Available in PDF, EPUB and Kindle. Book excerpt: About two-thirds (504 million acres) of the Nation's forests are classed as timberland, productive forests capable of producing 20 cubic feet per acre of industrial wood annually and not legally reserved from timber harvest. The USDA's 1997 National Resource Inventory shows that, nationally, 11 million acres of forest, cropland, and open space were converted to urban and other developed uses from 1992 to 1997, as the national rate of urbanization increased notably compared to the 1982-92 period. Forest land was the largest source of land converted to developed uses such as urbanization. Urban and other developed areas are projected to continue to grow substantially, in line with a projected U.S. population increase of more than 120 million people over the next 50 years, with population growth occurring the fastest in the West and South. Projected increases in population and income will, in turn, increase demands for use of land for residential, urban, transportation, and related uses. An overall net loss in forest area in the United States since the early 1950s has been due to a combination of factors, but in more recent decades has been primarily due to conversion to urban and developed uses. Total forest area in the United States is projected to decrease by approximately 23 million acres by 2050, a 3-percent reduction from the 1997 forest area. Consistent with the projected slow net decline in U.S. forestland area, private timberland area is likewise projected to decline. Total area of U.S. private timberland is projected to decline by 4 percent by 2050. Industry timberland is projected to decrease by 3.0 percent by 2050, whereas timberland area on nonindustrial private lands is projected to decrease by 4.4 percent.

This book was released on 2011-05 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes area changes among major land uses on the U.S. land base for historical trends from 1982 to 2002 and projections out to 2062. Historically, 11 million acres of forest, cropland, and open space were converted to urban and other developed uses from 1992 to 1997 on non-federal land in the contiguous U.S. The largest percentage increase was in urban use, which grew by 10% or 7.3 million acres between 1997 and 2001. Forest land was the largest source of land converted to developed uses such as urbanization. Urban and other developed areas are projected to continue to grow substantially, in line with a projected U.S. population increase of more than 120 million people over the next 50 years. Figures.

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 Patterns and Processes in Forest Landscapes written by Raffaele Lafortezza and published by Springer Science & Business Media. This book was released on 2008-08-30 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing evidence suggests that the composition and spatial configuration – the pattern – of forest landscapes affect many ecological processes, including the movement and persistence of particular species, the susceptibility and spread of disturbances such as fires or pest outbreaks, and the redistribution of matter and nutrients. Understanding these issues is key to the successful management of complex, multifunctional forest landscapes, and landscape ecology, based on a foundation of island bio-geography and meta-population dynamic theories, provides the rationale to deal with this pattern-to-process interaction at different spatial and temporal scales. This carefully edited volume represents a stimulating addition to the international literature on landscape ecology and resource management. It provides key insights into some of the applicable landscape ecological theories that underlie forest management, with a specific focus on how forest management can benefit from landscape ecology, and how landscape ecology can be advanced by tackling challenging problems in forest (landscape) management. It also presents a series of case studies from Europe, Asia, North America, Africa and Australia exploring the issues of disturbance, diversity, management, and scale, and with a specific focus on how human intervention affects forest landscapes and, in turn, how landscapes influence humans and their culture. An important reference for advanced students and researchers in landscape ecology, conservation biology, forest ecology, natural resource management and ecology across multiple scales, the book will also appeal to researchers and practitioners in reserve design, ecological restoration, forest management, landscape planning and landscape architecture.

Download or read book Climate Change and United States Forests written by Peterson David L. and published by Springer Science & Business Media. This book was released on 2013-12-19 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a scientific assessment of the effects of climatic variability and change on forest resources in the United States. Derived from a report that provides technical input to the 2013 U.S. Global Change Research Program National Climate Assessment, the book serves as a framework for managing U.S. forest resources in the context of climate change. The authors focus on topics having the greatest potential to alter the structure and function of forest ecosystems, and therefore ecosystem services, by the end of the 21st century. Part I provides an environmental context for assessing the effects of climate change on forest resources, summarizing changes in environmental stressors, followed by state-of-science projections for future climatic conditions relevant to forest ecosystems. Part II offers a wide-ranging assessment of vulnerability of forest ecosystems and ecosystem services to climate change. The authors anticipate that altered disturbance regimes and stressors will have the biggest effects on forest ecosystems, causing long-term changes in forest conditions. Part III outlines responses to climate change, summarizing current status and trends in forest carbon, effects of carbon management, and carbon mitigation strategies. Adaptation strategies and a proposed framework for risk assessment, including case studies, provide a structured approach for projecting and responding to future changes in resource conditions and ecosystem services. Part IV describes how sustainable forest management, which guides activities on most public and private lands in the United States, can provide an overarching structure for mitigating and adapting to climate change.
