The Changing Mile, originally published in 1965, was a benchmark in ecological studies, demonstrating the prevalence of change in a seemingly changeless place. Photographs made throughout the Sonoran Desert region in the late 1800s and early 1900s were juxtaposed with photographs of the same locations taken many decades later. The nearly one hundred pairs of images revealed that climate has played a strong role in initiating many changes in the region. This new book updates the classic by adding recent photographs to the original pairs, providing another three decades of data and showing even more clearly the extent of change across the landscape. During these same three decades, abundant information about climatic variability, land use, and plant ecology has accumulated, making it possible to determine causes of change with more confidence. Using nearly two hundred additional triplicate sets of unpublished photographs, The Changing Mile Revisited utilizes repeat photographs selected from almost three hundred stations located in southern Arizona, in the Pinacate region of Mexico, and along the coast of the Gulf of California. Coarse photogrammetric analysis of this enlarged photographic set shows the varied response of the region's major plant species to the forces of change. The images show vegetation across the entire region at sites ranging in elevation from sea level to a mile above sea level. Some sites are truly arid, while others are located above the desert in grassland and woodland. Common names are used for most plants and animals (with Latin equivalents in endnotes) to make the book more accessible to non-technical readers. The original Changing Mile was based upon a unique set of data that allowed the authors to evaluate the extent and magnitude of vegetation change in a large geographic region. By extending the original landmark study, The Changing Mile Revisited will remain an indispensable reference for all concerned with the fragile desert environment.

Using materials drawn from a variety of disciplines, this book explores the repective parts played by man and climate in altering the face of the arid Southwest of the United States and the arid Northwest of Mexico.

Four vegetation maps of the upper Gila River valley show changes in channel width and vegetation of the past 50 years.

Offering a cross-country examination and comparison of drought awareness and experience, this book shows how scientists, water managers, and policy makers approach drought and water scarcity in arid and semi-arid regions of Spain, Mexico, Australia, South Africa and the United States.

When initially published more than twenty years ago, Thinking Like a Mountain was the first of a handful of efforts to capture the work and thought of America's most significant environmental thinker, Aldo Leopold. This new edition of Susan Flader's masterful account of Leopold's philosophical journey, including a new preface reviewing recent Leopold scholarship, makes this classic case study available again and brings much-deserved attention to the continuing influence and importance of Leopold today. Thinking Like a Mountain unfolds with Flader's close analysis of Leopold's essay of the same title, which explores issues of predation by studying the interrelationships between deer, wolves, and forests. Flader shows how his approach to wildlife management and species preservation evolved from his experiences restoring the deer population in the Southwestern United States, his study of the German system of forest and wildlife management, and his efforts to combat the overpopulation of deer in Wisconsin. His own intellectual development parallels the formation of the conservation movement, reflecting his struggle to understand the relationship between the land and its human and animal inhabitants. Drawing from the entire corpus of Leopold's works, including published and unpublished writing, correspondence, field notes, and journals, Flader places Leopold in his historical context. In addition, a biographical sketch draws on personal interviews with family, friends, and colleagues to illuminate his many roles as scientist, philosopher, citizen, policy maker, and teacher. Flader's insight and profound appreciation of the issues make Thinking Like a Mountain a standard source for readers interested in Leopold scholarship and the development of ecology and conservation in the twentieth century.

Kent Ryden does not deny that the natural landscape of New England is shaped by many centuries of human manipulation, but he also takes the view that nature is everywhere, close to home as well as in more remote wilderness, in the city and in the countryside. InLandscape with Figures he dissolves the border between culture and nature to merge ideas about nature, experiences in nature, and material alterations of nature. Ryden takes his readers from the printed page directly to the field and back again-. He often bypasses books and goes to the trees from which they are made and the landscapes they evoke, then returns with a renewed appreciation for just what an interdisciplinary, historically informed approach can bring to our understanding of the natural world. By exploring McPhee's The Pine Barrens and Ehrlich's The Solace of Open Spaces, the coastal fiction of New England, surveying and Thoreau's The Maine Woods,Maine's abandoned Cumberland and Oxford Canal, and the natural bases for New England's historical identity, Ryden demonstrates again and again that nature and history are kaleidoscopically linked.

This book explores the theory of ecogeomorphic pattern-process linkages, using case studies from Europe, Africa, Australia and North America. Sets forth a research agenda for the emerging field of ecogeomorphology in drylands land-degradation studies.
