Book Description
This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Book Description
"In this magnificent book, Oliver Schuchard provides more than sixty-five exquisite black-and-white photographs spanning his thirty-eight years of photography. In addition, he explains the aesthetic rationale and techniques he used in order to produce these photographs, emphasizing the profound differences between, yet necessary interdependence of, craft and content. Although Schuchard believes that craft is important, he maintains that the idea behind the photograph and the emotional content of the image are equally vital and are, in fact, functions of one another. The author also shares components of his life experience that he believes helped shape his development as an artist and a teacher. He chose the splendid photographs included in this book from among nearly 5,000 negatives that had been exposed all over the world, from Missouri to Maine, California, Alaska, Colorado, France, Newfoundland, and Hawaii, among many other locations. Approximately 250 negatives survived the initial review, and each of those was printed before a final decision was made on which photographs were to be featured in the book. The final choices are representative of Schuchard's work and serve to substantiate his belief that craft, concept, and self must be fully understood and carefully melded for a good photograph to occur. This amazing work by award-winning photographer Oliver Schuchard will be treasured by professional and amateur photographers alike, as well as by anyone who simply enjoys superb photography."--Publishers website.
