A characterization of seasonal pools in Central Oregon's high desert

Creator:: Dlugolecki, Laura
Abstract:: Seasonal wetlands in arid and semi-arid lands provide an important source of surface water in otherwise dry lands. Central Oregon's high desert, located in the Northern Great Basin (NGB) is dotted with hundreds of seasonal pools, locally called playas. The playas hold water or snow during parts of winter and...

The economic impacts of sagebrush steppe wildfires on an eastern Oregon ranch

Creator:: Maher, Anna T.
Abstract:: The relative success of restoration practices on cheatgrass infested sagebrush steppe lands in the Great Basin can affect the probability of crossing an ecological threshold and have economic effects on cattle ranches using federal rangelands. Cheatgrass invasion implies an increase in the risk of fire, which in turn increases the...

Morphological characteristics of ponderosa pine and lodgepole pine regeneration nine years after stand density reduction at three sites in central Oregon

Creator:: Michel, Alexa K.
Abstract:: Without the natural occurrence of fire in ponderosa pine forests of the western US, lodgepole pine has started to dominate regeneration in many forest stands and may be gradually replacing ponderosa pine over time. This development, however, conflicts with recent efforts in this region to restore old-aged, open ponderosa pine...

The thermal characteristics of hydrologically intact Type C and E streams in eastern Oregon

Creator:: Hopkins, Karl T.
Abstract:: Many streams in eastern Oregon are listed as water quality impaired on the basis of water temperature. However, it is often difficult to predict water temperature for these streams even if there are no anthropogenic impacts. We measured air and water temperature and stream characteristics on three Type C and...

Management and marketing strategies for high desert beef ranches in Eastern Oregon

Creator:: Panasuk, Eugene Duane
Abstract:: Ranchers in the high desert area of Eastern Oregon traditionally market their calves when they are weaned in late fall. This is the time when the market prices for calves are at a seasonal low. In this study the economic feasibility of various alternative management and marketing strategies for the...

The influence of environmental and physical factors on the thermal patterns of headwater streams

Creator:: Carr, Craig A.
Abstract:: A case study was performed in 2000 and 2001 to characterize the thermal pattern of four morphologically similar eastern Oregon streams and to identify the physical and environmental factors that expressed significant and functionally viable relationships with stream temperature (daily maximum, daily minimum and daily rate of heating). Stream and...

Susceptibility of select salmonids to Myxobolus cerebralis and effects of exposure on anadromous salmonids in Oregon

Creator:: Sollid, Sarah A.
Abstract:: Myxobolus cerebralis, a myxozoan parasite of salmonids, is the causative agent of whirling disease. The parasite is considered widespread throughout northeastern Oregon in the Grande Ronde and Imnaha River basins where threatened and endangered salmonid populations exist. The work presented in this thesis comprises several studies that assess the effects...

Twenty-year changes in riparian bird communities of east-central Oregon

Creator:: Ellis, Michael S.
Abstract:: Over the last 50 years, riparian zones in the semi-arid West have gained recognition as disproportionately important habitats for both breeding bird communities and agricultural operations. Despite growing interest in exploring avian-habitat relationships in these systems to better inform land management, few studies have attempted to describe temporal changes in...

Persistence of western juniper resource islands following canopy removal

Creator:: Miwa, Christopher
Abstract:: Western juniper (Juniperus occidentalis) cover has more than doubled within the last century and currently occupies over 9 million acres in the Intermountain West. Encroachment has altered the spatial distribution of soil nutrients and plants in these systems, forming nutrient enriched 'resource islands,' under tree canopies. The purpose of this...
