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 Using nearly two hundred additional triplicate sets of unpublished photographs, The Changing Mile Revisited utilizes repeat photographs selected from almost three hundred stations located in southern Arizona, in the Pinacate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.

Over the past century, humans have molded the Colorado River to serve their own needs, resulting in significant impacts to the river and its ecosystems. Today, many scientists, public officials, and citizens hope to restore some of the lost resources in portions of the river and its surrounding lands. Environmental restoration on the scale of the Colorado River basin is immensely challenging; in addition to an almost overwhelming array of technical difficulties, it is fraught with perplexing questions about the appropriate goals of restoration and the extent to which environmental restoration must be balanced against environmental changes designed to promote and sustain human economic development. Restoring Colorado River Ecosystems explores the many questions and challenges surrounding the issue of large-scale restoration of the Colorado River basin, and of large-scale restoration in general. Robert W. Adler evaluates the relationships among the laws, policies, and institutions governing use and management of the Colorado River for human benefit and those designed to protect and restore the river and its environment. He examines and critiques the often challenging interactions among law, science, economics, and politics within which restoration efforts must operate. Ultimately, he suggests that a broad concept of “restoration” is needed to navigate those uncertain waters, and to strike an appropriate balance between human and environmental needs. While the book is primarily about restoration of Colorado River ecosystems, it is also about uncertainty, conflict, competing values, and the nature, pace, and implications of environmental change. It is about our place in the natural environment, and whether there are limits to that presence we ought to respect. And it is about our responsibility to the ecosystems we live in and use.

Restoring the Pitchfork Ranch tells the story of a decades-long habitat restoration project in southwestern New Mexico. Rancher-owner A.

Botanist Homer L. Shantz took photographs of the Kenyan landscape in the early 1920s as part of his effort to document the natural plant cover of Africa. He returned there with B. L. Turner in the late 1950s to repeat the photographs. In 1990, Raymond Turner traveled to Kenya under the auspices of the National Geographic Society in order to match the photographs made by Shantz and B.L. Turner and to show the changes that have occurred over the decades since Shantz's initial journey. Turner's comparative photos and research into the botanical record dramatically reflect the encroachment of woody plants in arid areas and the increasing human impact in more humid locales. Turner's discussions of the photographs and the conclusions he draws provide an important reference for ecologists, geographers, botanists, and other researchers attempting similar studies. By documenting vegetation change in a region broadly similar climatically to North America's subtropical deserts and grasslands but different in its wildlife and its human culture, the book shows that the endpoints of landscape status are similar despite the vastly different histories of these two regions of the world.
