OUR NATURE IS IN TROUBLE – this is the conclusion of a groundbreaking report launched today by a coalition of leading conservation and research organisations. Scientists working side-by-side from wildlife organisations across the UK, including Devon Wildlife Trust, RSPB, Buglife and Butterfly Conservation, have compiled a stock-take of our native species – the first of its kind in the UK. The report reveals that 60% of the species studied have declined over recent decades. More than one in ten of all the species assessed are under threat of disappearing. Peter Burgess, Conservation Advocacy Manager for Devon Wildlife Trust said: "Once familiar species including hedgehogs, lapwings and cuckoos, are declining in extent and numbers. Our seas too are in a fragile state as the recent death of thousands of seabirds due to pollution has shown." The report concludes that woodland, Culm grassland, heathland, upland, fresh water and wetland, coastal and marine species are all under threat in Devon. The State of Nature report will be launched by Sir David Attenborough and UK conservation charities at the Natural History Museum in London this evening. This report serves as a reminder to us all that nature needs our help and we can all do our bit to save it. Its authors are calling on people to support conservation charities and take action for wildlife. Sir David Attenborough, who wrote the foreword to the publication, said: “This groundbreaking report is a stark warning – but it is also a sign of hope. For 60 years I have travelled the world exploring the wonders of nature and sharing that wonder with the public. But as a boy my first inspiration came from discovering the UK’s own wildlife. “Our islands have a rich diversity of habitats which support some truly amazing plants and animals. We should all be proud of the beauty we find on our own doorstep; from bluebells carpeting woodland floors and delicately patterned fritillary butterflies, to the graceful basking shark and the majestic golden eagle soaring over the Scottish mountains. “This report shows that our species are in trouble, with many declining at a worrying rate. However, we have in this country a network of passionate conservation groups supported by millions of people who love wildlife. The experts have come together to highlight the amazing nature we have around us and to ensure that it remains here for generations to come.” Dr Mark Eaton, a lead author on the report and a Senior Conservation Scientist for RSPB, said: “This report reveals that the UK’s nature is in trouble - overall we are losing wildlife at an alarming rate. “Reliable data on these species goes back just 50 years, at most, but we know that there has been a historical pattern of loss in the UK going back even further. Threats including sweeping habitat loss, changes to the way we manage our countryside, and the more recent impact of climate change, have had a major impact on our wildlife, and they are not going away." Devon Wildlife Trust’s Peter Burgess will be speaking at the event alongside Sir David Attenborough. Peter commented: “For the first time in the history of the conservation movement we have a clear picture of how Britain’s special wildlife is faring. Nowhere is this information more important than in Devon, a county that supports the country’s most biodiverse parish {Braunton] and which is home to two of the ten most-threatened species in Europe [the marsh fritillary butterfly and the freshwater pearl mussel]. It’s a great honour to be involved in launching this report by presenting alongside Sir David Attenborough – someone that has done more that anyone else in reconnecting people with the stunning wildlife that we have in this country.” Peter continued, “None of this work would have been possible without the army of volunteer wildlife enthusiasts who spend their spare time surveying species and recording their findings. Our knowledge of nature in the UK would be significantly poorer without these unsung heroes, and that knowledge is the most essential tool that conservationists have. "Peter concluded, “It is time for us to take action to save nature and we are calling on people to give their support. We can all do something for nature, whether it is volunteering on a nature reserve, surveying species, making wildlife-friendly gardens, supporting campaigns or by becoming a member of a conservation charity."

- The total number of larger moths had fallen by 28% since the late 1960s and two-thirds of the 337 species monitored had declined, and 37% by more than half.
- 72% of butterfly species had decreased over the previous 10 years, including common garden butterflies that had declined by 24%.
- The UK has lost 44 million breeding birds since the late 1960s.
- In 16 counties, one plant species went extinct every other year.
- Britain's mammals have seen losses and gains, with decline of hedgehogs, the ongoing loss of red squirrels, and the recovery of otters.
- In 2010, Norman Maclean's book Silent Summer summarised dramatic declines in the UK's insect populations, and concluded that 'our wildlife is clearly in for a bumpy ride'.
- 80% of England’s Culm grasslands can be found in Devon. A survey of Culm Grassland in the early 1990s indicated that between 1984 and 1991, some 65% of the Culm Grassland area present in 1984 and outside of protected areas was lost. 80% of this loss was due to agricultural improvement, the rest due to afforestation, neglect or development.
- 30% of the Pebblebed Heaths lowland heathland were lost in the twentieth century to plantation, arable, improved grassland and mineral development.
- Devon is thought to hold 20% of the UK’s species rich hedgerows. The implementation of the Hedgerow Regulations 1997, together with the positive influence of agri-environment schemes, is likely to have halted the net loss of species-rich hedges. However, it is also likely that the condition of a number of hedges is continuing to decline due to a lack of suitable management.
- Between 1987 and 1991, it is thought that 24% of unimproved grassland sites within Devon had deteriorated due to inappropriate management, 24% of sites had deteriorated due to neglect, 4% of sites had been partly destroyed and 2% wholly destroyed.
- In 2007, Devon was estimated as holding 4,063 hectares of parkland and wood pasture. However, it is likely that well over 50% of working wood pasture and parkland has been lost to either scrub woodland and/or to arable/improved grassland over the last 50 years.
- Devon has the first Marine Conservation Zone around Lundy. Devon Wildlife Trust has been working for over 15 years to protect the Lyme Bay Reefs resulting in the development of Britain’s largest inshore marine protected area.
- The cuckoo has declined by 80% in Devon and is now absent from much of the county’s farmland. Lapwing numbers have fallen to below 100 breeding pairs on farmland in Devon.
- Ring ouzels are nearing extinction on Dartmoor.
- Devon holds 20% of the known UK marsh fritillary butterfly colonies. Although, once widely distributed throughout the UK, marsh fritillaries have declined substantially over the last 150 years. The butterfly has recently died out over most of eastern England and eastern Scotland. Despite a quite widespread distribution in south west England colonies are estimated to be disappearing at more than 10% a decade.
- The only remaining UK population of the rare cuckoo bee Nomada sexfasciata hangs on along a short stretch of the South Devon coast.
- England’s last remaining population of the narrow-headed ant (Formica exsecta) hangs on at a single site in Devon.
- A 99% decline has taken place in greater horseshoe bat populations throughout the UK over the last century. Devon remains one of its last strongholds.
- Freshwater pearl mussels on the rivers Taw and Torridge have not produced young for over 40 years – these represent the only remaining populations in the south of England.
