Tree Health in England

Baroness Bennett of Manor Castle Excerpts

Thursday 9th June 2022 Grand Committee

[Baroness Bennett of Manor Castle (GP)]

My Lords, I thank the noble and right reverend Lord, Lord Harries of Pentregarth, for securing this really important and interesting debate. Like the noble Baroness, Lady Fookes, I am going to concentrate on what she labelled as amenity trees—what I might call street trees or urban trees in general. That is because I want to put some positive spin in here. We need to think about some positive news; we have heard lots of negative news and there is certainly a lot of that around on tree health.

I can attribute campaigners in Sheffield as playing a really important role in raising understanding of the importance of street trees, in particular to public health and well-being, as well as to biodiversity and in cooling our climate emergency-heated cities as well. I note that 19 cities in the UK have now taken the Tree Cities of the World award. A number of these were awarded last month. Sheffield was among them and it is notable that Leeds, Hull and Bradford were too, perhaps influenced by all the public interest in the news that came out of Sheffield, so we are really seeing the valuing of street trees.

But just as we need trees for healthy cities, trees need a healthy environment to flourish in cities. I pick up the point of the noble Earl, Lord Caithness, who talked of the need to a healthy phytobiome of a diversity of trees. Of course, what we also need is clean air; it is good for us and for the trees. I have to point here to my noble friend Lady Jones of Moulsecoomb’s Ella’s law clean air Bill, which is now in your Lordships’ House.

Hard surfaces make trees chronically stressed if they are not given sufficient space, so we desperately need to think about the planning and design of our cities for people and trees. Taking note of the point the noble Earl, Lord Caithness, made, I am not going to say “the right tree in the right place”, but I am going to say that we need the right tree in the nursery. Lots of people have been saying how much we need to grow so many more of our own trees, but we need to think about what kind of trees we are propagating in our nurseries to be street trees. What kind of signals are we giving to the industry? At the moment lots of the street tree plantings are very small rowans and birches, but we want to see the addition of some of those magnificent trees the Victorians planted—the big specimens that truly shade and enrich our cities in ways that little saplings meant to be lollipop trees are never going to.

We have to think about how we make sure we plant trees in cities so that they survive. In Britain, the current figures suggest that around 13% of street trees die in their first couple of years. In a study in Canada, 50% were dead within one year, so we really need to look after our trees.

Finally, I want to focus on a question for the Minister. There is a desperate shortage of trained arborists. The Institute of Chartered Foresters estimates that we need 70% more trained people to meet the Government’s tree-planting goals. Thinking about the pressures on the health of our trees, we desperately need the people who can look after them. I would be interested to hear from the Minister what the Government plan to do to tackle that issue.
