This study of the relationship between human activity and environmental change from the Iron Age to the end of the Anglo-Saxon period brings together the results of the latest research in many fields to reconstruct changes in climate, sea level, soils and vegetation. The consequences of the major cultural changes of the first millennium are examined, including the Roman Conquest, the end of Roman Britain, and the Anglo-Saxon settlement, revealing the different ways in which human activity modified the environment.Fully illustrated with photographs, maps and line drawings, the book will be of particular relevance to anyone with an interest in archaeology, history, geography, palaeoecology, botany, or environmental science.
