Rare birds appear as Wicken Fen's £1.8m peat restoration finishes
Rare wetland birds such as cranes and great egrets have appeared within hours of the completion of a peatland restoration project, according to the National Trust.The charity began restoring 590 acres (238 hectares) of lowland peat, a vital carbon store, at its oldest nature reserve, Wicken Fen in Cambridgeshire, a year ago. Peatland restoration project manager Ellis Selway said: "Seeing nature respond so quickly gives us real hope for the future of this landscape."The £1.8m works also revealed a significant archaeological discovery - a 5,000-year-old bog oak that archaeologists say is older than Stonehenge.
Mr Selway 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."
Peatlands, like those at Wicken Fen, store more carbon than all the world's forests combined, according to the National Trust. Part of the project focused on Burwell Fen, which had been reclaimed for agriculture during World War Two and was acquired in 2001.
Despite being drained and degraded, it included an area of deep peat where an extinct river once flowed. While a full fen habitat will take time to develop, other notable species that appeared shortly after Burwell Fen was re-wetted included spoonbill and wading birds such as curlew and a pair of little ringed plovers.
The ancient bog oak was unearthed from peat at Spinney Bank. Cambridge Archaeological Unit used tree-ring analysis to reveal it began growing 2,894 BC, lived for 222 years, and pre-dated the start of peat formation."Discovering a tree that took root nearly 5,000 years ago is a humbling reminder of how much history is preserved in these ancient landscapes," said Mr Selway.
However, a find initially believed to be a 17th Century cannonball from the English Civil Wars is more likely to have been a rollerball from a 19th Century wind pump.The trust said the project was its largest lowland peat restoration projectEmma Ormond-Bones, Wicken Fen general manager, said: "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."

National Star students take part in 24-hour wildlife survey
Students at a special educational needs college have teamed up with ecologists to find and identify the species found on their 80-acre Star College near Cheltenham in Gloucestershire took part in this week's "BioBlitz" with Gloucestershire Wildlife Trust to assess biodiversity on are now working on strategies to support nature and try to boost the numbers of vulnerable student said she had learned how small changes can make a big difference to wildlife. The students found that hedgehogs, rabbits, deer and foxes call the college's grounds home, as well as a huge variety of insects, including many Adamou, a community action officer with the wildlife trust, said the event aimed to give students autonomy to decide how best to help the species they found."My mission in Gloucester is to make sure everyone has the opportunity to do something for nature - to build a relationship, to take meaningful action, to do something that makes nature more important for them and therefore protect it," she said. "It's so easy to just say 'this habitat needs this, this is what needs to happen' - there's no co-ownership."Students spent the weeks leading up to the event learning to identify different species and also considering ways to help them, such as building hedgehog student, Isabella, said: "Hedgehogs are vulnerable to extinction and we need to look after them, but small changes can make a big difference."Elaine Hodgin, the college's sustainability lead, said staff and students were working to reduce the site's carbon footprint. "It's also about educating the learners about what they can do with regards to climate change," she Star now plans to hold the event annually.

David Hopkinson obituary
My friend and former colleague David Hopkinson, who has died aged 89, was director of the Medical Research Council's human biochemical genetics unit at University College London from 1976 until its closure in 2000. Hoppy, as he was universally known, had joined the unit at its inception in 1962 because in an earlier, more junior, position he had been one of the first medical scientists to describe molecular differences in human enzymes, long before DNA sequence differences were known about. The unit was established to research the extent and significance of genetic variation to human health. As its head, Hoppy expanded its focus to gene mapping and disease genetics while also moving into the new science of gene cloning and DNA sequencing. Born in Chesterfield, Derbyshire, to Albert Hopkinson, an iron and steelworks foreman, and Lilian (nee Siddal), a dressmaker, he went to Chesterfield grammar school, which fostered his early interest in organic chemistry. After completing a natural sciences degree at Cambridge University he qualified in medicine at the London hospital in 1959, working there until he joined the human biochemical genetics unit three years later. Hoppy was recruited by its inaugural head, Prof Harry Harris, becoming his right-hand man responsible for many of the unit's innovative experimental approaches, including developing novel methods of enzyme detection and electrophoresis. The unit moved in 1965 from its initial base at King's College to UCL, where I joined the unit three years later to study for a PhD under Harris. Hoppy remained there for the rest of his career. He published widely, and played an important part in teaching and supervision, being made full professor of London University in 1990. Twenty five years after his retirement, his role as mentor is remembered with great warmth by his former staff and students. Hoppy read widely and appreciated drama and music. A practical man who took pleasure in manual labour, he was an accomplished gardener and delighted in propagating plants and growing vegetables. He also enjoyed summers hiking in the Swiss Alps, and was a keen birdwatcher. In retirement, he studied architecture and German, and gained a first-class degree in geology at the Open University. He also spent many years as a volunteer at Chilterns' Citizens Advice in Chesham, Buckinghamshire. He is survived by his second wife, Prof Yvonne Edwards, and by three children, Paul, Susan and Ian, from his first marriage, to Josephine (nee Manze), which ended in divorce, and four grandchildren.

The Guardian view on Our Story With David Attenborough and The Herds: a new theatre of the Anthropocene
As parts of the UK swelter, this week brought yet more alarming reports of increasing temperatures, extreme weather events and dwindling chances of meeting the global 1.5C target. It was the UK's warmest spring on record and its driest in more than 50 years. Communicating the urgency of our predicament without provoking despair and hopelessness is an intractable challenge, especially when it comes to children. But two trail-blazing theatre experiences are bringing the breakdown of the natural world into urban metropolises, and raising the alarm with such immediacy that even those of us fortunate enough to live in places that have so far been relatively unaffected by the climate crisis must pay attention. Our Story With David Attenborough is a breathtaking 50-minute immersive history of the planet, from the team behind the recent film Ocean. Thanks to 24 projectors and 50 speakers, the Natural History Museum's Jerwood Gallery is transformed into the solar system, prehistoric caves, the ocean and the jungle. As in Maurice Sendak's children's classic Where the Wild Things Are, 'the walls [become] the world all around'. We swim with whales and come face to face with gorillas – as Sir David did in Life on Earth in 1979. We look from space: like last year's Booker prize-winning novel, Orbital, by Samantha Harvey, Our Story inspires the feelings of awe and protectiveness towards our planet that astronauts call 'the overview effect'. In the past, Sir David has been accused of not speaking out strongly enough on human-made ecological disaster. But the Guardian writer George Monbiot, once one of his fiercest critics, described Ocean, released for Sir David's 99th birthday this year, as the film 'I've been waiting for all my working life'. In Our Story, we journey through mass extinctions of the past and, speculatively, in the future. Without change, 'the prospect for the generations that follow is grim', the audience is warned. Next Friday, hundreds of lifesize elephants, giraffes, gazelles and animal puppets of all kinds will stampede through London's streets on their 20,000km journey from central Africa to the Arctic Circle. The Herds is the follow-up project to The Walk. In 2021, a 12-foot puppet girl, Little Amal, travelled from the Turkey-Syria border to London, to raise awareness of the refugee crisis. Little Amal reached 2 million people in 17 countries. Now her creators hope to do the same for the climate emergency. As the herd flees north, it will be joined by puppets of native species from each country it visits. Manchester is its next destination, before continuing on to Scandinavia. The project's artistic director, Amir Nizar Zuabi, has acknowledged that all such endeavours, however ambitious, are just 'water dripping on a stone'. But, as he says, over time enough drips can reshape a stone. These are visceral, sensory immersions. Like Olafur Eliasson's climate art installation The Weather Project at Tate Modern in 2003, such spectaculars invite us to reflect together – they are collective experiences. This is the theatre of the Anthropocene: vast, cataclysmic, beautiful and yet ultimately hopeful as well. They help us visualise what a different world might look like – if only politicians and corporations were made to act. The next chapter is up to us. As Sir David says at the end of Our Story, we must work towards a time when Earth becomes a planet 'with not only an intelligent species, but a wise one too'.
