In this episode of the Nature Recovery Podcast, Stephen Thomas speaks with Professor Seirian Sumner, one of the world’s leading experts on social insects and a passionate advocate for rethinking our relationship with wasps. Seirian reveals how a reluctant PhD choice turned into a 25-year research career uncovering the remarkable societies, behaviours and ecological roles of these misunderstood insects.

Together, they explore how social evolution unfolds inside a wasp colony, why wasps are essential apex predators, and how their potential in pollination and pest control has been overlooked. Seirian explains the cultural and scientific biases that favour bees over wasps, describes global efforts to understand their ecological value, and offers simple ways to coexist with the wasps at your picnic. The conversation ranges from Malaysian rainforests to Brazilian drone-released parasitoids, and from the evolution of altruism to the future of nature recovery.

This episode will change the way you see wasps — perhaps even help you appreciate them.

Professor David Farrier (University of Edinburgh) discusses his 2025 book Nature’s Genius: Evolution’s Lessons for a Changing Planet and explores how rapid, human-driven evolutionary pressures reveal both the fragility and inventive resilience of life. We cover urban evolution (birds and snails), domestication and self-domestication, collective and distributed forms of intelligence across living systems, and how rethinking time can help us reconnect with the natural world. The conversation balances urgency with hope: we can change behaviour and systems - not by waiting for nature to “fix” things, but by learning from nature’s adaptive strategies.

Key takeaways:

• Human activities are now major selection pressures shaping evolution — sometimes rapidly.
• Plasticity (the ability of organisms to change gene expression and behaviour) offers insights for human adaptation — e.g., city design, economies, conservation strategies.
• Intelligence in nature is often collective and co-evolved; viewing ecosystems as forms of distributed intelligence could reshape politics and policy.
• Time matters: reframing our relationship with temporal scales (wild clocks vs. clock time) supports long-term thinking and reconnection.
• Nature recovery begins with “nature reconnection” — shifting how we see ourselves (embedded, not separate).

Guest bio (brief):
David Farrier is Professor of Literature and the Environment at the University of Edinburgh. His first book, Footprints: In Search of Future Fossils, examined the marks we are leaving on the planet and how they might appear in the deep-future fossil record; it was named a book of the year by both The Times and The Telegraph and has been translated into multiple languages. His new book Nature’s Genius (2025) examines how life adapts under human-caused change and what lessons that offers for our own future and has been shortlisted for major awards.

Professor Cristina Banks-Leite (Imperial College London) discusses the realities of tropical forest restoration: from large-scale reforestation projects and the practical challenges of seedlings, land tenure and finance, to why measured “success” can look counter-intuitive. She explains why current biodiversity metrics often miss the point, and how novel tools (like acoustic monitoring and AI) could transform how we listen to and protect ecosystems. A thoughtful conversation about balancing people, money and ecological intactness in nature recovery.

In this episode, Jason Williams , better known as The Cloud Gardener, shares how a lockdown balcony became a haven for biodiversity and wellbeing, leading him to the Chelsea Flower Show and a Churchill Fellowship exploring greener cities around the world.

Later, researchers Martha Crockatt and Mattia Troiano talk to Raphaella Mascia and discuss their Oxford-based work on equity of access to green space, and how social, economic and spatial inequalities shape who benefits from urban nature.

Together they reflect on what makes city greening succeed and who might be left behind.

How should we think about killing, introductions and “invasives” in a world we’ve already changed? In this episode we talk to Hugh Warwick — ecologist, writer and hedgehog champion — about his award-winning book Cull of the Wild and the uncomfortable question at its heart: can killing ever be conservation?

From hedgehogs on the Hebrides to rats on South Georgia, Hugh explores what happens when good intentions meet ecological complexity. We discuss the power of names, the moral weight of words like “pest” and “eradication,” and why conservation decisions always come with ethical consequences.

Expect humour, philosophy, and a few awkward truths — including why he thinks every scientist’s spreadsheet should have a column for cruelty.

Episode Highlights

• How the words we use — “pest,” “invasive,” “pet” — decide how animals are treated
• When eradication makes sense, and when it causes more harm than good
• The story of the Uist hedgehogs and the lessons of unintended consequences
• Why nature recovery is also people recovery — the need for social capital and empathy
• From philosophers to gamekeepers: learning from those we disagree with

This episode of the Nature Recovery Podcast discusses legal personhood of nature, also known as rights of nature or more-than-human rights. Hosts Stephen Thomas, Hannah Wilson, and Diana Gusta sit down with lawyer and professor Cesar Rodriguez-Garavito, the founding director of the More-than-Human Life (MOTH) Collective.

The discussion covers the following key points:

• The historical context of the movement: While Western legal frameworks have only recently begun adopting rights for nature, the idea is rooted in the long-standing practices and beliefs of Indigenous cultures globally.
• A groundbreaking legal moment: The 2008 Ecuadorian Constitution is highlighted as a foundational moment for the modern rights of nature movement, being the first to enshrine these rights into law. This was the result of collaboration between Indigenous leaders and a diverse group of scientists, activists, and scholars.
• Ecocentric vs. Anthropocentric views: The hosts and guest explore the difference between framing nature protection as a human right (the right to a healthy environment) versus a right inherent to nature itself (more-than-human rights). Rodriguez-Garavito argues that viewing humans as part of a larger, interconnected web of life is a more durable and effective approach, as the health of human society is directly tied to the health of the biosphere.
• Practical challenges and cultural shifts: The conversation addresses challenges to implementing these laws, such as legal costs and governmental pushback. However, it is argued that these are not new problems for social change movements, as seen in the human rights movement. The discussion concludes by highlighting the importance of cultural change and shifting perceptions, stating that legal action is just one of many tools that can be used to advance this cause.

In this illuminating episode, we tackle the increasingly tangled web of Biodiversity Net Gain (BNG) and get an update on what is happening with its current implementation. We also look at the Nature Restoration Fund — two major pieces of England’s ecological compensation puzzle.

Our guests Natalie and Matti break down what these policies are, how they affect developers, landowners, and communities — and why even good intentions may go sawry when market logic meets under-resourced local authorities.

Nature Finance – Opportunities, Challenges, and What Comes Next

In this episode, we delve into the fast-evolving world of nature finance — with a focus on schemes emerging in England, and insights relevant to the global shift toward blended finance for nature recovery. As governments increasingly look to private investment to complement public funding, what’s working, what’s not, and where is this movement headed?

We explore the key challenges facing nature finance today, from market design to policy uncertainty, and discuss promising innovations that could shape the future of investment in biodiversity and ecosystems.
