Forests to floodplain meadows : detrital dynamics in two headwater streams

Creator:: Brookshire, E. N. Jack
Resource Type:: Masters Thesis
Full Text:: River in Oregon. CPOM inputs to the forest reaches (187- 210 g m 2.yr') were dominated by litterfall

Ecological effects of spring and fall prescribed burning on basin big sagebrush : Idaho fescue--bluebunch wheatgrass communities

Creator:: Sapsis, David B.
Abstract:: The vegetation response of spring and fall prescribed fires in basin big sagebrush (Artemisia tridentata subsp. tridentata Nutt.)/Idaho fescue (Festuca idahoensis Elmer)--bluebunch wheatgrass (Agropyron spicatum Pursh. (Scribn. & Smith)) communities was measured at the John Day Fossil Beds National Monument in eastern Oregon. Objectives of the study were to quantify...

Relations among hydrology, soils, and vegetation in riparian meadows : influence on organic matter distribution and storage

Creator:: Dwire, Kathleen A.
Abstract:: Organic matter dynamics in riparian ecosystems are largely driven by interactions among hydrology, soil, and vegetation. In two riparian meadows, northeast Oregon, I examined the hypothesis that vegetation and soil characteristics in three plant communities - defined as wet, moist, and dry meadow - were strongly influenced by hydrological and...

Effects of prescribed fire and silvicultural activities on fuel mass and nitrogen redistribution in Pinus ponderosa ecosystems of central Oregon

Creator:: Shea, Ronald W.
Resource Type:: Masters Thesis

Ecology of the Salix and Populus species of the Crooked River National Grassland

Creator:: Busse, Kathryn Grace
Abstract:: Riparian communities dominated by members of the Salicaceae (Salix lasiandra, S. lutea, S. lemmonii, Populus trichocarpa, P. tremuloides and S. exiqua) were studied at the Crooked River National Grassland in central Oregon. The objectives of this study were to examine the relationships between the Salix and Populus species and microsite...

Vegetation composition and response to fire of native Willamette Valley wetland prairies

Creator:: Pendergrass, Kathy L. (Connelly)
Abstract:: Fires set by Native Americans were important in shaping and maintaining Willamette Valley prairie plant communities. With fire exclusion after Euro-American settlement in the 1840's, composition of the remaining prairies shifted toward shrub and tree dominance with a concomitant decline in endemic prairie plant populations. I hypothesize that by restoring...

The ecology of riparian ecosystems of Northeast Oregon : shrub recovery at Meadow Creek and the structure and biomass of headwater Upper Grande Ronde ecosystems

Creator:: Case, Richard L.
Abstract:: Riparian ecosystems play numerous and essential roles related to the quality and flow of water, and food/habitat for fish, and varieties of wildlife. Due to lateral and linear linkages throughout the landscape, these zones influence the integrity of the terrestrial as well as the entire aquatic-riverine ecosystem. Since Euro-American settlement...

Composition, structure, and biomass of cottonwood-dominated gallery forests along a successional gradient, Willamette River, Oregon

Creator:: Fierke, Melissa K.
Abstract:: Recognizing the importance of native black cottonwood-dominated riparian forests is especially important to preserve, protect, and manage for biodiversity in the Willamette River Valley. Species composition, structure, and biomass along a successional gradient from stand initiation to late succession of black cottonwood (Populus balsamfera L. subsp. trichocarpa (T. & G.)...

Long-term Fuel Succession in the Sagebrush-steppe

Creator:: Reis, Schyler Ainsworth
Abstract:: Historically fire has been the primary disturbance factor in the sagebrush-steppe. The settlement of the West by Euro-Americans, grazing by domestic livestock, and the concomitant spread of invasive species have altered the historical fire regime. Understanding the long-term vegetation structure and fuel succession of the various sagebrush-dominated communities of this...

Hydrologic and vegetation responses associated with restoration of wetlands in the Willamette Valley, Oregon

Creator:: Coleman, Gregory A.
Abstract:: I examined hydrological and plant community changes associated with the implementation of a restoration management plan in two riparian meadows located within an agricultural landscape of the central Willamette Valley, Oregon. I established exclosure fencing (a form of passive restoration) in one agricultural field and established fencing and plugged a...
