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.

The NHBS Guide to UK Wasps

Often seen as mere picnic nuisances, the UK is home to a surprising variety of wasps, including both social and solitary species. While many of us will be familiar with the iconic black and yellow social wasps, numerous solitary species display incredible diversity in both form and behaviour. Distinguishing them can seem daunting, but key features like body shape, coloration, and reproductive behaviour can offer valuable clues.

Here, we’ll explore a selection of common wasp species, and some wasp families found across the UK, detailing their identifying characteristics and the typical habitats they can be found in.

**Common European Yellowjacket (*Vespa vulgaris***)

Identification: Between 11-19mm in length with striking black and yellow stripes. These social wasps have six abdominal sections, each with one stripe, and there is a very distinguished waist between the thorax and the abdomen, which has black dots and rings. The species has a conspicuous face on a triangular shaped head with a black anchor or dagger shaped mark towards the base, and a pair of long, robust antennae. They have yellow cheeks and yellow legs.

Distribution: Widespread throughout the UK. Common Social Wasps can be found in almost all habitats, particularly grassland, heathland and woodland from mid-March to November.

**Red Wasp (*Vespula rufa***)

Identification: Growing up to 20mm in length, Red Wasps can easily be distinguished from V. vulgaris by reddish-brown markings on their upper back segments.

Distribution: Widespread, and frequently found in open woodland, moorland and hedge banks from the end of March until September.

**Hornet (*Vespa crabro***)

Identification: Hornets are Britain’s largest social wasp species. Around 15-35mm in size. The abdomen is yellow and unbanded, with brown markings on the upper parts, while the thorax is black and reddish-brown. Their legs are a reddish brown – a characteristic that can distinguish them from Asian Hornets – and antennae are yellow or brown in colour.

Distribution: Widespread distribution and commonly found throughout England and Wales. Hornets can be found in many lowland habitats and are known to associate with ancient woodland, wood pasture and can be found in parks and gardens in more urban areas. Queens emerge from overwintering in early April, while workers can typically be seen from late June to November.

**Yellow-legged Asian Hornet (*Vespa velutina***)

Identification: Typically smaller than native hornets, this invasive species can grow up to 3cm in length. Their abdomen is dark in colour with fine yellow stripes, and the fourth segment towards the base of the hornet is distinctly yellow orange in colour, while the thorax is entirely black or dark brown and appears velvety in texture. From the front, the head appears orange and the legs have yellow tips.

Distribution: Yellow-legged Asian Hornets were first recorded in England around 2016, after they were accidentally introduced from Asia. They have mostly been recorded in the south of England, particularly the South-east.

Wasp Families

The diversity of wasp families in the UK is vast and presents a significant identification challenge. In this blog, we have chosen to focus on a number of wasp families to demonstrate the wonderful diversity of this group.

Ichneumon Wasps

There are around 2,500 species of Ichneumon wasp in the UK. These small insects can vary in size but generally reach up to 1 ½ inches in length. They exhibit a wide range of colours and patterns, some with brightly coloured bands, and others with more subtle markings. Ichneumon Wasps can be distinguished by a slender sickle-shaped abdomen and a pair of long antennae, each with at least 16 segments. They have a narrow waist, long jointed legs and two pairs of wings. These parasitic wasps inhabit flower-rich meadows, gardens and woodland – they can often be seen around umbellifers or investigating vegetation and dead wood.

Gall Wasps

The UK is estimated to have 86 Gall Wasps, a group of well-studied parasitic wasps. This group gets its name for a unique reproductive behaviour where adults lay eggs in the soft tissues of trees, flowers and other plants, creating a gall as the larva develop. Usually on the underside of leaves, branches and around acorns, these wasps produce conspicuous galls on their host plant – interestingly, they usually only infect a specific species of genus, for example, Citrus Gall Wasps will exclusively parasitise citrus trees. After overwintering, the larvae will emerge in spring and can be seen throughout summer. They are typically under 5mm in size, shiny, and are black or brown in colour with a humped thorax and wings.

Cuckoo Wasps

Instantly recognisable by their brilliant metallic body colours in shades of blue, green, purple and red, these small chrysidids are also known as jewel or ruby tailed wasps. There are around 31 species of Cuckoo Wasp in the UK, which can be seen in sunny weather from April to October in a range of habitats; particularly in sandy soils around coastal areas, gardens and ancient woodlands. The group are often seen investigating the nests of other Hymenoptera species in order to reproduce – these parasitic species will enter the host nest and lay their own eggs in the host cells. Once hatched, Cuckoo wasp larvae will eat the eggs and larvae of the host species before restarting the cycle – hence the name ‘cuckoo’.

Author interview with Seán Ronayne: Nature Boy

An inspiring story of love, connection and the healing power of nature, author Seán Ronayne recounts his journey to record all the regularly occurring species of birds in Ireland. He also tells the stories of his adventures across the Sahara Desert, the jungles of Nepal, and the streets of Thailand, revealing the wonders of the natural world.

Seán Ronayne is an ornithologist and naturalist who was born in Cork, Ireland. He spent his childhood exploring the fields and woodlands around his hometown, before studying Zoology at University College Cork, followed by a Master’s in Marine Biology. He secured his first ornithology role in 2017, before relocating to Barcelona with his partner where he began recording local wildlife and birds in earnest. Upon their return to Ireland in 2020, Seán embarked on a project to record all of Ireland’s birds, some of which are on the cusp of extinction, and he now has only three species left to record.

We recently had the opportunity to speak to Seán about Nature Boy, including what first sparked his interest in nature, which equipment he uses for sound recording and more.

In your book, you talk about how nature has been a constant source of comfort and curiosity for you. Do you remember when the natural world first began to resonate with you? Was there a key event which sparked your interest?

Yes! I have two standout moments, both of which are particularly special in different ways. I was a very active child, and I really mean that. I was always on the go, and if I couldn’t be on the go, I was wriggling, squirming, and crying – longing to be free. My father quickly learned that a foray into nature was the cure. He would take me to our local nature reserve and imitate the sounds of all the wildlife around us. I would belly laugh at his attempts and give him my best guess. It was a great game to me, but it was also an education in disguise – Dad was teaching me to listen to nature, and to get to know my neighbours by ear.

The other is my first memory of a bird. I was very young, around 2 years old off the top of my head, and the bird was pointed out to me by my Dad’s father – Pops. He loved birds too. I’ll never forget that first view of a magpie, with its regal pied plumage, draping long tail, and green and purple shimmying iridescence. Pops died not long after. I did not understand, but today, every time I see a magpie I see Pops, smile and thank him for the journey he sent me on.

Can you share with us what equipment you use for recording and what your decision process was for selecting it?

I am not a technical sound-recordist. I follow my ears, and my heart, and then I record the sounds that call to me with whatever tools I have at my disposal. I learned my skills through trial and error (mostly through error), but you know the phrase – even a broken-down clock is right twice a day! For isolating birds and getting a close intricate recording, I use a Dodotronic Hi-Sound parabolic reflector, paired with a second-hand Olympus LS-12 recorder – the Nokia 3210 of the sound recording world. To capture really intimate moments, or for longer, all weather deployments, I used a Song Meter Mini II. The sound is superb, and the device can be hidden easily, allowing birds to approach close and whisper into the mics unbeknownst to themselves. This provides intimate chitter-chatter I’d never otherwise get the opportunity to capture, and the Song Meter runs for weeks and can survive all manner of weather conditions! I guess these two pieces are my go-to tools.

Bioacoustics is one of the fastest-growing industries in the ecological sector. Are there any technological advances you’d like to see in this field?

I am really happy with where it’s at, to be honest! I can see that AI software to auto-identify birds is being worked on, but I don’t really care for that. I absolutely adore pouring through raw audio with a fine-tooth comb myself. In doing so, I enter that world, and I learn so much – a fast summary response kills the magic and learning for me. Perhaps others will disagree with me, but for my needs I am happy with where the technology is at, and the constant need for ‘progress’ in today’s world has a lot to answer for in terms of ecological, climate, and planetary degradation, after all.

While watching your documentary, I was very moved by your recording of the last known pair of Ring Ouzels in Ireland. Can you describe what it felt like to capture that moment, knowing you were recording a piece of history?

It was utterly devastating, and highly stressful. We’re talking about a bird that has been visiting our uplands each summer for hundreds, even thousands of years, wiped out in a heartbeat, with the majority of people not even knowing it existed at all. The stress came into the equation because I felt a strong desire, responsibility even, to capture its voice to show people the sonic beauty of what we are erasing, and what we need to stand up and fight for. With just one known pair remaining I was unsure if I had time to give this bird a voice, and if I didn’t capture it I’d have been doubly devastated – I’d have felt like I left it down, leaving it to die out in silence, unheard and forgotten. That did not happen though, at least.

Birdsong seems to have the ability to engage and move people in a way that perhaps other facets of nature don’t. Why do you think this is?

Well, I think it’s hard not to love it, isn’t it? Birdsong is nature’s melody! The dawn chorus is nature’s orchestra. It’s always there, it’s such a treat to listen to and it’s completely free. We have evolved in tandem with it. We hear birdsong, and everything is right with the world…we don’t hear birdsong, and something has gone terribly wrong. Right? A forest has been felled, a river has been covered, a bog has been drained, a city has enveloped, a motorway has drowned it out.

In your book, you talk about the importance you placed on your first bird ID guide as a child. Do you have any go-to books for bird identification?

This is easy – the Collins Bird Guide (the bible), and of course the legendary Sound Approach collection.

With your recent book, tour and documentary, you’ve made a real push to engage with the public and remind them of the natural world. What do you hope people take from your work?

I just hope that people realise how inexplicably beautiful, educational, nourishing, wondrous, and ever-giving nature is. But I also need them to know that it’s in freefall. Because of our own very actions. And inactions. My work is a call to arms, with hope and beauty being my primary weapons – with a brief but sharp slap of loss and despair. The latter is necessary, but it is my secondary weapon. Love and hope outgun loss and despair always.

You currently only have 3 species left to record to complete your mission to record every Irish bird. Do you have any plans for afterwards?

Of course. I will be on this journey for as long as I’m gifted time on this earth. Recording all of these birds was never intended to be a tick and run exercise. Every time I listen to a given species or individual I learn something new. I capture a new voice. The more I listen, the more I realise how little I know. And that’s gorgeous, isn’t it!? This is what I mean when I say that nature is ever-giving. And to answer you in more direct terms, I fully intend to write more, and to work on more film projects. I’ll also tour my talks, stories and sounds until people have had enough of me, which I hope never happens (haha)!

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.

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

Environment

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

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

Wet Farming

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

Policy

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

Book review: King Tyrant

***** Sets the standard for what good popular science can be

When Princeton University Press announced King Tyrant, I was beyond excited. Whether it is pterosaurs, palaeoart, or the Crystal Palace dinosaurs; whatever palaeontologist and palaeoartist Mark Witton writes on has been brilliant so far, and King Tyrant very much continues that tradition. Do not let the pretty pictures fool you; this is not a children’s book but a grounded, fact-based overview of the scientific consensus on all things Tyrannosaurus rex, combined with numerous informative diagrams and Witton’s gorgeous palaeoart. The execution of this book sets the standard for what good popular science can be and is a model that other authors and publishers can aspire to.

Even if you know nothing about dinosaurs, T. rex is the one name you will recognise, such is the fame of this extinct animal. Surely, books about it are a dime a dozen? In a recent interview on the Love in the Time of Chasmosaurs podcast, Witton pointed out that, surprisingly, this is not the case. Hone’s book covered the family at large, but, aside from two technical books in recent decades, the last popular treatment was Horner & Lessem’s book in 1993. That might just as well be prehistory, given how much research has advanced and how many more fossils have been found since then. This is a clear case of Witton writing the book that he wanted to read.

Given how frequently the name T. rex crops up, you might even get a bit annoyed: not you again! All the more reason to read this book. Witton is acutely aware that a veritable subculture has grown up around this one species that “sits, sometimes uncomfortably, on the boundary between science and sensationalism” (p. 1). These popular depictions, often carrying with them an air of scientific authority, bleed into people’s consciousness, creating something less of a dinosaur and more of a chimaera, with traits both exaggerated and fictional. One of Witton’s most important goals with King Tyrant is to “deconstruct hype and controversy” (p. 41). The first chapter daringly combines a précis of the first century of research with an examination of the sociological side. How did this particular species become palaeontology’s rock star? It is a fascinating history that starts at the American Museum of Natural History who promoted it to attract large crowds. It was “proverbial lightning in a bottle” (p. 278), with an influential legacy that lasts to this day in movies, documentaries, and merchandise. And yet, popular depictions “have nothing on what science tells us about the reality of Tyrannosaurus rex” (p. 279).

The bulk of the book thus explores what the science actually shows. The remaining six chapters flow logically into each other: the definition and taxonomy of the species; internal and external anatomy; physiology, growth, sensory biology, locomotion, etc. (i.e., what all this anatomy might have been capable of); ecology and behaviour; and extinction. Indeed, the writing is one of the two highlights of this book. Witton strikes that fine balance between going into quite some technical detail and yet keeping it entertaining. The result is a well-grounded and accessible summary of the scientific consensus on numerous topics.

T. rex, more than any other species, attracts a lot of fringe ideas from inside and outside of academia, and Witton leaves no rock unturned. On the one hand, there are the minority views and “non-troversies” (thanks Witton, I am stealing that brilliant term) that get far too much airtime, such as the existence (or not) of a dwarf species, “Nanotyrannus“, or the scavenging hypothesis, the notion that T. rex was a scavenger rather than a hunter. Needless to say, neither idea curries much favour among professionals. On the other hand, actual scientific debates are often ignored by the press. Opinions are divided on whether dinosaurs were already on their way out before the asteroid impact or were still in their prime. Witton provides the best overview of this topic that I have read so far.

In The Future of Dinosaurs, Hone pointed out the frequent disparity between what people *think* we know, and what we actually know – and plenty of examples of this feature here. Some confident depictions are almost completely fictitious. The trope of the roaring T. rex leads to the question of whether dinosaurs as a group vocalised at all! This is not “overzealous scientific conservatism” (p. 159); we have found, all told, one whole fossilised voice box. The ensuing discussion on the evolution of vocalisation in birds, dinosaurs, and other reptiles shows the complexities and competing scenarios. The opposite also holds: there are topics where the general public does not realise just how much palaeontologists know, such as the anatomy of T. rex‘s face or its remarkable growth pattern with age.

The other highlight of this book is the illustrations, both the artwork and the diagrams. Witton is an accomplished palaeoartist who cares deeply about the scientific accuracy of his artwork. We thus get modern depictions of dinosaurs with fleshy lips and bulky muscles. Each of these paintings is worthy of a frame, and it is hard to pick favourites. The book’s cover, showing T. rex rumbling a closed-mouth vocalisation (a behaviour seen in modern birds and reptiles), is, in my opinion, one of the best pieces he has ever made. The azhdarchid pterosaur stalking a juvenile T. rex on page 250 is also instantly memorable. Even when the subjects are cliché, such as T. rex near erupting volcanoes or the K–Pg impactor streaking across the sky, Witton’s depictions are visually arresting. Labelled photomontages show T. rex‘s “raw osteological charisma” (p. 4), and include detailed close-ups that help you form a mental picture of what all those anatomical bits look like. Equally important are the numerous informative diagrams littered throughout the book. Witton has gone to the painstaking effort of redrawing every one of them, in the process modifying and adapting them as necessary. Instead of a mishmash of styles, ages, production values, and extraneous details, the illustrations are presented in a single unified style. It will have been a huge amount of work for something that most authors and editors would probably consider nominal gains, but it shows his attention to detail, and I, for one, rate this very highly.

King Tyrant is an instant classic: I do not even care that much for T. rex per se, but the book’s brilliant execution immediately lands it a spot in my top 5 for 2025. A compulsory buy for dinosaur enthusiasts, this book is also a valuable overview for professional palaeontologists and an inspirational example of what excellent science communication looks like.
