Conservationists and scientists have warned that the Minerals Council of Australia’s proposal to employ artificial intelligence for faster national environmental approvals could generate “Robodebt‑style” failures, further endangering already vulnerable species.The council has asked the federal government to allocate $13 million for a pilot that would use AI to help companies draft assessment applications and assist regulators in decision‑making.The Biodiversity Council – a consortium of independent experts from eleven universities – told Guardian Australia that while AI may assist with routine tasks, automating whole environmental assessments could lead to opaque, flawed decisions that push threatened species closer to extinction.“Robodebt” refers to the automated welfare‑debt recovery scheme that, between 2015 and 2019, wrongly accused hundreds of thousands of Australians of overpayments, highlighting the danger of opaque algorithmic judgments.Lis Ashby, the Biodiversity Council’s lead on policy and innovation, noted that the cornerstone of Australia’s environmental protection, the Environment Protection and Biodiversity Conservation (EPBC) Act, is riddled with vague language and broad ministerial discretion, which hampers rule‑based decision‑making and would be even more problematic for an AI tool.She added that establishing clear rules in the National Environmental Standards, including explicit definitions of unacceptable outcomes, would accelerate assessment times even without AI and is essential for any future automation.Brendan Sydes, national biodiversity policy adviser at the Australian Conservation Foundation, expressed scepticism, stating that “technology can be a good servant but a poor master.” He urged the government to focus on closing existing data gaps on threatened species and habitats rather than relying on AI.Prof. David Lindenmayer, a forest ecologist at the Australian National University and Biodiversity Council member, highlighted that one‑third of Australia’s threatened species have not been monitored and many others suffer from patchy data, gaps traditionally filled by expert consultation.He warned that AI decisions are only as reliable as the data they are fed, and most threatened species lack publicly available information, even basic location data, risking decisions based on outdated or incomplete evidence.The Albanese government recently passed reforms to the EPBC Act after a 2020 review found the legislation failing to protect species and habitats.Prof. Hugh Possingham, a leading conservation biologist at the University of Queensland, argued that AI models need robust training material, and the past two decades of EPBC approvals are “clearly unsuitable” because the Act has demonstrably failed to safeguard the environment. He suggested that hiring more human assessors would be a more effective way to speed up evaluations.Tania Constable, chief executive of the Minerals Council, dismissed the Robodebt comparison as “disappointing,” insisting the proposal is innovative and could strengthen environmental protection while improving efficiency. She said the AI tools would support human decision‑making for both regulators and project proponents, helping navigate the complexity of EPBC assessments.A federal government spokesperson said budget decisions on the AI trial will be made “in due course,” but the environment department is exploring how AI could simplify application processes. The statement emphasized that “decisions about whether to approve projects must, and will, always be made by assessment officers, not by AI.”Nonetheless, officials acknowledged that AI tools have the potential to save time, reduce uncertainty, and translate technical language for stakeholders.

Mayor Claudia Kalisch, vice‑president of the German Federation of Cities and leader of the Green‑party city of Lüneburg, announced a push for a nationwide ban on night‑time use of robotic lawnmowers. The proposal aims to curb injuries and deaths among hedgehogs and other small nocturnal animals that frequent residential gardens after dark.Recent research has highlighted that the fast‑moving blades of autonomous mowers pose a hidden danger to wildlife active between dusk and dawn. Hedgehogs, which often curl into a ball when threatened, are especially difficult for mower sensors to detect.Kalisch told the Funke newspaper group that urban green spaces have become critical refuges as development and intensive agriculture shrink natural habitats. She noted that petitions urging the ban have amassed tens of thousands of signatures earlier this year, reflecting broad public concern.In addition to legislative pressure, the mayor called on manufacturers to develop hedgehog‑friendly technology. She emphasized that industry responsibility is essential for protecting biodiversity and improving city life quality.The European red‑list classifies hedgehogs as "near threatened" since 2024, after a documented 30% population decline over the past decade. Beyond mower hazards, motorised leaf blowers, vacuums, and vehicle collisions—responsible for up to one in three fatalities—exacerbate the species’ decline across Europe.Scientists at the University of Oxford, in collaboration with Danish colleagues, recently demonstrated that hedgehogs can hear high‑frequency ultrasound, opening the possibility of sonic road repellers to deter them from dangerous areas. The same team has produced 3D‑printed, crash‑test dummy hedgehogs to work with manufacturers on a future certification scheme for "hedgehog‑safe" mowers.Study co‑author Anne Berger of Germany’s Leibniz Institute for Zoo and Wildlife Research warned that injuries from robotic mowers place an "enormous burden" on animal‑care centres, with many victims discovered days or weeks after the incident, enduring prolonged suffering.German law already protects hedgehogs, imposing fines of up to €65,000 for illegal trapping, injury, or killing. Several cities—including Cologne, Leipzig and Munich—have already outlawed night‑time mower operation. However, a recent attempt by the Greens to enact a statewide ban in Bavaria was rejected.

A recent study published in Nature Communications by the UK Centre for Ecology & Hydrology (UKCEH) has sounded the alarm on the precarious state of Britain's native species. The merlin, Britain's smallest bird of prey, is among more than 200 species that could become extinct in the UK if immediate action is not taken to address climate change and unsustainable land use. The study, led by senior ecologist Dr. Rob Cooke, indicates that the next 20 years will be decisive in determining the fate of dozens of native species. By 2050, the British Isles, already one of the most nature-depleted regions in the world, may reach an ecological "point of no return." The researchers modeled six future scenarios with varying levels of greenhouse gas emissions and land management practices. The worst-case scenario, which involves environmentally damaging agricultural and urban intensification and 4C of global heating above pre-industrial levels, could lead to the extinction of 196 plant species, 31 bird species, and seven butterfly species in Britain. This represents losses at more than three times the historical extinction rate. In such a scenario, many areas of the country could lose up to 20% of their existing local species. The merlin, mountain ringlet and large heath butterflies, as well as plants like burnt orchid, grass-of-Parnassus, and Alpine gentian, are among those at risk of being lost. However, the study also offers a glimmer of hope. If society adopts more sustainable climate and land use policies, 69 fewer species could become extinct compared to the worst-case scenario. This underscores the critical importance of immediate action to curb emissions and adopt sustainable practices to protect Britain's biodiversity.

David Attenborough’s voice returns to British screens in ‘Secret Garden’, a BBC One series launched to celebrate the network’s 100th birthday. Unlike his classic wildlife documentaries, the show turns the lens toward the UK’s own backyards, exploring how gardens can rival tropical rainforests in biodiversity.Series producer Bill Markham explains that the programme deliberately avoids the usual “lions and tigers” spectacle, aiming instead for a relatable, garden‑centred narrative. He notes that British gardens collectively cover more area than all national nature reserves combined, and that an average garden can host up to 2,600 different species.The series tackles the contentious issue of domestic cats. With 9.5 million pet cats in Britain, Attenborough reveals they may kill around 55 million birds each year. Simple measures—such as fitting cats with bells—can slash hunting success by one‑third, while raising bird feeders reduces fatalities further.Markham stresses that the current predator‑prey balance is “unfair on the prey”, noting that cats are “the biggest predator in our gardens” yet are constantly fed, leading to an unsustainable population. He cites ecologist Dr Davide Dominoni, who suggests that keeping cats indoors during the breeding months of April and May could dramatically lower bird deaths.Beyond cats, the series examines other garden‑linked wildlife challenges. Each year, over 30 million pheasants—an Asian species—are released into the countryside, where they prey on native insects, reptiles, and amphibians. Markham argues that despite the countryside lobby’s claim that pheasant shooting sustains rural jobs, the practice “mess‑es with the ecology”.‘Secret Garden’ also showcases rare footage, including a pine marten hunting sand martins, an otter preying on ducks, and intricate mayfly battles reminiscent of the famed “snakes vs. iguana” scene from Planet Earth II. These moments underline the hidden drama unfolding in everyday green spaces.Markham hopes the series will soothe the growing eco‑anxiety many feel about climate change. He points out that the UK boasts roughly 25 million gardens, with 80 % of the population having access. Simple actions—like planting a native tree to boost caterpillar supplies for birds—can make a measurable difference.While the show may provoke cat owners and countryside advocates, Markham believes the nation’s love for “animals, gardens and David Attenborough” will drive a collective re‑thinking of garden stewardship. As Attenborough reflects, his first encounter with nature likely occurred in his own garden, setting him on the path to becoming the world’s most renowned naturalist.‘Secret Garden’ airs from 5 April on BBC One and iPlayer.

The reintroduction of beavers in Dorset has shown promising results, with the animals building a 35-metre dam and creating a deep, wildlife-rich pool. By coppicing trees, they have allowed more light in and improved habitats for plants, insects, amphibians, birds, and bats.Trail cameras have captured footage of an otter fishing in the pond, as well as a barn owl hunting there. Volunteers have spotted birds including redpolls and water rails. The cameras also captured footage of two of the beavers mating, indicating they have settled in their new home and that there could be kits this summer.Despite some hitches, including the death of a male beaver and the relocation of a female, the western pair of beavers has been busy doing their engineering work. The National Trust, which is in charge of the project, said it was thrilled with the progress, highlighting the astonishing effect on the ecosystem in a relatively short time.Gen Crisford, the National Trust's wetlands project officer, said setbacks were inevitable but expressed hope for a 'happy ever after moment' with the western pair. The project allows for the release of 10 to 25 adult beavers, with the next release expected to take place this autumn.

In a groundbreaking experiment conducted in Colorado's Rocky Mountain meadows, scientists heated a patch of land by 2C for 29 years. The results are alarming: the area transformed from a lush, diverse grassland into a desert-like scrubland dominated by sagebrush. This 'shrubification' process, driven by rising temperatures, threatens the very existence of alpine grasslands worldwide.The experiment, conducted at the Rocky Mountain Biological Laboratory, involved warming five plots of 30 sq meters each by 2C using electric infrared radiators. The results showed a 150% increase in shrubs in warmed plots compared to those without heating. The surface soil dried by up to 20%, and shallow-rooted plants became stressed, leading to the extinction of some wildflowers.The implications extend far beyond Colorado. Alpine grasslands, which host 50% of European flora on just 3% of land, are particularly vulnerable. As temperatures rise, these ecosystems are likely to be irrevocably changed, leading to a loss of biodiversity. The phenomenon of 'shrubification' is not limited to mountain environments; it's also observed in Arctic landscapes, where shrub cover expanded by 2.2% each decade between 1984 and 2020.Conservation ecologists warn that while shrubs and trees bring benefits like shelter and carbon sequestration, their rapid expansion in cold environments is a symptom of climate change. The speed and scale of these changes are concerning, with potential knock-on impacts on the carbon cycle and ecosystem balance.As Lara Souza, lead researcher, notes, 'It's like flowers on steroids.' However, this vision of abundance is tinged with sadness at the prospect of irreversible changes to fragile landscapes. The future of these ecosystems, and many others like them, hangs in the balance as global temperatures continue to rise.

Cambodia's limestone caves have long been a mystery, hiding secrets beneath their rugged exteriors. Recently, a team of explorers ventured into these karst formations and uncovered new species that have shed light on the country's rich biodiversity. The discovery highlights the importance of preserving these unique ecosystems, which are home to a wide range of flora and fauna. Cambodia's limestone caves are a prime example of the karst ecosystem, a type of landscape formed from soluble rocks like limestone. The new species found in these caves are a testament to the region's incredible natural heritage. As researchers continue to explore and study these ecosystems, they are gaining a deeper understanding of the complex relationships between species and their environments.
