The efficacy of using a natural soil additive for the establishment, survival and diversity of native prairie and spontaneously colonizing plant communities on unirrigated green roofs in a humid subtropical climateLackey, Gordon Mims, Jr. 09 May 2015 (has links)
<p> Green roofs are an emerging technology promoted primarily for stormwater management but little has been published about their potential for biodiversity performance. This is the first study to explore the potential for creating prairie-like, non-succulent, native plant communities on unirrigated extensive green roofs in the southeastern United States. Ten experimental green roof platforms were used to: 1) identify native species and methods of establishment appropriate for green roof applications in the southeastern United States; 2) examine the effects of introducing natural soil into a commercially available green roof soil media mixture on the survival and establishment of native prairie species; and 3) examine the composition of early successional green roof plant communities. Eleven planted species were successfully established and 46 colonizing species were identified. It was found that the addition of native prairie soil did not significantly affect survival, overall cover, or biodiversity in terms of species richness and evenness.</p>

Sympathetic Landscapes: an aesthetics for the Leslie Street SpitChan, Alexander January 2013 (has links)
The Leslie Street Spit is a five kilometre rubble breakwater on the eastern waterfront of Toronto. Built during the mid-twentieth-century as an infrastructural add-on to the existing Port Lands Industrial District, the artificial peninsula was a lakefilling project made to realize the city???s ambitious desire for economic prosperity and world-class prestige by expanding its existing harbour facilities. With the decline of Toronto???s shipping industry, the Leslie Spit remained an active dump site for urban clean fill until it was unexpectedly colonized by flora and fauna during the 1970s. The site is now recognized as an important local and international environmental resource.
Visitors to the Leslie Spit experience a diverse landscape of ecosystems and industrial rubble helded by the city as a symbol of environmental revival within a former industrial region undergoing another phase of urbanization. While the local aesthetic experience of the headland is pleasurable and aligns with the reinvention of Toronto as am environmentally conscious and sustainable city, human visitors remain psychologically and physically removed from the inhabiting non-human life. Occasionally, the desire to conserve and preserve the natural world requires a separation between humans and non-humans.
This relationship is carried out in varying degrees on the Leslie Spit. This thesis documents events at the headland where the human/non-human divide is rigidly enforced or left ambiguous. The purpose of the thesis is not to treat the headland as an eccentric spectacle, but to investigate the unexpected coexistence between humans and non-humans.

Finding nature in the city| A case study of ecological restoration in an urban parkKocs, Elizabeth A. 03 January 2014 (has links)
<p> This dissertation presents a case study of ecological restoration in an urban park, using a mixed-methods methodology that included a survey instrument, open-ended interviews, behavioral and trace observations, and modified grounded theory methodology for data analysis. The purpose of the study was to identify values that users of four ecologically restored areas of Chicago's Lincoln Park associated with their use of the park areas and to determine the extent to which they experienced contact with nature while visiting the areas. The study was conducted within the framework of a post-occupancy evaluation (POE) of the restoration projects, the Lincoln Park Evaluation Study in the College of Architecture, Design and the Arts, University of Illinois at Chicago, which was commissioned by the U.S. Forest Service. The author, the principal investigator for the POE, developed a set of ten values or benefits associated with park use that were included in the survey instrument and informed the onsite, open-ended interviews with park users--beauty, solitude, tranquility, recreation, health, contact with nature, habitat preservation/restoration, community identity, public life, tourism, and other (to allow respondents to add their own values to the list). The results of the study indicate that users valued contact with nature and habitat restoration most, followed closely by tranquility, solitude, and beauty, with health and recreation next and public life and community identity trailing all others. No new values were added. Data analysis suggested that respondents fell roughly into two camps, those who valued contact with nature most and those who valued habitat restoration most. Respondents who selected tranquility, solitude, or beauty as important values viewed them as secondary to contact with nature or habitat restoration because the former would be unavailable without the latter. The study's results complicates the dichotomy between natural and built environments, as respondents praised the restored areas--arguably built environments--as refuges from the city. A theme that emerged from qualitative data analysis suggests that ecological restoration of urban parks might be related to nature-identities, emotional bonds with types of natural areas, calling for future research to determine the relationship between urban nature and urban residents' nature-identities.</p>
