In-forest log segregation based on acoustic measurement of wood stiffness

Creator:: Amishev, Dzhamal Y.
Abstract:: To remain competitive, the forest products industry needs to look for new and innovative processes and technologies to not only reduce costs but also to recover more value through the entire seedling-to-customer forest products supply chain. It is well recognized that measuring wood properties of logs in real time during...

Forest harvesting impacts on coarse woody debris and channel form in central Oregon streams

Creator:: Knight, Stephen M.
Abstract:: Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...

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...

An integrated study of mechanical forest fuel reduction: quantifying multiple factors at the stand level

Creator:: Bolding, Michael Chad, 1977-
Abstract:: Recent catastrophic wildfires have forced the forest management community to develop new strategies for reducing forest fuels. Tightly spaced understory trees often create a fire ladder allowing surface fires to encroach into the crowns of overstory trees. This situation can lead to intensive, catastrophic, stand-replacement forest fires. Mechanical removal or...

Comparitive snow accumulation and melt during rainfall in forest and clearcut plots in western Oregon

Creator:: Berris, Steven Neil
Abstract:: A study was conducted to compare snow accumulation and melt during rainfall in adjacent forest and clearcut plots in the transient snow zone of the western Cascade Range in Oregon. Snow accumulation differences were determined by comparing the water equivalents of forest and clearcut snowpacks. During rain-on-snow periods, energy balances...

Wood properties and use of sensor technology to improve optimal bucking and value recovery of Douglas-fir

Creator:: Acuna, Mauricio A.
Abstract:: There are a number of wood properties which affect the quality of forest products such as lumber and pulp. Of these, wood density is considered by some to be the single most important physical characteristic because it is an excellent predictor of strength, stiffness, hardness, and paper-making capacities. Accurately assessing...

Scaling hydrologic impacts from road segments to a small watershed

Creator:: Royer, Timothy Adam
Abstract:: The impact of forest roads on the hydrology of forested watersheds has long been studied. While forest roads have been reported to alter storm runoff at the road segment scale, the potential for changes to be detectable at the small watershed scale has been debated. The purpose of this study...

Field and laboratory strength analysis of a forest road in NW Oregon and its association with the formation of ruts

Creator:: Bord, Andrea J.
Abstract:: A one-mile section of a newly constructed forest road in Northwest Oregon was analyzed for various aspects of subgrade and surface strength and their association with the formation of ruts during the first hauling season. Field and laboratory tests were completed on the road and the road materials to determine...

Examining effectiveness of Oregon’s forest practice rules for maintaining warm-season maximum stream temperature patterns in the Oregon Coast Range

Creator:: Fleuret, Jennifer Marie
Abstract:: Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas (RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...

Characterizing the spatial distribution of short duration, high intensity rainfall in the central Oregon Coast Range

Creator:: Goard, Deborah Lynn
Abstract:: Shallow, translational landslides occur naturally and are the dominant form of erosion in the Pacific Northwest and the Oregon Coast Range. These landslides are triggered during large, infrequent storms. Forest management activities, such as timber harvesting, can exacerbate the occurrence of these landslides. Understanding the relationship between the occurrence of...
