Available in PDF, EPUB and Kindle. Book excerpt: The Colorado River had one of the most unique fish communities in the world. Seventy-five percent of those species were found nowhere else in the world. Settlement of the lower basin brought dramatic change to both the river and its native fish. Those changes began more than 120 years ago as settlers began stocking nonnative fishes. By 1930, nonnative fish had spread throughout the lower basin and replaced native communities. All resemblance of historic river conditions faded with the construction of Hoover Dam in 1935 and other large water development projects. Today, few remember what the Colorado River was really like. Seven of the nine mainstream fishes are now Federally-protected as endangered. Federal and state agencies are attempting to recover these fish. However, progress has been frustrated due to the severity of human impact. This report represents testimony, old descriptions, and photographs describing the changes that have taken place in hopes that it will provide managers, biologists, and the interested public a better appreciation of the environment that shaped these unique fish.

Download or read book An Entirely Synthetic Fish written by Anders Halverson and published by Yale University Press. This book was released on 2010-03-02 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anders Halverson provides an exhaustively researched and grippingly rendered account of the rainbow trout and why it has become the most commonly stocked and controversial freshwater fish in the United States. Discovered in the remote waters of northern California, rainbow trout have been artificially propagated and distributed for more than 130 years by government officials eager to present Americans with an opportunity to get back to nature by going fishing. Proudly dubbed an entirely synthetic fish by fisheries managers, the rainbow trout has been introduced into every state and province in the United States and Canada and to every continent except Antarctica, often with devastating effects on the native fauna. Halverson examines the paradoxes and reveals a range of characters, from nineteenth-century boosters who believed rainbows could be the saviors of democracy to twenty-first-century biologists who now seek to eradicate them from waters around the globe. Ultimately, the story of the rainbow trout is the story of our relationship with the natural world--how it has changed and how it startlingly has not.
Download or read book River Flowing From The Sunrise written by James M Aton and published by University Press of Colorado. This book was released on 2000-12-01 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors recount twelve millennia of history along the lower San Juan River, much of it the story of mostly unsuccessful human attempts to make a living from the river's arid and fickle environment. From the Anasazi to government dam builders, from Navajo to Mormon herders and farmers, from scientific explorers to busted miners, the San Juan has attracted more attention and fueled more hopes than such a remote, unpromising, and muddy stream would seem to merit.
Download or read book Searching for Paradise written by Douglas E. Booth and published by Rowman & Littlefield. This book was released on 2002 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The signs of economic change loom large in the mountain West as shuttered mines and lumber mills are overshadowed by luxurious homes sprouting on valley bottoms and ridge lines. This perceptive book explains these changes, assesses their effects on the natural environment, and gauges the reactions of local communities. Drawing on concepts from economics, environmental ethics, and conservation biology, Booth suggests that the ultimate solution lies in re-directing population growth away from rural areas to reinvigorated and environmentally attractive ecological cities and to increase the density of development within rural areas themselves. Policymakers, activists, and local citizens concerned with rural sprawl will find this book an invaluable resource. Visit our website for sample chapters!
Download or read book Centuries of Decline during the Hohokam Classic Period at Pueblo Grande written by David R. Abbott and published by University of Arizona Press. This book was released on 2016-12-01 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the prehispanic Southwest, Pueblo Grande was the site of the largest platform mound in the Phoenix basin and the most politically prominent village in the region. It has long been held to represent the apex of Hohokam culture that designates the Classic period. New data from major excavations in Phoenix, however, suggest that little was "classic" about the Classic period at Pueblo Grande. These findings challenge views of Hohokam society that prevailed for most of the twentieth century, suggesting that for Pueblo Grande it was a time of decline rather than prosperity, a time marked by overpopulation, environmental degradation, resource shortage, poor health, and social disintegration. During this period, the Hohokam in the lower Salt River Valley began a precipitous slide toward the eventual abandonment of a homeland that they had occupied for more than one thousand years. This volume is a long-awaited summary of one of the most important data-recovery projects in Southwest archaeology, synthesizing thousands of pages of data and text published in seven volumes of contract reports. The authors—all leading authorities in Hohokam archaeology who played primary roles in this revolution of understanding—here craft a compelling argument for the eventual collapse of Hohokam society in the late fourteenth century as seen from one of the largest and seemingly most influential irrigation communities along the lower Salt River. Drawing on extremely large and well-preserved collections, the book reveals startling evidence of a society in decline as reflected in catchment analysis, archaeofaunal assemblage composition, skeletal studies, burial assemblages, artifact exchange, and ceramic production. The volume also includes a valuable new summary of the archival reconstruction of the architectural sequence for the Pueblo Grande platform mound. With its wealth of data, interpretation, and synthesis, Centuries of Decline represents a milestone in our understanding of Hohokam culture. It is a key reference for Southwest archaeologists who seek to understand the Hohokam collapse and a benchmark for anyone interested in the prehistory of Arizona.
Download or read book Restoring Colorado River Ecosystems written by Robert W. Adler and published by Island Press. This book was released on 2012-06-22 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
