The expansion of suburbia into undeveloped lands has had a major effect on our urban environments. These effects have resulted in both businesses and residents leaving cities for the greener pastures of suburbia. As a result many neighborhoods in cities such as Detroit have been left vacant and rundown. These left over sites offer a chance to bring new life to the communities in which they are located. New affordable communities can be created within the urban core, thus providing a new start for local residents and a reason for suburbanites to relocate back to the city.This project will be focusing on a redevelopment plan for the Historic Ford Model-T factory in Highland Park, Michigan. This small community lies within the borders of the city of Detroit and suffers from many of the previously described problems. Inadequate housing is a major issue for the city's residents along with the negative image that these vacant and run-down buildings portray. Recent developments show that there is an interest in reinvestment within the city through two recently constructed shopping plazas, and a new industrial complex that are within one city block of the site. Providing appealing housing options incorporated with places of business, can bring life back to a city that has lost so much as seen in other communities. The advent of the affordable automobile and highway system has helped in the demise of this community. This site is an important link to the areas past and present heritage as the motor capital of the world. Henry Ford was very involved in the creation of communities by building entire towns in order to provide housing for his workers, which is why this site is perfect to redevelop with housing. The main goal for this project is to create a better place to live for the current and future residents and a place that symbolizes the identity of its rich manufacturing past. The final product will be a conceptual master plan that will fit within an urban environment and meet the needs of the community. The methodology that I will use will consist of literature review and case studies of similar projects. It is my intention that this information will aid me in creating a conceptual master plan based on my two primary goals: to create a safe and unique place for the residents to call home and create a catalyst for more development. / Department of Landscape Architecture

[Truncated abstract] Aspects of the biology of the commercial sea cucumber Holothuria whitmaei were investigated at Coral Bay, Ningaloo Reef, Western Australia. The study was partitioned into several components: i) spatial distribution, ii) temporal changes in behaviour and iii) reproduction biology. The spatial distribution of H. whitmaei at Coral Bay was typical of that reported in the literature. H. whitmaei had distinct preferences for outer reef habitats, including the outer reef flat and reef slope. However, the distribution of H. whitmaei within these habitats was heterogeneous, or, aggregated within certain micro-habitat zones - predominantly at the leading edge of the reef flat, perpendicular to the prevailing current. Two potential biological advantages of this distribution were hypothesised: i), that species aggregation enhances prospects for gamete fertilisation, a process which may be impeded under typical densities, and ii), large deposits of detrital matter, an important food source for holothurians, may accumulate within these zones. ... A striking feature of the reproduction biology of this species was the potential for specimens to mature asynchronously. It was hypothesised that this phenomenon may be a reflection of isolated individuals located too far from conspecifics to receive pheromone signals; cues which are known to entrain synchronous gonad development in some holothurians. Hence, it was proposed that aggregations of H. whitmaei may be important to the maintenance of population recruitment, given that animals at the periphery of species concentrations may have relatively little chance of achieving fertilisation. ... Given that H. whitmaei were observed to maintain highly specific patterns of distribution, this may have significant ramifications for trophic level cascades in the outer reef zone, particularly where this species is present in higher densities (i.e. >100 ind. ha-1). The findings of this study, apart from highlighting the spatial and temporal biological attributes which may facilitate feeding and reproductive success, also emphasised the importance of biological knowledge to the management of sea cucumber fisheries. The study highlighted the need for further research to ascertain both the importance of species aggregations to population recruitment, and of the actual densities required to achieve high rates of gamete fertilisation. Such knowledge may help ultimately to identify suitable habitats for inclusion in marine protected areas.

M.Sc. / OBJECTIVES Tourism in the Kruger National Park is closely linked to nature conservation. Tourism being the revenue earner and conservation the resource provider; this results in a mutually beneficial symbiosis. This finely tuned interdependence between tourism and conservation should be properly managed to ensure that tourism does not become a self-destructive process, destroying the very resources on which it is based. Mounting pressure from central government is forcing the National Parks Board to become financially independent of State grants. Tourism provides the most viable solution towards achieving financial independence. All the national parks in South Africa will therefore have to make a concerted effort to accommodate and attract more tourists. The Kruger National Park, being the largest national park (1 948 528 hectares), will have to make a major contribution towards financial independence. In order to achieve this goal, tourism in this Park will have to be planned and managed more effectively. It is within this context that this study was initiated. In order to facilitate future tourism planning and management, the study will investigate the number of tourists visiting the Kruger National Park as well as the occupation of accommodation by tourists. These results will in turn be used to investigate the tourist carrying capacity of the Park and to make suggestions regarding the Park's tourism management policies. RESEARCH METHOD As a result of the primarily descriptive nature of the investigation relating to the number of tourists visiting the Park as well as the occupation of accommodation by tourists, the research will include diagrammatic and cartographic representations of the data. In order to explain the temporal and spatial variations of the tourists in the Kruger National Park, a correlation and regression analysis was used in conjunction with non-tourist variables (which include both socio-economic and physical variables). The results obtained in the above investigation were used to study the physical and perceptual tourist carrying capacity. Physical tourist carrying capacity was researched by indicating the percentage occupation of available accommodation and available day visitor quota. As a result of the its subjective nature, the balance between the costs and benefits associated with gaining a holiday experience was used in conjunction with the number of visitors to the Park in order to determine the perceptual tourist carrying capacity. RESULTS The number of visitors to the Park as well as the occupation of accommodation by tourists both indicated that large temporal and spatial variations exist. The temporal variations in tourist data were best explained by school holidays. An obvious relationship exists between school holidays and the number of visitors to the Park. The spatial variation was best explained by distance from the PWV and rainfall. The distance from the PWV (now Gauteng Province) indicates the strong influence of this region as a source area for tourists to the Park. Rainfall in the Park influences the type of vegetation, which in turn influences the distribution and population densities of animals which are sought after by tourists. With regard to the tourist carrying capacity, the results showed that the physical tourist carrying capacity is utilised below the optimum levels. More tourists can therefore be accommodated, particularly during non-school holiday periods. With reference to the perceptual tourist carrying capacity, it was found that it has been reached. The most important reason for this is the higher tariffs that are being charged.

The status, distribution and ecology of klipspringer were studied in the Kruger National Park. For the status and distribution, the Kruger National Park south of the Olifants River was used as the study area. Data on the status and distribution were gathered from all the ranger sections in the study area with the use of a non-sampling method, namely a systematic search. The results showed that the klipspringer population in the Kruger National Park is secure with a patchy distribution consisting of 773 individuals in the study area and a sex ratio of one male per 1.1 female. The ecology of the klipspringer was studied in a specific study area on the Nwatindlopfu spruit between Skukuza and Tshokwane where five klipspringer individuals were radio collared. The aspects covered in the study on the ecology of klipspringer, were the activities associated with environmental and vegetation related variables as well as scent-marking. It was found that vegetation is the determining factor in the habitat selection of klipspringer in the Kruger National Park, in that it provides both shelter and food. The ideal klipspringer habitat can be described as an area that has limited access to other ungulates that can attract predators. The vegetation should consist of palatable plant species that could be utilized by klipspringer, and must also provide sufficient shelter against possible danger. Klipspringer scent marks were surveyed in a specific klipspringer range in the Kruger National Park with the use of a strip transect method. Both the male and the female klipspringer scent-mark their ranges. A pair of pre-orbital glands below the eyes produces the scent. The secretion produced is a sticky milky substance that is deposited on a suitable twig. The results showed that klipspringer in the Kruger National Park scent-¬mark more frequently on the boundaries of their ranges and also more on those sides where there is another resident klipspringer group. / Dissertation (MSc (Wildlife Management))--University of Pretoria, 2005. / Animal and Wildlife Sciences / unrestricted

An investigation of the relationship between the physical, pedological and anthropogenic influences on landslide occurrence on the midslopes within and outside Mt Elgon National Park was carried out. One of the landslides occurred in a protected pristine forest environment within the Park while the other two were located at sites deforested for cultivation within and outside the National Park. Field based surveys, GIS techniques and laboratory tests were used to collect and analyze the data. A household survey was undertaken to establish the main community livelihood strategies, the drivers of land use change and implications for land degradation on the mid slopes of Mt Elgon. Aerial photographs taken in 1960 and orthophoto maps formed the benchmark for the analysis of the respective land use changes between 1995 and 2006, using 30m Landsat TM and 20m SPOT MS images in IDRISI Andes GIS environment. Landslide sites were mapped using a Magellan Professional MobileMapperTMCX and terrain parameters were derived using a 15M Digital Elevation Model. A hybrid supervised/unsupervised classification approach was employed to generate land cover maps from which the areal extent of three land cover classes (agricultural fields, woodlands and forests) was calculated. Particle size distribution and atterberg limits were used to test the hypothesis that soils at the landslide sites are inherently ‘problem soils’ where slope failure can occur even without human intervention. Shear strength parameters (internal of friction and cohesion) were used calculate the slope factor of safety to ascertain slope stability at pristine and disturbed landslide sites. Results from the socio-economic survey revealed that smallholder subsistence agriculture and encroachment on the National Park resources are the main sources of livelihoods for the communities surrounding the Park. The communities also have a strong socio-cultural attachment to the National Park, as it is the source of items used during traditional rituals like circumcision. Encroachment is driven by the high population pressure and the prevalent political climate. Farmers mainly use slash and burn technique to prepare land for cultivation and those close to the National Park are reluctant to adopt appropriate farming and soil conservation practices due to the uncertainties surrounding their future on such plots. Slash and burn iii techniques were observed to accelerate various forms of erosion including rills, gullies and sheet. Soil and water conservation techniques were mainly practiced on privately owned farms. The period 1960 and 1995 was characterized by minimal land use changes and no encroachment into the designated Mount Elgon National Park. Conversely, the period 1995 – 2006 marked a significant loss of woodlands and forest cover particularly on steep concave slopes (36º – 58º) within the National Park. The land use change trends were attributed to the prevalent land politics and exponential population growth in the region. The encroachment onto the critical slopes was noted to have induced a series of shallow and deep landslides in the area. Deforestation on Mt Elgon was reported to have both onsite and offsite climate variability and implications in the form of drought, heat waves, flash floods, economic dislocation, crop failure and associated malnutrition in surrounding low lying areas. The soils on pristine and disturbed slopes contain high amount of clay (>10 percent), are fine textured (>50 percent of the material passing the 0.075mm sieve) and highly plastic. These soil attributes imply low permeability, excessive water retention and high susceptibility to expansion and sliding. The vertic nature of soils at Nametsi was confirmed by the extremely high plasticity indices (averaging 33percent), while, high liquid limits at Buwabwala (53 percent) and Kitati (59 percent) qualified the soils as vertisols which are associated with landslides. The results point to the fact that soils at landslide sites are inherently ‘problem soils’ where slope failure can occur even without human intervention. Therefore, the hypothesis that soils at three landslide sites are inherently ‘problem soils’ where slope failure can occur even without human intervention is accepted. Notwithstanding the fact that the study was focussed on mid-altitude slopes of Mt Elgon, the results are in tandem with investigations carried out earlier on the lower densely populated slopes, thus confirming the widespread nature of problem soils on Mt Elgon. There is an urgent need to control human population growth and restore forest cover on the heavily deforested steep slopes particularly within the National Park, and restrain communities from encroaching on the pristine slopes of Mt Elgon. This will be achieved if the politicians, Park Authorities and local communities jointly participate in the design and implementation of CFMs. Future research could focus on climate change implications of deforestation of Mt Elgon environments and quantification of carbon loss related to deforestation and soil degradation in the mountain environments.

Holocene patterns of sediment yield reconstructed from sediments in four lakes are used to assess the geomorphic sensitivity of four alpine-subalpine basins in Cathedral Provincial Park, British Columbia. A three stage process was used to assess basin sensitivity. Stage one involved appraisal of the potential generalisability over the landscape of the results to be derived from the lake basins. The four lakes, Quiniscoe , Glacier, Pyramid and Lake of the Woods lie at or just below treeline. Glacier, Pyramid and Quiniscoe lakes lie in cirque basins. Slope frequency analyses show that whilst slopes in these basins are representative of those in the cirques of Cathedral park they differ significantly from the wider landscape. Stage two of the process involved identification of Holocene variability in the sediment yield record. Cores from each of the lakes were correlated using magnetic susceptibility measurements and lithostratigraphy to define chronostratigraphic units. The mass of allochthonous mineral sediment deposited in each of these units was estimated using measured sediment density, carbonate content, loss on ignition, and biogenic silica. Sediment yield to the lake for each unit was calculated based on dating of zone boundaries, estimates of trap efficiency, and the mineral mass estimate. In order to identify significant variations in the record, a new method was developed for estimating error associated sediment yield estimates derived from lake sediments. Sediment yield estimates were compared with the published Holocene climate record to make an initial assessment of sensitivity. Stage three involved discriminating between true sensitivity to climate change in the record and coincidental correlation. The approach was to identify process linkages between the observed changes in sediment yield and the climate change record. Two methods of inferring process were used. Firstly process change was inferred directly from the sedimentology of the lake sediments. Secondly magnetic and mineralogical characterisations of lake and catchment sediments were used to identify changing sediment sources. The results show considerable variability in the patterns of Holocene sediment yield amongst the study basins. In particular, Glacier and Quiniscoe Lakes show a marked increase in sediment yield under cooler conditions ca. 3390 BP, which is not apparent at Pyramid and Lake of the Woods. The increase is driven by increased surface erosion in the two higher basins under cooler conditions, and with retreating treeline. The results suggest that the sensitivity of alpine and subalpine basins is both temporally and spatially contingent. The links between climate change, process change and variation in sediment yield are not simple, rather they is mediated by a series of 'resistances'. The variability in sediment yield was compared with the variable nature of the catchments and four important controls were identified: Sediment production, vegetation, relief, and the extent of fluvial development in the catchment. Maximum sensitivity was observed in steep ecotonal sites with a well developed fluvial system. / Arts, Faculty of / Geography, Department of / Graduate
