The objective of this study was to measure the consequences of alternative
forest management intensification programs. These consequences
include future harvest levels, silvicultural labor and capital
requirements, and the income and employment generated directly and indirectly.
The system utilizes the Timber Resource Economic Estimation
System (TREES) model, a harvest scheduling...
An analytical algorithm to formulate a sparser set of adjacency constraints than the conventional algorithm is proposed. Utilizing matrix algebra applied to an adjacency matrix, constraints are systematically and efficiently derived by the proposed algorithm. The proposed algorithm is proved to provide a true set of adjacency constraints in the...

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...
Harvesting productivity rates and costs were determined for three
silvicultural treatments used in commercial ground-based thinning of
young stands to achieve timber management objectives and enhance
wildlife habitat. Treatment definitions were based on residual trees
per acre (tpa) after thinning. The treatments were light thin (115
residual tpa), light thin...
This dissertation investigates livelihood and land use change dynamics in a community at the farm-forest periphery in highland Ethiopia. I use interviews and livelihood assessment data to compare the strategies used by members of different wealth groups to negotiate and maintain access to forest resources, and integrate socioeconomic, bio-physical and...
Three data sets were examined to determine the costs with and without
constrained forest management practices. Two adjacent sites in the Coast Range of
Oregon were studied. One of the units was broadcast burned while the adjacent site was
left unburned. The stands were projected for growth and yield in...
Young Douglas-fir stands were commercially thinned to achieve vegetation- and wildlife-related objectives. Harvesting and forwarding production and costs were compared among three mechanized thinning treatments: light thin [(115 residual trees per acre (tpa)], light thin with 0.5-ac openings (92 residual tpa), and heavy thin (53 residual tpa). The sites were...
