"The dissertation brings together discourses relating to sustainability with that of the environment, at least in terms of its meaning and responses to it being culturally constructed. The Central Adelaide Hills provides the locality for achieving this, which a peri-urban environment is subject to the power exerted by urban Adelaide as well as the tension arising out of land use conflict and attitudes to the environment."

The loss of habitat and increased spatial isolation of trees in paddocks is predicted to lead to a decline in plant fecundity because of disruptions to plant-pollinator interactions, which has important implications for the long-term persistence and maintenance of these populations. In order to assess the ability of paddock trees to contribute to population regeneration, this study assessed the reproductive viability and patterns of mating of paddock trees of two woodland species, Eucalyptus camaldulensis and E.leucoxylon in the Mt. Lofty Ranges, South Australia. This study revealed that paddock tree populations of E. camaldulensis and E.leucoxylon were reproductively viable and received sufficient visits by pollinators that resulted in high outcrossing rates. The results suggest that seed collected from these paddock trees are both genetically diverse and representative of adult populations. Therefore, such trees could contribute successfully to conservation strategies that sought to regenerate cleared paddocks. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1292793 / Thesis (Ph.D.) -- University of Adelaide, School of Earth and Environmental Sciences, 2007

Includes bibliographical references (leaves 78-86) In the Herrmanns sub-catchment in the Mt. Lofty Ranges (near Mt. Torrens) soil sodicity was the dominant factor in causing clay to disperse in the eroded area along the foot slopes, wheras in non-eroded areas of the mid-slopes and on the stream banks, the dispersive power of sodicity was attenuated by the flocculative power of other soil properties.

This study is concerned with programs to conserve remnant stands of native vegetation in the agricultural regions of South Australia and concentrates on the development of explicit evaluation procedures which reflect stated conservation objectives. As botanical data are available for stands of native vegetation in most of the agricultural regions, stands in a particular region are able to be compared rather than assessed in isolation. Based on a review of conservation evaluation schemes in Australia and overseas, a hierarchical evaluation procedure using multiple criteria to compare stands was applied to stands of vegetation in the Mount Lofty Ranges. The conservation objective, of preserving samples of all plant communities in a region, led to the analysis of existing botanical data from two surveys of the Mount Lofty Ranges, to provide the basis for an inventory of regional plant communities. These surveys included 52 remnant stands of native vegetation and employed a point-centred quarter plotless sampling technique to summarise the vegetation. Numerical classificatory analysis of the raw sampling point data produced a more comprehensive floristic summary than the results from the plotless sampling. These floristic groups were correlated with physical environmental variables to produce an inventory of 45 regional vegetation types, as the first stage in the conservation evaluation of stands. Evaluation criteria of size, species richness and species rarity were quantified and used to select examples of each vegetation type on the basis of overall satisfaction of the criteria. In addition, the smallest suite of stands, in which all the vegetation types were represented, was determined, and was shown to be 24 stands. All of these were included in the 37 stands chosen using the three criteria. A third evaluation stage used stand parameters such as plant community richness to give a priority ranking of the 37 stands. A polythetic divisive classification of the vegetation types was developed to provide a means of evaluating communities in stands of native vegetation yet to be sampled in the region, and of comparing the vegetation types with communities in existing reservesr Examination of species-sampling area relationships led to recommended plot sizes for such future vegetation surveys in the Mount Lofty Ranges. The ease of collecting floristic data and the extensive time involved in quantitative measurements suggest that all perennial plant species be recorded and only estimations be made of vegetation quantity and structure for each sampling plot. This study demonstrates the usefulness of numerical classification techniques for conservation evaluation, and of continuous variables to quantify criteria of conservation value; and the application of those criteria in an explicit, hierarchical conservation evaluation procedure.

Revegetation is required to conserve the biological diversity of over-cleared and fragmented agricultural regions. This dissertation represents an application of spatial information technologies to environmental management. It makes a significant contribution to the integration of general landscape-scale principles into restoration ecology. New and established quantitative, spatial analytical techniques are used in environmental modelling, ecological assessment and in setting geographic priorities for strategic revegetation planning in the Mt. Lofty Ranges in South Australia. This is one of the first assessments of the adequacy and representativeness of remnants in an agricultural region and one of the first attempts to apply these landscape-scale conservation principles to the field of restoration ecology. The adequacy of the remnant ecological system is assessed in terms of the landscape structure. Landscape ecological principles provide a basis for setting geographic priorities for the revegetation of an adequate remnant ecological system. Although seldom quantified, it is often thought that remnants in agricultural regions are not representative of the regional physical environmental heterogeneity. The representativeness of remnant vegetation is assessed in the study area and a complex effect of land clearance and reserve selection on representativeness is revealed which has significant implications for strategic revegetation planning. Land clearance has precluded the use of information on the spatial distribution of biological diversity in agricultural regions. Hence, a surrogate is required in strategic planning for the restoration of a representative regional ecological system. The degree of vegetation/environment convergence is assessed to investigate the viability of using the physical environment as a surrogate for the distribution of biological diversity. An index of coincidence is developed specifically for this purpose. An environmental classification is then derived for use in setting geographic priorities for the restoration of a representative regional ecological system. Three complementary techniques are used to find the simplest classification possible that does not have overly broad environmental classes. Geographic priorities are suggested according to the distribution and representativeness of environment types in the study area. In the light of the results of this dissertation, a research direction for restoration ecology in agricultural landscapes is mapped out. / Thesis (Ph.D.)--Department of Geographical and Environmental Studies; Department of Applied and Molecular Ecology, 2000.

During deposition of the mixed carbonate - clastic sequence of the Mundallio Subgroup, the " Adelaide Geosyncline " was a very shallow, elongate sedimentary basin, flanked to the west and east by older Precambrian basement. In much of the southern and northern Flinders Ranges, clastic deposition predominated in the lower Mundallio Subgroup. In the north, alternating development of shallow mudflats and sandflats ( Nankabunyana Formation ) depended on the interplay between the sediment supply and winnowing processes, while dolomite mudstones were locally deposited in the shallowest areas. In the eastern half of the Willouran Ranges, massive shales were deposited as the environment remained persistently below wave base ( Camel Flat Shale ), but a renewed sand influx led to deposition of the Tilterana Sandstone. In the southern Flinders Ranges, terrigenous clay and silt were deposited on submergent mudflats which shallowed into intermittently exposed dolomite mudflats ( Nathaltee Formation ). Dolomite mudflats were a more persistent feature in areas more distal from the terrigenous source, and sometimes contained isolated, ephemeral lakes which were sites of magnesite deposition ( Yadlamalka Formation ). Dolomite and magnesite mudstone deposition of the Yadlamalka Formation became wide spread in the northern and southern Flinders Ranges in the upper Mundallio Subgroup, as shallowing and retreat of the basin margin led to the formation of semi - isolated lakes, separated and enclosed by exposed carbonate mudflats. The elastics deposited in association with these carbonate mudstones consisted largely of sand sized detritus, probably derived from the reworking of aeolian deposits. In the eastern Willouran Ranges, the greater influx of sand and the slightly deeper, largely submergent environments, led to the deposition of the sandstones, dolomites and siltstones of the Mirra Formation. Because of little clastic influx into the northern Mt. Lofty Ranges, shallow to occasionally exposed environments were largely sites of dolomite deposition ( Skillogalee Dolomite ). To the south, shales were deposited in slightly deeper environments ( Woolshed Flat Shale ), although local dolomite deposition occurred in the Adelaide region ( Castambul Formation, Montacute Dolomite ). In the uppermost part of the subgroup, the area of shale deposition extended northward, encroaching over the dolomite mudflats of the upper Skillogalee Dolomite. Dolomite, occurring largely as mudstones, is the major carbonate mineral present in the Mundallio Subgroup, but magnesite is also widespread. Limestones are not present. The carbonates experienced minor replacement by early diagenetic chert, initially precipitated as both crystalline and amorphous phases. Within the upper Mundallio Subgroup, the preservation of fine details of the detrital texture of dolomite mudstones and peloidal dolomites, and the high Sr contents of dolomites ( largely in the range of 400 - 650 ppm ), suggest that these sediments consisted of Ca - Mg carbonates ( protodolomite, Mg - calcite ) at the time of deposition. Slightly greater recrystallisation of dolomites in the lower Mundallio Subgroup resulted in their lower Sr and higher Mn and Fe contents. Magnesite mudstones may have initially precipitated as hydrated Mg - carbonates. Lithification of surface sediments as a result of subaerial exposure, led to the formation of micritic magnesite. Much of this magnesite was subsequently reworked into intraclastic beds. The carbonate mineralogy of this sequence, and the evidence of only rare sulphates, indicate that the carbonates were precipitated from alkaline, Mg - Ca - C03 waters, with a higher carbonate and lower sulphate content than seawater. / Thesis (Ph.D.)--Department of Geology and Mineralogy, 1980.
