It has been called the "Domesday book of British wildlife" - a new publication, compiled by 40 of Britain's leading scientists, provides a complete picture of the state of the country's wild animals and plants.

The book, called Silent Summer, makes for some grim reading. Farmland birds, brown hares, water voles and many butterflies and other insects are in decline because of changing farming practices and loss of habitat, it says.
There are, however, some success stories. The otter, which between 1957 and the Seventies disappeared from 94 per cent of its habitats, is now back at more than a third of those sites, thanks to a special conservation programme.
And, controversially, the book credits field sports with helping to conserve several species, saying activities like hunting and shooting are "almost universally good" for the hunted species and many other species living in the same habitats.
The 600-page book was written by a team of experts and edited by Professor Emeritus Norman Maclean, of Southampton University's School of Biological Sciences, and a leading UK authority on fish genetics and genomics.
The book records how some farmland birds, including the skylark, have seen their population fall by more than half in recent decades. Farmland birds are a key government barometer for measuring the countryside's health.
Other species, including the yellow hammer, turtle dove, grey partridge, willow tit, spotted flycatcher, wood warbler and pied flycatcher are also in serious decline.
Robert Robinson of the British Trust for Ornithology says in the book that half the 220 bird species in Britain and Ireland " are of conservation concern". Climate change is a threat but deterioration and loss of habitat is a bigger problem, he says.
The dramatic fall in insect populations in the past 20 years has had a knock-on effects for other animals, especially birds and mammals. British butterflies in trouble include the Large Heath, Duke of Burgundy and Lulworth Skipper.
The brown hare, which has been in decline in the UK since the 1960s, has suffered from an increase in the number of predators – mainly foxes – and loss of cover, according to the book. There are an estimated 800,000 hares in the UK and although not rare or endangered, the mammal is one of the Government's priority species for conservation.
In addition to the otter, other species that have benefited from targeted measures include the buzzard – up by over 50 per cent – and the red kite, which was on the brink of extinction and now boasts a population of 1,000 breeding pairs in the UK. Sea birds are flourishing and badgers, helped by strict legal protection, have seen their numbers rise to more than 300,000.
Prof Maclean told The Sunday Telegraph: "The book is like a Domesday Book of British wildlife. There are serious concerns about many species of birds and insects. The problem is chiefly man-made and the solutions can be man-made too.
"But the picture is mixed. The evidence suggests that targeted conservation campaigns work. We have to protect the species in danger because so many other species depend on them for survival.
"And we should also protect them because wildlife is important to our quality of life."
Sir David Attenborough says in the book's foreword: "This book... gives us a benchmark. It is invaluable now and in the future it will be irreplaceable."
The book highlights the importance of field sports to the wellbeing of wildlife. Robin Sharp, Chair Emeritus of the International Union for Conservation of Nature, says that "field sports ... have been almost universally good for the hunted species and the non-hunted, non-predators that thrive in the same habitat".
Prof Sharp praises foxhunting and reveals that 86 per cent of woodland managed for hunting had vegetation cover – important for other species – compared with just 64 per cent in unmanaged woodland.
Managed areas also had an average of four more plant species, greater plant diversity and more butterfly species than unmanaged areas.
Prof Sharp also reports on a study of three areas in central England which found that all owners of land used for hunting and shooting had planted new woodland, compared with only 30 per cent of landowners who did not host hunts or shoots.
"This suggests that those who hunt and / or shoot provide significant conservation benefits," he said.
Prof Sharp calls on hunters and shooters to make more effort to explain the benefits of their activities to conservationists, policy-makers and the public.
"Overwhelmingly the target species for field sports have fared well over the last century ... More game-keeping, game crops and habitat management would undoubtedly achieve even more."
