Tilling compacted forest soils following ground-based logging in Oregon

Creator:: Andrus, Charles W.
Abstract:: Implements for tilling compacted forest soils were tested on sites logged with ground-based machines in Oregon. The sites covered a variety of soil conditions ranging from a clay loam to a rock7 2C2 iplemeflts tested included disk harrows (four aies), brusa blades (three sites), standard subsoiler tines (two sites), wing.-...

The intrusion of logging debris into artificial gravel streambeds

Creator:: Garvin, William Fredrick
Abstract:: The objective of this study was to quantitatively describe the intrusion of logging debris into artificial gravel streambeds during conditions of low stream flow with a stable streambed, and begin an analysis of the effect of high flow and unstable streambeds. This study was initiated because prior studies indicated that...

The influence of contemporary forest harvesting on summer stream temperatures in headwater streams of Hinkle Creek, Oregon

Creator:: Kibler, Kelly Maren
Abstract:: Stream temperature is a water quality parameter that directly influences the quality of aquatic habitat, particularly for cold-water species such as Pacific salmonids. Forest harvesting adjacent to a stream can increase the amount of solar radiation the stream receives, which can elevate stream temperatures and impair aquatic habitat. Oregon Forest...

The effect of the size and orientation of large wood on pool volume in two Oregon Coast Range streams

Creator:: Lombard, Pamela
Abstract:: This study was conducted to determine how the size and orientation of large wood placed in streams in combination with peak flows, substrate and channel gradient affect pool volume, surface area and maximum depth in two coastal Oregon streams. Eighteen Douglas-fir (Pseudotsuga menziesii) logs were placed in each of two...

Streamside buffer strips : survival, effectiveness, and design

Creator:: Steinblums, Ivars John
Abstract:: Stream buffer strips are an important tool for protecting the stream environment. This research documents the losses from 40 stream buffer strips, in the Western Cascades of Oregon, established 1 to 15 years before the study. Predictive equations are developed which identify the major reasons for buffer strip losses. Losses...

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...

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...

Sediment production from forest roads in the upper Oak Creek Watershed of the Oregon Coast Range

Creator:: Amann, Joseph R.
Abstract:: Unpaved roads are sources of chronic sediment in forested watersheds. Bare soil on roads is exposed to erosion from rainfall and runoff Published research on sediment production from forest roads focuses primarily on road characteristics. Since water drives the mechanics of sediment transport, hydrologic variables should correlate with sediment production....

Sediment delivery to headwater stream channels following road construction and timber harvest in the Blue Mountains, Oregon

Creator:: Gill, Robert Earl
Abstract:: Many studies have focused on improving our understanding of the effects of timber harvesting activities on soil, water, and fisheries resources. Much of this work has led to the development and widespread use has often resulted in model applications that are outside the bounds in which the models were developed....

Response to Water Protection Rule changes in the Oregon Forest Practices Act : landowner/operator opinions and streamside conditions

Creator:: Hairston, Anne B.
Abstract:: This study assessed implementation of the 1994 Water Protection Rules in the Oregon Forest Practices Act from the perspective of Rule users and post-harvest riparian conditions. A 1993 evaluation found that under the previous rules over half of riparian conifers were removed during harvest, prompting concerns about future sources of...
