As ecological restoration expands as a practice, so does the complexity, cost, and scale of many projects. Higgs (2003) terms these projects technological and argues they limit meaningful community focal restoration practices, one component of good ecological restoration. The planned removals of two large dams on the Elwha River in Washington State provide a case study to investigate this theory. I conducted 18 in-depth interviews with community leaders and restoration practitioners in order to explore the question, “How do technological restoration projects enable or constrain community engagement, and in the case of the Elwha River, how might such engagement be enlarged?” This interpretive study suggests that technological restoration projects, particularly when managed by federal agencies, expand engagement through a broadened 1) public audience and 2) suite of engagement activities. I argue for a “focusing” of engagement activities, and propose a matrix for assessing opportunities for local community engagement.

xiv, 296 p. : ill. A print copy of this title is available through the UO Libraries under the call numbers: KNIGHT F853 .V64 2007 / This dissertation argues that Columbia River management and politics have been shaped ever since the New Deal by a conception of the Columbia River as the defining feature of the Pacific Northwest region. The study examines how that conception was developed, how it became institutionalized within and by a government agency, the Bonneville Power Administration, and what its impacts have been. Drawing on a mix of archival materials, published and unpublished secondary accounts, interviews, and the author's experience working on Columbia River policy, the dissertation shows that the definition of a Columbia River-centered Pacific Northwest was laid out in 1935 by the four-state Pacific Northwest Regional Planning Commission, influenced in part by a "regionalist" ideal of shared social and environmental well-being. It was institutionalized but narrowed into the federal BPA in 1937. Soon, a three-and-a-half-state Pacific Northwest consisting of Washington, Oregon, Idaho and western Montana was being knit together by shared transmission lines and uniformly inexpensive power rates, and by a federal power agency that positioned itself as a regional Chamber of Commerce. Since the Second World War, the Columbia River-centered Pacific Northwest has shaped its collective economic fortunes around exclusive regional access to BPA-provided Columbia River hydropower. But geographically distributed wealth did not end political conflict; private power companies, state governors, Native American tribes, and fish and wildlife agencies have had to be accommodated with distributions of BPA power and money. BPA-centered Columbia River management has through political conflict gradually expanded to serve wider interests, moving closer to the New Deal regionalist ideal. Yet in controversial decisions since 2000, Columbia River managers have chosen to risk wild salmon rather than breach federal Columbia River hydropower dams or allow Pacific Northwest power costs to escalate. They have done this because they have prioritized the most fundamental, and the most regional, Columbia River benefit of all: broadly shared inexpensive power. Understanding the opportunities and constraints of BPA-centered regional Columbia River management is essential in order to meet upcoming Columbia River policy challenges. / Adviser: Alexander B.

Search the library catalog for the location and call number. / Restoring oak habitats is an emerging conservation priority in Oregon's Willamette Valley. Both private and public landowners face multiple challenges to conservation and restoration of oak habitats, including a lack of knowledge about the potential tradeoffs and constraints for achieving multiple priorities on a given site. This study simulated 25 alternative oak habitat restoration scenarios to develop estimates of outcomes related to six different restoration priorities: costs, income potential, habitat value, scenic quality, fire hazard reduction potential, and time requirements. Model results indicated that initial land conditions strongly influence a landowner's ability to optimize among these different priorities. To assist landowners with decision-making, model estimates were organized into a digital decision matrix that communicates advantages and tradeoffs associated with each alternative scenario. In doing so, it aims to help landowners choose restoration goals that better meet their broader needs and objectives. / Committee in Charge: Dr. Bart Johnson, Chair; Dr. Robert Ribe

xv, 136 p. : ill. (some col.) / The Pacific Northwest of the United States has been tectonically and magmatically active with the accretion of the Farallon oceanic terrane "Siletzia" ∼50 Ma. The accretion of Siletzia terminated the flat-slab subduction of the Farallon slab and initiated the Cascadia subduction zone. In this dissertation, I focus on both the large-scale tectonic structures preserved seismically in the crust and upper mantle, and the small-scale, short-term aseismic processes on the plate interface. I measure the shear-wave splitting trends around eastern Oregon with a dataset of ∼200 seismometers from 2006-2008 to analyze the upper-mantle anisotropy. The delay times between splitted shear-waves range from 0.8 s to 2.7 s. In the High Lava Plains, the fast polarization direction is approximately E-W with average delay time ∼1.8 s. I infer that there must be significant active flow in a roughly E-W direction in the asthenosphere beneath this area. The splitting pattern is more variable and complicated in NE Oregon, where the crust and mantle lithosphere may be a significant contribution. In terms of the imaged seismic velocity structures, I infer that the Eocene sedimentary basins in south-central Washington lie above a magmatically underplated crust of extended Siletzia lithosphere. Siletzia thrusts under the pre-accretion forearc, and its southeast termination is especially strong and sharp southeast of the Klamath-Blue Mountains gravity lineament. Magmatic intrusion has increased upper crustal velocity as in the less active Washington Cascades, but the higher temperatures beneath the magmatically active Oregon Cascades have a dominating effect. To better understand the physical mechanism of slow slip events on the plate interface, I explore the scaling relationships of various source parameters collected mainly from subduction zones worldwide and also other tectonic environments. The source parameter scaling relationships of slow slip events highlight the similarities and differences between slow slip phenomena and earthquakes. These relationships hold implications for the degree of heterogeneity and fault healing characteristics. The recurrence statistics of northern Cascadia events behave weakly time predictable and moderately anti-slip predictable, which may indicate healing between events. This dissertation includes co-authored materials both previously published and submitted for publication. / Committee in charge: Eugene Humphreys, Chairperson; David Schmidt, Member; Ray Weldon, Member; James Isenberg, Outside Member

xii, 97 p. / Electricity generated from woody biomass material is generally considered renewable energy and has been considered carbon neutral. However, recent criticism from scientists argues that the greenhouse gas (GHG) emission profile of bioenergy is nuanced and the carbon neutral label is inappropriate. An initial carbon debt is created when a forest is harvested and combusted for bioenergy. Because forests re-grow over a period of years, life cycle analyses show that bioenergy generated from whole trees from forests may not reduce GHG emissions in the short term, as required to combat climate change. State renewable portfolio standards and federal laws and proposed legislation designed to incentivize renewable energy typically define eligible forms of biomass that qualify for these incentives. Most of these definitions are very broad and do not account for GHG emissions from bioenergy. Federal and state laws should incorporate life cycle analyses into definitions of eligible biomass so that these laws incentivize biomass electricity that reduces GHG emissions in the next several decades. / Committee in charge: Roberta Mann, Chairperson; Scott Bridgham, Member

xiii, 236 p. : ill. (some col.) / Over the past two decades, contemporary state-level watershed management burgeoned in the Pacific Northwest. This research offers a comparative analysis of contemporary state-level watershed management frameworks in the Pacific Northwest. The four case study areas consist of Idaho, Oregon, Washington, and Northern California. This study begins with a historical analysis of the greater watershed movement in natural resource management. Next, document analysis and key informant interviews are utilized to detail the watershed management framework of each state. Finally, this study explores a comparative analysis of each state framework. Results indicate that while the case study areas share many characteristics endemic to the bioregion, the watershed management framework of each state differs substantially. Key informant interviews indicate that these differences often reflect the unique sociopolitical climate of each state. Results additionally indicate the vital importance of stable state-derived funding for the establishment and resilience of watershed management organizations. / Committee in charge: Dr. Michael Hibbard, Chairperson; Dr. Richard Margerum, Member; Dr. Max Nielsen-Pincus, Member

This study is an analysis of a policy, The Indian Self-Determination Act (Public Law 93-638), and consists of a survey designed to examine the perceptions of selected Indian tribal leaders regarding the policy. The findings of the survey are reviewed and analyzed and the study is concluded with a consideration of the implications of the findings for social work. In general, the study is concerned with an aspect of the social policy process. A specific policy is addressed and a survey of perceptions of people effected by that policy was taken. The policy itself is an indication of a seemingly new attitude of the federal government toward Indian people. If this is so, this change is a significant departure from traditional attitudes and will affect the social service system as it relates to Indians as well as most other aspects of Indian life. Indian Self-Determination is a new term for Indian people.

Who are talented and gifted (TAG) students and how do we meet their unique needs in the elementary school setting? The body of literature clearly articulates the unique intellectual, social and emotional needs and characteristics of TAG students. Additionally, the literature supports the implementation of differentiated teaching strategies and affective curriculum to help meet these unique needs. This descriptive phenomenological study allowed gifted children, in fifth grade from a Pacific Northwest suburban elementary school, to share their lived experiences through reflective narratives and art. The data collected generated a central theme of Friends and general themes of Awareness, Feelings, Learning, and TAG Programming. Experiences that included friends were, by far, the most commonly shared; however, the participants also shared stories of wanting to be challenged and how they appreciated teachers who were more creative in curriculum delivery. Delisle (2012), Jessiman (2001) and Bergmark (2008) assert that in order to make progress in school reform and/or improvement we need to listen to our consumers and by consumers they are referring to our students. This study captures the gifted child's experience in elementary school and allows their voice to be heard.

Le litige concernant la frontière de l’Oregon, ou la question de l’Oregon, est le résultat des revendications britanniques et américaines pour la région du Pacifique Nord-Ouest de l’Amérique du Nord pendant la première moitié du XIXe siècle. Le Royaume-Uni et les États-Unis ont des aspirations territoriales et commerciales sur cette région. La région est pour les Britanniques une zone d’exploitation pour le commerce de la fourrure pour la Compagnie de la Baie d’Hudson, tandis que les Américains y voient une région peuplée de fermiers. Le différend sur l’Oregon est devenu important dans la diplomatie entre l’Empire britannique et la république américaine. / The Oregon boundary dispute, or the Oregon Question, arose as a result of competing British and American claims to the Pacific Northwest of North America in the first half of the 19th century. Both Great-Britain and the United States had territorial and commercial aspirations in the region. For the British, the area was a fur-trading division of the Hudson’s Bay Company, while for the Americans the region was to be settled by farmers. The Oregon dispute became an important diplomatic issue between the British Empire and the American Republic.

As Canada’s courts recognize and redefine the scope of Aboriginal title and rights in the country, alliances between Indigenous communities and environmental groups are playing an increasingly central role in the fight to stop fossil fuel infrastructure projects and address the global threats of climate change. Recognizing the importance of relationships between environmental non-governmental organizations (ENGO) and Indigenous peoples to environmental campaigns in Canada, and the need to include land-politics into the national conversation of reconciliation, this research project aims to investigate the role of reconciliation efforts in environmental campaigns in BC. Indigenous-ENGO relationships offer important opportunities to learn how actions and language of reconciliation are (or are not) being expressed in environmental campaigns, and to learn how ENGOs are approaching their work with Indigenous communities in an era of reconciliation. Using two campaigns as my case studies I explore these topics by interviewing ENGO staff and Indigenous peoples working collaboratively on the Site C Dam campaign in the Peace River region of Treaty 8 in northeast BC, and the Pacific Northwest liquid natural gas (LNG) terminal project in the Skeena River watershed region in the traditional territories of the Tsimshian, Gitxsan, and Wet’suwet’en nations of northwest BC. Informed by Indigenous and anti-colonial research methodologies, a principle of relational accountability is used to center relationships with land as a foundation for reconciliation, and for recommendations on how Indigenous-ENGO relationships can be improved. / Graduate
