds specified within the Act, and ensures that landowners retain responsibility for their own land, instead of public bodies needing to act.

EDPs are a targeted tool to address the impact of development on specific environmental features. Introducing a broad obligation for Natural England, and others exercising responsibilities relating to EDPs, would expand the scope of EDPs, and risk diverting focus from their core purpose. The noble Lord, Lord Cromwell, and others discussed ragwort. I assure the noble Lord that there is nothing in this legislation that would preclude Natural England or others from taking action in line with the Weeds Act, such as reporting the presence of ragwort where this is encountered, or from appropriately removing such weeds where Natural England, or delivery partners, are delivering conservation measures on the ground. With these explanations, I hope that the noble Lord, Lord Roborough, will withdraw his amendment.

My Lords, I was interested in that debate, and would like to pick up what the Minister said. Given her responsibilities, could she update us on the point my noble friend Lord Roborough made about the grey squirrel? Could she be a little more specific about the up-to-date situation on that, but also on deer in general, which are causing havoc to young plantations and farmland? Those might not include non-native or invasive species, but there are far too many deer in the countryside.

One of the main deer that cause a problem is non-native, but we will not go into that. The department is currently producing the revised deer strategy, which I am sure we can share with the noble Earl when it is produced. The noble Earl, Lord Kinnoull, is working closely with the group working on the grey squirrel sterilisation programme. I have had meetings with him and his colleagues, but I cannot provide the details of that, as it is something that they are driving forward themselves. It may be worth the noble Earl having a conversation with the noble Earl, Lord Kinnoull, and we are supporting the work that he and his group are doing.

My Lords, I am grateful to all noble Lords who contributed to this short debate, and particularly to the Minister for her knowledgeable answer. I add my thanks to the Minister for a meeting which she organised a couple of weeks ago with her officials. The depth of knowledge of those officials on this subject was phenomenal.

The noble Lord, Lord Inglewood, made a good point about public education. These are not adorable, furry animals, these are pests. They are causing damage to our wildlife, our trees, and to everything in our country, and people need to be aware of that. I could not agree more with the noble Lord, Lord Cromwell, about ragwort. My experience is that responsible farmers remove this as soon as they see it, and it is disappointing to see public bodies not taking that responsibility seriously.

I also thank my noble friend Lord Lucas for his points. He slightly contradicted himself; of course, it is very difficult to remove these invasive non-native species, but the point is that it is not impossible. I had the same experience with Japanese knotweed and Himalayan balsam; you can eradicate them, but you have to work at it.

I will take away the comments made in the debate, and perhaps see whether there is something we can do, in this Bill or elsewhere, to try to strengthen the defences against these. I withdraw my Amendment.

Amendment 253 withdrawn.

Amendment 253A not moved.
