Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Vegetation Dynamics on the Mountains and Plateaus of the American Southwest written by John Vankat and published by Springer Science & Business Media. This book was released on 2013-05-27 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: In a two-year study, the National Academy of Sciences' Committee on Developing Strategies for Rangeland Management examined at length the scientific, political, economic, legal, and social issues arising from the BLM's stewardship role. This book, reporting the findings and recommendations of the NAS committee, contains over eighty professional papers presented at workshops designed to assess forage allocation, inventory of rangeland resources, impact of grazing intensity and specialized grazing systems on the use and value of rangeland, manipulative range improvements, application of socioeconomic techniques to range management decision making, and political and legal aspects of range management.
