Trees A Crowd

A Galápagos native – born on Isla Isabela – marine biologist and conservation geneticist Diana Pazmiño focuses her research on rays, sharks, and the human communities that live alongside them. In this relaxed discussion with David Oakes, Diana explains why she brings conservation science home, how education shapes what gets noticed, valued, and protected, and what ‘protected’ actually means in practice – especially in those liminal spaces where rules and regulations require regular enforcement. Nothing epitomises Diana’s belief in the value of education more than the project she initiated on the archipelago – The Gill’s Club. Empowering girls aged 8 to 12 across the four inhabited islands of the Galápagos through experiential learning in marine science and conservation, The Gill’s Club fosters a strong bond with the ocean, develops aquatic skills, critical thinking, and female leadership. They also explore what happens when conservation becomes purely prohibitive, how bans can drive use underground, and why durable protection depends on local buy-in, education, and a sense of shared identity that’s still being built. This episode was recorded live at the Galápagos Science Centre on Isla San Cristóbal in the Galápagos. Hosted on Acast. See acast.com/privacy for more information.

In the second of two CITES-centric episodes, this episode finds David in conversation with Australian filmmaker Abraham Joffe – director of Trade Secret, the award-winning documentary exposing the global trade in polar bear skins. While climate change relentlessly erodes the sea ice these animals depend on, Abraham reveals how polar bears are still legally trophy-hunted, skinned and sold as luxury rugs and taxidermy, their fate decided in conference halls thousands of miles from the Arctic. David and Abraham explore how Trade Secret follows journalists, advocates and Arctic guides – including previous guest Iris Ho – as they investigate both legal and illegal polar bear markets, and push for the species to be “uplisted” to the highest level of CITES protection. Along the way, they discuss the blurred line between filmmaking and journalism, the ethical weight that comes with shaping a story in the edit, and the power – and limits – of a documentary to change international policy. Crucially, the conversation also turns north, to the Indigenous communities who have lived alongside polar bears for generations. Abraham reflects on the cultural and subsistence importance of traditional hunting, how little money actually reaches those communities from the luxury trade, and why giving polar bears the protection they deserve doesn’t have to mean erasing the people who share their icy home.

Recorded on the outskirts of Samarkand, Uzbekistan, this episode finds David at the 20th Conference of the Parties to CITES – the global treaty that has regulated international trade in endangered species for the past 50 years. Inside, beneath flickering lights, 185 nation-states haggle over commas, clauses and quotas; at the back of the room sit conservation NGOs, animal welfare groups, trophy-hunting lobbyists, biomedical interests and import–export industries, all vying to shape the fate of the world’s wildlife. Amid this diplomatic circus, just outside the expo centre, David sits down lakeside with Iris Ho, a proudly self-professed “CITES nerd”. Born in Taiwan and now based in Washington, DC, Iris is Head of Campaigns and Policy at the Pan-African Sanctuary Alliance (PASA) – the largest network of accredited primate sanctuaries in Africa. She explains how PASA’s work caring for rescued primates on the ground connects directly to the policies debated in those halls, and why a single well-crafted decision can protect far more animals than any one sanctuary ever could. Together, they explore Iris’s efforts to up-list the golden-bellied mangabey to the highest level of CITES protection, to re-establish an international great ape enforcement task force, and the troubling case of a private “rescue centre” in India that has imported tens of thousands of wild animals under highly questionable circumstances. Along the way, Iris reflects on growing up in a Taiwan where shark fin soup went unchallenged, the quiet shift in public attitudes she’s witnessed across Asia, and how daily walks in her local DC nature reserve give her the strength to keep fighting for the natural world. It’s an episode about primates and policy, hope and heartbreak – and about why, if we truly care for the wild lives we share this planet with, we might all need to become just a little bit more “nerdy” about treaties like CITES.

Following on from the conversation with Dr Bhaskar Choudhury in the previous episode... Recorded further south, near Bandhavgarh National Park in the Indian state of Madhya Pradesh, this bonus episode is with Amrit Menon, department head of the Wildlife Trust of India’s (WTI) Wild Aid division. This conversation looks not solely at rescue and rehabilitation, but at coexistence. What happens when wild animals are forced from their traditional habitats into states that have never before had to co-exist with them? For example, how do local farming communities adapt to life when their new neighbours are forty-five elephants strong? This conversation details the WTI’s Rapid Action Projects - RAPS — funded in part by David Shepherd Wildlife Foundation. Think of RAPS as conservation’s Thunderbirds: small, nimble teams that drop into crisis zones, offer immediate help, and try to stop future problems before they grow. We’ll then head into the field — to meet with some of the farmers facing the daily reality of elephantine visits, and the RAP project manager there on the floor, Meghna Bandyopadhyay. With thanks to David Shepherd Wildlife Foundation for making this episode possible. Hosted on Acast. See acast.com/privacy for more information.

David travels to the floodplains of Assam to meet the Wildlife Trust of India’s Dr Bhaskar Choudhury, veterinarian and project head of the Centre for Wildlife Rehabilitation and Conservation (CWRC) in the heart of Kaziranga Tiger Reserve. From one-horned rhinos and swamp deer to clouded leopards and king cobras, Kaziranga’s UNESCO-protected grasslands host a breathtaking array of life – yet each monsoon, the mighty Brahmaputra River rises, displacing animals into the paths of highways, villages, and tea estates. Dr Choudhury’s team rescues the injured, the orphaned, and the lost – from palm squirrels to Asian elephants – nursing them back to the wild in what can be a ten-year journey of care, acclimatisation, and eventual release. Together, they discuss the delicate science of wildlife rehabilitation, the changing flood patterns of a climate-altered landscape, and the deep reverence with which Assam’s people greet the elephants they call gods. Along the way, Dr Choudhury reveals the quiet triumphs and heartbreaks of rewilding India’s giants — and why, after decades of work, the moment an elephant calf rejoins a wild herd still feels like a prayer answered.

Amid the energy of the IUCN World Conservation Congress, David meets legendary marine biologist, oceanographer, and explorer Dr Sylvia A. Earle — affectionately known as “Her Deepness.” Still diving at 90, Sylvia began her career with a PhD in phycology (the study of algae) in 1966, has graced the cover of TIME magazine, authored nearly 200 scientific papers and 13 books, logged over 7,000 hours underwater, and still holds the 1979 record for the deepest solo dive — 380 meters beneath the sea. Joining her is conservation biologist Dr Tessa Hempson, Chief Scientist at Mission Blue, the nonprofit Sylvia founded in 2009. Mission Blue inspires global action to explore and protect the ocean through its network of Hope Spots — special places vital to ocean health. Partnering with local communities, scientists, and policymakers, the organization drives awareness, expeditions, and protection efforts toward one shared goal: safeguarding 30 percent of the ocean by 2030. Five years to go… Sylvia speaks of the fish she calls her friends — sentient beings with personalities, intelligence, and an inherent right to thrive in their ocean home. She reflects on the species lost to time — from the Steller’s sea cow to the dodo — their fate sealed by humanity’s destructive hand. And with a glint of curiosity, she admits her wish to meet a megalodon, that ancient giant of the deep. Yet her message is not one of nostalgia, but of hope. Sylvia believes the youth of today hold the key to a blue future — one where curiosity, courage, and compassion can restore balance to the seas she has spent a lifetime defending. Hosted on Acast.

Last Summer, MGL shared a very exciting secret with me. A year on, it is with no small amount of delight that I can now finally cease my silence! In Maya’s words: “I have written a book about Portly the Otter, son of Otter from The Wind in the Willows. It is modelled on Kenneth Grahame’s original, as a series of riverbank stories, and features characters we all know and love, as well as introducing you to some new ones. The book is called The Adventures of Portly the Otter - Untold Tales from The Wind in the Willows and will answer a mystery I wondered about a lot as a child, which is - what really happened to Portly for him to be missing for so long, and end up - discovered by Ratty and Moley,- curled up between the cloven hooves of the god Pan? The book is illustrated by the fabulous Polly Dunbar and will be printed as a four colour hardback gift book in March 2026 by Farshore. I cannot tell you what a joy it has been to revisit the riverbank and spend time with the much beloved Ratty, Moley, Badger, and of course the mischievous Mr Toad, but the biggest delight of all has been spending a year researching and learning about otters.” Hosted on Acast.

A writer concerned with wondrous beetles and beautiful birds, M G Leonard and her award-winning books, for the past decade, have been inspiring the entomologists and ornithologists of tomorrow. Here, Leonard joins Oakes on the banks of the river that inspired Kenneth Grahame's "The Wind in the Willows" for an episode about how Nature and Storytelling are vitally important in inspiring young (and old) minds. In an interview that spans the arts - everything from Shakespeare to "Starship Troopers" - David and Maya discuss why badgers walk like an actor called Michael Bryant, how Ladybirds are actually Transformers, why Entomologists hate "The Hungry Caterpillar", and why beetles deserve a co-credit for authoring Darwin's "The Origin of the Species". Most importantly, hear how Maya’s journey into our natural world was far from guaranteed; in reality, it was a wild journey forged through stories, storytelling and one or two lies. Initially just a "Bug Tourist", Maya is now the Vice President for the insect charity BugLife, and manifested the world's first Masters Degree in Entomology. All that, and how to survive if you were ever to find yourself in a battle against a human-sized beetle!

Britain and its rural communities have been obsessed with Badgers for centuries. Sometimes cast as hero, sometimes as villain, tales of their behaviour can be found woven into the fabric of our nation's folk stories. They have since been immortalised in literature by the likes of Beatrix Potter and Kenneth Grahame. Their prominence in rural life continues into our modern Britain, where Badgers find themselves in the crosshairs of an ongoing cull. But are Badgers the villain of this new tale - persecuting farmers trying to make ends meet within our complicated food chain - or are they the unfortunate scapegoat in a politically-motivated act of extreme animal cruelty? David meets up with Dr Hannah Trayford, the Badger Trust Campaigns and Research Manager, and award-winning photographer Rachel Bigsby, the Badger Trust Youth Ambassador, to understand a little more about the realities of the ongoing cull, and the (lack of) science backing it up. Is it justifiable to cull 50% of the national Badger population, when it is 800 times more likely for cattle to spread Bovine Tuberculosis to Badgers, than the other way around? And if that all sounds too dour, then fear not, for the first 20 minutes of this podcast is actually about Orang-utans and the joy of photographing sea birds!

Matthew Oates is a naturalist, nature writer, and poet with a lifelong passion for butterflies. In the short sward of the Cotswolds, Matthew takes David Oakes on a journey through his fluttery past. They discuss the writers who have inspired him, from Tolkien to Wordsworth and W.H. Hudson, and share stories of other notable butterfly enthusiasts, such as Sir Winston Churchill. Matthew explains his belief that true conservation is a blend of science and love. They also delve into the realities of developing a love for nature in the boarding schools of the Swinging Sixties - a time when his generation transitioned "from Molesworth to Jimi Hendrix in just three years," leaving little room for butterflies or a life-defining obsession with the intoxicating Purple Emperor. Their conversation also addresses modern concerns for butterfly conservation, including pathogens and parasites, the risks of unsanctioned releases, and the importance of single-species ecologists - “insects shout loudest and first.” Ultimately, this is a discussion about the metamorphoses of both the past and the future.

In the second part of David Oakes' interview with Professors Fiona Mathews and Tim Kendall, the mammal-enthused trio head into the Forest of Dean in search of Wild Boar! Fiona Mathews is a professor of Environmental Biology at the University of Sussex and the founding Chair of Mammal Conservation Europe; Tim Kendall is a professor of English Literature and Creative Writing at the University of Exeter, and; their dog Charlie Brown is an especially trained labrador with the talent for locating the bodies of bats that have been killed or injured by wind turbines, all in the name of conservation science. Together, they wrote the Wainwright award-nominated book “Black Ops & Beaver Bombing: Adventures with Britain’s Wild Mammals”. In this two part interview, hear how Fiona’s construction of the Red List for British Mammals informs our Government and has lead to cutting edge mammal conservation projects. They discuss the British Coypu population that caused concern in the 1980s, the effectiveness of the mysterious “Beaver Bombers” secretly releasing animals across Europe, and the tale of the lone Scottish Pine Marten that ended up in Georgia, USA (a fate subjectively worse than the Beech Marten who got stuck in the Large Hadron Collider!) The trio of Fiona, Tim and David (alas without Charlie Brown) then head into the Forest of Dean to locate the most contentious of Britain’s mammals – the Wild Boar!

Rob Stoneman wanted to make lots of money in the oil industry… and then he found peat! This episode is a deep dive into that blancmange-like substance that should be our saviour. Also, the Wildlife Trusts’ plans to grow a new rain forest in North Wales and Rob’s dream of having a mile deep nature reserve that circumnavigates the entirety of the British Isles coastline. A geologist at source, Rob has grown into a leading expert on the pragmatism required for landscape reform on the British Isle. Before becoming the inaugural Director of Landscape Recovery at the Wildlife Trusts, Rob managed vast areas of burgeoning biodiversity across the European continent for Rewilding Europe. Prior to that, he ran the Sheffield, then Hampshire and then the Yorkshire Wildlife Trusts. Rob and David tackle some genuinely daunting subjects: green finance and carbon credits, the feasibility and required timescale for achieving carbon neutrality, the post-Brexit opportunities for reformed agro-subsidy schemes, the potential symbiosis between nature tourism and food production, how conservation NGOs collaborate without becoming an enviro-cartel, and there’s even time to squeeze in a compliment to none other than Michael Gove(?!) And if that doesn’t float your boat, then stick around for the bison, the elk, and the pumas that prey upon guinea pigs!

The Horstmann Trust is a brand new charity primarily focused upon breeding and ultimately releasing back into the wild four species of endangered vultures: the Bearded, Egyptian and Hooded Vultures, as well as the Andean Condor. But what makes the Horstmann Trust particularly interesting, is that these birds are Welsh Vultures! In this episode, David heads to Wales to meet Holly Cale & Adam Bloch, the custodians of around 70 birds which were previously the private collection of a brilliantly eccentric Carmarthenshire-based German Hotelier called Manfred Horstmann. This is a meaty discussion. As well as dissecting the realities underpinning a successful breeding programme, it is one that explores the Vulture’s complicated relationship with Humans. From Vultures being worshipped by the Ancient Egyptians, and enabling Sky Burials in India (where our dead are not buried or cremated, rather taken, bite by bite, back into the air), to wiping out 99.9% of Southern Asian vultures though the veterinary use of anti-inflammatory drugs, or through ritualistic superstitions that require the dismemberment and smoking of Vulture brains in order to see into the future. And if that isn’t enough, this is a podcast about birds vomiting and pissing on their legs - what’s not to love?!

At the launch of his latest video installation at the Tate St Ives, artist Andy Holden meets with David Oakes to discuss the creativity present within the bird world. But, whilst exploring avian aesthetics, Andy's artwork - "A Natural History of Nest Building" - also explores the roles of nature versus nurture at an additional level. This exhibition, one exploring how and why Birds learn to create nest structures, is created by a father and son team; the son an artist, and the father a famous ornithologist. Which begs question: was this film, one about creating homes, nurturing eggs, and fledging one’s young, really just about birds? In this ornithological deep dive, Andy and Peter Holden discuss approaching a shared passion from opposite directions. You'll hear about the super-stimulus associated with the gaping beak of the infanticide-committing cuckoo, the individual spin that different birds of the same species place upon their own personal nests, and the complicated legacy of the mysterious egg-stealing Jordain Society. Andy Holden is a multi-faceted artist who has exhibited at the Tate Britain, has had music aired on BBC 6 Music, and has created everything from human-sized bower-bird bowers, to enormous knitted rocks based upon a piece of pyramid which he stole as a boy. His father, Peter Holden MBE, worked for the RSPB for almost 40 years to boost their youth engagement. He was most notably instrumental in developing their “Big Garden Birdwatch” - the UK’s first 'citizen science' project, which has been running now for 45 years, and counted around 190 million birds.

Dr David Hetherington is an expert on the Eurasian Lynx and the beneficial links Lynx (Lynx lynx lynx) can manifest within our complicated British ecosystems. What he doesn’t know about the Lynx’s rich history across Europe is not worth knowing: Hear why Hildegard von Bingen thought drinking Lynx urine was highly beneficial; when exactly(ish) Lynx were wiped from British shores leaving only one town name with any form of association to a once indigenous species, and; how the Nazis could be considered the twentieth century’s first big-mammal “re-wilders”. But, most importantly, David answers the big question: does Britain have enough well connected forest habitat to safely support a large mobile forest-dependent species? Specialising in species reintroduction programmes, David managed the Cairngorms Wildcat Project and actively encouraged a positive relationship with gamekeepers to help all parties work for nature conservation without getting “sucked into the vortex of raptor politics”. He also sits on the board of Trees for Life - an award-winning charity that works to enhance the native woodland ecology of the Scottish Highlands. To that end, expect wildcats, red squirrels, pine martens, capercaillies, as well as the animal so cool they named it thrice, Lynx lynx lynx, in this immersive and informative wildlife deep dive.

Dr Ruth Tingay is a conservationist and campaigner who has spent her career primarily focused upon the world’s raptor population (that’s Birds of Prey, rather than Veloci-...) Her career was inadvertently kickstarted through working at Heathrow airport’s Animal Reception Centre. Here she welcomed back the UK’s Red Kite population for their reintroduction to our country, as well as the usual pampered felines, escaped pooches, and boxes stuffed full of mystery birds. Throw Nile Crocodiles, an annual Mexican Hawk Migration of 4.6 million birds and the DNA of Golden Eagles into the mix, and you get an incredibly varied career that has leapfrogged the globe from Mauritius to Mexico then on to Madagascar and many other countries beginning with ‘M’ besides. But since 2009, Ruth has been focused upon the plights of our domestic birds; shedding light upon wildlife crime through her Raptor Persecution blog, and through joining with Mark Avery and Chris Packham to spearhead their Wild Justice which is holding the Governments of Britain to account for ongoing enviro-failings and eco-crimes.

Hello, and welcome to a little festive bonus Trees A Crowd. Some of the eagle eared amongst you may have noticed that the regular “three final questions” were missing from this month’s interview with the artist and activist, Katie Holten. Well… …it’s because they’re here! So, before I hand you over to Katie for an additional stocking filler, I wish you all a glorious Christmas, and a new year tingling with positivity and promise. Merry Christmas! Why not become a "Subscription Squirrel" on our Patreon, and help support the production of this podcast? Hosted on Acast. See acast.com/privacy for more information.

Katie Holten is a visual artist and environmental activist who splits her time between Ireland and New York. She has exhibited at the Venice biennale and many galleries across the globe, with her work being described as “…an ongoing investigation of the inextricable relationship between man and the natural world in the age of the Anthropocene.” Recently she created the internationally best-selling book, “The Language of Trees”. Reclining in a mossy moot deep within the Woodland Trust’s Duncliffe Woods, Katie shares with David Oakes how her passion for nature stems from two roots: her mother – a gardener, teacher and floral artist – and her father – a man who led Katie to be enthralled by logic and physics and Feynman. Katie is now an artist who prides herself upon collecting the connected and noticing that from chaos sprouts equilibrium. It is perhaps not unsurprising then that she has devoted her artistic career to creating compendiums of things she feel necessary to share, and devoting her personal life to many of the goals of Extinction Rebellion.
