Competition release and climate change effects on a moisture-demanding tree species in a dry system

Creator:: Seager, S. Trent
Abstract:: Climate change and the increase in meteorological drought have generated global concern over the persistence of ecosystems already in decline from decreased moisture. Evidence suggests dryland ecosystems have been more impacted by drought because of their tightly coupled growth-water relationships and high sensitivity to environmental shift. Removal of competing vegetation...

Optimal spatial-dynamic resource allocation facing uncertainty : integrating economics and ecology for invasive species policy

Creator:: Hall, Kim M.
Abstract:: The spatial and temporal behavior of invasive species spread implies that optimal management strategies involve decisions over space and time. Dispersal and propagule pressure are two primary drivers of the spatial-temporal ecological process of species invasion. In the case of riparian communities, stream flow drives the dispersal of vegetation propagules....

The effects of forest fuel reduction on fire severity and long-term carbon storage

Creator:: Mitchell, Stephen Richard
Abstract:: Two forest management objectives being debated in the context of federally managed landscapes in the US Pacific Northwest involve a perceived trade-off between fire restoration and C sequestration. The former strategy would reduce fuel (and therefore C) that has accumulated through a century of fire suppression and exclusion that has...

Spatial patterns of fuel management activities and their effects on wildfire behavior

Creator:: Kim, Young-Hwan
Abstract:: Fuel management has been used as an effective local strategy to reduce the undesirable consequences of wildfires. Many efforts toward scheduling of fuel management activities across a broader landscape have been proposed, with the hope of achieving larger landscape-scale management effects. However, scheduling of fuel management treatments across the broader...

Quaking aspen persistence in three Oregon landscapes

Creator:: Seager, S. Trent
Abstract:: Quaking aspen (Populus tremuloides) is an important tree species in the western United States and there has been much concern about its persistence. In this thesis, I report on aspen in a portion of its range that has not been previously evaluated: the eastern and western slopes of the Central...

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...

Influence of silvicultural treatments, overstory, and understory vegetation on quaking aspen (Populus tremuloides) regeneration in southeastern Idaho

Creator:: Muñoz, Bethany L.
Abstract:: Quaking aspen (Populus tremuloides Michx.) is known to be a widely distributed, shade-intolerant and short-lived hardwood found in both seral, even-aged and stable, uneven aged stands. There have been reports of extensive aspen mortality, crown thinning, and branch dieback across North America that have been linked to the occurrence of...

Fire severity and vegetation response to fire in riparian areas of the Biscuit and B&B Complex Fires, Oregon

Creator:: Halofsky, Jessica E.
Abstract:: Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...

Fire effects on vegetation diversity, structure, and successional dynamics in shrub-steppe and mixed conifer environments of the Hells Canyon, Idaho

Creator:: Havlina, Douglas William
Abstract:: The effects of fire severity on post-fire succession and shrub demography were quantified in shrub-steppe grasslands and subalpine forests in the Hells Canyon of the Payette National Forest, Idaho. Following the 1988 Eagle Bar Fire, species frequency, community diversity, fire adaptations, and stand ages were quantified at 12 plots in...
