The object of this thesis is to provide, through a thorough analysis of human perception and interaction with aesthetics and landscape quality, a comprehensive basis on which to develop a credible methodology for the large scale assessment of perceived landscape quality. The analysis of human perception and interaction with aesthetics and landscape quality is gained by inquiring in depth into a range of theoretical constructs from key disciplines, cultural aspects, and empirical studies covering : 1. the contribution of philosophers to aesthetics 2. the psychology of perception and colour 3. the contribution of Gestalt psychology to aesthetics 4. the psychoanalytical construct of human responses to aesthetics 5. the influence of culture on landscape preferences, tracing the changing perceptions of mountains, the portrayal of landscapes in art, and the design of parks and gardens 6. a review of over 200 surveys of landscape quality in the late 20th century, including typologies and theories of landscape quality Based on the analysis of these and the knowledge gained, an empirical study is formulated and conducted, comprising a study of landscape quality of South Australia, an area of nearly 1 million km - 1. This involves, firstly, the acquisition of data covering the delineation of landscape character regions for the State, photography of these landscapes, derivation of a set of representative slides, and rating of these by groups of participants. Secondly, these preference ratings are comprehensively analysed on the basis of the attributes of the scenes covering land form, land cover, land use, water bodies, naturalism, diversity and colour. Thirdly, the results are applied as follows: 1. a map of landscape quality of South Australia is derived 2. the results are used to predict the effect that changes in land use ( e.g. clearance of trees ) will have on landscape quality 3. the theoretical constructs of landscape quality are evaluated on the basis of the preference ratings 4. a protocol is detailed to guide the undertaking of large - scale landscape quality assessment. The thesis thus fulfils the objective of conducting a thorough analysis of human perception and interaction with, aesthetics and landscape quality, to provide a basis for developing a credible methodology for the large - scale assessment of perceived landscape quality.

Bibliography: leaves 185-200. The herbicides norflurazon, oxadiazon, oxyfluoren, trifluralin and simazine used in South Australian viticulture were assessed for mobility and degradation through a combination of laboratory and field experiments. Sorption, leaching and dissipation rates were measured, as was presence in shallow groundwater. The fate of herbicides from vine to wine was also investigated, tests being conducted on herbicide residue in both white and red grapes and presence in wine. A proposal for good environmental management of herbicide use in vineyards to minimise the effects of herbicides was also developed.

Thesis (M.Law. (Development and Management)) --University of Limpopo, 2009
This research investigates the relationship between the right to development and the right to the environment. An overview of the legislative framework aimed at facilitating development and environmental protection is discussed. The right to development is aimed at improving the quality of life and living conditions of ordinary people. On the other hand, the right to the environment has as its purpose the conservation and prudent utilisation of natural resources. Theoretically, the two rights are at loggerheads. However, at the centre of these rights is the concept of sustainable development. Sustainable development harmonises the implementation of developmental activities and environmental protection, by compelling government authorities and developers to consider environmental issues when implementing development projects. Public participation is vital in environmental law as it ensures that the public is well informed about development projects that may have adverse effects on the environment. Public participation in development projects is part of the Environmental Impact Assessment process (EIA). A case study of a local township was conducted to illustrate the importance of public participation and the acceptance of the right to development and the right to the environment as justiciable human rights in South Africa. The study revealed that local government officials lack the necessary knowledge and skills to implement development and environmental laws at local community level. This results in non- compliance with the existing environmental laws by developers. It is concluded that right to development and the right to the environment co-exist and are mutual reinforcing. Therefore, failure to ensure proper implementation of the two rights may result in short- lived and unsustainable development, projects and programs. It is concluded further that non-compliance with the EIA procedure defeats the concept of public participation as embodied in environmental law and international environmental instruments. It is recommended that the government should equip its officials and citizens with skills and knowledge on how environmental laws operate and should be implemented.

The Constitution of the Republic of South Africa ‘despite being one of the world’s most liberal constitutions, South Africans still have no transparent and participatory mechanisms for deciding democratically on the uptake of new technologies or development projects, even those which impact on millions of lives and livelihoods. There are limited opportunities for intervention in very circumscribed public participation processes, which are often derisory in the sharing of any sovereignty with citizens in the name of producing better public policy. When citizens are left out of debates confined to government and the business community, the only means of influencing policy is to petition, protest, or litigate, usually after the horse has bolted.’ Public participation is a very delicate issue in South Africa due to the history of the exclusion of certain people from the process of governance. When governments and business sectors make decisions about land development and natural resources, they certainly impact on the health, livelihoods and quality of life of local communities.

Bibliography: leaves 99-105. Examines the ways in which local governments in the Adelaide region have used the Local Agenda 21 program, with particular focus on public participation and the development of indicators. Argues that sustainability requires the support and involvement of the widest possible community, a necessity that will not be realised until public participation, particularly involving those groups with a reduced 'social voice' (such as women, youth and minority cultural/ethnic groups), becomes an integral part of the local government's modernisation agenda. Concludes with a summary of the main issues and a set of recommendations for future research and action.

Pittosporum undulatum Vent. (Sweet Pittosporum) is a densely foliaged tall shrub or small tree, native to the wet forests of south east Australia, This species now functions as a serious environmental weed in a range of habitats in Australia and on other continents and islands throughout the temperate, sub-tropical and tropical zones. This study investigated some of the ecological causes and consequences of P. undulatum invasion across a range of habitat types in south east Australia. Key aspects of P. undulatum biology and ecology investigated in the current study include; patterns of morphological variation across the range of habitats occupied (as a measure of the species’ plasticity), dispersal ecology and seed germinability, population structure and spatial pattern, community relationships and the ecological impacts of invasion. Phenotypic plasticity is considerable in P. undulatum. No clear patterns of geographic variation emerged from a study of leaf morphological attributes across the current range of this species on mainland south east Australia. The pattern of morphological variation is particularly complex in Victoria, where the invasion of this species is most advanced. The species’ adaptability to a range of environments and environmental conditions will likely promote further range expansion. The abundant winter fruit crop produced by functionally female P. undulatum plants attracts a suite of generalist opportunistic frugivores, which feed on P. undulatum fruits and seeds at various stages of fruit dehiscence, thereby enhancing dispersal opportunities for this species. P. undulatum seed collected from natural and invasive populations, at two stages of fruit maturity and from the scats and pellets of dispersal agents, displayed high germinability. European Blackbirds and Pied Currawongs are implicated as the main avian dispersal agents of P undulatum in south east Australia. The broader ecological implications of developing relationships between invasive fleshy-fruited bird-dispersed plant species and adaptive frugivores are likely to be considerable. The distribution of P. undulatutn seedlings was significantly negatively correlated with adult conspecifics and significantly positively correlated with trees and shrubs of other genera. This pattern reflects the importance of both firugivorous dispersal agents and the species’ germination and establishment requirements, in shaping the contagious distribution pattern typical of this species. These analyses suggest that recruitment opportunities for conspecific seedlings are limited beneath the canopy of adult conspecifics. Densities of P. undulatum were on average, 2.7 times higher in invaded populations, compared to the natural populations sampled. A male-bias was evident in all populations and no relationships between reproductive activity and the density of seedlings and juveniles were evident. Invading populations of P. undulatum impose substantial changes on ecosystem-level properties and functions. Mean species richness and cover-abundance declined notably once P. undulatum cover-abundance exceeded 20% at the invaded sites and 60% at the natural sites sampled. The natural communities sampled displayed comparatively greater resilience to the competitive effects of P. undulatum, but community attributes were affected at high densities and cover-abundance of this species. The cover-abundance of herbs and grasses declined most substantially with increasing P. undulatum at invaded sites, whereas, at the natural sites sampled, the species’ structural analogues appeared to be most affected by increasing P. undulatum cover-abundance. This study has demonstrated that the ecological consequences of P. undulatum population expansion are substantial and contribute to changes in the composition and successional trajectory of affected communities. These processes ultimately lead to the loss and simplification of biodiversity values and the homogenisation of affected habitats. P. undulatum has the potential to emerge as one of south east Australia's most serious environmental weed species.

Aims to identify current risk factors for asthma and to determine which of these factors, at the population level, is associated with asthma prevalence in children in South Australia. In addition, modelling techniques are used to determine which factors are significant predictors of asthma prevalence in 4 to 5 year old children in S.A. Study results show that at the population level, 9 risk factors are significantly associated with lifetime prevalence and 24 factors with period prevalence. Study findings are generally consistent with existing literature.

Thesis (M.A.)--Stellenbosch University, 2001.
ENGLISH ABSTRACT: There is a general consensus that EIA is limited in its scope. The main concern in this regard is that EIA generally fails to handle cumulative impacts effectively, due to its focus on individual projects. Cumulative effects are changes to the environment that are caused by an action in combination with other past, present and future human actions. The evaluation of cumulative effects generally focuses on potential pervasive, regional environmental problems. Due to its strong focus on sustainable development, Strategic Environmental Assessment (SEA), by definition, should address cumulative effects. EIAs in South Africa traditionally only considered the "footprint" or area covered by each project component. However, in recent years the cumulative nature of environmental impacts of human actions has increasingly become a visible concern to the South African public, which has led to the need to infuse cumulative effects concepts into environmental assessments. In theory, a SEA is aimed at improving the way in which cumulative effects are dealt with in environmental assessments. This raises the question of whether past and present South African SEA approaches have effectively addressed the issue of cumulative effects. This thesis provides a critical reappraisal of recent experience in SEA with particular reference to its application in South Africa. It is in this context, of the opportunities and constraints of current SEA application, that this study attempts to determine how best to infuse cumulative effects methodology and philosophy into the emerging South African SEA process. This study evaluates three SEA case studies undertaken in South African, in order to assess how effectively cumulative effects are addressed within the current South African SEA process. The analysis focuses on both innovative approaches used in each study, as well as the limitations and deficiencies of each approach. A generic framework was developed in order to provide broad guidelines for practitioners and reviewers. These guidelines focus on how best to infuse cumulative effects philosophy and methodology into the current SEA process. It is envisaged that this methodology will enhance the current SEA process, in order to ensure that environmental issues are placed on the same level as economic and social considerations in future decision making, to achieve sustainable development.

This thesis uses an action research methodology to develop a framework for improving independent scholarly reporting about interventions addressing social or environmental conflict. As there are often contradictory interpretations about the causes and strategic responses to conflict, the problem confronting scholar-reporters is how to address perceptions of bias and reflexively specify the purpose of reporting. It is proposed that scholar-reporters require grounding in conventional realist-based social theory but equally ability to incorporate theoretical ideas generated in more idealist-based peace research and applied conflict resolution studies. To do this scholar-reporters can take a comparative approach systematically developed through an integrated framework as described in this thesis. Conceptual and theoretical considerations that support both conventional and more radical constructions are comparatively analysed and then tested in relation to a case study. In 2000 Aboriginal people throughout South Australia deliberated whether their native title claims could be better accorded recognition through conservative court processes or a negotiation process to allay deep-seated conflict. The author, in a scholar-reporter capacity, formulated a report attributing meaning to this consultative process. As such a report could have been formulated according to alternative paradigms, methodological approaches and theoretical frameworks, the analysis of the adopted framework highlights how different approaches can bias the interpretation of the process and prospects for change. Realist-based conservative interpretations emphasise 'official' decision-making processes where legitimacy is expressed through political and legal frameworks based on precedent. Idealist-based interpretations emphasise that circumstances entailing significant conflict warrant equal consideration being given to 'non-official' 'resolutionary' problem-solving processes where conflict is treated as a catalyst for learning and outcomes are articulated as understanding generated about conflict and how different strategies can transform it. The developed integrated framework approach establishes the independence of scholarly reporting. Its purpose goes beyond perpetuating scholarly debate about alternative 'objective' understandings of conflict; it focuses primarily on communicating a more inclusive understanding of the contradictions inherent in a particular conflict. It increases the capacity to understand when, where, why and how conflict precipitates social change, and articulates possibilities for reconceptualising what might be the more sustainable direction of change.

By the adoption of Integrated Water Resource Management (IWRM), South Africa has significantly changed its water management regime and the institutions governing water in this country. These changes were first introduced by the National White Policy Paper on Water in South Africa in 1997 and subsequently the National Water Act in 1998. One of the key components of IWRM is the decentralisation of water management to a regional or catchment level and the introduction of public participation in the water management sector. With the enactment of the NWA South Africa incorporated IWRM in its legal system and a decade on, authorities are now turning to its implementation. The NWA introduces Catchment Management Agencies (CMAs) in water management and gives them authority over water management at a catchment level. Initially there were nineteen (19) and this number has since been reduced to nine (9) due to a number of factors. South African authorities are now seeking ways in which they can effectively decentralise water to a catchment level, including delegating and assigning some of the functions currently held by the Minster to CMAs. Using Victoria, Australia as a comparative study, this study investigates how water management can best be decentralised to a catchment level; it starts off by investigating the theory of decentralisation and its pros and cons; then sets off to investigate water management has been decentralised in Australia from the national level, to state level and catchment level; it then investigates the role of Rural Water Authorities in Victoria and compares them to Catchment Management Agencies in South Africa. Finally the work highlights the water management regime and the various stakeholders in water management South Africa from a national level to a catchment level and the challenges facing South Africa in term of WRM; and then makes recommendations and a conclusion based on its research findings and the South African socio-economic and political context.

The impress of history has been particularly profound in the sphere of environmental perception, in that South Africans, both black and white, have had their notions of the environment shaped by the political forces of the past. Accordingly, this study is placed within the context of historical geography, as its open-ended techniques and multi-disciplinary approach is regarded as the most appropriate way of undertaking a study which crosses both historical and environmental boundaries. A contention fundamental to this study, is that South African environmental awareness and knowledge is at a fairly low level and that black environmental interest and concern in particular, ranges from apathy to outright hostility. It is further contended that the attainment of mass environmental literacy is essential for the success of the environmental movement in this country and that this in turn, is dependent on the adoption of a strategy incorporating an integrated historical, social and political perspective. Historico-political factors such as: the impact of the colonizing process; the dispossession of the indigenous peoples; the effect of racial attitudes; discriminatory land legislation and, in particular, the imposition of the apartheid system in 1948, are evaluated in terms of their effect on the development of black environmental attitudes. The culmination of these factors has led to a distortion of environmental perceptions and attitudes, as well as to the alienation of blacks from the environment. Conversely, the initially exploitative white response to the environment gradually incorporated a preservationist element, subsequently evolving into a conservation ideology which generally ignored black interests and perspectives. The policies and activities of the first black environmental organizations are detailed, in an attempt to place their achievements in historical perspective. Research in this area was conducted using primary sources. Interviews with selected environmental and mass democratic organizations in the Greater Cape Town Region were conducted. Using the techniques of the focused interview, their stance on environmental issues was established and their proposals for a future environmental strategy elicited. It was found that, while only one of the nine mass democratic organizations evaluated had an environmental policy, they were all committed to the establishment of a democratic society as well as to the concept of mass participation in environmental politics. Based on the insights gained from the historical aspects of the study, as well as an assessment of the proposals put forward during interviews, it is concluded that certain preconditions .are necessary for the successful implementation of future environmental strategies, if blacks are to become involved in environmental issues. These are: the destruction of apartheid; the establishment of a democratic state and the enhancement of individual quality of life.

In response to growing concerns over wetland habitat loss and the associated impact on water resources, federal and state legislation has been enacted to protect vulnerable wetland habitats from the impacts of humans. In order to examine the efficacy of current coastal resource policy and its implementation, a study was conducted in Mount Pleasant, South Carolina, a coastal city of the Atlantic, focusing on the quantification of wetland habitat change over time within a specific area of interest. The study incorporated an assessment of the effects of escalating population pressures and subsequent urban development on local wetland habitats due to the inherent threat of habitat degradation resulting from negligent development practices. The research methodology included a series of stakeholder interviews conducted within the Mount Pleasant community in order to define the key players who shape coastal resource policy formation, implementation, and enforcement. Further, a spatial analysis examined land use change over time. A historical record of regional land use derived from remotely sensed satellite imagery enabled the measurement of land use change over time. The results of a change detection analysis indicate an acceleration of wetland habitat loss in the second decade chosen for analysis in spite of strengthened coastal resource regulations enacted within the same time period. These results support a need for improved regulatory enforcement strategies and utilization of conservation-driven development practices.

Lead in soil has been shown to be a significant pathway of lead exposure in children. Several factors including age of housing units, exterior composition, and paint loading may affect the amount of lead present in the soil. The purpose of this study was to analyze soil lead levels on properties located in an historic district and relate those levels to the variables previously mentioned. A total of 30 soil samples were collected from housing units in a nationally recognized historic district. Concentrations of lead in the soil were analyzed using a NITON X-ray Fluorescence Spectrum Analyzer, following EPA Method 6200 and the instrument protocol. Significant differences were found between the soil lead levels and paint loading (fully painted vs. non-painted). Significant differences were also found between soil lead levels and exterior surface (frame, brick, and other). A correlation analysis revealed there was no correlation between housing age and soil lead levels. Soil lead can be used as a predictor of blood lead levels in children. Using the information regarding soil lead concentration, the relative risk of exposure to lead and the subsequent health effects can be estimated for children living in the study area. The results from this study can also be used to initiate other studies and develop educational strategies for the district.

Healthy riparian vegetation has a positive impact on the adjacent river. Unfortunately, riparian vegetation is often threatened by human impacts such as dam construction and clearing. To gain the knowledge underlying the effects of such impacts and to aid riparian rehabilitation, the objective of this thesis was: to determine riparian vegetation association with, and response to, variation in fluvial geomorphology over several scales and consequently to fluvial disturbance. Only woody riparian plant species were considered. Flood disturbance was the unifying theme of this thesis. Linked to this theme and arising from the main objective was the supposition that plant interactions with the abiotic environment, but not biotic interactions between species, control riparian species distribution because of frequent fluvial disturbances. Woody riparian vegetation and riverine environmental variables were recorded along the upper Murrumbidgee River at three spatial scales based on a geomorphic hierarchy for Chapter 2. Multivariate analysis was used to group species and to associate environmental variables with vegetation at the three spatial scales. Observations at the two larger scales, of river segment (site) and riparian reach (transect), identified a river-longitudinal speciescomposition gradient associated with geology, river width and stream channel slope. Observations at the smallest scale of geomorphic units (plot) identified a lateral riparian gradient and also the longitudinal gradient; these gradients were associated with geomorphic variation, land use, plot elevation and also river longitudinal variables. Using the same data set, but varying the spatial scale of analysis caused the species composition pattern to change between scales. Increase in scale of observation, that is from geomorphic unit to reach and segment scales, resulted in disproportionate importance of rarer species and decreased importance of some key riparian species at the larger scales. It would appear that in this instance the geomorphic unit scale best described patches of different species composition because this scale had high spatial resolution and was also able to identify multiple gradients of environmental variation. It was recommended that riparian sampling take place at scales that represent dominant gradients in the riparian zone. These gradients are represented by geomorphic scales, indicating the appropriateness of using geomorphic based scales for observation of riparian vegetation. Chapter 3 considered whether there is a geomorphic template upon which riparian vegetation is patterned and whether it is associated with process variables, such as flooding and soil type. This question was investigated at different spatial scales in three ways: i) by an experiment to determine whether soil nutrient condition affects plant growth; ii) by graphical analysis of trends between geomorphic units, species and process variables; and iii) by analysis of vegetation distribution data. The smallest scale (meso) found experimental differences in plant growth because of soil type. Plants growing in sand had the lowest performance, with an average plant Relative Growth Rate (RGR) of 0.01, compared to plants growing in soils with small amounts of silt or clay particles, with an average plant RGR of 0.04. This pattern was attributed to differences in nutrients. Clear relationships were demonstrated at the larger geomorphic unit scale between species distribution and process variables. For example, hydrology and substratum type were found to be associated with geomorphic units and species. The largest scale considered in Chapter 3 was the riparian reach scale. At this scale species were clearly grouped around reach type. Therefore, geomorphology was considered to be a template for riparian species distribution. Findings in this chapter suggested that geomorphic variables should be good predictors of riparian species distribution. This hypothesis was tested and supported in Chapter 6. The experiments reported in Chapter 4 aimed to determine whether inundation depth and duration affected plant performance and survival for five common riparian zone species. Riparian seedling patterns in the field were also compared with experimental results to test whether species performance was reflected by field distribution. The experiments that were conducted included an inundation period and depth experiment, and a survival period test whilst under complete inundation. Biomass and height relative growth rates were determined, and the results were analysed using factorial Analysis of Variance. Obligate riparian species (Callistemon sieberi, Casuarina Cunninghamiana, Leptospermum obovatum) were found to be tolerant of inundation duration and depth, to the point where inundation provided a growth subsidy. On the other hand, non-obligate riparian species (Acacia dealbata, Kunzea ericoides) were either just tolerant of inundation or showed a negative growth response. For instance, C. sieberi demonstrated an average height RGR of 0.04 after complete inundation and 0.007 when not inundated, while A. dealbata had an average height RGR of 0.001 after complete inundation and 0.01 when not inundated. These experimental findings were found to closely reflect both seedling and adult plant distribution in the field such that inundation tolerant species were found close to the river and intolerant species further away. Thus, the conclusion was drawn that riparian species establishment and distribution is affected by inundation and that change to the flood regime could have serious impacts on riparian zone plant composition. The other aim of this chapter was to determine whether optimum germination temperatures were associated with flood or rainfall. Growth chamber germination trials were conducted at air temperatures of 15�C, 20�C and 25�C to determine the 'best' germination temperature. These germination patterns at different temperatures were then related to annual variation in field temperature, flooding period and rainfall. No evidence was found to suggest a relationship between ideal germination temperature and flood season, rather it was suggested that germination was patchy through time and may simply reflect recent rainfall. Investigations that were reported in Chapter 5 aimed to elucidate relationships between species and flow velocity variables. Two experiments were conducted: i) a flume experiment to determine the effect of flow velocity on plant growth; and ii) an experiment to observe the response of plants to damage (imitating flood damage) and inundation. Field observations of species distribution and flow velocity related variables were also conducted to put the flume results into a real-world context. Treatments for the flume experiment were fast flow velocity (0.74 m s-1), slow velocity (0.22 m s-1) and no velocity (control) but still inundated. All treatments were flooded completely for four days. Subsequent biomass and height relative growth rates were determined, and the results were analysed using factorial Analysis of Variance. Results were unexpected, given that obligate species exposed to the fastest velocity had the highest growth rate with an average height RGR of 0.046, compared to plants in still water, which grew the least with an average height RGR of 0.013. It was hypothesised that this response was because relatively greater carbon dioxide and oxygen levels were available in the moving water compared to the still water. With regard to shoot damage, the species that were nonobligate riparian species lost more leaves from velocity treatment than the obligate riparian species. The cut and flood experiment found growth of the obligate species (Casuarina cunninghamiana) to be greater after cutting than the non-obligate species. Flooding was not found to have an effect in the cut and flood experiment, probably because the period to sampling after flood treatment was longer (4 weeks) than other flooding experiments (3 weeks). Field observations were found to support the experimental findings, with a gradient of species across the riparian zone that reflected potential flood velocities. Therefore, velocity is one of a suite of riparian hydrological factors that are partially responsible for the gradient of species across the riparian zone. Potentially the absence of flooding could result in a homogeneous mix of species, rather than a gradient, except on the very edge of the river. The study that was reported in Chapter 6 investigated a technique for predicting riparian vegetation distribution. One of the aims of this investigation was to address a current riparian rehabilitation shortfall, which was how to objectively select species to plant for rehabilitation. Field data were collected from three confined river valleys in south-eastern New South Wales. Using data on plant species occurrence and site and plot measures of soils, hydrology and climate, an AUSRIVAS-style statistical model, based on cluster and discriminant analysis, was developed to predict the probability of species occurrence. The prediction accuracy was 85 % when tested with a separate set of plots not used in model construction. Problems were encountered with the prediction of rarer species, but if the probability of selection was varied according to the frequency of species occurrence then rarer species would be predicted more often. Various models were tested for accuracy including three rivers combined at the geomorphic unit (plot) scale and riparian reach (transect) scale in addition to a Murrumbidgee River plot scale model. Surprisingly, the predictive accuracy of the all rivers and single river models were approximately the same. However, the difference between the large scale and small scale models pointed to the importance of including small scale flood-related parameters to predict riparian vegetation. When these riparian predictions were compared to predictive outcomes from a hill slope model, which was assumed to be affected by fewer disturbances (i.e. flooding), predictive accuracies were not very different. Overall though, predictive accuracy for riparian vegetation was high, but not good enough to support the supposition that riparian vegetation is abiotically controlled because of frequent flood disturbance. Nevertheless, geomorphology and consequently flood effects are still important for the determination of the riparian community composition. Overall, riparian vegetation was found to be closely linked to its environment (evidenced in Chapters 2, 3, 4, 5) in a predictable manner (Chapter 6). Species pattern relied on flood disturbance affecting species distribution. Some riparian species were found to be highly tolerant of flooding and gained a growth advantage after flooding (Chapters 4 and 5). Therefore, flood tolerance was important for the formation of a species gradient across the riparian zone. These species tolerances and growth requirements reflect riparian geomorphic pattern (Chapter 3), which was suggested to form a template on which riparian vegetation is structured.

[Truncated abstract] Currently, Alcoa World Alumina Australia (Alcoa) mines and undertakes procedures to rehabilitate approximately 550 ha of jarrah forest each year at two open-cut bauxite mines in South-West Western Australia. Alcoa aims to establish a self-sustaining jarrah forest ecosystem that maintains the functions of the landscape prior to mining, including biodiversity, on areas that have been mined for bauxite. Indigenous terrestrial orchids form a significant proportion of the indigenous geophytic plant species that either fail to colonise rehabilitated areas or do so very slowly. Terrestrial orchids are considered to be particularly sensitive to competition from weeds and disturbance, which combined with the obligate nature of the orchid-mycorrhizal fungus association suggests that orchids would colonise rehabilitation areas only when both microhabitat sites and soil microflora have established. Occurrence of certain orchids may therefore be expected to be useful as indicators of ecosystem health, the success of vegetation establishment and the recovery of edaphic conditions suitable for orchid mycorrhizal fungi. Vegetation surveys were undertaken to compare orchid species richness and population size of a chrono-sequence of rehabilitation areas with adjacent unmined forest. ... Orchid taxa present in each vegetation assemblage were generally not exclusive to these assemblages, with the following broad exclusions: D. bracteata was found only in species assemblages associated with rehabilitation areas; and Eriochilus sp. and T. crinita were found only in species assemblages associated with unmined forest. No single orchid species appears to be an indicator of ecosystem recovery. However, the presence of populations of C. flava, P. sp. crinkled leaf (G.J.Keighery 13426) or P. recurva in combination with the absence of the disturbance opportunist orchid taxa D. bracteata and M. media appears to be a measure of the maturity of the rehabilitation vegetation. Orchid species richness and clonal orchid population size were correlated with changes in vegetation structure, but apart from the absence of orchids in 1 year old rehabilitation areas, these orchid population characteristics did not show any direct relationship with rehabilitation age or vegetation maturity. Only two orchid taxa appeared to have potential as indicators of vegetation characteristics: T. crinita as an indicator of undisturbed jarrah forest; and D. bracteata as an indicator of disturbed ecosystems. The results of this study suggest that most jarrah forest orchid taxa will readily colonise the post bauxite mining landscape, but that the unassisted colonisation by recalcitrant orchid taxa may be a prolonged process. It is recommended that field-based transplantation and/or seeding trials be undertaken with these recalcitrant taxa to determine if these procedures will enhance recruitment. The results of this work have applications not only in the management of post-mining landscapes but also in vegetation monitoring and conservation work in Western Australia and elsewhere.
