Proposal to reintroduce Eurasian Lynx to Northumberland
A draft proposal for a trial reintroduction of Eurasian Lynx to Kielder Forest, Northumberland has been released by the Lynx UK Trust. The organisation ‘s previous application to reintroduce lynx to the same site in 2018 was rejected by then incumbent environment secretary Michael Gove. He cited the proposal’s failure to properly address the ‘social feasibility’ of reintroduction as reason for rejection. A trial release of lynx may be ecologically feasible but concerns relating to the potential of sheep predation persist. Tony Juniper of Natural England has stated that are introduction of lynx “should be looked at” but “we need more engagement to understand how communities that would be living with these animals would be able to continue with what they do”. Paul O’ Donohue, CEO of the Lynx UK Trust, believes that further attempts to engage farmers and stakeholders would be a waste of time, stating “sheep farmers will never change their position on lynx reintroduction, making more calls for more engagement utterly futile”. Meanwhile, Lynx for Scotland, a separate charitable organisation has coordinated a 100page report which seeks to address the concerns of farmers and other stakeholders, they hope to release a substantiated proposal in the future if social and ecological feasibility for lynx reintroduction can be established.

Peatland Protection
Danes Moss, a lowland raised bog on the outskirts of Macclesfield, is among the scarcest and most threatened habitats in the UK. The carbon storage capacity of the deep peat is invaluable and the open bogland hosts a biodiverse flora and fauna. With disregard to the habitat’s ecological significance, the peatland continues to be targeted as a site for housing development.

A recent planning application from Cheshire East Council has been withdrawn following a campaign from the Danes Moss Trust. CEC have cited ‘incompatibility with its climate and peatland policy’ as reason for the turnaround. The withdrawal has been positively received but campaigners and stakeholders remain braced for a revised proposal. If passed without amendment, ‘part 3’ of the proposed Planning and Infrastructure Bill could make it easier for developers to build on Sites of Special Scientific interest (SSSI) such as this.

Wet Farming

The Fens, Cambridgeshire was once Britain’s largest wetland and has been almost completely drained to facilitate traditional ‘dry’ agriculture and the growth of cereal crops. The Great Fen, between Peterborough and Huntington, represents part of a peatland restoration project within the Fen county and along with four other sites across Europe, has been selected for a wet farming or ‘paludiculture’ trial.
Under the project banner of ‘PaluWise’, the wet farming operation will run for four years under close monitoring. It aims to establish whether rewetted peatlands can be agriculturally productive whilst retaining the biodiversity and carbon storage capacity unique to wetlands.

UN Ocean Summit 2025
Representatives from nearly 200 countries met in Nice, France to discuss marine protection. The summit has culminated in fifty countries ratifying the High Seas Treaty, an international agreement to conserve and sustainably use high seas which lie outside of national jurisdiction. The fast tracking of the treaty has been welcomed as a positive development but significantly China and the US have not agreed to ratify.
Commitments made at the summit represent a small step in the right direction but silence from global superpowers and a litany of feeble sentiments like Emannuel Macron’s announcement that France will “limit” bottom trawling and seek to protect just 4% of its metropolitan waters- shows that we are a far cry from meeting marine protection targets.
A study from Dynamic Planet has suggested that 85 Marine Protected Areas (MPAs) would need to be notified every day if there is any chance of meeting the 30 x 30 target (an agreement to protect 30% of land and sea by 2030). This figure increases with every passing day of inaction.

Poole Harbour’s osprey pair have hatched their fourth chick of the year. The only breeding pair of ospreys on the South Coast have laid a clutch of four eggs for the second year running, and the Birds of Poole Harbour charity has announced that the final chick successfully hatched in the past week. In 2022, female CJ7 and male 002 became the first nesting pair on the south coast in 180 years as part of a reintroduction scheme.

Golden Eagles are spreading their range from southern Scotland into England. Around 50 Golden Eagles have been translocated across Scotland since 2018 in an attempt to save this species amidst major population decline. In the past 7 years, South of Scotland Golden Eagle Project (SSGEP) have successfully translocated 28 juveniles and 15 sub-adult golden eagles from the Scottish Highlands to the Scottish borders. Satellite tagging has revealed that a number of birds are beginning to venture into Northumberland, the North Pennines, the Lake District and even as far south as Lancashire and Yorkshire, offering hope for the future reintroduction of Golden Eagles into England.

Reservoir projects fast-tracked in an attempt to secure England’s water supplies. Two major new reservoirs in East Anglia and south Lincolnshire have been fast-tracked through the planning process as they are now declared as ‘nationally significant.’ As such, the final decisions for these projects will be taken by Environment Secretary Steve Reed, rather than at a local level, with the aim of securing water supplies for future generations. These stores would provide resilience to future droughts in particularly dry areas of the country where water demand is high, and may be completed by 2036 and 2040 respectively. The water industry has welcomed this announcement, but some communities are concerned about increased bills, as well as the potential clearing of homes and farmland to make way for the necessary infrastructure.

Areas of common ground in the Yorkshire Dales are being restored to their ancient glory. A groundbreaking tree-planting programme is uniting farmers and rewilders alike to bring species back to ‘ghost woodlands’. Howgill Fells had been heavily grazed for hundreds of years, but in just over a decade, an extensive rewilding project has planted 300,000 native trees across common land in 64 acres of sheep-free enclosures. Ecologist Mike Douglas recently conducted his first of four annual surveys monitoring birds in the enclosures. His results have revealed the presence of 11 new breeding bird species since his original survey in the early stages of the project in 2016, and numbers continue to increase year on year. 

Policy 

Labour have rejected a proposal to provide every new home with at least one swift brick to help endangered cavity-nesting birds. The proposed amendment to the governments Planning and Infrastructure bill requested that every developer provides a single £35 hollow brick for swifts, house martins, sparrows and starlings in every new build home. This was previously supported when it was tabled on Conversative government legislation in 2023, however the current Labour-dominated committee have now stated they are not convinced it is the right approach. A petition calling for these bricks to become mandatory has now reached 80,000, demonstrating the public’s concern on the matter.

Nature-friendly farming fund to be cut in UK spending review. Labour initially promised £5 billion over two years for the post-Brexit farming fund, which will be honoured until 2026, however in the years following it will be slashed in line with wide-scale budget cuts. This nature-friendly initiative replaced the EU’s Common Agricultural Policy and rewards farmers for stewarding nature, soil, and other public goods, rather than solely for land ownership and cultivation. While DEFRA have stated they are planning a new scheme aimed at smaller farms, many larger-scale ones will miss out on these incentives.

A mosquito-borne disease has spread to the UK and is now affecting wild bird populations. The deadly Usutu virus was first detected in southern Africa over half a century ago and spread to the UK in 2020. Blackbirds are specifically susceptible to the virus, with mass die-offs occurring as a result of the disease across Europe, and it has recently spread across the UK as far as Dorset and Cambridgeshire. Scientists are now monitoring the spread of the Usutu virus amid concerns that climate change may turn Europe into a breeding ground for its host species, mosquitoes, therefore exacerbating the reach of the disease.

Scientists warn about numerous new threats affecting bee populations. A study from the University of Reading has highlighted that war zones, microplastic and air pollution are posing some of the greatest threats to our pollinators. An increase in worldwide conflict has forced countries to grow a smaller variety of agricultural crops, leaving pollinators without a diverse range of food sources throughout the year, whilst investigations into air pollution has revealed that is affecting the survival, reproduction and growth of our key pollinator species. Researchers also tested 315 honey bee colonies and found traces of microplastic contamination within most hives. Professor Simon Potts, the lead author of this report, stated that identifying these news threats and finding ways to protect pollinators early is the key to preventing further population decline.  

Extinction risk 

‘Vulnerable’ cockatoo species facing further habitat loss due to bushfires. Conservationists have warned that the planned burning of 13,000 hectares of forest in East Gippsland, Australia, may jeopardise declining Glossy Black Cockatoos populations. 64% of this species habitat was burned in the 2019-2020 black summer bushfires, resulting in the population becoming wholly dependent on the 48,000 hectares of unburnt coastal forest around Lake Tyers. Glossy Black Cockatoos feed almost exclusively on the cones of black sheoak trees, which are often subject to planned burning programmes. Australia’s biodiversity, wildlife, and habitat are currently under threat from bushfires, prompting ecologists and nature campaigners to highlight the urgent need for careful management, especially with Victoria’s cockatoo population now estimated at a mere 250.

Welsh Celtic rainforests under threat. A 2024 survey investigating the ecology of Welsh rainforests has revealed that only 22% of the temperate rainforests found in this area are in ‘good’ condition, with many others under threat due non-native species, storms and inappropriate grazing of livestock. These rare habitats are only found in isolated areas across the world, including the Woodland Trust’s Coed Felenrhyd near Gwynedd, however it is vital that the remaining  33,024 hectares of rainforest left in Wales are protected. Natural Resources Wales manage seven Celtic rainforest reserves in the Meirionnydd area, and have now stated that these ‘exceptionally important sites’ need conservation and landscape scale management to ensure their preservation.

Climate change 

The worlds coastlines are still in danger even if climate targets are met. Even if the world achieves the ambitious goal of limiting global warming to 1.5°C, researchers project that sea levels are still likely to rise by several meters. New investigations into how ice sheets respond to future climate changes suggest that even with stabilized global warming, this rise may not slow down. A major concern is that melting could accelerate past a viable ‘tipping point’ due to intensified warming from human activity, though scientists are yet to pinpoint this critical threshold. The consequences for coastal communities would be catastrophic, as approximately 230 million people currently live within one meter of high tide lines.

Captive-bred axolotls have successfully adapted to the wild, offering hope for the future of this critically endangered species who have been on the verge of extinction for nearly two decades. In an attempt to trial their reintroduction, scientists have recently conducted a study involving the release and monitoring of 18 captive-bred axolotls into Lake Xochimilco and its neighbouring artificial wetland. Volunteers tracked their movements for roughly 40 days, and the results of this study have revealed that not only have all 18 individuals survived, but those that were recaptured for monitoring have gained weight, suggesting they have successfully adopted natural hunting behaviours. Whilst this study has revealed that species reintroduction is a viable option, ecologist Luis Zambrano has stated the team’s first priority is to improve habitat conditions for axolotl’s already living in the wild.

The only breeding pair of Ospey in southern England have laid four eggs for a second year running. The Osprey reintroduction programme began in Poole Harbour in 2017, and in 2022 female CJ7 and male 022 became the first nesting pair recorded on the south coast of England in 180 years. With the eggs expected to hatch at the end of the month, the Birds of Poole Harbour group have stated that a repeat of all four eggs successfully hatching would be a very promising outcome for their recolonisation, however every hatchling should be celebrated.  

Science and Environment 

A government grant from the Nature Restoration Fund is set to facilitate the eradication of American mink from the Outer Hebrides. Over 2,000 individuals have been captured since the Hebridean Mink Project began in 2001, and in 2018 it was thought that their population had been reduced to a level that was no longer functional. However, data has revealed that 20-30 mink are still trapped annually. The Scottish Government’s grant will enable the installation of more traps, ensuring the eradication of this invasive species from the islands and supporting the recovery of ground-nesting birds and other native wildlife.

Sandeel fishing ban remains in place in the North Sea. Sandeels are a vital source of food for a wide variety of the UK’s marine life and coastal sea birds, and in early 2024 English and Scottish authorities implemented trawling bans due to concerns about declining populations. The EU have now challenged this ban, arguing that the motion was ‘discriminatory,’ ‘disproportionate’ and could threaten commercial sandeel fishing in Denmark. Several key organisations including the RSPB and DEFRA have since advocated for the measure to remain in place, and judges have ruled that there is no legal obligation to reverse this order.

Housing developers in England may be able to build on protected green spaces without needing to replace nature lost locally. The proposed Planning and Infrastructure bill could allow developers to pay into a fund for off-site habitat creation, potentially outside the local area, or even in a different county. While the Labour government aims to streamline development to meet housing targets, concerns are growing that this could harm poorer rural communities and lead to a “cash to trash nature” system, undermining local access to nature and potentially ignoring crucial environmental protection. 

Pollution 

UK is falling behind on its commitment to reduce microplastic pollution. Scientists have revealed that these pollutants continue to infiltrate our food sources, ecosystems and bodies. Researchers are now warning that the UK is falling behind both Europe and the US in the introduction of enforceable targets on microplastic in wastewater and drinking water. As a result of this, they are now encouraging ministers to develop a comprehensive approach to reduce plastic pollution, whilst also providing funding for vital research into safe microplastic exposure thresholds.
