A comparison of productivity for whole tree, tree length, and log length skyline thinning in 35 year old Douglas-fir stands of western Oregon

Creator:

Putnam, Nathan E.

Abstract:

Whole tree and tree length thinning are two alternatives which are likely to be more productive and may prove to be more cost effective than conventional log length thinning. The purpose of this study was to evaluate and compare log length, tree length, and whole tree thinning techniques in terms...

Capstone Project
A simulation of the comparative costs and benefits of skyline strip thinning

Creator:

LeDoux, Chris B.

Abstract:

Strip thinning is recognized as a way of commercial thinning young-growth stands. strip thinning has been used worldwide. The purpose of this study was to explicitly evaluate the costs and benefits associated with skyline strip thinning in young Douglas-fir (Pseudotuqo menzesii Franco) stands in the Pacific Northwest and to compare...

The effects of swinging and sorting with a skidder on yarding and loading efficiency in small diameter Douglas-fir

Creator:

McIntire, John Charles

Abstract:

This study evaluated the impact of using a rubber-tired skidder to keep the landing clear by sorting and decking the logs along the road prior to loading by a self-loading truck. The evaluation was accomplished through detailed time studies conducted on a Koller K-300 yarder, a Crown Super 3000 self-loader,...

Capstone Project
Operational prebunching: a logger's application to reduce skyline thinning costs

Creator:

Zielinsky, Cary Russell

Abstract:

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...

Capstone Project
Cable thinning in young forests with average DBH of 5-8 inches : a case study

Creator:

Gabrielli, Robert Michael

Abstract:

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 percent western hemlock (Tsuga. heterophylla- (Raf.) Sarg.), 45 percent Douglas-fir (Pseudotsuga meuziesil...

Resource Type:

Capstone Project
An HP-75/HP--86 computer data collection system for recording and displaying logging equipment time studies

Creator:

Campbell, Thomas M.

Abstract:

Time studies of logging equipment are important to determine production rates, calculate logging costs and locate operating inefficiencies. However, using present time study techniques, they are also costly and time consuming to complete. This project will develop a new data gathering and storage technique using the HP-75 portable computer to...

Capstone Project
A method of selection of cable harvesting machines for Vermont

Creator:

Stirler, Dennis John

Abstract:

There is much interest in the State of Vermont in cable harvesting. Since there are no time studies available for cable harvesting with various machines in Vermont, it is necessary to arrive at production and cost levels by a different method. The method chosen for this paper is made up...
