Engagement For Life's Sake: Reflections On Partnering And Partnership With Rural Tribal Nations☆, Chelsea Schelly, Valoree Gagnon, Kathleen Brosemer, Kristin Arola
Engagement For Life's Sake: Reflections On Partnering And Partnership With Rural Tribal Nations☆, Chelsea Schelly, Valoree Gagnon, Kathleen Brosemer, Kristin Arola
Michigan Tech Publications, Part 2
In this paper, we reflect on our collective experiences engaging with Anishinaabe Tribal Nations in the Great Lakes region to support Tribal sovereignty in decision-making for food, energy, and water (FEW) systems. In these diverse experiences, we find common lessons. The first set of lessons contributes new empirical knowledge regarding the challenges and opportunities that rural Great Lakes Tribal Nations navigate for enacting sovereignty in decision-making. Our experiences illustrate that while Tribal Nations benefit from a broad and deep commitment to sovereignty and many cultural strengths, they are often challenged by shortages in administrative capacity; technical support; and embeddedness in …

Scientific study of issues at the nexus of food–energy–water systems (FEWS) requires grappling with multifaceted, “wicked” problems. FEWS involve interactions occurring directly and indirectly across complex and overlapping spatial and temporal scales; they are also imbued with diverse and sometimes conflicting meanings for the human and more-than-human beings that live within them. In this paper, we consider the role of language in the dynamics of boundary work, recognizing that the language often used in stakeholder and community engagement intended to address FEWS science and decision-making constructs boundaries and limits diverse and inclusive participation. In contrast, some language systems provide opportunities …
The Decline Of Lake Superior's Woodland Caribou: A Historical Gis Analysis, Jordan W. Kelley
The Decline Of Lake Superior's Woodland Caribou: A Historical Gis Analysis, Jordan W. Kelley
Dissertations, Master's Theses and Master's Reports
Lake Superior’s woodland caribou have been declining since the early 1800s. This thesis asks: why? We hypothesize that as settlers expanded into the region, industrial development in woodland caribou habitat reduced woodland caribou persistence. Using an Historical Geospatial Information System (HGIS) analysis, we find that historical mining and railroad infrastructure are associated with woodland caribou extirpation, while wetlands and protected areas are associated with caribou persistence. We also conducted a stakeholder synthesis of the region to help understand diverse perspectives within and between advocacy coalitions that take different positions on the most effective caribou restoration policies. Beliefs on recovery options …

Insufficient funding is a major impediment to conservation efforts around the world. In the United States, a decline in hunting participation threatens sustainability of the “user-pay, public benefit” model that has supported wildlife conservation for nearly 100 years, forcing wildlife management agencies to contemplate alternative funding strategies. We investigated support for potential funding options among diverse college students, a rapidly expanding and politically active voting bloc with a potentially powerful influence on the future of conservation. From 2018 to 2020, we surveyed 17,203 undergraduate students at public universities across 22 states. Students preferred innovative approaches to conservation funding, with 72% …

Higher spatial and temporal resolutions of remote sensing data are likely to be useful for ecological monitoring efforts. There are many different treatment approaches for the introduced European genotype of Phragmites australis, and adaptive management principles are being integrated in at least some long-term monitoring efforts. In this paper, we investigated how natural color and a smaller set of near-infrared (NIR) images collected with low-cost uncrewed aerial vehicles (UAVs) could help quantify the aboveground effects of management efforts at 20 sites enrolled in the Phragmites Adaptive Management Framework (PAMF) spanning the coastal Laurentian Great Lakes region. We used object-based image …

Although renewable energy holds great promise in mitigating climate change, there are socioeconomic and ecological tradeoffs related to each form of renewable energy. Forest‐related bioenergy is especially controversial, because tree plantations often replace land that could be used to grow food crops and can have negative impacts on biodiversity. In this study, we examined public perceptions and ecosystem service tradeoffs between the provisioning services associated with cover types associated with bioenergy crop (feedstock) production and forest habitat‐related supporting services for birds, which themselves provide cultural and regulating services. We combined a social survey‐based assessment of local values and perceptions with …

Griffith, Virginia H. Dale, Chelsea Schelly, Anna Maria Marshall, Valoree Gagnon, Weston M. Eaton, Kristin Floress
Michigan Tech Publications
Community and stakeholder engagement is increasingly recognized as essential to science at the nexus of food, energy, and water systems (FEWS) to address complex issues surrounding food and energy production and water provision for society. Yet no comprehensive framework exists for supporting best practices in community and stakeholder engagement for FEWS. A review and meta‐synthesis were undertaken of a broad range of existing models, frameworks, and toolkits for community and stakeholder engagement. A framework is proposed that comprises situational awareness of the FEWS place or problem, creation of a suitable culture for engagement, focus on power‐sharing in the engagement process, …
Impacts Of Forest Tax Programs On Property Tax Rates In Michigan's Upper Peninsula And Northern Wisconsin, Elsa Schwartz
Impacts Of Forest Tax Programs On Property Tax Rates In Michigan's Upper Peninsula And Northern Wisconsin, Elsa Schwartz
Dissertations, Master's Theses and Master's Reports
Forest tax programs offer reduced property taxes to private forest owners as incentive to sustainably manage their forests and to encourage the provision of ecosystem services. They also protect forests from conversion to other land uses and ensure the viable supply of timber for forest products industries. Despite the benefits that these programs provide, they can negatively impact local municipalities by reducing the property tax base, which can then cause local governments to increase tax rates for non-preferential properties in order to maintain revenue needed to run their services. This shifts the tax burden from participating properties to nonparticipating properties. …
Training Future Agriculture Professionals In Landowner–Tenant Conservation Decision-Making, Andrea Basche, Angela Carter
Training Future Agriculture Professionals In Landowner–Tenant Conservation Decision-Making, Andrea Basche, Angela Carter
Michigan Tech Publications
The landowner–tenant relationship is important to the implementation of conservation on agricultural lands. Women own or co-own a significant portion of U.S. farmland yet are underrepresented in conservation research. The next generation of agriculture professionals can benefit from first-hand experience in assisting women landowners and their tenants in navigating the complexities of conservation decision-making. This article analyzes undergraduate student perceptions of landowner–tenant relationships in conservation management through their engagement in case studies with women landowner–tenant pairs in the Western Corn Belt. Student groups were asked to complete a management improvement plan that both incorporated the agronomic and conservation goals discussed …

Enrollment Decision-Making By Students In Forestry And Related Natural Resource Degree Programmes Globally, T. L. Bal, M. D. Rouleau, T. L. Sharik, A. M. Wellstead
Michigan Tech Publications
A survey of 396 undergraduate and graduate students from 51 countries on 5 continents currently enrolled in Forestry or Related Natural Resource (FRNR) degree programmes was conducted of attendees to the International Union of Forest Research Organizations' (IUFRO) conference in Salt Lake City, Utah, 2014. These perspectives come from some of the most active students in their respective fields. We explored the motivating reasons for enrolling in their current FRNR programme, and conversely why they may have been hesitant to do so. Results indicate that enjoyment of nature was the most important factor on average driving the decision to enroll, …
What Is An Endangered Species?: Judgments About Acceptable Risk, Thomas Offer-Westort, Adam Feltz, Jeremy T. Bruskotter, John A. Vucetich
What Is An Endangered Species?: Judgments About Acceptable Risk, Thomas Offer-Westort, Adam Feltz, Jeremy T. Bruskotter, John A. Vucetich
Michigan Tech Publications
Judgments about acceptable risk in the context of policy may be influenced by law makers, policy makers, experts and the general public. While significant effort has been made to understand public attitudes on acceptable risk of environmental pollution, little is known about such attitudes in the context of species' endangerment. We present survey results on these attitudes in the context of United States' legal-political apparatus intended to mitigate species endangerment. The results suggest that the general public exhibit lower tolerance for risk than policy makers and experts. Results also suggest that attitudes about acceptable risk for species endangerment are importantly …
‘Coronated’ Consumption In The Viral Market, Soonkwan Hong
‘Coronated’ Consumption In The Viral Market, Soonkwan Hong
Michigan Tech Publications
The universal exposure to the virus has disrupted institutions, redefined values, and reshaped systems, including the market. Idling, uncertainty, and liquidity encapsulate the ever-precarious individual lives and the reflexive socio-politico-cultural changes. These conditions and consequences nonetheless create paradoxical opportunities in the viral market. The new meaning of connectivity that promotes high-viscosity relationships and high-visibility identities will transform the market to better acknowledge and support humans and the new sociality.
Copper-Rich “Halo” Off Lake Superior's Keweenaw Peninsula And How Mass Mill Tailings Dispersed Onto Tribal Lands, W. Charles Kerfoot, Noel Urban, Jaebong Jeong, Carol Maclennan, Sophia Ford
Copper-Rich “Halo” Off Lake Superior's Keweenaw Peninsula And How Mass Mill Tailings Dispersed Onto Tribal Lands, W. Charles Kerfoot, Noel Urban, Jaebong Jeong, Carol Maclennan, Sophia Ford
Michigan Tech Publications
Over a century ago, shoreline copper mills sluiced more than 64 million metric tonnes of tailings into Lake Superior, creating a “halo” around the Keweenaw Peninsula with a buried copper peak. Here we examine how tailings from one of the smaller mills (Mass Mill, 1902–1919) spread as a dual pulse across southern Keweenaw Bay and onto tribal L'Anse Indian Reservation lands. The fine (“slime clay”) fraction dispersed early and widely, whereas the coarse fraction (stamp sands) moved more slowly southward as a black sand beach deposit, leaving scattered residual patches. Beach stamp sands followed the path of sand eroding from …
Livestock-Wildlife Dynamics And Subsequent Human Responses In Marginalized Communities Within Mexico’S Nationally Protected Areas, Deanna Seil
Dissertations, Master's Theses and Master's Reports
Entering the planet’s sixth mass-extinction, monitoring biodiversity and the factors which affect it is of the utmost importance. This study on the interaction of humans and their livestock with wildlife, and the impact of this interaction on wildlife conservation, took place in Santiago Coatepec, located within the Tehuacán-Cuicatlán Biosphere Reserve in Mexico. Wildlife interactions with livestock may depend upon species, season, ecological characteristics of the area, and livestock management practices. Using camera traps, field data, and interview data, I quantified livestock impact on wildlife behavior and community beliefs. Over two years, camera traps at 18 stations recorded 709 wildlife videos …
The Influence Of Landforms And Sampling Approaches On Riparian Buffer Area And Complexity, Houjun Ding
The Influence Of Landforms And Sampling Approaches On Riparian Buffer Area And Complexity, Houjun Ding
Dissertations, Master's Theses and Master's Reports
A riparian area is a zone of interaction between aquatic and terrestrial ecosystems. Delineating accurate riparian management zones (RMZs), often utilized in Best Management Practices (BMPs) for wetlands and stream protection, is important. The Riparian Buffer Delineation Model (RBDM) has been used extensively for accurate RMZs delineation. Utilizing the validated RBDM generates additional questions about riparian area form and function, which will ideally lead to an improved understanding of the ecological process within these zones. This study aims to determine how geomorphic landforms and their associated landscape characteristics influence riparian areas in terms of shape and complexity, whether sampling methods …
Perceptions Of Forest Change In The Governmental Region Of Kaffrine, Senegal, Rhiley E. Allbee
Perceptions Of Forest Change In The Governmental Region Of Kaffrine, Senegal, Rhiley E. Allbee
Dissertations, Master's Theses and Master's Reports
Sénégal is a semi-arid West African country with a diverse ethnic makeup and a rapidly growing population that is largely rural, predominantly employed within the agricultural sector, and heavily reliant on the harvesting of forest products within state owned forests where populations have usufruct rights. The country experienced significant changes in land cover throughout the 20th century due to a series of major droughts and large expansions in agriculture. These changes were partially concentrated throughout the region of Kaffrine, where the wooded savannas of the early 20th century were systematically replaced by agriculture and converted to a shrub …

Restoring And Sustaining Smallholder Kappaphycus Alvarezii Farming Post-Typhoon Haiyan/Yolanda In Molocaboc, Central Philippines, David C. Fenlon
Dissertations, Master's Theses and Master's Reports
The farming of marine seaweed has the potential to provide both nutritional and financial resources to developing communities such as the Molocaboc Islands in the Philippines. To foster this mariculture development approximately $1,000 USD in grant funds received from the US-Philippines Society was used to purchase materials needed to replace seaweed production infrastructure lost to Typhoon Haiyan (known as Super Typhoon Yolanda in the Philippines). The goal was to restore and expand smallholder farming of the seaweed Kappaphycus alvarezii (locally known as ‘guso’ in the Visayan dialect) in the Molocaboc Islands, thereby increasing harvest yields as compared to those …
Characterization Of Ecological Water Stress In The U.S. Great Lakes Region Using A Geospatial Modeling Approach, Sara Alian
Dissertations, Master's Theses and Master's Reports
Anthropocentric water resources management affects aquatic habitats by changing streamflow regime. Understanding the impacts of water withdrawal from different sources and consumption by various economic sectors at different spatial and temporal scales is key to characterizing ecologically harmful streamflow disturbances. To this end, we developed a generic, integrative framework to characterize catchment scale water stress at annual and monthly time scales. The framework accounts for spatially cumulative consumptive and non-consumptive use impacts and associated changes in flow due to depletion and return flow along the stream network. Application of the framework to the U.S. Great Lakes Region indicates that a …

Critical Review Of The Millennium Project In Nepal, Ashma Vaidya, Audrey L. Mayer
Critical Review Of The Millennium Project In Nepal, Ashma Vaidya, Audrey L. Mayer
College of Forest Resources and Environmental Science Publications
“Our Common Future” harmonized development policies around a new sustainable development (SD) paradigm, and experts also emphasize the importance of a democratic and equitable approach to define and achieve sustainable development. However, SD targets and indicators are often defined by a suite of experts or a few stakeholder groups, far removed from on-the-ground conditions. The most common expert-led development framework, the United Nations’ Millennium Development Goals (MDGs), promoted one set of targets and indicators for all developing countries. While progress towards these targets was routinely reported at the national scale, these targets may not reflect context-specific sustainable development. We evaluated …
Assisted Tree Migration In North America: Policy Legacies, Enhanced Forest Policy Integration, And Climate Change Adaptation, Adam Wellstead, Michael Howlett
Assisted Tree Migration In North America: Policy Legacies, Enhanced Forest Policy Integration, And Climate Change Adaptation, Adam Wellstead, Michael Howlett
Department of Social Sciences Publications
The weight of much expert forest management opinion is that issues such as climate change can be effectively addressed only if forest policy-making moves from a purely sectoral focus and undergoes a shift to a more integrated multi-issue, multi-sector policy-making process. This is because credible adaptation policies in the sector require greatly enhanced multi-sectoral policy integration if they are to succeed. But this requirement may be beyond the capacity of many countries to deliver. This article explores the integration challenges faced by forest policy-making in Canada and the United States and uses the case of Assisted Tree Migration (ATM) to …
Failure To Communicate: Inefficiencies In Voluntary Incentive Programs For Private Forest Owners In Michigan, Mark. D. Rouleau, Jennifer F. Lind-Riehl, Miranda N. Smith, Audrey L. Mayer
Failure To Communicate: Inefficiencies In Voluntary Incentive Programs For Private Forest Owners In Michigan, Mark. D. Rouleau, Jennifer F. Lind-Riehl, Miranda N. Smith, Audrey L. Mayer
College of Forest Resources and Environmental Science Publications
Coordinating forest management across thousands of nonindustrial private forest (NIPF) owners is a difficult yet necessary task for state land management agencies. Voluntary Incentive Programs (VIPs) can coordinate the decentralized activities of these owners in return for services or financial incentives. However, many VIPs typically have low enrollment. Our study investigates the implementation of VIPs to increase forest management coordination among NIPFs in Michigan. We present findings from 20 semi-structured interviews with leaders of state and local land management organizations, and government officials at state natural resource agencies, and contrast their answers with those recorded from 37 interviews of NIPF …
Using An Obcd Approach And Landsat Tm Data To Detect Harvesting On Nonindustrial Private Property In Upper Michigan, Riccardo Tortini, Audrey L. Mayer, Pieralberto Maianti
Using An Obcd Approach And Landsat Tm Data To Detect Harvesting On Nonindustrial Private Property In Upper Michigan, Riccardo Tortini, Audrey L. Mayer, Pieralberto Maianti
College of Forest Resources and Environmental Science Publications
Forest dynamics influence climate, biodiversity, and livelihoods at multiple scales, yet current resource policy addressing these dynamics is ineffective without reliable land use land cover change data. The collective impact of harvest decisions by many small forest owners can be substantial at the landscape scale, yet monitoring harvests and regrowth in these forests is challenging. Remote sensing is an obvious route to detect and monitor small-scale land use dynamics over large areas. Using an annual series of Landsat-5 Thematic Mapper (TM) images and a GIS shapefile of property boundaries, we identified units where harvests occurred from 2005 to 2011 using …

Teaching Interdisciplinary Sustainability Science Teamwork Skills To Graduate Students Using In-Person And Web-Based Interactions, Jessie Knowlton, Kathleen E. Halvorsen, Robert Handler, Michael O'Rourke
Michigan Tech Publications
Interdisciplinary sustainability science teamwork skills are essential for addressing the world’s most pressing and complex sustainability problems, which inherently have social, natural, and engineering science dimensions. Further, because sustainability science problems exist at global scales, interdisciplinary science teams will need to consist of international members who communicate and work together effectively. Students trained in international interdisciplinary science skills will be able to hit the ground running when they obtain jobs requiring them to tackle sustainability problems. While many universities now have sustainability science programs, few offer courses that are interdisciplinary and international in scope. In the fall semester of 2013, …
Fishery Co-Management Opportunities Between Tribal And State Agencies: Conflict To Collaboration, J. Marty Holtgren
Fishery Co-Management Opportunities Between Tribal And State Agencies: Conflict To Collaboration, J. Marty Holtgren
Dissertations, Master's Theses and Master's Reports - Open
Over the past 40 years global recognition has occurred for indigenous groups to be represented and have input in how natural resources are managed. This has largely occurred because of how management decisions have consequences to indigenous groups that reach beyond natural resource issues but into cultural, spiritual, social and political elements including sovereignty, legitimacy, justice, equity and empowerment and using indigenous paradigms to meet indigenous needs. In the United States numerous legal agreements have been reached that pair state and tribal agencies into co-management. This project concerns a recent co-management agreement between the State of Michigan and five Native …
Development And Validation Of The Anterior Cruciate Ligament Injury-Risk-Estimation Quiz (Acl-Iq), Erich J. Petushek
Development And Validation Of The Anterior Cruciate Ligament Injury-Risk-Estimation Quiz (Acl-Iq), Erich J. Petushek
Dissertations, Master's Theses and Master's Reports - Open
Over 2 million Anterior Cruciate Ligament (ACL) injuries occur annually worldwide resulting in considerable economic and health burdens (e.g., suffering, surgery, loss of function, risk for re-injury, and osteoarthritis). Current screening methods are effective but they generally rely on expensive and time-consuming biomechanical movement analysis, and thus are impractical solutions. In this dissertation, I report on a series of studies that begins to investigate one potentially efficient alternative to biomechanical screening, namely skilled observational risk assessment (e.g., having experts estimate risk based on observations of athletes movements). Specifically, in Study 1 I discovered that ACL injury risk can be accurately …
Application Of An Imputation Method For Geospatial Inventory Of Forest Structural Attributes Across Multiple Spatial Scales In The Lake States, U.S.A., Ram K. Deo
Dissertations, Master's Theses and Master's Reports - Open
Credible spatial information characterizing the structure and site quality of forests is critical to sustainable forest management and planning, especially given the increasing demands and threats to forest products and services. Forest managers and planners are required to evaluate forest conditions over a broad range of scales, contingent on operational or reporting requirements. Traditionally, forest inventory estimates are generated via a design-based approach that involves generalizing sample plot measurements to characterize an unknown population across a larger area of interest. However, field plot measurements are costly and as a consequence spatial coverage is limited. Remote sensing technologies have shown remarkable …

Beyond Roots Alone: Novel Methodologies For Analyzing Complex Soil And Minirhizotron Imagery Using Image Processing And Gis Tools, Justina A. Silva
Dissertations, Master's Theses and Master's Reports - Open
Quantifying belowground dynamics is critical to our understanding of plant and ecosystem function and belowground carbon cycling, yet currently available tools for complex belowground image analyses are insufficient. We introduce novel techniques combining digital image processing tools and geographic information systems (GIS) analysis to permit semi-automated analysis of complex root and soil dynamics. We illustrate methodologies with imagery from microcosms, minirhizotrons, and a rhizotron, in upland and peatland soils. We provide guidelines for correct image capture, a method that automatically stitches together numerous minirhizotron images into one seamless image, and image analysis using image segmentation and classification in SPRING or …

I utilized state the art remote sensing and GIS (Geographical Information System) techniques to study large scale biological, physical and ecological processes of coastal, nearshore, and offshore waters of Lake Michigan and Lake Superior. These processes ranged from chlorophyll a and primary production time series analysies in Lake Michigan to coastal stamp sand threats on Buffalo Reef in Lake Superior. I used SeaWiFS (Sea-viewing Wide Field-of-view Sensor) satellite imagery to trace various biological, chemical and optical water properties of Lake Michigan during the past decade and to investigate the collapse of early spring primary production. Using spatial analysis techniques, I …
Peer Influence Of Non-Industrial Private Forest Owners In The Western Upper Peninsula Of Michigan, Jillian R. Schubert, Audrey L. Mayer
Peer Influence Of Non-Industrial Private Forest Owners In The Western Upper Peninsula Of Michigan, Jillian R. Schubert, Audrey L. Mayer
College of Forest Resources and Environmental Science Publications
Understanding how non-industrial private forest (NIPF) owners gain and share information regarding the management of their property is very important to policy makers, yet our knowledge regarding how and to what degree this information flows over privately owned landscapes is limited. The work described here seeks to address this shortfall. Widely administered surveys with close-ended questions may not adequately capture this information flow within NIPF owner communities. This study used open-ended questions in interviews of clusters of NIPF owners to determine whether and to what extent owners influence each other directly (through conversations or referrals to sources of advice) or …
