Ecosystem Assembly in Old Fields in the Western Australian Wheatbelt. This project aims to examine the process of ecosystem re-assembly on land which is taken out of agricultural production and left without further management. Land abandonment is common in many parts of the world and could increase dramatically in Australia due to land degradation, salinity and structural change. We will investigate the factors which influence whether native plant species can recolonise abandoned farmland, usin ....Ecosystem Assembly in Old Fields in the Western Australian Wheatbelt. This project aims to examine the process of ecosystem re-assembly on land which is taken out of agricultural production and left without further management. Land abandonment is common in many parts of the world and could increase dramatically in Australia due to land degradation, salinity and structural change. We will investigate the factors which influence whether native plant species can recolonise abandoned farmland, using field and greenhouse studies. We will do this within the context of ecosystem assembly, thereby answering a practical question and also providing input to a conceptual area which is currently of great interest inRead moreRead less
Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non- ....Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non-government agencies across the entire Kimberley region. It will also result in the evaluation of methods for deployment of taste-aversion at a landscape scale. This should provide significant benefits by conserving vulnerable fauna and building a powerful network within a region of high biodiversity in tropical Australia.Read moreRead less
The role of mycorrhizal fungi in the nutrition of temperate terrestrial orchids. This project addresses the role of external mycelial systems in the carbon and mineral nutrition of temperate terrestrial orchids. The project will determine the processes of nutrient transfer in the protocorm and adult phases of development across a range of terrestrial temperate orchids to inform conservation and restoration efforts.
How does soil fertility affect jarrah forest rehabilitation after mining? This project will examine the effect of fertiliser additions on the species composition and functional diversity of jarrah forest that develops after bauxite-mining. It is directly relevant to the achievement of the sustainable use of natural resources in Australia. Expected outcomes are best-practice management guidelines regarding the amount of fertiliser that results in the most effective achievement of completion cri ....How does soil fertility affect jarrah forest rehabilitation after mining? This project will examine the effect of fertiliser additions on the species composition and functional diversity of jarrah forest that develops after bauxite-mining. It is directly relevant to the achievement of the sustainable use of natural resources in Australia. Expected outcomes are best-practice management guidelines regarding the amount of fertiliser that results in the most effective achievement of completion criteria, and also an improved understanding of the consequences of fertiliser application on the biodiversity (plants and soil biota) and ecosystem function of rehabilitated forest ecosystems.

Resilience of forest ecosystems to multiple stressors in a changing climate. This project will examine the influence of multiple stressors including disease, drought and fire, on the resilience of forest ecosystems within Australia. This project expects to generate new knowledge for land managers and the international community, in management of forest health by determining how soil health and soil fungi influence forest recovery after disturbance events. Anticipated outcomes include improved ri ....Resilience of forest ecosystems to multiple stressors in a changing climate. This project will examine the influence of multiple stressors including disease, drought and fire, on the resilience of forest ecosystems within Australia. This project expects to generate new knowledge for land managers and the international community, in management of forest health by determining how soil health and soil fungi influence forest recovery after disturbance events. Anticipated outcomes include improved risk assessment of disturbed forests to future disturbances and significant benefits will include informing climate smart management goals in the recovery of important forest ecosystems, not only for the forest tree species but the animal, plant, insect and microbe communities that depend on these systems.Read moreRead less
Ecology, impact and control of cane toads on the southern invasion front. The invasion of cane toads has killed many native animals in tropical Australia, but the toads’ southern (NSW) invasion front remains unstudied. This project will build on recent research to understand how toads affect southern biodiversity, and will develop new ways to reduce that impact.

Summary
High-throughput sample preparation robotics to enable emerging large-scale plant genomics, metabolomics and proteomics research. Discovering and breeding plants that are best suited for new environmental conditions requires the analysis of many samples to discover the underlying genes, metabolites and proteins. The project will build two robotic instruments that will facilitate the rapid grinding and extraction of plant tissues to facilitate these discoveries across Australia.
Ants, plants, diversity and function: trophic interactions and ecosystem function in a large-scale restoration experiment. Food and clean water are but two of the benefits we reap from functioning ecosystems, but we know little about how individual species contribute to making ecosystems work. This project capitalises on the diversity of Australia's ant fauna by using ants as a model taxon to explore the link between biodiversity and ecosystem functioning.
Is reintroduction of soil foraging animals critical for the restoration of degraded semi-arid woodlands? Locally-extinct animals are important, not only for their intrinsic value, but because they are thought to be essential for maintaining and restoring healthy ecosystems. This project will give us valuable insights into how ecosystems may have functioned prior to the loss of native animals, and how ecosystems can be restored when the animals are reintroduced. Our research will provide Australi ....Is reintroduction of soil foraging animals critical for the restoration of degraded semi-arid woodlands? Locally-extinct animals are important, not only for their intrinsic value, but because they are thought to be essential for maintaining and restoring healthy ecosystems. This project will give us valuable insights into how ecosystems may have functioned prior to the loss of native animals, and how ecosystems can be restored when the animals are reintroduced. Our research will provide Australian Wildlife Conservancy with the knowledge they need to continue their reintroductions, and information that encourages land managers to adopt strategies to ensure the survival of reintroduced animals outside of formal reserves.

The roles of invasive ants in urban ecosystem dynamics and restoration. The potential impacts of invasive ants are recognised worldwide, and we know that invasive ant species are already present in heavily disturbed areas in southern Australia, particularly in urban settlements. However, as yet, we have very little information on the actual and potential impacts of invasive ants on ecosystem processes. Urban bushland is seen as an important conservation and amenity resource, and there are incre ....The roles of invasive ants in urban ecosystem dynamics and restoration. The potential impacts of invasive ants are recognised worldwide, and we know that invasive ant species are already present in heavily disturbed areas in southern Australia, particularly in urban settlements. However, as yet, we have very little information on the actual and potential impacts of invasive ants on ecosystem processes. Urban bushland is seen as an important conservation and amenity resource, and there are increasing efforts to manage and restore these areas. This project aims to elucidate the likely impact of invasive ants on the maintenance and restoration of urban bushland, and hence provide guidance as to whether management and restoration needs to include invasive ant control.
