Soil compaction from low ground-pressure, torsion-suspension logging vehicles on three forest soils

Creator:: Froehlich, Henry A. and Oregon State University. Forest Research Laboratory
Abstract:: Monitoring soil density on three sites during repeated trips with a high-speed skidder showed that: During the first 20 trips, soil density primarily increased between depths of 2 to 4 inches; Density increased most during the first few trips; Density continued to increase slowly in amount and depth with the...

Designing skid trail systems to reduce soil impacts from tractive logging machines

Creator:: Froehlich, Henry A., Aulerich, D. E., and Curtis, R.
Abstract:: Logging on skid trails restricted to 10 percent or less of the harvested stand can reduce the area of compacted soil by at least two-thirds, In a comparative study, productivity of Douglas-fir logs per hour was just as great In an area with designated trails as In an adjacent area...

Soil compaction on a mechanized timber harvest operation in eastern Oregon

Creator:: Zaborske, Richard R.
Abstract:: The use of mechanized harvest equipment has been increasing as an economical method to harvest small diameter timber. While the use of this equipment is increasing, little is known about associated soil compaction. In particular, little information exists on soil compaction caused by feller--bunchers. This study measured soil compaction caused...

Fine organic debris and dissolved oxygen in streamed gravels in the Oregon Coast Range

Creator:: Skaugset, Arne E.
Abstract:: Intragravel organic loading and intragravel dissolved oxygen were studied to determine the relationship between timber harvesting adjacent to first-, second-, and third-order streams and intragravel water quality. Twenty watersheds in the central Coast Range of western Oregon were studied of which five were undisturbed, nine were partially harvested, and six...

Report of dam at Chitwood mill on Haxel Creek, a tributary of Thornton Creek

Creator:: Waldron, Kenneth D. and Oregon Fish Commission. Shellfish Program
Abstract:: Describes an investigation of a dam at a millpond near the village of Chitwood, Oregon. The dam was on Haxel Creek, a tributary of Thornton Creek, a tributary of the Yaquina River. Includes a hand-drawn map of the area.

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...

Analysis and operational considerations of biomass extraction on steep terrain in western Oregon

Creator:: Flint, Benjamin R.
Abstract:: The development of bioenergy from biomass has dominated the minds of forest engineering researchers over the last decade. One of the main themes that has been generated from that research is that bioenergy from biomass has major operational hurdles to overcome before becoming economically feasible. More directly, the impact of...

The geomorphic significance of log steps in forest streams of the Oregon Coast Range

Creator:: Marston, Richard A.
Abstract:: A log step develops when large woody debris extends across the active channel, creating a change in the water surface elevation as the stream spills over the log step. By forming a series of vertical falls, log steps reduce the amount of potential energy available for conversion to kinetic energy...

A study of the effect of logging on aquatic resources : a progress report, 1960-66

Creator:: Phillips, Robert W., Campbell, Homer J., Hug, Wayne L., Claire, Errol W., and Oregon. State Game Commission. Research Division
Abstract:: This report measures the effects of logging on the production and yield of Coho salmon, coastal cutthroat, and steelhead trout in small coastal streams. It contains descriptions of the physical and biological environment before logging, and describes some immediate effects of logging, such as such as a decrease in dissolved...

Municipal water source turbidities following timber harvest and road construction in western Oregon

Creator:: Grizzel, Jeffrey D.
Abstract:: Many municipalities throughout western Oregon rely upon forested watersheds as a source for domestic water supply. These watersheds are commonly managed by state or federal agencies or private corporations for timber production. Activities related to forest management within municipal watersheds have the potential to adversely affect water quality. Timber harvesting...
