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 Murray Springs written by Caleb Vance Haynes and published by University of Arizona Press. This book was released on 2007-04-17 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Murray Springs Site in the upper San Pedro River Valley of southeast Arizona is one of the most significant Clovis sites ever found. It contained a multiple bison kill, a mammoth kill, and possibly a horse kill in a deeply stratified sedimentary context. Scattered across the buried occupation surface with the bones of late Pleistocene animals were several thousand stone tools and waste flakes from their manufacture and repair. Because of the unique occurrence of an algal black mat that buried the Clovis-age surface immediately after abandonment, the distributional integrity of the artifacts and debitage clusters is exceptional for Paleoindian sites. Excavation of the Clovis huntersÕ camp 50 to 150 meters south of the kills revealed artifactual evidence typical of hunting camp activity, including hide working and weapons repair. Impact flakes conjoining with Clovis points clearly tied the camp to the bison kill. The unique nature of the site and this comprehensive study of the excavated material constitute one of the most important contributions to our knowledge of Paleoindian hunters in the New World.
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.

Download or read book Mission of Sorrows written by John L. Kessell and published by University of Arizona Press. This book was released on 1970 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mission of Guevavi on the Santa Cruz River in what is now southern Arizona served as a focal point of Jesuit missionary endeavor among the Pima Indians on New Spain's far northwestern frontier. For three-quarters of a century, from the first visit by the renowned Eusebio Francisco Kino in 1691 until the Jesuit Expulsion in 1767, the difficult process of replacing one culture with another—the heart of the Spanish mission system—went on at Guevavi. Yet all but the initial years presided over by Father Kino have been forgotten. Drawing upon archival materials in Mexico, Spain, and the United States—including accounts by the missionaries themselves and the surviving pages of the Guevavi record books—Kessell brings to life those forgotten years and forgotten men who struggled to transform a native ranchería into an ordered mission community. Of the eleven Black Robes who resided at Guevavi between 1701 and 1767, only a few are well known to history. Others—such as Joseph Garrucho, who presided more years at Guevavi than any other Padre; Alexandro Rapicani, son of a favorite of Sweden's Queen Christina; Custodio Zimeno, Guevavi's last Jesuit—have the details of their roles filled in here for the first time. In this in-depth study of a single missionary center, Kessell describes in detail the daily round of the Padres in their activities as missionaries, educators, governors, and intercessors among the often-indifferent and occassionally hostile Pimas. He discusses the Pima uprising of 1751 and the events that led up to it, concluding that it actually continued sporadically for some ten years. The growing ferocity of the Apache, the disastrous results of certain government policies—especially the removal of the Sobaípuri Indians from the San Pedro Valley—and the declining native population due to a combination of enforced culture change and epidemics of European diseases are also carefully explored. The story of Guevavi is one of continuing adversity and triumph. It is the story, finally, of explusion for the Jesuits and, a few short years later, the end of Mission Guevavi at the hands of the Apaches. In Mission of Sorrows Kessell has projected meticulous research into a highly readable narrative to produce an important contribution to the history of the Spanish Borderlands.
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.
