Examining ectomycorrhizal communities of ponderosa pine and lodgepole pine in the south-central Oregon pumice zone

Creator:: Garcia, Maria Osuna
Abstract:: Background information is presented that provides historical perspectives on the field of mycology in the Pacific Northwest and its role in forest management. The series of events and decisions that have led to previous studies (or lack of studies) in the field also dictate the directions of current research. Culture,...

Small mammal relationships with downed wood and antelope bitterbrush in ponderosa pine forests of central Oregon

Creator:: Smith, Troy G.
Abstract:: Downed wood and antelope bitterbrush (Purshia tridentata) are often managed on federal ponderosa pine (Pinus ponderosa) forests in central Oregon to prevent catastrophic wildfires and provide wildlife habitat. However, although much is known regarding the roles of downed wood and bitterbrush in wildfire behavior, little is known regarding the relationships...

Impact of Armillaria and annosus root diseases on stand and canopy structure, species diversity, and down woody material in a central Oregon mixed-conifer forest

Creator:: Fields, Kristen L. N.
Abstract:: White and grand fir are both valuable components of the mixed-conifer stand structure managed for late-successional reserves in central Oregon. However, they are often short-lived species because of high susceptibility to root diseases, defoliating insects, bark beetles, and wildfire. This study focuses on the effects of root diseases caused by...

Distribution of Live Biomass, Herbivory and Foliar Retention in Central Oregon Lodgepole Pine (Pinus contorta ssp. murrayana) Crowns

Creator:: Burke, Adam O.
Abstract:: Lodgepole pine (Pinus conorta) is a widely distributed forest type across western North America. Central Oregon lodgepole pine forests are ecologically unique when compared to other lodgepole pine ecosystems. Sierra lodgepole pine (Pinus contorta ssp. murrayana) is the dominant variety and often exists as the climax species on pumice soils,...

Archaeological investigation and technological analysis of the Quartz Mountain Obsidian Quarry, central Oregon

Creator:: Hatch, John B.
Abstract:: The Quartz Mountain Obsidian Quarry is located in the Southeast corner of the Bend Fort Rock Ranger District in central Oregon, approximately forty-five miles southeast of Bend, Oregon. The research of the Quartz Mountain Obsidian Quarry began with a literature search of other quarry sites in the area and the...

Impacts of post-fire salvage logging on soil chemistry, physical properties and bacterial community composition in a mixed-conifer forest in central Oregon

Creator:: Jennings, Tara Nicolle
Abstract:: Land managers, scientists, and the interested public are confronted with uncertainty about the impacts of salvage logging on soil productivity. In recent years, stand-replacing wildfires in the western United States have increased in frequency, prompting the need to evaluate the effect of post-fire treatments on forest ecosystem recovery. This study...

Economic Benefit from Allowing Wildfires to Burn in Federal East-Side Cascade Forests

Creator:: Gagnon, Aaron R.
Abstract:: In this thesis I examine the question: can allowing a wildfire to burn this year result in a net positive economic gain? To answer this question I created 2,500 multiple sets of paired scenarios (called a fire of interest) which consist of ignitions, vegetation growth, and timber harvest over the...

Influence of dwarf mistletoe (Arceuthobium americanum) on stand structure, canopy fuels, and fire behavior in lodgepole pine (Pinus contorta) forests 21-28 years post-mountain pine beetle (Dendroctonus ponderosae) epidemic in central Oregon

Creator:: Agne, Michelle C.
Abstract:: Lodgepole pine (Pinus contorta) forests are widely distributed throughout western North America. However, the lodgepole pine forests of central Oregon are ecologically unique to the region, with a mixed severity fire regime, low cone serotiny, and their occasional presence as a climax species. Most of the research conducted regarding the...

Potential effects of climate change and fire management on fire behavior and vegetation patterns on an east Cascades landscape

Creator:: Greaves, Heather E.
Abstract:: Climate exerts considerable control on wildfire regimes, and climate and wildfire are both major drivers of forest growth and succession in interior Northwest forests. Estimating potential response of these landscapes to anticipated changes in climate helps researchers and land managers understand and mitigate impacts of climate change on important ecological...

Managing for landscape resilience in the frequent-fire forests of central Oregon

Creator:: Platt, Emily K.
Abstract:: Wildfire in dry, frequent-fire forests is a pressing issue for natural resource managers, communities and politicians in the western United States. Area affected by wildfire has climbed steadily over the last twenty years and is expected to increase in the future. Recognition of the importance of both social and biophysical...

An analysis of two post-Mazama prehistoric flaked stone scatters in the upper Deschutes River basin of central Oregon

Creator:: McFarland, Janine Ruth
Abstract:: During the summer of 1986, an archaeological testing project was completed at seven prehistoric campsites primarily located in the upper Deschutes River Basin of central Oregon. Testing was focused on two low-density "lithic scatters", an archaelogical site type which is especially abundant in this obsidian-rich region but which, to date,...

Overstory composition and stand structure shifts within inter-mixed ponderosa pine and lodgepole pine stands of the south-central Oregon pumice zone

Creator:: Shuffield, Chaylon D.
Abstract:: Ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta var. murrayana) forests of south-central Oregon have been extensively researched over the last century. However, little information has been reported on overstory composition and stand structure shifts associated with fire exclusion within inter-mixed ponderosa pine and lodgepole pine stands of the...
