W. Carter Johnson and Dennis H. Knight have blended the natural and human histories of the Northern Great Plains into a well-illustrated, comprehensive work. Covering a vast period of time, they move from geological developments millions of years ago and the effects of glaciers to the effects of agriculture in recent centuries. The book ends with a discussion of the future of this region under conditions of climate change, with recommendations about how to balance agriculture and other pressing needs in the twenty-first century. Johnson and Knight bring decades of experience to chapters on the major ecosystems of the Dakotas. Written for readers with varying backgrounds, and with discussions of the Prairie Pothole Region, Missouri River, grasslands, woodlands, the Black Hills, and rivers and wetlands, the book is unique and will become a long-lasting source of information. Readers will appreciate the photography and other colorful illustrations.
