Production rates and costs for cable, balloon, and helicopter yarding systems in old-growth Douglas-fir

Creator:: Dykstra, Dennis P. and Oregon State University. Forest Research Laboratory
Abstract:: This report describes initial results of a yarding time study for the Pansy Basin Study, a cooperative research project designed to test the performance of skylines, balloons, and helicopters operating under various conditions of timber and terrain, and over a range of silvicultural and landscape design prescriptions. Observations during the...

Examination of moisture content variation within an operational wet deck

Creator:: Schimleck, Laurence, Love-Myers, Kim, Sanders, Joe, Raybon, Heath, Daniels, Richard, Andrews, Edward, and Schilling, Erik
Abstract:: Many forest products companies in the southeastern United States store large volumes of round-wood under wet storage. Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to...

"Waving Wand" Broadcast Hand Application of Herbicides: Technical Basis and Usage

Creator:: Newton, Michael, Cole, Elizabeth C., and Barry, Jack W.
Abstract:: The waving-wand system of broadcast chemical application implemented in swath widths to 40 ft (>12 m) is capable of simulating broadcast deposition patterns for herbicides similar to those delivered by helicopter. Drop sizes vary from center to edge of swaths, which can range from >1,000 to 5,000 microns (μ). Any...

A study of a stocking survey system and the relationship of stocking percent as determined by this system to number of trees per acre

Creator:: Bever, Dale N.
Abstract:: This study was initiated and designed, first, to determine the reliability of the stocking survey system, and, second, to construct free hand curves which would give the ratio of percent of stocking to number of trees per acre.

Heat conditioning of veneer blocks

Creator:: Resch, Helmuth, Parker, R., and Oregon State University. Forest Research Laboratory
Abstract:: Short-term heating of softwood veneer blocks temporarily softens the wood so that it can be peeled more readily. Heating reduces the depth of lathe checks and the likelihood of splitting and thereby increases the quality and quantity of veneer recovered. The softwood-plywood industry conventionally conditions blocks three ways: steaming blocks...
