This project will provide tools essential for the effective management of Australia's ecosystems by delivering clear guidelines and practical methods that will substantially improve the modelling of future species distributions.
Economics of Conserving Australian Tropical Wildlife: An Analysis of the Role of Economic Valuation, Property Rights and Commercialisation. Australian tropical native animals are selected to analyse economic valuation (use and non-use valuation) of wildlife species and to assess systematically the role of property rights and commercialisation in conservation. The project will (1) reduce bias of Australian economic studies in favour of temperate species; (2) answer several unresolved questions ra ....Economics of Conserving Australian Tropical Wildlife: An Analysis of the Role of Economic Valuation, Property Rights and Commercialisation. Australian tropical native animals are selected to analyse economic valuation (use and non-use valuation) of wildlife species and to assess systematically the role of property rights and commercialisation in conservation. The project will (1) reduce bias of Australian economic studies in favour of temperate species; (2) answer several unresolved questions raised in the Parlimentary Report on Commercial Utilisation of Australian Wildlife; (3) advance economic theory (e.g. relating to dynamic influences on economic valuation) and provide new insights into property rights making use of empirical and experimental results, and (4) thereby contribute to public policy decision-making.Read moreRead less
Population Viability Analysis of the Perth Metropolitan Population of the Little Penguin. The population of Little Penguins, breeding on Penguin and Garden Islands, in the Perth Metropolitan region, are an iconic species and a valuable ecotourism resource They breed and feed in close proximity to high human activity and a rapidly growing urban population. The nearest other major populations are located 600km to the south. The key benefit of this project is that it will provide a basis for meas ....Population Viability Analysis of the Perth Metropolitan Population of the Little Penguin. The population of Little Penguins, breeding on Penguin and Garden Islands, in the Perth Metropolitan region, are an iconic species and a valuable ecotourism resource They breed and feed in close proximity to high human activity and a rapidly growing urban population. The nearest other major populations are located 600km to the south. The key benefit of this project is that it will provide a basis for measuring the impacts of threats to this isolated population, and for testing management strategies. Thus it represents a key step in securing the long term future of the penguin population in Perth's waters.

Optimal management of threatened amphibian metapopulations in urbanising landscapes. This project will enable the identification of optimal management strategies for many species threatened by the loss and fragmentation of their habitat, both in Australia and internationally. Our research will contribute to the recovery of the endangered Growling Grass Frog, and drive the conservation of wetland biodiversity on the fringe of Australia's fastest growing city. Both the methods and specific recomme ....Optimal management of threatened amphibian metapopulations in urbanising landscapes. This project will enable the identification of optimal management strategies for many species threatened by the loss and fragmentation of their habitat, both in Australia and internationally. Our research will contribute to the recovery of the endangered Growling Grass Frog, and drive the conservation of wetland biodiversity on the fringe of Australia's fastest growing city. Both the methods and specific recommendations for management that we develop will contribute to the goal of an environmentally-sustainable Australia. This project will expand Australia's capacity to solve conservation problems, and will promote biological diversity in urban environments, to the benefit of their human inhabitants.Read moreRead less
General theory for eradicating multiple invasive species from threatened island ecosystems. Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive ....General theory for eradicating multiple invasive species from threatened island ecosystems. Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive species can destabilise the complex island ecosystems, further endangering the native species. The results of this project will help conservation managers to plan eradication strategies that cost-effectively eradicate populations of two introduced species, without threatening native wildlife.Read moreRead less

This project in south-western Australia develops an integrated framework to interpret knowledge about landscape processes and future trajectories of species and assemblages at different spatio-temporal scales. A synthesis of data obtained through repeated biological surveys and remote sensing, with spatial data handled through GIS is used in an explanatory modeling approach to make predictions under different disturbance regimes. Models built from combined spatial layers exhibiting continuous variation in environmental variables will provide area-class maps at different scales, allowing the portrayal of uncertainty associated with vegetation units - a considerable innovation over maps depicting homogenous discrete zones.Read moreRead less
Optimal management of complex ecological systems. Natural systems are inherently complex and difficult to predict. This complexity means that efficient management strategies are often uncertain, and resource managers have few theories or rules on which to base their decisions. We will integrate the existing theories and principles of conservation biology with decision-making tools and theory used in statistics, economics, control theory, engineering and mathematics. We will use novel methods to ....Optimal management of complex ecological systems. Natural systems are inherently complex and difficult to predict. This complexity means that efficient management strategies are often uncertain, and resource managers have few theories or rules on which to base their decisions. We will integrate the existing theories and principles of conservation biology with decision-making tools and theory used in statistics, economics, control theory, engineering and mathematics. We will use novel methods to investigate the reliability of different management decisions that are made in the face of uncertainty and involve learning. Our aim is to discover a general theory for a new branch of conservation biology: applied theoretical conservation ecology.Read moreRead less
Robust prediction and decision strategies for managing extinction risks under climate change. Climate change is a principal threat to biodiversity and ecosystem health. The loss of ecosystem services from loss of species and ecosystem change may have serious social and economic repercussions. Unreliable predictions of climate change impacts and inefficient adaptation decisions result in wasted public resources and unnecessary loss of natural assets. In addition to direct benefits of efficient ad ....Robust prediction and decision strategies for managing extinction risks under climate change. Climate change is a principal threat to biodiversity and ecosystem health. The loss of ecosystem services from loss of species and ecosystem change may have serious social and economic repercussions. Unreliable predictions of climate change impacts and inefficient adaptation decisions result in wasted public resources and unnecessary loss of natural assets. In addition to direct benefits of efficient adaptation strategies for case-study ecosystems, techniques arising from this research will improve the way we respond to uncertain, but potentially catastrophic consequences of climate change. Bringing state-of-the-art modelling and formal decision methods to climate change adaptation is a central aim of this research.Read moreRead less
The role of learning in conservation management: developing adaptive approaches for the conservation of biodiversity in a changing climate. Biodiversity underpins several major industries: agriculture, tourism, forestry and fisheries. To mitigate the loss of biodiversity, there have been significant investments from all levels of government, including 2.2 billion dollars to manage biodiversity and 138 million dollars simply to gather data on the impact of climatic changes. Despite this well inte ....The role of learning in conservation management: developing adaptive approaches for the conservation of biodiversity in a changing climate. Biodiversity underpins several major industries: agriculture, tourism, forestry and fisheries. To mitigate the loss of biodiversity, there have been significant investments from all levels of government, including 2.2 billion dollars to manage biodiversity and 138 million dollars simply to gather data on the impact of climatic changes. Despite this well intended funding, the key questions of how to best allocate this money between the many threatened species and regions of Australia, and how to adapt this allocation in light of climatic changes, remain unanswered. Our research will develop explicit and practical frameworks by which we can cost efficiently learn and act simultaneously.Read moreRead less
