Woody ornamental plants are considered the key for well- designed landscapes; Callistemon citrinus is one of those plants. In arid and semiarid areas, Callistemon has been used in gardens and landscapes for its unique characteristics. This study was conducted to evaluate the performance of Callistemon in landscapes under different environmental stress conditions including water, and heat. Further, the potential of using 3D software SketchUp in landscape design was also investigated. Callistemon plants were grown under 100, 50 or 30% of field capacity with or without shredded hardwood mulch. When field capacity decreased, root: shoot ratio and water use efficiency were improved, but canopy temperature increased. The decreased water caused decreases in leaf greenness, chlorophyll a, shoot volume, root volume, leaf water potential, and transpiration rate. Mulch increased root volume and leaf water potential. Callistemon growth under shade structure angle and orientation was examined. Shade structures were installed at 90° and 70° to the ground and three orientations, south, east, and west. Transpiration rate was reduced under the shade. The plant’s response to heat was also examined. Plant were exposed to 45/35, 35/25, or 25/15 °C, d/n. The plant’s physiological response was tested after two weeks. Highest temperatures decreased Chl b content and SOD activity compared to control. In contrast, carotenoid content and H2O2 level increased under the highest temperature treatment. Catalase activity was increased at moderate but decreased under the highest temperatures. Designing a 3D model using SketchUp software was examined. The program function was evaluated, and the designed experiment was tested. Planning a site with shadows predicted was achieved. The work was done with greater precision and less effort. The program was effective in reducing time and cost. SketchUp can be successfully used in landscape work.

This thesis is a qualitative study of current teaching practices in landscape architecture centering around instructors' understanding and use of studio teaching methods. Selected faculty, considered by their peers to be expert studio instructors, participated in one hour, open-ended interviews sing their instructional experiences and examining the teaching methods they espouse. The resulting transcripts provided a base for qualitative analyses for a small sample of current teaching practices. By documenting selected design studio instruction methods, new faculty may draw upon a pool of education possibilities ranging far beyond their experience as students. Similarly, examination of the theoretical foundations, expected outcomes, and teaching methods of professors may provide new faculty with a more holistic benchmark for gauging their professional growth. / Master of Landscape Architecture

Owing to the author's interest in and concern for earth's processes, healthy ecosystems, and environmental decline and devastation, this thesis examines the human – nature relationship, as it relates to landscape architecture, through spiritual, mathematical, geometrical, historical, economical, ecological, philosophical and ethical perspectives. Sustainable design and eco-revelatory design methods are also explored in order to aid in the development of a personal design ethic that defines and produces ecologically responsible works of landscape architecture. The goal is to establish a personal framework for design that results in built landscapes that are ecologically more benign, holistically more functional, and culturally more significant than standard practices. Research methodologies include literature review, case study analysis, project site analysis, and personal interviews. Findings suggest that despite a longstanding and growing call for a more harmonious relationship between nature and anthropogenic changes on the land, the green movement remains a loosely defined alternative undercurrent. The field of landscape architecture is uniquely poised to be a leader in the sustainable revolution; this is especially true when its practitioners, researchers and theorists are dedicated to ideals and activities that bring about true ecological value. For the individual designer, the experience of developing and committing to a personal design ethic can be empowering, and can produce work that has more mettle, veracity and purpose than the designer has previously known. / Master of Landscape Architecture

The research presented in this thesis is intended to reveal the layers of social and cultural meaning invested in a building conventionally regarded as a work of abstract aesthetic modernism, and one which has been evaluated, within the framework of a national heritage preservation policy, as an architectural landmark of the post-war era of urban reconstruction. By combining the research methods of architectural history (archival) and of anthropology (ethnographic) I have located and interpreted the architecture of the Brunswick within a larger social story that demonstrates how the lived experience of a particular environment exists in parallel with the more objective official discourse that invests a work of architecture or art with cultural significance. The thesis traces the architectural inception and complex evolution of the building, its critical reception, and the proposals for redevelopment that culminated in a major refurbishment and transformation of the shopping precinct in 2006. It goes on to present an ethnographic account of the Brunswick as a social, as much as an architectural space, and an anthropological interpretation of the relationship between identity and place in terms of the specific qualities of the built environment. It shows that the material environment becomes real and vivid to people as an embodiment of the social dimensions of their lives, and that the boundaries between ‘inside’ and ‘outside’ – the private space of the home, and the layered sequence of public spaces extending through the building to the city beyond - are not objectively fixed, but subjectively perceived and negotiated in different ways. Although the Brunswick exerts considerable power as a unique architectural image, its boundaries do not define an integrated social space, nor a unified experience of the place as a living environment. Nevertheless, repeated interaction and sensory experience make it a tangible architectural framework for everyday and domestic life which evidently shapes the view from the inside looking out. The research aims to make a significant contribution to knowledge at a meeting-point between anthropology and architecture, which might help to inform future understanding of the interaction between people and the built habitat in modern urban societies.

The impervious surfaces of built landscapes create stormwater runoff that causes water quantity and quality problems downstream, upsetting natural hydrology and harming aquatic ecosystems. Green stormwater infrastructure (GSI) includes practices that reduce the amount of stormwater runoff and the pollutants it carries utilizing plants, soils, and other materials to capture, store, reuse, infiltrate, evapotranspire, and filter stormwater. GSI helps to restore developed landscapes, mimicking natural hydrologic processes and providing important water treatment functions as well as beneficial green spaces in urban areas. However, there are many challenges associated with the implementation and maintenance of GSI in our communities and cultures. This research explores the human side of implementing GSI, investigating current maintenance capacities in rural and urban settings, and exploring multifunctional benefits of GSI to provide both biophysical and cultural ecosystem services (CES). Research goals include characterizing the current state of GSI implementation and maintenance in municipalities in the State of Vermont (USA) and eliciting lessons that can inform GSI design practices and policies. Multifunctional GSI design objectives that provide and enhance CES are described, revealing opportunities to instill values and a sense of stewardship for the health wellbeing of people and ecosystems. The first chapter provides relevant topical background to set the stage for the latter two chapters. The second chapter analyzes results from a survey of municipal officials in Vermont that occurred as part of NSF-EPSCoR-funded Basin Resilience to Extreme Events project research on stormwater management. The survey included questions about GSI and maintenance practices in place and perceptions of visual appeal and ability to maintain bioretention systems shown in landscape visualizations. Results show that visual appeal and perceived maintainability of vegetated bioretention practices do not appear to be significant barriers to adoption and operation, but stormwater policy and funding are shown to be both significant barriers and solutions to implementing and maintaining GSI in Vermont municipalities. Additionally, urban and rural towns provide very different contexts for implementing and maintaining GSI in Vermont and characteristics of development patterns and maintenance capacity should be considered in policy, regulations, outreach, and education. The third chapter offers a literature review, guided by a CES framework, of design elements that can be included in GSI to create multifunctional urban green spaces. CES categories of aesthetic, recreation, education, sense of place, social capital, and stewardship benefits framed a set of design elements, principles, practices, and documented benefits to guide multifunctional design of GSI. Findings include the importance of participatory processes to elicit diverse landscape values, visible water pathways, biodiversity, spaces for creative use, accessibility, interaction with water, interpretive signage, and artful and biophilic design features to enhance feelings of preference, pleasure, relaxation, learning, connection, and inclusion. The health and wellbeing of water and people must be integrated into the design of GSI for cities to be ecologically functional and culturally meaningful to their populations.
