My Lords, my noble friend is right to highlight the biodiversity costs of losing ash trees. It is why, with research, we have found the most tolerant strains. We will be planting a large plantation of the most tolerant strains next year so that we can ensure that ash retains its important part in our ecosystems. We have also produced a toolkit and we are working with local authorities as, clearly, not only is health and safety involved but we want to ensure that the most tolerant trees are conserved. A lot of work is being done on that. For instance, I commend Devon County Council for its policy that, for every tree that is felled, three are being planted. That is a message for everyone.
