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...
Management restrictions are simulated on streamside acres owned by private interests in western Oregon to assess forest inventory and log market implications. A dynamic, nonlinear optimization model of western Oregon's softwood log market simulates the resource and economic impacts of set-aside and minimum harvest age restrictions on forest acreage within...
Forest Service projections of the long-term supply and demand
for forest products indicate that increasing importance will be
placed on the supply behavior of nonindustrial private forest owners
in the South. The inventory model on which these projections are
based may produce biased estimates of southern timber production,
however, as...
Subregional log market differences are defined and analyzed. Seven demand and seven supply centers are initially specified. Log demand factors inspected are mill capacity, processed wood species, cost and profitability conditions distinguished by product and subregion.
They are preliminarily linked to a regional market model through product price transmission. An...
This study utilizes the Timber Assessment Market Model (TAMM) to examine the differences in Canadian softwood lumber market forecasts arising from econometric versus activity analysis supply curves. A restricted profit function approach is applied to three lumber producing regions using the most recent data available on costs, prices, and output...
The Philippines relies heavily on timber product exports for its foreign exchange requirements. In recent years, however, it adopted log export restrictions as a hedge against the rapid depletion of its timber resources. Although conducted independently, its ASEAN partners (Malaysia and Indonesia), have likewise instituted similar restrictions on their own...
Although one of the most common problems facing the forest manager is the determination of management regime, there has been little effort to explicitly recognize the effect of harvesting technology and topography in the analysis. This study introduces a unified theory in harvesting in mountainous terrain which brings together silvicultural...
Few studies have examined the own-price elasticity of Canadian softwood lumber supply or output-adjusted factor demand elasticities over the past two decades, despite the utility of these measures in understanding producer response to tariffs, to market shifts (such as the decline in U.S. public harvest), and to changes in domestic...
In the field of forest planning, assumptions regarding the appropriate modeling of management behavior, translated through management prescriptions, minimum harvest ages, green-up periods, and other variables are needed if a stand-level optimization process is not used to guide the selection of stand management regimes Forest planners thus generally have a...
For many resource-based communities throughout Oregon the timber
industry plays an important role. In many of these areas, federal
land holdings comprise a large proportion of the area's land holdings.
Management decisions regarding resource use on the National Forest
lands can have a major influence on the stability of local...
