Book Synopsis Ice Age Mammals of the San Pedro River Valley, Southeastern Arizona by : Andrew William Amann
Download or read book Ice Age Mammals of the San Pedro River Valley, Southeastern Arizona written by Andrew William Amann and published by . This book was released on 1998-01-01 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twelve thousand years ago the grasslands of the San Pedro River Valley of southern Arizona, teemed with herds of horse, camel, mastodon, mammoth, and long-horned bison. Prey animals such as dire wolf, jaguar, cougar, and bear thinned the herds. Paleo-Indians, the Clovis people, followed the herds picking off the young, crippled or weak. The colorful and well-illustrated, easy-to-read text pays special attention to extinct mega-fauna. This book shines a light on a transient ecology and evolving environment in the midst of global climate change at the end of the last ice age.
Book Synopsis The San Pedro River by : Roseann Beggy Hanson
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.

Available in PDF, EPUB and Kindle. Book excerpt: “We must! Or we all will die here in these miserable Starving Mountains. They are out there, I know they must be.” A pair of youths on the cusp of manhood bring The People across the great moving sand belt onto the Great Plains. A young woman is tested greatly by the Bison Spirit and found acceptable to lead The People back to the ways of their ancestors. But Basket is only half the way; they must be reunited. Soul brothers ripped asunder as evil claws its way in. Only Basket and Star Child can save the people and drive the evil away so that The People reach their destiny. At the end of the Younger Dryas—11,500 years ago—the rain returned. The Great Plains again supported vast herds of bison: bison antiquuis. The People were living in fragmented groups at the edge of starvation, but gradually, they began to adapt to a new way of life and spread from south Texas to North Dakota. They were the Folsom Culture.

Book Synopsis The Desert Grassland by : Mitchel P. McClaran
Download or read book The Desert Grassland written by Mitchel P. McClaran and published by University of Arizona Press. This book was released on 2023-05-23 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mixed grass and shrub vegetation known to scientists as desert grassland is common to the basins and valleys that skirt the mountain ranges throughout southwestern North America, extending from Arizona, New Mexico and Texas down through thirteen Mexican states. This variegated ground cover is crucial to life in an arid environment. The Desert Grassland offers the most comprehensive study to date of these flora and the rich biotic communities they support. Leading experts in geography, biology, botany, zoology, and geoscience present new research on the desert grassland and review a vast amount of earlier work. They reveal that present-day grasses once grew in the ice-age forests that existed in these areas before the climate dried and the trees vanished and how the intensity and frequency of fire can influence the plant and animal species of the grassland. They also document how the influence of humans—from Amerindians to contemporary ranchers, public land managers, and real estate developers—has changed the relative abundance of woody and herbaceous species and how the introduction of new plants and domesticated animals to the area has also affected biodiversity. The book concludes with a review of the attempts, both failed and successful, to reestablish plants in desert grasslands affected by overgrazing, drought, and farm abandonment. Meticulously researched and copiously illustrated, The Desert Grassland is a major contribution to ecological literature. For advanced lay readers as well as students and scholars of history, geography, and ecology, it will be a standard reference work for years to come.

Book Synopsis The Ribbon of Green by : Robert H. Webb
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.

Book Synopsis Requiem for the Santa Cruz by : Robert H. Webb
Download or read book Requiem for the Santa Cruz written by Robert H. Webb and published by University of Arizona Press. This book was released on 2021-11-30 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: In prehistoric times, the Santa Cruz River in what is now southern Arizona saw many ebbs, flows, and floods. It flowed on the surface, meandered across the floodplain, and occasionally carved deep channels or arroyos into valley fill. Groundwater was never far from the surface, in places outcropping to feed marshlands or ciénegas. In these wet places, arroyos would heal quickly as the river channel revegetated, the thriving vegetation trapped sediment, and the channel refilled. As readers of Requiem for the Santa Cruz learn, these aridland geomorphic processes also took place in the valley as Tucson grew from mud-walled village to modern metropolis, with one exception: historical water development and channel changes proceeded hand in glove, each taking turns reacting to the other, eventually lowering the water table and killing a unique habitat that can no longer recover or be restored. Authored by an esteemed group of scientists, Requiem for the Santa Cruz thoroughly documents this river—the premier example of historic arroyo cutting during the late nineteenth and early twentieth centuries, when large floodflows cut down through unconsolidated valley fill to form deep channels in the major valleys of the American Southwest. Each chapter provides a unique opportunity to chronicle the arroyo legacy, evaluate its causes, and consider its aftermath. Using more than a collective century of observations and collections, the authors reconstruct the circumstances of the river’s entrenchment and the groundwater mining that ultimately killed the marshlands, a veritable mesquite forest, and a birdwatcher's paradise. Today, communities everywhere face this conundrum: do we manage ephemeral rivers through urban areas for flood control, or do we attempt to restore them to some previous state of perennial naturalness? Requiem for the Santa Cruz carefully explores the legacies of channel change, groundwater depletion, flood control, and nascent attempts at river restoration to give a long-term perspective on management of rivers in arid lands. Tied together by authors who have committed their life’s work to the study of aridland rivers, this book offers a touching and scientifically grounded requiem for the Santa Cruz and every southwestern river.
