The study of highlead logging operations through the use of
statistical models is investigated, and their potential use for estimating
and control of operations examined.
During the preliminary phases of the study 16 work elements
and 26 influencing variables are identified and measurement criteria
developed for each. A coding system...
A descriptive model of community stability is developed which
can be used to gauge the achievement of community stability in
federal sustained yield units. Community stability is defined which
provides the framework on which the model was created.
The achievement of the four goals of the 1944 Sustained Yield
Act...
To abstract the fundamental market structures of stumpage sold from the Siuslaw National Forest, a three-equation structural model with different assumptions on private cut was empirically derived. Under the private cut price-fixed assumption, the structural model can be simplified as a single-equation model with stumpage price as dependent variable and...
A dynamic programming algorithm (MS PATH) was used to develop a stand level optimization model, FPS Optimizer. The model incorporates a late-seral constraint on the profit maximizing objective function utilizing a four-descriptor structural index as a proxy. This index, the 'Old-Growth Index', rates the late-seral structural quality of a given...
Competitive bid sales of U.S. Forest Service in the Pacific Northwest
timber resources have significant effects on the economies of
Oregon, Washington, and Idaho. These sales contribute to the economic
vitality of small regions or communities dependent upon timber as a primary
resource input. Any changes in the price or...
The number of sawmills in the coastal lumber-producing area
of British Columbia diminished from 364 In 1955 to 162 in 1968. In
the interior of the province the reduction in plant numbers was from
2125 to 740. Over the same period lumber production in the province
increased from 4.9 billion...
