This book was released on 2009 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: contributors - biologists, ecologists, geomorphologists, historians, hydrologists, lawyers, and political scientists - weave together threads from their diverse perspectives to reveal the processes that shape the past, present, and future of the San Pedro's riparian and aquatic ecosystems. They review the biological communities of the San Pedro and the stream hydrology and geomorphology that affects its riparian biota. They then look at conservation and management challenges along three sections of the San Pedro, from its headwaters in Mexico in its confluence with the Gila River, describing legal and policy issues and their interface with science; activities related to mitigation, conservation, and restoration; and a prognosis of the potential for sustaining the basin's riparian system." "Complemented by a foreword written by James Shuttleworth, these chapters demonstrate the complexity of the San Pedro's ecological and hydrological conditions, showing that there are no easy --

Download or read book The Ribbon of Green written by Robert H. Webb and published by University of Arizona Press. This book was released on 2007 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woody wetlands constitute a relatively small but extremely important part of the landscape in the southwestern United States. These riparian habitats support more than one-third of the regionÕs vascular plant species, are home to a variety of wildlife, and provide essential havens for dozens of migratory animals. Because of their limited size and disproportionately high biological value, the goal of protecting wetland environments frequently takes priority over nearly all other habitat types. In The Ribbon of Green, hydrologists Robert H. Webb, and Stanley A. Leake and botanist Raymond M. Turner examine the factors that affect the stability of woody riparian vegetation, one of the largest components of riparian areas. Such factors include the diversion of surface water, flood control, and the excessive use of groundwater. Combining repeat photography with historical context and information on species composition, they document more than 140 years of change. Contrary to the common assumption of widespread losses of this type of ecosystem, the authors show that vegetation has increased on many river reaches as a result of flood control, favorable climatic conditions, and large winter floods that encourage ecosystem disturbance, germination, and the establishment of species in newly generated openings. Bringing well-documented and accessible insights to the ecological study of wetlands, this book will influence our perception of change in riparian ecosystems and how riparian restoration is practiced in the Southwest, and it will serve as an important reference in courses on plant ecology, riparian ecology, and ecosystem management.

Download or read book The San Pedro River written by Roseann Beggy Hanson and published by University of Arizona Press. This book was released on 2015-11-01 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Pedro River in southeastern Arizona not only features some of the richest wildlife habitat in the Southwest, it also is home to more kinds of animals than anywhere else in the contiguous United States. Here you'll find 82 species of mammals, dozens of different reptiles and amphibians, and nearly 400 species of birds—more than half of those recorded in the entire country. In addition, the river supports one of the largest cottonwood-willow forest canopies remaining in Arizona. It's little wonder that the San Pedro was named by the Nature Conservancy as one of the Last Great Places in the Northern Hemisphere, and by the American Bird Conservancy as its first Important Bird Area in the United States. Roseann Hanson has spent much of her life exploring the San Pedro and its environs and has written a book that is both a personal celebration of and a definitive guide to this, the last undammed and unchanneled river in the Southwest. Taking you from the San Pedro's entry into the U.S. at the Mexican border to its confluence with the Gila River about a hundred miles north, she devotes a separate chapter to each of seven sections of river. Each chapter contains an eloquent essay on natural and cultural history, laced with Hanson's own experiences, plus an exploration guide brimming with useful information: how to get to the river, finding hiking trails, camping and other accommodations, birdwatching tips, access to biking and horseback riding, and nearby historic sites. Maps are included for each stretch of river, and the text is illustrated throughout with drawings from Roseann's copious field notebooks. Along the 40 miles of the San Pedro Riparian National Conservation Area, a sanctuary protected by the Bureau of Land Management since 1988, Hanson shows how the elimination of cattle and off-road vehicles has restored the river corridor to a more natural condition. She tells of the impact of humans on the San Pedro, from Clovis hunters to American settlers to Washington bureaucrats, and shows how, as the river winds its way north, it is increasingly threatened by groundwater pumping and urbanization. In addition to the "discovery" sections of each chapter, Hanson has included species checklists for habitats and plants, birds, mammals, and reptiles and amphibians to make this a perfect companion for anyone exploring the area, whether as occasional tourist or frequent visitor. The book's blending of graceful prose and practical information shows that a river is the sum of many parts. Roseann Hanson will give you a special understanding—and perhaps a sense of stewardship—of this wild place.

Download or read book Alternative Futures for Changing Landscapes written by Carl Steinitz and published by Island Press. This book was released on 2003-01-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leading landscape architect and planner Carl Steinitz has developed an innovative GIS-based simulation modeling strategy that considers the demographic, economic, physical, and environmental processes of an area and projects the consequences to that area of various land-use planning and management decisions. The results of such projections, and the approach itself, are known as "alternative futures." Alternative Futures for Changing Landscapes presents for the first time in book form a detailed case study of one alternative futures project—an analysis of development and conservation options for the Upper San Pedro River Basin in Arizona and Sonora, Mexico. The area is internationally recognized for its high levels of biodiversity, and like many regions, it is facing increased pressures from nearby population centers, agriculture, and mining interests. Local officials and others planning for the future of the region are seeking to balance the needs of the natural environment with those of local human communities. The book describes how the research team, working with local stakeholders, developed a set of scenarios which encompassed public opinion on the major issues facing the area. They then simulated an array of possible patterns of land uses and assessed the resultant impacts on biodiversity and related environmental factors including vegetation, hydrology, and visual preference. The book gives a comprehensive overview of how the study was conducted, along with descriptions and analysis of the alternative futures that resulted. It includes more than 30 charts and graphs and more than 150 color figures. Scenario-based studies of alternative futures offer communities a powerful tool for making better-informed decisions today, which can help lead to an improved future. Alternative Futures for Changing Landscapes presents an important look at this promising approach and how it works for planners, landscape architects, local officials, and anyone involved with making land use decisions on local and regional scales.

Download or read book Water Follies written by Robert Jerome Glennon and published by Island Press. This book was released on 2012-09-26 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Santa Cruz River that once flowed through Tucson, Arizona is today a sad mirage of a river. Except for brief periods following heavy rainfall, it is bone dry. The cottonwood and willow trees that once lined its banks have died, and the profusion of birds and wildlife recorded by early settlers are nowhere to be seen. The river is dead. What happened? Where did the water go. As Robert Glennon explains in Water Follies, what killed the Santa Cruz River -- and could devastate other surface waters across the United States -- was groundwater pumping. From 1940 to 2000, the volume of water drawn annually from underground aquifers in Tucson jumped more than six-fold, from 50,000 to 330,000 acre-feet per year. And Tucson is hardly an exception -- similar increases in groundwater pumping have occurred across the country and around the world. In a striking collection of stories that bring to life the human and natural consequences of our growing national thirst, Robert Glennon provides an occasionally wry and always fascinating account of groundwater pumping and the environmental problems it causes. Robert Glennon sketches the culture of water use in the United States, explaining how and why we are growing increasingly reliant on groundwater. He uses the examples of the Santa Cruz and San Pedro rivers in Arizona to illustrate the science of hydrology and the legal aspects of water use and conflicts. Following that, he offers a dozen stories -- ranging from Down East Maine to San Antonio's River Walk to Atlanta's burgeoning suburbs -- that clearly illustrate the array of problems caused by groundwater pumping. Each episode poses a conflict of values that reveals the complexity of how and why we use water. These poignant and sometimes perverse tales tell of human foibles including greed, stubbornness, and, especially, the unlimited human capacity to ignore reality. As Robert Glennon explores the folly of our actions and the laws governing them, he suggests common-sense legal and policy reforms that could help avert potentially catastrophic future effects. Water Follies, the first book to focus on the impact of groundwater pumping on the environment, brings this widespread but underappreciated problem to the attention of citizens and communities across America.

Book excerpt: “Wonderfully written…Mr. Owen writes about water, but in these polarized times the lessons he shares spill into other arenas. The world of water rights and wrongs along the Colorado River offers hope for other problems.” —Wall Street Journal An eye-opening account of where our water comes from and where it all goes. The Colorado River is an essential resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado’s headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.–Mexico border where the river runs dry. Water problems in the western United States can seem tantalizingly easy to solve: just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on. The story Owen tells in Where the Water Goes is crucial to our future: how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert—and the disastrous consequences we face when any part of this tenuous system fails.

Download or read book The Davis Ranch Site written by Rex E. Gerald and published by University of Arizona Press. This book was released on 2019-04-30 with total page 825 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this new volume, the results of Rex E. Gerald’s 1957 excavations at the Davis Ranch Site in southeastern Arizona’s San Pedro River Valley are reported in their entirety for the first time. Annotations to Gerald’s original manuscript in the archives of the Amerind Museum and newly written material place Gerald’s work in the context of what is currently known regarding the late thirteenth-century Kayenta diaspora and the relationship between Kayenta immigrants and the Salado phenomenon. Data presented by Gerald and other contributors identify the site as having been inhabited by people from the Kayenta region of northeastern Arizona and southeastern Utah. The results of Gerald’s excavations and Archaeology Southwest’s San Pedro Preservation Project (1990–2001) indicate that the people of the Davis Ranch Site were part of a network of dispersed immigrant enclaves responsible for the origin and spread of Roosevelt Red Ware pottery, the key material marker of the Salado phenomenon. A companion volume to Charles Di Peso’s 1958 publication on the nearby Reeve Ruin, archaeologists working in the U.S. Southwest and other researchers interested in ancient population movements and their consequences will consider this work an essential case study.
