I have also got rid of Japanese knotweed—I have not had much success with Himalayan balsam, though.

I thank the noble Lord, Lord Roborough, for Amendments 253, 296 and 297, and the noble Lord, Lord Cromwell, for Amendment 253B. I will consider these together because they all relate to invasive non-native species and the nature restoration fund. The Government recognise the impacts of invasive non-native species on our native species and ecosystems. As the Minister for invasive non-native species, I appreciate the noble Lords’ intentions in tabling these amendments, but they do not align with the targeted nature of the nature restoration fund.

However, I reassure noble Lords that I have a particular bee in my bonnet about how we best tackle invasive non-native species, because they can have a devastating impact on our native biodiversity. Himalayan balsam means that nothing grows at all, and it wrecks riverbanks. However, it is about not only what is here at the moment and how we manage it but how we stop more invasive species coming in. That is a huge challenge. While I am on that subject, the noble Lord, Lord Lucas, asked about the list—it is retained EU law, but we have been reviewing and amending it in order to tailor it to UK circumstances.

Amendment 253 would require Natural England to take action to eradicate the invasive non-native species that could negatively impact an EDP’s environmental features. The legislation already allows invasive non-native species control to act as a conservation measure, where this would support the action of Natural England to materially outweigh the impact of development on the relevant environmental feature. However, we should recognise that it might not always be the best option in terms of environmental impact, value for money and delivery considerations, such as the need to secure the overall improvement by the EDP end date.

Requiring action to eradicate invasive non-native species, regardless of these considerations, could delay EDPs, increase costs, and limit the ability to secure positive environmental outcomes. With these amendments, the Secretary of State would be required to revoke an EDP—even one delivering effectively for nature—because of the presence of a single grey squirrel, which does not make sense in the bigger picture. Making EDPs contingent on mandatory eradication in this way could also make them unviable. On the grey squirrel question, the noble Lord asked about the sterilisation programme. To confirm, the programme is ongoing, and is being supported by Defra.

Amendment 253B, tabled by the noble Lord, Lord Cromwell, seeks to require bodies exercising powers relating to an EDP to ensure that legal obligations under the Weeds Act 1959 are “publicised, observed and enforced”. The Weeds Act grants powers for the Defra Secretary of State to serve landowners with a requirement to remove the weeds specified within the Act, and ensures that landowners retain responsibility for their own land, instead of public bodies needing to act.

EDPs are a targeted tool to address the impact of development on specific environmental features. Introducing a broad obligation for Natural England, and others exercising responsibilities relating to EDPs, would expand the scope of EDPs, and risk diverting focus from their core purpose. The noble Lord, Lord Cromwell, and others discussed ragwort. I assure the noble Lord that there is nothing in this legislation that would preclude Natural England or others from taking action in line with the Weeds Act, such as reporting the presence of ragwort where this is encountered, or from appropriately removing such weeds where Natural England, or delivery partners, are delivering conservation measures on the ground. With these explanations, I hope that the noble Lord, Lord Roborough, will withdraw his amendment.
