Master of Landscape Architecture / Landscape Architecture/Regional and Community Planning / Howard D. Hahn / The absence of participation in physical activity is a public health concern for all people, but even more of a problem for the estimated 52 million Americans with disabilities (Rimmer 2005). Besides the physical health benefits derived from physical activity, when a trail leads through a natural setting, research shows that significant sensory and cognitive benefits can also be gained which leads to greater well-being (Maller et al. 2005; Hull and Michael 1995; Kaplan 1995; Irvine and Katherine 2002). Furthermore, when trails are planned and constructed in natural settings, most of the attention is directed at minimizing environmental impacts at the exclusion of maximizing the physical, sensory, and cognitive experience of users. This shortcoming is compounded when the user has disabilities. Besides typical disability concerns related to mobility, disabilities to be better accommodated in trail design also include vision and hearing impairments. The focus of this research is investigating how trail planning and design in natural settings can better provide for the physical, sensory, and cognitive experience of users, particularly those users who have disabilities. Findings informed the development of Natural Trail Design Guidelines prepared for the City of Manhattan Parks and Recreation Department who is seeking to improve the City’s existing natural trails. Sample designs for trail enhancements at Anneberg Park and the Konza Prairie near Manhattan, Kansas were proposed. Once implemented and assessed to be found successful, the Natural Trail Design Guidelines might be transferable to other locations.

As population increases, the need for public recreation facilities and resources increases. The U.S. Forest Service, National Park Service, and other recreation providers are constrained by limited time and funding to plan for, and implement, recreational facilities for the areas that they serve. Poorly located and designed recreational trails increase maintenance costs, resource degradation, and the inefficient utilization of public resources. The potential application of Geographic Information Systems (GIS) technology to this specific type of problem is examined through the comparison of hypothetical trail routes generated by several different methods, existing trail field surveys, office design, GIS user-assisted design, and cost-path analysis design. Each method is compared statistically and qualitatively by GIS methods and office based methods. Each hypothetical trail is ranked according to effectiveness of design, providing insight into trail design methods. The office designed hypothetical trails were consistently ranked highest by an expert forest road designer. / Master of Science

Visitor activities in parks often have a heavy impact on the soil, vegetation, water and wildlife. In front country areas, the most extreme damage is concentrated on and adjacent to recreational trails. Aside from controlling the numbers, activities and behaviours of trail users, managers may choose to make trails more resistant to impact through surfacing. Unfortunately, surfacing may have negative influences on park visitors' enjoyment of trails by limiting access or detracting from the primitive setting. In addition, some surfaces may be ineffective in certain environmental conditions such as wet ground or steep slopes. Finally, the wide variety in construction and maintenance costs may make some surface types economically unfeasible. The goals of this research are to investigate the role of trail surfacing in the management of impacts from outdoor recreation; to develop better understanding of the social, economic and environmental aspects of trail surfacing decisions; and to explore a comprehensive framework for incorporating these three factors in trail management. It is hoped that this research can assist park managers in selecting surfacing options to reduce visitor impact without excessively compromising recreational experience or organizational limitations, such as financial resources. In addition to a comprehensive review of literature on visitor impact management on trails and surfacing techniques, this research employs three methods to further investigate the social, environmental and economic aspects of trail surfacing: a trail user survey, manager survey and trail condition assessment. The trail user survey was conducted at two well-used natural areas in southwestern Ontario, Canada: Presqu'ile Provincial Park and Belfountain Conservation Area. Surveys at each area explored trail users' perceptions and preferences of trail surfacing techniques in late summer 1999. The managers' survey provided insight into organizational approaches to surfacing, including construction cost and observations on recreational or environmental effectiveness. Finally, the trail condition assessment explored an approach to determining environmental effectiveness of trail surfacing techniques, but was limited by the physical and recreational variation between trails. Seven recommendations for trail managers are presented, tying in several conceptual frameworks of visitor impact management and trail surfacing decisions developed in the thesis. First, trail managers are recommended to develop a full understanding of trail design principles and alternative visitor impact management techniques. If surfacing is selected as the best impact management technique, trail managers should obtain as much information on user characteristics, environmental conditions and organizational limitations as possible. Despite the benefits and drawbacks for all surfaces, road base gravel (or angular screenings with fines) merits special attention as an excellent surface, while asphalt and concrete are not recommended for front country, semi-primitive recreation. Finally, trail managers are encouraged to share information on surfacing more freely and open surfacing decision processes to affected trail users. Overall, trail managers are provided with an approach to surfacing decisions that considers the social, environmental and economic aspects of trail surfacing, with the goal of working toward more enjoyable, environmentally responsible and cost-effective trail solutions.

In addition to their original purpose as recreational areas, urban parks provide important habitats for species living in urban settings. Reconciling recreational and environmental goals is problematic, especially for park planners. RIM Park, in Waterloo, Ontario, is an example of this attempted reconciliation, where planners and managers attempted to conserve herpetofauna in a provincially significant wetland. However, this area includes a paved nature trail used by hikers, in-line skaters and cyclists and is adjacent to a golf course (which lies within the boundaries of the park). Herpetofauna breeding ponds were constructed and a series of culverts and clearspans included in order to provide reptiles and amphibians with safe passage under the trails. My objective was to determine whether these measures have been effective, whether the park sustains a viable population of Northern Leopard Frogs, and what factors influence frog populations in the park. Two spring field seasons involving mark and recapture techniques were attempted to estimate population sizes of Northern Leopard Frogs at RIM Park, as well as control sites. In both seasons, a control site was a cedar swamp 14 km to the west of the park within an Environmentally Sensitive Policy Area in Waterloo city limits affected by housing development and shared trails. Also within Waterloo city limits, a storm water management pond 8 km to the west was added in field season two. In 2005 (field season 1), because there was a serious drought almost no Northern Leopard Frogs were captured at the two sites examined ? RIM Park and the cedar swamp. In 2006, the more "normal" weather conditions revealed that RIM Park had significantly fewer Northern Leopard Frogs than either of the control sites. Given the lack of data in year 1, I compared the 2006 results to seven years of monitoring reports on RIM Park from consultants. The 2006 data were consistent with previous reports of small Northern Leopard Frog populations at RIM Park. Mark and recapture sessions revealed relatively low numbers, with a catch average of 4. 33 (SD = 1. 15). Calculations revealed an estimated population of 23 (SE = 13. 42). The highest number of observed Northern Leopard Frogs ever recorded at the same location in consulting reports is 5. It is likely that the ponds at RIM Park do not support breeding in Northern Leopard Frogs as the only adults caught were late in the season, during the last week of May, and adults likely were transients from the nearby wetlands and uplands. It is possible, given the historical monitoring data, that the Northern Leopard Frogs were long absent from RIM Park because of intensive farming activities that had replaced the wetlands, and that construction of the golf course and trails further precluded colonization. The lack of adult frogs in the breeding ponds and the lack of dead or injured frogs on the trails or golf course support the hypothesis that the trails are not presently causing frog mortality. It is possible that the frogs are avoiding recolonizing the trail and golf course area. It is also likely that the breeding ponds need to be deepened and only then will it be apparent whether the frogs will colonize the ponds, lay eggs, and use the clearspans and culverts. Recommendations include a shift in priorities to put the emphasis on restoration, a discussion of restoration options (including a possible restoration plan), possible improvements in amphibian monitoring techniques (such as reducing the reliance on audio methods), and general suggestions for urban park planning and management.

This paper examines the topic of memorial design and experiential landscapes, emphasizing the role of memorials as spatial expressions of culture, history, memory, life, and death. Memorials have traditionally been monumental in form, but there is a growing shift in landscape architecture towards designing experiential memorial landscapes that allow for healing, reflection, and active participation. This progression in design highlights the landscape's role in preserving memories of tragedy and fostering a deeper connection between users and the land. This project focuses on the design of a memorial for the St. Francis Dam Disaster, a catastrophic event in California that reshaped the landscape and the lives of those affected. This project explores how a post-disaster site can be transformed into an experiential memorial landscape that tells the story of the past, present, and future landscape, creates a site pilgrimage through strategic memorial design, and reveals the profound impact of the tragedy on the land. Studies of memorial design principles and case studies focused on trail systems, site programming, and landscape aesthetics guided the design work. Design guidelines and design study processes developed through this research exemplify how to approach an experiential memorial design and challenge designers to approach and adapt their designs to complement existing landscape conditions. / Master of Landscape Architecture / This paper explores how to design a memorial for the St. Francis Dam Disaster, a catastrophic event in California that altered both the land and the lives of those affected. A memorial is different from a monument because it focuses more on the visitor's experience within the space. Drawing on established memorial design guidelines and similar landscape architecture projects, this project creates a memorial that enhances the visitor's experience and educates the visitor on existing elements in the surrounding landscape. This project engages with existing research and establishes a way of approaching a large-scale memorial design that will be beneficial to the field of landscape architecture.

This research investigates the influence of layout and design on the severity of trail degradation. Previous trail studies have been restricted by relatively small study areas which provide a limited range of environmental conditions and therefore produce findings with limited applicability; this research improves on this limitation by analyzing a representative sample of the Appalachian Trail with significant ecological diversity. Most trail science studies have also focused on a singular form of trail degradation, whereas this study investigates trail soil loss, widening and muddiness, providing a more cohesive analysis and revealing interrelationships between trail degradation processes. ANOVA testing of the mean values of three trail impact indicators for trail transects within several trail layout frameworks confirms the broad relevance of core trail design principles, specifically the sustainability advantages of trails with low grades and side-hill alignments. Findings also reveal the importance of landform grade in determining the susceptibility of trails to degradation and the influence of routing decisions; these relationships have received relatively little attention in the literature. The results also reveal several methodological considerations for trail alignment metrics and trail impact indicators. / Master of Science / Natural surfaced trails are an essential infrastructure component in parks and protected natural areas. They provide transportation routes through otherwise undeveloped areas and outdoor recreation opportunities for hikers, mountain bikers, and equestrians. Over time, recreational use and natural processes such as rainfall can lead to negative ecological impacts that damage trail treads in ways that impair their utility for visitors and require costly repairs. Environmental factors like unstable soils or extreme precipitation can make trails more susceptible to degradation. However, sustainable trail layouts and effective maintenance can reduce the rate and severity of degradation. This research investigates the influence of trail layout on three chief forms of trail degradation: trail soil loss, muddiness, and widening. Many trail science studies have occurred in small protected natural areas where the limited range of represented environmental conditions reduces the applicability of their findings in dissimilar settings. This study investigates a dataset from a large and ecologically diverse representative sample of the entire Appalachian Trail from Georgia to Maine which significantly broadens the relevance of its findings. Furthermore, many previous trail studies have focused on single forms of trail degradation whereas this study which investigates three, which provides a more cohesive analysis and reveals interrelationships between impacts. Findings confirm the broad pertinence of core sustainable trail design principles, specifically the benefits of low trail grades and side-hill alignments, and suggests that landform grade is an important factor which has received little attention in the literature. The study also revealed several methodological improvements and considerations which may be useful to trail scientists and practitioners.
