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...

The use of remote sensing for characterizing forests in wildlife habitat modeling

Creator:: Vogeler, Jody C.
Abstract:: Spatially explicit maps of habitat relationships have proven to be valuable tools for conservation and management applications including evaluating how and which species may be impacted by large scale climate change, ongoing fragmentation of habitat, and local land-use practices. Studies have turned to remote sensing datasets as a way to...

Fire ecology and management in plant communities of Malheur National Wildlife Refuge, southeastern Oregon

Creator:: Young, Richard P.
Abstract:: This research assesses prescribed burning as a habitat management technique in wetlands and associated upland communities of Malheur National Wildlife Refuge, southeastern Oregon. Experimental burns were conducted to evaluate fire behavior and effects in wetland and upland habitats, and, fire effects on Cirsium arvense. Wetland plant communities were monotypic stands...

Conflict and cooperation at the public-private interface : a case study of fire management in eastern Oregon

Creator:: Bergmann, Stefan Andrew
Abstract:: Cooperation across ownership boundaries is critical to most conservation efforts in mixed ownership landscapes. Where owner objectives vary widely, as at public-private landownership boundaries, cooperation can be especially challenging. This research explores the opportunities and challenges for cooperative fire management among public and private forest managers in the John Day...

Temporal and spatial variability of historic fire frequency in the southern Willamette Valley foothills of Oregon

Creator:: Robbins, Danielle
Abstract:: A crossdated fire history was reconstructed for a 1562 km2 area in the southern Willamette foothills of Oregon, using fire scars and tree origin years from twelve sites. The purpose of this study was to determine fire frequency for each site and to quantify temporal and spatial variability of fire...

Groundwater elevations and temperature adjacent to a beaver pond in central Oregon

Creator:: Lowry, Michael M.
Abstract:: This study was designed and implemented to observe the spatial and temporal dynamics of groundwater levels and temperatures adjacent to a beaver pond in semi-arid central Oregon. The study site was located on the eastern boundary of Painted Hills National Monument along Bridge Creek, a tributary to the John Day...

Community analysis of the Wyoming big sagebrush alliance and functional role of Wyoming big sagebrush

Creator:: Davies, Kirk W.
Abstract:: This study consisted of two research projects in the Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis (Beetle & A. Young) S.L. Welsh) alliance, the most extensive of the big sagebrush complex in the Intermountain West. In the first project, we intensively sampled 107 relatively undisturbed, late seral Wyoming big sagebrush...

An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...

Role of propagule pressure and priority effects on plant establishment during restoration of invaded shrub-steppe

Creator:: Schantz, Merilynn C.
Abstract:: Biological plant invasions are diminishing the ecological integrity and function of ecosystems worldwide. A primary example of this is in the Great Basin of the United States, where invasive annual grasses, like cheatgrass (Bromus tectorum L.) and medusahead (Taeniatherum caput-medusae L. Nevski), are dominating many sagebrush-steppe ecosystems. In these invaded...

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...
