This project aims to develop innovative laser cleaning processes to conserve the structural integrity and iconic status of the Sydney Harbour Bridge. New laser technologies offer the opportunity to remove lead-based paint and clean the bridge’s metal structures and granite pylons offering advantages unavailable with current techniques. The expected outcomes will be new best-practice laser conservation techniques usable for both hand-held and automated systems to preserve one of the most iconic bridges in the world. This will reduce maintenance frequency and cost, restore the beauty of the bridge, retain its engineering significance and provide a baseline process for cleaning of other historical large scale metal and stone heritage objects.Read moreRead less
Snails to the rescue! Conservation of Australia’s island invertebrates. This project aims to deliver an exemplar industry network model for conservation on Australia’s islands which are hotspots both of biodiversity and of extinctions. Protecting species on islands is therefore key to securing Australia’s biodiversity.

This project aims to deliver an exemplar industry network model for conservation on Australia’s islands which are hotspots both of biodiversity and of extinctions. Protecting species on islands is therefore key to securing Australia’s biodiversity. We will secure Norfolk Island's 60 species of land snails via in situ and ex situ conservation with six key industry partners. The project expects to unite conservation actions across research, governments, and industry. Expected outcomes of this project include Norfolk Island emerging as a leader in global conservation. This should provide significant benefits such as a model for conservation that is applicable to thousands of isolated, range-restricted invertebrate species across Australia.Read moreRead less
Plant diversity in restored native vegetation of agricultural landscapes. This project will assess the success of current practices of native vegetation restoration in agricultural regions, ie whether they provide sustainable habitat for native plant species. While there is currently a massive expenditure on revegetation in agriculture, there has been almost no assessment of whether it works well or not. This study will compare the plant species present in restored and comparable native vegeta ....Plant diversity in restored native vegetation of agricultural landscapes. This project will assess the success of current practices of native vegetation restoration in agricultural regions, ie whether they provide sustainable habitat for native plant species. While there is currently a massive expenditure on revegetation in agriculture, there has been almost no assessment of whether it works well or not. This study will compare the plant species present in restored and comparable native vegetation. Additionally, intensive study of some key plant species will be undertaken to determine what features of these plants enable them to persist in restored patches. Outcomes include new assessment techniques and original data.Read moreRead less
Restoration of temperate eucalypt woodland: getting it right. Eucalypt woodlands of southern Australia have been heavily cleared for agriculture: much effort and expense is going towards revegetation of these woodlands to conserve biodiversity, and restore ecosystem services they provide. Current restoration methods are purely empirical, with little understanding of why they work. This project will experimentally investigate revegetation practices to uncover ecological processes they utilise, an ....Restoration of temperate eucalypt woodland: getting it right. Eucalypt woodlands of southern Australia have been heavily cleared for agriculture: much effort and expense is going towards revegetation of these woodlands to conserve biodiversity, and restore ecosystem services they provide. Current restoration methods are purely empirical, with little understanding of why they work. This project will experimentally investigate revegetation practices to uncover ecological processes they utilise, and other ecological processes that potentially can be utilised but are currently not. The cost-effectiveness of different practices will be compared. The outcome of the project will be revegetation practices for eucalypt woodlands that are evidence-based and cost-effective, rather than rule of thumb.Read moreRead less
Fire severity, habitat heterogeneity and life histories. Resolving the persistence ability of plants in frequently fired landscapes. The wise management of Australia's biodiversity has major economic and social benefits for the nation through the provision of ecosystem services, bio-products and tourism. Fire is a pivotal environmental factor that will continue to influence plant biodiversity in fire-prone ecosystems. Inappropriate fire regimes, however, threaten biodiversity through disruption ....Fire severity, habitat heterogeneity and life histories. Resolving the persistence ability of plants in frequently fired landscapes. The wise management of Australia's biodiversity has major economic and social benefits for the nation through the provision of ecosystem services, bio-products and tourism. Fire is a pivotal environmental factor that will continue to influence plant biodiversity in fire-prone ecosystems. Inappropriate fire regimes, however, threaten biodiversity through disruption of life cycles. If too many or too few fires occur in an area this can lead to decline and extinction of plant and animal species. This research will provide a risk-assessment tool for the management of biodiversity to reverse population declines and prevent extinctions.

Experimental translocations to understand and combat eastern quoll declines. The project aims to understand the causes of observed declines of the eastern quoll in Tasmania, and develop tools to safeguard this species in their last wild stronghold. The project will test the innovative approach of undertaking a series of experimental translocations at an early stage of a population decline. This approach will provide reliable information on the causes of observed declines, while simultaneously te ....Experimental translocations to understand and combat eastern quoll declines. The project aims to understand the causes of observed declines of the eastern quoll in Tasmania, and develop tools to safeguard this species in their last wild stronghold. The project will test the innovative approach of undertaking a series of experimental translocations at an early stage of a population decline. This approach will provide reliable information on the causes of observed declines, while simultaneously testing the effectiveness of translocations of captive-bred animals as a management tool for the species. It will also develop evidence-based protocols for undertaking captive-bred translocations, to improve the outcomes of eastern quoll recovery efforts as well as promoting early intervention for other declining species.

This project is a test-case for a new integrated proactive management of invading pest species. The partner industries are responsible for controlling European starling invasions that threaten agriculture and Australia's only internationally-recognised terrestrial biodiversity hotspot. This project combines traditional ecology, novel molecular approaches, and new statistics to establish source population(s), and disperser characteristics. This will enable a focused control effort, and training of a graduate student and partner industries in this approach. This project is of great significance to rural Australia, and falls within several research priority areas: protection from pests (RP4, PG2) and an environmentally sustainable Australia (RP1, PG2,3).Read moreRead less
