The Earl of Caithness (Con)
My Lords, for biodiversity to be diverse and flourish in the UK, it needs habitat, species protection where appropriate, the provision of winter food for birds and animals and sensible predator control. Given all the protection and proscription that we have enacted over many years for habitats and species, one must ask why biodiversity is still in decline. Clearly our policy has failed. We are not good at providing winter food due to farming methods and efficient modern farm machinery. Hopefully ELMS will help with that. More importantly, we are increasingly bad at management, including sensible and humane predator control.
Mankind has changed the environment in which all species live. There has been the removal of apex predators, the introduction of alien species, the loss, degradation and fragmentation of habitats and pollution. Nature will always find a balance but, often, it is not the balance that we want and leads to a reduction in biodiversity, as the noble Lord, Lord Teverson, and the noble Baroness, Lady Young, said.
Take, for example, Auchnerran farm in Aberdeenshire, owned by the Game & Wildlife Conservation Trust and managed for biodiversity. This year alone, two-thirds of the lapwing nests have already been destroyed by badgers. This is a property that is farmed for biodiversity. Similarly, at the trust’s property in Allerton, Leicestershire, there have been no hedgehogs for seven years and no waders for 10 years because of predators.
The noble Baroness, Lady Young, mentioned trees. Of course, trees are suffering hugely from a deer problem. Deer are notorious browsers and are bad for coppicing. They reduce the understory, which is bad for nightingales, primroses, primulas, nesting birds, butterflies and other species. Of course, it suffers from grey squirrels too.
We have a severe problem, not an emergency, but we can solve that problem if we and the Government get our policies right.
