Plant palaeoecologists use data from plant fossils and plant subfossils to reconstruct ecosystems of the past. This book deals with the study of subfossil plant material retrieved from archaeological excavations and cores dated to the Late Glacial and Holocene. One of the main objectives of this book is to describe the processes that underlie the formation of the archaeobotanical archive and the ultimate composition of the archaeobotanical records, being the data that are sampled and identified from this immense archive. Our understanding of these processes benefits from a knowledge of plant ecology and traditional agricultural practices and food processing. This handbook summarizes the basic ecological principles that relate to the reconstruction of former vegetations and of agricultural practices in particular. We hope this book will help palaeobotanists, environmental archaeologists, and colleagues from related disciplines optimize inferences based on what we could term old-style ar
