Conservation of threatened species is expensive and success rare or fleeting. Analysis of nearly three decades of threatened species conservation management, and an understanding of the complex of factors that affect success, will help increase the efficiency of conservation planning. Improved understanding of the biological, economic, social and institutional environment within which conservation management occurs will help managers allocate resources appropriately. This type of analysis has never been done for an entire fauna at a continental scale and will have global significance. Furthermore the networks to which the investigators are connected will ensure that the results can be rapidly translated into practice.Read moreRead less
Vegetation change in coastal Parks and Reserves: risk assessment and management of woody invaders. Coastal heath ecosystems contain some of the highest diversity of plant species for any vegetation type within temperate Australia. These communities exist within and outside the Reserve system, but even those within Parks and Reserves may be undergoing rapid change in structure and composition as a result of invading environmental weeds, resulting in a significant loss of biological diversity. As ....Vegetation change in coastal Parks and Reserves: risk assessment and management of woody invaders. Coastal heath ecosystems contain some of the highest diversity of plant species for any vegetation type within temperate Australia. These communities exist within and outside the Reserve system, but even those within Parks and Reserves may be undergoing rapid change in structure and composition as a result of invading environmental weeds, resulting in a significant loss of biological diversity. As agriculture, tourism and other developments place increasing pressure on these diminishing ecosystems, the maintenance of their biodiversity takes on increasing importance. This project will identify threatening processes and devise cost-effective, practicable management strategies in a context of competing stakeholder interests.Read moreRead less
Designing and Evaluating Biodiversity Conservation Policies for the Future. Biodiversity loss is a concern worldwide, especially in Australia with one of the world's 25 biodiversity "hot spots". Poor translation of ecology into policy and an absence of policy design principles are significantly impeding our ability to arrest these losses.

Biodiversity loss is a concern worldwide, especially in Australia with one of the world's 25 biodiversity "hot spots". Poor translation of ecology into policy and an absence of policy design principles are significantly impeding our ability to arrest these losses. This project aims to translate current developments in ecological theory into information useful for policy makers, develop and apply an evaluation framework to current biodiversity policies using this new information, and develop policy design principles based on this evaluation. The project's expected outcomes - a clear translation of ecological theory for policy makers, and evaluation criteria and design principles for biodiversity policies - will contribute to conserving biodiversity.

Biology and Integrated conservation of temperate Australian orchids. To successfully conserve rare and endangered orchids an integrated approach to translocation must be adopted. The orchid species and associated fungal symbionts must be succesfully established at a site to achieve a self-sustaining population. Currently little is know about the in situ interactions of orchid and fungal endophytes. Research here will determine essential field interactions and requirements of both partners.

The orchid species and associated fungal symbionts must be succesfully established at a site to achieve a self-sustaining population. Currently little is know about the in situ interactions of orchid and fungal endophytes. Research here will determine essential field interactions and requirements of both partners. The ex situ conservation of rare and endangered species should included reliable long-term storage of propagation material such as seed. Information obtained will be used to develop orchid conservation packages for implementation by landmanagers.Read moreRead less

The results from this project will be a key reference when assessing future impacts of human-induced impacts on natural communities. Our research will provide insights into the impacts of climate change on herbivorous insects associated with Acacia: the dominant plant genus in the major climatic zones of Australia. Results and conclusions from this research will aid land-holders, government agencies and other parties in determining how important Acacia-dominated ecosystems are in conserving insect biodiversity in a range of different habitats within regional and rural Australia. Our research will also aid in a better understanding of biocontrol agents of Australian Acacia pest species here and overseas.Read moreRead less
Conservation Management of the Endangered Pygmy Bluetongue Lizard. The Pygmy Bluetongue Lizard probably occurred over 150km of the Adelaide Plains before European settlement, but is now known from only a few privately owned properties in the mid-north of South Australia. Before adopting specific conservation strategies, such as release to new sites, more needs to be known about the genetic and social structure of viable populations, and the natural parasite fauna that may detrimentally affect an ....Conservation Management of the Endangered Pygmy Bluetongue Lizard. The Pygmy Bluetongue Lizard probably occurred over 150km of the Adelaide Plains before European settlement, but is now known from only a few privately owned properties in the mid-north of South Australia. Before adopting specific conservation strategies, such as release to new sites, more needs to be known about the genetic and social structure of viable populations, and the natural parasite fauna that may detrimentally affect any transplants. This project explores those aspects of the lizard biology, enhancing both our general understanding of lizard population structure and our specific understanding of conservation issues for this species.Read moreRead less
Extrinsic threats and biological predisposition in animal extinction and rediscovery. A global extinction crisis looms, and Australia has a shocking record, especially of mammal extinctions. The results of this project to find how different threats affect each species will lead to management that focusses on species- and region-specific causes. This will help to prevent further extinctions of Australian mammals and other fauna. Many people hope that species of particular importance to us such as ....Extrinsic threats and biological predisposition in animal extinction and rediscovery. A global extinction crisis looms, and Australia has a shocking record, especially of mammal extinctions. The results of this project to find how different threats affect each species will lead to management that focusses on species- and region-specific causes. This will help to prevent further extinctions of Australian mammals and other fauna. Many people hope that species of particular importance to us such as the thylacine have defied extinction, and will be rediscovered. This project will test which predictive factors can increase the chance of species rediscovery, and help management agencies plan for the expected number of future rediscoveries.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
Understanding and managing resistance to the amphibian chytrid fungus Batrachochytrium dendrobatidis in Australian tropical rainforest frogs. The fungal disease chytridiomycosis can infect at least 48 Australian native frog species and is listed as a threatening process under the federal Environment Protection and Biodiversity Conservation Act. It caused catastrophic declines in 12 frog species in Queensland between 1979 and 1994, and is probably responsible for continuing declines in many more ....Understanding and managing resistance to the amphibian chytrid fungus Batrachochytrium dendrobatidis in Australian tropical rainforest frogs. The fungal disease chytridiomycosis can infect at least 48 Australian native frog species and is listed as a threatening process under the federal Environment Protection and Biodiversity Conservation Act. It caused catastrophic declines in 12 frog species in Queensland between 1979 and 1994, and is probably responsible for continuing declines in many more species in most states. A few species and populations have recovered following declines, indicating that they have increased their resistance to the disease. Understanding these increases in resistance should allow us to develop ways to control the disease in other species, helping to protect Australia against this invasive and highly destructive disease.Read moreRead less
