Unearthed - The need for seeds, with Cate Blanchett
Hosted by Royal Botanic Gardens, Kew · EN
From the Royal Botanic Gardens, Kew, Unearthed returns — celebrating 25 years of the Millennium Seed Bank at Wakehurst, the most biodiverse place on our planet.
Hosted by Cate Blanchett, Kew’s ambassador for Wakehurst, this series explores the story of the world’s largest wild seed bank — a vault and living laboratory where science and conservation meet. From restoring habitats to protecting biodiversity, these seeds hold the promise of our planet’s future.
This is no distant insurance policy. It’s one we’re already relying on — and one that will only grow in importance as our climate changes and biodiversity is lost.
As the Seed Bank marks its 25th anniversary, Cate discovers how its groundbreaking work is already shaping life on Earth — and why its mission has never mattered more.

The Future: Future-proofing seeds
Nov 500:33:42Tap to summarizeIn this final episode of Unearthed: The need for seeds, Cate Blanchett looks ahead to the next 25 years of the Millennium Seed Bank – and beyond. First stop: space. Dr Anne Visscher is a Research Fellow in the seed and stress biology team. She shares her pioneering work sending seeds to the International Space Station, revealing how experiments in orbit are helping scientists understand how plants might survive extreme environments — from future planets to a changing Earth. Back on the ground, Senior Research Leader in seed biology Dr Louise Colville takes Cate into the cryogenic labs to uncover how scientists are developing new preservation techniques for seeds too fragile for conventional storage. The MSB’s mission is also growing worldwide. Megan Engelhardt, Seed Bank Manager at Missouri Botanical Garden, USA, and James Amponsah, Head of the Tree Seed Centre at Forestry Research Institute of Ghana, explain how Kew’s training and expertise are helping them to share their knowledge across the USA and Ghana. Finally, Cate reflects on what she’s learned, banking on the knowledge that something as small as a seed can provide one of the greatest solutions to our planet’s future.

The Present: Inside the world’s largest seed bank
Oct 2900:34:59Tap to summarizeThe Millennium Seed Bank holds over 2.5 billion seeds – but where do they all come from, and how do they end up in those deep underground vaults? In this episode of Unearthed: The need for seeds, Cate Blanchett joins UK Seed Conservation Coordinator Ted Chapman and UK Conservation Projects Officer Isabel Negri on a seed-collecting mission in the South of England. Searching for yellow rattle, she learns how scientists balance collecting enough for research while leaving nature undisturbed. Seeds also arrive from across the globe. Nattanit Yiamthaisong, a PhD student, shares how her research at the MSB is helping her understand how temperature affects germination — skills she’ll take back to her forest restoration work at Chiang Mai University. Back at Wakehurst, Seed Curator Sian McCabe guides Cate through the labs where seeds are dried, cleaned, and x-rayed before being sealed deep in the vaults — the beating heart of this global effort to protect plant life for generations to come.

How does nature network?
Jul 31, 202401:04:55Tap to summarizeHow do nature’s wonderful systems all fit together? And how can science help us understand these for better conservation and restoration of species? In the final episode of Unearthed: Nature needs us from the Royal Botanic Gardens, Kew, Mya-Rose Craig (AKA “Birdgirl”) takes a tour of mountain systems, weather and climate, migration, cloud forests and coastlines. Find out how Kew are learning from and mapping mysterious and delicate desert ecosystems in South America and hear about an innovative cross-community project in Colombia’s forests. Then ZSL’s Henry Hakkinen reveals some astonishing facts about migratory species Our wonderful world is a delicate balance of systems and conservation can happen at every scale – from back gardens and window boxes to landscapes hundreds of miles wide. But what needs to happen at a policy level to support and inspire the work of individuals and groups who are putting the science into action for nature? Isabel Milligan of Great Yellow is joined by Green Alliance’s Heather Plumpton and WWF’s Nitika Agarwal to ask what governments and the commercial sector must do to support biodiversity around the world.

How can we regenerate nature successfully?
Jul 17, 202400:59:58Tap to summarizeIn this episode of Unearthed: Nature needs us from the Royal Botanic Gardens, Kew we ask what it means to regenerate and restore degraded forests and landscapes, and why so many tree-planting projects in the past have failed. Mya-Rose Craig (AKA “Birdgirl”) hears from Kew’s scientists including Dr James Borrell, and Dr Kate Hardwick, who are leading the conversation and collaborating with other organisations on how to reforest and regenerate successfully. We visit the Woodland Trust’s Home Farm, one of the largest native woodland creation sites in Southern England, where Forest Research Forest Ecologist Nicola Cotterill is carrying out research into how genetic diversity can help strengthen the ecosystem. Building back ecosystems with genetic resilience is essential if we want species to survive disease, pests, climate change and other changing conditions. But UK woodlands are facing an enormous battle with Ash Dieback. We meet Russell Croft, the Arboretum Manager at Wakehurst, to find out how the team there are managing the effects of this disease in Kew’s own beautiful nature reserve. And Professor Katie Field explores how the past can unveil incredible insights into our forest ecosystems. Further afield, in Thailand, Professor Steve Elliot and the team at FORRU (Forest Research and Restoration Unit at Chiang Mai University) are working with schools to run innovative seed collection and tree planting programmes as part of their version of the “Framework Species Methodology”. As they restore tropical forest ecosystems, Steve explains how all wildlife is prospering from planting the right kinds of species in open areas close to natural forest. Kew’s partnerships around the world enable amazing seed conservation and species reintroduction work to take place and this has extended to the volcanic slopes of Indonesia, at Mount Ciremai. Dr Dian Latifah and Dr Yayan Kusuma from BRIN tell us about this exciting project. Dr Kate Hardwick has worked heavily in the tropics and is Restoration Coordinator for Kew’s Millennium Seed Bank Programme. She and Isabella Tree – Wilding author and co-owner of the Knepp Estate in Sussex – unpick the differences between rewilding and regeneration and explore the spectrum of conservation that encompasses these approaches to regenerating our landscapes.

How can we protect pollinators?
Jul 3, 202400:53:53Tap to summarizeAs well as our beloved bees, pollinators include wasps, moths, hoverflies, butterflies, beetles, bats and birds. There are about 1,500 different insect species helping plants reproduce in the UK alone, and without them our world would be less colourful, less nutritious and less diverse. In this episode of Unearthed: Nature needs us from the Royal Botanic Gardens, Kew hear how pollinator health supports the health of humans and the planet. Dr Mya-Rose Craig finds out how the biodiversity of our habitats can support pollinators against the pressures they face from climate change and human activity. Professor Phil Stevenson busts myths surrounding honeybee conservation projects whilst Professor Adam Hart looks at how we might need to change our outlooks and practises for the good of our pollinating friends. We also dive into the wonder of meadow and prairie habitats with Iain Parkinson at Wakehurst, Kew’s wild botanic garden, and with Great Yellow’s Isabel Milligan. Ever wondered how healthy your garden is for pollinators? Advolly Richmond considers how our social history has impacted the plight of plant-pollinator relationships. Then it’s into the landscape at Wakehurst with Dr Janine Griffiths-Lee and Chantelle Lindsay. Nature Unlockedis building a new bee bank here and inviting visitors to contribute to important research. In Dodoma in Tanzania, one researcher tells us how his team have been working with smallholder farmers to gain a host of benefits, including improved yields, via the growing of pollinator-friendly plants in their field margins. Finally, the bug-loving Dr Eleanor Drinkwater chats with Phil Stevenson about the important links between plants and wildlife for environmental biodiversity.

Why do we save seeds?
Jun 19, 202400:46:12Tap to summarizeSeeds are the beginnings of life. From the food we can grow today, to the wondrous habitats they can create. They offer us a chance to capture, store and even design the landscapes of the future. In this episode of Unearthed: Nature needs us from the Royal Botanic Gardens, Kew find out how scientists around the globe are working against the clock to protect species on the brink of extinction. From the Millennium Seed Bank - the world’s largest global seed bank for wild plant species - to intrepid collection trips in harsh conditions, Dr Mya-Rose Craig explores the breadth of current research about seeds. Dr Katie Field from the University of Sheffield tells us the story of how plants and fungi colonised and shaped the planet we know today. Then Joycelyn Longdon @climateincolour meets with Kew’s Charlotte Couch and The Natural History Museum’s Ben Town at Kew’s Community Allotment to discuss how everyone can benefit from biodiversity research that includes and values communities.

Why does soil matter?
Jun 5, 202400:49:17Tap to summarizeThere is still so much to learn about the mysterious realm of soil. From the microscopic organisms essential to life on Earth, to the complex and wonderful associations between plants and fungi, the ground beneath your feet is teeming with life. Dr Mya-Rose Craig explores soil in this episode of Unearthed: Nature needs us from the Royal Botanic Gardens, Kew. Find out how our world’s health is impacted by forces we may not even be able to see, and how this plays out on the scale of crop health, biodiversity in environments and the nutritional wealth of landscapes. We head to Kew’s world-class fungarium with Professor Irina Druzhinina, and into Wakehurst’s diverse woodlands where conservation research is going on to understand gas exchange between the earth, atmosphere and vegetation. Dr Gary Egan and Dr Phil Wilkes show us around this living laboratory in Sussex. Mya also hears how conservation of Madagascan grasslands, which are important carbon sinks, goes hand-in-hand with providing value to local communities through livestock grazing. And hear from Dr Feng Cai, whose research into plastic-eating fungi on China’s saltmarshes is powering innovative research into cleaning up this global pollution problem and supporting important habitats. Then it’s off to FarmED in Oxfordshire where “Rooted” author Sarah Langford meets with fellow farmers Ian Wilkinson and Andy Cato of Wildfarmed (and Clarkson’s Farm) to discuss how modern farming is transitioning to working with soil regeneration and longevity of our environments in mind. But it’s not just about changing hearts and minds, they chat about the social, economic and policy changes that are vital in supporting farmers to save our beloved landscapes.
