Book Description
The book provides information essential for anyone interested in the ecology of the American Southwest, including land managers, environmental planners, conservationists, ecologists and students. It is unique in its coverage of the hows and whys of dynamics (changes) in the major types of vegetation occurring on southwestern mountains and plateaus. It explains the drivers and processes of change, describes historical changes and provides conceptual models that diagrammatically illustrate past, present, and potential future changes. All major types of vegetation are covered: spruce-fir, mixed conifer, and ponderosa pine forests, pinyon-juniper vegetation, subalpine-montane grassland, and Gambel oak and interior chaparral shrublands. The focus is on vegetation that is relatively undisturbed, i.e., in natural and near-natural condition, and how it responds to natural disturbances such as fire and drought, as well as to anthropogenic disturbances such as fire exclusion and invasive species

Book Description
The arrival of Anglo settlers in the 1870s marked the beginning of major vegetation changes in southeastern Arizona, including an increase in woody plants in rangelands, the degradation of riparian wetlands, and the spread of non-native plants. While many of these changes have already been linked to human land-use through comparative photographs and historic descriptions, it has long been presumed that changes in the region's climate have also contributed to vegetation change. Geographer Conrad Bahre now challenges the view that these vegetation changes are due to climatic change. Correlating his own field research with archival records and photographs, Bahre demonstrates that most of the changes follow some type of human disturbance, such as cattle grazing, fuelwood cutting, wildfire suppression, agriculture, and road construction. Indeed, all available evidence suggests that Anglo settlement brought unprecedented changes to the land. Vegetation change in the American West has long been an issue of concern. This careful scrutiny of one corner of that region—one of the most ecologically diverse areas of the United States—shows how poorly understood is the relationship between human activities and vegetation. More important, it introduces new techniques for differentiating between natural and anthropogenic factors effecting vegetation change that can be used to help ecologists understand vegetation dynamics worldwide.

Book Description
From the actions of Europeans in the seventeenth century to the real estate deals of the modern era, people making a living off the land in southern Arizona have been repeatedly robbed of their way of life. History has recorded more than three centuries of speculative failures that never amounted to much but left dispossessed people in their wake. This book seeks to excavate those failures, to examine the new social spaces the schemers struggled to create and the existing social spaces they destroyed. Landscapes of Fraud explores how the penetration of the evolving capitalist world-system created and destroyed communities in the Upper Santa Cruz Valley of Arizona from the late 1600s to the 1970s. Thomas Sheridan has melded history, anthropology, and critical geography to create a penetrating view of greed and power and their lasting effect on those left powerless. Sheridan first examines how OÕodham culture was fragmented by the arrival of the Spanish, telling how autonomous communities moving across landscapes in seasonal rounds were reduced to a mission world of subordination. Sheridan then considers the fate of the Tumac‡cori grant and Baca Float No. 3, another land grant. He tells the unbroken story of land fraud from Manuel Mar’a G‡ndaraÕs purchase of the ÒabandonedÓ Tumac‡cori grant at public auction in 1844 through the bankruptcy of the shady real estate developers who had fraudulently promoted housing projects at Rio Rico during the 1960s and Õ70s. As the Upper Santa Cruz Valley underwent a wrenching transition from a landscape of community to a landscape of fraud, the betrayal of the OÕodham became complete when land, that most elemental form of human space, was transformed from a communal resource into a commodity bought and sold for its future value. Today, Mission Tumac‡cori stands as a romantic icon of the past while the landscapes that supported it lay buried under speculative schemes that continue to haunt our history.

Book Description
Explore the controversial legal history of the formation of the United States Prestatehood Legal Materials is your one-stop guide to the history and development of law in the U.S. and the change from territory to statehood. Unprecedented in its coverage of territorial government, this book identifies a wide range of available resources from each state to reveal the underlying legal principles that helped form the United States. In this unique publication, a state expert compiles each chapter using his or her own style, culminating in a diverse sourcebook that is interesting as well as informative. In Prestatehood Legal Materials, you will find bibliographies, references, and discussion on a varied list of source materials, including: state codes drafted by Congress county, state, and national archives journals and digests state and federal reports, citations, surveys, and studies books, manuscripts, papers, speeches, and theses town and city records and documents Web sites to help your search for more information and more Prestatehood Legal Materials provides you with brief overviews of state histories from colonization to acceptance into the United States. In this book, you will see how foreign countries controlled the laws of these territories and how these states eventually broke away to govern themselves. The text also covers the legal issues with Native Americans, inter-state and the Mexico and Canadian borders, and the development of the executive, legislative, and judicial branches of state government. This guide focuses on materials that are readily available to historians, political scientists, legal scholars, and researchers. Resources that assist in locating not-so-easily accessible materials are also covered. Special sections focus on the legal resources of colonial New York City and Washington, DC—which is still technically in its prestatehood stage. Due to the enormity of this project, the editor of Prestatehood Legal Materials created a Web page where updates, corrections, additions and more will be posted.
