This thesis presents the idea for FORIN (Forest Roads Inventory), a computerized forest roads inventory system. FORIN is a tool to more efficiently inventory and manage information of forest roads. FORIN is intended for ...

This paper describes the results of a time-study conducted near Grand Ronde, Oregon, to determine the production rates and total harvesting costs of a cable thinning in a young stand. The stand had a species mix of 48 ...

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 determin ...

As lumber producers are faced with a diminished and increasingly expensive raw material, the need to maximize resource recovery will increase. Trim-ends (particularly from waned boards) often contain some of the highes ...

An experimental investigation of factors effecting scheduling a system of parallel, non-identical processors using a series of experimental designs was carried out. System variables included were processor capacities ...

Many high-elevation stands of noble fir in the northern Oregon Cascades are being actively managed. Forest managers are investigating different activities that will control stand impacts and the subsequent spread of He ...

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 progra ...

Measurement error (ME) is a component of any study involving the use of actual measurements, but is often not recognized or is ignored. The consequences of MEs on estimates of tree and stand attributes and the parameters ...

Western hemlock-Sitka spruce forests, where prior precommercial thinning has occurred, constitute one of the most productive young-growth management types along the Pacific Coast from Oregon to southeast Alaska. These s ...

A great deal of research has taken place in an effort to find more economically efficient yarding systems for commercial thinnings. Almost all of this research has centered on tractors or small yarders with limited c ...
