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.

The development of water and other natural resources in the Upper Colorado River Basin will continue to have an impact on the ecology of this unique ecosystem. Numerous water-development projects have been completed on the river, others are in progress, and still others are contemplated, to provide water necessary for municipalities, irrigated agriculture, and energy production. Although much information is already available on this river, it is widely scattered in the published literature and unpublished reports of various state and federal agencies. This annotated bibliography contains 1,109 published or readily available unpublished references that should be useful in decisions regarding effective management of the Upper Colorado River Basin. Selected key words were assigned to all references and indexed for ease of locating references on particular subjects.

“Mann’s book is timely, and its central theme, the role of legal, political, and scientific institutions in the utilization of water in Arizona, is appropriate. It is appropriate, moreover, for the greater region of California and the Southwest, where exist similar problems. . . . The Politics of Water in Arizona ranks along with Richard Cooley’s prize winning Politics and Conservation: The Decline of the Alaska Salmon as an outstanding contribution of a political science to the field of conservation and resource utilization.”—California Historical Society Quarterly
