Book Description
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.

Area Changes for Forest Cover Types in the United States, 1952 to 1997, with Projections to 2050
Author: Ralph J. Alig
Publisher:
ISBN:
Category : Forest dynamics
Languages : en
Pages : 112
Book Description
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.

Area Changes in U.S. Forests and Other Major Land Uses, 1982 to 2002, with Projections to 2062

ISBN: 1437938698

Languages : en
Pages : 105
Book Description
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.

Resource and Market Projections for Forest Policy Development
Author: Darius M. Adams
Publisher: Springer Science & Business Media
ISBN: 1402063091
Category : Technology & Engineering
Languages : en
Pages : 599
Book Description
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.
