My Lords, I start by confirming my support for all three of the amendments in the name of the noble Lord, Amendments 253, 296 and 297. However, I caution the use of “non-native”; it is the invasive aspect that is the problem. What could be more English than a rose? What could be a more typical English fruit than an apple? Both of them originate from central Asia—they are not natives. However, I entirely take the point about invasive species.

Amendment 60, already debated, referred to guidance on planting along highways. There was much discussion about trees and wildflowers. I enjoyed reading what type of tree the noble Lord, Lord Moylan, might represent, which might repay people who want to look it up in Hansard. One plant that grows along our highways which was not mentioned in the earlier debate is ragwort, the bright yellow flowering plant seen everywhere alongside our highway network. Through lack of enforcement of existing legislation, this invasive plant has become a menace to the environment, animals and agriculture, and action to control it is long overdue. Once it has flowered, ragwort produces seeds that, like dandelions which people may be more familiar with, come with a downy parachute which means they float far and wide on the breeze across the countryside and into farmland, where they take root, produce more seed, and so on.

Ragwort is poisonous to livestock, and it is not advisable for people to touch it with their bare hands, although I spend many unhappy hours pulling it up myself with my own bare hands, as I am sure many other Members do. Grazing animals leave it alone while it is growing, but where a field is cut for hay or silage, as is the case on many grassland farms, it gets incorporated into the bales, animals cannot detect it, and they are poisoned by it. Finally, areas set aside for environmental benefits, such as margins for wildflowers, quickly become choked with ever-expanding stands of ragwort.

So much for the biology; what about the law? Ragwort is what is called a notifiable weed, and landowners and occupiers have a legal obligation to control and remove it, particularly if it is spreading, causing a nuisance, or posing a risk to livestock. The Weeds Act 1959 and the subsequent code of practice on how to prevent the spread of ragwort outline these responsibilities. Failure to comply can lead to legal action, and/or the relevant authorities can issue a clearance notice requiring action to be taken to remove it. Unfortunately, this has not been enforced for many years.

As part of my research in tabling this amendment, I asked a Written Question about notices or prosecutions in the last 12 months. I was informed:

“In the past 12 months, no notices in relation to ragwort control have been served to National Highways, and there have been no prosecutions under the Weeds Act 1959 or the Code of Practice”.

I would bet that we could go back a lot more years than the last 12 months and the result would be exactly the same.

That is not good enough. Defra and the Environment Agency need to enforce the existing law and regulations. The Bill will create new areas of land controlled by a quango. This amendment specifically identifies this problem plant and requires that at least in the development of new infrastructure, proper controls are carried out, and—my favourite theme—enforced where necessary. That would be a start.
