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...

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...

Management Strategies for Small, Structurally Diverse & Income-Generating Forests

Creator:: Geisel, Julian
Abstract:: Parcellization of the rural landscape threatens the provision of social, ecological and economic benefits to society due to loss of economies of scale. A continued provision requires new approaches to forest management for multiple, interconnected goals. I used interviews, archival records and field measurements to learn how select, experienced owners...

Elucidating Key Aspects of the Biology of Select Species of Snail-killing Flies (Diptera: Sciomyzidae) in Oregon

Creator:: Alzahrani, Fares
Abstract:: Members of the family Sciomyzidae, known as snail-killing or marsh flies, are unique amongst insects in that the vast majority of reared species feed exclusively on mollusks and as a result their biological control potential has been well documented in the scientific literature. However, in North America there is a...

Canopy gaps affect the shape of Douglas-fir crowns in the western Cascades, Oregon

Creator:: Seidel, Dominik, Ruzicka, Kenneth J., and Puettmann, Klaus
Abstract:: Silvicultural regimes that aim at an increased stand structural diversity typically promote small-scale heterogeneity in horizontal and vertical structures, e.g. through the creation of gaps. We used terrestrial laser scanning (TLS) to investigate impacts of altered growing conditions on trees adjacent to artificial gaps as compared to responses of trees...

Distribution, habitat associations, and conservation status of Pacific fisher (Pekania pennanti) in Oregon.

Creator:: Barry, Brent R.
Abstract:: Fishers (Pekania pennanti) are medium sized mustelids endemic to North America. Two fisher populations persist in Oregon: an indigenous population in southwestern Oregon, and a reintroduced population in the southern Cascade Mountains. Despite candidacy for listing under the Endangered Species Act, current information on fisher populations in Oregon is scarce....
