Shovel logging and soil compaction : a case study

Creator:: Floch, Rick F.
Abstract:: Shovel logging is a relatively new ground-based method of yarding tinther. It involves moving logs from stump to landing by successive swinging with a hydraulic excavator modified into a log loader by replacing the shovel bucket with a grapple. Loaders used in shovel yarding can weigh in excess of 100,000...

The DEERHORN case study: a production and cost analysis of a single-grip harvester and small cable yarder performing a thinning/salvage operation in eastern Oregon.

Creator:: Brown, Cameron G.
Abstract:: Land managers in the Blue Mountains of eastern Oregon are currently faced with large areas of forest with health problems and extreme levels of fuel loading in the stand and on the forest floor. These conditions resulted from a combination of insect infestations, past management practices and the elimination of...

Skyline thinning production rate equations using the thin simulation model

Creator:: Starnes, Lawson W.
Abstract:: This paper shows how ten easy-to-use linear skyline thinning production rate equations were obtained by transforming existing but more cumbersome turn time equations using the THIN simulation model [11). The equations provide reasonable approximations of delay-free hourly production for several cable yarders operating skyline thinnings under a variety of conditions....

Tactical forest planning using the scheduling and network analysis program (SNAP II)

Creator:: Mafera, Thomas E.
Abstract:: Approximately 750 million acres, or one-third, of the total area in the United States is in forest land. The United States Forest Service, a 34,000 person agency of the Department of Agriculture, is responsible for the management of roughly 20 percent of the forest land in the United States. The...

Critique of seven helicopter timber sales with recommendations for improved planning

Creator:: Petaisto, Inga T.
Abstract:: The focus of this study centers around the economic, technical, and environmental effects analysis of seven helicopter timber sales on four different national forests in Oregon and Washington. This paper is a constructive critique of these seven sales based on the author's personal observations and data collected from planning documents,...

A mobility model for tracked vehicles

Creator:: Gleason, Karl H.
Abstract:: A semi-empirical mobility model is presented which predicts tracked vehicle performance in timber harvesting applications. The interactions between the log load and the terrain, the log load and the vehicle, and the vehicle and the terrain cause resistances for the vehicle. The mobility model calculates these resistances, comparing them to...

LOGCOST a harvest cost model for southwestern Idaho

Creator:: Giles, Robert Steven
Abstract:: 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...

An economic analysis of pavement damage caused by studded tires in Oregon

Creator:: Gray, Judith Ann
Abstract:: This report frames the debate over studded tires in terms of economic principles of marginal cost pricing and efficient resource allocation. In the absence of a user tax, the pavement damage caused by studded tires results in inefficient pricing because social costs associated with the damage are excluded from the...

An expert system for softwood lumber grading

Creator:: Zeng, Yimin
Abstract:: The focus of this research is to develop a prototype expert system for softwood lumber grading. The grading rules used in the knowledge base of the system are based on Western Lumber Grading Rules 88 published by the Western Wood Products Association. The system includes 27 grades in Dimension, Select/Finish,...

Harvest system selection and design for damage reduction in noble fir stands : a case study on the Warm Springs Indian Reservation

Creator:: Matzka, Peter J.
Abstract:: 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 Heterobasidion annosum a rot pathogen on the Warm Springs Indian Reservation. The purpose of this study was to quantify...
