Personal Exposure Of Children To Formaldehyde In Perth, Western Australia, Victoria S. Lazenby
Personal Exposure Of Children To Formaldehyde In Perth, Western Australia, Victoria S. Lazenby
Theses: Doctorates and Masters
Formaldehyde is a common air pollutant that tends to be found in elevated concentrations in indoor air. Exposure to formaldehyde has the potential to impact on respiratory health, particularly amongst sensitive individuals and populations, including children. Children spend most of their time indoors at home, however, there are very little data on the contribution of formaldehyde concentrations in homes to personal exposure in children. The principal aim of this cross sectional study was to investigate whether the domestic environment is the most significant source of personal exposure of formaldehyde in children. Forty-one primary school children (aged between 8 and 12) …
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 …
An Exploration Of The Perceptions Domestic Groundwater Users Hold In Relation To Perth's Groundwater Resources, Beverley Drayton-Witty
An Exploration Of The Perceptions Domestic Groundwater Users Hold In Relation To Perth's Groundwater Resources, Beverley Drayton-Witty
Theses : Honours
Australia's water resources over the next few decades, and most likely beyond, will be under increasing pressures as populations enlarge and as the amount of water per person becomes more limited from a decline in rainfall across much of the continent. Perth is considered lucky among most Australian cities when it comes to water resources, in that we have an extensive groundwater network that is readily accessible both for both private (wells and bores) and public (scheme water) supplies. However, this resource has also seen substantial declines over the last few decades resulting from declining rainfall and increased use. Although …

Improving Community Water Conservation Behavior In Chachoengsao, Thailand, Kuakul Sathapornvajana
Theses: Doctorates and Masters
The issue of water supply throughout the world is of concern for many reasons. It is projected that by the year 2025 two-thirds of the world's population will encounter moderate to severe water shortages. As a result of unsustainable development over the past decade, Thailand has faced pollution problems as well as the depletion of many natural resources. These problems have impacted on the country's main rivers (Chaopraya River, Thachine River, and the Bangpakong River), that are crucial to a sustainable economy, society, and culture. There needs to be a concentrated effort at all levels (individual to community) to address …
An Exploration Of Thresholds Of Tolerance For Changes To Sanctuary Zones Among Repeat Tourists: A Case Of Ningaloo Marine Park, Natasha Nicholson
An Exploration Of Thresholds Of Tolerance For Changes To Sanctuary Zones Among Repeat Tourists: A Case Of Ningaloo Marine Park, Natasha Nicholson
Theses : Honours
As environmental issues become more prevalent in today' s society, natural area managers must find ways to balance the increased popularity of natural areas for recreation with environmental protection and conservational goals. One popular method to achieve this balance is through restrictions. Sanctuary zones are one type of restriction and are generally designated areas that prohibit extractive uses of natural resources, such as fishing. This study qualitatively explores the issues that affect a repeat tourist's tolerance threshold for changes to their recreational activities caused by restrictions within the Ningaloo Marine Park. This study seeks to assist natural area managers to …
Sources Of Nitrogen And Phosphorus In Stormwater Drainage From Established Residential Areas And Options For Improved Management, Surasithe Khwanboonbumpen
Sources Of Nitrogen And Phosphorus In Stormwater Drainage From Established Residential Areas And Options For Improved Management, Surasithe Khwanboonbumpen
Theses: Doctorates and Masters
From early April 2002 to June 2003, a study was conducted at Wanneroo and Bannister Creek in Perth's metropolitan area (Western Australia), aiming to quantify major sources of nitrogen (N) and phosphorus (P) entering urban residential catchments on two of the major dunal systems. The export of N and P from these catchments in stormwater discharge was measured, allowing investigation of some of the key pathways through which N and P enter the drainage network from the catchment. This information was then used to recommend catchment management approaches to reduce nutrient discharge into stormwater.
Impact Of Fire On Geophyte Abundance, Diversity And Composition In The Jarrah Forests Of South-West Western Australia, Jeffry Cargill
Impact Of Fire On Geophyte Abundance, Diversity And Composition In The Jarrah Forests Of South-West Western Australia, Jeffry Cargill
Theses : Honours
Within fire-prone environments, such as the dry sclerophyll forests of south-west Western Australia, species morphology and distributions have established and maintained long-term dynamic relationships with fire regimes. These fire regimes can alter ecosystems, creating spatial and temporal changes in species composition, structure and fuel accumulation at both local and landscape scales. The cessation of Indigenous fire regimes and the establishment and expansion of a fire vulnerable European society produced the need for fire management strategies such as prescribed burning to be implemented to ensure protection of life, property and other values. Concurrent with these human-focused objectives has been the ever-increasing …
A Study Of The Effects Of Probait On Chuditch, Dasyurus Geoffroii, Within The Julimar Conservation Park With Notes On The General Ecology, Melissa York
Theses : Honours
Broad scale fox baiting programs have been underway in Western Australia since 1996 when the Western Shield fauna recovery program commenced with the aim of recovering many fauna species that are under threat of extinction. Until recently, effective fox control for fauna recovery has been achieved with dried meat baits impregnated with the poison 1080. The Department of Conservation and Land Management (CALM) has developed more readily available and cost effective sausage meat baits, termed Probait. As bait acceptability trials in the laboratory indicated a potential risk from Pro bait ingestion by chuditch (Dasyurus geoffroii), assessment of the likely risk …
Dryland Salinity In Western Australia: A Local Government Perspective, Paul Scalzi
Dryland Salinity In Western Australia: A Local Government Perspective, Paul Scalzi
Theses : Honours
This study evaluated local government's response to the problem of dryland salinity in the Western Australian Wheatbelt, and to what extent local government has the capacity to meet its statutory obligations. Salinity is a significant environmental problem that has the potential to have a marked effect on Western Australia's economy, environment and social fabric. The problem has been the focus of much Commonwealth and State attention, but the same level of involvement is not apparent in the institution of local government. This is also reflected in the paucity of published literature in the area of local government and salinity. Local …
Investigation Into The Use Of Bait Stations For The Control Of The European Wild Rabbit (Oryctolagus Cuniculus) In The Urban Bushland Reserve Of Bold Park, Perth, Western Australia, Malin Kordes
Theses : Honours
European rabbits in Australia have a significant impact on the environment and the economy. It is therefore necessary to implement control programs. In rural areas a number of methods including warren ripping and poisoning are frequently used. In urban areas though, rabbit control is not as easily accomplished because the use of many control methods is not appropriate. For example, the poison 1080 often cannot be used due to public health concerns and warren ripping cannot be used in conservation areas. Poisoning with pindone, an anticoagulant, is therefore one of few options available to the managers of urban reserves. However, …
Natural Regeneration Of Native Vegetation On Abandoned Agricultural Land In The Fitzgerald Biosphere, Nerilee Boshammer
Natural Regeneration Of Native Vegetation On Abandoned Agricultural Land In The Fitzgerald Biosphere, Nerilee Boshammer
Theses : Honours
Much of the natural landscape in the south-west of Western Australia has been severely modified as a result of past and current agricultural activity. One of the most conspicuous changes has been the large scale clearing of native vegetation, The evidence of the negative impacts of this vegetation removal on the natural environment is now extensive, particularly in the south-west region of the State. In order to prevent further degradation of the landscape of the south-west and subsequent loss of endemic species, strategic revegetation within the agricultural landscape is required. Native vegetation corridors can be established, linking areas of remnant …

Plant Surrogacy: An Evaluation Of Its Use And Application In The Effort To Conserve Ground Dwelling Invertebrates, Kerry Leigh Ironside
Theses : Honours
A study conducted in the Ridges State Forest, Yanchep was designed to investigate the relationship between plant species richness, vegetation association and ground dwelling invertebrate species richness. Four plant communities were sampled at two scales of measurement. Two treatments were located in woodland and two in heath. Within each vegetation association, plant communities that were representative of both high and low species richness were selected. Three invertebrate orders, Araneae, Coleoptera and Araneae were sorted to morphospecies level. Ordinal richness was also investigated. Two-way ANOVAs indicated that there was no relationship between plant species richness, vegetation association· or the interaction between …
Freshwater Macroinvertebrate Response To Wetland Acidification On The Swan Coastal Plain, Jill Woodhouse
Freshwater Macroinvertebrate Response To Wetland Acidification On The Swan Coastal Plain, Jill Woodhouse
Theses : Honours
Wetlands of the Swan Coastal Plain (SCP) are acidifying because extended drying periods have exposed and oxidised sulphidic sediments creating sulphuric acid and lowering wetland pH. This appears to be the ecological equivalent of both Northern Hemisphere acid rain in lakes and streams, and acid mine drainage. This research aims to describe the characteristic acidic macroinvertebrate faunal assemblage of the SCP by identifying acidophobic and acidophilic taxa, and to examine their potential as indicators of acidification for routine biological monitoring. Four linked approaches were used in the study - analysis of a database, investigation of acidified wetland case studies, wetland …
Influences On The Uptake Of Covenant Mechanisms For Nature Conservation On Private Lands In Australia, Thomas I. Kabii
Influences On The Uptake Of Covenant Mechanisms For Nature Conservation On Private Lands In Australia, Thomas I. Kabii
Theses: Doctorates and Masters
Globally management agreements have emerged as more effective in assuring long-term nature conservation on private land, than regulatory mechanisms alone. Restrictive permanent covenants in particular, which are legally binding management agreements in perpetuity, have been adopted in most States and Territories in Australia. However, there is reluctance among landholders to take them up. Sound understanding of the factors that influence the decisions of landholders regarding the uptake of permanent covenants is important in planning and strategizing for increased covenant uptake. The aim of this thesis is to further this understanding and to support the design of a coordinated covenant mechanism …
Outcomes Of A Participatory Approach To Interpretive Planning In The Shark Bay World Heritage Area, Western Australia, Kelly J. Chapman
Outcomes Of A Participatory Approach To Interpretive Planning In The Shark Bay World Heritage Area, Western Australia, Kelly J. Chapman
Theses: Doctorates and Masters
This thesis examines a participatory approach to interpretive planning, employed in the Shark Bay World Heritage Area, Western Australia. At the project outset relations between the conservation agency responsible for administering World Heritage and the local community were strained, and complicated by a history of conflict over the World Heritage listing and subsequent management of the area. A participatory approach to interpretive planning was adopted in the hope that doing so would achieve the following: improved relations between polarised stakeholder groups, increased community support for the plan and its implementation, and improved access to the variety of knowledge pools within …
Floristics Of The Banksia Woodlands On The Wallingup Plain In Relation To Environmental Parameters, Claire Mccamish
Floristics Of The Banksia Woodlands On The Wallingup Plain In Relation To Environmental Parameters, Claire Mccamish
Theses : Honours
An understanding of the underlying environmental factors contributing to the floristic composition of Banksia woodlands should improve the effective management of Banksia woodland communities of the Swan Coastal Plain. Although a number of studies have examined the vegetation on the Banksia woodlands on detail there have been few studies aimed at identifying the specific environmental parameters influencing the floristic gradients on the Swan Coastal Plain. A comprehensive local scale study was undertaken on the northern Swan Coastal Plain to determine the environmental correlates influencing floristic communities in an area of Banks/a woodland known as the Wallingup Plain. Vegetation communities of …

Wedge Veg : Gradient Analysis Of Impacts To Coastal Heath Vegetation At Wedge, Western Australia, Steven O'Dwyer
Theses : Honours
A reliable technique to assess impacts to coastal zones is required as coastal areas across the world are under pressure from an increasing human presence. The result is a greater level of disturbance to the coast, both marine and terrestrial. This study addresses a worldwide problem but is focused to a local scale. Wedge, on the central coast of Western Australia, supports a squatter shack settlement and has done so for approximately 50 years. Over time, the number of shacks, campers, tourists, 4WD's and motorbikes has increased. In recent years this growth has been significant. Management of this area and …
Fox Control In Urban Conservation Reserves: An Analysis Of Bait Uptake And Public Perceptions In The Perth Metropolitan Area, Jennifer Jackson
Fox Control In Urban Conservation Reserves: An Analysis Of Bait Uptake And Public Perceptions In The Perth Metropolitan Area, Jennifer Jackson
Theses : Honours
As the world's population becomes increasingly urbanised, the need for people to see nature on their doorstep is becoming more appealing. The city of Perth (Western Australia) has large areas of bushland that have been reserved as conservation estate, and therefore are only minimally modified by urban development. But while many of these urban bushland reserves contribute highly to biodiversity in the form of vegetation, vertebrate surveys have indicated a low diversity of fauna. These areas have the potential to function in a more complete manner as nature reserves with significant conservation value by supporting populations of native animals which …

A Drop In The Bucket: Collective Efficacy Perceptions Affect Waste Minimising Behaviours, Leesa N. Bonniface
Theses: Doctorates and Masters
The goal of this thesis was to inform a social marketing effort designed to increase environmentally friendly behaviours in an effort to ensure a more sustainable future. This study attempted to gain a better understanding of the discrepancy that exists between pro-environmental concerns and pro-environmental actions by exploring efficacy perceptions. Efficacy beliefs were compared for three groups of individuals: 1) environmentally active/members of an environmental group; 2) environmentally active/not members of an environmental group; 3) environmentally inactive and not members of an environmental group. Six focus groups were conducted and interviewees were recruited from the Earth Carers' organisation and the …
The Fringing Halophytic Vegetation Of Lake Austin: A Study Of Mining Impacts And Vegetation Dynamics, Simone Vellekoop
The Fringing Halophytic Vegetation Of Lake Austin: A Study Of Mining Impacts And Vegetation Dynamics, Simone Vellekoop
Theses : Honours
Mining operations in arid regions of Western Australia are faced with many environmental management issues. One such issue is the disposal of mine water to the environment. Mine water is commonly discharged to nearby salt lakes under licence by the Department of Environmental Protection. Licence conditions dictate that the discharge water and the receiving environment be monitored to allow impacts on the environment to be detected. Salt lakes are associated with vegetation communities dominated by halophytic members of the Chenopodiaceae, While these plants are tolerant of salinity extremes, the germination stage of many species requires periods of lowered salinity. There …
Invasion Of Indigenous Vegetation In South-Western Australia By Leptospermum Laevigatum (Gaertn.) F. Muell. (Myrtaceae), Anya Lam
Theses : Honours
The current paradigm of biodiversity conservation requires the assessment of alien plant invaders, and their potential negative impacts on indigenous species and communities. Leptospermum laevigatum (Gaertn.) F. Muell. (Victorian tea tree/ Coast tea tree) is indigenous to eastern Australia. It has invaded ecosystems within its natural biogeographic range, within new ranges in Australia and overseas. The species is listed as a high priority weed in the Environmental Weed Strategy for Western Australia. However, the basis for its listing has been casual observation rather than focussed research. This study of L. laevigatum is unique in being the first to …
Abundance, Distribution And Population Characteristics Of Western Grey Kangaroos (Macropus Fuliginosus, Desmarest 1817) In Yellagonga Regional Park, Amy Chang
Theses : Honours
Yellagonga Regional Park is located in the northwest corridor of Perth and constitutes 1400 hectares of wetlands, parkland, open forest and open woodland. Few studies have been conducted on the native fauna in the Park's upland habitats. For this reason, a study of the abundance and distribution of western grey kangaroos (Macropus fuliginosus) was conducted. A walked survey using direct counts and individual recognition of kangaroos during winter, recorded a total of 123 kangaroos, 51 pouch young and 23 unidentified individuals in Yellagonga Regional Park, and a further 24 kangaroos and 18 pouch young at Edith Cowan University's Joondalup campus. …

The Assessment Of Satellite Remote Sensing As A Tool For Determining Sea Surface Temperatures In Nearshore Environments, Fabienne Faskel
The Assessment Of Satellite Remote Sensing As A Tool For Determining Sea Surface Temperatures In Nearshore Environments, Fabienne Faskel
Theses : Honours
The use of satellite remote sensing for environmental management applications has seen a marked increase over the past decade. Remotely sensed data are obtainable for a variety of parameters, such as mineral exploration, species migration, and for determining sea surface temperatures (SSTs). This study examined whether satellite remote sensing is a viable option for determining SSTs in coastal waters, as traditionally this application has only been applied to open-ocean, offshore waters. SSTs in the nearshore waters of Rottnest Island, Western Australia, were determined using in situ temperature loggers and remotely sensed satellite data. Initially the accuracy of the satellite sea …
Adequacy Of Terrestrial Fauna Surveys For The Preparation Of Environmental Impact Assessments In The Mining Industry Of Western Australia [Thesis], Jason L. Fraser
Adequacy Of Terrestrial Fauna Surveys For The Preparation Of Environmental Impact Assessments In The Mining Industry Of Western Australia [Thesis], Jason L. Fraser
Theses : Honours
The Environmental protection Authority has indicated that terrestrial fauna surveys as undertaken for the purpose of preparing Environmental Impact Assessment (EIA) are not providing adequate information to enable decision-makers to assess development impacts on biodiversity and ecosystems. In the absence of a protocol to assess current standards of terrestrial fauna surveys, 'best practice' was defined through discussions held with an 'expert panel', and quantified through a questionnaire. This study examined current standards of terrestrial vertebrate fauna surveys, prepared for the purpose of EIA, with 'best practice' as defined by relevant expert opinion. Strengths and weaknesses of terrestrial fauna surveys were …
Mine Dewatering In Arid, Saline Environments In Western Australia: The Response Of Biota Emerging From Rehydrated Sediments, Charelle Harkins
Mine Dewatering In Arid, Saline Environments In Western Australia: The Response Of Biota Emerging From Rehydrated Sediments, Charelle Harkins
Theses : Honours
Mine dewatering is a critical part of the mining process to prevent flooding of underground or open pits, to allow for the excavation of the available resources. Groundwater is abstracted from underground pits to the surface through extraction bores. The issue of where to discharge the excess water is a major concern. The use of natural wetlands is one option for mine water discharge. Saline lakes in arid areas are ideal receiving environments for discharge options, acting as evaporation facilities for the storage and disposal of excess mine water. Mine water discharge into ephemeral lake systems modifies the volume of …
A Framework For River Restoration Planning : Considering Conceptual And Structural Perspectives From Case Studies Of The Liao River In China And The Kalgan River In Australia, Ye Sun
Theses: Doctorates and Masters
Over the last decade, restoration ecology has been considered a new paradigm for dealing with many of the environmental problems of river systems. It is also recognized that management decisions have a greater chance of being successful if they are based on a thorough understanding of a concept or a plan. A review of current studies on river restoration and river restoration planning revealed that managers and scientists have put a substantial emphasis on ecological science and technology in restoration, while many sociopolitical and economic elements have been de-emphasized Besides this, understanding and experiences of river restoration, especially those of …
