Why are red deer populations in Germany growing in number and antler size yet sitting in deep genetic trouble? What is the difference between census population size and effective population size, and why does it matter? And how can a satirical award for the worst-built wildlife crossing draw attention to the issue of habitat fragmentation? In this episode, I sit down with Frank Zabel, a wildlife biologist, campaigner, and co-host of the award-winning JAGDcast podcast. Frank also runs the nonprofit RotWildes Deutschland (Non-profit Society for Wildlife Biology & Sustainable Use) and authored the 2022 deer management plan focused on corridors and mapping. Although Frank is speaking from Germany, many of the issues he raises will feel familiar to anyone interested in deer management, habitat connectivity, and how policy decisions made decades ago continue to shape what happens on the ground today.Frank takes a broader view of red deer as an umbrella species, using them as a vehicle to talk about biodiversity in general. We discuss the historic genetic bottleneck created when red deer were extirpated in much of Germany after the 1848 revolution and how that legacy still shapes populations today. Frank explains why most German red deer populations now sit dangerously close to or below the threshold where the issues with inbreeding start to appear, even though the absolute numbers look healthy on paper. Our conversation also covers the red deer management areas in southern Germany, where deer must be shot once they leave designated zones, a policy decision rooted in post-war food production priorities that has become, in Frank’s words, a far more effective form of habitat fragmentation than any motorway.We then shift gears to the lowering of the wolf’s protection status in the EU. Frank offers a perspective that may surprise some listeners, particularly those who expect hunters to take a predictable line on the wolf question. He also makes a compelling case for why looking at wolves across the whole of Europe through a single lens misses what is actually happening on the ground in different regions. We touch on what hunters need to do when wolves return to an area, and Frank shares an observation from his time in Sweden that illustrates the point well. This is a rich conversation packed with wisdom and insight.Subscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Follow Tommy's Outdoors on Bluesky, Instagram or YouTube

What if the world's most powerful climate solution is being logged away while politicians and industry groups feed us misinformation? How can an ecosystem store three times more carbon per acre than the Amazon rainforest? Why has the international science community remained largely silent about the destruction of temperate rainforests? Our conversation with Paul Koberstein, co-author of "Canopy of Titans - The Life and Times of the Great North American Temperate Rainforest" tackles these urgent questions head-on. The Great North American temperate rainforest stretches 2,500 miles from northern California to Alaska, making it the largest intact temperate rainforest on Earth. Yet this carbon-dense ecosystem faces ongoing threats from industrial logging, greenwashing campaigns, and policy decisions that prioritise short-term profits over long-term climate stability.Paul shares his journey from camping beneath old-growth Douglas firs as a child to becoming an investigative environmental journalist covering forest issues for over 40 years. Our conversation examines the troubling parallels between the timber industry's tactics and those employed by fossil fuel and tobacco companies. We discuss how scientists like Dr Beverly Law faced persecution for publishing research on how forests benefit the climate. Paul explains the "global blind spot" that has allowed temperate rainforest logging to continue largely unchallenged, even as the international community rallies to protect tropical rainforests. The book reveals how industry-funded research has shaped policy debates and obscured the true climate impact of logging these ancient forests.Despite the sobering realities, Paul offers hope through examples of successful grassroots activism. When thousands of people raised their voices against Drax's expansion into California, the project was cancelled. Our conversation also touches on the dramatic shift in US climate policy under different administrations and what this means for forest protection efforts globally. Paul's advice is clear: to save a forest, you must work at it every day, but to destroy it, you only need to do it once. This episode is essential listening for anyone who cares about climate action, forest conservation, and cutting through corporate greenwashing.Subscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Follow Tommy's Outdoors on Bluesky, Instagram or YouTubeTommy’s Outdoors is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.co.uk The guest featured in this episode paid a nominal guesting fee.

On my podcast, we talk a lot about coexistence with large carnivores and the challenges it poses. Some of those challenges might seem insurmountable to some. To shed some light on overcoming these hurdles, I contacted Helen Arusoo, an Estonian nature journalist and the leader of the National Animal Working Group. In this conversation, we talk about how Estonia overcame these hurdles and created something that I would consider the gold standard of coexistence with large carnivores.Unsurprisingly, the majority of our time was spent discussing wolves as they seem to be the most difficult carnivore species to coexist with, at least in the northern hemisphere. However, we did discuss other large carnivores like bears too. Our conversation focused mostly on social and cultural factors. We also touched on the European Commission's proposal to lower the protection status of wolves, something we’ve discussed extensively in one of the previous episodes.It was a wonderful conversation and I enjoyed speaking with Helen. Her profound understanding of the challenges of coexistence is impressive. She presented a deeply thought-out perspective and I can only wish that more people who care about wolves could learn from her experience and the Estonian model of coexistence with large carnivores.Subscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Follow Tommy's Outdoors on Bluesky, Instagram or YouTubeMentioned in this episode:This is the Conservation and Science podcast Replay series, a curated collection of best episodes from last year.

What is sustainable agriculture? Does regenerative farming mean focusing primarily on the soil biome? Is farming a leading cause of biodiversity loss? …and do we really have only 60 harvests left? To get the answers to those and other questions about farming and biodiversity, join me for a conversation with an agricultural management and policy specialist, an economist, a writer and an advisor, Stuart Meikle.In this episode, Stuart shares with us the history of his education in farming and later his work in different farming environments across the world. Then we switch gears and talk about issues specific to Irish agriculture, which also has some relevance in the UK context. And so, we discuss the use of nitrogen fertilisers, soil health and whether the cuts to the size of the national cattle herd are inevitable. I also ask Stuart about his thoughts on the recently passed Nature Restoration Law.After you listen to this episode, don’t forget to subscribe to my newsletter so as not to miss more farming episodes that are due in the coming weeks.

Is the resumption of commercial whaling inevitable? What hidden geopolitical forces are shaping international whale conservation efforts? Let's dive (pun not intended) into the complex world of whale conservation with marine scientist Dr Peter Corkeron. In our conversation, Peter uncovers the surprising connections between military bases, national security, and the fate of the world's largest mammals.From the history of industrial whaling to the current state of whale populations, our guest provides a comprehensive overview of the challenges facing whale conservation today. He explains how some whale species are making an impressive comeback while others teeter on the brink of extinction. But the real story goes beyond biology! Learn how US military interests in Japan may be influencing whaling policies, and why anti-whaling efforts that seemed successful for decades may now be faltering.As commercial whaling threatens to resume, we argue for a new approach to whale protection. We discuss the limitations of current conservation strategies, the complex motivations behind pro-whaling interests and why simply allowing whaling to "fizzle out" is no longer a viable option. Finally, Peter offers his perspective on potential solutions, addressing underlying geopolitical factors and advocating for policy changes to protect whale populations more effectively.Further reading:Losing the Whales: How the Anti-Whaling Narrative Has FailedThe Return of WhalingWhat US Militarism Has to Do With Japan's Quest to Slaughter More WhalesSubscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Follow Tommy's Outdoors on Bluesky, Instagram or YouTubeMentioned in this episode:This is the Conservation and Science podcast Replay series, a curated collection of best episodes from last year.

Is rewilding truly mainstream now, or does it remain mired in misunderstanding? Can we finally agree on what the term actually means? And is it really an anti-rural movement that seeks to empty the countryside of people? These questions have dominated conservation debates for years, and our conversation today tackles them head-on with refreshing clarity. Our guest is Dr Steve Carver, Director of the Wildland Research Institute at the School of Geography, University of Leeds, and Professor of Rewilding and Wilderness Science.In our conversation we explore how rewilding differs fundamentally from traditional conservation and regenerative farming. We examine the crucial role of scale, the problematic nature of fences in rewilding projects, and why the Oostvaardersplassen experiment in the Netherlands offers important lessons. Steve introduces his concept of 'nature-led versus human-led' approaches and explains why giving nature the space and time to determine its own trajectory remains the core principle. We also discuss the controversial question of whether projects like Knepp Estate truly qualify as rewilding or represent something else entirely.Throughout our discussion, Steve emphasises that rewilding is deeply context-specific and requires genuine local community engagement to succeed. He unpacks the relationship between wilderness and rewilding, explores why species reintroductions aren't mandatory, and shares his measured optimism about lynx returning to the UK (though wolves remain a more distant prospect). We also examine how the European interpretation of rewilding has evolved differently from its North American origins, and what this means for future conservation efforts. This episode offers a balanced, scientifically grounded perspective on where rewilding stands today and where it might be heading.Further reading:Guiding principles for rewildingSubscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Follow Tommy's Outdoors on Bluesky, Instagram or YouTubeMentioned in this episode:This is the Conservation and Science podcast Replay series, a curated collection of best episodes from last year.

What exactly is rewilding? Does it simply mean bringing back wolves, lynx and bears, or is there more to it? Can we balance food production and rural community needs with land left to natural processes and wildlife conservation? To answer these questions, I talk with Ian Parsons, editor of "Great Misconceptions: Rewilding Myths and Misunderstandings", a new book that explores common assumptions and misconceptions about rewilding.In our discussion, we address aspects of rewilding that are often misunderstood or misinterpreted, sometimes innocently and at other times deliberately or even maliciously. We explore three topics commonly associated with rewilding that often spark heated debate: species reintroductions, community engagement, and the choice between tree planting and natural regeneration. This discussion draws on the collective wisdom of renowned authors who contributed distinct chapters to the book.In the end, Ian emphasises that rewilding shouldn't remain just another niche concept but needs to be integrated into how we live our lives, from urban planning to politics or even business practices. He challenges the notion that rewilding is anti-rural, arguing instead that it can revitalise rural economies and provide new opportunities for communities. The episode provides valuable insights for anyone interested in conservation, land management and the future of our relationship with nature.Buy Great Misconceptions: Rewilding Myths and MisunderstandingsSubscribe to Tommy's Outdoors: Conservation and Science NewsletterSupport the Podcast and Buy Me a Coffee.Follow Tommy's Outdoors on Bluesky, Instagram or YouTubeTommy’s Outdoors is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.co.uk Mentioned in this episode:This is the Conservation and Science podcast Replay series, a curated collection of best episodes from last year.

Sika (cervus nippon) is a mid-sized deer that was introduced to Ireland in the 1860s to the Powerscourt Estate. Soon after that, it started spreading across Ireland. Today, the main concentrations of sika are in Kerry, Wicklow, Tyrone and Fermanagh. More recently, it has also been found in Waterford, Galway, Limerick, and Wexford. The National Biodiversity Data Centre in Ireland lists sika as an invasive species. Despite that, it’s afforded protection under the Wildlife Act. It is prized by hunters as a game species and a source of excellent quality venison on the one hand, and hated by foresters and environmentalists for the damage to forestry and biodiversity on the other.Sika is present on the entire European continent and, although not as widespread as in Ireland, it is also causing similar problems. This is reflected in the recent move by the European Commission to launch consultations to put sika on the Invasive Alien Species (IAS) list across the Union. This poses the obvious question: what does it mean for the Irish population of sika if the EC makes such a decision? Will or should it be allowed continuous protection with open and closed hunting seasons? Or should it be reduced to the status of vermin and be eradicated across the country? To discuss the potential future of sika deer in Ireland and present a whole spectrum of views about this species, and invasive species more generally, I spoke with four expert guests presenting different views on the subject. By listening to this episode you will hear from Professor Jaimie T.A. Dick who specialises in Invasion Ecology, Eoghan Daltun an award-winning author who has spent last 15 years regenerating an Irish Atlantic rainforest, Damien Hannigan a Government Appointee to the Irish Deer Management Forum and Public Relations Officer at the Irish Deer Commission, and Professor of Wildlife Restoration Ecology, Adam T.
