Environment Bill — House of Lords, 2021-07-12
Topic: Environment
Donald Curry (Crossbench, Unknown): 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.
