Orientador: Marta Enokibara / Banca: Norma Regina Truppel Constantino / Banca: Maria Lucia Bressan Pinheiro / Resumo: O botânico brasileiro Frederico Carlos Hoehne (1882-1959) iniciou sua carreira como jardineiro-chefe do Museu Nacional do Rio de Janeiro em 1907. No ano de 1917, ao ser convidado para fundar o Horto Oswaldo Cruz no Instituto Butantã, se muda para São Paulo, onde solidifica sua carreira fundando e dirigindo hortos e instituições de pesquisa até o ano de 1952, quando se aposenta. Hoehne é reconhecido como um grande defensor da natureza e também por sua paixão por orquídeas. Contudo, este trabalho tem como objetivo investigar um aspecto ainda pouco explorado na vasta produção do autor, referente ao seu estudo para a indicação de espécies nativas para a arborização urbana. Publicado em 1944, o livro "Arborização Urbana" foi um dos primeiros a tratar sobre este tema, se aproximando dos manuais de arborização atuais. A investigação sobre quais eram essas espécies, sua relação com as espécies do manual de arborização mais recente da cidade de São Paulo (2015) e a origem das referências que subsidiaram Hoehne a indicar tais espécies foram o fio condutor da pesquisa apoiada nos Relatórios escritos pelo autor nas instituições em que trabalhou. O objetivo específico é verificar a atualidade e a contribuição do botânico para a preservação das árvores nativas e sua difusão no meio urbano. / Abstract: The brazilian botanist Frederico Carlos Hoehne (1882-1959) began his career as head gardener of the National Museum of Rio de Janeiro in 1907. In 1917, when invited to found Horto Oswaldo Cruz in the Butantã Institute, he moves to São Paulo, where he solidifies his career by founding and directing gardens and research institutions until 1952, when he retires. Hoehne is recognized as a great advocate of nature and also for his passion for orchids. However, this work aims to investigate an aspect not much explored in the vast production of the author, about his study for the indication of native species for urban afforestation. Published in 1944, the book "Arborização Urbana" was one of the first to address this issue, approaching the current urban afforestation manuals. The research on these species, their relation to the species of the most recent urban afforestation manual of the city of São Paulo (2015) and the origin of the references that subsidized Hoehne to indicate such species was the guiding line of the research, which relied on Reports written by the author in the institutions that worked. The specific objective is to verify the actuality and the contribution of the botanist for the preservation of the native trees and their diffusion in the urban environment. / Mestre

In Vancouver, British Columbia, Canada, issues once thought isolated to large metropolitan areas such as Los Angeles, Tokyo, and Mexico City—increased storm water runoff, the urban heat island effect, deterioration of air and water quality, and loss of habitat and biodiversity—now threaten a region once described as "lotus-land" (Wynn and Oke, 1992, xi). European research supports the ability of green roofs to mitigate many of these ill effects of urbanization. The investigation undertaken by this thesis explores the role green roofs might play in the Greater Vancouver's transition to sustainable design and development. The thesis limits the scope of its investigation to inaccessible, extensive systems, alternately known as eco-roofs, which are relatively lightweight and low-maintenance. The paper reviews the historical and contemporary development of eco-roofs, including past and present motivations for their use and the evolution of construction methods. It then summarizes the potential impacts—aesthetic improvements, increased biodiversity, protection of the roof membrane, meso and microclimate mitigation, improved building insulation, and stormwater management—currently attributed to green roof implementation. The remainder of the thesis evaluates which of these potential impacts apply to Vancouver, in light of the city's physical contextual setting, and the ambient influences of the Greater Regional District The reported benefits of green roofs are numerous, and incremental contributions to improving environmental conditions should not be discounted or trivialized, however, in Vancouver and its region, eco-roofs' greatest impact, and consequently financial feasibility, resides in the mitigation of stormwater volumes. Eco-roofs' detain rainfall and slow runoff from the roof during and immediately following a storm event. This reduces peak flows, and corresponding CSO and flooding problems, and encourages a more natural hydrology by increasing the chances for stormwater infiltration. Storm runoff, and issues related to it, constitutes a persistent and growing problem in the GVRD. The ability of an eco-roofs even thin profile to mitigate this pressing issue could result in widespread, and even unforeseen, positive ramifications.

This creative project presents a review of the literature of urban forestry issues and a case study which demonstrates application of this literature review to the urban forest of the City of Anderson.The planning process of the case study includes a street tree inventory, and developsexisting Land Use and Transportation land classification system related to the Plans for the City of Anderson. The classification system ties the urban forest guidelines to prototypical situations which are documented through photographs and drawings. The methodology of the classification system can provide a model for development of methodology appropriate for evaluation of other communities. The recommended plant lists are included to be used in conjunction with the guidelines.In order to provide the Madison County Council of Governments and citizens of Anderson with recommendations based on results of the study, Section E of Chapter III, Design and Urban Forestry Guidelines, is organized so that it can be removed from the text and reprinted as a separate document for general distribution. / Department of Landscape Architecture

The goals of this project were to: (1) combine the ARC/INFO Geographic Information System (GIS) software with the TIGER data files and tree inventory data files, (2) demonstrate GIS as a tool in street tree inventory management, (3) answer a management related question, specifically the identification of dead and hazardous trees within the city, with the use of the GIS tool, and (4) prepare an article based on the project for submission to the Journal of Arboriculture.Dead and hazardous trees located along a city street are a major accident liability to a city. It is vital, for both safety and aesthetic purposes, that a community know the location of dead and hazardous trees. As a management tool the GIS can utilize the inventory data to aid the urban forester in interpreting the urban forest by identifying these tree locations. Through the use of point-in-polygon analysis and choropleth maps, these specific management concerns can be highlighted throughout the city.The power to visually demonstrate certain parts of town with higher concentrations of work needed is one way that GIS can provide the management tools necessary for better care of our urban forests. / Department of Landscape Architecture

The effects of high sodium chloride (NaCl) levels on Na and nutrient retention of three soil substrates and on littleleaf linden growth in different soil substrates were studied in the laboratory and the greenhouse, within the framework of a substrate selection program for trees planted in downtown Montreal. In addition, the effects of the structural soil (SS) compaction were studied in the first greenhouse experiment. The first greenhouse experiment was established in a factorial arrangement of four soils x four salt levels in a completely randomized design with five replicates. The four soil types were (1) L with a bulk density (BD) of 1.53 g/cm3, (2) LP with a BD of 1.26 g/cm3, (3) SS with a BD of 1.8 g/cm 3 (SS1.8), and (4) SS with a BD of 2.0 g/cm3 (SS2.0). The second greenhouse experiment had a split plot design. Two fertilization levels (with fertilizer and without fertilizer) were randomly arranged as the main plots on ten benches. Within each main plot, the combinations of three NaCl levels (0, 0.5 and 1.0 g NaCl/kg soil) and three soil substrates (L with a BD of 1.40 g/cm3, LP with a BD of 1.13 g/cm 3 and SS2.0) were randomized in the sub-plots. Results from the laboratory leaching experiment indicated that SS had the fastest Na leaching rate and highest Na loss, while LP retained more Na than SS or L. (Abstract shortened by UMI.)
