Trees A Crowd

Following on from two episodes recorded on San Cristóbal Island, this episode finds David having set sail across the Galapagos archipelago for Santa Cruz; destination: the headquarters of the Charles Darwin Foundation — the research institution founded alongside the Galápagos National Park, and still at the heart of how science becomes conservation on the islands.

Joining David is Rakan Zahawi, CDF’s relatively new Chief Executive. Rakan is a botanist and restoration ecologist who arrived after running botanical gardens in Hawaii and Costa Rica, and now helps steer one of the most ambitious ecological recovery efforts anywhere on the planet. At the centre of this conversation is the Floreana Project: a multi-decade initiative to restore the Galapagos island of Floreana to a natural state, one pre-dating humankind’s arrival in the Galapagos. By tackling invasive species at scale and rebuilding ecosystem function from the ground up, Rakan explains why removing cats and rodents is only the start, and how quickly native wildlife can rebound when pressure lifts — from finches and reptiles to the startling reappearance of the Galápagos Rail for the first time since Darwin’s 1835 visit. With that groundwork laid, attention turns to what comes next: a carefully sequenced programme of reintroductions, led by the recent (last week, no less!) return of giant tortoises to Floreana — hybrids, standing in for a lineage wiped out long ago — as a headline step in a restoration story decades in the making. All that, plus the methodical science behind biocontrol, the worries of a parasitic “avian vampire fly” that threatens Galápagos avian life, and what lies ahead for CDF and its present and future partnerships.

This episode finds David in conversation with the Galápagos-born geographer, Director of Universidad San Francisco de Quito’s Galápagos campus and Co-Director of the Galápagos Science Centre, Professor Carlos F. Mena (recorded with a chorus of barking sea lions providing an unmistakably local backdrop!)

From a NASA fellowship and early work modelling human behaviour in the Amazon, Carlos explains how his research led to a simple, uncomfortable truth: conservation succeeds or fails at the level of families. In places where survival is precarious, the forest becomes a bank account — and any environmental message that ignores poverty, health and education is doomed to stay theoretical.

From there, the conversation moves to the Galápagos as a living, inhabited system: a place of extraordinary protection and extraordinary pressure. Carlos describes the islands’ dependence on tourism, the “fortress conservation” model that tightly regulates both people and nature, and the political push to open the archipelago to outside investment. They explore how the Science Centre builds trust with local communities after a history of extractive science, why co-authorship and two-way learning matter, and how citizen-science livelihoods emerged in the shock of COVID.

The episode ends where it began — with sea lions spilling into town — as Carlos unpacks the new sea lion management plan, the challenge of educating residents and tourists alike, and the looming threat of disease in small, irreplaceable populations.

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.

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.
