Conservationists abseil into 60-metre gorge to tackle invasive plant species
Rope access specialists from the National Trust for Scotland (NTS) dealt with invasive plants which had grown in crags in Corrieshalloch Gorge National Nature Reserve in Wester Ross.
The gravity-defying feat is part of efforts to tackle invasive non-native species (INNS), including Japanese knotweed and rhododendron ponticum, under NTS's new Plan for Nature, which identified it as the main driver of nature loss in Scotland.
Property and conservation staff surveyed the gorge, identifying sites where invasive plants had established themselves on the cliff sides before applying a targeted dose of herbicide.
The project aims to protect native flora from being crowded out of their natural habitats.
NTS plans to remove the six most troublesome non-native invasive plants from its estate: rhododendron ponticum, Japanese knotweed, giant hogweed, salmonberry, skunk cabbages and New Zealand broadleaf, and to gradually remove non-native invasive shrubs where they are protecting gardens from coastal spray.
It will also review emerging invasive species, targeting those which are most invasive and have the highest ecological impact.
Rob Dewar, the trust's INNS project officer, said: 'Our work at Corrieshalloch is part of our ongoing nature conservation to remove invasive non-native species and demonstrates the extreme lengths we go to, to protect the places in our care.
'These gravity-defying feats are undertaken by our rope access specialists who support our conservation efforts in these hard-to-reach places where these species can quickly establish themselves, like on the vertiginous sides of the gorge.
'The INNS work is focused on eradicating invasive non-native plants, including Japanese knotweed, American skunk cabbage and rhododendron ponticum.
'The work helps to tackle these species and protect native flora from being crowded out of their natural habitat to safeguard the biodiversity of Scotland's wild landscapes.
'It is thanks to the continued generosity of our members and supporters, including players of People's Postcode Lottery, that we're able to continue our vital work to care for and protect Scotland's natural heritage at this special place for everyone to enjoy, now and into the future.'
Players of People's Postcode Lottery have supported NTS's Love Our Nature project since 2022, which benefited from £900,000 last year, and have raised more than £3.4 million since 2014 to support the charity.
Further funding will support nature conservation work across a variety of habitats including coastal and marine areas, peatlands, wetlands, woodland, and the eight national nature reserves cared for by the trust.
Laura Chow, head of charities at People's Postcode Lottery, said: 'Players of People's Postcode Lottery will be delighted to know they are supporting the important work of NTS to protect the biodiversity of our beautiful landscapes.
'Tackling invasive non-native species is vital to ensure the survival of our native plant-life by protecting the natural habitats in which they thrive.'

WA Museum partnership with Woodside criticised as record-breaking marine heatwave decimates coral reefs
The WA Greens and the state's peak conservation body have condemned the extension of a research partnership between the Western Australian Museum and Woodside, as the state reels from a record-breaking marine heatwave that has killed corals over a 1,500km stretch of ocean. The five-year continuation of the 'longstanding collaboration', in which the gas giant supports the museum's biodiversity research along the WA coastline, would allow for further targeted research along the Gascoyne coast, according to announcements. In a post on its LinkedIn page, the museum wrote that 'to mark the milestone' Woodside was supporting free general admission to the WA Maritime Museum on Sunday 17 August for the 'Woodside Energy Open Day' and the event would feature 'family-friendly activities all about marine science' as part of National Science Week. The new deal – which extends the 28-year partnership – and the open day have been promoted in front page advertisements in WA media this week. Sign up: AU Breaking News email It has prompted fury from climate advocates and the WA Greens as it coincides with the release of research about the extent of the damage caused by a record-breaking, climate-change fuelled marine heatwave to the state's coral reefs. The heatwave, which started to build off the north-west WA coast in August 2024, has been called 'the most severe coral bleaching on record for Western Australian coral reefs'. It has left 75% of affected coral either bleached or dead, according to a group of scientists from state and federal government departments, agencies and universities who worked on this week's report. The WA Greens fossil fuels and climate action spokesperson Sophie McNeill wrote to the museum on Tuesday seeking a briefing from its director Alec Coles 'because it seems like they [the museum] don't understand the relationship between fossil fuel companies and the devastating impacts of climate change we are seeing right now on our marine environment'. 'It is so inappropriate that the WA Museum has chosen to continue its partnership with one of the world's largest fossil fuel companies as our world heritage listed coral reefs are literally dying in front of our eyes,' McNeill said. 'As one of the state's biggest polluters, Woodside should not be allowed anywhere near marine science in Western Australia given they are responsible for the current devastation we are seeing along our coastline that is so universally loved by all.' McNeill expressed concern that children visiting museums to learn about oceans were being exposed to branding from 'the very same fossil fuel giant that is contributing to the death of our coral reefs'. 'It is deeply alarming that our precious institutions here in WA are so deeply captured, just like the WA Labor government, by fossil fuel companies like Woodside,' she said. In a statement, a spokesperson from WA Museum described it as 'independent, science-led, and committed to the people and the environment of Western Australia'. The spokesperson added that WA Museum relies on 'a diverse range of funding sources – including government, competitive research grants, philanthropic contributions, and corporate support'. They continued that 'engaging constructively and transparently with industry' allowed WA Museum to expand knowledge of WA's ecosystems, 'foster dialogue between sectors' and 'ensure that decisions about environmental impact are informed by the best available science'. The Conservation Council of WA said the museum, as a state government institution, should reject the extended sponsorship arrangement. Sign up to Breaking News Australia Get the most important news as it breaks after newsletter promotion 'If there is funding required the government should show some leadership and actually put up the money and ensure that important research is still continuing,' executive director Matt Roberts said. 'So that we're not relying on the very industry that is causing our marine systems to be on the brink of collapse to fund the research into that collapse.' Roberts said the council was organising a 'requiem for our reefs' at the Maritime Museum on Sunday to highlight the 'devastating impact of Woodside's emissions on WA's coral reef system, and calling for public support to stop Australia's biggest polluter from drilling for new gas under the pristine Scott Reef in the Browse Basin'. Paul Gamblin, the chief executive of the Australian Marine Conservation Society, questioned Woodside's motives, asking'what do they seek to gain from it?' 'Particularly given the very clear evidence of the marine environment coming under increasing stress, one might imagine we're going to see more of this kind of sponsorship and public relations.' The spokesperson for the WA Museum said 'Woodside neither directs the research, nor participates in it [and] the Museum retains all intellectual property generated, other than that vested in Traditional Owners'. Woodside referred back to the company statement released last week, which said the ongoing collaboration had 'led to the discovery and description of numerous new species, and significantly increased understanding of the marine environment of Western Australia'. Chief executive Meg O'Neill said last week 'this renewed collaboration reaffirms Woodside's commitment to responsible environmental management and the ongoing discovery of WA's unique marine biodiversity'.

Cat dementia discovery could help Alzheimer's research
Cats develop dementia in a similar way to humans with Alzheimer's disease, leading to hopes of a breakthrough in research, according to at the University of Edinburgh carried out a post-mortem brain examination on 25 cats which had symptoms of dementia in life, including confusion, sleep disruption and an increase in vocalisation. They found a build-up of amyloid-beta, a toxic protein and one of the defining features of Alzheimer's disease. The discovery has been hailed as a "perfect natural model for Alzheimer's" by scientists who believe it will help them explore new treatments for humans. Dr Robert McGeachan, study lead from the University of Edinburgh's Royal (Dick) School of Veterinary Studies, said: "Dementia is a devastating disease - whether it affects humans, cats, or dogs. "Our findings highlight the striking similarities between feline dementia and Alzheimer's disease in people."This opens the door to exploring whether promising new treatments for human Alzheimer's disease could also help our ageing images of older cats which had previously shown symptoms of feline dementia revealed a build-up of amyloid-beta within the synapses - the junctions of brain cells. Synapses allow the flow of messages between brain cells, and losing these causes reduced memory and thinking abilities in humans with Alzheimer' team believe the discovery in cats could help them get a clearer understanding of the process, offering a valuable model for studying dementia in researchers have studied genetically-modified rodents, although the species does not naturally suffer from dementia."Because cats naturally develop these brain changes, they may also offer a more accurate model of the disease than traditional laboratory animals, ultimately benefiting both species and their caregivers," Dr McGeachan said. Will this research benefit cats? The researchers found evidence that brain support cells - called astrocytes and microglia - engulfed the affected synapses. It's known as synaptic pruning, an important process during brain development but which contributes to Danielle Gunn-Moore, an expert in feline medicine at the vet school, said the discovery could also help to understand and manage feline dementia."Feline dementia is so distressing for the cat and for its person," she said. "It is by undertaking studies like this that we will understand how best to treat them. This will be wonderful for the cats, their owners, people with Alzheimer's and their loved ones."The study, funded by Wellcome and the UK Dementia Research Institute, is published in the European Journal of Neuroscience, and included scientists from the Universities of Edinburgh and California, UK Dementia Research Institute and Scottish Brain Sciences.

Cats develop dementia just like humans, study finds – here are the key signs to look out for
It's a debilitating syndrome that cruelly affects different aspects of cognitive functioning – such as thinking, remembering, and reasoning. But dementia, which affects about 57 million people worldwide, is not just specific to humans. Alzheimer's disease, the most common form of dementia, affects cats in the same way it affects humans, a new study reveals. Scientists at the University of Edinburgh say cats showing dementia symptoms – such as confusion, sleep disruption and more meowing – have brain changes similar to those in people with Alzheimer's. Studying feline dementia has the potential to help develop human treatments because the condition between the two species is so similar. And in turn, these treatments could be administered to cats with dementia as well. 'Dementia is a devastating disease – whether it affects humans, cats, or dogs,' said Dr Robert McGeachan, study lead at the University of Edinburgh. 'Our findings highlight the striking similarities between feline dementia and Alzheimer's disease in people.' Around 50 million people around the world live with Alzheimer's disease – which accounts for between 50 per cent and 70 per cent of dementia cases. Although the exact cause of Alzheimer's disease is not yet fully understood, it is thought to be caused by the abnormal build–up of proteins in and around brain cells. In cats, symptoms of dementia include increased meowing, confusion, spatial disorientation, poor grooming habits and disrupted sleep , such as sleeping more than usual or being awake at night. Other key signs include forgetting that they have just been fed, going to the bathroom outside the litterbox and staring off into space while looking at a wall or corner. For their study, the University of Edinburgh scientists carried out a post–mortem brain examination on the brains of 25 cats of different ages after they had passed away, including those with signs of dementia. In the brains of felines with dementia, there was a build–up was found of amyloid–beta, a toxic protein and one of the defining features of Alzheimer's disease, they found. The dangerous protein clumps together in and around brain cells, first forming small clusters, before eventually accumulating into bulky 'plaques'. These plaques build up between nerve cells in the brain and disrupt communication between cells, affecting memory, thinking and daily functioning. Powerful microscopy images also revealed a build–up of amyloid–beta within the synapses – the connections between brain cells – of cats with dementia, as well as older cats. 'We already knew that a toxic protein called amyloid–beta, also seen in human Alzheimer's, builds up in the brains of older cats with dementia,' Dr McGeachan told the Daily Mail. 'What we didn't know was whether it was actually causing damage. 'Our study shows it is – by triggering the brain's immune cells to eat away or engulf the connections between brain cells, called synapses. 'Losing these connections is closely linked to memory and behaviour changes... and it mirrors almost exactly what happens in people with Alzheimer's.' According to Dr McGeachan and colleagues, cats may also benefit from human–designed Alzheimer's treatments (including recently approved anti–amyloid drugs). 'We can use cats to study the disease and develop treatments that could help both animals and people with dementia,' he added. The new study, published in the European Journal of Neuroscience, shows that cats are a valuable model for studying dementia in people. Because of the similarities in the brains of cats and people, scientists could potentially dissect cat brains in the lab to understand more about Alzheimer's in humans. Previously, researchers have studied genetically modified rodents, but these do not naturally suffer from dementia, so cats may be 'a more accurate model of the disease than traditional laboratory animals', ultimately benefiting both species and their caregivers. 'Feline dementia is so distressing for the cat and for its person,' said Professor Danielle Gunn–Moore, study co–author and expert in feline veterinary medicine at the University of Edinburgh. 'It is by undertaking studies like this that we will understand how best to treat them. 'This will be wonderful for the cats, their owners, people with Alzheimer's and their loved ones.' HOW TO DETECT ALZHEIMER'S Alzheimer's disease is a progressive brain disorder that slowly destroys memory, thinking skills and the ability to perform simple tasks. It is the cause of 60 percent to 70 percent of cases of dementia. The majority of people with Alzheimer's are age 65 and older. More than five million Americans have Alzheimer's. It is unknown what causes Alzheimer's. Those who have the APOE gene are more likely to develop late-onset Alzheimer's. Signs and symptoms: Difficulty remembering newly learned information Disorientation Mood and behavioral changes Suspicion about family, friends and professional caregivers More serious memory loss Difficulty with speaking, swallowing and walking Stages of Alzheimer's: Mild Alzheimer's (early-stage) - A person may be able to function independently but is having memory lapses Moderate Alzheimer's (middle-stage) - Typically the longest stage, the person may confuse words, get frustrated or angry, or have sudden behavioral changes Severe Alzheimer's disease (late-stage) - In the final stage, individuals lose the ability to respond to their environment, carry on a conversation and, eventually, control movement There is no known cure for Alzheimer's, but experts suggest physical exercise, social interaction and adding brain boosting omega-3 fats to your diet to prevent or slowdown the onset of symptoms.
