Environment Bill

Earl of Kinnoull Excerpts

Committee stage
Monday 12th July 2021 Lords Chamber

[The Earl of Kinnoull (CB) [V]]

My Lords, it is a great pleasure to follow the noble Baroness, Lady Young of Old Scone, who spoke with her typical authority and strong logic. I declare my interests as set out in the register, particularly those in respect of agriculture and as chair of UK Squirrel Accord, of which more later.

I shall speak to Amendment 260A, which stands in my name, and Amendment 259 in the name of the noble Baroness, Lady Young of Old Scone. One plank of this Bill is afforestation. We have heard much throughout the many days of debate on the Bill about the benefits of carbon capture and the biodiversity dividend of afforestation. It is worth recalling that the level of afforestation in the United Kingdom in 1919, just after the First World War, was just 5%. Today, it is 13%, but the 2021 EU factsheet on afforestation for the EU shows that it is 37% afforested. In his very good speech at Second Reading, my noble friend Lord Cameron of Dillington pointed out that it is important to balance food production with forestry on our limited land area, but I still feel that 13% is the wrong number and needs to go up significantly. I agree with many others who have said that over the course of our many days.

The problem is that simply planting trees is not enough. Amendment 260A is about the management of the main animal damage threats, while Amendment 259 is its biosecurity analogue. The squirrel problem is very simple in that grey squirrels ring-bark trees between the ages of about 10 and 40 and suck out the sap. This damages the trees and kills many of them. UK Squirrel Accord was formed five or six years ago to try to combat this at a UK level. It comprises the four Governments, their nature agencies, the main voluntary bodies and the main commercial sector bodies. There are 40 signatories overall. It seeks to co-ordinate not only communication among those bodies so that everybody knows what is going on but the use of science in controlling squirrels, and that science will of course be able to be used for the control of deer.

The key thing at the moment is the fertility control project, which is getting to the end of its third year at the Animal and Plant Health Agency’s main laboratories just outside York. The project will do exactly what it says on the tin, which is to control the fertility of grey squirrels and therefore shrink their numbers dramatically.

This year saw a very interesting piece of academic research by the Royal Forestry Society on the level of the problem that the grey squirrel poses to afforestation. It is called An Analysis of the Cost of Grey Squirrel Damage to Woodland. It is quite a lengthy report, and I shall not give your Lordships all the details, but 777 land managers were surveyed. They said clearly that the greatest threat to them in trying to grow woodland was the grey squirrel, and 56% of them said that they were experiencing damage quotients of between 35% and 100%, with only 14% feeling that the damage quotient was less than 5%. I should say in addition that the oak tree, which is one of the most iconic species for our country, is the greatest supporter of biodiversity, with some 2,000 species supported by oak trees.

The UK Squirrel Accord and its associated voluntary bodies are extremely worried about there being safe zones for squirrels because some people do nothing. The biggest problems we see in those safe zones are patrolled by Amendment 260A. First, if you have been in receipt of a grant or if you are a public body—this is a very big problem—you must comply with the animal damage protection standard. If you are somebody else, you will be encouraged to comply with it. Given those who are interested enough to participate in the UK Squirrel Accord, I think people will obey that, but I feel that some motorway and railway agencies in particular are doing nothing at the moment and therefore have a lot of safe harbours for the squirrel.

I will say a brief word on the cost of compliance. I congratulate the National Forest Company, which has employed volunteers to help with some of its control issues, greatly reducing any costs that may be involved. I believe there is a significant number of volunteers—the UK Squirrel Accord is very much in touch with them—who would assist with that and therefore help with the cost element.

I turn briefly to Amendment 259. I feel that the science will get there for Amendment 260A in the end, and we will have sufficient scientific weapons to be able to reduce the level of grey squirrels in the country so that it will be commercially possible to plant broadleaf trees in the south of England again. We will hear about that from later speakers. The difficulty is that the disease problems associated with importing trees, particularly pest problems such as the oak processionary moth, fill me with an appalling dread. Here I very much agree with what the noble Baroness, Lady Young, said just a moment ago. It is important to be a bit like a Chinese doctor and act before some of these problems arise, and act very strongly indeed. Both these amendments are enabling provisions for afforestation. We will not get there without them.

[Lord Lucas (Con) [V]]

My Lords, I am very pleased to be able to follow the noble Earl. I declare an interest as an owner of a plantation on an ancient woodland site, mostly replanted in 1986. I reckon that my cumulative loss to squirrels is about 60%. There are areas of the wood where nothing has survived except the coppice regrowth, and a lot of that is damaged. I have been trying to control squirrels throughout that time. This is a really serious problem if we want to take trees seriously, particularly if we want them to be commercial. I therefore very much support Amendment 260A. It would be a really useful way to go, getting us all working together in the same direction.

Deer are important too. Those who know the border between Wiltshire and Dorset will know the troubles the RSPB has had in Garston Wood with the herd of fallow deer it had there. It got zero regeneration at the end of the day because there were just too many deer. It has now excluded them, which is not fun for the local farmers, but at least it solves the RSPB’s problem. However, generally we have to recognise our position in this ecosystem. We are very important as the top predators—the controller of what happens with herbivorous activity—and if we want particular species and kinds of things to grow, we must act on that responsibility.

We need to start to understand how regeneration is working around us. Oak regeneration does not seem to be happening at all, something that is echoed by other people in the south of England. I do not know what circumstances need to change to make the ecology right for that. These are things that, with a big ambition for forestry, we need to understand. We do not want to have to be for ever planting trees; we ought to be able to rely on a pattern of regeneration.

I am very much in favour of the direction of Amendment 259. We need to be quite strict about the diseases that we let into this country. We have a very limited degree of biodiversity when it comes to trees and shrubs; we have about 30 different ones, around one-tenth of what an ideal temperate woodland would have by way of variety—courtesy of the Ice Ages, mostly, and the opening of the Channel but also, subsequent to that, the effect that man has on restricting the natural movement of plant species. We need, as the Forestry Commission is setting out to do, to improve our genomic diversity within species as well as the number of species that we have.

While I do not at all resent the activities of the Romans and others in bringing across chestnuts, for instance, or the buddleia in my garden—a cousin to many that are spread over the south downs—I do not think additional biodiversity hurts us. We are a very impoverished ecosystem and should be able to stand some introductions—but not, please, diseases. We have seen the devastation caused by ash dieback around here in Eastbourne. With a limited ecosystem, each disease is a big hit, and we do not want to risk more of that because it will take a very long time before we have a more diverse forest population.

However, I am not convinced by Amendment 258. As I said, I own a plantation on an ancient woodland site, and an SSSI designation would be a disaster. There is so much needed to do to make it better. The point of an SSSI is that you pick on a bit of landscape that is as you wish it to be, and the focus is then on keeping it as it is and making it difficult for people to change it. A plantation on an ancient woodland site means a lot of restoration to do, and you do not need the level of bureaucracy that goes with being an SSSI. I would be happy to have something to give it greater protection against invasion by planners but not something that stops the woodland owner from making it a better wood.

--- Later in debate ---

[Lord Goldsmith of Richmond Park (Con)]

My Lords, I have had commitments from the MHCLG that our protections for trees will be improved and enhanced, and will not move backwards, but I will continue to press home that case. I am seeing the Secretary of State in a matter of days to talk about this and a number of other issues, and I will raise the points that the noble Baroness raised in her speech today.

[The Earl of Kinnoull (CB) [V]]

I am also sorry to delay matters. I thank the Minister for his response, but I am afraid he did not address my point about refuges and safe areas caused by governmental bodies not controlling the problems of squirrels and deer. They were listed in subsection (3) of my proposed new clause. To save time, I wonder whether he might add to his lengthy list of things a meeting to discuss that, because it is a very serious area. If we do not address that problem successfully, as I and many others pointed out, we will not be allowed to do the forestation we need.

[Lord Goldsmith of Richmond Park (Con)]

I am very happy to meet and will be in touch.
