On Forests, Witness Trees, and Bears
This dissertation is about Forests, their loss and the grieving that arises from their loss. The loss of ancient and old-growth forests by way of clearcutting and or anthropogenically driven disturbances, including climate change, presents the quandary of loss of both biological and cultural diversity. Following Umeek’s/E. Richard Atleo’s term, I suggest that “dis-ease” in the dominant relationship to forests in parts of the Western world significantly rests within inherited cultural and political pasts at play in the present, carried in much of the language and lifeways of modern Anglophone societies today. I do so by a critical topographical exploration of thematic patterns that go back to the Epic of Gilgamesh, the oldest written account of deforestation in the history of Western civilization. I offer at the center of my inquiry a collection of witness trees as North American case studies. Each tree is a witness object, a station from which I confront and explore social-ecological grief as it has accumulated over time from English colonization, with one focusing on Indigenous cultural reclamation and place-based ecological co-management. Lastly, I turn to a multispecies exploration of social-ecological grief, using bears in North America as a face for reflection and consider who and what more is lost when old forests are degraded and gone. By asking the place question—“what place is this?”—of forests, or the Forest Question, my dissertation is thus an exploration of the connection and responsibilities to other place-based human and other-than-human communities in a rapidly changing climate. Author Keywords: critical topography, environmental grief, forests, multispecies, social-ecological relations, witness trees
Abundance and Distribution of Microplastics in Lake Scugog Catchment, Ontario
Plastic pollution is a growing concern, owing to its durability, ubiquity, and potential health impacts. The overall objective of this study was to assess the abundance and distribution of microplastics within Lake Scugog catchment, Ontario. This was fulfilled through two tasks (i) the development of a microplastic particle budget for the lake catchment, and (ii) the determination of the dry deposition of atmospheric microplastics in Port Perry, Ontario. The total input of microplastics into Lake Scugog (atmospheric deposition and stream inflow) was 2491 x106 mp/day, while the output (lake outflow and sedimentation) was 1761 x106 mp/day, suggesting that 29% of inputs were retained in the lake. The dry deposition of microplastics in Port Perry was 1257 mp/m2/day, which was high when compared to bulk deposition (37 mp/m2/day) in the same area. By quantifying the major pathways of microplastics better management techniques can be implemented. Author Keywords: Catchment, Dry Deposition, Microplastics, Ontario, Particle Budget, Plastic pollution
Community and conservation
Faced with the intersecting environmental crises of the 21st century, conservation organizations are searching for practices that produce better, more sustainable outcomes. However, they have often relied on forms of conservation which shore up rather than disrupt settler relationships to land in the form of fortress conservation and assumptions about the human-nature dualism. In this thesis, I examine a local land trust that intends to include community[-based] conservation into its conservation practices. In particular, I explore how the organization’s volunteers understand and construct the relationship between community and conservation, and the ways this might impact operations. Using a community-based research approach, interviews (n=17) were conducted. The findings indicate that the volunteers are demographically homogenous, leading to a homogenous, Western-science informed understanding of community[-based] conservation. This perspective views involvement of community as a direct trade-off with optimal ecological goals. As the volunteers wield uncommon power in organizational governance, difference in opinions toward missions or operations could lead to constraints on the organization. This study contributes to larger academic discourses on environmental volunteers, land trusts, and frames of conservation, and provides tangible recommendations to an organization attempting to include community[-based] conservation in its practices. Author Keywords: community-based conservation, environmental governance, environmental volunteers, frames of conservation, land trusts, power
Wetland Offsetting
Wetland loss in southern Ontario, escalated by development, is putting pressure on planners as they struggle to meet development needs while maintaining a balance with regional natural heritage. Wetland offsetting, coupled with strategic environmental assessment and sustainable community planning, offers a potential solution. A combined approach of literature review, interviews, focus group, and case study with Central Lake Ontario Conservation Authority (CLOCA) allowed me to present experiences and perspectives on wetland offsetting, site selection methods, and ecosystem service priorities. The focus group looked at organizational interactions and decision-making processes during wetland offsetting. Research resulted in creation of the Strategic Wetland Offset Site Selection Score Card (SWOSSS Card). Five of CLOCA’s past offsetting projects were reviewed to see what worked and what did not. Findings determined that use of strategic wetland offset site selection tools have the potential to provide an efficient means to quantify offsetting risk ahead of restoration efforts.

Shoreline Stewardship
This thesis aimed to determine what factors influence individual- and community-level shoreline stewardship attitudes and behaviours. Shoreline stewardship is part of the broader literature of environmental stewardship and place-based conservation. The needs and barriers limiting stewardship action were examined, as were the opportunities for increased impact. The Love Your Lake (LYL) program served as a case study into the impact of ENGO programming on shoreline stewardship among shoreline property owners in Ontario. This was investigated using a program workshop, interviews and focus groups with past program participants, and existing participant survey data. Community-Based Social Marketing principles were used to further examine the opportunities for increased impact on stewardship behaviour. The study found that the LYL program was effective in starting or continuing a conversation in communities around shoreline health. Some of the remaining needs and/or barriers included limited time at the cottage; limited knowledge of how to fix existing shoreline issues; low stock of local native plants and environmentally minded landscapers; ineffective messaging; a lack of interest, enthusiasm or concern; and weak environmental policies and governance of shorelines. Some participants also listed cost as a barrier, while others felt it had been well addressed already. Most participants thought that education could be a barrier but that it had been well addressed locally through LYL or other programming. Some key motivators and opportunities to increase shoreline stewardship included community building, increased lake association capacity, improved communication and marketing strategies, and persistence.

Analyzing the Effectiveness of Social Movements Opposing Fossil Fuel Infrastructure
Blocking fossil fuel infrastructure projects like pipelines is increasingly being seen as a legitimate way for civil society groups to reduce global carbon emissions. This research project is an exploratory case study of the Trans Mountain pipeline in British Columbia and its opposition. My research question asks, ‘What has each tactic/strategy of opposition in the campaign to stop the Trans Mountain pipeline expansion accomplished, and how have they been effective? How can they be done more effectively?’ Through interviews and an autoethnography, my research explores the effectiveness of activists in this campaign. I analyze the results of my findings within social movement theory and other activist definitions of effectiveness from my literature review. The more significant findings from my research are that activists need to do a better job educating the public on the issue, need to direct more of their resources towards promoting a solution to the issue and make alliances with other movements and groups. This research project contributes to the literature on the effectiveness of oppositional strategies and tactics of pipeline resistance, as well as social movement theory. Author Keywords: British Columbia, pipeline, protest, strategy, tactic, Trans Mountain
Role of Policy in Arctic Food (In)Security
Hunger is a significant concern in Canada, and even more so in the North, with 52% of Inuit adults in Arctic regions experiencing some level of food insecurity in 2012. Policy deficiencies are argued to, at the least, be partly responsible for this issue. This qualitative exploratory project aimed to answer the question: What is the role of food-related policy(ies) in household food security? A review and analysis of policy documents and academic literature at three jurisdictional levels, using the case of food insecurity in Nunavik, Québec, was conducted. The study identified 281 policies facilitating and 139 policies acting as barriers to food security. The highest proportion (27%) of facilitators related to economic accessibility of food and the highest proportion of barriers (93%) related to political accessibility of food. Only one previously identified factor influencing household food security in the region had a corresponding policy barrier associated with it. The study suggests that what is considered ‘food policy’ differs significantly between jurisdictions. Many of the same policies that act to facilitate some aspects of food security act as barriers to others. Policy barriers tend to be difficult to identify by their very nature. As a result, policy plays a complicated role in Nunavik food security status, representing a positive influence in some regards and a negative one in others. Author Keywords: Arctic, Food, Food security, Inuit, Nunavik, Policy
Nature without Balance
This thesis critically analyses the connection between ideology and nature, and in particular, aims to reflect on the dominant discourses on the topic of ecological crisis. The ecological thought framework that I adhere to rests on a combination of Frankfurt School and Žižekian theories. This combination is not without serious tensions and deviations; however, central to this project are the ways in which their respective works extensively critique ideology, and propose subversive alternatives to and new meanings of how we can conceptualize nature without domination. Dominant ideas and critiques of nature and natural history emerged during the Enlightenment era, and as Adorno argues, fell victim to a “reduction ad hominem,” or the claim that in order to free oneself, one must dominate, appropriate, and master nature. I claim that the extreme choices in environmental politics today - namely organic populism on one hand and increased technological intervention on the other - fail to account for the ways ‘nature’ is a socio-historical construct, and moreover, is situated within a false reality wherein the ‘essence of existence’ is reduced to technological mastery. What we encounter in this cautionary armoury of paradoxical approaches to nature, then, is the ideological currents of established belief systems. By exposing the illusions within the concept nature, such as the argumentative persuasion that there exists an inherent balance, the elementary cell of ideology reveals itself alongside revolutionary possibilities. Author Keywords: Crises, Critical Theory, Ideology, Nature, Slavoj Zizek, Theodor Adorno
Mythopoeia Sylvatica
Since British colonization of North America and the beginning of Anglo-speaking Euro-Canada and the United States, myth-making or representations of the forests have witnessed degradation and loss of old-growth forest ecosystems or intact sylvan landscapes. Canadian and American versions of the story of the North American Forests shared the same trajectory: forests as ‘wasted-land’ or the sylvan wilderness (terra nullius) divided into properties and cleared to “improve” the land for settlement/agriculture, forests as storehouses for timber and imperial expansion, forest landscapes and specific forest trees as identity politics and sources of industrial and economic power. While forests are recognized according to various stakeholders’ values today, what is commonly accepted as a forest varies widely. The meaning given to “forest” determines related terms and concepts, such as “sustainable forestry” and “reforestation.” This thesis addresses the issue of social-bioecological degradation, loss, and dis(re)membering of old-growth forests and problematizes traditional Western relationships with old wildwoods shaped by notions of space, politics, and economy. In the forest topos, the core question becomes which forest(s) are being imagined, represented, and remembered? Whose environmental imagination is shaping the landscape? As a critical topographical exploration of the North American forests through six witness trees, this thesis demonstrates how the meanings imbued in trees and wild woods come to determine the fate of the forests. It reveals how colonial values and trends persist in our societies still, and calls for an ethical social-ecological reimagining of the forests through traditions of ethical storytelling and environmental witnessing. Author Keywords: critical topography, environmental generational amnesia, environmental witnessing, forests, social-ecological systems, witness trees
Robert Bringhurst and Polyphonic Poetry
Robert Bringhurst states that polyphonic art is a faithful, artistic reflection of the multiplicity of the world’s ecosystems. This ecocritical perspective recognizes that human art informs our understandings of the world, and therefore artists have a moral obligation towards that world. In Chapter One I argue that mimesis should be reclaimed as a useful literary category since all art, regardless of intentions, has an effect on both culture and the natural world. In Chapter Two I argue that by reconnecting publishing craft and philosophy, our books can serve to bring us more in tune with the structures of the natural world. I conclude in Chapter Three by asking how a counterpublic consciousness can be cultivated, and how Bringhurst’s mission of transforming culture might be fully realized. Altogether, this view of literature offers an antidote to Western culture’s destructive tendencies towards the natural world. Author Keywords: Bringhurst, ecocriticism, mimesis, poetry, polyphony, typography
University Aged Millennials' Attitudes and Perceptions Toward Vehicle Ownership and Car Sharing
Car-sharing may have the potential to contribute to a more sustainable transportation system. The current research sought to answer the question: what are university-aged Millennials' perceptions and attitudes toward the adoption of vehicle sharing and private vehicle ownership? The research consisted of hosting six interactive focus group sessions with Millennial students, who currently do not own vehicles. Using a qualitative approach, I analyzed the discussions through a social practice theory lens. I suggest that skills, meanings, materials, and social interactions have an influence on the way in which a transportation option is perceived by Millennials. The results revealed that social norms surrounding vehicle ownership and car sharing are being developed, shaped, changed, challenged and reconstructed. If car-sharing businesses, universities, and governments wish to progress toward a more sustainable transportation system, they should recognize the importance of marketing. Author Keywords: Car ownership, Car sharing, Millennials, Sustainability, Transportation, University
EXPLORING THE EFFECTS OF WATERPOWER OPERATIONS ON RIVERINE ECOSYSTEMS ACROSS NORTHERN ONTARIO
In this study, we attempt to enhance current knowledge of ecological responses to riverine alterations from waterpower by using a bottom-up food up approach. A series of extensive and intensive study components were performed across northern Ontario, Canada, where biological (nutrients, dissolved organic matter (DOM) and periphyton) and physical (water level and thermal regimes) ecological indicators were examined in regards to alterations from dams and waterpower facilities. Overall, we found that the water levels and thermal regimes deviated from their reference condition at sites below the dams, whereas the biological indicators were more resilient to river alterations. Our results suggest that the characteristics of the watershed were influential in controlling the variability of nutrients and DOM resources in rivers within the boreal watersheds of northern Ontario, as well as the for the downstream recovery patterns of the physical indicators. The recovery of the periphyton communities downstream of the dams were also predicted to be cumulatively related to the physical alterations, nutrient availability and the possible displacement of invertebrate communities. Therefore, our bottom-up food web approach was not effective for better understanding how ecological responses from waterpower cascade through aquatic food webs, and instead multiple indicators should be used for examining the ecological responses in these particular river systems. Author Keywords: dissolved organic matter, ecological indicators, river alteration, waterpower facilities
