My Lords, I am delighted to follow my noble friend the Duke of Montrose, who speaks with great authority and knowledge on these issues. I thank the noble Lord, Lord Greaves, for introducing this little group of amendments and for the opportunity to discuss native—and, perhaps I might say, non-native—species. I will limit my remarks to Amendment 19. The biggest threats to native species, as I see it, are the uninvited, unwelcome guests of non-native species. For example, I have seen first-hand the damage that Himalayan balsam can cause, particularly along the length of a stream; how difficult it is to eradicate; and the time and expense taken up by land managers in this regard.
When I was on the Select Committee on Environment, Food and Rural Affairs in the other place, we looked at this in a report on Chalara, which causes the ash tree dieback. I hope that when my noble friend the Minister sums up she will confirm that the practice by which, for some bizarre reason, seeds used to be exported from this country to others such as Denmark, Poland and others where the disease existed, and then
we reimported those trees as saplings from those countries, has been stamped out and will not be repeated. It brought a high level of infection to this country. We now have a number of endemic diseases in the horse chestnut, which I fear may go the same way as elms did. We heard only this week in the Lords of a new threat, particularly to lavender and other plants, from Xylella fastidiosa.
I again commend the work of Fera—I know that it has changed its name, forgive me—which does great work in this regard, as well as on ash tree dieback. If the Government were to look favourably on this little group of amendments, I invite my noble friend to consider whether farmers and land managers could be reimbursed for the work that they do in trying to protect our native species from these unwelcome and uninvited non-native species.
