How native breeds 'restore and protect' landscapes
Reintroducing native grazing breeds to landscapes can have multiple benefits, including reducing the risk of wildfires, according to Derbyshire Wildlife Trust.Ten Highland cattle and eight Exmoor ponies are being introduced to the Trent Valley in Derbyshire as part of a rewilding project intended to restore habitats and increase biodiversity.The hope is their behaviour will mimic that of their ancestors, such as aurochs, elk and wild horses, creating so-called "mosaic landscapes" where wildlife can thrive.While the area has not been affected by recent wildfires, the trust says the animals' grazing habits can help create natural fire breaks in places more at risk.
The project has been kickstarted with almost £330,000 in funding from the National Highways "Network for Nature" programme.
Wilder grazing assistant Alex Fisher works alongside 11 trained volunteers to acclimatise the new additions to their handlers before they are allowed to roam free. It has taken almost a year for the Exmoor ponies to become comfortable with approaching humans.Mr Fisher says he has to tread a fine line between getting the animals accustomed to being handled, while making sure they remain self-sufficient."These are the perfect lawnmowers," he says. "They know exactly which type of vegetation to eat and graze from."As an example, he points out that their current field is still covered in buttercups, which the ponies dislike.Unlike domesticated cattle, they nibble the grass short while leaving the roots and soil intact. And they benefit nature from both ends."We don't give them any medication or supplementary feed," Mr Fisher says. "That would come through in their faeces and kill small insects like the dung beetle, which can help heal nature."The ponies had no problem coping with snow on the ground last winter."They used the hooves to pull back the snow and graze the vegetation. We were really happy with how they were over winter."
Derbyshire Wildlife Trust's Living Landscape Officer Katie Last watched this year's record-breaking wildfires with dismay.She agrees with Met Office scientists who say the changing climate is increasing the risk of fires, and says restoring landscapes with the aid of native breeds can help."Large grazing herbivores can help create a resilient landscape to wildfires," she says."The trampling and the grazing of vegetation will remove the existing fuel for the fires, and also [it] creates those open gaps and areas of bare ground that will stop the spread of wildfires."But she says that is just one of the many benefits we gain from introducing large herbivores as part of rewilding projects."The way that they manage our grasslands, they're much better at capturing carbon in the ground. They don't overgraze, which gives the soil time to regenerate."Ms Last says because the cattle and ponies graze at different levels, they also remove vegetation and encourage regrowth, which in turn keeps more carbon in the soil.
Ecosystem engineers
In the past the cattle and ponies would have moved naturally through landscapes as they were hunted by predators such as lynx and wolves.Now the Trust uses GPS collars and geo-fencing to train the Highland cattle and keep them moving."We'd like to see our grazing expanded across the whole of Derbyshire," says Ms Last. "[These breeds] are ecosystem engineers. They create fantastic, diverse mosaic habitat which boosts wildlife and creates a resilient eco-system overall."The project is part of wider moves by Wildlife Trusts to reintroduce missing species to benefit nature.

The Guardian view on fitness: evidence of the benefits of exercise keeps growing, but who is listening?
The role of exercise in promoting good general health, and helping to prevent heart disease, strokes and diabetes is well established. No wonder, then, that long‑distance running keeps growing in popularity. Popular tracks and parks have never been busier, with groups in stretchy Lycra and fitness trackers on their wrists. The internet is awash with exercise videos, while figures earlier this year showed that gym memberships have climbed to a record 11.5m. The 16.9% of people aged 16 or over in Britain who belong to a gym is one of the highest proportions in Europe. The older teenagers and young adults of generation Z are a key demographic behind this social trend. And recent news from the world's biggest cancer conference, in Chicago, shows how right they are to take the health benefits of fitness seriously. A landmark trial compared the outcomes of patients in several countries who were placed on a programme of structured exercise – assisted by a personal trainer – with those offered standard health advice. The results showing that exercise could be as effective as drugs, without the side-effects, in preventing the recurrence of colon cancer, were described by Prof Sir Stephen Powis, the national medical director of NHS England, as 'really exciting'. The expectation is that the study will influence treatment guidelines worldwide – including in the increasingly fitness-conscious UK. But there is another narrative about exercise in Britain that is hard to reconcile with the one above. This is that we are a chronically unwell, overweight and sedentary population, whose health problems are only partly linked to the Europe-wide demographic challenge of ageing. These difficulties are widely recognised to be psychological as well as physical, with particular concerns around the worsening mental health of children and young people, which is widely linked to the rise in smartphone use. Which of these accounts of British fitness habits is more accurate depends which segment of the population is being scrutinised. Government figures show that the age gap – with 16- to 24-year-olds the most physically active age group – is not the only one. There is also a significant socioeconomic disparity. Students and adults in managerial and professional jobs are much more likely to keep active than manual workers or people who are long-term unemployed. As with other indicators of health, such as weight or smoking, there is a clear correlation with income. Richer people with more education and higher social status are more likely to be well. Could gen Z buck this trend with its more general embrace of fitness, which some point out is far cheaper than pub-going? It is too soon to be sure. Some young people believe their gym-going habits are as much about economic insecurity and status anxiety as they are about commitment to health. But as ministers finalise their 10-year plan for the NHS, which is expected to place a strong emphasis on prevention, they have an opportunity to build on, and shape, the way that exercise is offered and experienced. That being physically active is good for you is reinforced by the latest cancer study. But a preoccupation with personal appearance can be debilitating. A public health approach to exercise should seek to maximise the gains and minimise the harms associated with fitness culture.

Nottingham attack families ask Streeting for names of staff who treated killer
The families of the Nottingham attack victims said they have told the Health Secretary they want the names of staff involved in treating killer Valdo Calocane to be made public. A February report into the care received by Calocane detailed how he was not forced to have long-lasting antipsychotic medication because he did not like needles, and how other patients at Nottinghamshire Healthcare NHS Foundation Trust also went on to commit 'extremely serious' acts of violence. The relatives of 19-year-old students Grace O'Malley-Kumar and Barnaby Webber, and 65-year-old caretaker Ian Coates, met with Wes Streeting on Monday and asked for those responsible to be held accountable. After the meeting, Dr Sanjoy Kumar, Grace's father, said: 'It was the actions of a few people that put a dangerous man out in the community'. Calocane, who had been diagnosed with paranoid schizophrenia, killed three people and attempted to kill three more in Nottingham in June 2023. He was sentenced to an indefinite hospital order in January 2024 after admitting manslaughter by diminished responsibility and attempted murder. Calocane was admitted to hospital and sectioned under the Mental Health Act four times between 2020 and 2022 because of his violent behaviour and refusal to take his medication, before NHS services lost track of him and discharged him in the months before the attacks. Three reports: including one by the Care Quality Commission (CQC); described failings in his care but none included practitioners' names, Dr Kumar said with copies of the documents in-hand. Speaking outside the Department for Health and Social Care (DHSC), he told reporters: 'We'd like to know who was involved in the care of this person who committed all this harm. Why aren't there any names? 'He was sectioned four times – was it four different consultants? Was it one consultant? Who were the teams who didn't do their jobs?' He said: 'I think we deserve to know the detail – everyone in the country who has suffered the way we have through mental health-related homicide deserves to have the detail. 'When an operation goes wrong, someone gets named.' Dr Kumar added: 'We want people to just know, if they did wrong, what is it they need to do to be put right? Whether it's retraining, whether it's … doing the professional development again. 'The point is that you just can't have people who are providing a risky service even now.' He added that the Health Secretary was 'very much on our side, he very much wants to see a way through' and that Mr Streeting has promised 'he's going to work hard at it'. Prior to the meeting, the families said in a statement that their correspondence with the mental health trust's chief executive, Ifti Majid, had been 'light on detail, vague, evasive, defensive and contradictory'. They added that he failed to answer Dr Kumar's questions. Dr Kumar said he has given Mr Streeting the questions he put to the chief executive. He said the Health Secretary 'has promised to do his best to get us all the answers', adding that he has confidence in Mr Streeting because he has 'taken a personal interest in this case' and likewise 'wants to end homicide by mental health'. Their meeting also follows a complaint lodged with the Independent Office for Police Conduct (IOPC) by the families regarding an 'offensive' encounter with one of the watchdog's regional directors. Dr Kumar told The Sunday Times newspaper that their meeting with the IOPC, nine months after the attacks, began with a prayer, which he found 'patronising'. The issue was not discussed with Mr Streeting on Monday and would require a different meeting, he told reporters. A DHSC spokesperson said: 'Nottinghamshire Healthcare NHS Foundation Trust and NHS England have accepted all the recommendations made in both the CQC and NHS England-commissioned reviews into the care and treatment received by Valdo Calocane. 'The Health and Social Care Secretary has called for recommendations from both reviews to be implemented as soon as possible and met with the bereaved families today to discuss the NHS England-commissioned Independent Homicide Review. 'As part of this work, NHS England has developed and is actively implementing evidence-based national guidance, so that all trusts are clear on the standards of care expected for patients with serious mental illnesses. 'We remain committed to delivering the fundamental changes needed to mental health services to prevent similar tragedies from occurring in the future.'

Woman suing NHS trust after blade broke off during surgery and lodged itself in her body
Jane Harvey* suffered horrendous physical and mental consequences when, during an abdominal hysterectomy in October 2023, the tip of one of the surgeon's blades broke off and lodged inside her without any of the operating theatre staff noticing or an X-ray spotting it. As a result the 44-year-old had to undergo further surgery to remove the mislaid blade part and stay in hospital longer than planned, needed extra time to recover and suffered nightmares, panic attacks and loss of appetite. She is now suing the NHS trust concerned for damages because of her experience. She was 'shocked, horrified and upset' when she learned that surgeons had left some of their kit inside her. She was also worried after being told that she was at increased risk of infection, which meant she had to take antibiotics. Given what had happened, the thought of having a second operation left her 'drained and scared'. Harvey, an administrator in a law firm, ended up 'paranoid and anxious' that not all the surgical equipment had been safely removed. She felt constantly sick that something was in her body that should not be there and lost her desire to eat. She also lost trust and confidence in those treating her. 'This case is a shocking example of how faulty medical equipment, compounded by failures in surgical and diagnostic care, can result in serious harm to patients,'said Ikhira Thandi, a litigation legal assistant at Lime Solicitors, which is acting for the woman in her lawsuit. 'Our client not only had to endure a second major surgery but has also had the lasting psychological impact of knowing a broken surgical tool was left inside her. Patients should be able to trust that equipment used in their care is safe, helping to deliver their treatment, not hinder it.' Three months after the incident the patient's consultant apologised for it and explained that the dislodged blade tip was due to a manufacturing fault. James Anderson, Lime's head of medical negligence in the West Midlands, said: 'Unfortunately this is not an isolated incident. Across the NHS there is evidence of faulty equipment causing avoidable patient harm. These failures carry a real human cost.' The evidence presented at an inquest last year led to a coroner issuing an unequivocal warning about the danger that inadequate medical equipment can present. Georgina Nolan, the senior coroner for Newcastle and North Tyneside, issued a prevention of future deaths report after hearing the inquest into the death of Michael Walton. The 66-year-old underwent heart bypass surgery in Newcastle on 13 June 2023 and was judged to be at low risk of complications. However, the surgeon's preferred type of cannula was unavailable 'due to supply issues' so they instead used one with a slightly shorter tip. However, as the prevention of future deaths notice explained: 'During the course of the procedure the aortic cannula became dislodged, causing a loss of perfusion and a prolonged period of interrupted blood flow to the deceased's brain, which caused an ischaemic hypoxic brain injury from which he died on 13 July 2023.' In the matters of concern she outlined in her report, Nolan said that 'the cannula type contributed to its dislodgement from the lumen of the aorta and to Mr Walton's death'. And, she added, the events investigated at the inquest showed that 'using suboptimal medical equipment poses an avoidable risk to patients of significant harm, including death'. * name has been changed
