ONE of Scotland’s rarest breeding ducks looks set to benefit from specially constructed floating nesting rafts manufactured by Fusion Marine. In the UK, common scoters (Melanitta nigra) breed in only a handful of freshwater lochs in the northern Highlands and it is hoped that the supply of these two nesting rafts will provide safe new breeding sites. The common scoter is on the Red List as a bird of high conservation concern, with only about 50 breeding pairs in the UK. Working with the RSPB and Forestry Commission Scotland (FCS), Fusion Marine designed and manufactured the 7m by 3.75m rafts, made from durable polyethylene and recycled plastic sourced from redundant fish farm pens. Peat, turf and heather are placed on top of the rafts so as to create natural looking floating islands that will prove attractive for nesting and which are also safe from predators such as mink. The rafts will be sited on two lochs where scoters are known to breed. It is envisaged that the rafts will also enable researchers to better monitor scoter breeding behaviour, which will enhance knowledge of their requirements and aid conservation efforts. The project consortium is made up of the FCS, Scottish Natural Heritage (SNH), Wildfowl and Wetlands Trust, Scottish and Southern Energy (SSE), Blue Energy, the Ness and Beauly Fisheries Trust, the RSPB and Marine Harvest. Kenneth Knott of FCS said: ‘I am delighted that Fusion Marine took the challenge of helping the project develop and build a larger ‘island’ for use in the project. This was a critical part of completing the jigsaw to take the project forward. ‘The research showed that the problems associated with the scoters rearing their ducklings could be addressed, at least in part, by this new style of artificial island. ‘The more robust construction includes extra flotation allowing for a deep habitat layer to be supported on the island without fear of sinking. ‘We were pleased with the support from Marine Harvest in providing materials and from our two principal sponsors, SSE and Blue Energy, who have assisted with the finance, but principally to Fusion Marine for making ideas turn into reality.’ Corrina Mertens, operations officer for SNH in Lochaber, said: ‘This initiative is a tremendous example of how a partnership of organisations from all walks of life can work together for the benefit of the natural heritage and we would like to express our gratitude to everyone who is involved. ‘We very much hope that this experiment will yield the result needed to ensure the future survival of the common scoter in this part of Scotland.’ Rhuaraidh Edwards of Oban based Fusion Marine said: ‘We have previously used our experience in polyethylene technology to manufacture rafts for nesting terns, which proved very successful. ‘It is great that we have now been able to use such knowledge to help secure the future of one of Scotland’s rarest breeding ducks.’

More than a quarter of UK birds, including the puffin, nightingale and curlew, require urgent conservation efforts to ensure their survival, according to a new report on the state of the UK’s birds. Since the last review in 2009, an additional 15 species of bird have been placed on the “red list”, a category that indicates a species is in danger of extinction or that has experienced significant decline in population or habitat in recent years. The total number of species on the red list is now 67 out of a total of 247. On top of this, eight species are considered at risk of global extinction: the balearic shearwater, aquatic warbler, common pochard, long-tailed duck, velvet scoter, slavonian grebe, puffin and turtle dove. “We’ve been putting these reports out since 1999 – I think it is one of the worst we’ve seen,” said David Noble, one of the authors of the State of the UK’s Birds study and principal ecologist for monitoring at the British Trust for Ornithology (BTO). Noble said a variety of factors led to the classification of an increased number of species in danger, including land use change, such as afforestation and drainage of fields for farmland, and increased numbers of predators, such as foxes. He also pointed to the global impacts of climate change, which affect migratory birds. The report is produced by the Royal Society for the Protection of Birds (RSPB), the BTO and the Wildfowl and Wetlands Trust, in partnership with the UK’s statutory nature conservation bodies. It collates material from other studies and bird surveys to give a thorough report on the status of various avian species. There is particular concern among conservationists for the curlew, Europe’s largest wader, which has seen a population decline of 64% from 1970 to 2014 in the UK, largely due to habitat loss. The UK supports up to 27% of the global curlew population, and due to its “near threatened” global status, a research plan has been created to help understand the causes of the species’ decline. “Curlews are instantly recognisable on winter estuaries or summer moors by their striking long, curved beak, long legs and evocative call,” said Dr Daniel Hayhow, conservation scientist at the RSPB. “They are one of our most charismatic birds and also one of our most important.” There was good news in the report for some species, including the golden eagle, whose numbers have increased 15% since 2003, and for cirl buntings, which now have more than 1,000 breeding pairs, up from 118 in 1989. Another success story is the red kite, once one of the UK’s most threatened species, which is now on the green list – the lowest level of concern – after years of efforts by conservationists. Noble said the improvement in the red kite and golden eagle population had to do with a slow rebuilding of populations that had been decimated by attacks from people keen to protect their grouse moors and egg collectors taking their eggs. In the case of the red kite, he said monitoring of nest sites and the reintroduction of the birds into new areas of the UK were reasons for the recovery of the species. “Now they’ve spread right across the UK from the strongholds they were reduced to in Wales and some parts of Scotland. Now you can see them in East Anglia occasionally,” he said. In addition to these successes, a number of species, such as the bittern and nightjar, have moved from the red list to the amber list. Species are placed on the amber list if they are considered at threat of European extinction or have seen a moderate decline in population or habitat. An additional 22 species have moved from the amber to the green list.

Businesses routinely use internet data to learn about customers and increase profits - and similar techniques could be used to boost conservation. New research has tracked public interest in conservation over time, and found sudden spikes in interest linked to media coverage and seasonal events. Peaks in interest in certain animals - such as when a species appears on TV programmes like the BBC's Planet Earth II - could be harnessed to aid protection efforts, the researchers say. "Using these methods is relatively cheap and they produce huge sample sizes to tell us what people think about conservation," said lead author Andrea Soriano-Redondo, of the Centre for Ecology and Conservation on the University of Exeter's Penryn Campus in Cornwall. "Up until now people have relied on surveys, which are extremely useful but very expensive, take a long time and usually have relatively small sample sizes." The research, by the University of Exeter, the Wildfowl and Wetlands Trust and the Royal Society for the Protection of Birds, is published in the journal Biological Conservation. Ms Soriano-Redondo, a PhD student, noted spikes in interest in cranes after a media release in August 2015 that detailed the first successful breeding of Eurasian cranes in south-west England in over 400 years - but she said the level of interest went "back to the baseline" soon afterwards. The same happened for sloths and iguanas after they appeared on Planet Earth II. "The challenge is to make the most of these surges and keep that going after the initial peak," she said. "At the moment the power of this public interest isn't being used to its full potential to promote conservation." The study noted peaks in interest in bird species such as red kites and cranes when each species was nesting. The researchers used both offsite tools (such as Google Trends) and onsite tools (such as Google Analytics) to monitor public interest in conservation. Ms Soriano-Redondo's PhD studies are part of the Great Crane Project, which has reintroduced cranes to the South West in order to restore a healthy population of wild cranes in the UK.

Climate change is already wrecking some of Britain’s most significant sites, from Wordsworth’s gardens in Cumbria to the white cliffs on England’s south coast, according to a new report. Floods and erosion are damaging historic places, while warmer temperatures are seeing salmon vanishing from famous rivers and birds no longer visiting important wetlands. The report was produced by climate experts at Leeds University and the Climate Coalition, a group of 130 organisations including the RSPB, National Trust, WWF and the Women’s Institute. “Climate change often seems like a distant existential threat [but] this report shows it is already impacting upon some of our most treasured and special places around the UK,” said Prof Piers Forster of Leeds University. “It is clear our winters are generally getting warmer and wetter, storms are increasing in intensity and rainfall is becoming heavier. Climate change is not only coming home – it has arrived,” Forster said. It is also already affecting everyday places such as churches, sports grounds, farms and beaches, he said. Wordsworth House and Garden in Cockermouth, where the romantic poet William Wordsworth was born in 1770 and learned his love of nature, was seriously damaged by two recent flooding events linked to a changing climate. In November 2009, torrential rain caused £500,000 of damage, sweeping away gates and walls that had survived since the 1690s. Floods inundated the site again during Storm Desmond in December 2015. “When I saw the damage the floods had caused in 2009 I was shocked and it took almost three years to repair the garden,” said the house’s head gardener, Amanda Thackeray. “Then after all that hard work to see the devastation from flooding in 2015 was very upsetting.” A century-long record shows the UK is experiencing more intense heavy rainfall during winter. Researchers can also use climate models to reveal the influence of global warming on some extreme events and have found the UK’s record December rainfall in 2015 was made 50-75% more likely by climate change. Another study found Storm Desmond was 40% more likely to have occurred because of the human activities that release greenhouse gases, such as burning fossil fuels. Birling Gap is part of the world famous Seven Sisters chalk cliffs on England’s south coast and over the last 50 years, about 67cm of cliff is eroded each year. But during the winter storms of 2013-2014, the equivalent of seven years of erosion occurred in just two months. “The succession of storms provided a stark warning that coastal ‘defence’ as the only response to managing coastal change looks increasingly less plausible,” said Phil Dyke, coastal adviser at the National Trust. “We must learn how to adapt.” Existing buildings at Birling Gap are being lost and new buildings will be designed to be easier to move back as the cliff disappears. Scientists know that climate change is driving up sea levels and increasing the likelihood of more intense storms, meaning the rate of erosion is likely to rise. Rising temperatures are also affecting wildlife, including in the famous salmon rivers, the Wye and Usk, where otters and kingfishers also live. December is peak spawning time for salmon in Wales, but recent winters have been exceptionally warm. “After eliminating other potential causes such as disease and lack of adults, we have come to the conclusion that the exceptionally high water temperatures of November and December 2016 are the reason for the disastrous salmon fry numbers this year,” said Simon Evans, chief executive of the Wye & Usk Foundation. 2015 was little better, with young salmon found at just 17 sites out of 142, when they usually would be expected at 108 areas. Research has shown salmon populations across the Wye catchment fell by 50% from 1985-2004, despite cuts in water pollution. But stream temperatures have risen by up to 1C in that time, leaving researchers to conclude that climate change is a key factor in plummeting salmon numbers. Slimbridge wetlands in Gloucestershire is one of the UK’s most important bird sites, hosting 200 species from all over the world, but is also seeing changes as the climate warms. Numbers of migratory white-fronted geese have fallen by 98% in the last 30 years due to warmer weather further north. Geoff Hilton, at the Wildfowl and Wetlands Trust said the shrinking flocks could have knock-on effects on the wetland habitat: “These are quite big changes ecologically. If you suddenly lose thousands of geese from a wetland, there are bound to be big effects on that wetland.” Warmer conditions have also meant water primrose, an alien invader to the UK, has grown aggressively in wide, dense mats and is seriously damaging native plants and fish. However, warmer winters have seen little egret numbers visiting Slimbridge increasing from just eight in the 1990s to 30 in 2013. Other sites being ruined by climate change, according to the new report, include a famous riverside pub on Manchester’s river Irwell, the Mark Addy, which has not re-opened after the 2015 winter floods and the historic clubhouse at Corbridge cricket club in Northumberland, now demolished after the same floods. The report also warns that the 5,000-year-old neolithic village at Skara Brae on Orkney, revealed after a great storm in 1850 stripped away grass and sand, could be destroyed in future as violent storms become more common.

The government's long-delayed 25-year plan for improving nature in England should be published immediately, MPs have said in a letter to the Environment Secretary Andrea Leadsom. They asked her to explain why the strategy due in 2016 is still not out. They say it's essential that ministers have agreed and published a clear plan before negotiations on Brexit begin. The government promised in its manifesto that it would leave nature in a better state than it was inherited. The all-encompassing masterplan aims to set out a policy framework for air, freshwater, marine, wildlife, soils, flooding, forests, and even the urban environment. Environment charities which have been briefed on the plan say it is appropriately ambitious in some respects - but they, too, want to see it in black and white. The plan was originally due to be published in summer last year. I understand that the document has been signed off by the Prime Minister but has been delayed for weeks, waiting for the ideal time to publish. The letter of complaint to government has been signed by all the members of the Environment Audit Committee, which involves Conservative, Labour and Green MPs. The Lib Dems told BBC News they supported the demand. Their letter says: "We welcome this important step by the government to take a longer-term approach to protecting our environment. However, we are disappointed by the continuing delays in publication of the framework. "First, the framework (of the plan) was delayed from summer last year to the autumn following the referendum. We are now in March, the framework has still not been published and there is no indication of when it will be." The letter accepts that Defra has been under strain from preparations to leave the EU, on top of budget cuts. But it says: "The Plan should be published and consulted on before Article 50 is triggered, so as to inform the government's negotiating position. "This seems unlikely, raising the prospect of the government entering crucial and time-limited negotiations with the EU without an agreed plan. It is essential that the 25-year plan is not delayed further." Members are particularly concerned about post-Brexit policy on farming, which will have a huge impact on wildlife, water and air pollution, soil loss and flooding. They want assurances that when the UK is no longer under the jurisdiction of the Commission and the European courts, the government will still be able to be held to account if it fails with its environmental promises The government is preparing a separate but related plan for post-Brexit farming. I understand this is also finished and approved but awaiting a "suitable" publication date. Peter Morris from the Wildfowl and Wetlands Trust told BBC News: "We're hoping for a legally-binding plan, with milestones for a healthy environment, the money to invest in our natural world, and clear monitoring to make sure it succeeds. This should be backed up with a commitment for a new Environment Act to establish the plan in law." A spokesman for the government told BBC News it would publish both plans as soon as possible. The government wants to leave Nature in a better state: here's three examples of how that can be done. Carbon stores: Peat bogs are good for wildlife and flood prevention - and for storing carbon (they store 10 times as much as England's forests, say the Wildlife Trusts). Yet 80% of the UK's bogs are damaged or lost. On the western edge of Salford, conservationists are cultivating sphagnum moss in polytunnels to re-colonise the devastated landscape. Suffolk hedgerows: Hedges are a rich habitat and a haven for pollinators but over 100,000 km are estimated to have been lost between 1984 and 1990 alone. In Suffolk one farmer, Steve Honeywood, has seen bird numbers treble and species increase from 60 to nearly 90 by measures including pruning just one edge of his hedges each year and leaving two uncut edges for wildlife. He's now planting elm hedges to support the elusive white-letter hairstreak butterfly. Urban wildlife: In South London, locals are working to create green areas along the catchment of the lost River Effra, which was turned into a closed sewer in Victorian times. By smashing up concrete and tarmac they want to extend flood resilience and improve neighbourhoods for people and wildlife. The government wants to extend people's contact with nature.

The UK has sovereignty over 16 Overseas Territories, which hold some of the world's great seabird colonies and collectively support more endemic and globally threatened bird species than the whole of mainland Europe. Invasive alien mammalian predators have spread throughout most of the Territories, primarily since European expansion in the 16th century. Here we review and synthesize the scale of their impacts, historical and current, actions to reduce and reverse these impacts, and priorities for conservation. Mammalian predators have caused a catastrophic wave of extinctions and reductions in seabird colony size that mark the UKOTs as a major centre of global extinction. Mammal-induced declines of threatened endemics and seabird colonies continue, with four Critically Endangered endemics on Gough Island (Tristan da Cunha), St Helena and Montserrat directly threatened by invasive alien House Mice Mus musculus, Feral Cats Felis catus and rats Rattus spp. Action to reduce these threats and restore islands has been modest in comparison with other developed countries, although some notable successes have occurred and a large number of ambitious eradication and conservation plans are in preparation. Priority islands for conservation action against mammalian predators include Gough (which according to one published prioritization scheme is the highest-ranked island in the world for mammal eradication), St Helena and Montserrat, but also on Tristan da Cunha, Pitcairn and the Falkland Islands. Technical, financial and political will is required to push forward and fund the eradication of invasive mammalian predators on these islands, which would significantly reduce extinction risk for a number of globally threatened species. © 2010 The Authors.

Almost 70 years ago to the day Peter Scott – son of Antarctic explorer Captain Scott – opened Slimbridge, the first of nine Wildfowl and Wetlands Trust (WWT) centres across the UK. There are now WWT centres all over the country, with Caerlaverock, in Dumfries, Castle Espie, in Northern Ireland, Welney, in Norfolk and Llanelli in South Wales just some of the better known. We would like to see your pictures and hear your stories if you have visited wetlands in the UK – whether they are part of the WWT network or otherwise. Perhaps you have photographs of rare birds you are proud of or have spotted other wildlife worth getting the camera out for? Do you you live near a wetland, or plan holidays or day trips around visiting them? Maybe you take time out to walk around a wetland in the city, such as the Woodberry Wetlands, recently opened by Sir David Attenborough, or the London Wetland Centre. Share your pictures from visits during all seasons, and tell us a little about them including where they were taken and when, by clicking the blue GuardianWitness buttons on this article or, if they are not appearing on your device by clicking here. We’ll compile an online gallery from some of our favourites. You can also use the Guardian app and search for ‘GuardianWitness assignments’ – if you add it to the homepage you can keep up with all our assignments.

Winter blast on its way as first Siberian swans arrive at Slimbridge The first migrating Siberian swans landed in Britain – heralding the belated arrival of winter. Each year around 300 Bewick swans flock to the Wildfowl and Wetlands Trust reserve at Slimbridge, Glos after flying 2,500 from Arctic Russia. This year’s arrival – coinciding with the first cold snap of the season – is the latest for 45 years and more than two weeks later than usual. It traditionally marks the beginning of winter as the birds head to Britain to escape the Arctic weather which follow closely behind them. The first family of two adults and two cygnets touched down at 7.15 on Thursday morning (06/11/14). The adults were identified as regulars Nurton and Nusa who have been coming to the spot for the last five years. Slimbridge swan expert Julia Newth said: “This is the latest arrival date since 1969. “It is no coincidence that their arrival has coincided with a change from the mild temperatures and south-westerly head winds that have dominated in recent weeks. “We are excited to see that the first arrivals are a family because the swans desperately need more cygnets to bolster the dwindling population. “Swan volunteer Steve Heaven quickly identified the adult pair from their distinct bill patterns as regular WWT Slimbridge visitors Nurton and Nusa. “They are familiar with the reserve as they have spent the last five winters here. “Their cygnets have now learnt the migration route from their parents and we are hoping that they will also become regular fixtures here. “At the daily Wild Bird Feeds at WWT Slimbridge we really enjoy pointing out the swan families to visitors as they have such interesting histories and interactions on the lake.” The Bewicks – the smallest and rarest members of the swan family – live in Siberia during the summer. In winter they migrate west – aided by chilling easterly winds – to escape winter temperatures of -25 degrees C. They normally arrive at Slimbridge in a steady stream between October and January. Bewick’s have migrated to Slimbridge every winter for 60 years and adult swans teach their young the route. Their arrival comes after weather experts predicted the harshest winter in 100 years. James Madden, forecaster for Exacta Weather, said last week: “The worst case and more plausible scenario could bring something on a similar par to the winter of 2009/10. “That was the coldest in 31 years, or an event close to 2010/11 which experienced the coldest December in 100 years.”

We estimate potential risks to human health in the UK from dietary exposure to lead from wild gamebirds killed by shooting. The main source of exposure to lead in Europe is now dietary. We used data on lead concentrations in UK gamebirds, from which gunshot had been removed following cooking to simulate human exposure to lead. We used UK food consumption and lead concentration data to evaluate the number of gamebird meals consumed weekly that would be expected, based upon published studies, to result in changes, over and above those resulting from exposure to lead in the base diet, in intelligence quotient (IQ), Systolic Blood Pressure and chronic kidney disease (CKD) considered in a recent opinion of the European Food Safety Authority (EFSA) to be significant at a population level and also in SAT test scores and in rates of spontaneous abortion. We found the consumption of <1 meal of game a week may be associated with a one point reduction in IQ in children and 1.2-6.5 gamebird meals per week may be associated with the other effects. These results should help to inform the development of appropriate responses to the risks from ingesting lead from ammunition in game in the UK and European Union (EU). © 2012 Elsevier Ltd.
