Tree Health in England

Baroness Fookes Excerpts

Thursday 9th June 2022 Grand Committee

[Baroness Fookes (Con)]

My Lords, I must first declare my interest as co-chairman of the All-Party Parliamentary Gardening and Horticulture Group—and what a mouthful that is to say. I would like to make a general point first about the three types of trees: there are those that are involved with forestry; those involved with woodland management; and those involved with arboriculture—the amenity parts of trees. I have a suspicion that the Government take the arboricultural side of things less seriously, and I hope I can be told I am wrong by the Minister when he comes to sum up. But they are an extremely important aspect when dealing with the health of trees.

I will not dwell on the issue of ash dieback, as it has been so comprehensively dealt with by the noble and right reverend Lord, Lord Harries, and others before me. I want to concentrate now on threats to come. I have been told that there are at least 47 pests and diseases beyond our shores, at present, but which may reach our shores in the next decade. Therefore, it is extremely important that every measure possible is taken to deal with that issue.

I spoke a year or two back to the director of horticulture at Kew’s Royal Botanic Gardens and I thought that their policy on new trees was a lesson for us all. First, they seek to buy from British sources only—British nurseries. If that is impossible, they will buy imported trees but those are then, rather like dogs of old, quarantined for six months in a special area before they are allowed out into the wider community.

That may be a counsel of perfection not possible for all, but it chimes with the point made by the noble Baroness, Lady Young, that we need to increase production in tree nurseries by helping and supporting them. I guess there is a limit to the number of sites on which they can produce, but it is important that they have some knowledge of the future orders that might be placed by local authorities or the Government. They need good warning, because it takes up to five years to produce the sorts of trees required for such schemes.

Next, it is important that the public are warned loudly, clearly and frequently about the dangers of bringing in a few little plants that they saw abroad and think would be rather nice to have at home. That is one way in which pathogens, pests and diseases can come in.

Finally, there is the position of the Government in dealing with both research and, more importantly, biosecurity measures for imports. I hope there will be both thoroughness and speed because, if things take too long and are too bureaucratic, living creatures may die on the way to their destination. That must be avoided. It would help if the Government had a list of the most dangerous pests and diseases and concentrated their controls on those they regard as the most difficult to deal with. That would help the nursery trade and others to deal with a very serious situation.

Among the 47 is the emerald ash borer. On this pessimistic note, because it might nibble horribly at trees that we hope are resistant so must not get in at any cost, I rest my case.
