Bringing the Beaver Back to Ealing: A Community-Led Rewilding Success Story

Autumn 2023 saw the exciting return of beavers to England’s capital city, with the release of five animals in an 8ha enclosure at Paradise Fields, Ealing. Here, Dr Abhilesh Dhawanjewar, Technology Lead for the Ealing Beaver Project, shares an account of this community rewilding project, from its conception and achievements so far to hopes for the future of the Ealing beavers.

Bringing the Beaver Back to Ealing: A Community-Led Rewilding Success Story

Eurasian Beavers (Castor fiber), Europe’s largest rodent are incredible creatures with an amazing ability to transform their surroundings, lending them the well-deserved title of ‘ecosystem engineers’. Occupying vast regions across Europe and northern Asia for over 12 million years, they have shaped our waterways and wetland habitats, creating rich and resilient ecosystems supporting a wide diversity of plants and animals. Commercial demand for their fur, meat and castoreum led to relentless hunting and persecution of the beavers, driving them to extinction in the UK 400 years ago. The species narrowly avoided the same fate across Europe, its survival hinging on just eight relict populations that totalled a mere 1200 individuals. Their absence from the UK has coincided with a 90% reduction in Britain’s native wetlands in the last century and increased flood and drought risks. Having realised their ecological benefits, beaver reintroductions across Europe have helped to restore habitats and boost biodiversity. Reintroduction projects in the UK gaining momentum lately.

The Road to Ealing

As the UK government refined its reintroduction strategy, free-living beavers were already on London’s doorstep, with populations expanding in Kent and Oxfordshire. Anticipating their natural return, the London Beaver Working Group was formed in 2021 to proactively manage their arrival. After consultations and site visits, Paradise Fields in Ealing was chosen as an ideal location for a trial reintroduction. The site was already targeted for expensive flood mitigation engineering works, and beavers presented a natural, cost-effective alternative. After a license was granted in January 2023, the project gained momentum, fuelled by enthusiastic local volunteer groups and vital seed funding from Ealing Council and the Mayor of London. Thanks to the collaborative efforts of Ealing Wildlife Group, Citizen Zoo, Friends of Horsenden and Ealing Council with additional support from Beaver Trust, the Ealing Beaver Project was born with three key objectives:

Bring back the Beaver: Reintroduce beavers for their intrinsic value in nature
Mitigate urban flooding: Learn to manage beavers in the urban context and harness their water-engineering skills
Boost Biodiversity: Restore wetland habitat and encourage a richer diversity of flora and fauna
Public Engagement: Foster greater public understanding and coexistence with beavers in an urban setting

What sets the Ealing Beaver Project apart from other similar initiatives is its community-driven and inclusive approach to urban rewilding. While most beaver reintroduction projects in the UK are tucked away in the remote countryside or on vast private estates with paid access and closing times, the Ealing Beaver Project is one of the first fully accessible enclosed beaver reintroduction sites in the UK, offering a rare opportunity for the public to observe and engage with beavers in a city environment. At the same time, it allows local communities to directly benefit from the ecological improvements that beavers bring, such as improved biodiversity, better water management, and revitalised natural spaces.

Progress so far

A family of five Eurasian beavers was introduced to Paradise Fields in Greenford, Ealing on 11th October 2023 and since then, the Ealing Beaver Project has become a flagship example of urban rewilding in London. Within days of their arrival, the beavers had already started shaping their new home, building dams, creating new waterways and pools and kickstarting the transformation of the site into a thriving wetland. To date, they have constructed seven dams across the site, holding more water on the landscape and minimising the flooding downstream during high rainfall events. Their activities have also opened up the overshaded tree canopy, creating a mosaic of habitats supporting greater biodiversity.

Early results from monitoring and ecological surveys are promising: water quality sampling has shown a reduction in nutrient levels such as phosphates and nitrates, as well as total dissolved solids including pollutants and road runoff particulates, in water leaving the site compared to that entering it. Since the beavers’ arrival, the return of several species has also been recorded at Paradise Fields. Invertebrate populations have increased, especially water quality sensitive species such as freshwater shrimp, diving beetles and caddisfly larvae, which in turn has attracted two new species of bats and four new species of birds, early signs of a flourishing, interconnected system. The biodiversity benefits also extend to amphibians with an explosion in Common Frog spawning on site, thanks to the beavers’ ecosystem engineering activities.

Perhaps the most promising sign that the beavers have truly settled into their home came in the summer of 2024, when at least two new kits were born. This historical moment marked the first record of breeding beavers in urban London in centuries. While beavers went extinct in the UK 400 years ago, they likely vanished from London’s waterways even earlier. The fact that beavers were commonplace in London is preserved in the legacy they left in names like the Beverly Brook, a small river in Southwest London whose name is thought to derive from “beaver stream”. It’s the ultimate validation that the urban habitat at Paradise Fields is a suitable habitat, and that beavers and people can successfully coexist in a bustling urban landscape.

On the community engagement front, interpretative signage has been installed on the site to help visitors learn more about beaver adaptations and ecology and visitors are encouraged to log their wildlife sightings on platforms like iNaturalist, further promoting citizen science data collection. The hugely popular Guided Walks and Beaver Safaris led by members of the Ealing Beaver Project team have welcomed hundreds of visitors, offering a first-hand look at this rewilding success story. In a borough-wide naming competition, primary school pupils chose names for four of the resident beavers: “Willow” and “Woody” for the original pair introduced in 2023, and “Chompy” and “Chewbacca (Chewy)” for the kits born in 2024.

The Ealing Beaver Project leadership team also shared their urban rewilding model at the international BeaverCon conference in Colorado, and participated in knowledge exchange panel discussions and workshops. The story of the project has also been beautifully documented in the award-winning short film “Beavers in Paradise” by filmmaker Matt Brierley and commissioned by Consano Earth, which premiered to an international audience for the first time at BeaverCon. Drawing from insights gained from the conference, a pond levelling device was recently installed on-site to demonstrate how water levels can be proactively managed. The project has recently attracted significant support, including a recent grant from the HS2 Community and Environment Fund, which will be vital for enhancing public education and engagement for years to come.

What’s Next for the Ealing Beavers?

The project’s remarkable success has provided a powerful validation of the urban rewilding approach. As it moves towards the halfway point of its five-year license, the key priorities are

The continued monitoring of this evolving landscape.

Documenting the water quality and biodiversity improvements in the area.

Helping to design mitigation strategies that balance beaver activity with the needs of local communities and neighbouring infrastructure.

Public engagement lies at the heart of the project and this will only deepen in the years to come. The revitalisation of this urban green space, right next to a busy retail park, has fundamentally improved how visitors interact with nature. The fully publicly accessible site serves as a vital outdoor classroom, where visitors can witness the dynamism of a beaver engineered landscape first-hand. Fuelled by the recent support, plans are underway to expand educational programs for local schools and the public, demonstrating how people and wildlife can live alongside and benefit from each other in our cities.

The project team is exploring options to trap the eldest daughter, born in 2022 and introduced to Paradise Fields in 2023 for translocation to other suitable beaver projects, helping support the national effort to restore this keystone species. With the recent announcement from the UK government regarding licensing the wild release of beavers, the team is also exploring how this pilot could inform the reintroduction of free-living beavers in Greater London. While Paradise Fields remains an enclosed trial, the project has contributed valuable insights into coexistence, site suitability, and the infrastructural tweaks needed to support beavers in England in the long-term. The hope is that future generations of kits from the Paradise Fields family will be able to roam freely, improving the health of England’s river systems and wetlands.

Perhaps the most anticipated next step is one that the beavers’ meticulous activities have been preparing the site for all along: the reintroduction of water voles. Water voles are Britain’s fastest declining mammal, having lost 90% of their population since the 1970s, due to habitat degradation and fragmentation along with overshading of riparian habitat. Restoring habitats and improving our aquatic ecosystems are a necessary step towards supporting water vole populations and with the beavers’ help, we can improve the health of our wetlands making them more resilient and providing valuable habitat for other vulnerable species.

The Ealing Beaver Project is a testament to the conviction and power of community-led conservation, the profound effectiveness of nature-based solutions to urban problems and the inspiring possibility of welcoming wildlife back into our cities for the benefit of both people and nature.

Interview with RSPB: A Night of Nature

In a first for Europe’s largest conservation charity, the RSPB (Royal Society for the Protection of Birds) is bringing the spectacle of the natural world to the big screen. Coming to London’s Troxy on 6th September, ‘A Night of Nature’ will blend cinema with the immediacy of a concert, thanks to live music synched to stunning footage of natural habitats and species, performed by string quartet Vesper and multi-million selling vocal group G4.

Ahead of the event, NHBS colleague Laura had a chat with Emma Marsh, the Executive Director for Digital Technology and Communications for the RSPB. In our interview, Emma shared details about this one-off live event, including its importance, what it represents and what she hopes people will take home and remember long after the concert is over. She also offered insights on her role, as well as the priorities and challenges for the charity.

Firstly, can you tell us a little bit about yourself and your role at the RSPB?

I was brought up on a farm in the Midlands (of England, UK) where my dad was a farm worker. I spent my childhood days exploring the fields, hedges and trees. I remember such a sense of freedom and the abundance of nature. That all changed as I grew older. Agricultural practices intensified and I watched the depletion of wildlife in front of me. That feeling of loss stayed with me and has driven my passion for conservation ever since.

My route into a conservation career was definitely not ‘standard’. My parents wanted me to be the first member of our extended family to go to university and a degree in International Relations, including the international politics of the environment, was my next step. I then navigated a route through the public sector, the commercial world in technology and finally landed in charity. I spent ten years in the waste and recycling sector, focusing on delivering behaviour change around food waste, which led to where I wanted and needed to be – in nature conservation and the incredible RSPB.

I joined RSPB in early 2016 as the Director for the Midlands, overseeing our network of landscapes, reserves, fundraising and comms, moving to be Director for the whole of England in 2019. In late 2022 I was able to bring together all of the experience I’d gained over the years, from Technology, to campaigning, to conservation, becoming the Executive Director for Digital Technology and Communications, sitting on the Executive Board.

Every day is different. One day I can be immersed in helping my team gear up our technology and media to deliver big events (such as Big Garden Bird Watch), the next pivoting and scaling up our comms and campaigning to unexpected legislative threats to nature, to speaking on the Radio 4 Today programme or R5Live about the incredible successes our teams have had with bringing threatened species like the Crane back from the brink of extinction. Another day I’ll be deeply immersed in developing the RSPBs strategy and reporting impact against it, the next working with Trustees, and when I’m really lucky it will be spent at one of our incredible 200+ nature reserves, seeing the spectacular conservation delivery and engagement that our teams do so well. It’s such a varied, dynamic and interesting role leading and working with some brilliant people – I’m incredibly lucky.

The RSPB has been around since 1889, and over the years it has developed and grown significantly. What would you say are its current priorities for nature, and where do you see the organisation going?

Emily Williamson, Etta Lemon and Eliza Phillips started the RSPB in the late 19th century, and the campaign they ran to ban the plumage trade (which was putting 60 bird species at risk of extinction) took three decades before it bore fruition. The tenacity and determination they demonstrated, when societal norms were stacked against them, was inspirational. When they started their campaign, women didn’t even have the vote, but they were convinced they could put an end to the trade, and they did. For me this determination and tenacity runs through the RSPB to this day. They used every tool at their disposal, just as we do today, campaigning with the public to drive awareness and support, engaging with politicians to drive legislative change and using science to gain credibility.

Our world-leading research allows us to take a bird’s eye view of the overarching problems facing nature and then pinpoint solutions that make a real difference. The world around us and the threats to birds and wildlife has changed significantly since the RSPB was created and so we have had to constantly evolve and change. Today we’re the UK’s largest nature conservation charity, with nearly 1.2 million members. We manage more than 200 nature reserves across all four countries of the UK, covering an area the size of 250,000 football pitches, making us the UK’s 5th largest landowner. Across those landscapes over 18,700 different species have been recorded. 85% of our workforce are volunteers, spending 1 million hours acting for nature every year. And we now have over 130 local groups spread right across the UK, connecting people and progressing conservation projects. We want to grow the number of people engaging with us as members, supporters, donors, volunteers, all taking action so that we can achieve a shared world where wildlife, wild places and all people thrive together. To do that we need to protect and restore habitats and landscapes, save species, help end the nature crisis, and inspire others to do the same. That’s a big ask but if anyone can do it, we can.

In particular in the UK our priorities are around demonstrating the art of the possible in terms of conservation on our nature reserves, and influencing nature-positive management at scale through partnerships in our Priority Landscapes; Internationally working with and through the BirdLife International partnership to deliver significant positive conservation impacts around the world; working to reduce the harmful impacts of selected fisheries around the world and marine development in the UK; getting the most important places protected through strengthened policy, and tackling threats to priority species; working tirelessly to secure the future of threatened species; working in partnership with the farming community across the UK, providing evidence-based advice to farmers, Governments and businesses, demonstrating good practice and developing and promoting policy frameworks that would enable a fair transition to nature-friendly farming; advocating for new income streams for nature so more can be invested in species and habitat recovery; and continuing to engage and empower more, and more diverse, people to take meaningful action alongside us to achieve all this. Ultimately, just like back in 1889, we think and act big. We deliver conservation you can see from space.

The Night of Nature concert seems like a new and exciting direction for RSPB engagement events. What inspired you to branch out?

Whilst Night of Nature is a bit of a first of its kind event for the RSPB, we nonetheless have a rich history of collaborating with voices from across the arts in order to bring nature to ever wider audiences. Back in 2022 we worked with international choreographer Sadeck Waff and agency 89up to create a ‘human murmuration’– a choreographed performance inspired by the stunning display birds put on as they flock together in a dance-like movement, emphasising the importance of working together to create impact. The murmuration was shown at COP15 where the Global Biodiversity Framework was agreed at the 11th hour. One of our current conservation milestones is the 50th anniversary of the re-introduction of White-tailed Eagles to the UK. To celebrate this achievement, we’ve partnered with acclaimed musician and sound artist Alice Boyd, who has just released a new track ‘Return of the White-Tailed Eagle’ (now streaming here) in tribute to the species. Alice also features – alongside RSPB ambassadors Dave Sexton and Nadeem Perera – in a forthcoming RSPB short film, ‘Return’, which documents the decades of conservation work by RSPB and our partners to bring the species back from the brink of extinction. ‘Return’ will release on August 29, with the trailer now streaming here.

We know just how important the voices of the creative community are to articulating the stories that drive our conservation work, and we’re thrilled to develop this relationship even further with Night of Nature.

Can you tell us a bit about the concert and what people can look forward to?

Night of Nature will blend live music with a cinematic celebration of nature. Stunning footage of the incredible species and habitats that we’re working to safeguard will be showcased on the Troxy’s big screen, synched to performances from #1-charting vocal group G4 and the Vesper string quartet. The evening will be hosted by RSPB Ambassador, actor/director Samuel West.

Think of this as a red-carpet experience—without the red-carpet price tag. With tickets starting at just £28, guests can enjoy an unforgettable show, mingle with our team, and even pose for a photo on the red carpet. It’s excitement, and entertainment—all within reach.

You have some exciting names attached to this event, how did they come to be involved?

G4 was a natural choice for Night of Nature. With their stunning harmonies and emotive performances, they bring a powerful sense of atmosphere to every stage they grace. But beyond the music, what really drew us to G4 was their genuine appreciation for the natural world. That really matters to us.

As a group that tours extensively across the UK and Ireland, G4 have had the chance to experience some of the country’s most breathtaking landscapes—from the dramatic coastlines of Scotland to the peaceful beaches of Devon, the wild beauty of Ireland, and the rolling hills of Yorkshire. Along the way, they make a point of pausing to soak in the scenery and observe the wildlife around them—often sharing these moments and photos with their fans on social media. It’s a window into the quieter, more reflective side of life on tour, and a reminder of how closely nature and creativity are intertwined.

With families of their own, the band feel a deepening responsibility to protect these places—not just for today, but for the generations that follow. When invited to take part in Night of Nature, they were immediately drawn to the idea of using music to celebrate the beauty of our world and support the vital work of the RSPB. For G4, this event is more than a performance—it’s a chance to help inspire others to cherish and protect the natural world.

Samuel West is an actor (currently playing Siegfried Farnon in All Creatures Great and Small on Channel 5) and director, and a keen birder for nearly twenty years. Speaking about his connection to RSPB and its work, Samuel says; “Until birds get their act together and organise their own pressure groups, I suppose we’ll just have to do it for them. With nature under unprecedented attack, the RSPB shows those in power what a huge and vocal nature lobby can do to change things. Our two young daughters love nature, and watching birds in particular. But the world they’ll inherit is in trouble. Half of all bird species worldwide are in decline. Biodiversity isn’t just a nice thing to have, it’s essential for the survival of humanity and the planet.”

Accessibility and connection to nature appear to be key inspirations for this event. What are you hoping to achieve with the Night of Nature concert?

In essence, Night of Nature is our way of saying a very heartfelt ‘thank you’ to all our members and supporters for their backing, without which we wouldn’t be able to deliver the vital work needed to protect and maintain the stunning array of species and habitats you’ll experience up on the Troxy’s big screen.

But we also know that we need more people to join us in taking action for nature. So we hope this also inspires even more people to come along and be a part of something bigger. Whatever you do – big or small – matters. It all joins up to create real and lasting change. Furthermore, research also demonstrates that connection to nature is in turn good for our own mental & physical well-being. Good for people and good for nature.

It’s our hope that Night of Nature galvanises even more of us to join the fight against biodiversity loss and work to tackle the climate crisis, as we strive towards a shared world, where wildlife, wild places and people all thrive alongside each other.

Progress towards the recognition of ecocide as an international crime

A motion (motion 061), supported by the Wildlife trusts among other environmental groups, invites IUCN members to support the recognition of ecocide as an international crime. Supporters, including wildlife trusts CEO Craig Bennett, argue that recognition would ensure that no actor can cause severe, widespread or long-term harm to nature without facing criminal consequences. Proponents have argued for decades (including a notable 10-year campaign led by barrister and green ambassador Polly Higgins) that international recognition of ecocide as a crime is essential if we are to collectively mitigate global environmental crises and protect nature. The motion will be considered at the next IUCN World Conservation Congress, set to take place in Abu Dhabi, UAE, in October.

Restrictions on the use of lead ammunition in Britain

Almost all shotgun pellets and bullets containing lead are to be banned in the UK under restrictions which will be phased in between 2025- 2028. The persistence of the usage of lead in shooting has led to the death of an estimated 100,000 waterfowl each year, alongside countless other grit-eating birds, raptors and scavengers. The new restrictions have been welcomed by environmental groups and are consequent to a decades long campaign. The story up to this point was covered in British Wildlife Volume 36.4.

The global impact of chronic oiling

The Guardian and Watershed Investigations have revealed damning statistics which underly a lack of understanding of the extent of oil spills in global seas. Extensive research, through the analysis of hundreds of thousands of satellite images over a five-year period shows that only 474 of more than 90,000 oil slicks from ships were reported to authorities between 2014 and 2019. The figures suggest that the extent of anthropogenic oil pollution has been grossly underestimated.

Lost jellyfish rediscovered

A species of stalked jellyfish, Depastrum cyathiforme, that had not been seen anywhere globally for more than 40 years and had never captured on camera has reemerged in the Outer Hebrides.

Naturalist, Neil Roberts, took the first photographs of the thistle shaped jellyfish in 2023. Its rediscovery, revealed by British Wildlife magazine, has been confirmed by a follow-up search that successfully located another individual. Marine naturalists have called for further exploration to establish whether populations exist outside of South Uist, around wider Britain and mainland Europe.

EBHL Conference – Paris, May 2025

NHBS colleague Leon recently attended the general meeting of the European Botanical and Horticultural Libraries Group, or EBHL for short, which this year took place in Paris from May 14th to 17th. This annual conference brought together librarians and archivists from academic libraries and herbaria for several days of talks and behind-the-scenes tours at four outstanding locations in Paris. We have attended previous meetings in Brussels and London, and this continues to be a valuable occasion to meet some of our key customers from across Europe and the USA in person. The overarching theme of this year’s meeting was “Plant Sources;” branching out into three topic areas over three consecutive days.

A view of the Jardin des Plantes and part of the Paris Natural History Museum.

Day 1

The first day took place just outside the Paris Natural History Museum and its botanical gardens and discussed new tools for botanical and horticultural documentation. This included approaches to preserving the illustrations in the herbarium of Bonpland and Humboldt, how bibliographic metadata reflects historical developments in taxonomy, and an introduction to World Flora Online, a global resource for botanical information. After lunch, delegates were split into several groups and taken around the special collections section of the Central Library, which featured a collection of remarkable historical wax models of fruit and fungi that were used in teaching. We were also amazed to see the museum’s restorators at work in the basement’s book and paper restoration workshop, surrounded by a collection of vintage hand tools and presses. The craft and skill on display here were, frankly, astonishing. The day was completed by a trip around the botany library and its enormous herbarium storing dried plant specimens, including some remarkable collections of original herbaria and exsiccata from Humboldt and other historical collectors.

On Wednesday, the conference continued at the Institut de France in the heart of Paris, right next to the Seine, and discussed private herbaria. A series of talks introduced us to some remarkable historical figures, including Benjamin Delessert, the Girardin family, and the tragically short-lived Auguste Pervillé, who died aged 33. Details of their lives and the impact they have had on the history of botany are ongoing areas of research. After a brief tour of the stunning library of the Institut de France, we were expected back at the Natural History Museum for a guided tour of its famed Jardin des Plantes. After this, I had the opportunity for a quick visit to the museum’s comparative zoology and palaeontology galleries, which have been high on my bucket list for Paris. The group reconvened in the evening at a rather unique venue, the moored barge “L’Eau et les Rêves” that doubles up as a floating café and Paris’s only botanical bookstore.

Day 3

Given the meeting’s theme for the third day, “Understanding French Horticulture”, we were originally supposed to convene at the Société Nationale d’Horticulture de France (SNHF) but, due to ongoing building and restoration works, were instead hosted at the Ácademie d’Agriculture. After being greeted by a bust of none other than Louis Pasteur, we listened to presentations from visiting scholars on, amongst others, SNHF’s historical bulletins and what they reveal about how horticulture grew and developed in France, the remarkable early-20th century autochrome and film collection of the Albert Kahn gardens (subject of the book Natures Vivantes), and the botanical iconography that can be found in the Decorative Arts Library. The latter was a visually rich talk on how botany has influenced ornaments used in print and sculpture.

One of the beautiful libraries in the French Senate.

In the afternoon, we were allowed access to several libraries inside the French Senate and taken on a tour of the adjacent gardens, the famed Jardin du Luxembourg. In the evening, we went back to the academy for a remarkable presentation of the book Les Raisins de Redouté, which reproduces historical paintings of grapes and grapevines. After having gone missing for over a century, this collection of 83 paintings on vellum was rediscovered in the academy’s archives in 2018 and reproduced in this handsome, large-format book while the originals, valued at some 6 million euros, have been stored in safer environs.

Day 4

The final day of the EBHL conference entailed a visit to Versailles, specifically to the Potager du Roi, the King’s vegetable garden, and the library of the adjacent École Nationale Supérieure de Paysage. This working garden used to supply food to the courtiers at Versailles at a time when year-round availability of fresh fruit and vegetables was still largely unheard of. The garden is in the process of being restored and has a long and storied history. In the library, the archivists treated us to numerous original maps from their collections that show plans of this and other gardens in Paris.

The meeting was a great opportunity to catch up with existing customers and hear what their institutes are up to. We are looking forward to the next meeting and would like to thank the organizers of this year’s conference, in particular Florence Tessier, Sabrina Castandet-Le Bris, Mégane Pulby, and Audrey Lumière.

NHBS welcomes opportunities to develop closer ties with the professional and amateur organisations that we count amongst our customers, whether through attendance or sponsorship. Do not hesitate to reach out to us.

A weekend of mammal discovery: my experience at the Mammal Society’s new residential training course

Course attendees learning small mammal survey techniques at the Field Studies Council’s Preston Montford activity centre

In the lead-up to this year’s National Mammal Week (21st-27th April), NHBS was kindly invited by the Mammal Society a preview of their new Mammal Identification and Ecology residential training course.

The Mammal Society is an active charity and learned society dedicated to the study and conservation of all British mammals. Founded in 1954, the organisation plays a crucial role in promoting research, education, and advocacy for mammal conservation. The Mammal Society works closely with scientists, policymakers, and the public to gather data, inform policy, and raise awareness about the importance of preserving Britain’s mammals species. The society’s efforts are vital in addressing the challenges faced by mammals, including habitat loss, climate change, and human activities.

A golden ticket

I was fortunate enough to receive the golden ticket to this enriching experience – a preview of a new immersive, hands-on training course focused on British mammals. Heading to Field Studies Council (FSC) Preston Montford activity centre, I was looking forward to engaging with ecologists, conservationists, and enthusiasts, all united by their passion for conserving UK mammal populations. I was also excited to gain insights into the equipment and methods used for monitoring mammals and to enhance my own identification skills.

The training course aimed to introduce participants to the skills needed for mammal identification and help us familiarise ourselves with various monitoring methods. These skills are crucial for accurately tracking population trends, population movements, and the factors influencing changes in conservation status. With one in four mammal species threatened with extinction in Britain, gathering detailed data is more important than ever.

The FSC’s centre, surrounded by fields, woodland, ponds, and the nearby River Wye, provided an ideal backdrop for a mix of fieldwork and classroom-based learning. With the added presence of an evening bar, this was a most appropriate venue where course participants could exchange their thoughts and evaluations.

Diving into mammal identification

The course kicked off on Friday evening with a hands-on session preparing Longworth Small Mammal Traps. We strategically placed 40 traps in an area of mixed habitat (the more traps you put out the better the chances of success). We added hay to each trap and baited them with seeds and blowfly pupae to attract rodents and shrews. The next morning, our efforts were rewarded with the capture of a Wood Mouse and a Common Shrew. It was fascinating to learn about the shrew’s high metabolic rate and the importance of providing food in the traps.

Additional monitoring methods included audio recording equipment, a Mammal Footprint Tunnel, and an improvised close-focus camera trap. The overnight footage from the camera revealed some curious Rabbits, adding to the excitement of our findings.

Classroom insights and field adventures

Saturday was packed with classroom sessions in a room that had been kitted out with mammal skins, skulls, nests, owl pellets, droppings and publications. The morning session was devoted to gaining a deeper understanding of small mammals and their ecological roles. The afternoon session focused on herbivores, teaching us how to identify the six species of deer in the UK and recognise signs of Wild Boar presence, such as uprooted turf.

A highlight of the day was the field session, where we searched for signs of mammal activity. From tunnels through grass and soil to footprints, droppings and gnawed hazelnuts, the landscape was teeming with evidence of our furry neighbours. The evening session on carnivores was equally engaging, with discussions on the UK’s mustelids, the elusive Wildcat, and the controversies surrounding mammal persecution and reintroduction.

The evening concluded with a session on bats, followed by a thrilling field trip with bat detectors and thermal imaging monoculars.

Sunday morning saw us checking the results from our field monitoring equipment. The most challenging part for me was the classroom session on tracks and signs, where I struggled with a footprint quiz. Dissecting owl pellets was a unique experience, revealing the remains a Field Vole and a Common Shrew in the pellet I looked at.

The final session covered sea mammals, such as dolphins, whales and seals after which a weekend of comprehensive learning was rounded off with a course evaluation.

Post-event musings

The Mammal Society’s training course was an invaluable experience, combining hands-on fieldwork with insightful classroom sessions. I returned with a deeper understanding of the diversity and complexity of the UK’s mammals, as well as the importance of ongoing conservation efforts. Equally, I gained a refreshed appreciation for the profound knowledge and dedication of the members of the Mammal Society. I also learned about some handy wildlife recording apps, such as the Mammal Society’s own Mammal Mapper, and iRecord for all biological recording. Whether you’re a seasoned ecologist or a curious enthusiast, you’re sure to return from this training enlightened and motivated.

Author interview with Trevor Dines on Urban Plants

The 15^th volume in the insightful British Wildlife Collection is this timely and illuminating journey into the wild lives of Urban Plants. In this book, Trevor Dines explores the floral species that pioneer our pavements and walls, break ground in our towns and cities and strive to connect corridors for pollinating invertebrates through our built-up landscapes. Trevor also looks to the future and the potential impacts of invasive species, herbicides and climate change, as well as the concept of urban rewilding.

Trevor Dines, a farmer’s son from Hampshire, co-authored the New Atlas of the British and Irish Flora, mapping every native and naturalised plant in these islands. A campaigner for better management of road verges and lawns and the creation of wildflower meadows, he appears regularly on the Radio 4 Today programme, BBC Breakfast and Countryfile. Trevor also presented Channel 4’s Wild Things and wrote the accompanying book The Wild Things: Guide to the Changing Plant Life of the British Isles.

We recently had the pleasure of asking Trevor more about why and how he came to write Urban Plants

Firstly, can you tell us a little about yourself and how you came to write the 15th volume in the renowned British Wildlife Collection?

I was incredibly lucky to grow up on two farms -one in Wiltshire and another in Hampshire -where I developed a deep passion for wild plants. I’d spend hours searching dad’s fields for rare arable flowers like Venus’s-looking-glass and Rough Poppy, as well as orchids on the chalk downland. After leaving Bangor University with a PhD in plant architecture, I worked for the Botanical Society of Britain and Ireland, co-authoring the New Atlas of the British and Irish Flora (2002). This is when I really got to know our flora, travelling the length and breadth of the country meeting plants and the network of incredibly talented plant recorders that are so happy to share their knowledge. For 20 years I then worked for Plantlife – the plant conservation charity – in particular championing the creation of wildflower meadows, the better management of road verges, and changing attitudes towards lawns through the invention of No Mow May.

During this time, I also presented a Channel 4 TV series (Wild Things) that showed how and why plants are changing their distributions around Britain and Ireland. This led to more work in the communications side of things at Plantlife, something I’ve always had a passion for because it’s such an important element of conservation. This was an exciting time, with appearances on BBC Countryfile, BBC Breakfast and Gardeners’ World, as well as many local radio and newspaper interviews and writing articles for magazines. Katy Roper, Commissioning Editor at Bloomsbury Wildlife, became aware of my work through an item I’d written about the spread of Oxford Ragwort and invited me to consider writing a book on urban plants for the series. I was, of course, thrilled at the prospect, and threw myself into the project in 2022 when I became a freelance botanist.

Flowers in a Conwy street by Trevor Dines

My favourite excerpt from the book was hearing about the newly established population of Lesser Tongue-orchids thriving on the roof of a large city bank. Do you have a favourite, but possibly less well-known, urban botanical enclave you can share with us?

I particularly enjoy finding mundane or even rather grotty places with completely unexpected plants. Between a footbridge and the railway into my local town, Conwy, for example, there’s a thin sliver of fallow waste ground that’s home to a very bizarre mix of plants. Alongside the usual suspects like Buddleja and Oxford Ragwort, bright pink Pyramidal Orchid and Zigzag Clover push up between clumps of Pampas Grass, an increasingly invasive garden escape from South America. And, for the last few years, Iris reticulata × histrioides ‘George’ has also flowered here, the only place in Britain where it’s known to be established outside gardens. Tantalisingly, all these plants are unreachable behind a metal fence, adding another level of challenge for the urban botanist.

There has been a sad decline in the number of higher education courses offering botany as an option. However, with the news of the natural history GCSE coming this year, how would you integrate uUrban botany into the course as a way to encourage future botanists?

Urban botany is unique in being accessible to everyone, everywhere. You don’t need to travel to a nature reserve, a woodland, a meadow or other special place to engage with it – it’s quite literally right there on your doorstep. This makes it an ideal subject for the new GCSE, and there are lots of opportunities. Students could look at the phenology of flowering through the year, counting the number of flowers in a given area from the first Dandelions and Groundsel of the year to Herb-Robert and Red Dead-nettle at Easter, and finally Red Valerian and Purple Toadflax before the end of term. Or they could study local walls, seeing how the vegetation varies according to building materials and the direction the wall faces. Or they could look at the impact of footfall on pavements, with fewer plants in areas having most pedestrian traffic. The important thing is that urban plants are fascinating because every species has a story to tell; I love the reaction from kids when you tell them that germinating seeds of Shepherd’s-purse actually kill nematodes to help them survive. It helps bring their environment alive (unless you’re a nematode!).

Rewilding is a hot topic in conservation and biodiversity, and No Mow May is a growing campaign many partake in. Can we ‘rewild’ our immediate environment with this changing mindset to benefit urban plants and biodiversity?

I’m glad you’ve put ‘rewild’ in quotes, as it’s become such a diluted phrase – it now seems to cover any conservation action, from planting wildflowers in a window box to reintroducing beavers. Rewilding in its original form (the reintroduction of charismatic mammals to kick-start natural processes) is very difficult to do in urban areas because habitats are so fragmented and anthropogenic pressures are so high. As engaging as they are, I’m afraid beavers can’t do much to improve the diversity of life in the built environment.

But for many people, rewilding simply means reining back on the intensity of management (or even abandoning management at all) and just letting things grow, seed and recover. And in this case, yes, it’s what the urban environment desperately needs. As the creator of the No Mow May campaign, it’s fantastic to see how this approach has captured people’s imaginations and encouraged us to put the mower away, hopefully not just for May but the whole of summer. The results can be spectacular, with orchids appearing on lawns and mini-meadows with carpets of White Clover, Selfheal, Bird’s-foot-trefoil and buttercups.

Urban biodiversity is all about the tension between our desire for control – an environment kept ‘neat and tidy’ through the use of herbicides, mowing and strimming – and our desire for something wilder. We are, I think, still exploring this relationship, trying to become more comfortable with ‘messier’ streets. Many towns and cities are relaxing their use of herbicides and allowing more vegetation to grow, but then often face a backlash from the neat-and-tidy brigade. Hopefully, as is the case in much of Europe, we’ll become more relaxed in the future and begin to embrace more flowers on our streets in the future.

You discuss how the successional stages of our urban landscape provide a unique opportunity for plants from around the world, which is a win for cosmopolitan biodiversity. What can we learn as individuals from the resilience of this vast array of plant life?

I think botanists inherently appreciate that diversity is not just a good thing, but the very foundation of resilience. Each species has its own suite of unique characteristics that help it survive – be it tolerance of drought or pollution, the ability to set seed within just a few weeks, or a particularly successful method of dispersal – and building communities of plants with these different traits helps them survive the intense stresses of the urban environment. We humans are just the same; we are all different, we all have different skills and talents, and we all bring something unique to the party. And if we come together and draw strength from our diversity, we’re much more likely to cope with the everyday stresses of urban life.

Finally, what’s taking up your time at the moment? Are there any other projects you’re working on that we can hear about?

I’m currently working for the Species Recovery Trust, a small but brilliant charity that’s dedicated to the long-term survival and recovery of a suite of highly threatened species. Alongside traditional conservation subjects like Field Gentian and Forked Spleenwort, I’ve just started working on Welsh Groundsel (Senecio cambrensis) – a hybrid between Oxford Ragwort and Common Groundsel. This unique endemic species is only found in north Wales where it grows along pavement edges, roadside hedgerows and on waste ground, usually in urban settings. Unfortunately, it’s fallen victim to the neat-and-tidy brigade, having been lost from dozens of sites due to herbicides and strimming. It’s now only known from five places and is on the brink of extinction, so we have a lot of work to do to bring it back. But I relish this sort of challenge and hopefully we can recover some lost populations in the next few years.

Author interview with Michael J Warren: The Cuckoo’s Lea

Weaving together early literature, history and ornithology, The Cuckoo’s Lea takes the reader on a journey into the past to contemplate the nature and heritage of ancient landscapes. It explores the stories behind our placenames, alongside historical accounts of bird encounters thousands of years ago, their hidden secrets, the nature of places and more.

Michael J. Warren is a naturalist and nature writing author who teaches English at a school in Chelmsford. He was an honorary research fellow at Birbeck Colledge, curates The Birds and Place Project, and is a series editor of Medieval Ecocriticisms. We recently had the opportunity to speak to Michael about The Cuckoo’s Lea, including how he first became interested in birding, what he discovered throughout his research for this book and more.

Firstly, can you tell us a little bit about yourself, and how you became interested in birds and birding?

Professionally I do many different things, but birds, the natural world, conservation and environmentalism are central to all of it. I’m an English school teacher as well as an academic working in the environmental humanities (my PhD was on birds in medieval poetry), so literature, language and history are always intertwined with my love of nature and nature writing. I was formerly chair of the New Networks for Nature group and am currently a trustee for the charity Curlew Action, where I advise on education as it relates to the forthcoming Natural History GCSE.

I’ve been into birds and birding for as long as I can remember, having been encouraged by my uncle and aunt who are both keen naturalists themselves, but most of all I was inspired by my parents as they did one of the best things I think any parent can do for a child – they educated me in the great outdoors. By which, I meant that all our holidays were in various wild locations across the UK, involving ramshackle cottages in remote valleys and by secluded rivers, from which my brothers and I were free to roam, exploring and playing each morning. I have a deep passion for British landscapes and wildlife, and I am who I am today because of those early experiences. They shaped me profoundly, and I’m now trying to do the same with my two daughters (which is working so far, but they’re still young and impressionable right now!)

What inspired you to write a book on the history of place names with avian origins?

Initially this idea came from my academic research on birds in medieval literature and culture. When I started to explore the presence of bird species in place names – in the realm of medieval studies by default as most English place names are Old English in origin and can be traced back to the Middle Ages – I was astounded by just how many there were. I knew there was something really fascinating to examine, including what these names could tell us about people’s ecological knowledge and relationships over one thousand years ago. Every name is a story.

One of my reviewers has kindly described The Cuckoo’s Lea as a ‘Rosetta stone for our ecological knowledge’, but it’s the place-names that are the stone. They provide us with a portal into the imagination of early people who were encountering and interacting with these environments. I realised that placenames were the perfect subject for my first narrative nonfiction book as it combines birds, landscapes, medieval history and ecological history, while also providing the opportunity for me to travel to different places, experience them first hand, and collate all these elements into a personal narrative with broad appeal.

Each chapter focuses on a different location and species across the UK. How did you decide which areas to focus on and which of the many species that reside there to highlight?

I went back to the drawing board a lot with that one!

I wrote this book alongside becoming a father: six years of raising two daughters through those early years combined with six years of research, travel, and writing at 4am in the morning because that was the only way to carve out writing time until I got my book deal with Bloomsbury. As such, practicality determined a lot of it – I travelled to locations I could feasibly reach within my budget (at one point we were living on my part-time salary and my wife’s statutory maternity pay) and the restricted time available. Under other circumstances I would have liked to have travelled farther afield for the book – to Ireland, for instance.

My selection was also determined by the range of species that I thought would most appeal to readers. So, although there’s a danger of over-featuring certain birds in nature writing, I knew I had to include cuckoos, cranes and nightingales in the book because everyone loves them! These three species were also popular in medieval culture too, so it made sense to feature them, and I lived in Cranbrook (Kent) for most of the time I was writing the book, so that provided an obvious starting point.

I also thought hard about the range of ideas I wanted to explore relating to how birds evoke and define place for us and allowed this to lead me towards particular birds and/or places. For instance, I wanted to write about the soundscape of birds as a phenomenon that both animates or shapes place – a recurring idea in the book. This meant that owls became important as, to me, they exemplify this enthralling idea that our ancestors naturally and happily recognised bioacoustics as distinguishing properties of a place’s atmosphere. Finally, and again practically, it was also imperative to have some geographical range to my adventures so any reader would be able to read about somewhere in their home county or a nearby county.

What was the most surprising discovery you made whilst researching this book?

I think it was the sheer number of species represented in Old English placenames.

I don’t think you would expect birds to turn up so frequently in placenames, given that you’d want a place-marker or identifier to be reliably solid, present and static – and birds don’t tend to remain static much of the time. Some of the species that can be found in our placenames, such as swallows and cuckoos, aren’t even in Britain for much of the year! On this basis, wrens, buntings, snipe, dunnocks and sparrows aren’t species I expected to find.

There’s also nowhere that really matches the range of species in English placenames. Gaelic does have a good range across both Ireland and Scotland, but it’s difficult to trace the origins of the names beyond the 19th or 18th centuries as the cultures were oral, so names often weren’t recorded until the first OS maps were produced.

On the flip side, I was also surprised by the species that aren’t in our place-names – nightingales, for instance. This species was highly prominent and celebrated in both medieval art and poetry, and would have been much more populous than they are today, so how is it that they didn’t find their way into placenames? (That doesn’t stop me having a chapter on nightingales, by the way.) The same goes for corncrakes. There was an Old English name for the bird, and their calls would have undoubtedly been an unavoidable and loud sound of summer throughout the land. Herons only appear once or twice, and, perhaps most surprisingly, the robin (or ruddock in Old English) doesn’t feature at all!

Finally, can you tell us what you’re working on at the moment?

Right now, I’m focused on making a success of The Cuckoo’s Lea!

Alongside booking readings, signings and talks, I’m also creating a website titled The Birds and Place Project (birdsandplace.co.uk) which aims to record the birdsong of all the species mentioned in English placenames – which is quite an undertaking! It will be a lifelong project as I’d like to extend it beyond England and the English language to include other countries and languages found across Britain and Ireland. I see it as an extension of my book; and as a site for anyone to find out about this fascinating, but currently little-known, aspect of our natural history and heritage.

Beyond that, I’ve got my eye on my second book, provisionally titled Hibernal: The Obsessions of a Justified Winter Lover. I’m a serious winter fanatic, so I’ve known for some time that my second book will be a meditation on my favourite season. It will be an emotional and personal journey into my obsession with winter, including encounters with those living and surviving the season in the far north, as well as those who can’t stand winter and suffer terribly in the darkness and cold. Plus, it will highlight historical stories about the importance of winter, how previous times and cultures coped with it, and discuss how winter as a season is changing because of climate change. I don’t think there’s much chance of me commencing this book in 2025, but then again, if this book is going to take me another six years, I can’t waste a single winter…

#NoMowMay 2025

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.

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!

Celebrating 40 Years of NHBS: A journey of passion and commitment to natural history and the environment

NHBS is proud to celebrate its 40th anniversary, marking four decades of supporting those who work to understand, protect, and conserve the natural environment.

History of NHBS

Founded by Bernard Mercer in 1985 as the Natural History Book Service, NHBS began as a mail-order supplier of ornithology books based in London. Our first catalogue was hand-crafted on a state-of-the-art electronic typewriter! Within two years, we evolved into a comprehensive natural history bookstore, committed to supplying all in-print literature on both natural history and science. Shortly after, we relocated to Totnes in Devon, and we have remained here on the edge of the River Dart ever since.

By the late 1980s, in response to customer demand, NHBS expanded its subject range to include habitat and species conservation, climate change, environmental assessment and more. In May 1995, we ventured online with the launch of our first website, and as digital communication grew, our website and email newsletters became increasingly important, leading to our final newspaper catalogue in 2005.

At the start of the new millennium, NHBS began expanding its range to include products such as bat detectors, trail cameras and moth traps, having recognised the growing demand for nature-based equipment. Today, we offer a comprehensive range of books and practical equipment for ecologists, researchers, educational professionals, and wildlife enthusiasts alike.

“Celebrating 40 years is a testament to the dedication and passion of our team and the unwavering support of our customers. We are committed to continuing our mission to provide the best resources and tools for those who strive to protect and understand our natural world.”

Bernard Mercer – Founder and owner

NHBS Around the World

NHBS’s global customer base has led to us sending products to even the most remote corners of the world. These include the Black River in Mauritius, Ascension Island, Benbecula in the Hebrides and Mount Athos in Greece. Our parcels have reached over 140 countries, supporting researchers, educators, and conservationists wherever they are based.

The NHBS Mission

Since we began in the 1980s, our core purpose has been to support individuals and organisations working to understand, protect, and conserve the natural environment.

Forty years on, this continues to drive us, shaping our decisions and inspiring our ongoing work in the conservation world.

We’re have collaborated with a wide range of leading NGOs such as Butterfly Conservation, The Riverfly Partnership and Buglife, and to date, we have donated over £35,000 to support their vital work. In 1999 we also developed the Gratis Book Scheme, which was launched alongside the British Ecological Society and successfully delivered hundreds of books free of charge to students living in developing countries.

Thank you and Looking Ahead

As we reflect on the past 40 years, we’re grateful for our valued customers and the countless individuals and organisations we’ve had the privilege of supporting. We are proud to have forged close partnerships with many conservation organisations who share our values – the Mammal Society, Butterfly Conservation, Bat Conservation Trust and CIEEM, to name just a few, and we look forward to working together to better British conservation.

Looking ahead, we are excited about the future of NHBS and the continued pursuit to fulfil our mission to empower and support those working in conservation.

Thank you for being part of our journey and we look forward to the next 40 years!

Equipment in Focus: CHASING Underwater Drones

CHASING’s range of underwater drones (also known as Remotely Operated Underwater Vehicles – ROUVs) includes high-end consumer and heavy duty industrial-grade models. The drones capture high resolution underwater images and video, allowing unobtrusive, accessible monitoring, surveying or exploration of aquatic spaces. With technological applications ranging from reef monitoring and marine ecological assessments to aquacultural inspection and general exploration, these innovative devices are a powerful tool for efficient data collection and observation.

Underwater drones can alleviate health and safety concerns, save time, money, resources and the need for specialist personnel. By providing high-resolution imagery and precise manoeuvrability, this technology allows for the safe, efficient observation and sampling of aquatic environments whilst minimising harm or disturbance.

In this blog, we introduce you to CHASING’s underwater drones – the Gladius Mini S, the M2 S, M2 PRO and the M2 PRO MAX.

Consumer Models

Gladius Mini S

The Gladius Mini S is a highly portable consumer-grade drone for underwater exploration. Quick to deploy, with a maximum operating time of around four hours, the Gladius Mini S requires little preparation to get started and can be operated by one person– simply attach the tether, controller and accessories, and connect your mobile phone to the CHASING app. The Gladius can operate in temperatures between –10 and +45°C, and at depths up to 100m. High-quality video and still images are captured with the 4K image stabilised camera and powerful integrated lights, producing excellent underwater imagery. The Gladius Mini S has one mounting point, which can support accessories such as the grabber claw and underwater GoPro mount.

The Gladius Mini S is available in four packs: Standard pack with a 100m tether, Standard pack with a 200m tether, Flash pack containing grabber claw B and a 100m tether, and a Flash pack containing grabber claw B and a 200m tether.

Industrial Models

Alongside the consumer model, there are a number of industrial-grade drones that are better suited for larger scale projects – the CHASING M2 S, M2 PRO and the M2 PRO MAX. The main advantage of these models is the use of interchangeable batteries, additional accessories and an increased tether length for longer sessions. Each industrial model benefits from a 4K camera, up to 4 hours run time, 150° field of view, e-reel compatibility, and powerful vectored thrusters allowing for precise movement. Here, we explore these models a little further, outlining the differences between each drone and their benefits.

Find a summary of the M2 series specifications below:

CHASING M2 S

Marking the first step up from consumer models, the CHASING M2 S benefits from eight thrusters for maximum stability and a high response speed. The unit features multiple accessory ports that are suitable for grabber arms, distance lock sonars, laser scalers and floodlights, as well as third-party accessories such as GoPro cameras. With the ability to swap batteries, and a greater range of compatible accessories, the M2 S is equipped for longer sessions with increased capabilities. An upgraded colour restoration algorithm improves the image transparency, clarity, colour, layering and noise on the M2 S, and live feed can be streamed onto multiple devices.

Applications

Underwater drones, or ROUVs, provide an alternative, accessible tool for ecological and scientific research. Their applications extend far beyond observation, enabling researchers to conduct detailed ecosystem health evaluations, monitor invasive or threatened species, and perform habitat inspections – all with the capability to collect samples for off-site analysis. From assessing the source of underwater pollution, to conducting biodiversity surveys, these drones provide high-resolution imagery and real-time data, facilitating well-evidenced conservation action. Their ability to perform targeted water and physical sampling allows for detailed analysis of aquatic environments, which can reveal insights into aquatic biodiversity and ecosystem health.

Outside of its ecological applications, this technology has potential in search and rescue operations, item recovery, hull and dock inspection and energy facility inspection.
