Road networks, timber harvest, and the spread of Phytophthora root rot infestations of Port-Orford-cedar in southwest Oregon

Creator:: Clark, William C.
Abstract:: Phytophthora lateralis is the causal agent of cedar root rot, a fatal forest pathogen whose principal host is Chamaecyparis lawsoniana (Port-Orford-cedar), a predominantly riparian-restricted endemic tree species of ecological, economical, and cultural importance to coastal Oregon and California. Local scale distribution of P. lateralis is thought to be associated with...

Geographic distributions of prey of the northern spotted owl in the central western Cascades, Oregon, 1988-2009

Creator:: Smoluk, Alexis
Abstract:: Spatial variation in the diet of the northern spotted owl (Strix occidentalis caurina) influences owl home ranges, and understanding this relationship will aid managers in forest management prescriptions that influence spotted owl recovery. This study describes the spatial variation in owl diet based on 4183 prey collected at 114 owl...

A method for remotely monitoring glaciers with regional application to the Pacific Northwest

Creator:: Medley, Brooke
Abstract:: An integrative method for monitoring glacier geometry change and mass balance is presented and applied to the Pacific Northwest, USA. Acting as a baseline for interpretation of future changes in glacier size and shape, we first derive a new inventory of regional glacier cover using remotely sensed data. To investigate...

Using reanalysis data to characterize Arctic and Sub-Arctic glaciers

Creator:: Ourada, Quin
Abstract:: The net mass balance fluctuations of Arctic and Sub-Arctic glaciers, north of 47.5° North latitude, are described over a 45-year period from 1957 to 2002 using two parameters derived from a gridded climatology reanalysis. Variability among 185 measured glaciers was represented according to two main components. The first component represents...

Do vigorous young forests reduce streamflow? Results from up to 54 years of streamflow records in eight paired-watershed experiments in the H. J. Andrews and South Umpqua Experimental Forests

Creator:: Perry, Timothy D.
Abstract:: This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...

Photorealistic landscape visualization : A step towards a Digital Earth

Creator:: Dey, Ryan M.
Abstract:: A Digital Earth is a visualization tool that uses the latest technologies to embed vast quantities of geographic data into easily understood information. By creating three-dimensional landscape visualizations that look as photorealistic as current technology allows, it becomes possible to see, explore, and spatially understand parts of the Earth as...

Production of an animated cartography sample for teaching and instruction, with musings on the nature and usefulness of animated maps

Creator:: Whaley, Kristine A.
Abstract:: Animated cartography is still a new field. It has been experimented with for years, but it has not gained general usage except partially in use by the news media. Nevertheless, certain subjects cry out for displaying the patterns of movement over time, such as historical patterns of migration and settlement,...

The visualization of perspective systems and iconology in Dürer’s cartographic works : an in-depth analysis using multiple methodological approaches

Creator:: Wörz, Adèle Lorraine
Abstract:: This dissertation uses a new methodological approach for an in-depth analysis of three cartographic works. Studies within the discipline of the history of cartography have followed various methodologies throughout the past century. This dissertation argues that in order to come to a more complete understanding of how maps were produced...

Trends in streamflow from old growth forested watersheds in the western Cascades

Creator:: Moore, Kathleen M.
Abstract:: Increasing temperatures in western North America are expected to result in a decline in winter snowpacks, earlier snowmelt, and a shift in the timing of streamflows, with an increasing fraction of streamflows occurring earlier in the water year and drier conditions during the summer. However, few streamflow datasets have associated...
