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...

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...

Recovery of High-graded Nothofagus Forests: Building Resilience Through Theory and Practice

Creator:: Soto, Daniel P.
Abstract:: The increasing human demands on natural resources, in combination with uncertainties about ecosystem dynamics due to global change, has led the scientific community to conclude that new approaches in understanding of ecological systems are needed to tackle environmental issues in an efficient manner. One development that has received more attention...

Impacts of Tree-species Composition and Diversity on Ecosystem Services in Plantations of the Coastal Pacific Northwest: Assessing Values, Trade-offs, and Synergies

Creator:: Himes, Austin
Abstract:: The objective of this dissertation was to examine trade-offs and synergies between multiple ecosystem services derived from plantation forests in the coastal Pacific Northwest. I accomplished this in five chapters. In the first chapter I provided background information for the study. In the next chapter I set the context for...

Vegetation response following thinning in young Douglas-fir forests of western Oregon : can thinning accelerate development of late-successional structure and composition?

Creator:: Beggs, Liane R.
Abstract:: Across western Oregon, Washington, and British Columbia, forest management practices over the past century reduced the amount of late-successional forest while simultaneously increasing the amount of young (less than 80 years old), managed Douglas-fir (Pseudotsuga menziesii) dominated forests. Recently, concerns over loss of late-successional habitat pushed management objectives on public...

Patterns in understory vegetation communities across canopy gaps in young, Douglas-fir forests of western Oregon

Creator:: Fahey, Robert T.
Abstract:: Canopy gap formation is a major factor contributing to maintenance of overstory species diversity and stand structure in forests and may be integral to development of understory shrub and herb layers as well. Acknowledgement of gap formation as a fundamental feature of natural forests has led to consideration of gaps...

Managing Douglas-fir Mortality: Case Studies from Western Oregon

Creator:: Campbell, Lewis
Abstract:: An increase in frequency and severity of hot, dry summers has been associated with a dramatic shift in the coniferous forests of western Oregon’s valleys, especially on the privately-owned properties along the low-elevation edges of these valleys. Various conifer species, including Douglas-fir (Pseudotsuga menziesii), are declining in these forests, leaving...

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...

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...

The Effect of Canopy Cover and Wildfire Smoke on Near-Surface Temperatures

Creator:: Brackett, Amanda
Abstract:: Recent shifts from clearcutting to partial retention harvesting on many ownerships and the importance of microclimate dynamics on biotic responses to regional climate highlight the need to understand how microclimate conditions in forest understories differ across gradients of partial overstories. This study compares below-canopy near-surface temperatures at 2cm above ground...
