The project will help to predict changes in biodiversity from different development options, and will identify forms of urban design that provide improved biodiversity outcomes. The case study region (SE Queensland) is a national "biodiversity hotspot" due to high biodiversity combined with high threat from urbanisation. Findings will also be relevant to the ecological sustainability of forest ecosystems and urban areas throughout Australia. The project will develop decision-support tools for conservation planning, with the involvement of research partners from local government and regional environmental management. This will contribute to the sustainable use of Australia's biodiversity, a national research priority.Read moreRead less
Reimagining the Australian Suburb: Biodiversity planning in urban fringe landscapes. Over 40% of nationally listed threatened ecological communities occur in urban areas. Accelerating urbanisation in Australia is considered one of the greatest threats to biodiversity. This threat will increase without a more strategic approach to conservation planning in urban environments. Protection of biodiversity in urban areas brings numerous societal benefits but involves complicated tradeoffs between com ....Reimagining the Australian Suburb: Biodiversity planning in urban fringe landscapes. Over 40% of nationally listed threatened ecological communities occur in urban areas. Accelerating urbanisation in Australia is considered one of the greatest threats to biodiversity. This threat will increase without a more strategic approach to conservation planning in urban environments. Protection of biodiversity in urban areas brings numerous societal benefits but involves complicated tradeoffs between competing land uses including housing development, agricultural production and conservation. This project builds on recent advancements in ecological modelling and mathematical optimisation to develop and test tools to facilitate transparent decisions based on optimal trade-offs between competing values. It will result in a more strategic approach to planning conservation in urban environments.Read moreRead less
Practical, powerful and cost effective indicators of sustainable forest management for the conservation of biological diversity. Much debate about appropriate use of Australia's forests stems from uncertainty about the magnitude of impacts on abundances and distributions of forest-dependent species, a key indicator of sustainable management under the Montreal Process. An opportunity exists to develop new tools to substantially improve our ability to detect and assess change. This project will de ....Practical, powerful and cost effective indicators of sustainable forest management for the conservation of biological diversity. Much debate about appropriate use of Australia's forests stems from uncertainty about the magnitude of impacts on abundances and distributions of forest-dependent species, a key indicator of sustainable management under the Montreal Process. An opportunity exists to develop new tools to substantially improve our ability to detect and assess change. This project will develop optimal monitoring design and analysis strategies for detecting population trends against a background of natural fluctuation and observation error. It will result in templates for coherent reporting on indicators at regional and national levels. It will exploit recent findings regarding observation error in surveys, advances in statistical control processes, simulation methods, and power analysis to develop a world-class species monitoring system.Read moreRead less
Watching migrating whales: ensuring the sustainability of a growing whale-watch industry. Whale-watching is a huge growth industry, contributing $270 million to Australia in 2003. Yet most whalewatching targets species listed under the EPBC Act 1999 as species slowly recovering from massive overexploitation. Current protection measures are historical (ie best-guess) rather than scientific in origin. We will assess the scientific basis for these protection measures by experimentally manipulating ....Watching migrating whales: ensuring the sustainability of a growing whale-watch industry. Whale-watching is a huge growth industry, contributing $270 million to Australia in 2003. Yet most whalewatching targets species listed under the EPBC Act 1999 as species slowly recovering from massive overexploitation. Current protection measures are historical (ie best-guess) rather than scientific in origin. We will assess the scientific basis for these protection measures by experimentally manipulating tour boat behaviour, and by determining the economic feasibility of the industry. By doing so we will increase the long-term sustainability of the industry, a valuable tourist industry for regional Australia.Read moreRead less
Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia ....Modelling and control of mosquito-borne diseases in Darwin using long-term monitoring. Management of mosquito populations is a high public health priority because these insects can spread diseases such as malaria, dengue, Ross River virus, Barmah Forest virus, Murray Valley encephalitis, Japanese encephalitis and Kunjin/West Nile virus. Our research into the effectiveness of mosquito control programs in Darwin is of immediate national relevance and priority given the need to Safeguard Australia from invasive diseases. There is an urgency to undertake our research because global environmental change and increasing movements of people (particularly military personnel) from overseas regions where these diseases are endemic is increasing the vulnerability of northern Australia to the (re)establishment of mosquito borne diseases.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

Assisted breeding technology will provide a new paradigm for solving problems associated with the preservation and management of captive and wild Koala populations. This project aims to improve methods of koala sperm cryopreservation and its subsequent use in artificial insemination and to establish a functional frozen sperm bank screened for the most prevalent pathogens. Important outcomes will include (1) a reliable, cost effective and disease free approach to the transfer of Koala genetic material into international and national zoos; (2) a technique for the management of free-range genetically restricted Koala populations and (3) successful cryostorage of Koala spermatozoa for the long-term maintenance of genetic potential.Read moreRead less
Enhancement of fish stock by habitat manipulation in artificial coastal waterways. Human settlement significantly changes the spatial characteristics of natural coastal waterways. The value of artificial waterways, such as canals, as a habitat for fish is poorly known. We will evaluate the significance of artificial canals as a fish habitat, and test the effect of habitat modification by artificial reef installation on fish distribution and abundance. We will investigate whether artificial reefs ....Enhancement of fish stock by habitat manipulation in artificial coastal waterways. Human settlement significantly changes the spatial characteristics of natural coastal waterways. The value of artificial waterways, such as canals, as a habitat for fish is poorly known. We will evaluate the significance of artificial canals as a fish habitat, and test the effect of habitat modification by artificial reef installation on fish distribution and abundance. We will investigate whether artificial reefs enhance fish production in canals, rather than simply acting as fish aggregation devices. This research will address an important question in fisheries ecology and help formulate management guidelines for artificial waterways.Read moreRead less
Assessing linkages across arid zone estuarine landscapes. We aim to understand the degree of connectivity between the terrestrial environment and estuaries in the arid tropics of Australia. We will investigate the impact of terrestrial-estuarine linkages on near shore food webs, which include a diverse fauna, some of which are commercially important. Human activities in the land-ocean interface have to have the capacity to alter greatly the timing, magnitude, and composition of inputs from water ....Assessing linkages across arid zone estuarine landscapes. We aim to understand the degree of connectivity between the terrestrial environment and estuaries in the arid tropics of Australia. We will investigate the impact of terrestrial-estuarine linkages on near shore food webs, which include a diverse fauna, some of which are commercially important. Human activities in the land-ocean interface have to have the capacity to alter greatly the timing, magnitude, and composition of inputs from watersheds to estuaries, thereby greatly altering the function of estuaries. The results of this project will fill a gap in our knowledge of how arid zone estuaries function, and will contribute to developing management strategies needed to maintain estuary productivity.Read moreRead less
Conservation management of seed-eating birds in the tropical savannas. Biodiversity loss in the savannas indicates unsustainable management.

Biodiversity loss in the savannas indicates unsustainable management. This research will enhance our abilities to effectively manage Australia's tropical savannas, as well as contributing to several State and Territory, Commonwealth and international obligations to maintain biodiversity. Understanding the processes underlying current declines will also make the effects of future management or environment changes easier to predict. Retaining threatened species can benefit remote and regional communities through tourism, and also through the extra employment required to implement the management prescriptions that will be developed from this research.Read moreRead less
