Fuel Characteristics And Dynamics In Shrublands Of The Transitional Rainfall Zone, Western Australia, Sarah Dalgleish
Fuel Characteristics And Dynamics In Shrublands Of The Transitional Rainfall Zone, Western Australia, Sarah Dalgleish
Theses : Honours
Within the Mediterranean shrublands, fires are particularly intensive and widespread. In the Transitional Rainfall Zone in Western Australia, these large fires bum in areas with high conservation value, and present risks to human lives and infrastructure on properties in the region. The concern for the effect fires have on anthropocentric and ecological values in these shrublands makes it a priority in management to reduce the risks. Of the environmental and biotic factors that influence a fire, fuel is one of the most significant as it has the capacity to determine fire prope1iies such as the intensity, extent, bum pattern within …
Structural Characteristics Of Banksia Woodland Along An Ecohydrological Gradient, Western Australia, Rebecca Thomas
Structural Characteristics Of Banksia Woodland Along An Ecohydrological Gradient, Western Australia, Rebecca Thomas
Theses : Honours
Water availability (the defining feature of a 'hydrological habitat') has a major effect on plant growth, and the physiological and structural characteristics of plants often reflect the availability of this resource. In relation to development of vegetation structural characteristics as a consequence of a given hydrological habitat, it is important to understand whether self-organisation of plant cover (productivity, structure and function) interacts with water availability and if adjustment to water limitation exists ('ecohydrological optimization' or establishment of a 'hydrological equilibrium'). This study tested, through three hypotheses, whether structural and functional attributes of Banksia woodland vary with water availability, i.e. whether …
Historical Geography Of Yellagonga Regional Park, Western Australia, Susan Ujma
Historical Geography Of Yellagonga Regional Park, Western Australia, Susan Ujma
Theses : Honours
The principle aim of this study was to reconstruct the land use history of the Yellagonga Regional Park wetland landscape. Located approximately twenty kilometres north of Perth, covering about 1400 hectares, the Park lies within the North-West Corridor of the metropolitan area. This research, assisted by archival sources, demonstrates that prior to early European settlement the Yellagonga wetlands were quintessential summer hunting and gathering sites for the Nyoongar Aboriginal people. The wetlands were utilised for water, food gathering, hunting, corroborees and rituals that governed their tribal lives. Early European settlers, market gardeners, and later subdivision for urban development, have adversely …
