National Trust's largest lowland peat restoration a ‘powerful step forward'
Wicken Fen in Cambridgeshire, which has been looked after by the conservation charity since 1899, has undergone six months of various works to help secure its future.
One task was installing a waterproof liner along 300 metres of a perimeter boundary where water had been escaping, helping to retain moisture in the peat and lock carbon in the soil.
The overall scheme spanned 590 acres of lowland peat.

Emma Ormond-Bones, general manager at Wicken Fen, said: 'Nature is declining at an alarming rate, and the climate crisis is placing unprecedented pressure on the places and species we care about.
'This project is a huge achievement for the National Trust and a powerful step forward in the restoration of our natural world.
'It's providing the space and conditions nature needs to recover, while also helping to store carbon and make landscapes more resilient to future environmental challenges.'
Another part of the project focused on Burwell Fen, which was reclaimed for agriculture during the Second World War and acquired by the National Trust in 2001.
A clay bund was constructed and the fen was re-wetted, with rare wetland birds such as cranes and great egrets appearing within hours of the water level being raised.
Ellis Selway, peatland restoration project manager, said: 'Watching cranes arrive so soon after we raised the water was a moment I won't forget.
'It made all the effort and planning worthwhile.
'These birds are a sign that wetland life is returning, and fast.
'Seeing nature respond so quickly gives us real hope for the future of this landscape.'
New solar-powered pumps are now helping to manage water levels sustainably.

The restoration works also unearthed a bog oak which was then dated by the Cambridge Archaeological Unit using tree-ring analysis.
The results show the oak began growing in 2,894 BC and lived for 222 years, pre-dating the start of peat formation.
The National Trust said the find was older than the stones at Stonehenge.
Mark Knight, from Cambridge Archaeological Unit, said: 'This discovery exemplifies that wonderful relationship between depth and time, which comes with exploring the peat fen.
'Traces of past landscapes abound beneath its surface, and what's more, they come beautifully preserved and in clear chronological order.'

A look at the moon ahead of the lowest full moon of the year
That in itself is nothing unusual, but this particular full moon is generating quite a bit of interest by being the lowest full moon of the year as well as one of the furthest from the sun. Every year, the full moon is at its minimum altitude above the horizon in June. This is because it lies opposite to the sun, which, by contrast, is at its highest point this month as we approach the summer solstice. Because the moon's orbit is slightly tilted, it doesn't quite follow the same path as the sun and planets, that path being referred to as the ecliptic. The moon wanders slightly, travelling above and below the ecliptic, and this Tuesday reaches a point when it will be at its furthest southerly point, something that occurs every 18.6 years. This means that June's full moon will be at a point astronomers refer to as a 'lunar standstill' or 'lunistice'. The next time this will occur is June 2043. This all means that on Tuesday evening the moon will rise at around 9.30pm, but not achieve any great altitude, literally skimming the south-east horizon. Aside from the moon appearing very low in the sky and hardly climbing at all, the position where the moon rises and eventually sets will also be the closest points possible, rising in the southeast, then setting in the southwest. There's also the fact that this full moon is one of the most distant too, about 94,600 miles from the sun. For comparison, the average is around 93,200 miles. June's full moon, also referred to as the Strawberry Moon, given the ripening of the fruit at this time of year, will also be shining, (reflected sunlight), through the thickest layer of the Earth's atmosphere possible and may well appear golden in colour, perhaps orange, or even red. This is all down to the scattering of light to allow for longer wavelengths of colour to show through, like yellows and oranges. You may have noticed that when the moon is low down on the horizon it actually seems bigger than when it's high up in the sky? Well, in fact, it's not; it's a trick of the mind known as the 'moon illusion'. Photographs prove that there is no real difference in size between the moon when it is positioned low on the horizon or when high up in the sky, but this is not what we see, with an optical illusion created by how our brains absorb visual information. The illusion has baffled minds down the centuries with records of the seemingly enlarged Moon dating back to 4th century BC. Whilst there is no solid scientific explanation for the 'moon illusion', in reality, the moon's distance really doesn't change all that much, no matter where it is positioned in the sky. The International Space Station continues to have a rest from being on view in our skies. Send your astrophotography pictures to: thenightsky@

Yorkshire Dales project helping to save rare orchid from extinction
A project to bring back one of the UK's rarest wildflowers has shown its first signs of success, experts lady's slipper orchid was thought to be extinct by the early 20th Century, until a single plant was discovered in a remote area of the Yorkshire Dales in location was kept secret, with volunteers providing round-the-clock monitoring over several decades to prevent the plant being dug up and stolen.A scheme was launched two years ago to plant hand-reared orchids, with a plant discovered last June the first to germinate "of its own accord" since 1930, according to the Yorkshire Wildlife Trust (YWT). "The lady's slipper is a real icon of limestone habitats," Jonathan Leadley, from YWT, explained. "Where we've got limestone geology there's often a wealth of wildlife, but we've lost so much of the wildlife from these habitats."This is a real flagship, like a superstar."Efforts to boost the population began in the 1990s, with a plea for help that resulted in a small number of privately-owned, wild-sourced orchids being offered as part of a captive breeding were reintroduced to locations in the north of England - which were also kept secret to avoid the ongoing threat of theft - with the project led by YWT since were propagated in Kew Gardens' laboratory, with young plants then nurtured by a network of volunteer specialists managed by the National Trust. Mike Fay, Kew senior research leader, said it had been a "flagship" conservation scheme for many years."The appearance of a seedling is incredibly exciting and offers us hope," he Walker, from the Botanical Society of Britain and Ireland, paid tribute to the "hundreds of volunteers and enthusiasts who have carefully nurtured [the plant] back into the wild". Mr Leadley said that while "only a minority of people" stole plants, it was "certainly" still a threat."When all this effort is being put in by lots of people to try and bring a species back from the brink of extinction, we really don't want all of that effort to go to waste by a selfish individual pinching that plant," he said."We've got to keep it guarded for now, but hopefully at some point in the future there'll be so many of these plants out there that everybody will be able to enjoy them."

Farne Island 'puffin cam' attracts thousands of viewers
A webcam allowing people to spy on puffins has garnered tens of thousands of National Trust has set up cameras near puffin burrows and clifftops on the Farne Islands, off the coast of ranger James Porteus said viewers were "loving it" and that it was helping to end unequal access to said people were able to witness some "really amazing behaviour up close" and told viewers to keep an eye out for pufflings - baby puffins - leaving their burrows at dusk, previously rarely seen as visiting hours on the remote islands are restricted. The Farne Islands are a National Nature Reserve in England and an internationally important home to approximately 200,000 Porteus said viewers had seen puffins bringing fish into their burrows, opportunistic gulls trying to steal the catch, and "amazing sunsets" on the north-west facing camera."There's always something to watch," he said. Puffins have been facing growing threats including climate change, Mr Porteus said."They're a species that need our help," he manager for the Northumberland coast Daniel Wilson said the cameras were solar battery powered and look like a blended piece of were set up to capture the 2025 breeding season and were installed just before the first seabirds Wilson, who has been with the trust for about 20 years, said seeing the huge team project come to fruition was "incredibly rewarding".In the first three weeks of operation, the main puffin camera reached 90,700 views and the average watch-time is about five was an average of 25 people watching at any one time, the National Trust team said it intended to keep the stream going until at least the end of June.
