Small, independent logging contractors can benefit
from cost control and cost planning. This report
details the labor and equipment cost components of a
logging crew. Records, both required and available for
determining costs, are discussed. Recommended costing
procedures are illustrated. Although the study took
place in the Pacific Northwest, the...
A problem of interest to forest managers is the optimum arrangement of truck roads and landings for economical logging operations.
This problem becomes more complex if,a combined yarding and swinging
operation is considered. I,t is possible to formulate a mathematical
model to express the cost per unit volume for a...
A model (called MERLIN) is presented that can allow the resource manager to consider the combined effects of silvicultural treatments and their effect on expected logging production and costs. This integrated analysis takes place within the framework of personal computer software readily available to most managers. This integration is accomplished...
The Forest and Rangeland Renewable Resources Planning Act of 1974 requires the U.S. Forest Service to periodically evaluate the U.S. timber situation. An important part of such studies is the determination of forest product imports from Canada through evaluation of Canadian log and product supply conditions. Other studies have projected...
In the Pacific Northwest, loggers are faced with the problems of changing from logging old growth to second growth. This is due to the shrinking old growth timber supply and increased entry into the· second growth stands. Beuter (1 980) indicated that in western Oregon 70.2 percent by volume of...
An extension of the sensitivity analysis of linear programming, called parametric programming is used in determining optimal sawtimber logging system mix. The five logging systems under study are manual log-length, system, log-length processor and harvester systems, manual tree-length system and tree-length harvester system. In conditions where it is not exactly...
LOCCOST is an interactive computer program that
predicts stump to mill logging costs, stumpage and net
present value of a harvest based on stand data, pond value
and logging parameters, entered by the user. The program is
intended for use by foresters to evaluate the economics of
different stand management...
This report supplements Research Bulletin 18 (1975) of the Forest Research Laboratory, School of Forestry, Oregon State University. Bulletin 18 summarized analyses of data for the first field season of the Pansy Basin Study. This Bulletin extends those analyses to the second, and final, field season. Time-study observations during the...
