Abstract:
Agricultural landscapes in southern Australia were once dominated by temperate eucalypt woodlands of which only fragmented patches and scattered trees in paddocks remain. This study focuses on the decline of scattered trees in the Mount Lofty Ranges and South East agricultural regions of South Australia. A combination of digitized aerial photography and satellite imagery was used to extend a previous assessment of decline undertaken in the early 1980s and increase the period over which decline was assessed to 58–72 years. A total of 17 049 scattered trees were counted from the earliest time period assessed over 11 sites of which 6 185 trees were lost by 2008 — a 36 % decline. Recruitment of 2 179 trees during this period was evident. Imagery indicates that clearing for agricultural intensification is the primary cause of the decline. A range of management options and policy settings are required to reverse the decline notwithstanding the challenges of implementation at a landscape scale across privately owned land.

Abstract:
Conservation programs for threatened species are greatly benefiting from genetic data, for their power in providing knowledge of dispersal/gene flow across fragmented landscapes and for identifying populations of high conservation value. The endangered southern brown bandicoot (Isoodon obesulus obesulus) has a disjunct distribution range in South Australia, raising the possibility that populations of the subspecies may represent distinct conservation units. In the current study, we used a combination of 14 microsatellite and two mitochondrial sequence markers to investigate the phylogeography and population structure of I. o. obesulus in South Australia and south-western Victoria, with the aim of identifying any potential evolutionarily significant units and management units relevant to conservation management. Our phylogenetic/population analyses supported the presence of two distinct evolutionary lineages of I. o. obesulus. The first lineage comprised individuals from the Mount Lofty Ranges, Fleurieu Peninsula and Kangaroo Island. A second lineage comprised individuals from the south-east of South Australia and south-western Victoria. We propose that these two lineages represent distinct evolutionarily significant units and should be managed separately for conservation purposes. The findings also raise significant issues for the national conservation status of I. o. obesulus and suggest that the current subspecies classification needs further investigation.

Abstract:
Autecological data were collected on southern populations of the yellow-footed antechinus (Antechinus flavipes), during a wider study on the persistence of this species in a highly fragmented landscape of the southern Mt Lofty Ranges, South Australia. Data are presented to provide information on this species in the southern part of its range, to present a comparison with populations in other, more northern regions, and to provide an insight into the species' persistence in a fragmented system. Resulting recapture rates lend support to the presence of a male-biased dispersal strategy, which is the first published indication of such a strategy for the species. New information was also recorded for nest sites, with most sites occurring in tall Xanthorrhoea semiplana tateana, and only 33% found in tree cavities. Other results showed mostly comparable population densities and weights with other, more northern populations. However, differences were apparent with respect to juvenile dispersal behaviour and, to some extent, breeding times. Within-study populations also showed variation with regard to weights, density and breeding times. Forest animals were lighter, were largely of lower population densities, and were generally later breeders than animals that inhabited patches and strips of remnant vegetation. Such differences in weight and density may have been due to favourable 'edge effects' in patches and strips, while variations in breeding times may be due to local climatic or habitat factors. The life-history strategies and tolerance of habitat edges shown by A.�flavipes (presently and historically) provide some explanation for the species' persistence in this fragmented system.

Abstract:
A large-scale, long-term study of the impacts on vertebrates of landscape change and habitat fragmentation is taking place at Tumut in southern New South Wales, south-eastern Australia. Field surveys focus on counting birds within three broad kinds of sites in the study region. These are: (1) A randomized and replicated set of 85 sites in remnants or fragments of native Eucalyptus forest located within the boundaries of the Radiata Pine plantation. (2) Sites dominated by Radiata Pine plantation trees (N = 40 sites). (3) Sites in the large areas of continuous Eucalyptus forest adjacent to the plantation that act as “controls” (N = 40 sites). We list of birds recorded during 1996 and 1997. A total of 92 species from 34 families was recorded. The list will be useful for workers examining bird responses to fragmented landscapes as well as those interested in the biodiversity values of plantation landscapes.

Abstract:
Two large-scale, long-term biodiversity monitoring programs examining vertebrate responses to habitat fragmentation and landscape change in agricultural landscapes are taking place in the Murray Catchment Management Area of New South Wales, south-eastern Australia. Field surveys involve counting reptiles under a range of management conditions and across a broad range of vegetation types in two bioregions, the South-western Slopes of New South Wales and the Riverina. We list reptiles recorded during surveys conducted between 2002 and 2009. We include additional species recorded between 1997 and 2009 from a conservation reserve. Thirty-nine species from nine families were recorded. The list will be useful for workers interested in reptile zoogeographical distributions and habitat associations as well as those interested in the biodiversity value of remnant vegetation and tree plantings in fragmented agricultural landscapes.

Full text
Abstract:
This paper describes the South Australian distribution of the southern brown bandicoot (Isoodon obesulus obesulus) on the basis of records of its past occurrence and field surveys undertaken to determine its present distribution. Since European settlement I. o. obesulus has been recorded from four separate regions of the state: the Mount Lofty Ranges, the South East, Kangaroo Island and Eyre Peninsula. Subfossil remains show that I. o. obesulus also once occurred on Yorke Peninsula but there is no evidence that it has existed there in modem times. Field surveys conducted between 1986 and 1993 confirmed that I. o. obesulus still exists in the Mount Lofty Ranges, the South East and on Kangaroo Island. Its status on Eyre Peninsula is uncertain. Isoodon o. obesulus is vulnerable in the South East and Mount Lofty Ranges because of habitat fragmentation and predation by feral carnivores. The Kangaroo Island population is less threatened as large areas of habitat have been preserved and the fox (Vulpes vulpes) has not been introduced. The area of potential bandicoot habitat remaining in these three regions totals approximately 190 000 ha, most of which is already managed for nature conservation. This habitat is highly fragmented, occurring as small remnant patches of native vegetation separated by extensive tracts of cleared and modified land cover. The implications of this habitat configuration for the long-term survival of I. o. obesulus are discussed.

Abstract:
The received wisdom was and is that landscapes cannot be more than a few millions of years old. Nevertheless, consideration of local geology and age of sediments in adjacent basins convinced Paul S. Hossfeld that the summit surface of low relief preserved on the northern Mount Lofty Ranges of South Australia resulted from long-continued planation and that it is of Cretaceous age; that is, some 70 million years old. Hossfeld's apparently intuitive suggestion that very old landscapes exist, recorded in his graduate thesis but not further pursued by him, is the earliest known statement of this idea.

Abstract:
Many species of reptiles are sedentary and depend on ground-layer habitats, suggesting that they may be particularly vulnerable to landscape changes that result in isolation or degradation of native vegetation. We investigated patterns of reptile distribution and abundance in remnant woodland across the Victorian Riverina, south-eastern Australia, a bioregion highly modified (>90%) by clearing for agriculture. Reptiles were intensively surveyed by pitfall trapping and censuses at 60 sites, stratified to sample small (<30 ha) and large (>30 ha) remnants, and linear strips of roadside and streamside vegetation, across the regional environmental gradient. The recorded assemblage of 21 species was characterised by low abundance and patchy distribution of species. Reptiles were not recorded by either survey technique at 22% of sites and at a further 10% only a single individual was detected. More than half (53%) of all records were of two widespread, generalist skink species. Multivariate models showed that the distribution of reptiles is influenced by factors operating at several levels. The environmental gradient exerts a strong influence, with increasing species richness and numbers of individuals from east (moister, higher elevation) to west (drier, lower elevation). Differences existed between types of remnants, with roadside vegetation standing out as important; this probably reflects greater structural heterogeneity of ground and shrub strata than in remnants subject to grazing by stock. Although comparative historical data are lacking, we argue that there has been a region-wide decline in the status of reptiles in the Victorian Riverina involving: (1) overall population decline commensurate with loss of >90% of native vegetation; (2) disproportionate decline of grassy dry woodlands and their fauna (cf. floodplains); and (3) changes to populations and assemblages in surviving remnants due to effects of land-use on reptile habitats. Many species now occur as disjunct populations, vulnerable to changing land-use. The status of reptiles in rural Australia warrants greater attention than has been given to date. Effective conservation of this component of the biota requires better understanding of the population dynamics, habitat use and dispersal capacity of species; and a commitment to landscape restoration coupled with effective ecological monitoring.

Abstract:
Woodland birds are declining throughout the agricultural landscapes of south-eastern Australia, but the specific mechanisms driving these declines remain unclear. Reproductive failure via clutch depredation could conceivably contribute to these declines. Although site-scale habitat may influence the risk of clutch failure, larger-scale influences, such as whether a landscape contains a rural town or not (‘landscape type’), may also play a role. This study monitored artificial open-cup nests deployed in three pairs of the two landscape types and: 1) indexed clutch survival and predator assemblage; and 2) determined if clutch survival was influenced by landscape type and/or local habitat characteristics. High levels of clutch depredation were observed in both landscape types and for all landscapes, with no evidence to suggest that landscape type or habitat characteristics influenced clutch survival or the time-to-first-predator visit. Predator assemblage also was consistent between landscape types. Generalist avian predators were the most common egg predators. Such egg predators may be ubiquitous throughout the fragmented Box-Ironbark woodlands of south-eastern Australia.

Abstract:
Biodiversity conservation throughout the world is challenged by the impacts of a changing climate on fragmented landscapes. To mitigate these threats, conservation managers require models which can demonstrate the consequences of both negative impacts and management actions. This need can be addressed through spatial modelling applications. Unfortunately, throughout much of the world, spatial modelling is forgone, being seen as requiring skills and resources beyond the means of many conservation planners and managers. This thesis seeks to address this dilemma by delivering criteria for a successful modelling application and by providing case studies which demonstrate how appropriate modelling can be undertaken without highly specialised skills or prohibitively expensive software and equipment. In this way it facilitates the delivery of better targeted and, consequently more effective, management actions. For my case studies I have used the south-western corner of Australia as a demonstration landscape. This region is recognised internationally as a “biodiversity hotspot,” not only for the biological richness and uniqueness of species but also for the level of threat to which they are subject. Like many landscapes throughout the world, much or this region’s natural biota exists in fragmented, fragile and degraded patches and is therefore highly vulnerable to the anticipated impacts of anthropogenic global warming. In this thesis I have: 1) examined the principles of spatial modelling and reviewed how spatial modelling has been applied to conservation management in this region, 2) conducted examples of different forms of spatial modelling using actual regional conservation management issues, and 3) demonstrated how these examples can be incorporated into conservation management planning. My key findings are: Spatial modelling provides users with an opportunity to effectively test hypotheses, thereby informing the planning process and improving conservation outcomes. Where spatial modelling is omitted from the process, knowledge gaps are often addressed by the axiomatic and by assumption. This is contrary to the principles of effective adaptive management. Modelling tools are inherently more effective when selected for their capacity to meet a planning objective rather than where projects are tailored to meet a model’s capacity. The coordinated use of multiple tools can often provide a more robust understanding of the consequences impacts and mitigating actions. All tools and data sets used should be utilised with a clear and acknowledged understanding of their suitability, strengths and limitations. A wide range of spatial modelling tools (and data sets) are freely and readily available to conservation managers. Most of these come with excellent tutorials and support services. Data gaps can often be addressed through targeted field observations, obtained through complimentary planning processes, or synthesised from accessible data sets. There is a very large body of peer reviewed literature demonstrating means by which others have applied existing modelling tools, or developed tools themselves, to meet a wide range of applications. Accessing this literature is an excellent means of building spatial modelling capacity. New and improved tools, methodologies and data sets are constantly being developed. A failure to implement effective spatial modelling is becoming increasing difficult to justify.
