Exploring the biology and monitoring techniques of two economically impactful Chrysobothris species in Oregon hazelnuts

Creator:: Rudolph, Erica
Abstract:: Chrysobothris mali Horn and C. femorata Olivier (Coleoptera : Buprestidae) are two flatheaded wood boring beetle species that have become economically impactful pests in North American high value tree cropping systems. Both species are native to North America, with C. femorata occurring across the continent (Wellso and Manley 2007), whereas...

Management Strategies and Ethical Considerations for Controlling Phytophthora ramorum (sudden oak death): Application to Southern Humboldt County

Creator:: McClung, H. Rose
Abstract:: Humboldt Redwoods State Park in southern Humboldt County, California is a coastal redwood forest, a highly unique and valued ecosystem. It has many social, cultural, ecological, and economic values, including recreational benefits, heritage and aesthetic values, high biodiversity, nutrient cycling, and climate regulation. However, Humboldt County is at risk of...

Height-related trends in structure and function of Douglas-fir foliage

Creator:: Woodruff, David R.
Abstract:: This dissertation investigated the impacts of tree height upon a range of physiological and structural characteristics of Douglas-fir foliage; relationships between structural and functional trends with height; and compensatory mechanisms that mitigate height-related growth constraints. Height-related trends in foliar physiological and anatomical characteristics were examined both within trees as well...

Groundwater and stormwater treatment at western wood preserving facilities : an analysis of current treatment methods

Creator:: Ragan, Anita M.
Abstract:: The Pacific Northwest is blessed with an abundance of precipitation. This rainfall, however, can have important consequences for industries that must process the resulting stormwater for proper discharge. This is particularly true of wood treatment facilities. Past management practices at wood preserving facilities located in the Western United States create...

An Assessment of Black-backed Woodpecker (Picoides arcticus) Vital Rates in Green and Burned Forests within a Pyrodiverse Landscape Mosaic

Creator:: Kerstens, Mark E.
Abstract:: Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...

Post-fire recreation management in the Mt. Jefferson Wilderness

Creator:: Brown, Ryan N. K.
Abstract:: Natural events such as wildfires, floods, and storms can significantly alter the short-term structure and functioning of natural systems. Recreation in wilderness areas is one instance in which individuals are directly exposed to post-disturbance landscapes. Consequently, public land managers may be faced with a different set of challenges stemming from...

Contributions of Epicormic Branches and Delayed Adaptive Foliage in Coastal Douglas-fir under Variable Density Management Regimes

Creator:: Punches, John W.
Abstract:: The contribution of delayed adaptive reiteration to crown maintenance was explored across a wide range of adjacent open space conditions in early-mature (approximately 60 year old) Douglas-fir located on the eastern slope of Oregon’s Coast Range. The stands had experienced uniform thinning in 1964-65 and 1980-81 to release dominant and...

Evaluating Multi-objective Trade-offs in Mature Douglas-fir (Pseudotsuga menziesii) Stands of Western Oregon

Creator:: Williams, Neil G.
Abstract:: Contemporary forest management involves a more extensive and diverse suite of management objectives than was the case throughout much of the Twentieth Century. Heightened public and political awareness of local and global biodiversity decline, and interest in arresting these trends, has increased the emphasis on broad-based biodiversity conservation as an...

Measuring and Modeling the Structure of Coniferous Trees with Point Clouds Data

Creator:: Fang, Rong
Abstract:: Coniferous trees are a major North American crop that has been intensively managed for its commercial value, while also serving as critical habitat for abundant wildlife and as carbon sinks. Having diverse functions, North American temperate coniferous forests have become a research hotspot for numerous scientific studies aiming to integrate...
