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.
Environment
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.

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.
2025 marks the fifth year that NHBS has participated in Plantlife’s #NoMowMay campaign which encourages people across the UK to put away their lawnmowers and let their grass grow wild throughout the spring, with the aim of providing vital habitats for a wide range of species. As in previous years, we requested that the verges and lawns surrounding the premises be spared from mowing or strimming from late April and all through May to allow more plant species to flower.
We’ve seen good numbers of daisies, buttercups and Germander Speedwell alongside a handful of charming clover species including Red and White Clovers and Black and Spotted Medick. Ribwort Plantain, Common Vetch, Ox-eye Daisy and docks are adding height in places and a handful of common grass species are present and swaying nicely.
Common Spotted Orchid
We do have one beautiful Common Spotted Orchid flowering now as June begins, though sadly, there’s not been returning Bee Orchids this year, for the first time while we’ve been participating in the campaign.
There’s been a fair few bees, wasps, flies and beetles visiting the flowers, though invertebrate activity all round has felt somewhat diminished from previous years. Through May we had scattered sightings of Orange-Tip, Peacock and Tortoiseshell butterflies, and now as June is arriving Meadow Browns have emerged.
#NoMowMay is a fantastic initiative by Plantlife that has highlighted the importance of giving wild plants places to thrive through a crucial stage in their lifecycles and therefore enrich and advance the opportunities for pollinator species, and the wider web of life that depends upon green spaces, including us humans. It’s vital that spaces are left wilder for longer than May, and to encourage this, Plantlife are encouraging the public to let their lawns or grassy areas continue to bloom through June (and again, ideally beyond) with #LetitbloomJune! We’re hopeful that our lawn will be left to flower throughout the summer too.
Outside NHBS at the beginning of June 2025
At NHBS we offer a large variety of books for learning more about habitat maintenance, the importance of species who rely on the restoration and reinvigoration of wilder spaces and many helpful field guides for identifying who’s growing in and visiting your local park or garden!
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.
Haunted by war and loss, Merlin and his wife Lizzie leave the bustle of London and relocate to his childhood farm in Cornwall, only to find new battles awaiting them; crippling debt, a fragmented ancient rainforest, and Merlin’s father struck down by COVID-19. Drawn into the rainforest’s depths, they discover a desperate fight for survival, aiming to save this magical habitat while trying to heal from their own battles.
Merlin Hanbury-Tenison is a Cornish conservationist and veteran who founded The Thousand Year Trust, Britain’s rainforest charity. The charity’s mission is to catalyse the movement to triple Britain’s rainforest cover to one million acres in the next thirty years. His work has been featured in National Geographic, the Guardian and on the BBC. Merlin lives in a rainforest in Cornwall with his wife Lizzie, an entrepreneur and business leader, and their two young daughters.
We recently had the opportunity to speak to Merlin about his first book, including how he came to write it, how important he thinks species reintroductions are in Britain, which challenges he’s faced and more.
Can you tell us a little bit about yourself, and what inspired you to write Our Oaken Bones?
I was born and brought up on Bodmin Moor on a small upland hill farm with a slice of stunning and rare ancient Atlantic temperate rainforest at its heart. I left to join the army when I was 19 and served on three tours of Afghanistan. After returning, I began to suffer from complex PTSD and found the rainforest to be the best place to escape to and heal. At the same time my wife, Lizzie, was also suffering psychologically having gone through two traumatic miscarriages and my father had almost died from very severe Covid. All of us found the rainforest to be the best place possible to heal, restore and recover. I was inspired to write Our Oaken Bones as I want everyone to have access to the kind of healing that we experienced, and for all of us to use that knowledge to heal the rainforests of Britain in return. We used to be a rainforest island with 20% of our landmass covered by this beautiful habitat but almost 99% of it has been cut down and destroyed. I hope that Our Oaken Bones might act as a catalyst to ensure that this is the bottom of the bell curve and that we don’t destroy any more of this vital habitat. With every year that passes I hope that we will see more rainforests being restored and planted across our western uplands.

This book blends elements of biography, natural history, and scientific discussions to combine your personal journey with biodiversity and the pioneering research being undertaken at Cabilla. What motivated you to adopt this multi-faceted approach to writing?
We are all a part of nature, not apart from it – I am passionate about helping people to realise and remember this. It’s easy to say but much harder to feel. I thought that writing a book about trees would appeal to a small audience who are already interested in that subject. Writing a book about the people who live in, and are working to save these rainforests, felt like a subject that would be more engaging and would capture people’s interest. Rainforests are stunning, vital and rare. All I hope for is that people who didn’t even know that we have rainforests in the UK will read this book and finish it in love with the habitat and passionate about saving them. These are our most romantic and folkloric spaces, but many people are unaware of them or their decline. I hope that by weaving personal, historic and scientific narratives together we can shine a light on this important subject.
In Chapter 6, you detail your successful journey reintroducing beavers to Cabilla in 2020. How important do you think reintroducing native species to the UK will be in restoring our natural world, and are you hoping to introduce any other species to Cabilla?
I believe this is a vital area. We live on an island – if important native species are removed and new, non-native species are introduced the results can be catastrophic. This is well understood on islands like Australia and New Zealand, but in the UK, we seem to have a bit of a societal blind spot about it. Returning beavers to the Cabilla Valley has created the most wonderful explosion in biodiversity and habitat abundance. The change was near immediate and very evident. I believe that we can create similar improvements in the British countryside with the slow and careful return of other species, like Pine Martens and wild cats. This should never be rushed, and the most important focus area is ensuring that everyone in a catchment or a release area is on side and positive about the changes. This is all part of the effort to return to a more equilibrious state of British flora and fauna where species that evolved here are interacting in a more natural way together. It’ll be a very long process, multi-generational, but I’m positive that as long as we all remain optimistic we can restore much of what we’ve damaged and lost over the previous centuries.
There is often friction between conservationists and farmers in relation to the effects of livestock on landscapes, but I really enjoyed hearing about your work with farmers to create a blueprint for new farming methods focusing on ecological and economic benefits. How important do you think the shift from working against farmers, to working with them, in conserving our shared landscape will be?
This will all be impossible without the farming community. About 70% of the UK is farmland so we will never be able to combat climate change, restore biodiversity or bring back our rainforests if we don’t work closely and compassionately with farmers. This should never have been an issue historically and I believe it comes from a place of misunderstanding and poor communication. Conservationists and farmers should be the closest of collaborators and colleagues. We are all striving for the same goal; a Britain which provides food for all those who live in it, has an improving and resilient countryside and is full of some of the most stunning natural habitats on earth. Farmers are the key to making this happen and we can help them by ensuring that Government is providing them with the support and guidance to farm in a way that meets all these goals.
The Cabilla Cornwall Retreat offers a unique space for wellness groups, veterans, key workers and individuals to experience the wonders of nature. What are the key benefits of connecting with nature for well-being, and how does this align with the broader goals of the Thousand Year Project?
There is some simply stunning research underway which demonstrates how spending time in native rainforest environments can be beneficial for human psychological and physical health. I am a living example of this, as are many of my family. We have brought a large number of people into the Cabilla Valley as part of the retreat business here and the impacts have always been heart-warming and invigorating. We always do this work with a focus on the habitat first to ensure that we aren’t bringing people into the rainforest at the detriment of the habitat. This is very important. We are currently living through a mental health pandemic and an obesity crisis. There are many reasons for both of these issues and there are also many cures and methods to help alleviate them. The natural world, and rainforests in particular, are a key weapon in this fight. I would never claim that they might replace clinical or pharmacological healing, but we must begin to view all the options side by side and not in isolation. I have seen such marvellous healing impacts in the valley here and I believe that everyone in the UK, especially those who live in urban areas, should be encouraged and assisted in accessing nature as part of their general health and wellbeing.
Have you faced any significant challenges over the past few years that you can share with us?
So many! This would be another book in itself. Running a small business has been an adventure but I won’t pretend that it hasn’t been extremely difficult. The state of our economy and the environment for small business owners is pretty dreadful in the UK right now. When you add that Cabilla is a hospitality business set up during the Covid lockdowns and have then had to survive through all the financial conniptions that our country has been going through, it has resulted in many sleepless nights. Setting up a charity is also a very challenging undertaking and the ability to fundraise at the moment in the UK is particularly difficult. It took me over a year to convince the Charity Commission that we even have rainforests in the UK and that’s before we even entered into the treacle-like bureaucracy of the charity sector. Running a farm is also very challenging at the moment as we have departed the EU, therefore the subsidy systems are changing which has created a number of very difficult financial implications that we’re still trying to work through. This is all before I even come to the difficulty of reintroducing beavers and then keeping them in their government mandated enclosure – but there’s a whole chapter on that in the book, and I don’t want to spoil the fun here!
What do you hope other landowners can learn from the pioneering and vital work you’re doing?
My hope is that the Thousand Year Project that we have started in the Cabilla Valley will act as a blueprint for other interested farmers and landowners on the uplands who are looking to evolve and transition their farming techniques to one that works with nature rather than against it. We are a small farm and below the average farm size across the UK, so this isn’t some unachievable large-scale project that the average farmer wouldn’t be able to do. Everything that we have done here has been designed to not only repair biodiversity and the habitat but also to create a more resilient farming business model under the new subsidy and farm payments system. My hope is that others will take some of what we’ve done here and implement it on their own farms. This is how we will one day come to see rainforests across the uplands and once again view them as a bedrock of our cultural landscape.
Finally, what are your hopes for the future of Cabilla?
I would love to find a way to bring the valley into some form of public ownership so that the work that has begun here will be guaranteed and continue long after I have gone. The whole point of the Thousand Year Project was to create a multi-generational effort. This should be how all land strategy is viewed and conceived. I want my own children to feel free to do whatever they choose to with their lives in the knowledge that the rainforest restoration that we have begun at Cabilla will outlast all of us. I hope that this will become a national project that truly continues until our rainforests have returned across much of our uplands.
This comprehensive guide describes how wildlife can be monitored and recorded in a non-intrusive way using well-developed and reliable technology. Detailing key techniques for capturing high-quality footage of a range of species, from nocturnal mammals to elusive birds, this practical resource is ideal for both professional ecologists and amateur naturalists alike who are seeking to enhance their understanding of the natural world.
We recently spoke to Susan about her latest book, where she explained how she first started working with visual systems, how ecological and wildlife-watching camera systems differentiate, and more.
Firstly, could you share a little bit about yourself and your background working with visual systems?
My background is in physics and engineering, but I have had a keen interest in wildlife from a very early age. Since moving to Devon some years ago, I developed my interest in photography and wrote several books on various technical topics. I used trail cameras before they became ‘famous’ and finding some aspects frustrating, moved to bird box cameras – I then became interested in using security cameras with separate recorders as they had more useful features.
In 2015/2016 I started as a volunteer with Natural England and the Woodland Trust where I was encouraged to develop my ideas for portable CCTV systems, which led to the discovery of three calls of Barbastelle Bats not previously recognised. Further work with dormice, otters, deer, small mammals and birds showed just how well the systems performed, being much richer in features than trail cameras and much less expensive than thermal systems.

Your previous book, CCTV for Wildlife Monitoring was published in 2016. What inspired you to revisit the topic for a second book, and what advancements or changes does your latest title encompass?
My book in 2016 was more of an introduction to CCTV technology, which was just taking off and becoming more readily available. Since then, the technology has advanced dramatically, with HD cameras giving very high-quality images, and recorders becoming available with solid state drives making them very portable.
There are many other features not found in other visual systems – in particular, security recorders have inbuilt video analysis which can be controlled by the user, greatly reducing the amount of video data to analyse. My book has detailed step-by-step instructions for all aspects of the night vision camera systems with the aim of flattening the learning curve.
Night Vision systems are commonly associated with ecological research and wildlife watching, how do the camera systems you describe differentiate from them?
The systems I describe have a raft of features, as described above, making analysis much easier. They can also be left outside unattended and are particularly useful for remote areas. They are also relatively low cost and portable.
Reservoir camera setup.
Why did you feel that it was important to include a section on public engagement and education in this book?
Public engagement is important for raising awareness of the plight of our wildlife, as well as for attracting funding. High-quality videos from security camera systems, particularly of protected or rarely seen species, have proven successful. My book gives step-by-step instructions to encourage the use of this technology without the need for costly specialists.
Regarding schools, introducing children to technology at an early age makes use of the systems less daunting in later life.
Have you come across any emerging or under-utilised applications for this technology that you believe hold potential?
Many of the applications I have developed using my camera systems are new and I believe hold great potential. Because the systems can be set up and left for long periods, it means little or no disturbance to wildlife – for example monitoring breeding birds of prey in remote habitats, observing dormice behaviour in dormouse boxes, or surveying bats in hazardous environments.

Have you encountered any particularly memorable or exciting wildlife captures? Can you share any highlights from your experience?
On the conservation front, discovering new Barbastelle calls was very exciting, as was viewing previously unseen dormouse behaviour. On the naturalist level, filming four young Fallow Deer running round and round my rural garden in play was very heart-warming.
Finally, what’s next for you?
I am planning some research using my systems for small mammals which are often under-recorded. I am also producing educational material for the Mammal Society.
Night Vision and Daylight Camera Systems for Wildlife is available here.
