Why does soil matter?

How 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.

In 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.

As 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.

There 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.

Nature needs us! In series 3 of Unearthed, Dr Mya-Rose Craig begins the journey into what biodiversity loss means and why it matters to protect what we have left. We find out what might happen if we continue to ignore the impacts of climate change and habitat destruction in terms of its impacts on our lives, along with future life on the planet. We also explore how human action has brought us to the current dual crises of biodiversity loss and climate change. But there is still plenty of hope that we can slow down or halt these destructive processes thanks to scientific research and action across different levels of society. Kew’s Steven Bachman shares insights into the technology helping us map and prioritise conservation research and work across the planet and Dr Isabel Larridon explains how data from Kew’s State of the World’s Plants and Fungi report is the wake-up call we need. We hear from participants in the Global Biodiversity Standard: the world’s first international certification recognising and promoting the protection, restoration and enhancement of biodiversity. And we travel to Brazil’s Atlantic Forest, one of the world’s most biodiverse regions, to follow researches on a ‘bioblitz’ to identify species. Then Sonia Dhanda explains how ‘wildlife trade policy’ is an important part of balancing how we utilise and conserve species around the world and across borders. Dominique Palmer is joined by guests Sophie Pavelle and Camila Duarte Ritter to discuss what it means to ‘act now’ and why a combined effort from governments to scientists, community organisations and individuals is necessary to create positive, systemic change for nature.
