The development of viable solutions to the global threat of antimicrobial resistance requires a transdisciplinary approach that simultaneously considers the clinical, biological, social, economic, and environmental drivers responsible for this emerging threat. The vision of the Antimicrobial Resistance Mitigation (ARM) group is to build upon and leverage the present strengths of Virginia Tech in ARM research and education using a multifaceted systems approach. Such a framework will empower our group to recognize the interconnectedness and interdependent nature of this threat and enable the delineation, development, and testing of resilient approaches for its mitigation. We seek to develop innovative and sustainable approaches that radically advance detection, characterization, and prevention of antimicrobial resistance emergence and dissemination in human-dominated and natural settings...

A survey of the Save Our Streams (SOS) volunteers in Virginia documented their socioeconomic characteristics, their reasons for volunteering, their level of participation in SOS monitoring and other volunteering, their assessment of the validity and reliability of the SOS water quality monitoring procedures, and suggestions for program improvement. Common reasons for SOS involvement were to protect the environment, learning, teaching, be of service, and nature enjoyment. The most common length of participation in the SOS program was one to three years. Most volunteers felt that the SOS’s recommended procedures provided accurate measures of stream health, and most felt they did the monitoring procedures quite or very well. However, about one-third of all SOS volunteers monitored a stream less than once a year; about 20% did so the recommended four times a year. Volunteers generally rated program services provided by SOS as quite high. Program changes most favored included standardized training procedures across all of Virginia, and lobbying government agencies to use volunteer data to protect streams. A second tier of preferred services included special guest speakers about water and environmental quality, an annual meeting for all volunteer water monitoring groups in Virginia, paid full-time SOS regional coordinators, and random field spot-checks of the SOS volunteers’ work to assure quality data. Opposed changes were an easier certification test and removing the choice from volunteers on what streams they monitor. Reasons for dropping out of the program included too many other obligations and not enough time. Differences in reasons for participation and suggestions for program improvement are reported for Rookies, Fading Veterans, Active Veterans, and All-Stars among the SOS volunteers.

This dissertation explores strategies for addressing identity-related barriers to environmental problem-solving through the lens of two social-psychological theories: self-affirmation theory and moral foundations theory. Through one theoretical review, two online experiments and one in-lab experiment I explore, integrate and test theoretically grounded strategies for reducing the defensive information processing that can exacerbate intergroup divisions in multi-stakeholder settings. The specific objectives of this dissertation are to 1) integrate self-affirmation theory and moral foundations theory into the current knowledge about collaborative conservation (Chapter 2), 2) evaluate ways of tailoring environmental communication to better reach socially and politically diverse audiences (Chapter 3), and 3) experimentally test the effectiveness of an approach, based on self-affirmation theory, to facilitate productive discussion of complex, value-laden issues in group settings. Before presenting the results of this work, I provide a broad overview of the problem of group-based divisions in environmental conflict and the theoretical underpinnings of the dissertation (Chapter 1). Finally, I summarize the results and discuss the broader implications of the research (Chapter 5). The results of this research offer initial insights into how tools grounded in these theories can most effectively be applied to help alleviate identity-based barriers to environmental problem-solving.

With over 16,500 documented vacant commercial and residential units, roughly 20 miles of abandoned rail lines, a historic loss of approximately 330,000 residents, millions of gallons of annual surface water sewage discharges, and a decade-long failed water quality consent decree - Baltimore, Maryland lies at a crux of chronic challenges plaguing America’s formerly most economically and industrially powerful cities (Open Baltimore GIS [Vacancies Shapefile], 2017; “Harbor Water Alert” Blue Water Baltimore, 2017). Impending environmental threats in the “Anthropocene” (Crutzen, 2004) and increased attention to societal injustices warrant heightened inclusivity of social and natural urban functions. Socioecological inequities are often highly conspicuous in declining post-industrial American cities such as Baltimore. Chronic social, economic, and environmental perturbations have rendered some of once critical American infrastructure outdated, underutilized, and/or abandoned. Rivers, forests, rail corridors, as well as residential and industrial building stock are in significantly less demand than when America’s industrial age shaped urban landscapes in the late nineteenth/early twentieth centuries. Compounded by insensitive traditional urban development, these phenomena jeopardize urban social and ecological function. This thesis is an examination of contemporary urban ecology concepts as a systemic approach for revitalizing socially and ecologically marginalized urban areas, with an application in West Baltimore, Maryland neighborhoods. Through an examination of socioecological dilemmas and root causes, a conceptual procedure for urban blight mitigation along the Gwynns Falls corridor is proposed. Adopting an urban green infrastructure plan offers comprehensive alternative solutions for West Baltimore’s contemporary challenges. Master plans are proposed for the Shipley Hill, Carrollton Scott, and Mill Hill neighborhoods in West Baltimore. Site scale socioecological connections are suggested for the Shipley Hill neighborhood with contextual linkages in the surrounding neighborhoods. Additionally, policy considerations are explored for revitalizing Baltimore’s most vulnerable landscapes. By transforming derelict industrial infrastructure to dynamic socioecological patches and corridors, this work aims to enhance socioecological equity and connectivity. Negative aspects of Baltimore’s contemporary urban condition such as blight, high vacancy rates, ecological damage, population decline, and other symptoms of shrinking cities are deeply rooted in a complex evolution of social, environmental, and economic management. Current challenges facing Baltimore can be directly linked to a long history, specifically including industrialization and systematic segregation of neighborhoods. As the United States entered a period of stability following the industrial revolution, domestic manufacturing dwindled, causing a once strong workforce population to leave industrial mega-cities such as Baltimore. This population exodus left behind prior workforce housing and industrial infrastructure, much of which now nonessential to Baltimore’s contemporary urban functions. Housing vacancies and abandoned infrastructure are most noticeable in Baltimore’s predominately minority neighborhoods. Historically marginalized by systematic segregation tactics, “redlined” neighborhoods largely continue to lack sufficient social and economic capital for adaptation to a transformative new era in Baltimore’s history. Disparities in these minority neighborhoods have shown lasting consequences and continue to suffer from financial, social, and ecological neglect. However, progressive urban planning processes pose significant opportunity for equitable inclusion of historically marginalized urban communities through the introduction of green infrastructure. Because socioecological disparities in Baltimore are incredibly complex, an equally complex solution is necessary to adequately alleviate symptoms of declining cities. Although much research and literature has been cited in systemic solutions aiming to address the totality of these issues, practical implication of these strategies remains limited. This thesis aims to identify primary drivers of socioecological inequity as well as recommend policy and spatial solutions to alleviate symptoms of shrinking cites specific to Baltimore.

Cooperative Extension produces public value through educational programming that benefits the greater community. Forests provide numerous valuable benefits to society through the provision of ecosystem services. Cooperative Extension educational programming positively impacts forest owners, who in turn conduct actions that enhance ecosystem services. A heretofore unrecognized relationship exists between Cooperative Extension and ecosystem services that provides opportunity for mutual benefit. Applying ecosystem services values to Extension natural resources-related programmatic outcomes through benefit transfer provides an avenue for Extension to make significant advancements in monetizing public value. Beyond serving simply as a source of financial justification, however, linkages with ecosystem services also provide Cooperative Extension with opportunities to improve the design and delivery of educational programs, do a better job articulating an array of public benefits resulting from agency accomplishments, and optimize allocation of sparse resources and Extension efforts. This dissertation thoroughly explores these concepts by providing an overview of: Cooperative Extension in general and Extension forestry more specifically; public value in an Extension context; ecosystem services; ecosystem services valuation; benefit transfer, and; connections between these diverse topics. In addition, benefit transfer principles are applied to an existing Extension evaluation data set in attempt to monetize Cooperative Extension's impact, lessons learned are explored, and the Cooperative Extension public value discussion is re-framed as one aspect of overall continuous organizational improvement.

The Tea Party movement became a significant political force in American politics in 2009. Soon after their arrival on the national scale, this movement turned its attention to environmental policymaking. In particular, it spurred a strong opposition to local sustainable development initiatives. While this conflict has run its course in most places, it remains an example of the type of opposition future environmental or sustainability work may face. This three-part study is focused on determining the extent and nature of this opposition with particular emphasis on how it reflected the broader conflict between individualism and collectivism. First, we analyzed general interest in the topics associated with the opposition using media interest and internet search trends. Next, we evaluated what was driving this opposition through rhetoric analysis of local Tea Party organizations from across the country. This helped uncover several of the predominant themes in the opposition, including a belief in American Exceptionalism, concern over our system of Governance and a strong preference for individualism. Lastly, we conducted a case study of the conflict in Roanoke, VA. This allowed us to map out the specifics of one segment of the broader conflict and explore the driving themes further. The results of all three parts point to a substantial, but diffuse, opposition that was driven in no small part by a preference for individualism. This work demonstrates that individualism can be used as a lens through which a fuller understanding of this, and future, opposition of environmental legislation may be generated. Master of Science

This dissertation examines how trust develops in landscape level collaborative natural resource management efforts. I took a case study approach to research four projects in the Collaborative Forest Landscape Restoration Program (CFLRP). I conducted qualitative analysis of interviews, notes and observations from site visits and archival documents to understand the role and function of trust within my four case studies. The results are organized into five chapters: an introduction chapter, three manuscripts intended for stand-alone publication (Chapters 2-4), and a conclusion chapter. Chapter 2 reports on the development and function of trust within the four collaboratives I studied. Chapter 3 discusses the roles of facilitators and coordinators for engendering and maintaining trust. Chapter 4 examines three of the four case studies and compares the observed trust outcomes to the literature on traditional forms of public involvement. Finally, Chapter 5 synthesizes the findings from Chapters 2-4. These results provide useful information about the types of trust that contribute to successful collaborative efforts, as well as identify some of the practices and structures that engender those types of trust.

Anecdotal evidence in the media and from personal conversations suggests that inflammatory rhetoric in the collaborative governance setting is increasing, especially during public meetings about sustainable development projects. Planners, mediators, facilitators, and government officials are facing a shutting down of public deliberation by "new activists" who are engaging in public forums in very emotional and uncompromising ways. This dissertation is a direct examination of actions by new activists. It includes two case studies in Roanoke, Virginia, as well as a broader look at the inflammatory rhetoric and disruptions in local public meetings now occurring across the country. Ph. D.

This dissertation explores the discursive production of, and response to, environmental disaster. The project is contextualized through the case of the 2010 Deepwater Horizon disaster in the Gulf of Mexico. By interrupting traditional perceptions of environmental disaster, this project frames socio-environmental disasters as a normal and increasingly experienced part of global hydrocarbon capitalism. The project purports that disaster is embedded within the current global economy and the high-]modernist ideologies that underlie it. As such, the strategies and techniques employed to respond to environmental disaster are intimately bound up within the same systemic processes that have created them in the first place. Moreover, because instrumentalist responses are quickly employed to mitigate disaster, the systemic factors productive of disaster remain concealed. Environmental disaster is thus a process of hydrocarbon capitalism rather than a product of it; as such it can, among other categories, be understood as manageable, profitable, and litigable. This research also highlights the normalization of chronic socio-environmental disaster though sensationalistic perspectives on acute disaster. This project explores the potential for resistance through artistic endeavors, highlighting how the discursive processes that construct traditional power/knowledge formations of environmental disaster might be subverted through non-traditional means. While the framework of eco-governmentality is especially useful in highlighting the problematic social relationships to nature, the project nonetheless acknowledges that counter-discourses for are likely to be appropriated by industry for the purpose of new enterprise and profit.

This dissertation examines three relationships between nature centers and their local communities. First, what are the values provided by local centers as perceived by community members? Second, what factors lead community members to support local centers? And third, what are the constraints to visiting local centers as perceived by community members? We surveyed random samples of community members living around 16 diverse nature centers across the United States and conducted quantitative and qualitative analyses to address these questions. Chapter one introduces the study and provides a literature review of theories and empirical research related to the research questions. Chapter two reports the results of an exploratory factor analysis on the level of importance communities assign to fourteen nature center services. The factor analysis revealed four underlying values: environmental connection, leisure provision, civic engagement, and community resilience. Chapter three tests sixteen hypothesized predictors of community support for nature centers. All these variables were significant, suggesting people volunteer at, donate to, or respond to threats at nature centers for a range of reasons. These include those related to supporting nature center missions (e.g. environmental connection significance and commitment to nature) but also other reasons such as friends' and family's perceptions of nature centers and assessments of the center staff members. Chapter four explores constraints that emerge during different stages of the decision-making process people go through when considering whether or not to visit a local nature center. The greatest constraints emerge in early stages (e.g. center awareness) and late stages (e.g. limited finances, transportation, and time) of decision-making. Chapter five discusses the study's implications to theory, including ecosystem service and educational leisure setting valuation, environmentally significant and charitable support behavior, and leisure constraints, as well as nature center practice. Centers that consider these implications might better serve their local communities and achieve their missions. Ph. D.

African immigrants in the United States (U.S.) experience immense challenges in the form of poverty, unemployment, and underemployment. One strategy used by community development organizations to address these challenges is the development of farm entry programs that assist immigrants in beginning and sustaining farm operations in the United States. Organizations such as Cooperative Extension, resettlement agencies, and African mutual aid associations have developed beginning farmer programs that provide a supportive foundation for immigrant farmers to gain access to farmland, technical training, and markets. Returning to farming provides African immigrants with a series of benefits including supplemental income, food security, and social integration. Drawing upon social capital theory, this study offers a novel approach to measure the community and economic development outcomes of immigrant farming programs. In this mixed-method program evaluation, immigrant farming programs are analyzed as social networks that connect immigrants to technical training, farming resources, and community members who can provide access to markets. Data were collected through a survey of 112 agricultural educators working with immigrant farming programs across the United States. Data were also collected through case studies of a Midwestern program and a Southern program. The case studies include two focus groups and 20 interviews with individuals associated with the programs as participants, agricultural educators, and community partners. Regression tests were conducted to determine the social capital factors associated with well-being outcomes occurring through the programs. The models show that interaction outside of the program, and access to information are positively associated with well-being outcomes. Analysis of variance tests show differences between programs with African immigrant participants and programs with participants from other world regions. Programs with African immigrants tend to have more requirements to use farming resources compared to programs with immigrants from other world regions. Qualitative analysis found that female African immigrant participants have a lower levels of agency compared to male African immigrant participants. The study concludes with a discussion of recommendations for implementing and evaluating immigrant farming programs, as well as applying social capital theory to the field of agricultural education.

The United States Forest Service planning processes, which are driven in large part by the requirements of the National Environmental Policy Act (NEPA), are a part of all major (and some minor) land management decisions by the agency. The outcomes of these processes are the result of multiple factors, many related to the manifold smaller incremental decisions made by agency personnel directing the processes. Through qualitative review of 21 NEPA documents and 5 case study processes in which we interviewed decision makers, team leaders, and team members, this study examines those incremental decisions and the factors that drive them. Risk emerged as a dominant lens through which agency personnel weigh and make process-related decisions. We identify the different types of risk perceived by agency actors and the risk management strategies they employ. Our interviews suggest that different actors within the agency tend to assume responsibility for responding to different forms of risk associated with particular tasks. Most time and energy appears to be focused on minimizing process-related risks, especially those caused by external entities in the form of public opposition and threats of appeal/litigation, rather than resource-related threats. We discuss the potential implications of this focus and its associated strategies on organizational and social learning within agency planning processes, on adaptive ecosystem management, and internal agency relationships and morale.

This dissertation examines how the U.S. Forest Service implements and uses public involvement during the agency's planning processes as mandated by the National Environmental Policy Act. Focused from the perspective of the agency personnel leading the process, this study is informed by both quantitative and qualitative analyses. Chapters two and three report the results of a web-based survey completed by 489 Forest Service employees. Chapter two shows that these employees most commonly view public involvement as a means for obtaining substantive information that could be used to improve the management decision. Chapter two also reveals that agency personnel who view public involvement as only a procedural requirement tend to achieve less positive process outcomes, but those who explicitly create opportunities for interactive dialogue with the public tend to achieve more positive outcomes, including more positive perceptions of the public involvement process and agency-public relationships. Chapter three shows that agency employees commonly believe more public influence should and does happen during the earlier stages of the planning process, but that agency employees also desire more public influence throughout the process. Chapter four uses qualitative interviews with 16 of the survey respondents to build upon the insights from chapter three. By exploring what may be constraining public influence from occurring at the desired levels, chapter four describes how agency personnel can impact how much public influence happens. The final chapter highlights the importance of looking beyond the specific public involvement technique employed during the process to the nature of the agency-public interactions. Agency personnel who are willing to engage in extra effort to translate public values into substantive management concerns generally achieve more desirable forms of public influence. They also help satisfy the public's desires to communicate their visions for the management of the National Forests. Key barriers include heavy workloads, negative views of the public, and over-reliance on minimum procedural requirements. Conversely, strong normative beliefs about the positive role of the public in agency planning, leadership commitment, and a recognition of the discretion afforded planning personnel can lead to higher levels of desired public influence.

This dissertation examines the relationship among practices and policies of waste/ing and economic structures to make visible the implications of vehicle disposal policies for environmental policy and theory. Consequently, I attempt to build upon the small body of literature that is now critically engaging with waste production and resulting actions/inaction in the form of policies of management. In doing this I use waste as a lens to examine the interrelationships among environmental degradation and economic and political structures. Further, I examine these phenomena in relation to a physical object, the automobile, to add materiality to abstract notions of waste as it relates to both the political and the economic. Through vehicle recycling policies, I analyze how underlying economic structures in contemporary capitalism result in specific responses to the "problems" of waste as well as how the related responses, or "solutions" perpetuate an un-ecological industrial system which severely restricts the possibilities of making substantial change in the production of environmental harms.

Completed as a series of manuscripts, this dissertation reflects four aspects of my research into the intersections of conservation and sustainable development as practiced by conservation land trusts and community landcare groups, as well as by faculty and staff at land grant universities. The first paper included in this dissertation explores "Conservation 2.0" strategies being developed and employed by land trust across the US to integrate social and economic development goals into their conservation missions. The second paper explores one of these Conservation 2.0 strategies in greater detail, in particular the support of ecological entrepreneurship by land trusts and partners they involve in "ecological entrepreneurship support networks". The third piece emerged out of five years of engaged research with Catawba Landcare as one community landcare group in the region. As a means to capture the development path and history of the organization as well as to facilitate its path forward, I developed a dynamic content management system (CMS) based website for the group, which is explained in Chapter 4. The fourth and final piece of this dissertation is a collaboratively written piece that examines the relationship between Catawba Landcare and Virginia Tech using four theoretical lenses for community capacity building, ultimately proposing one engagement strategy for land grant universities to build and strengthen social infrastructure in their neighboring communities. In total, this collection of works chronicles a larger endeavor to explore place-based sustainability and the role of institutions and civil society in constructing a more sustainable future. Ph. D.

Faith-based environmentalism involves caring for the earth through a reflection of one's morals, values, and faith. In this study, religious leaders that are actively involved in faith-based environmental groups were interviewed and congregational members surveyed to explore belief systems and attitudes with the goal of understanding how to increase program participation and make faith-based environmental groups more effective. Twenty environmental religious action leaders were interviewed. Survey questions were also administered to 10 church/synagogue congregations within the study region. Interview results showed that action leaders were interested in secular and religious partnerships, although they felt that some partnerships may be more appropriate than others. Leaders felt that clergy support was essential to program success. The extent to which faith contributes to one's identity could be a factor for participation for some congregants. Leaders thought that a combination of hands-on, scripture-based, and sermon-based approaches, as well as integration throughout church or synagogue practices and activities would increase efficacy. Political perceptions were cited as a reason for non-participation. Congregational survey results showed that environmental commitment positively predicted program participation, whereas political conservatism was an inverse predictor. Faith identity, secular and faith partnership attitudes, religiosity, church attendance, and attitudes about support from church leadership did not impact whether or not congregational members participated in faith-based environmental programs. Program preferences and environmental views were analyzed to determine any differences. Preferred learning methods included hands-on activities and expert guest speakers. Congregants most viewed environmental problems as being a moral, social justice, and economic issue. Master of Science

In this dissertation I explore discourse around the environmental risks of nanotechnology, and through this study of nanotechnology make the case that the dominance in risk discourse of regulatory science is limiting policy debate on environmental risks, and that specific initiatives should be undertaken to broaden debate not just on nanotechnology, but generally on the risks of new technologies. I argue that the treatment of environmental risk in public policy debates has failed for industrial chemicals, is failing for nanotechnology, and most certainly will fail for synthetic biology and other new technologies unless we change how we describe the impacts to people and other living things from the development and deployment of technology. However, I also contend that the nanotechnology case provides reason for optimism that risk can be given different, and better, treatment in environmental policy debates. I propose specific policy initiatives to advance a richer discourse around the environmental implications of emerging technologies. Evidence of enriched environmental policy debates would be a decentering of language concerning risk by developing within discourse language and practice directed toward enriching the human and environmental condition.

To explore the institutional resilience of community-based conservation, I undertook empirical research in the Annapurna Conservation Area (ACA), Nepal, a protected area managed by the Annapurna Conservation Area Project (ACAP) and local communities organized into 56 Conservation Area Management Committees (CAMCs). I conducted scripted interviews with 212 members of 30 representative CAMCs, 13 ACAP staff members who closely monitor those CAMCs, and 868 local villagers who are the beneficiaries of the conservation programs. The field research was undertaken during the summer of 2007 and fall of 2008. Both quantitative and qualitative data were collected and analyzed. I estimated capital stocks and assessed the organizational resilience of each CAMC during and following the Maoist insurgency. I used confirmatory factor analysis to develop scales for measuring the two theoretical constructs of legitimacy and institutional resilience, the latter of which refers to the overall system of community-based conservation in the area. I used the adaptive cycle framework of growth, maturation, collapse and reorganization to assess changes in structures and processes and to explore the past, present and possible future trends in ACA. Villagers largely considered the CAMCs as legitimate institutions, and their executive members as trustworthy. CAMC members understood the organizational mission and were confident about assuming greater management responsibility of the area in the near future. Human and social capital stocks were positively related to the resilience of the CAMCs. Particularly, themes of intra-committee trust, help networks, and the duration of members' tenure on the committees were important. Furthermore, natural capital stocks showed a parabolic relationship with organizational resilience; the most resilient CAMCs had moderate amounts of natural capital under their jurisdictions. The scales used to measure legitimacy and institutional resilience were reliable, and showed a significant positive correlation with each other. Five variables significantly predicted the villagers' perceptions of legitimacy: performance assessments of CAMCs, social norms as measured by perceptions of peers' attitudes towards CAMCs, empowerment as measured by villagers' perceptions of their influence in the CAMCs' decision making processes, perceived benefits and costs associated with having the CAMC in a village, and reported levels of personal participation in CAMCs' activities. The conservation institution appeared to have been resilient to the insurgency, as the system maintained its identity throughout, avoided alternative undesirable states, and entered into the reorganization phase following collapse. All forms of capital and institutional performance decreased to some extent during collapse but institutional memory, available capital and some structural changes facilitated reorganization. The institutional system is reorganizing along the original regime, but it has also developed an alternative pathway of a new governance model for the area that will transform the present regime in the near term.

Since the 1970s, the institution of fire management has been in a frustrated transition from fire suppression and control to ecologically informed fire management. Administrative boundaries, professional specializations and organizational incentives and funding mechanisms have stalled the adoption of landscape scale ecological fire restoration as a guiding paradigm. Using a case study approach, this dissertation examines the potential of a multi-scalar collaborative network, the US Fire Learning Network (FLN), to catalyze the changes necessary to overcome the frustrated transition. Established in 2002 in an agreement between the USDA Forest Service, The Nature Conservancy, and the US Department of Interior, the FLN operates at landscape, regional and national scales. In this multi-scalar context, the network utilizes planning technologies, communication modalities, and interpersonal interaction to link participants at each scale and motivate them to enhance their collaborative ecological restoration planning capacities. The network directly addresses the challenges of the frustrated transition by enabling practitioners to collaborate across administrative and disciplinary boundaries, develop expertise in ecological fire restoration planning and management, and to inform policy changes at the federal level that can create new incentives and funding mechanisms that support landscape scale ecological restoration. While institutional transformation has yet to occur, the FLN sets the stage to address the core challenges that fire management practitioners and organizations face as they engage in landscape scale ecological fire restoration. This work provides theoretical and practical insights to collaborative planning research by introducing new forms of collaborative practice, describing how collaborative planning can be conducted across multiple scales simultaneously, and establishing how multi-scalar collaborative networks may be able to catalyze institutional change necessary to respond to complex cross scalar environmental problems.

Urbanization, changing forest landowner values, and restructuring forest industry are creating challenges for the active management of small parcels of forestland. Many traditional service providers are reluctant to service small acreage parcels due to economies of scale, shrinking profit margins for unprocessed stumpage, and changing landowner expectations. They do not understand traditional forestry operations and do not know where to look for service providers. A gap in our nation's forest system has emerged. A new market opportunity exists for service providers willing to work with small-scale forest landowners. In this study, over sixty forest service providers working with small acreage or amenity oriented clients were interviewed to determine how their business is structured, how they charge for the services they provide, what reactions they get from their clients, and how successful they perceive themselves to be. Informants came from a wide variety of professional backgrounds, including forestry, logging, arboriculture, landscaping, and woodworking. In addition, about 20 public-forest professionals were interviewed to determine how they and their programs are changing in response to emerging conditions. Successful service providers generally charge by some measure of time and materials rather than by commission. They exhibit a willingness to diversify their business to offer a bundle of services, and to cooperate with professionals in related industries. Value-added processing and creative marketing assist service providers in achieving a profit from small-scale tracts with traditionally low-value products. Lessons learned from these early adopters will assist other service providers interested in working with small acreage private landowners. Master of Science

The main argument of this dissertation is that the White Mountain Apache Tribe's appropriation of ecological restoration played a vital role in reinstituting control over knowledge production and eco-cultural resources on the Fort Apache Indian Reservation in the second half of the twentieth century. As a corollary, I argue that the shift in knowledge production practices from a paternalistic foundation to a community-based approach resulted in positive consequences for the ecological health of the Apachean landscape and Apache culture. The democratization of science and technology on the reservation, therefore, proved paramount to the reestablishment of a relatively sustainable Apache society. Beginning with the Indian New Deal, the White Mountain Apache slowly developed the capacity to employ ecological restoration as an eco-political tool to free themselves from a long history of Euro-American cultural oppression and natural resource exploitation. Tribal restoration projects embodied the dual political function of cultural resistance to and cultural exchange with Western-based land management organizations. Apache resistance challenged Euro-American notions of restoration, nature, and sustainability while maintaining cultural identity, reasserting cultural autonomy, and protecting tribal sovereignty. But at the same time, the Apache depended on cultural exchange with federal and state land management agencies to successfully manage their natural resources and build an ecologically knowledgeable tribal workforce. Initially adopting a utilitarian conservation model of land management, restoration projects aided the creation of a relatively strong tribal economy. In addition, early successes with trout, elk, and forest restoration projects eventually granted the Tribe political leverage when they sought to reassume control over reservation resources from the Bureau of Indian Affairs and the Fish and Wildlife Service. Building on this foundation, Apache restoration work significantly diverged in character from the typical Euro-American restoration project by the 1990s. While striving toward self-sufficiency, the Tribe hybridized tribal cultural values with Western ecological values in their restoration efforts. These projects evolved the tripartite capacity to heal ecologically degraded reservation lands, to establish a degree of economic freedom from the federal government, and to restore cultural traditions. Having reversed their historical relationship of subjugation with government agencies, the Apache currently have almost full decision-making powers over tribal eco-cultural resources. Ph. D.

This dissertation examines the environmental discourse of the USDA Forest Service, focusing on the language of ecosystem management (EM). A two pronged approach was employed: eleven interviews were conducted with agency executives (chapter two); thirty-three interviews were conducted with agency staff specialists and decision-makers, working at the agency's operational levels (chapter three and four). Differences between how agency executives view EM and how agency operators view EM were identified. Chapter two shows that agency executives generally believed that the process of EM is ingrained in the agency. Chapter three explores this assertion at the forest and district levels, and reveals conflicting stories concerning the current practice of EM. Agency operators explained EM as a process driven by ecological science, but also revealed an alternate planning process. The alternate planning process is driven by the agency's budget and strict employee roles. Through qualitative analysis of interviews with agency operators, a model of how agency operators construct agency planning was created. It illustrates the potential mismatch between planning focused on ecological science and an agency focused on budgets, cost-benefit calculations, and strict employee roles. The model also shows that agency operators described active and passive publics in their constructions of agency planning. Chapter four focuses on these constructs of the public, and shows how they are partly created by agency interpretations of the public involvement processes required by the National Environmental Policy Act (NEPA). In some cases, the agency applies a standard for public participation (substantive sieve) that requires publics to couch their concerns in scientific or legal terms. Publics that are able to navigate the substantive sieve are typically viewed as active publics, while those that cannot meet this standard are viewed as passive publics. A feedback mechanism was identified between constructs of the public and agency process; constructs of the public shape agency process and agency process shapes agency constructions of the public. The dissertation concludes by showing that agency focus on budgetary targets and the use of the substantive sieve can be understood as attempts to instill accountability into a decentralized agency with an ambiguous mission.

The concept of Sustainable Forest Management (SFM) has been promoted in the past few decades all over the world. Non-industrial private forest (NIPF) owners play an important role in that aspect in the U.S. because of their number (about 16 millions), the size of forest land under their control (about half of all forest land in the continental US), and the dynamism of their population (increasing number of new owners). This study sought to better understand how NIPF owners come to a decision for adoption (or non-adoption) of SFM practices. We developed a theoretical model combining four theories (the Value-Belief-Norm theory, the Theory of Planned Behavior, the Elaboration Likelihood Model, and the Innovation-Diffusion Process) to explain NIPF's decision making. Using multivariate analyses, we determined which elements of the developed theoretical model were significant in explaining adoption of eight groups of practices. Overall, some of the most significant predictors of adoption we identified were technical assistance, motivations for owning land and the use of a written management plan. Particular attention was also directed toward the eventual relationship between education and adoption of SFM practices and it was found that NIPF owners who attended educational programs tended to be likely adopters compared to those who did not attend any educational program. Since SFM was not limited to the US, we also analyzed the concept of SFM with the same goals as in the US, but under a completely different context (socio-cultural, economic and ecologic) in Africa, through the community-based natural resource management (CBNRM) system. We used four case studies and focused on criteria such as participation, equity (both procedural and distributive, power devolution, trust, etc) to analyze how CBNRM works on the field, what lessons to take from the cases to better ensure the goal of sustainability of the resources.

This two-part research project evaluated the effectiveness of interpretive messages at Fossil Butte National Monument in conveying knowledge about the place and its resources and promoting respect for the fossil resource. The first study measured the short and long-term knowledge gains from a trip to the Visitor Center and the influence of a specially designed fossil respect message on the fossil protection beliefs of Monument visitors. The Visitor Center was successful in conveying information about the fossil resource and story of Fossil Lake, and that knowledge was retained for at least several weeks. However, neither the Visitor Center nor the special message, were successful in improving the fossil respect beliefs of respondents. The second study combined a visitor survey with direct observations of visitor behavior to evaluate the effectiveness of interpretive materials along a nature trail in improving the knowledge of ancient Fossil Lake, increasing fossil respect beliefs, and reducing depreciative behaviors. Six different treatments were applied that evaluated an interpretive sign, box of fossils that visitors were invited to touch, and participation in an interactive interpretive program. Only the interpretive program increased knowledge of the Fossil Lake story. None of the trail interpretive materials improved fossil respect beliefs. The sign was somewhat effective in reducing entry into a closed research quarry. While it is generally thought that those most knowledgeable about natural resources will have the higher resource protection beliefs, Fossil Butte visitors who reported being the most interested in fossils had the greatest knowledge of the Fossil Lake story but had the lowest fossil protection beliefs. Therefore, there was some evidence that fossil enthusiasts were the least likely to respect the resource. Ph. D.

Developed forest camping has received little attention in the recreation research since the late 1960s and early 1970s. Changes in socio-demographics, technology, and the public's expectations for amenities over the past forty years suggested that the nature of the developed camping experience may have changed. Thus, the purpose of this study was to understand the modern developed forest camping experience and associated meanings and the influence of technology on developed forest camping. In-depth interviews were conducted in the Mount Rogers National Recreation Area with thirty-eight camping groups in three campgrounds which varied in their level of development. Developed forest camping experiences were described by participants as a combination of what they were doing (i.e., activities), who they were interacting with (i.e., social interaction), where they were camping (i.e., setting), and what they were feeling while they were there (i.e., psychological states/feelings). The camping experience occurred in stages and it emerged over the course of participants' trips, with emotional highs and lows. Camping was a social experience, with participants defining much of their experience in terms of who they were with. The developed camping experience was influenced by the natural environment, particularly scenic beauty and other aesthetic setting qualities. The majority of participants in this study suggested that they were able to get a nature-based experience even in highly developed camp settings in which large motor homes, televisions, and satellite dishes were common. Participants used a range of camping gear and electronics, and this technology was important to promote comfort and conveniences and for a distraction during inclement weather. The associated meanings of developed forest camping were restoration (i.e., rest, escape, and recovery), family functioning, special places, self-identity, social interaction, experiencing nature, association of God and nature, novelty, and the opportunity for children to learn. Restoration was the most commonly expressed meaning across all three campground types. The most commonly expressed life-context meanings were restoration and sharing positive family memories and stories. These family memories and stories often developed into important camping traditions. Recommendations for recreation managers, study limitations, and opportunities for future research are identified and discussed. Ph. D.

Wildfire can be an extremely destructive force, especially when it reaches our nation's ever-increasing wildland-urban interface (WUI) area. To address this issue, state and federal agencies and cooperative education programs have begun to promote homeowner responsibility and wildfire vulnerability minimization practices as a means for WUI residents to take a proactive approach to protecting their homes from wildfire. This research provides resource managers with a new understanding of the processes through which WUI residents receive, interpret, and reconstruct wildfire messages, which will allow them to better assess their wildfire education programs. Results from this study suggest that WUI residents negotiate meanings for wildfire messages by externalizing and/or internalizing the hazard and its solution, and that these interpretations are strongly related to residents' behavioral response. This study also reveals significant discrepancies between WUI residents' central values and program goals; whereas fire programs generally highlight risk to homes and structures in the WUI, residents were typically far more concerned with their homes' contents and the environments within which their homes are situated. The insights provided by this study will increase program managers' ability to remedy these discrepancies and improve the effectiveness of wildfire vulnerability minimization programs and messages.

Article 1 As forest ownership continues to change, forestry must change to be relevant to its new constituency and client base. Market segmentation can help in this task. There is no such thing as an average forest owner. This study assessed the motivations and forest practices of 661 new owners of forested lands ranging in size between 2 and 50 acres. The study focused on rapidly growing counties in Virginia. Cluster analysis techniques were used to identify six market segments: Absentee Investors, Young Families, Forest Planners, Preservationists, Farmers, And Professionals. Only the smallest market segment (Absentee Investors, n = 26) reflects motivations and forest management interests that somewhat resemble "traditional" forest landowners. The results suggest that "lifestyle" concerns are the major motivations of these new owners and seemingly determine receptivity to professional forestry advice. This analysis helps understand these differently motivated segments and suggests possible marketing strategies professional foresters can use to "sell" forestry and active forest management. Article 2 Land managers increasingly are seeking to promote management of private forestland that transcends political and ownership boundaries. Descriptive analyses were used to characterize new landowners' intentions to participate in active management, both within individual property boundaries and in cooperation with neighboring landowners. The study also describes obstacles that these new owners perceive constrain their participation in active management. Further analysis explores potential differences in these variables related to amount of land owned, attitudes about private property rights, trust in forestry professionals, and attitudes about clearcutting and harvesting practices. The results suggest that private property rights are not an insurmountable problem to ecosystem management efforts. The forestry profession, however, seems to suffer from an invisibility problem among the population of new landowners. The very audience that ecosystem management programs target (owners of fewer than 20 acres of forestland) perceives itself to be least relevant to the message of cooperation. In fact, the biggest obstacle identified was that these new landowners have never thought about participating in active management, either within or across property boundaries. Ph. D.

By listening to peoples' constructed stories of special places, the average person begins to understand why and how attachments to places form. This study concerns the attachments residents of Isle au Haut, Maine possess on the remote island, which borders part of Acadia National Park. The purpose of this study is to uncover social components of both place attachment and place identity among island residents as well as explain the process by which those residents form attachments. Twelve interviews were conducted both on Isle au Haut as well as nearby Mount Desert Island. Qualitative data were collected from a purposive sample of island residents and National Park Service employees who are responsible for managing the park on the island. In-depth interviews were the sole means of data collection and provided detailed stories of life on the island and attachments that have formed. This study uses grounded theory techniques in data analysis to ultimately form a theory grounded in the collected data. The findings from this study indicate that social interaction is key to residents forming an attachment to Isle au Haut. Further, three major social constructs emerged from the data analysis. Those constructs are sense of community, shared purpose, and shared history, all of which were found to contribute to place identity and place attachment among the residents. The results also suggest place identity as more salient than place dependence in residents' narratives concerning their attachment to the island. Master of Science

Residential non-industrial private forest (NIPF) owners within the Wildland/Urban interface are an increasingly important forest owner demographic. An increase in rural residential land use is fragmenting historically large contiguous forestlands. Consequently resource management has become decentralized. NIPF-landowners, as the new land managers, must now be capable of creating resilient forest ecosystems at the landscape scale. To overcome this issue landowners and resource managers at all levels of decision-making (including landowners) must come to understand how social structures such as psychology, organizations, institutions, and culture are linked to behavior and the physical world. Collaborative Interface Modeling (CIM) has been created in response to an information gap that exists between the social and natural sciences at the site scale. CIM reveals the causal linkages between land use decisions and their effects allowing landowners to more closely trace and investigate their management policies, behaviors, and feelings as well as the consequences of those behaviors. A demonstration of the CIM process with residential forest landowners is conducted to evaluate the process and detect possible implications of encroaching development on the Jefferson National Forest in Montgomery County, Virginia. A focus on fuel wood collection was established because it has been noted as a potential source of negative impact. Possible implications and improvements to the CIM process are also noted.

The purposes of this study were to examine 1) understandings of science expressed in formal salmon recovery policy discourse; 2) rhetorical practices employed to justify or undermine claims about salmon policy 3); and patterns of understandings of science and associated rhetorical practices between social categories of actors. This research contributes to scholarship in public understanding of science, discourse studies, and natural resource policy. A constructivist discourse analysis was conducted using qualitative methods to analyze transcripts from over one hundred congressional hearing witnesses representing a wide diversity of stakeholder groups. Multiple coders organized discourses into analytic categories, achieving a final proportional agreement of 80% or greater for each category, at the finest scale of analysis. Stakeholders employed a collection of prototypical understandings of the nature of science, boundaries of science, and roles of science in decision-making. The process of science was described as impartial and ideal, a way to reduce uncertainty through consensus and peer-review, and subject to changing paradigms. Scientific knowledge was sometimes represented as "truth" and other times as tentative, and scientists were portrayed as independent and objective as well as captured and interest-driven. Witnesses described science as separate from and superior to politics and management. Testimony included descriptions of science?s role in developing decision alternatives, selecting among alternatives, and evaluating and legitimating alternatives. Stakeholders used these understandings of science to construct justifications to support their claims about salmon policy and undermine opposing claims. Science-based justifications included externalizing devices, construction of consensus, category entitlement, and extreme case formulations. Other justifications invoked local control, treaty rights, and local knowledge, or relied on interest management. This study has extended the theory and method of empirical discourse analysis, and produced a taxonomy of understandings that should be transferable to studies of similar policy settings. Additionally, conclusions from this study about differences between social groups in the presence, distribution, and frequency of expression of the discourses might be developed into propositions for further testing. Finally, the study has implications for communication about the role of science in collaborative natural resource decision-making processes. Ph. D.

Past research has shown that interpretive tour visitors at Okefenokee National Wildlife Refuge do no better than other visitors on knowledge and value questions about federal wilderness areas and national wildlife refuges. Tours into the Okefenokee Swamp Wilderness are conducted by a National Wildlife Refuge concessionaire. Interpretive tour guides participated in a training session on the purposes and values of wilderness and wildlife refuges. Visitors who took guided interpretive tours in the spring of 2001 with trained and untrained guides completed knowledge surveys immediately after taking the boat tour. Results indicate that there were no differences in visitor knowledge scores with trained versus untrained guides. A small sample of interpretive tour visitors was also interviewed in an effort to understand the meanings they ascribe to wilderness. Visitors were able to describe and articulate their views of wilderness with considerable clarity. Recommendations for future research include monitoring the guides' interpretive messages, conducting more in-depth interviews with visitors and guides, assessing visitors' and guides' prior knowledge of wilderness and wildlife refuge purposes and values, and developing guide training based on the principles of persuasive communication.

Truly unique and innovative solutions are needed to resolve today's complex and controversial environmental issues (e.g., biodiversity loss, global warming, cultural evolution, etc.). In response to these concerns, a variety of applied science programs have emerged to help people make better decisions about the environment. Each of these programs (e.g., conservation biology, restoration ecology, sustainable forestry, environmental toxicology, and others) produces specialized knowledge that is used to achieve specific social and environmental goals. For example, the peer-reviewed, scientific analyses published in Conservation Biology are most likely concerned with the goal of preserving biological diversity, whereas the equally scientific and respected analyses published in Forest Science are most likely concerned with the goal of sustaining timber yields. Likewise, studies in environmental toxicology investigate risks to human health by environmental pollutants, while stud! ies in ecological restoration serve to maximize the integrity of natural systems. Unfortunately, these diverse forms of knowledge offer multiple and often conflicting ways of thinking about the environment. Public ecology is a response to this dilemma. The primary goal of public ecology is construct common ground between people's diverse beliefs and values for the environment. Toward this end, public ecology is an interdisciplinary and collaborative approach to environmental science and politics. Public ecology integrates perspectives from the social and natural sciences, the humanities, and public understandings of the environment. Public ecology is not only a cross-cultural and comparative form of environmental studies, it is also a citizen science that encourages all concerned stakeholders to participate with research specialists, technical experts, and professional decision-makers in developing creative solutions to persistent environmental problems.

Environmental quality is a construct that has currency at the interface between science and policy—it is used both to describe current conditions as well as prescribe desired future conditions. However, environmental quality has a multiplicity of definitions, owing to: a) the fact that there are a number of terms (or "sub constructs") taken to be synonymous with environmental quality (i.e. environmental health, sustainability, biodiversity, integrity, and the like), and b) the fact that each of these sub constructs, in turn, have multiple meanings. Many in the field of natural sciences have been working on this problem of ambiguity—attempting to develop precise and powerful definitions. Still others argue that environmental quality is a concept open to societal negotiation (in addition to scientific discovery). In this thesis, I argue that environmental quality can be understood and discussed by examining understandings of Nature and evaluations for Nature that seem to contribute to the ambiguity of meanings and outcomes for environmental quality. To reach these conclusions, I interviewed 24 stakeholders who represented a broad range of concerns about and interests in environmental quality on private forest land in Southwest Virginia. I reviewed nearly 300 pages of interview text, looking for emerging themes and structures from their hour-long (on average) discussions of environmental quality. I found that among these 24 stakeholders, there were indeed, many ways of defining environmental quality (i.e. health, biodiversity, site productivity, et cetera). Additionally, I found that these different definitions for environmental quality seem to correlate with different understandings of Nature (what is Nature like?) and different values for Nature (how should Nature be used?) I conclude by discussing these implications, using examples from forestry outreach and extension. Master of Science

Environmental decision-making is a tournament of competing conservation agendas in which some values and beliefs are held up and exalted, others are dismissed and ignored, and still others are implicit and unnoticed. Stakeholders compete in the tournament to advance their value systems through the science they advocate or practice, through the constructs of environmental quality they use or study, and through the management goals they champion. It is our contention that participants who hope to compete successfully in this tournament should understand the rules of the game, which includes recognizing the values and ambiguities of the language used to discuss and describe nature - in particular the terms used to describe ecological conditions that become the goals and policies of forest management - and acknowledging the "middle nature".

Concern about water quality has become an important environmental issue in the world, the United States, and Virginia. Volunteers have increasingly stepped forward to assist in the water quality monitoring task, and both state and federal protection agencies increasingly depend upon such voluntary assistance. The Izaak Walton League's Save Our Streams (SOS) is one such volunteer citizen water quality monitoring program. Recruiting, training, organizing and retaining volunteers are among the most resource intensive tasks of volunteer organizations. The purpose of this thesis is to document the motivations of SOS volunteers and the primary causes of their attrition in order to improve the SOS program as well as to enhance the experience of SOS volunteers. We also compared motivations of SOS volunteers, differences in SOS volunteers' evaluation of the program, and suggestions for improvements by varying participation levels in volunteerism. We found that SOS volunteers are primarily motivated by a desire to protect streams and to improve water quality. Learning about streams and teaching these concepts to others were also important motivations. Volunteers cited not enough time and having too many other obligations as the main reasons why they stopped participating in SOS activities. Recruitment and retention of SOS volunteers may be aided by providing feedback about how volunteer data are being used by protection agencies to protect streams, and providing opportunities for learning about streams and teaching these concepts to others. Lastly, we found that those volunteers who were most active in SOS differed in their motivations for participating, tended to be the most critical of the services and materials, and were most adamant about their data being used to protect streams.

The overall objective of this study was to determine if remotely sensed data could be used to model scenic beauty. Terrestrial digital images from within forest stands located in Prince Edward Gallion State Forest near Farmville, Virginia were rated for their scenic beauty by a group of students to obtain scenic beauty estimates (SBEs). Since the inter-rater reliability was low for the SBEs, they were not used in the modeling efforts. Instead, stand parameters (collected on tenth acre plots) that have been used in scenic beauty prediction models, like mean diameter at breast height (dbh), were the dependent variables in regression analyses. A color-infrared aerial photograph from the National Aerial Photography Program (NAPP) was scanned to achieve a pixel ground resolution of one meter. The digital aerial photograph was rectified and used as the remotely sensed data. Since the aerial photograph was taken in April, only conifer stands were used in the analyses. Summary statistics were obtained from a 23 by 23 window around plot locations in three images: the original image, a texture image created with the variance algorithm and a 7x7 window, and the first principal component image. The summary statistics were used as the independent variables in regression analyses. The mean texture digital number for the green band predicted the mean dbh of a plot with an R2 of 0.623. A maximum of 44.3 and 27.4 percent of the variability in trees per acre and basal area per acre, respectively, was explained by the models developed in this study. It seems unlikely that the remotely sensed forest stand variables would perform well as surrogates for field measurements used in scenic quality models. Master of Science

Ecotourism and protected area visitation have been steadily increasing in recent years in Central and South America, inevitably resulting in natural resource impacts. The consequences of such impacts may include natural resource degradation, diminished aesthetic qualities, or decreased functionality of certain facilities like recreation sites and trails. Recreation ecology and visitor impact management expertise and tools are available to help balance the potentially conflicting management goals of protecting natural resources and permitting visitation but such knowledge has not been widely used in Central and South America. The goals of this research were to characterize certain visitor-related natural resource impacts and to determine how these impacts could be assessed and managed in Central and South America. The research included case studies of eight protected areas in Costa Rica and Belize, trail impact assessment research at Torres del Paine National Park in Chile, and development of a new visitor impact assessment and management framework, presented as three papers intended for journal submission. The first paper had two objectives: 1) to identify visitor-related natural resource impacts at selected protected areas in Costa Rica and Belize to increase awareness about visitor impact problems, and 2) to apply and compare rapid trail and recreation site impact assessment procedures to provide study site managers with impact data and impact assessment procedures. A variety of natural resource impacts were reported by interview subjects and recorded by rapid assessment procedures. The management utility of the rapid trail and recreation site impact assessment procedures were compared and discussed and the need for developing additional rapid assessment procedures to evaluate other resource impacts reported by protected area managers was also identified. The intent of the second paper was to investigate trail impacts at Torres del Paine National Park. Study objectives included measuring the frequency and magnitude of selected trail impacts, and comparing the relative impact contribution of the amount of use, vegetation type, trail position and trail grade on common condition indicators such as width and incision. Findings somewhat contradicted those of other studies, revealing that amount of use significantly contributed to trail width and incision. However, findings also indicated that vegetation type and trail grade contributed to number of informal trails and trail incision, respectively. A variety of management strategies were recommended and suggestions were provided for future monitoring studies. The purpose of the third paper was to propose a new visitor impact assessment and management framework that would provide managers with a feasible means of addressing visitor impact management concerns for selected protected areas in Central and South America. The Protected Areas Impact Assessment and Management (PAIAM) framework was adapted from existing frameworks like carrying capacity and the Limits of Acceptable Change to provide a simple, cost-effective and relatively quick decision making process. PAIAM analyzes visitor impacts using an expert panel and incorporates stakeholders and local residents into decision making. This study experimentally applied the new framework in Mexico and compared PAIAM to existing frameworks. The focus of this dissertation is on Central and South America since they are heavily visited ecotourist regions that could potentially benefit from applying recreation ecology and visitor impact expertise and tools to protected area management. This research demonstrated that a variety of visitor impacts are affecting natural resources and visitor facilities like trails and recreation sites at selected protected areas in Central and South America. This research also developed and applied rapid impact assessment procedures and visitor impact frameworks for use in Central and South American protected areas. Ph. D.

The purpose of this study was to analyze landowner perceptions of an ecosystem management program proposed by The Nature Conservancy. This creation of this program, The Forest Bank, is an attempt to protect the unique ecological and biological resources of the Clinch River Valley of Southwest Virginia. This study analyzed the attitudes and characteristics of landowners that contribute to their decision to enroll in such a program. Data were collected by a 8-page mail questionnaire sent to 2000 landowners in a five-county area of Southwest Virginia. The final sample size resulting from this effort was 816 landowner surveys, representing an overall response rate of 45%. Two separate analyses were undertaken with respect to this data, each representing a unique and informative approach to landowners and The Forest Bank. The first analysis summarizes how landowners perceived the individual components of the program, their level of interest in enrollment, and what types of landowners would be most likely to express interest in such a program. Twenty-three percent of landowners expressed interest in enrolling in The Forest Bank at some time. In general, those interested in enrollment perceived the individual components of the program differently than those who were not interested in enrolling. Landowners who expressed enrollment interest were more likely to be younger, more affluent, more educated than those who did not express interest in enrollment. The second analysis employed a structural equation model in order to determine what attitudes and motivations influence attitudes toward an ecosystem management program such as The Forest Bank. Variables such as attitudes toward property rights, environmental attitudes, trust in sources of information, and level of community attachment were included in this model. Results indicate that while attitudes toward property rights and the environment were not as important as previous literature suggested, landowner reasons for owning land were key indicators in determining attitudes toward The Forest Bank. Results from this study provide valuable information to managers and researchers concerning landowner attitudes toward ecosystem management and their level of interest in enrolling in an ecosystem management program. This information will help managers better understand how landowners perceive individual components of these types of programs, as well as determining the types of landowners who would be interested in enrolling. These findings can then be used to tailor programs that are more consistent with landowner objectives, and to better understand the complex attitudes and characteristics of private forest Master of Science

The purpose of this study was twofold: (1) to determine the extent to which boaters and riverfront landowners on the Great Egg Harbor River are similar or different in perceptions of environmental and social conditions and preferences for management; and (2) to explore factors that contribute to riverfront landowners' and visitors' opinions about possible management decisions for the river. The Great Egg Harbor River represents a complex challenge, with designation as a unit of the Wild and Scenic River system, overseen by the National Park Service, but ownership by twelve municipalities and hundreds of private landowners. Understanding similarities and differences between stakeholders is especially important in such a setting. Data were collected by on-site contact forms for boaters and a 12-page mailback questionnaire for both boaters and riverfront landowners. The final sample size for the mail survey was 428, representing an overall response rate of 44%. Boaters and landowners reported similar evaluations of general crowding and conflict, but landowners were significantly more sensitive to conflicts between boaters and landowners than were boaters. In terms of environmental issues, boaters were significantly more disposed to pro-environmental attitudes than were landowners. Landowners evaluated recreational developments more negatively than did boaters. With respect to management preferences, boaters and landowners did not significantly differ in their evaluation of increased law enforcement and actions that would restrict development and recreational use. On average, both groups supported these types of management actions. However, boaters and landowners significantly differed in their evaluation of management actions that provide additional river access. Although both groups generally opposed additional access, landowners were more opposed to these actions than were boaters. In addition, boaters were more supportive of visitor services than were landowners. Although classification as boater or landowner contributed to preferences for some management actions (increased law enforcement and additional river access), other variables were better predictors of these preferences. Pro-environmental attitudes contributed to preferences for increased law enforcement, restrictions on development and recreational use, and visitor services. Attitudes about development also influenced preferences for increased law enforcement and restrictions, but contributed to preferences for additional river access as well. Other explanatory variables included perceptions of general conflict and activity preference (motorized or non-motorized). These variables contributed to preferences for increased law enforcement and restrictions on development and recreational use. Results from this study indicate that managers need to better understand the correlates of management support in order to meet a more diverse set of visitor needs. Understanding the contribution of a variety of variables in management preferences will likely help resource managers better understand stakeholder groups and how they will respond to proposed management actions. Managers can use such information to better communicate river management goals, thus fostering more widespread constituency support for proposed actions. Master of Science

In light of the social construction of nature, "new" ecology, and the fact that neither nature nor science (as the systematic study of it) can tell us what the Earth should look like, it becomes evident that numerous (if not infinite) past, present and future natures exist from which society must select the nature or natures that become the goals of local environmental management. The challenge is to find themes or patterns that might help organize and discuss these many natures. It is not enough to say or to demonstrate that many natures exist. Society needs conceptual tools that help focus the discussion of "Which Nature?" on those that are possible and socially acceptable. This paper is an effort to identify and articulate some of these themes to see if they have power in helping structure public understandings of natural landscapes. Specifically, we are looking for natures that are evident in a larger national dialogue, reflect issues that are significant to the region where the nature being managed exists, and themes that have historic and place-specific qualities that can be found in local discourse about the place. Four different but closely related points of view fit this need: romanticism, ecotourism, pastoralism, and ecologism. These four "views of nature" are distinct and coherent "ways of seeing" evident in national, regional, and local discussions about nature and natural landscapes. Each promotes a unique range of "natural" conditions that will be more-or-less possible and acceptable in any particular place. In the following sections, I will first provide a general overview of the "natural" landscape of Whitetop Mountain and then describe how it is can be seen from each of the four alternative "views of nature."

Nonresident angler participation in Alaskan sport fisheries has increased at a higher rate than resident participation during the past decade. Popular sport fisheries have become crowded and stakeholder groups are increasingly concerned about the future direction of Alaska sport fisheries management. To address stakeholder concerns in an informed manner, the Alaska Department of Fish and Game (ADF&G) commissioned a market segmentation study to collect baseline information for assessing the impacts of projects and strategies that provide benefits to the angling public. I developed a 24-page mail questionnaire that was sent to a stratified random sample of 15,000 Alaska nonresident fishing license holders. Information was collected on fishing participation, fishing experience, activity-specific attitudes, motivations for fishing, as well as species and locations fished. In addition, information on setting preferences, guide use, fish exportation, and opinions on several management proposals was also collected. The response rate was 54% (exclusive of surveys that were undeliverable). A two-stage empirical clustering approach, employing Ward's method and UPGMA hierarchical clustering followed by k-means partitioning, identified five nonresident angler clusters. A combination of seven specialization and four motivation variables were used to identify angler groups. The angler segments ranged in size from 15% to 24% of the sample and had diverse characteristics including differences in frequency of participation, fishing experience and preferences, as well as motivations for fishing. Significant differences existed among angler segments with regard to Alaska fishing characteristics, such as number of days and locations fished in Alaska, number of fish transported from Alaska, attributes important in fishery site selection, and likelihood of returning to Alaska to fish. Differences in fishing characteristics, resource dependency, and preferences with regard to fishery attributes also were found among anglers participating in selected Alaska sport fisheries, as well as anglers fishing for different species within a fishery location (e.g., Kenai River). Information provided by this study will allow ADF&G to assess the relative nonresident demand for different types of angling experiences in Alaska, estimate nonresident angler response to potential management actions, and focus planning and management activities in ways that are consistent with the interests of these different angler types. Results also demonstrate the potential for fishery-based segmentation to provide fisheries managers with a more detailed understanding of nonresident angler participation at the regional and fishery level.

This study examines the concept of authenticity as applied at Appomattox Court House National Historical Park (ACHNHP). Based on past theoretical research, a functional definition of authenticity is used in an effort to test whether or not visitors to the park come for reasons relating to authenticity. Further analyses are used to determine the relative importance of authenticity to other motivational reasons for visiting the park, and how the level of authenticity experienced at ACHNHP affects how respondents rate the importance and performance of many park setting attributes. Using motivation for authenticity and importance/performance variables as predictors, visitor knowledge, perceptions of crowding and conflict, and overall satisfaction are assessed. The results suggest that while authenticity is important for park visitors, experience outputs are difficult to forecast because of correlation among independent variables and homogeneity of park visitors. Recommendations are made for future researchers when examining the concept of authenticity. Master of Science

I surveyed members of the Rocky Mountain Elk Foundation (RMEF) and the Appalachian Trail Conference (ATC) to assess the motivations of active and nonactive memebrs in these nongovernmental organizations (NGOs). I investigated the effects of social networks, competing commitments, requests for participation and the belief of the efficacy of their actions on decisions to become and remain active members. I found that requests are important tools for recruiting new members but not the determining factor in the decision to participate. Rather, in both NGOs, active members indicated that the efficacy of their actions was most important in their decisions, while nonactive members cited the importance of competing commitments. I also investigated what leads to burn out and attrition of active members. Burn out and attrition in active members often resulted from a lack of personal satisfaction and growth from contributions. Active members who had experienced burn out donated more hours, had been members and active longer, and in the RMEF needed more recognition than those members who had not experienced burn out. Volunteers who discontinued participation also cited age, health, and personal reasons, Recruitment and retention of volunteers may be aided by increasing the awareness of volunteer programs, ensuring the programs provide results that individuals are proud of, requesting the participation of individuals on both local and higher organizational levels, and recognizing volunteers for their contributions.

It is generally recognized that the magnitude of recreation resource impacts should be judged by their severity and spatial qualities, including extent, distribution, and association. Previous investigations, however, have primarily focused on assessing the severity of impacts, with limited examination of spatial qualities. The goal of this dissertation was to expand our understanding of the spatial dimension of recreation resource impacts and their assessment and evaluation. Two empirical data sets collected from a comprehensive recreation impact assessment and monitoring project in Great Smoky Mountains National Park provided the basis for the analyses. Three spatial issues were examined and presented as three papers, designed for journal submission. The purpose of the first paper was to improve our understanding of the dimensional structure and spatial patterns of camping impacts by means of multivariate analyses and mapping. Factor analysis of 195 established campsites on eight impact indicator variables revealed three dimensions of campsite impact: land disturbance, soil and groundcover damage, and tree-related damage. Cluster analysis yielded three distinctive campsite types that characterize both the intensity and areal extent of camping impacts. Spatial patterns and site attributes of these three campsite types and an additional group of primitive campsites were illustrated and discussed. The purpose of the second paper was to examine the influence of sampling interval on the accuracy of selected trail impact indicator estimates for the widely applied systematic point sampling method. A resampling-simulation method was developed and applied. Simulation results indicated that using systematic point sampling for estimating lineal extent of trail impact problems can achieve an excellent level of accuracy at sampling intervals of less than 100 m, and a reasonably good level of accuracy at intervals between 100 and 500 m. The magnitude of accuracy loss could be higher when the directions of loss are not considered. The responses of accuracy loss on frequency of occurrence estimates to increasing sampling intervals were consistent across impact types, approximating an inverse asymptotic curve. These findings suggest that systematic point sampling using an interval of less than 500 m can be an appropriate method for estimating the lineal extent, but not for estimating occurrence of trail impacts. Further investigations are called for to examine the generalizability of these results to other areas. The purpose of the third paper was to expand the scope of indices used for evaluating recreation resource impacts. Two specific objectives were to synthesize the recreation ecology and recreation resource management literature on the use of spatial indicators and indices, and to propose and apply selected spatial indices that are mostly lacking in the literature. Three spatial indices primarily adapted from the geography and ecology literature were proposed for application in recreation impact evaluation. Application results demonstrated that the Lorenz curve and associated Gini coefficient, and the linear nearest-neighbor analysis and associated LR ratio were effective in quantifying the spatial distribution patterns of trail impacts at landscape and trail scales, respectively. Application results of the third index, the impact association index, were less promising and require further refinements. Management implications and future directions of research were discussed in light of the findings of this dissertation. As the field of recreation ecology is emerging, this dissertation has demonstrated: (1) the value of recreation impact assessment and monitoring programs in providing data for examining the spatial dimension of impacts, and (2) the utility of spatial analytical approaches in understanding recreation impact assessment and evaluation.

Depreciative behavior is a significant problem facing natural resource managers. The theft of petrified wood from Petrified Forest National Park is one type of depreciative behavior. Despite numerous anti-theft interventions, approximately 12 tons of wood disappear from the park each year. The focus of this study was to design, implement, and evaluate the effectiveness of interventions to reduce the theft of petrified wood. In addition to gaining a quantitative measure of intervention effectiveness, qualitative interviews were conducted to provide some contextual understanding of wood theft and of designed intervention effectiveness in reducing theft. Tested interventions included a sign, a signed pledge, and a uniformed volunteer. A field experiment revealed a theft rate of 2.1 % under the control condition. All three interventions significantly reduced the theft rate to about 1.4 %. There was no difference in the effectiveness of the three tested interventions. Subjective responses revealed that most theft was not a thoughtless act, but instead occurred because thieves rationalized their particular act of theft as acceptable. The primary rationalization given by thieves was that their piece of stolen wood was so small that taking it would not hurt anything. It appeared as though anti-theft messages were received by most of those interviewed, but that thieves only applied these messages to the larger pieces of wood. In addition, most thieves did not view taking a little chip as stealing. Interviews suggested visitors attended to the following aspects of the interventions: the desired behavior itself, the negative consequences of theft behavior, the visitors' responsibility for those consequences, the sanctions involved for the behavior, and visitors giving their word not to steal any wood from the park.

The purpose of this study was to understand the relationships between participation in park interpretive programs and attitudes, norms and behavior about theft of petrified wood at Petrified Forest National Park (PFNP). The Theory of Reasoned Action guided the research. Data collection included observation of theft behavior, on-site interviews and mailback questionnaires. Findings indicated that more time spent at interpretive centers and programs did not result in visitors; attitudes and norms about individual acts of wood theft being more negative. Also, attitudes and norms about petrified wood theft did not vary by type of interpretive programs judged most helpful in learning the park;s story and in learning the park;s rules and regulations. Tentative evidence suggests that the norm against taking a handful of wood was stronger among individuals who cited visitor centers as their most helpful source than it was for respondents who said the same about other national park interpretive programs. Similarly, the attitude variable that it is all right to take a piece of petrified wood as long as it is a small piece did vary for two categories of interpretive programs (other national park programs and all ranger programs). Ranger programs measured significantly higher than other national park programs. The rate of theft of petrified wood was not inversely related to the amount of interpretive programs participated in and did not vary by type of interpretation judged most helpful. Finally, attitudes and norms about petrified wood theft did not shape theft behavior. However, knowing visitors; attitudes helped to predict who would be a non-thief. Master of Science

This dissertation examines four issues, including: (a) whether outdoor recreation experiences not included in the Recreation Experience Preference (REP) scales exist; (b) whether these experiences can be categorized using a framework called the Recreation Experience Matrix (REM); (c) how well the Recreation Opportunity Spectrum (ROS) variables of activity, setting, and expertise explain the types of experiences outdoor recreationists receive; and (d) how well two new variables--primary mode and mode dependence--explain the types of experiences outdoor recreationists receive. In order to address these issues, an on-site questionnaire was distributed at Mount Rogers National Recreation Area in Virginia during October and November, 1995 A total of 410 people completed this questionnaire. Of these, 336 provided useable addresses for a follow-up mail-out questionnaire, with 169 (50.3%) actually returning it. After performing a variety of statistical analyses, it was found that: (a) some outdoor recreationists did report having non-REP experiences involving identity, cognition, absorption, and self-concept; (b) indirect support does exist for classifying outdoor recreation experiences using the REM framework; and (c) the ROS variables of activity, setting, and expertise, do explain some outdoor recreation experiences, as do the new variables of primary mode and mode dependence.

This study examined the influence of Iocational factors on offender behavior in four serious and common park offenses: auto burglary, drug sales, indecent exposure by homosexual males, and robbery. Specifically, the study sought 1) to develop prototypical script(s) for each of the four study crimes, and 2) to support or contradict the influence of effort, risk and reward on offender behavior. Using the theoretical bases of opportunity, rational choice, and scripts, behavior of study offenders in 6 U.S. Park Service reservations in Washington, DC was interpreted. A case study strategy was chosen, utilizing participant observation, direct observation, archival records, physical artifacts, and interviews. Data collection occurred between January and March, 1996, with law enforcement personnel serving as the primary information source. Following qualitative analysis that relied upon pattern-matching and explanation-building, results suggested that 1) offenders follow logical sequences of behavior consistent with concept of a script, 2) offenders were found to act rationally, appearing to consider effort, risk and reward, 3) that offenders weight the importance of effort, risk and reward differently across offense types and across the different Acts of the same offense script, 4) that Iocational factors do influence the behavior of offenders, and 5) that offenders utilize Iocational factors that serve to decrease effort and risk, and increase reward.
