Environment Bill

Debate between Lord Curry of Kirkharle and Lord Blencathra

Committee stage
Monday 12th July 2021 Lords Chamber

[Lord Curry of Kirkharle (CB) [V]]

My Lords, it is a pleasure to follow the noble Viscount, Lord Trenchard. I wish to speak to Amendments 259 and 260 in the name of the noble Baroness, Lady Young of Old Scone, and to comment on Amendment 260A in the name of my noble friend Lord Kinnoull. I once again state my interests, as far as this debate is concerned, as a trustee of Clinton Devon Estates and chair of the Cawood group.

Much comment has already been made in this debate about tree health, including the deep concern about biosecurity and tree diseases and the need for a tree strategy. Given the Government’s ambition to plant 30,000 hectares of trees each year to improve tree cover and for climate change mitigation, and with the perilous state of tree health in Britain, the need for a tree strategy is undeniable. As has been said already, it was a tragedy when we lost our elm trees to Dutch elm disease; what a lovely tree the elm is. Our ash trees are now at risk from ash dieback, not to mention our larch. We have in our garden an ash tree that will have to be felled soon because it is infected. A recent forecast predicted that more than 90% of ash trees will be taken out by ash dieback. Most of our fence lines—our field divisions—in Northumberland are populated by ash trees; it is the most dominant species. Many are mapped as part of stewardship audits and are the homes of little owls, for example, and many other species, so their disappearance will be a disaster both visually and environmentally, as the noble Lord, Lord Teverson, mentioned.

Biosecurity is so important. We must reduce our dependence on imported tree stock. As the noble Viscount, Lord Trenchard, said, this does not mean that we need to ban imported trees completely, but a biosecurity plan would be able to identify the tree species that we could safely import. Outside the European Union, we can grow our own and in doing so support the rural economy. The Government should see this as yet another important opportunity.

The tree strategy should not only include our ambition to plant trees but incorporate the appropriate biosecurity measures and guidance on a species mix to minimise disease spread. I spent some time early last year in New Zealand, where large numbers of farms are being purchased and planted as part of a carbon offsetting scheme by global corporates. A lot of the planting has been indiscriminate, without due regard to soil type or carbon sequestration potential and without assessing the risk of disease. We must not make these mistakes. Identification of land quality in areas suitable for growing a specific mix of tree species to optimise long-term carbon sequestration is essential. To plant vast areas of land with tree cover—30,000 hectares a year, for example—to ease our climate change conscience and potentially become part of the carbon market without clear guidance on tree species and topography would be hugely irresponsible.

This strategy would help to reduce this risk and hopefully maximise the benefits: economic benefits; environmental benefits in terms of both carbon and biodiversity; and, importantly, public access benefits. The adequate protection of trees from a variety of predators is of course also essential, as suggested in Amendment 260A, and could be part of a tree strategy. I encourage the Minister to think about this very seriously indeed.

[Lord Blencathra (Con)]

My Lords, I declare my interests as in the register. I rise to commend the statements by the noble Baroness, Lady Young of Old Scone, and her excellent moving of the amendments. She set out the case admirably. I also agree with what was said by the noble Earl, Lord Kinnoull, and just now by the noble Lord, Lord Curry of Kirkharle.

I strongly believe that ancient woodlands must be protected where possible since they cannot be created except through a process that takes 400 to 500 years. This means that all developments that would remove them or parts of them or damage them must be avoided, and only in very exceptional circumstances should an ancient woodland be harmed. There should be a presumption against all developments affecting them.

The suggestion by the noble Baroness, Lady Young of Old Scone, in Amendment 258 is ingenious and I have some sympathy with it. However, I am not certain that classifying every ancient woodland site—I think she mentioned 1,200 of them—that has been wooded since 1600 AD as an SSSI automatically is the right answer. As I understand it—I think the noble Viscount, Lord Trenchard, made this point—there is nothing to prevent any woodland being classified as an SSSI right now if it meets the current criteria. I would prefer to see ancient woodlands assessed individually and, if suitable, declared—each one on its merits—an SSSI. I must also say to the noble Baroness that I do not think that it is legally possible to mass nominate dozens or even hundreds of pieces of land and to do it en masse, whatever features are on them.

As someone on the board of Natural England who has to decide on new SSSIs or extensions to them, I can tell the House that it is an incredibly detailed and exacting procedure. Officials must produce reams and reams of scientific justification and strict legal protocols must be followed, with all affected landowners entitled to make representations and appeals. If over that two or three-year process we put one foot wrong, we are straight into judicial review territory, which I should say has never happened yet. There might be an argument for simplifying the procedure—we certainly need to do that in the case of declaring new national parks or AONBs—but, for the moment, we have to follow the current law. Thus, while the noble Baroness’s amendment is ingenious, it will not stand up.

On Amendment 259, I am 100% behind her. This is not a “little Englander” new clause. For tens of thousands of years, our native fauna have survived and developed in a habitat of native British flora. Putting it simply, we cannot have red squirrels unless we have the native woods producing the nuts, fruits and seeds they normally eat. The Back from the Brink project to recover 20 species from near extinction depends on native habitats. As colleagues will know, we face an increasing threat from diseases unwittingly imported along with plants sourced from abroad. Even if we step up biosecurity now that we have left the EU, there will still be an enormous risk of bringing in destructive bugs and diseases. Nearly every single disease or bug that has destroyed our UK trees has been imported. If Xylella fastidiosa—the most dangerous and lethal plant disease in the world—gets here, God help us. It can kill 595 different plant species in 85 different botanical families. Our countryside and all our gardens would become wastelands.

No matter how good port control might be, even if it is beefed up from the current inadequate levels, we cannot stop bugs and diseases coming in. Contractors will want to source the millions of trees and bushes needed for HS2 or Highways England road schemes from the cheapest suppliers. At the moment, they are the huge Dutch growers; that is where diseases will come in. This is why a requirement on acquiring plants from UK sources is so important. As the noble Baroness, Lady Young, said, it will also be good business for UK nurseries, which can easily supply all that would be required in due course.

We have a huge range of UK native trees, and there is no excuse not to use them: noble Lords need only look at the Woodland Trust website to see the range of native species and all the animal, bird, butterfly and other species that depend on our native flora for survival.

Finally, I want to support Amendment 260A. We will never achieve a fraction of the new woodlands that we wish to create unless we deal with rabbits, which are no longer much of a problem, and grey squirrels and deer, which are. One day in 1990, the then Minister of Agriculture, John Gummer MP, asked me, as junior Minister, to go through the MAFF research budget and root any unnecessary or wasteful research. Among others, I found a £250,000 programme researching the effect of rabbits on new woodlands schemes, which the department was funding. There was also one on controlling rabbits, which had been on the go since the 1940s, and another that was also running at £250,000 per annum and was on something that I cannot recall. I called in officials and said, “Have you found that rabbits are eating the bark of new saplings and killing them?” They looked surprised and asked if I had seen the report’s preliminary findings. Remaining remarkably calm for me in the circumstances, I pointed out that I was a countryman and did not need to spend £250,000 to discover that rabbits eat the bark of young trees.

When I spoke to officials on rabbit control, they informed me that there had been a marvellous breakthrough in that contraceptive pills were now 100% effective if eaten by the rabbits—but they could not find any way to make the rabbits eat them. I said that we did not need to spend another £250,000 researching the effects of ferrets and shotguns on rabbit populations, which had been proven to work in the past. But the problem was—and I think still is—that the department, understandably, was looking for huggy, squeezy, nice ways to control rabbits, and we have the same attitudes today dealing with grey squirrels, the destructive American tree rats. I recommend that the Minister have a word with the noble Lord, Lord Redesdale, who ran a highly successful programme to deal with grey squirrels in Northumberland. With proper funding, that should be replicated throughout the country.

We also need to eliminate the Chinese muntjac deer. They are not a native species, either, and the damage they do to our native flora is immense. I quoted that story about rabbits, but rabbits are not the main problem now: squirrels and deer are. The point is that for over 40 or 50 years we have been researching how to deal with rabbits and have not got the solution. I wonder how many years we have been researching dealing with grey squirrels. We cannot wait another 40 years until we find a solution. This proposed new clause cleverly does not state what the solution should be, but that there has to be an animal damage protection standard. That is a clever way to tackle the problem and I commend it.

To conclude the anecdote of the never-ending Ministry of Agriculture rabbit research programme, I told that story in 1998 to the new Minister, who is now the noble Lord, Lord Rooker, who chuckled and said, “Don’t worry, David, we’re not so daft as to do that.” Two weeks later, he came steaming up to me and said, “You’ll not believe this, we’re still spending £700,000 on rabbit research”. Policies and Ministers change, but academic research goes on for ever. I am told that there has been an amazing scientific breakthrough in dealing with squirrels. The current research shows that contraceptive pills for grey squirrels, I can tell the noble Earl, Lord Kinnoull, are apparently 100% effective—but they still cannot get the squirrels to eat them. It will take 10 more years of research, the experts will no doubt advise the Minister to pay for. Omnia mutantur nihil interit: Everything changes but nothing is lost.
