Book excerpt: This book is based on a major conference with Historic England, Natural England, the Ancient Tree Forum and others which took place in 2016 as part of the celebrations for the tercentenary of Lancelot 'Capability' Brown. The event brought together ecologists, landscape historians and archaeologists, land managers and conservationists to look critically at the impact of Brown and his successors on the UK's landscape. The book addresses the paradigms of these designed landscapes. It considers the issues around the legacy of Brown's creations and ideas and the repercussions that are still apparent today. It makes for a thought-provoking and rich discussion covering habitat conservation and creation, drainage and the release of alien species. This is the untold story of the ecology of Capability Brown and the landscape school which followed.
