For more than 100 years, the Unite States National Park Service (NPS) has been guided by a mandate to preserve parks and their resources for the enjoyment of present and future generations. But all parks are subject to conditions that may frustrate preservation efforts. Climate change is melting the glaciers. Rising seas are sweeping away protected shorelines. Development projects, accompanied by air, water, light, and noise pollution, edge closer to parks and fragment habitats. The number of visitors and vested interests are swelling and diversifying. Resources for preservation, such as funds and staff, seem to be continuously shrinking, at least relative to demand.

Still, the NPS remains committed to the preservation of our natural and cultural heritage. Yet the practice of that promise is evolving, slowly and iteratively, but detectably. Through explorations of legal and scholarly literature, as well as interviews across the government, non-profit, and academic sectors, I’ve tracked the evolution of preservation in parks. How is preservation shifting to address socio-ecological change? How has preservation evolved before? How should the NPS preserve parks moving forward?

The practice of preservation has come to rely on science, including partnerships with academic researchers, as well as inventory and monitoring programs. That shift has in part been guided by goals that have also become more informed by science, like ecological integrity. While some interviewees see science as a solution to the NPS’s challenges, others wonder how applying science can get “gnarly,” due to uncertainty, lack of clear policies, and the diversity of parks and resources. “Gnarly” questions stem in part from the complexity of the NPS as a socio-ecological system, as well as from disputed, normative concepts that underpin the broader philosophy of preservation, including naturalness. What’s natural in the context of pervasive anthropogenic change? Further, I describe how parks hold deep, sometimes conflicting, cultural and symbolic significance for their local and historical communities and for our nation. Understanding and considering those values is part of the gnarly task park managers face in their mission to preserve parks. I explain why this type of conceptual and values-based uncertainty cannot be reduced through science.

The United Nations projects that 68% of the world population will live in urban areas by 2050. As urban areas continue to grow, it is critical to consider how cities will be redesigned and reimagined to ensure that they are healthy and beneficial places that can properly support their residents. In addition, college students have been identified as a vulnerable population in regards to overall wellness. In Downtown Phoenix, one the biggest elements of concern will be the built environment and its influence on wellbeing as the city itself and Arizona State University’s Downtown campus populations continue to expand. Given this, the purpose of this study is two-fold. I applied Social-Cognitive Theory as a framework to first, understand student perceptions of the built and social environment and second, explore how perceptions of the built and social environment influence student wellbeing. I used semi-structured interviews and participant-driven photo elicitation to answer these questions. The study took place at Taylor Place Mall on Arizona State University’s Downtown Campus and participants were students who attend classes on the ASU Downtown Campus. Findings displayed the need for design considerations to focus on the safety of students, creating places to gather for social connection, and overall a desire for design to focus on place making and place meaning, as well as other themes. Understanding more clearly how the built and social environment guides behaviors and social opportunities can help urban designers, landscape architects, and community developers better plan healthier environments that foster productive behaviors, create meaningful spaces, and prove to be sustainable in future years.

The national parks are often considered to be one of America’s greatest achievements. Through a rich and sometimes tumultuous history, the national parks have been shaped from unwanted swaths of land into some of the most famous landscapes in the country. There are ultimately two conflicting goals of the national parks: provide enjoyment for the American people and protect the land. In recent years, increased popularity of the parks has made achieving these dual goals particularly difficult. Crowding in the parks leads to both ecological and social problems that threaten both goals of the national parks. Crowding is a multifaceted issue that must be explored from multiple perspectives.

Using Zion as a case study, the problems of crowding are explored and evaluated. First the history of the national parks is described to determine how the parks were created and popularized. After exploring the history of the parks, crowding in the national parks will be
discussed, including an overview of some of the significant social science literature exploring
crowding and its impact on visitor experience. This analysis will conclude with an examination
of visitor management strategies and an examination of the park-specific literature about the specific problems and decisions confronting managers at Zion National Park. A personal account of a visit to Zion during the peak season will provide a personal narrative about the meaning and purpose of the park experience.

The final section of this thesis will consider a range of opposing views on the philosophy of national parks and the park experience, centering around the ideas of Abbey, to address the deeper questions surrounding the goals of park management as we likely more toward an even more crowded park future. Ultimately the paper concludes that the parks has shifted irrevocably away from the ideals of Abbey, although his voice still provides inspiration to generations of park lovers. Additionally, while hard limits must eventually be set, in an era of increasing human influence, the park experience will need to be redefined to be more expansive and inclusive of all who wish to visit and enjoy.

Trails perform an essential function in protected lands by routing visitors along planned, sustainable surfaces. However, when visitors deviate from official trails in sufficient numbers, it can lead to the creation of social trails. These visitor-created pathways are not sustainably designed and can severely degrade both the stability and appearance of protected areas. A multitude of recreation motivations among visitors and a lack of resources among land management agencies have made the mitigation and closure of social trails a perennial concern. A sustainable, economical strategy that does not require the continual diversion of staff is needed to address social trails. In this study, two techniques that stand out in the research literature for their efficacy and practicality were tested on a social trail closure in South Mountain Park, a high-use, urban-proximate mountain park in Phoenix, AZ. A research design with additive treatments utilizing the site management technique known as trail mitigation, sometimes referred to as brushing in the literature, followed by theory-grounded signage incorporating injunctive-proscriptive wording, an attribution message, and a reasoning message targeting visitor behavioral beliefs, norms, and control was applied and assessed using unobtrusive observation. Both treatments reduced observed off-trail hiking from 75.4% to 0%, though traces of footsteps and attempts to re-open the trail revealed the existence of unobserved “entrenched” users. With entrenched users attempting to reopen the trail, trail mitigation represented an effective but vulnerable approach while the signage represented a long-lasting “hardened” approach that provides an educational message, management’s stance on the closure, and which might put social pressure on the entrenched user(s).

For the last 10 years, the American Southwest has been experiencing the most persistent drought conditions on record. Based on future climactic predictions, there is a dire need to reduce water usage within Phoenix. An environmentally responsible behavior such as low water use landscaping (xeriscaping), has been shown to reduce household water consumption by 40%-70%. While much is known regarding the relationship between socio-demographics and xeriscaping choices, the influence of other variables remains to be explored. Using data from the 2017 Phoenix Area Social Survey, this study investigates the influence of two additional variables - ecological worldview and place identity on xeriscaping choice. Data was analyzed using two models - Ordinary Least Squares (OLS) and Linear Probability Model (LPM). Ecological worldview and place identity, along with income, ethnicity, and gender, were all found to be positively related to xeriscape preference. Additionally, when compared to the LPM, the traditional OLS was found to still be the most robust and appropriate model when measuring landscape preference. Finally, results suggested that programs to foster identity with the local desert mountain parks may help to increase xeriscaping in the Valley and thus lower residential water use.

Denver, Colorado is experiencing an unprecedented growth spurt, particularly in the downtown neighborhoods. As such, the city has proposed a multitude of urban revitalization projects in its urban core. This pattern of revitalization has unintended consequences including changes in residents’ meanings assigned to their neighborhoods and subsequently changes in residents’ attachment to those neighborhoods. Given this, the purpose of this phenomenological study was to use a symbolic interactionist perspective to uncover resident meanings of their neighborhoods and discover how redevelopment efforts are affecting those assigned meanings. Participants, recruited through the snowball sampling method in the Globeville and Elyria-Swansea neighborhoods in downtown Denver, were interviewed during spring of 2017. Photo-elicitation techniques were used as part of the interviews. Additionally, secondary data available through public documents were analyzed to provide a context for understanding the changes that are taking place in the selected neighborhoods. This data aids in guiding future research, which may ultimately better inform the government agencies and private organizations who are looking to redevelop low-income neighborhoods similar to the Globeville and Elyria-Swansea neighborhoods in the given study.

Current conservation practices are substantially biased towards large, charismatic animals and are influenced by public perceptions of different animals. Therefore, it is important to understand how these perceptions are formed and what factors influence them in order to promote equitable conservation for all species. This study examines the effect of attending a park education program on public values, knowledge of, and attitudes towards a noncharismatic species. Data was collected from May through October 2016 at the Usery Mountain Regional Park "All About Scorpions" program. A four page, onsite, self-administered pre- and post-program survey was given to program attendees. An identical survey was given to hiking park visitors who had never attended the program as the control sample. Survey statements addressed participant's demographics, value of bugs, knowledge about scorpions, and attitudes toward scorpions. Data analysis was completed using paired t-tests to analyze any statistically significant changes in values, knowledge, and attitudes between pre- and post-participants. Independent sample t-tests were used to analyze the same between the control and pre-participants. The results showed no difference in the value of bugs for any of the survey participants. However, the program attendees had more positive attitudes and greater knowledge of scorpions than general park visitors, and attending the program further increased positive attitudes and knowledge. Contributions of the study are twofold: First, the results provide Usery with information regarding the influence of their public programs, along with how these programs can be improved to make a greater impact. Second, findings serve to extend the literature on what alters public perceptions and how educational programs can be used to change the current conservation mindset.

Issues of visitor safety are a concern among park and recreation managers. As urban parks receive a variety of user groups, understanding perceptions of safety among specific groups becomes pertinent when managing for optimal experiences. This study examines trails runners at two mountain parks in a large southwestern city. Data was collected in the fall of 2013 and the spring of 2014 using a five page, onsite, self-administered, exit survey in English. Questions addressed trail runner demographics, level of trail running experience, perceptions of safety, and support for safety related management actions. Of specific interest was how perceptions of safety varied by trail runner demographics and level of experience. 102 trail runners participated in the study. Data analysis was completed using an independent samples t-test to compare sample characteristics with perceptions of safety and safety related management actions. The results include mixed opposition and support for specific preventive management actions. Few significant differences in responses were found between gender, age and specialization. The findings also suggest trail runners primarily learned about these recreation areas through local knowledge and "word of mouth" and not through managers. Further implications of these finding is discussed. Contributions of the study are twofold. First, results provide managers with information regarding trail runners at the parks. Second, findings serve to extend the literature on visitor safety at park and recreation settings in urban areas.

Increasingly, wildfires are threatening communities, forcing evacuations, damaging property, and causing loss of life. This is in part due to a century of wildfire policy and an influx of people moving to the wildland urban interface (WUI). National programs have identified and promoted effective wildfire mitigation actions to reduce wildfire risk; yet, many homeowners do not perform these actions. Based on previous literature and using the theory of planned behavior (TPB), this study proposes an integrated wildfire mitigation behavioral model to assess and identify the factors that influence homeowners’ wildfire mitigation behaviors. Specifically, the study tests the validity of the theory of planned behavior as a foundational model in exploring wildfire mitigation behaviors, develops and empirically tests a wildfire mitigation behavioral model, and explores the role of homeowner associations (HOA) on wildfire mitigation behaviors. Structural equation modeling was used on data collected from homeowners with property in the WUI in Prescott, Arizona. Results suggest TPB provides an acceptable model in describing homeowner wildfire mitigation behavior. For HOA residents, attitudes toward wildfire mitigation behaviors play an important role in predicting intentions to perform these behaviors. Additionally, perceived constraints directly influenced actual mitigation actions. For non-HOA residents, subjective norms influenced intentions to mitigate. Implications for research and local wildfire mitigation programs and policy are discussed.

Recent research within the field of natural resource management has been devoted to studying the cognitive structures, called mental models, that guide people’s thoughts, actions, and decision-making. Artificial lighting threatens the sustainability of pristine night skies around the world and is growing worldwide at an average rate of six-percent per year. Despite these trends, stakeholders’ mental models of night skies have been unexplored. This study will address this gap by eliciting stakeholders’ mental models of dark skies. Scenario planning has become a pervasive tool across diverse sectors to analyze complex systems for making decisions under uncertainty. The theory of scenario planning hypothesizes that scenario planning contributes to learning and improves upon participants’ mental models. However, there have been scant empirical studies attempting to investigate these two claims. Stakeholders’ mental models of dark skies were mapped while simultaneously testing the hypotheses that participation in scenario planning results in more complex mental models and alters environmental attitudes. Twenty-one Arizona stakeholders participated in one of two workshops during September 2016. Three identical surveys were given to measure knowledge, environmental attitudes and mental model change during the workshops. Knowledge gain peaked during the introductory lecture and continued to increase during the workshop. Scenario planning increased participants’ environmental attitudes from anthropocentric to nature-centered and was found to have a significant positive impact on dark sky advocates’ change in mental model complexity. The most prominent drivers affecting dark skies were identified using social network analysis of the pre and post mental models. The most prominent concepts were altered significantly from pre to post workshop suggesting that scenario planning may aid practitioners in understanding exogenous factors to their area of expertise. These findings have critical theoretical and managerial implications of mental model alteration, environmental attitudes, and the future of Arizona’s night skies. A revised theoretical framework is offered to include environmental attitudes into the theory of scenario planning and a conceptual framework was created to illustrate the most salient drivers affecting or being affected by dark skies.
