My Lords, in moving my Amendment 253, I will also speak to my other amendments in this group. It is an embarrassment that in our small, wealthy island nation, there are, according to APHA, over 2,000 non-native species, of which 10% to 15% become invasive and pose a serious threat to our biodiversity and environment. We must make intensive efforts to control and eliminate those species to protect our own besieged biodiversity.

The grey squirrel has pushed the red squirrel out of much of our woodlands and now destroys countless young trees every year, making it almost futile to plant native broadleaves in my home county of Devon and many other parts of the UK. What progress is being made with the research into the sterilisation of grey squirrels, and when will that treatment be expected to be made generally available?

Himalayan balsam and Japanese knotweed have invaded our river systems, displacing our native flora and upsetting the ecology for animals and fish living in those waterways. I commend the Tamar invasives group for the work it has done in controlling these invasive plants under the auspices of the Tamar Valley National Landscape in that area. What similar work is being done elsewhere in the country to eradicate these species?

Signal crayfish are present in many waterways and reservoirs, spreading disease that kills our native crayfish and predating on our migratory and freshwater fish species. Muntjac deer are spreading rapidly across our country, feeding on our crops, damaging fences and stripping the bark off young trees. Numbers are out of control.

The purpose of these amendments is twofold. The first is to raise awareness of the damage that these and other species are doing to our environment. The Government need to change attitudes to these animals, birds and plants so that everyone in this country takes steps to eliminate them from their gardens, farms and land.

The second purpose is equally serious. I cannot see how any environmental delivery project funded by this new nature restoration fund can be judged to be successful if non-native invasive species are still present on the land within the project after five years. It simply does not make sense that the EDP can have done an acceptable job on the site if those species remain in place, attacking our much-loved trees, brown squirrels and aquatic species.

Should the Committee support this amendment, I fear there is a risk that Natural England could then choose sites that are not infected with those species. Can the Minister assure the Committee that would not be the case? I think that all who know and love our beautiful countryside appreciate how difficult a task it would be to achieve this even in these limited areas, but it is not impossible, and it is crucial. I look forward to the noble Lord, Lord Cromwell, introducing his own amendments. I beg to move.
