Do dingoes regulate the structure of arid ecosystems? Predation by the red fox and land degradation due to overgrazing have been identified as major factors contributing to the loss of biodiversity in arid Australia. I hypothesise that dingoes by regulating populations of foxes and herbivores may have positive effects on biodiversity. If this hypothesis is supported, this project will have great significance for biodiversity conservation and is likely to irrevocably change land and wildlife man ....Do dingoes regulate the structure of arid ecosystems? Predation by the red fox and land degradation due to overgrazing have been identified as major factors contributing to the loss of biodiversity in arid Australia. I hypothesise that dingoes by regulating populations of foxes and herbivores may have positive effects on biodiversity. If this hypothesis is supported, this project will have great significance for biodiversity conservation and is likely to irrevocably change land and wildlife management practices in Australia. The recommendations arising from this research will influence policy on land management and contribute to achieving an environmentally sustainable Australia.

Integrating the conservation and ecosystem-service value of Australia's catchments. This project addresses the Priority Goal of Sustainable Use of Biodiversity by explicitly linking the intrinsic value of biodiversity and supporting ecosystems with the services they provide to humanity (e.g. carbon storage and nutrient cycling). It will employ a comprehensive, innovative approach to integrating conservation, market and non-market values of land holdings in Australia's catchments using the concep ....Integrating the conservation and ecosystem-service value of Australia's catchments. This project addresses the Priority Goal of Sustainable Use of Biodiversity by explicitly linking the intrinsic value of biodiversity and supporting ecosystems with the services they provide to humanity (e.g. carbon storage and nutrient cycling). It will employ a comprehensive, innovative approach to integrating conservation, market and non-market values of land holdings in Australia's catchments using the concept of nature's services. Through extensive collaboration among leading scientists and land managers, the project will identify sites of high value requiring special attention, yield important theoretical advancements to how we value ecosystems, and provide practical and easily applied guidelines for land managers.

Designing landscapes to deliver ecosystem services to agriculture. This project addresses the Priority Goal of Sustainable Use of Biodiversity by employing a pioneering management framework that identifies situations where agriculture can gain maximum benefit from nature's services. Services like pollination are crucial; approximately 35% of global food production comes from crops pollinated by bees or birds. These services contribute billions of dollars to production.

This project addresses the Priority Goal of Sustainable Use of Biodiversity by employing a pioneering management framework that identifies situations where agriculture can gain maximum benefit from nature's services. Services like pollination are crucial; approximately 35% of global food production comes from crops pollinated by bees or birds. These services contribute billions of dollars to production. Our model will greatly enhance the flow of services from nature to agriculture by linking land-use options with service availability. This will improve economic returns to local communities and agricultural industries, and promote protection of native species by recognising their contribution to agriculture. Read moreRead less
Spatial-dynamic models to identify optimal fire mosaics, based on demography, dispersal and fire responses of plants, birds and reptiles. Inappropriate fire regimes threaten native species with extinction. The threat is higher in cleared landscapes where habitat is isolated and recolonisation unlikely. Furthermore, climate change is predicted to increase the frequency of intense bushfires. To meet the priority goals Sustainable Use of Biodiversity, and Responding to Climate Change, landscape-sca ....Spatial-dynamic models to identify optimal fire mosaics, based on demography, dispersal and fire responses of plants, birds and reptiles. Inappropriate fire regimes threaten native species with extinction. The threat is higher in cleared landscapes where habitat is isolated and recolonisation unlikely. Furthermore, climate change is predicted to increase the frequency of intense bushfires. To meet the priority goals Sustainable Use of Biodiversity, and Responding to Climate Change, landscape-scale fire management is essential. We will use simulation models based on detailed biological data and fire-behaviour to explore large-scale and long-term consequences of alternate fire management policies. Our project will enable fire mosaics to be implemented that maintain biodiversity and will identify effective fire management responses to climate change, and habitat fragmentation.Read moreRead less
PLAGA: Pastoral Lease Assessment using Geospatial Analysis. This project improves the capacity of Natural Resource Management (NRM) and land administration agencies to record, monitor and communicate changes in land condition across the large spatial scales characteristic of rangelands. Pastoralists also benefit through improved capacity to promote, defend, understand and if necessary change their management activities on the basis of scientific data.

This project improves the capacity of Natural Resource Management (NRM) and land administration agencies to record, monitor and communicate changes in land condition across the large spatial scales characteristic of rangelands. Pastoralists also benefit through improved capacity to promote, defend, understand and if necessary change their management activities on the basis of scientific data. By further developing and operationalising this new approach to rangeland monitoring in a project integrating human extension expertise, specifically prepared monitoring products, and the associated software, the project will confirm the benefits that satellite technology can provide to land administrators and the grazing industry in monitoring and sustainably managing rangelands.Read moreRead less
A new hypothesis for the development of hollows in Box-Ironbark forest. Timber harvesting in Box-Ironbark forest over the past 150 years has significantly affected the habitat of hollow dependent fauna. Current management aims at speeding the growth of trees to accelerate hollow formation. Recent studies suggest that hollows form in trees of the Box-Ironbark forest following basal stem damage by fire or windstorm, rather than from branch damage as previously assumed. This hypothesis will be t ....A new hypothesis for the development of hollows in Box-Ironbark forest. Timber harvesting in Box-Ironbark forest over the past 150 years has significantly affected the habitat of hollow dependent fauna. Current management aims at speeding the growth of trees to accelerate hollow formation. Recent studies suggest that hollows form in trees of the Box-Ironbark forest following basal stem damage by fire or windstorm, rather than from branch damage as previously assumed. This hypothesis will be tested in relation to wildfires in 1985, 1991 and 1993 and by experimental simulation of these events. The results of this research are likely to have major implications for the management of Box- Ironbark forests.Read moreRead less
Assessing long term change in rangeland health and building models for change, using historical photos and monitoring data. Long-term photo sites and vegetation data will be used to make an assessment of change over the last few decades in the arid pastoral rangelands of Western Australia.
The aims are to: make a judgement about whether the changes have been positive or negative (for particular value systems); make a case for causality; explore links between vegetation data and soil surface, ....Assessing long term change in rangeland health and building models for change, using historical photos and monitoring data. Long-term photo sites and vegetation data will be used to make an assessment of change over the last few decades in the arid pastoral rangelands of Western Australia.
The aims are to: make a judgement about whether the changes have been positive or negative (for particular value systems); make a case for causality; explore links between vegetation data and soil surface, biodiversity and remotely-sensed data; and contribute to the building of models of expected change.
Outcomes will include the meeting of national and international conventions and strategies, and an increased ability of the pastoral industry to access international markets.

Restoring riverine ecosystems: effective model-based planning and monitoring. Australia's riverine ecosystems are considerably degraded and require efficient and immediate attention to restore them to a sustainable condition. Restoration activities at all levels will benefit from the development of a robust framework that will improve understanding of restoration responses at both species and ecosystem levels. This will in turn enhance substantially the ability of managers of restoration project ....Restoring riverine ecosystems: effective model-based planning and monitoring. Australia's riverine ecosystems are considerably degraded and require efficient and immediate attention to restore them to a sustainable condition. Restoration activities at all levels will benefit from the development of a robust framework that will improve understanding of restoration responses at both species and ecosystem levels. This will in turn enhance substantially the ability of managers of restoration projects to identify realistic goals and provide a context for rigorous evaluations of the effectiveness of management interventions. This will result in scarce resources for conservation being directed to efforts with the greatest ecological benefits for stressed Australian lowland rivers.Read moreRead less
Management of rehabilitated bauxite mines to accelerate the return of vertebrate fauna. This project will examine the effect of thinning and burning mine-site rehabilitation on the abundance of terrestrial mammals and reptiles.

This project will examine the effect of thinning and burning mine-site rehabilitation on the abundance of terrestrial mammals and reptiles. This nationally significant project will provide Resource Managers in Western Australia with measures of impacts of forestry thinning and burning (for timber production and drinking water catchment) on vertebrates, and will provide management tools to conserve biodiversity within productive forest environments. Expected outcomes are procedures to accelerate returns of vertebrate fauna to mine-sites, measurements of thinning and burning practices on tree-health, and trial procedures for forest thinning (the 12000 Ha Wungong catchment) that minimise impacts on terrestrial vertebrates.Read moreRead less
Unravelling community interactions between mammals and fungi, and the role of mycophagy in mediating biodiversity and driving ecosystem processes. Maintenance of Australia's forest biodiversity and healthy forested ecosystems are of national importance.

Maintenance of Australia's forest biodiversity and healthy forested ecosystems are of national importance. Mammal species that are key to dispersing beneficial fungi in our forests have suffered greatest declines in the past, and further declines may ultimately lead to ecosystem collapse. My research seeks to unravel community relationship between mammals and fungi, and how interactions within and between these groups maintain diverse communities. My results will enable forest managers to protect forest biodiversity from current and future threats and to restore degraded ecosystems. Through training of early career ecologists, the research also represents a tangible benefit to Australian science.Read moreRead less
