My Lords, I echo the words of the noble Lord, Lord Lucas. First, I would like to address the reintroduction of native species. Down in Devon, we have seen the relatively successful and very interesting reintroduction of beavers—ironically, in the River Otter. That has had some success but also some major challenges, not least for landowners, whose land gets flooded unexpectedly, requiring the proactive management of those beavers and moving them on.
Discussion is increasing around the reintroduction of pine martens as a means of controlling the grey squirrel population, although it is pointed out that grey squirrels live in urban centres where pine martens do not, so it would be very difficult to control grey squirrels that way. In the wilds of Scotland—the Glenfeshie Estate—the reintroduction of large herbivores is being considered. I was at a talk given recently by the brother of the noble Lord, Lord Goldsmith, the Minister, who made reference to the reintroduction of wildcats to Dartmoor. I have resisted the urge to stray into the Dartmoor Hill ponies area, since they are so ably represented by a number of noble Lords. However, I would resist the reintroduction of wildcats to Dartmoor, if only for the dear Dartmoor pony’s sake.
Rewilding is a very complicated issue. I congratulate the Knepp Estate on its huge enthusiasm and the interesting research it is doing, but nature does not
take care of itself in this landscape. We have created this landscape, we are responsible for it and we cannot divorce ourselves from that responsibility.
Rewilding is not a new concept. Three hundred years ago, the landscape around me was heavily farmed and ornately gardened. About 270 years ago, it was rewilded with the creation of a deer park, which exists to this day. That is a form of rewilding, creating a primordial, idyllic landscape with deer grazing under trees and eating conkers and acorns. It is, I agree, a fantastic landscape with remarkable biodiversity and it provides a healthy harvest of venison, but it is not profitable. It is heavily subsidised by HLS and ELS, and even then, it is not profitable. The only way we make it break even is with a series of concerts, which were so ably promoted on Tuesday by the noble Lord, Lord Mann.
Rewilding does not necessarily create a profitable and vibrant landscape, and we need to be very cautious in imagining it does. However, there are areas of the country that may benefit from it—I am thinking of marginal areas that are not profitable farmland but that should not be allowed to go completely to wilderness. They could be rewilded, but only if it can be done on a landscape scale, creating landscape-scale environmental corridors and providing remarkable benefits for all in joining up environmental and species habitats.
