Mike Dilger's nationwide quest to find 1,000 wild plant species in a single year. For most of 2020, Mike Dilger's day-job of travelling to the four corners of the British Isles all but disappeared. Having been confined to one place by the Covid pandemic, and with daily dog walks his sole permitted outdoor pursuit, the simple pleasure of getting to know the flowers at his feet reignited a long-buried botanical passion. Now Mike is on a mission: to see a thousand different wild plants in one calendar year, and assess how our fascinating flora is faring in modern Britain. From Cornwall to Kent and Breckland to the Scottish Highlands, Mike meets the resilient reserve wardens and courageous conservationists tasked with protecting some of the nation's richest botanical sites, and experiences first-hand the many difficulties associated with saving our rarest and most charismatic plants. Taking in city centres, mountain tops and every conceivable habitat in between, One Thousand Shades of Green is a manifesto on how to love and conserve our green and pleasant land, and celebrates the beauty and diversity of the nation's plants.
