My Lords, I declare my interests as stated in the register—in particular in forestry. We have to learn from past sad experience—for example, over Dutch elm disease, which has wiped out the great majority of all the elms of southern England. At this very moment, we are grappling with ash bud disease, which can make the timber of ash completely useless, except as firewood. Other, lesser infections and importations have affected chestnut trees, oak and larch, and one hopes that they are not spreading or getting more serious. Invasive weeds have been mentioned, notably by the Minister, and on quite a few occasions your Lordships have discussed Japanese knotweed, but I will say no more about that.
I notice that of course the regulations are unamendable —incidentally, I apologise for not having been present when they were discussed earlier—but I trust that the Government have devised the very best possible protection. As an island, we are better placed than those with land frontiers to protect our stock of plants and trees, but we should try to benefit from our natural advantages and devise the very best possible protection.
