Download or read book Area Changes for Forest Cover Types in the United States 1952 to 1997 with Projections to 2050 written by Ralph J. Alig and published by . This book was released on 2004 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States has a diverse array of forest cover types on its 747 million acres of forest land. Forests in the United States have been shaped by many natural and human-caused forces, including climate, physiography, geology, soils, water, fire, land use changes, timber harvests, and other human interventions. The major purpose of this document is to describe area projections of forest cover changes on timberland areas of the United States, in support of the 2000 Resources Planning Act assessment by the USDA Forest Service. Forest area projections differ markedly by region, owner, and forest cover type. Although some regions such as the North are projected to have relatively small percentage changes in common types such as maple-beech-birch (less than 5 percent), others in the South have relatively large projected changes: reductions of 19 percent for upland hardwood on nonindustrial private forest timberlands and 58 percent on forest industry timberlands in the South Central region; and increases in excess of 25 percent for planted pine for both private ownerships in the South. Although the area of softwoods is projected to increase across many regions of the country, especially on forest industry lands, hardwoods will remain the dominant forest type on private lands.

This book was released on 2007-09-18 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: The text provides literature surveys on relevant modeling issues and policy concerns. It demonstrates the application of a modeling system using a "base case" 50-year projection and a small set of scenarios. These illustrate, for example, the effects of changes in public harvest policies, variations in investments in silviculture, and globalization. It is aimed at policy makers, researchers and graduate students who are building or using forest sector models.

Download or read book Mountain Resorts written by Julia LeMense and published by Routledge. This book was released on 2016-04-22 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountains are the home of significant ecological resources - wildlife habitat, higher elevation plant systems, steep slopes, delicate soils and water systems. These resources are subject to very visible and growing pressures, most of which are caused by the unique features of mountains. Using as case studies four mountain resorts in the US and Canada, this book analyzes the extent to which the law protects the ecological systems of mountains from the adverse impacts associated with the development, operation and expansion of resorts. In order to examine these issues, Mountain Resorts takes an interdisciplinary approach, with contributions from ecologists and lawyers who focus on ski-related activities, increasing four-season use of the mountains and expanding residential, commercial and recreational development at the mountains' base. Its analysis of an array of US and Canadian federal, state and local laws provides a multifaceted exploration of the intersection of ecology and the law at mountain resorts.
Download or read book Regional Cost Information for Private Timberland Conversion and Management written by Lucas S. Bair and published by . This book was released on 2006 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost of private timber management practices in the United States are identified, and their relationship to timber production in general is highlighted. Costs across timber-producing regions and forest types are identified by forest type and timber management practices historically applied in each region. This includes cost estimates for activities such as forest establishment practices such as reforestation and afforestation on crop and pastureland. Establishment costs for reforestation in the Southern United States are less than in other regions, although regional differences in establishment costs are less evident in hardwood than in softwood stands. Also, included in the list of timber management costs ate the intermediate management treatments of precommercial thinning, herbicide, and fertilizer application. Intermediate management treatments are less costly in the southern United States than in other regions. Trends in timber management costs reported as part of the management costs reporting.
Download or read book Regional Cost Information for Private Timberland written by Lacas S. Bair and published by DIANE Publishing. This book was released on 2007-09 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: These projections reflect the consequences of recent changes in the Alaska forest sector & trends in markets for Alaska products. With the cancellation of the long-term contracts & the closure of the two southeast Alaska pulp mills, demand for Alaska national forest timber now depends on markets for sawn wood & the ability to export manufacturing residues & lower grade logs. Four scenarios are presented that display a range of possible future demands. The range in annual demand for timber from Alaska national forests is 48 to 370 million board feet of logs annually. Areas of uncertainty includes the prospect of continuing changes in markets & competition, & the rates of investment & innovation in manufacturing in Alaska. Illustrations.

Book excerpt: This book, which contains 8 chapters, provides a framework for the general public, forest managers and policy makers to understand what factors need to be included when working towards using and protecting the world's forests so that they can be sustained. Topics covered include: historical perceptions and use of forests; the creation of today's forest landscapes by global societies; decision making related to forests becoming democratic and globalized; changing views about the ecology and conservation of forests; the historical and continuing impacts of human disturbances (i.e., air pollution, climatic change, salt injury, introduced plants, introduced insects, introduced pathogens, forest management activities and wars) on forests; the relevance of natural disturbances (i.e., wildfires, wind, extreme temperature and moisture, volcanic eruptions, pathogens, and insect and vertebrate pests) in maintaining sustainable forests; the relationship of human health to forest management; and the relationship among forests, humans and the carbon cycle. Case studies from Australia, Bolivia, Botswana, China, Iceland, India, Indonesia, Mexico, Nepal, Peru, the Philippines, Puerto Rico and the USA, are also included.
Download or read book Ecology and Management of Forest Soils written by Dan Binkley and published by John Wiley & Sons. This book was released on 2012-11-05 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest soils are the foundation of the entire forest ecosystem and complex, long-term interactions between trees, soil animals, and the microbial community shape soils in was that are very distinct from agricultural soils. The composition, structure, and processes in forest soils at any given time reflect current conditions, as well as the legacies of decades (and even millennia) of interactions that shape each forest soil. Reciprocal interactions are fundamental; vegetation alters soil physical properties, which influence soil biology and chemistry, which in turn influence the growth and success of plants. These dynamic systems may be strongly influenced by intentional and unintentional management, ranging from fire to fertilization. Sustaining the long-term fertility of forest soils depends on insights about a diverse array of soil features and changes over space and time. Since the third edition of this successful book many new interests in forest soils and their management have arisen, including the role of forest soils in sequestering carbon, and how management influences rates of carbon accumulation. This edition also expands the consideration of how soils are sampled and characterized, and how tree species differ in their influence on soil development. Clearly structured throughout, the book opens with the origins of forest soil science and ends with the application of soil science principles to land management. This new edition provides: A completely revised and updated Fourth Edition of this classic textbook in the field A coherent overview of the major issues surrounding the ecology and management of forest soils Global in scope with coverage of soil types ranging from the tropical rainforest soils of Latin America to the boreal forest soils of Siberia New chapters on Management: Carbon sequestration; Evidence-based approaches and applications of geostatistics, GIS and taxonomies A clear overview of each topic, informative examples/case studies, and an overall context for helping readers think clearly about forest soils An introduction to the literature of forest soil science and to the philosophy of forest soil science research This coherent overview of the major issues surrounding the ecology and management of forest soils will be particularly useful to students taking courses in soil science, forestry, agronomy, ecology, natural resource management, environmental management and conservation, as well as professionals in forestry dealing with the productivity of forests and functioning of watersheds.
