An analysis of the slackpulling forces encountered in manual thinning carriages

Creator:: Iff, Ronald H.
Abstract:: The popularity of gravity-return skyline logging systems is now increasing in the Western United States. Simplicity seems to be the basis for their success. While two drum yarders are most commonly used, ·some systems, such as the Wyssen, use only a single drum for yarding. Carriages commonly used with these...

Production rates and skidding cost of the FMC model 210 CA high-speed skidder

Creator:: Ohmstede, Robert H.
Abstract:: In recent years, inflation and a growing concern for soil compaction and environmental damage have affected both the forest manager and the logger. Balloons, helicopters, and skylines have been used to harvest timber and the results have been promising (Dykstra, 1975, 1976). However, the high cost of using these aerial...

Lipid-protein interactions : autoxidation studies involving freeze-dried methyl linolenate-gelatin foams

Creator:: Wehr, H. Michael and Sinnhuber, Russell O.
Abstract:: Studies involving freeze-dried methyl linolenate-gelatin foams indicate that the extent of lipid-protein interaction corresponds to the degree of autoxidation of the lipid fraction. It appears that approximately 11% of the malonaldehyde as defined by the 2-thiobarbituric acid test is firmly bound to the protein. The induction period of autoxidation is...

Slash-pile biomass estimations and Carbon Cycling in the Coastal Temperate Rainforest of the Pacific Northwest

Creator:: Winterbourne, Amber H. S.
Abstract:: Logging residue (slash) consists primarily of the branches and treetops of harvested merchantable timber; excluding snags, downed logs, and stumps. Residues may be scattered about the harvest unit, concentrated in slash-piles (SP), or both depending on the harvest method and equipment used. Accurate estimates of residue biomass are useful to...

An assessment of fall chinook salmon (Oncorhynchus tschawytscha) spawning habitat for present and pre-impoundment river conditions in a section of the John Day Reservoir, Columbia River

Creator:: Sheer, Mindi B.
Abstract:: The Columbia River system in the Pacific Northwest is currently comprised of a series of reservoirs, resulting from regulation of river flow due to a series of hydroelectric dams. A return to pre-dam conditions might improve salmon (Oncorhynchus sp.) survival rates and increase migration efficiency. This study modeled both historic...

SkidPC 2000: a mobility, production, and rut depth simulation program

Creator:: Spong, Ben D.
Abstract:: SkidPC 2000, written in Visual Basic Version 6.0, is an updated version of the 1987 DOS program that calculates the mobility and productivity of ground-based logging vehicles over a ground profile. As in the original program, the user enters the vehicle and operational conditions and the program will calculate the...

Preliminary planning of forest roads using ARC GRID

Creator:: Xu, Shenglin
Abstract:: Forest road planning is importaht in logging operations, because it can affect feasibility and cost of forest operations. Due to rapid advances in computer hardware, GIS software, and remote sensing techniques, computer forest road planning models using GIS are becoming practical. DEM data at 30 meter resolution are common and...

Aerial forest operations : mineral amendment project

Creator:: Cornell, Jennie L.
Abstract:: A helicopter operations problem was studied for a private forest landowner testing an experimental application of minerals on Douglas-fir (Pseudotsuga menziesil) in the Coast Range of Oregon to offset growth reductions from Swiss needle cast disease. A planning approach was needed to minimize costs for transportation and aerial application of...

A rapid survey method for native blue mud shrimp (Upogebia pugettensis) and its associated parasitic isopod, Orthione griffenis, in Alsea Bay, Oregon and alternative applications of this methodology

Creator:: Carter, Cameron S.
Abstract:: Declines or extinctions of the native intertidal estuary blue mud shrimp, Upogebia pugettensis, have been observed or are suspected in all of its populations over the species’ range. These declines are associated with the introduced Asian bopyrid isopod parasite, Orthione griffenis, which effectively castrates females. Baseline estimates of population abundances...

Earthquake Relocation in Three-Dimensional Velocity Models for Central Cascadia Continental Margin

Creator:: Ghorbani, Paria
Abstract:: We used data from Cascadia Initiative and Blanco Transform Fault Zone array of ocean bottom seismometers and hydrophone to look at the seismicity and specially depth of the Central Cascadia Continental Margin events. Events were detected and located automatically with Antelope software package (Boulder Real Time Technologies). We looked at...
