A comparative economic analysis between log scaling practices

Creator:: Lewis, Charles Stewart
Abstract:: Many centers of population in the Pacific Northwest are dependent upon employment in the forest based industries. Mary of these timber dependent communities look to the public forests for their raw wood requirements. In some localities the installed capacity has outstripped the local wood supply. This necessitates reaching into other...

A comparative study of three log rules commonly used in the Pacific Northwest, U.S.A.

Creator:: Paixao, Julio De Castro
Abstract:: A comparative study was done on data collected by Weyerhaeuser Company on l,6144 second-growth Douglas-fir, Pseudotsuga menziesii, trees. The variable used in the study was the percent difference, positive or negative, between the volumes given by each of three different log rules and the standard tree volumes determined by Weyerhaeuser...

An evaluation of an inventory projection system : TRIM model predictions vs. forest inventory field measurements in North Carolina

Creator:: Mills, John R.
Abstract:: As part of the effort to evaluate TRIM (Timber Resource Inventory Model) for the next RPA National Assessment, a study was conducted using natural pine stands in North Carolina. TRIM has been used for regional timber supply studies in both the Pacific Northwest and the South (Southern Timber Supply Study)....

Probability proportional to size sampling of Douglas-fir from aerial photography

Creator:: Rogers, Roger Allan
Abstract:: This experiment was designed to investigate the use of volume estimations from aerial photography and probability proportional to size (PPS) sample selection in the development of a practical sampling design for timber volume estimation on small land areas of Pacific Northwest Douglas -fir (Pseudotsuga menziesii, Franco). The major problem of...

An evaluation of the use of tarif tables in second growth Douglas-fir

Creator:: Marshall, David D.
Abstract:: The Washington State Department of Natural Resources' Comprehensive Tree-Volume Tarif Tables are a set of preconstructed local volume tables. This can increase "on plot" efficiency since only diameters are necessary to obtain volumes after the proper table for the given diameter/height relationship is accessed. The tables are accessed and indexed...
Resource Type:: Masters Thesis

Disaggregative and individual-tree growth models in theory and application

Creator:: Ritchie, Martin W.
Abstract:: Disaggregative and individual-tree/distance-independent modeling methods are compared and contrasted. Differences between the two are related to differences in functional and apparent resolution and may be illustrated using aggregation theory. When considering models of different levels of resolution describing a given phenomenon, invariance with respect to the aggregation implied (symmetry) may...
