Derek Ratcliffe was arguably the most outstanding field biologist and conservationist of the 20th century. This book explores the breadth, quality and legacy of Derek’s work and has many personal reminiscences. The 30 contributors provide fascinating insights to a remarkable person, and events and issues which have shaped wild nature as we see it today. Each part ends with an article written by Derek.

Derek was passionate about nature and used his huge knowledge of nature to good effect. He possessed an intense curiosity which drove him to understand and protect nature. His interests ranged from birds, butterflies and dragonflies, and mountain flora and vegetation to the ecology and biogeography of peatlands and of mosses, liverworts, and ferns. He documented birds, plants, and insects in their habitats and maintained long-term population studies on several birds of prey as well as Raven, Golden Plover, Greenshank, and Dotterel. He documented the decline of the Peregrine Falcon and famously established the role of pesticides as its cause. He led the fight that saved the wild and remote Flow Country of northern Scotland from extensive afforestation. As the Nature Conservancy's Chief Scientist, he masterminded A Nature Conservation Review, which still underpins so much conservation policy and practice in Britain. His books have become classics of natural history writing. Through his employment as a conservationist and his books and articles, he massively influenced our awareness of nature – and its vulnerability.

Beautifully illustrated, this is a deeply inspiring book. It will appeal to a wide readership, curious about what makes such a towering figure so special, and united by an eagerness to see wildlife flourish.
