Restoring resilience in wildlife populations. This project will be the first to develop landscape models of habitat quality for wildlife that are based on a mechanistic, animal-centric approach to quantifying habitat. This will be an important step in understanding the habitat elements that wildlife need to live in altered landscapes, with implications central to restoration and revegetation.
Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional en ....Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional endemism or key roles in dispersal of larvae. The ecological efficacy of the temperate Australian MPA network will be assessed through analysis of long-term ecological datasets and further development of a novel 'remote sensing' methodology, whereby surveys are undertaken by volunteer divers across much greater spatial and temporal scales than could be studied by dedicated scientific dive teams.Read moreRead less
Developing Assisted Reproductive Technologies for the Conservation of Critically Endangered Australian Amphibians. Unprecedented rates of species extinction are of global concern. Although high extinction rates are reported for all vertebrate classes, amphibians are the most severely affected. Captive-breeding programs play a key role in maintaining populations of endangered amphibian species, but in most cases reproductive rates are too low to support long term re-introduction programmes. This ....Developing Assisted Reproductive Technologies for the Conservation of Critically Endangered Australian Amphibians. Unprecedented rates of species extinction are of global concern. Although high extinction rates are reported for all vertebrate classes, amphibians are the most severely affected. Captive-breeding programs play a key role in maintaining populations of endangered amphibian species, but in most cases reproductive rates are too low to support long term re-introduction programmes. This study aims to develop sophisticated Assisted Reproductive Technologies (ART) to enhance the propagation and genetic management of endangered Australian frog species. ART is a powerful new approach to ex situ conservation that, if integrated into existing captive breeding programs, will ensure the preservation of Australia’s unique amphibian biodiversity.Read moreRead less
Genetic rescue of Australian wildlife. Genetic rescue of Australian wildlife. This project aims to test genetic rescue as an efficient recovery technique for threatened plants and animals. Genetic rescue is under-utilised, even though it is overwhelmingly beneficial. This project will convert management actions on five Endangered/Critically Endangered species into rigorous experiments that measure the fitness benefits of genetic rescue, and demonstrate genome-wide consequences. Anticipated outco ....Genetic rescue of Australian wildlife. Genetic rescue of Australian wildlife. This project aims to test genetic rescue as an efficient recovery technique for threatened plants and animals. Genetic rescue is under-utilised, even though it is overwhelmingly beneficial. This project will convert management actions on five Endangered/Critically Endangered species into rigorous experiments that measure the fitness benefits of genetic rescue, and demonstrate genome-wide consequences. Anticipated outcomes include innovative genetic rescue protocols, a framework for genetic rescue, and leading-edge conservation training. Expected benefits are increased persistence of species that are otherwise unresponsive to management, and a new path to saving endangered species.Read moreRead less
Onsets not offsets for real biodiversity gains. This project addresses the profound challenge of reconciling development and biodiversity conservation by developing an alternative to the pervasive, yet unsuccessful, biodiversity offsetting approach. It will generate new knowledge in the areas of novel ecosystem function, land use optimisation and conservation attitudes. Key project outcomes will be a new framework for biodiversity onsetting, tested against environmental and social feasibility me ....Onsets not offsets for real biodiversity gains. This project addresses the profound challenge of reconciling development and biodiversity conservation by developing an alternative to the pervasive, yet unsuccessful, biodiversity offsetting approach. It will generate new knowledge in the areas of novel ecosystem function, land use optimisation and conservation attitudes. Key project outcomes will be a new framework for biodiversity onsetting, tested against environmental and social feasibility metrics, and new biodiversity evaluation methods for novel habitats. The project will provide environmental and economic benefits by reversing the ongoing decline in biodiversity from habitat loss and driving innovation in environmentally destructive industries that are vulnerable to climate change.Read moreRead less
Arresting declines of arboreal mammals in the tropical savannas. This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western A ....Arresting declines of arboreal mammals in the tropical savannas. This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western Australian Department of Parks and Wildlife in the Kimberley, the last region on the Australian mainland with an intact mammal fauna, the project aims to explore management options for increasing the availability of hollow denning sites for arboreal mammals (e.g. fire management, artificial nest boxes), and evaluate the likely impact of such actions on mammal populations across northern Australia.Read moreRead less
Pyroherbivory and the nexus between Aboriginal fire mosaics and kangaroos. This project aims to examine the effects of traditional Aboriginal and contemporary fire management on kangaroo abundance. There is concern that the cessation of Aboriginal patch burning is causing savanna kangaroo populations to decline across northern Australia. In this project, surveys will be planned to determine whether fire regime (frequency, extent, season) affects kangaroo distribution and abundance and the degree ....Pyroherbivory and the nexus between Aboriginal fire mosaics and kangaroos. This project aims to examine the effects of traditional Aboriginal and contemporary fire management on kangaroo abundance. There is concern that the cessation of Aboriginal patch burning is causing savanna kangaroo populations to decline across northern Australia. In this project, surveys will be planned to determine whether fire regime (frequency, extent, season) affects kangaroo distribution and abundance and the degree to which non-native large herbivores compete with kangaroos for forage. Experiments will also be planned to discover how the season of burning influences forage quality and quantity. This project is designed to determine if patch burning can be used for ecological restoration in areas where this type of fire management has ceased and for improvement of tropical savanna fire management.Read moreRead less
Genetic rescue, restoration and adaptation. This project aims to evaluate a promising but rarely used method of population recovery by genetically rescuing populations of two threatened Australian mammals: the mountain pygmy possum and the eastern barred bandicoot. Despite our best efforts to curb biodiversity loss, extinction rates are increasing and Australia is expected to lose a substantial proportion of its unique endemic fauna over the next 20–50 years. By tracking the phenotypic and under ....Genetic rescue, restoration and adaptation. This project aims to evaluate a promising but rarely used method of population recovery by genetically rescuing populations of two threatened Australian mammals: the mountain pygmy possum and the eastern barred bandicoot. Despite our best efforts to curb biodiversity loss, extinction rates are increasing and Australia is expected to lose a substantial proportion of its unique endemic fauna over the next 20–50 years. By tracking the phenotypic and underlying genomic changes that occur when a population undergoes a genetic rescue, the project aims to create data of interest to conservation biology.Read moreRead less
An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host ....An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host and symbiont response to changing water temperature along a latitudinal gradient. The intended outcome of the project is to provide knowledge to support predictions of likely species migrations from tropical to subtropical waters, enabling managers to anticipate the future response of coral communities to seawater warming.Read moreRead less
Using pollinators to optimise plant conservation translocation. This project aims to address the low success rate of conservation translocations of threatened orchids. While pollinators are critical for plant reproduction, they are very rarely considered when establishing new populations of endangered species.

This project aims to address the low success rate of conservation translocations of threatened orchids. While pollinators are critical for plant reproduction, they are very rarely considered when establishing new populations of endangered species. Our innovative approach to conservation translocation involves using pollinators in site selection, developing strategies to mitigate risks of hybridisation, and optimising plant reproduction through planting design. The key outcome will be best-practice protocols to fast-track the establishment of self-sustaining populations. Due to their novelty, the approaches we develop will benefit plant translocations worldwide, and lead to enhanced conservation outcomes at reduced financial cost. Read moreRead less
