This research project aims to develop the theory and application of integrated landscape restoration in a fragmented agricultural region - the Mt. Lofty Ranges of South Australia. Spatially explicit priorities will be set for the type and location of habitat to be restored for the benefit of the natural biodiversity within a physical environmental, economic and social context. Heuristic and optimisation models will be created within a Geographic Information System (GIS) and assessed for their ability to set such priorities in integrated landscape restoration. The techniques will help sustain ecological, physical and human systems in many other over-cleared regions.Read moreRead less
Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity a ....Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity and function of coastal seascapes is to be conserved. This project aims to use a combination of novel modelling, surveys, and large experiments to understand how threatened seagrass, fish, and sediment habitats are altered in human modified seascapes, and to assess the success of habitat restoration following the removal of boating structures.Read moreRead less
Demonstrating the impacts of ground tank closure on biodiversity and landscape function in southeast Australian rangelands. Despite incentives for improving biodiversity outcomes in pastoral landscapes pastoralists are resistant to strategic tank closure. Research will monitor the effects of total-closure, partial-closure and fencing of ground tanks on biodiversity. Results of research will be built into a model to assist land managers in decision making. The research will be conducted in conjun ....Demonstrating the impacts of ground tank closure on biodiversity and landscape function in southeast Australian rangelands. Despite incentives for improving biodiversity outcomes in pastoral landscapes pastoralists are resistant to strategic tank closure. Research will monitor the effects of total-closure, partial-closure and fencing of ground tanks on biodiversity. Results of research will be built into a model to assist land managers in decision making. The research will be conducted in conjunction with land management authorities thus outcomes can be readily passed on to relevant user groups. The project will aid in the adoption of sustainable land management practices in relation to total grazing pressure and biodiversity. The research within arid woodland and shrubland communities is applicable to a large area of Australia's rangelands.Read moreRead less
Increasing sandalwood (Santalum spicatum) recruitment in regional Western Australia through mammal conservation. The highly prized sandalwood is the basis of an industry that employs over 100 people and generates $12 million export income annually in regional WA. Natural recruitment of sandalwood is poor.

The highly prized sandalwood is the basis of an industry that employs over 100 people and generates $12 million export income annually in regional WA. Natural recruitment of sandalwood is poor. This project will build on research, conducted by Murdoch University and the Forest Products Commission, that indicates natural recruitment of the tree is greatly enhance in the presence of native rat-kangaroos who cache the seeds. This project will train an APA(I) postgraduate through an industry based project that will evaluate increased recruitment of sandalwood by native mammal caching. Many of these mammals are Conservation Dependent or Threatened with extinction.Read moreRead less
Achieving biodiversity conservation and ecosystem service delivery: the role of landscape structure. Achieving gains for human well-being and, at the same time, conserving biodiversity is the ultimate challenge for conservation policy. This project will develop new understandings and new methods to address this issue, with important impacts on the effectiveness of strategies to conserve biodiversity.
Unlocking the secrets of mangrove conservation success. This project aims to address the deterioration of mangrove ecosystems. Mangroves support fisheries, shoreline protection and carbon sequestration. The project aims to identify social-economic conditions that enable effective conservation in mangroves over multiple spatial scales.

This project aims to address the deterioration of mangrove ecosystems. Mangroves support fisheries, shoreline protection and carbon sequestration. The project aims to identify social-economic conditions that enable effective conservation in mangroves over multiple spatial scales. The project will use state of the art datasets and innovative modelling approaches to understand how factors such as population, governance and access to markets influence changes in mangrove extent and restoration success. Expected outcomes include implementation of more effective environmental programs in Australia and overseas. This should provide significant benefits, including more cost-effective allocation of resources and increased delivery of ecosystem services.Read moreRead less
An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current res ....An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current resources is required, dependent on understanding what factors affect water yield and how they may be better manipulated. This project innovatively integrates ecological and hydrological processes by modelling the expression of water use by vegetation and its management and water availability at fine resolutions.Read moreRead less
Refining Restoration Ecology: Is Range of Historical Variability an appropriate concept to guide ecosystem management and restoration? Ecosystem restoration is an urgent task in many Australian landscapes. Range of Historical Variability (RHV) theory provides an influential but largely untested framework to guide restoration activities. We will test the RHV proposition that biodiversity conservation is enhanced if the structure of altered ecosystems is restored within the pre-settlement range. P ....Refining Restoration Ecology: Is Range of Historical Variability an appropriate concept to guide ecosystem management and restoration? Ecosystem restoration is an urgent task in many Australian landscapes. Range of Historical Variability (RHV) theory provides an influential but largely untested framework to guide restoration activities. We will test the RHV proposition that biodiversity conservation is enhanced if the structure of altered ecosystems is restored within the pre-settlement range. Plants, vertebrates and invertebrates will be compared between ?unrestored? Callitris woodlands dominated by post-settlement regrowth, and ?restored? stands where regrowth has been reduced within the RHV. This will be the first test of RHV theory to encompass a range of taxonomic and functional groups at both local and landscape scales.Read moreRead less
Ecological sustainability and changing land use in the Pilbara. Land use change is frequently associated with large changes in key elements of 'sustainability? ? biodiversity, productivity, and water and nutrient cycles. However, in the Pilbara, fires and flooding rains are so frequent that detecting consequences of land use change is frequently confounded by other ?disturbances?.

Land use change is frequently associated with large changes in key elements of 'sustainability? ? biodiversity, productivity, and water and nutrient cycles. However, in the Pilbara, fires and flooding rains are so frequent that detecting consequences of land use change is frequently confounded by other ?disturbances?. We aim, through controlled field experiments, to disentangle effects of land use change (e.g. de-stocking of rangelands, altered water availability through mining activity or infrastructure) from those of natural disturbance and variability (both spatially and temporally). This research will improve understanding of key areas in resilience of rangelands and of major processes that are critical for sustainable management.Read moreRead less
