Collaborative Problem-Solving For Environmental Justice, Sophie C. Wolfram

Graduate Student Theses, Dissertations, & Professional Papers

An extensive body of environmental justice literature has demonstrated repeatedly what impacted communities have long known from experience, that environmental pollution including groundwater threats, diesel particulate matter, toxic releases, pesticide use, and hazardous waste sites, disproportionately burdens people of color and low-income communities. The environmental justice movement seeks to bring about equal protection of all people from environmental hazards, including equal enforcement of environmental laws and regulations. Advocacy within the movement has frequently adopted oppositional framings with respect to the state; however, collaborative approaches to environmental justice problem-solving have become more common, especially as states increasingly recognize environmental justice in …

Does Timing Of Herbicide Use Influence Rates Of Germination Or Seedling Biomass Of Native Plants Used For Restoration?, Christine Mcmanamen

Graduate Student Theses, Dissertations, & Professional Papers

Invasive plants can negatively impact native grasslands by changing their species composition, productivity, and function. Managers commonly use herbicides as a control method; however, this practice can lead to secondary invasion by other non-native invasive plants, unless measures are taken to promote natives. Because of this, managers often seed native plants after spraying herbicides. There is evidence, however, that chemical control of invasive plants may reduce the effectiveness of subsequent seed-addition treatments, but there is currently little quantitative information on optimal timing between spraying and seeding or on variation in herbicide sensitivity among native plants commonly used in seed mixes. …

Poison In Pink, Sydney V. Cook

Graduate Student Theses, Dissertations, & Professional Papers

Humans slather, spray, mist, and cleanse their bodies with personal care products like lotion, hairspray, cologne, and shampoo every day. Our cupboards are stocked full of them, but few of us understand what is in those jars and bottles. We trust that if it’s on the shelf at the store, it’s safe. However, this is not always the case, and many personal care products contain chemicals that are harmful to human and environmental health.

My multi-disciplinary Environmental Studies thesis project combines evidenced-based research, interviews, nonfiction narrative, and science communication to create part of a book manuscript intended to educate general …

Limited Evidence For Co2-Related Growth Enhancement In Northern Rocky Mountain Pinus Contorta Populations: Trends In Growth And Intrinsic Water-Use Efficiency Across Climate Gradients, Charlotte C. Reed

Graduate Student Theses, Dissertations, & Professional Papers

Forests sequester large amounts of carbon annually; however, the degree to which enhanced forest productivity is due to more conducive climate or CO₂ fertilization remains uncertain. Increasing atmospheric CO₂ may enhance photosynthesis and/or decrease stomatal conductance thereby enhancing intrinsic water use efficiency (iWUE). While increasing iWUE has been observed in most trees globally, this increase does not necessarily translate into greater growth. This study aims to evaluate whether responses of radial growth and iWUE to increasing CO₂ vary across climatic gradients. To investigate interactions between climate and CO₂ and their impacts on tree physiology and growth, …

Carrying The Seeds: Adaptations And Transitions Of Hmong American Food Producers In Missoula County, Montana, Rachel Cramer

Graduate Student Theses, Dissertations, & Professional Papers

Forty years after the initial resettlement of Hmong refugees in Missoula County, Montana, the Hmong American community has undergone significant agricultural and cultural adaptations. Today, there are about 200 Hmong Americans in the county, less than 2% of the population (US Census Bureau 2010), but they make up around 40% of the farmers’ market produce vendors. The thesis demonstrates that, while agriculture has played a central role in helping Hmong refugees adapt, its role is becoming more symbolic as the second generation develops an identity less connected to growing and selling food. Through a qualitative research approach using 19 in-depth …

A Comparison Of Course Quality Surveiy Results From Students On Gender Balanced And Gender Imbalanced Field Courses At Nols, Alexandra M. Alway

Graduate Student Theses, Dissertations, & Professional Papers

There is an extensive database of literature about diversity in outdoor Environmental Education and any of the studies focus on NOLS specifically. Several studies have investigated the impact of course composition in terms of gender as well as socioeconomic diversity; however, the research studies about course composition and gender were limited to differences between single gender and coed groups. The role of gender ratios on coed groups has not been widely researched. This study was designed to fill this gap in the research literature. Using course quality survey data, results showed that the student responses were significantly different between gender …

Acid mine drainage (AMD), characterized by low pH and abundant heavy metals, is a widespread problem affecting water quality and fish habitat in Montana. Montana’s upper Blackfoot River exhibits impaired water quality from historic mining that has significantly degraded aquatic habitat and reduced fish and invertebrate abundance in impacted streams. The goal of this study is to investigate the direct and indirect effects of mine-related heavy metals contamination on aquatic ecosystems by examining changes in aquatic community composition, bioaccumulation, and toxicity risk of heavy metals along a contamination gradient in the upper Blackfoot River. Three primary research questions were addressed …

Close Call With Nonexistence: A Memoir, Jeff Gailus

Graduate Student Theses, Dissertations, & Professional Papers

Fred Eduard Gailus was born on April 26, 1944, in Memelland, a place that no longer exists. It was a tiny sliver of Germandom on the far eastern edge of Hitler’s outsized German Reich. When the Soviet Red Army swept through on their way to Berlin, to end World War Two and the reign of terror perpetrated by the German people, the homeland of my father’s ancestors was wiped off the map forever. Thanks to the courage and tenacity of his mother, Fred survived the largest forced migration in human history to marry young and raise a family of four …

40 Trees: The Quest To Save Whitebark Pine On The Flathead Indian Reservation, Andrew S. Graham

Graduate Student Theses, Dissertations, & Professional Papers

When it comes to managing natural resources in the face of global climate change, sometimes localized action is best. Rick Everett spent a lot of time in western forests - first as a ski patroller and logger and then as an ecologist - before landing as a professor at a tribal community college on the Flathead Indian Reservation. Now he faces a challenging new question: How do you save a tree species that is ecologically valuable to the forest and culturally valuable to Native American tribes, but is being pushed toward extinction by forces varied, deadly and driven by climate …

Performance Measures Of Road Crossing Structures From Relative Movement Rates Of Large Mammals, Adam Andis

Graduate Student Theses, Dissertations, & Professional Papers

In recent decades, there has been an increase of engineering projects that seek to mitigate the barrier effect roads impose on wildlife by installing wildlife crossing structures that promote permeability of the road corridor. The 41 fish and wildlife crossing structures installed along a 90km stretch of US Highway 93 on the Flathead Indian Reservation in western Montana, represent one of the most extensive of such projects in North America. As mitigation efforts are increasingly considered and implemented in road construction projects, the need to assess these structures’ effectiveness grows. This study is the first to compare observations of animal …

Baseline Study Of Recovering Headwater Streams In The Sapphire Mountains, Western Montana, Morgan Vinyard

Graduate Student Theses, Dissertations, & Professional Papers

Many riparian areas in the western United States have been degraded by grazing and logging. In the year 2000, the Montana Department of Environmental Quality (DEQ) re-initiated an effort to identify and characterize reference streams, or least impacted streams in each region of the state. In Montana’s Bitterroot Valley, most streams have been impacted by grazing, irrigation, and timber production. The Montana DEQ has not been able to identify reference streams in the Sapphire Mountains on the east side of this valley. MPG Ranch, located on the west-facing slopes of the Sapphire Mountains and purchased in 2009 by a conservation-minded …

Assessing Household Drinking Water Needs: Reaching Many One Water Filter At A Time In Los Robles, Nicaragua, Erinkate E. Springer

Graduate Student Theses, Dissertations, & Professional Papers

Water quality and water scarcity have dominated international health and environmental management initiatives for decades because of the devastating impacts poor water quality has on child mortality and general public well-being, particularly in developing countries. Non-profit organizations, private utilities, and government agencies have invested significant financial resources and time to increase access to improved water sources in low-income countries. However, the sustainability of water improvement project benefits have been disappointing due to a lack of community and household capacity to operate and maintain introduced water systems. This paper evaluates a community/household based water improvement project introduced by a small non-governmental …

Adaptation On A Budget: How Vietnamese Innovators Are Trying To Design Their Way Out Of Climate Change, Shanti R. Johnson

Graduate Student Theses, Dissertations, & Professional Papers

In the rapidly developing Mekong Delta of Vietnam, young innovators are facing a challenge far greater than simply trying to catch up with the wealthier world. In a growing trend, the next generation of Vietnamese is acting under a common understanding: climate change is real, it’s here and the time to respond is growing short.

For over a decade, Southern Vietnam has consistently been ranked by international organizations like the Intergovernmental Panel on Climate Change as one of the most vulnerable places in the world to the impacts of climate change. That vulnerability is heightened by the fact that the …

Crossing The Line: Navigating A Polluted Transboundary Watershed, Celia T. Tobin

Graduate Student Theses, Dissertations, & Professional Papers

Montana’s Lake Koocanusa sits at the end of a river system that drains Canada’s most productive coal country. Today, the waters of the massive lake contain a mineral called selenium, a poorly understood byproduct of mine waste. This summer, the U.S. federal government will be in a position to declare that the selenium in the lake puts Canada in violation of its international treaty with the U.S. The Montana government, however, is preparing to argue otherwise through its own water analysis. The disagreement has U.S. ecologists frustrated with the state’s position, saying they won’t practice science that is slave to …

The Sacrificial Ram, Charles Ebbers

Graduate Student Theses, Dissertations, & Professional Papers

Every January and February, Montana and other western states auction tags to hunt big horn sheep, moose, mountain goats, bears and other big game species to the highest bidder, at a series of hunting shows in Nevada. Some states call them “governor’s tags,” while others like Montana call them auction tags.

The purpose of the auctions is to raise funds for state conservation programs meant to keep wildlife populations healthy. In Montana, the funds raised are species specific, meaning that the proceeds from a bighorn sheep tag must be used to help bighorn sheep. Yet, the revenue from these tags …

The Way Around: Walking Into Revolution, Nicholas T. Triolo

Graduate Student Theses, Dissertations, & Professional Papers

The Way Around: Walking into Revolution

Chairperson: Phil Condon

The Way Around investigates revolution through personal accounts of pilgrimage, ecopsychology, and activism. For ten years (2006-2016), I engaged in various forms of circular travel across the world to understand the true shape of revolution—its etymology, its use throughout history, and if revolution might be some universal inertia that drives us all forward.

The journey begins in 2006, where I travel around the world for a year. I weave together discoveries of place and planet with a 500-year historical account of human circumnavigation. Returning to Portland, Oregon, I’m introduced to …

The Next Billion: Lessons In Off-Grid Electricity Development From The Global South, Peter Mcdonough

Graduate Student Theses, Dissertations, & Professional Papers

Today about a third of the world’s population has no access to electricity, and another third has only limited access. Driven by the push for development on one hand and the reality of climate change on the other, a combination of for-profit companies, NGOs, missions, and aid organizations is looking for the silver bullet to sustainable electricity development. In order to understand the challenges facing off-grid electricity projects I used recent literature in the form of peer-reviewed journals, agency reports, news articles, and technical documents; stakeholder interviews; and on-site observations in selected case studies in Nepal, India, and Tanzania.

73,401 Hexagons: A Geodiversity Gap Analysis Of The Crown Of The Continent Ecosystem, Robina A. Moyer

Graduate Student Theses, Dissertations, & Professional Papers

The Crown of the Continent Initiative (CCI) is a transboundary collaborative of conservation groups who work to further conservation goals throughout the Crown of the Continent Ecosystem, located in Northwestern Montana and southern British Columbia and Alberta. CCI and their member groups are interested in using geodiversity as a conservation measure in the Crown Ecosystem. First suggested in 1988 (Hunter et al.), geodiversity, or land facets, are typically a combination of abiotic features used as surrogates for the overlying biotic features. Conservation planning often employs an approach of coarse and fine filters, gap analysis, and systematic reserve design to identify …

A Critical Examination Of Private Conservation Areas On Campesino Community Lands In Peru, Megan Barnhart

Graduate Student Theses, Dissertations, & Professional Papers

Community-owned private reserves are emerging around the world as an alternative to government-run resource management and as a way to more directly involve citizens as stewards of their local natural resources. Despite their recent proliferation globally, voluntary efforts by communities to include their land in protected area systems, and the motivations and expectations of their legal recognition remain largely unknown. This thesis examines community-owned private conservation areas in Northern Peru locally known as Áreas de Conservación Privadas (ACPs) which are voluntary and legally recognized by the Peruvian State. The study investigates the rationales and outcomes of the application of ACPs …

Instituting Collaborative Conservation In Federal Land Management: The Blm's Resource Advisory Councils As An Example, Benjamin D. Donatelle

Graduate Student Theses, Dissertations, & Professional Papers

Collaborative Conservation is one type of Environmental Conflict Resolution (ECR) that, since the 1970’s, has proliferated throughout public land and natural resource management, especially in the Western United States. As the notion of collaboration has risen in the collective consciousness of public land management professionals, various efforts to capitalize on its use have been instituted through regulatory reforms and legislation. For twenty years the Resource Advisory Councils have fulfilled their regulatory responsibilities and exemplify policy mandated collaborative consensus-building process, yet little research has been conducted to understand what contributes to their effectiveness. This study investigates the effect of instituting or …

Rural Food Procurement Strategies And Attitudes Towards Food Sourcing: A Case Study Of Boulder Town, Utah, Jane R. Philips

Graduate Student Theses, Dissertations, & Professional Papers

Today, while the United States continues to boast one of the highest standards of living in the world, rural communities suffer from an inability to acquire sufficient healthy food. Rural food systems have undergone a substantial transition over the last 50 years causing previously agricultural regions to now depend heavily on outside food sources. It should not be so hard to consume food produced within these rural communities, yet it is.

Researchers relying on secondary data analysis from national scale databases may identify rural areas as “low food access,” however, gaps in available records inhibit the development of a full …

The Historical And Cultural Landscape Of The Missoula Valley During The 19th And 20th Centuries, Mary Bobbitt

Graduate Student Theses, Dissertations, & Professional Papers

Archaeological case studies can be used as microcosms for understanding questions related to landscape transformations and climate change throughout the arid American West.
