Jake Fiennes is on a mission to change the face of the English countryside. As Conservation Manager at Holkham in Norfolk, one of the country's largest historic country estates, his radical habitat restoration and agricultural work has nurtured its species and risen its crop yields - bringing back wetlands, hedgerows, birds and butterflies over 25,000 acres of land. But this isn't rewilding - there is no 'wild' in Britain anymore. Mass farming, crop science and industrial chemicals have destroyed the majority of our natural landscape and wildlife over the last century. 'Land Healer' is the story of Fiennes's ambition to bring back our flora and fauna - by reclaiming our traditions and trialling new experiments which could restore our symbiosis with our land, and save our shared future.
