Natural Environment — House of Lords, 2015-01-15
Topic: Environment
Michael Nicholson Lord (Conservative, Centre-right): My Lords, I add my congratulations to the noble Lord, Lord Callanan, on his excellent maiden speech and I am sure we look forward to further contributions from him I am extremely grateful to the noble Baroness, Lady Bakewell, for obtaining this debate today which allows me to talk about one of my favourite topics: trees, particularly ones in urban areas in what are currently called hard landscapes. Trees are like the humble bee. They do a massive job in the environment and are taken for granted by most people, yet without them our very survival would be threatened. I remind you what an incredible job trees do. They look attractive. They take in our waste carbon dioxide and give us in return precious oxygen. They provide shelter and are barriers to both pollution and noise. They help to cool the urban environment and manage storm-water run-off. They have been shown to have a positive effect on the nation’s health. In short, they are quite simply indispensible Yet the question that I want to pose is: are we making the most of this incredible asset? We use trees to adorn and enhance our finest buildings and to hide and camouflage our ugliest. When applying for planning permission, architects embellish their drawings with pictures of mature trees, yet so often, when the development takes place, for reasons of finance or inadequate aftercare the trees as envisaged never appear It must be obvious from what I have said already that what is needed is a nationally co-ordinated approach to the design and management of hard landscapes. This would ensure the maximum and most imaginative use of trees and guarantee both their planting and their aftercare—to decide not just what type of tree to plant but to take into consideration its ultimate size, crown spread, root spread, disease resistance, the soil type in which it will flourish and its proximity to underground utilities, as well as things such as its leaf drop, fruit production and aftercare needs, and 1,001 other issues Clearly the Government have a role to play in this, although I am not quite sure which department it currently comes under. However, help is also at hand in the form of an organisation called TDAG, the Trees and Design Action Group. This organisation, now a charity, was formed in 2007 with the ambition to create a very broad network of expertise across the built and natural environment, sharing a common understanding that trees have a major role to play in the health of our cities Perhaps I should declare an interest—one that is not in any way financial. Many years ago, I was for some time the president of the Arboricultural Association, which is a member of TDAG. The group contains the widest possible spectrum of organisations concerned with these issues, from local authorities to landscape architects, from civil engineers to nurserymen, and from banks to the Forestry Commission—too many to mention but all with the same aim: to get more healthy trees in our cities and thus improve the health of those who live there TDAG has produced two excellent publications: Trees in the Townscape and, last October, Trees in Hard Landscapes: A Guide for Delivery, which I am sure the Minister will be aware of, since his colleague, the noble Baroness, Lady Kramer, wrote the foreword for it. I urge him, if he is not already doing so, to lend his weight to the distribution of these guides, or more particularly their contents, so as to co-ordinate and encourage the most enlightened and best practice everywhere We must use all the experience available to us, together with our imaginations, to break new ground and to break out of our sometimes routine thought processes. Many years ago on a lecture tour in the United States, I found myself in Philadelphia. In those days, Ginkgo biloba, the maidenhair tree, was relatively rare in the United Kingdom. To my astonishment, in Philadelphia it was used as a street tree. It was everywhere. If it was an ideal street tree there, why not here? That is a lesson I have never forgotten. I believe it is now called "thinking outside the box" It is not just housing, office or town-centre develop- ments that present challenges and opportunities. What about business parks, industrial sites, motorway and railway embankments, and roundabouts? Opportunities abound not always with big trees but sometimes with small trees, shrubs and low-maintenance ground cover, but always with a mixture of experience and imagination to produce the best possible use of the ground available for the maximum effect I should like to deal briefly with two other important topics: tree importation and woodland protection. Following the importation of ash dieback from Europe, there was a call, including one from me, for a reduction in the number of imported trees and for much more reliance on home-grown stock to reduce the ever present and very real danger to our tree population. Sadly, figures that I obtained through a Written Question show that in the last planting season we imported more trees than ever. I acknowledge that this is not a simple matter. It involves long-term planning, with appropriate commitments and contracts. But trees are a long-term business, and getting it wrong again would be disastrous Perhaps a quarantine system is the answer, at least in the short term. A company called Barcham Trees, based in East Anglia, has introduced its own quarantine system. It says that it will not import trees and sell to customers for immediate planting, and that, "All imported trees will be held on the nursery for one full growing season during which time they will be subjected to rigorous inspection for pest and disease. This includes systematic and regular DEFRA visits" I do not know whether other companies are doing this, but if it is not already happening, perhaps the Minister could look into the merits of that system. Audit trails for trees are also important, so that trees sold by any particular nursery can be easily traced. Caring for existing trees is vital, not just in urban areas but in woodlands too, particularly ancient woodlands. Houses can be demolished and rebuilt in a matter of months, but an invaluable ancient woodland, if lost, is lost for ever. The Woodland Trust tells me that it is currently fighting 400 cases where woodlands are under threat. I know the Minister has a great interest in woodland, and I urge him to do all he can to preserve it wherever possible We must care for all our trees, old and new. I would say to the Minister, who I am sure loves his trees, "Don’t listen to those who say you never see the results of tree planting in your lifetime". Trees make their presence felt in a few short years, and what better legacy could a Minister leave than to have significantly increased the nation’s tree cover, particularly in our towns and cities?
