Exploring the relationship between Native Americans and the natural world, Biodiversity and Native America questions the widespread view that indigenous peoples had minimal ecological impact in North America. Introducing a variety of perspectives - ethnopharmacological, ethnographic, archaeological, and biological - this volume shows that Native Americans were active managers of natural ecological systems. The book covers groups from the sophisticated agriculturalists of the Mississippi River drainage region to the low-density hunter-gatherers of arid western North America.This book allows readers to develop accurate restoration, management, and conservation models through a thorough knowledge of native peoples' ecological history and dynamics. It also illustrates how indigenous peoples affected environmental patterns and processes, improving crop diversity and agricultural patterns.
