Landscapes of the Northern Great Plains have been constantly changing, but never so rapidly as under modern conditions of economic affluence and technological development. This change is multifaceted and has an impact not only on the fabric of culture and its perception of landscape, but also on the ecology and physical landforms. Multidisciplinary research has therefore become an important tool in identifying the influences that human activities have, not only on cultural landscapes but on biophysical ones as well. This collection of articles, originating in a conference held at the Royal Saskatchewan Museum in April 2000, focuses on just such an integration of research concerning the Great Plains of North America and involving the disciplines of geology, archaeology, biology, geography, sociology, and agriculture.
