Investigations of runoff production and sedimentation on forest roads

Creator:: Wemple, Beverley C.
Abstract:: Forest roads constructed in steep mountain landscapes have been associated with a number of effects on hydrologic and geomorphic processes. This research examined the effects of forest roads on the flow of water and sediment in drainage basins in the Cascade range of western Oregon. A study conducted at the...

Climate, management, and forest type influences on carbon dynamics of West-Coast US forests

Creator:: Hudiburg, Tara M.
Abstract:: Net uptake of carbon from the atmosphere (net ecosystem production, NEP) is dependent on climate, disturbance history, management practices, forest age, and forest type. To improve understanding of the influence of these factors on forest carbon flux in the western U.S., a combination of federal inventory data and supplemental ground...

Full Text:: Oregon and Northern California during the 1990’s. The specific components studied were live and dead

Effects of harvest and roads on in-stream wood abundance in the Blue River Basin, western Cascades, Oregon

Creator:: Czarnomski, Nicole M.
Abstract:: Despite many studies of large wood in streams, few landscape scale studies have been conducted. Large-scale studies can reveal how the history of forest harvest and road building has influenced wood patterns in streams of the Pacific Northwest. This study examined the relationships between wood in streams, timber harvest, and...

Effects of thinning on forest-floor vertebrates and analysis of habitat associations along ecological gradients in Oregon coastal Douglas-fir forests

Creator:: Suzuki, Nobuya
Abstract:: Thinning has the potential to increase structural diversity of managed forests for wildlife. During 1994-1996, I conducted experimental and observational studies using pitfall trapping to assess short-term and potential long-term effects of thinning on abundance and reproduction of forest-floor vertebrates in Douglas-fir (Pseudotsuga menzeisii) forests of the Oregon Coast Range....

Relationships between plant associations and environment within McDonald-Dunn Forest

Creator:: Leavell, Daniel M.
Abstract:: I studied the relationship of environmental variables to six plant associations on McDonald and Paul M. Dunn Forests. Indirect gradient analysis was used to determine relationships. The plant associations were developed in a companion study by C.J. Hubbard (1991). McDonald-Dunn Forests are located north and northwest of Corvallis, Oregon. The...

Effects of input and redistribution processes on in-stream wood abundance and arrangement in Lookout Creek, western Cascades Range, Oregon

Creator:: Dreher, David Marshall
Abstract:: This study explored how selected input and redistribution processes affect the amount and arrangement of in-stream wood within the 64 km2 Lookout Creek watershed in the Andrews Forest, western Cascade Range, Oregon. A longitudinal inventory of in-stream wood was conducted over approximately 20 km of stream length in 2nd to...

Effects of burrowing by mountain beaver (Aplodontia rufa) on soil in a young forest in the Oregon Coast Range

Creator:: Russell, William Ogburn, 1964-
Abstract:: Soil effects from mountain beaver (Aplodontia rufa ) burrowing were investigated in Oregon Coast Range soils formed from Tyee sandstone. The potential for observed changes in soil to affect productivity was assessed. Soil horizons from mountain beaver mound soil and adjacent unmounded profiles were collected with a monolith-type quantitative sampler....

Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

Four centuries of soil carbon and nitrogen change after severe fire in a Western Cascades forest landscape

Creator:: Giesen, Thomas William
Abstract:: Fire is a major disturbance process in many forests. Long-term studies of the biogeochemical effects of fires, especially on soils, are very rare. Consequently, long-term effects of fire on soils are often hypothesized from short-term effects. In a chronosequence study, I studied 24 western Cascades (Oregon) forest stands thought to...
Resource Type:: Masters Thesis
Full Text:: (Oregon) forest stands thought to have been initiated in fire. Twelve of those burned about 150 years

The use of burned forest by breeding birds following the Biscuit Fire in southwest Oregon

Creator:: Donaghy Cannon, Michelle M.
Abstract:: Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...
