Context matters : A multi-scale assessment of riparian tree response to upslope density reduction

Creator:: Ruzicka, Kenneth J., 1982-
Abstract:: Forest management is rapidly undergoing a transformation from a discipline based on efficient commodity production to one for multiple uses, especially on federally managed land in the United States. This new management paradigm has challenged silviculturists to develop and adapt forest management techniques that can deal with increased demands. Using...

Mapping disturbance interactions from earth and space : insect effects on tree mortality, fuels, and wildfires across forests of the Pacific Northwest

Creator:: Meigs, Garrett W.
Abstract:: Given the vital role of forest ecosystems in landscape pattern and process, it is important to quantify the effects, feedbacks, and uncertainties associated with forest disturbance dynamics. In western North America, insects and wildfires are both native disturbances that have influenced forests for millennia, and both are projected to increase...

Examining ectomycorrhizal communities of ponderosa pine and lodgepole pine in the south-central Oregon pumice zone

Creator:: Garcia, Maria Osuna
Abstract:: Background information is presented that provides historical perspectives on the field of mycology in the Pacific Northwest and its role in forest management. The series of events and decisions that have led to previous studies (or lack of studies) in the field also dictate the directions of current research. Culture,...

Analysis of the regional carbon balance of Pacific Northwest forests under changing climate, disturbance, and management for bioenergy

Creator:: Hudiburg, Tara W.
Abstract:: Atmospheric carbon dioxide levels have been steadily increasing from anthropogenic energy production, development and use. Carbon cycling in the terrestrial biosphere, particularly forest ecosystems, has an important role in regulating atmospheric concentrations of carbon dioxide. US West coast forest management policies are being developed to implement forest bioenergy production while...

Bird-vegetation relationships across ten years after thinning in young thinned and unthinned Douglas-fir forests

Creator:: Yegorova, Svetlana
Abstract:: Bird-vegetation associations are a base for bird conservation and management, as well as for predictions of the effects of resource management and climate change on wildlife populations. A recent shift in forest management priorities from timber production to native species' habitat conservation on federal lands has emphasized the need to...

Overstory density and disturbance impacts on the resilience of coniferous forests of western Oregon

Creator:: Neill, Andrew R.
Abstract:: A trait based approach was used to assess impacts of overstory density and thinning on understory vegetation components related to wildlife habitat. The relationship between overstory basal area and understory vegetation for species grouped by traits, such as production of flowers, fleshy-fruit and palatable leaves, was characterized in thinned and...

Exploration of statistical methods for synthesizing the effects of variable-retention harvesting on multiple taxa

Creator:: Lam, Tzeng Yih
Abstract:: Variable-retention harvesting was proposed to reduce loss of biodiversity and ecosystem processes associated with late-seral Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest. The Demonstration of Ecosystem Management Options experiment was established to test this hypothesis. Analysis presents various challenges to drawing statistical inferences about treatment effects. This dissertation explored...

The effects of mechanical damage on residual coastal Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) following commercial thinning

Creator:: Kiser, James D.
Abstract:: Commercial thinning operations can result in damage to residual stems. A literature review revealed that little was known about the effects of residual logging wounds with regard to rotation-age commercial conifers, particularly Douglas-fir. An experiment to examine fungal colonization of Douglas-fir following logging damage showed that while damage was significant...

Carbon dynamics following landscape fire: influence of burn severity, climate, and stand history in the Metolius Watershed, Oregon

Creator:: Meigs, Garrett W.
Abstract:: Fire is a fundamental disturbance that drives terrestrial and atmospheric carbon dynamics. Previous studies have quantified fire effects on carbon cycling from local to global scales but have focused nearly exclusively on high-severity, stand-replacement fire. Since 2002, variable-severity wildfires have burned more than 65 000 ha across the east slope...

Disturbance and dynamics of riparian forests in southwestern Oregon

Creator:: Messier, Michael S.
Abstract:: Fire exclusion has been associated with structural and compositional changes in many upland forests of the western United States, but little is known about the impacts on riparian forests, portions of the landscape protected for habitat and water quality. For this study, I characterized the historic disturbance and tree recruitment...
