ZSL Wild Science Podcast

Do you know where the wood in your floorboards comes from? Or your desk, or dining chairs? In this episode, we dig deep into the grain of a global issue that is often hidden in plain sight in our offices, our houses and our cities – tracing timber back to its source.
Harriet talks to Annabelle Dodson, ZSL's Sustainable Business Project Manager, and Victor Deklerck, Director of Science at World Forest ID, about how scientists use isotopes to pinpoint where the trees behind our wood products were grown, the role of digital tracking systems in supply chains, and real-world cases where traceability has driven more responsible sourcing and enforcement. This project is funded by Fondation Lombard Odier and the EU through the ECO-SOLVE project.
This episode is part of a series showcasing ZSL's Sustainable Business and Finance work.
Please note that this podcast was recorded before the European Commission confirmed changes to the implementation timeline of the EU Deforestation Regulation (EUDR). Compliance requirements for micro and small enterprises have been delayed to 30 December 2026 (previously June 2026), while medium and large enterprises must still comply by 30 December 2025.

What do car tyres, yoga mats and trainers have in common? They all contain natural rubber, tapped from trees by millions of small farmers, mostly in Asia. While natural rubber production is renewable, its impact on the environment through deforestation, habitat loss and soil degradation, can be great when not managed sustainably.
In this episode, we hear from a Thai rubber farmer, about the challenges faced on the ground, as well as one of the world's biggest tyre makers, Michelin, about rubber's colonial history, its tangled supply chains, and how they're working with farmers on sustainability. Finally, we explore how investors can use their influence to demand better practices and drive industry-wide change that benefits both people and nature.
This episode is part of a series showcasing ZSL's Sustainable Business and Finance work.

The coastal waters of Wales are home to a whopping 27 species of sharks, skates and rays, known collectively as elasmobranchs, and they are a fundamental part of Wales' natural heritage. But even so, research on their biology and conservation status is lacking. In this episode, Wild Science hits the road to join scientists from Project SIARC and the Ocean Predator Lab in North Wales as they work with local fishing communities to monitor tope sharks, and contribute to better understanding and conservation of shark species in the region.

Making sure that the animals held in ZSL's two conservation zoos, London and Whipsnade, are fed a diet that can help them thrive is crucial, both for keeping them healthy under managed care, and ensuring they are in the best possible shape for a return to the wild. Amanda Ferguson is ZSL's Diet Management Officer and is responsible for creating tailored diets for all the animals across both ZSL Zoos, from snails to elephants! We learn how to feed an animal for which there are no guidelines, why enriched feeding methods are so important, and why you'll rarely see a monkey at London Zoo with a banana.
