The papers in this book were first presented at the Association for Environmental Archaeology conference at Newcastle-upon-Tyne in 1998. The aim of the original conference was to encourage contributors to examine the inter-relationships between classes of data that have increasingly come to be treated in isolation and to encourage thinking about theory in environmental archaeology. The papers go some way to achieving these aims; some focus on explicit developments of theory, others on bridging barriers between different fields of study of classes of evidence, while others are case studies with an ecodynamic component.
