Conservationists abseil into 60-metre gorge to tackle invasive plant species
Conservationists have abseiled down a 60-metre gorge in the Highlands to tackle invasive species such as Japanese knotweed in a bid to protect biodiversity in Scotland.
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.'

Birmingham prehistoric giants exhibition set for summer opening
An exhibition featuring life-sized 3D models and partial skeletons of giant prehistoric animals will open this developed by the Royal Belgian Institute of Natural Sciences, will display animals that roamed the Earth after the extinction of the dinosaurs 66m years them will be the Otodus megalodon, known as the mightiest shark of all time, the woolly mammoth, and the Gigantopithecus blacki – an Asian primate the size of about three exhibition will open at Birmingham Museum and Art Gallery on 2 August before travelling to the National Museum of Scotland in Edinburgh in January. Visitors will be able to learn about the processes behind palaeontology, including the methods around fossil discovery and said there would also be immersive projections to transport audiences the natural habitat of the colossal lifeforms. 'Inspiring installation' They said the exhibition served as a "poignant reminder of nature's fragility" and the urgent need to protect Mensah and Sara Wajid, co-chief executives of Birmingham Museums Trust, said the "inspiring installation" captured the imagination with its "monumental scale" and delivered a vital message about Nick Fraser, keeper of natural sciences at National Museums Scotland, said the exhibition helped to shine a light on creatures which existed in the "relatively neglected" period since the dinosaurs' extinction.

Urgent warning to Bunnings shoppers over popular product sold in stores
Scientists have raised the alarm over a popular plant sold in hardware stores across Australia which could cause billions of dollars in environmental damage. The Gazania flower, an ornamental plant originally introduced to Australia between the 1950s and 1970s, is now considered highly invasive. The species poses a major threat to local ecosystems and the economy with warnings it could cost the agricultural sector up to $5billion a year. The once-decorative flower has since spread across vast areas, including grasslands, sand dunes, stream banks, roadsides, wastelands, and farmland in Western and Southern Australia. It is particularly problematic in grain crop fields in low-rainfall regions of South Australia, where farmers are struggling to control it using standard herbicides. Gazania plants and seeds are widely available for purchase across Australia, including at major retailers like Bunnings, Amazon, and online garden stores. 'There are major concerns that Gazania is killing productive land with crops unable to compete against such a vigorous weed,' researchers from LaTrobe University said. Muhammad Adnan, a PhD student at the La Trobe Institute for Sustainable Agriculture and Food (LISAF), led a study on the weed's resilience. Thousands of seeds were collected from across Australia to test how they responded to different environmental conditions. The research found the seeds could survive and germinate under a wide range of stress factors, including light and temperature extremes, salinity, moisture, and varied burial depths. 'It suggests they could become a problematic weed year-round in many parts of Australia, potentially leading to high infestation levels,' Mr Adnan said. The Invasive Species Council has called for a nationwide ban on the sale of Gazania. 'Gazanias are not only overrunning native grasslands, coastlines and roadsides, they are moving into grain production areas, choking out crops and costing farmers,' Invasive Species Council Advocacy Manager Imogen Ebsworth said. In a statement to Daily Mail Australia, Bunnings said its sale of the flower complies with all relevant regulations. 'Like many nurseries and retailers, we sell a wide range of locally-sourced plants across our stores and we work hard to create an assortment that caters to customer preferences and demand,' a spokesperson said. 'As always, we closely follow all relevant local biosecurity regulations and the advice of regulators about the plants we sell.' The Victorian Government has officially listed Gazania as a highly invasive species, and South Australia banned the plant altogether in March 2021.

Inside the Edinburgh firm on a mission to end fuel poverty
Urban Tide is a data company focused on unlocking information to deliver targeted solutions to businesses looking to improve sustainability outcomes. The founders met while delivering an ambitious 'Future Cities' programme that made them realise combining datasets was the future of targeted decision-making, but that many barriers stood in the way. Now the 15-strong company is a key partner in a five-year research project looking to link health data with household data to improve children's health. Specifically, it's looking at preventing the respiratory problems caused by damp and mould in poorly insulated or poorly ventilated homes. It's led by Dr Olivia Swann who is both a paediatrician and a researcher at the University of Edinburgh. 'The work that Livvy [Dr Swann] is doing is pretty fascinating,' Tricker said. 'The UK has the leakiest homes in Europe. It's a combination of having a lot of old stock, the way we build them is not that efficient and we're not really considering the thermal efficiency of buildings. 'The retrofit programme at scale needs to really be ramped up because if we reduce energy, we reduce our bills and make our homes more comfortable. But – and here comes the but –there's a risk if you clad a home and make it nice and insulated, it's not well ventilated. If you don't consider the ventilation systems, you can increase the risk of mould build-up, which can then lead to the risk of black mould, which, if you've children in the house, can lead to an increase in asthma and a whole host of health implications for later life.' Thanks to Urban Tide's unique access to system data from electricity smart meters, it can provide the research team with information that uses AI and household-level information to predict the risk of fuel poverty. Added to this is the Scotland-wide health data, held securely and strictly anonymised, which Swann's team can overlay with the data provided by Tricker's team, as well as other advanced data sets. This research, inspired by the children coming into Dr Swann's clinic with respiratory infections, is only possible now that all the pieces of the data jigsaw are available. Currently, it would not be possible even over the border in England, and interest from partners has exceeded all Swann's expectations. 'I've been really overwhelmed not just with the amount of interest but also just how incredibly collaborative and how much goodwill there is from industry, from policymakers and from third sector,' Swann said. 'We arranged a project launch event and I thought it would be 20 people and some sandwiches. Instead, we had 130 people and 50 different organisations. Most of those people I had met on Zoom or Teams, and then they had come in person because they felt so strongly about this issue. I think that is a real testament to how important people think this issue is and the will for it to be better.' It's the Goldilocks analogy of 'just right' as it applies to the population of Scotland and the quality of the data, alongside the expertise of companies and researchers and the involvement of Scottish government in potentially turning this research into policy that inspires Tricker. 'We're always looking at how we can use data to help solve a number of these large societal challenges,' he said. "So we wanted to build a platform that could bring in real-time data,' he said. 'We work across the transport sector as well, because they collect lots of real-time information. By combining that with other static data sets, you can start to see patterns. 'In the transport sector, for example, we're working with Cycling Scotland and other partners across local authorities and regional transport partners to try and help put in infrastructure where it's needed.' With this research project involving so many datasets from different partners, including, for the first time, Scottish government data on every intervention made so far to make houses warmer, the ethics of data use have been a priority. 'This data could not be harder to bring together,' Swann said. 'All of the data goes into the National Safe Haven, which is incredibly well protected. The data is then linked there, and it's anonymised before we begin to access it. So we never know who anybody is. 'We have a fantastic patient and public engagement group too and a lot of the discussions we've had with them have been about the acceptability of using these different kinds of data, bringing them together and all of the security measures around them.' Tricker adds that the anonymity of the data Urban Tide is using is absolutely key. It is not interested in personal details but looking for patterns in usage so the right interventions can be made. It will shortly be launching which will open up the data it has collected on transport across Scotland, including cycling networks, so it can be used to make local and national decisions. 'I'm quite excited about launching to really showcase some of our AI technologies and obviously help to promote more open data generally as well,' he said. Urban Tide is already working internationally from its Edinburgh base. It is leading an open data training programme for Ireland's public sector to comply with a European directive to make public data more accessible, and the team is also working on smart city plans in the middle-east and Australia. After 11 years of organic growth, bootstrapping and pivoting as the technology and AI capabilities develop, it is now looking to raise some investment. Assisting with this is Mountside Ventures, which it sees as a 'badge of honour' as it selects a only handful of companies to work with each year. 'The next three years are about really consolidating the business and the technology that we've built across UK and Europe and the next round after that would be to expand into America. We're on the journey of the 'three I's, so there's the identification piece, then there's the intervention and then how do you measure impact? We are also cross-sector. It's one of the challenges of our business, having to work in the energy sector, the transport sector, and then combining data from across the different sources. 'But that's also the opportunity because as more data are being opened up and used, the convergence of all these different types of data really unlocks new opportunities.'
