My Lords, I agree with the earlier speakers that this part of the Bill needs to be strengthened. I should say to my noble friend Lord Goldsmith with regard to the amendment of the noble Lord, Lord Chidgey, why just chalk streams? I know how vital they are but any river will tell you about the environment of that area and its quality within the river.
I have a little bit of good news for my noble friend on the Front Bench. I recently spent three days in Dorset and, driving back, I had to wash the windscreen of my car to get rid of the bugs. It is the first time in many years when I have had to do that. If bugs are getting on to windscreens, it means that something is turning around slowly in nature. It is a good start and I hope that we will all be doing what I had to do on a much more regular basis. I agree that it is desperately boring to do, but it is far better to be bored doing it than not to have nature.
Virtually all land in the UK is managed. There is very little, if any, truly wild land left. When we are considering biodiversity, we must not forget that the land also has to produce food for the population. I again ask my noble friend on the Front Bench the question I asked at Second Reading, or possibly on the first day of Committee—I cannot remember. Does he agree with the figure that 21% of our agricultural land has to be taken out of agriculture and put into bioenergy fuels and trees? If that is the case, it means a 10% increase in the productivity of all the other agricultural land. That will mean a lot of intensification but it can be done if we do that cleverly with supporting biodiversity.
Here I want to talk about something that has almost become a dirty word: management—land management and biodiversity management. We could improve the biodiversity in this country very quickly if we followed the simple rules of getting the right habitat, the right species protection, proper winter feeding and control of predators. That is the four-legged chair on which biodiversity depends. I know that the Agriculture Act will address some of that but it will not necessarily address winter feed and certainly not predator control. The winter feed situation has been hugely compromised by the increasingly efficient agricultural machinery that farmers use and the height at which crops can be cut, leaving little for wildlife.
I mentioned foxes and badgers earlier. It was in that context that I felt that my noble friend the Minister had not answered my questions. What will the Government
do to ensure that there is proper predator control carried out in a humane way? I am not talking about the extinction of species but getting a balance. If we are going to get back lapwing, curlew and waders, predators will have to be controlled. It is not just a question of foxes and badgers but deer. They have ruined hedgerows for ground-nesting birds and nightjars, and decimated some trees. In an increasingly urban southern half of England, deer control is becoming a major problem to undertake but if we do not do so we will affect wildlife in a hugely different way. It is not just a matter of our actions as human beings but of nature working within nature.
I know there are certain things over which we have no control, such as climate change. It is bound to affect our biodiversity in ways we do not know. As the noble Lord, Lord Chidgey, will know, warmer winters and cooler summers are affecting salmon migration and its appearance in rivers. It is to be hoped that we will do something about that in long term, but it is not a short-term problem that we can solve. Nor can we solve the problem the north winds this spring have caused the bat population—that is not strictly within our hands. My friend, the noble Lord, Lord Krebs, talked about the blue butterfly, which is weather-dependent. We have seen a huge increase in the red admiral thanks to a slightly warmer climate, but the other side of that equation is that we have lost a whole lot of butterflies because of the change in the climate. I wonder whether the blue butterfly that the noble Lord mentioned will suffer in the future.
In this debate, on getting an abundance target and improving biodiversity, I hope my noble friend will tell us about the practical problems that organisations are trying to solve. These organisations, such as the Game & Wildlife Conservation Trust and the Nature Friendly Farming Network, are doing huge amounts. They will need some more help and some more drive from the Government as well. Rather than just setting targets, it is the practicalities on the ground that matter.
