Book excerpt: Excerpt from Modeling Acreage Changes in Forest Ownerships and Cover Types in the Southeast One weakness of the expert opinion approach has been that the questions addressed are not empirically linked to objective and independently verifiable criteria (sackman Sackman (1974) concluded that the technique is essentially unreliable and scientifically unvalidated. Armstrong (1978) was also critical of this type of approach. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

Book excerpt: The objective of this study was to develop a system based on economic criteria for projecting changes in land use areas. The total land base was partitioned among three classes of private forest owners and crop, pasture/range, and urban/other uses in the southeastern United States. The fraction of the land base in an owner/use was hypothesized to be a function of the ratio of the land rent for that owner/use relative to an average rent index for all owners/uses. Systems of econometric equations for the six owner/use classes were estimated by physiographic region: Coastal Plain, Piedmont, and Mountains. The data comprised a pooled cross-sectional/time series, with observations drawn at four time points from the 21 forest survey units in the Southeast. Population, personal income, and land commodity incomes were the major significant variables in the land owner/use equations. Changes in population and personal income levels have contributed to a decline in farm forest acreage and a corresponding increase in miscellaneous private forest acreage. Projections of forest acreage trends with the systems of land owner/use equations indicate a continued drop in farm forest acreage. Miscellaneous private forest acreage is projected to continue to increase, in part because of real personal income levels that are forecast to triple by the year 2040. Projections of acreage changes for the five major forest types by ownership in each physiographic region, using a Markov type model, point to a substantial reduction in natural pine acreage. Transition probabilities among forest types were estimated from forest survey remeasurement data and are conditional with respect to the application of certain management practices. The importance of exogenous forces (e.g., population) for forest acreage trends suggests the need to improve coordination with land use modeling for other sectors. Also needed are the integration of forest acreage modeling with that for forest type transition, timber inventory projection, and harvest estimation in an interregional framework.

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.
