A systems model for taming a wicked environmental problem. Demand for beef is increasing dramatically, particularly in Asia. This project aims to build systems models of local environmental impacts of beef production coupled with models of global beef trade to analyse production and policy scenarios. Beef is the food commodity with the largest ecological footprint, and increased production will have globally significant impacts on land and water resources, biodiversity, and climate. The scale of these impacts depends on where and how cattle production occurs. Outcomes of this research include a framework for projecting regional and global ecological impacts of domestic cattle production policies, allowing informed decisions that consider and benefit environmental and socio-economic values.Read moreRead less
The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interacti ....The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interactions and an ability to quantify the biomass, social structure, and behaviours of predators required to influence these processes. Benefits should include improvements in how the ecological role of large carnivores is measured, and when and where carnivore populations should be culled or conserved.Read moreRead less
Conservation of tropical forests for their carbon and biodiversity values. International efforts to save tropical forests for the carbon they store could help mitigate climate change and biodiversity loss. This project will aid these efforts by developing methods to model future deforestation and extending decision theory for the new challenges presented by international carbon-payment schemes.
Operationalizing marine reserve design for rebuilding tropical fisheries. Operationalizing marine reserve design for rebuilding tropical fisheries. This project intends to maximise the scope for rebuilding reef fisheries while ensuring short-term levels do not become too low.

This project intends to maximise the scope for rebuilding reef fisheries while ensuring short-term levels do not become too low. Like many developing countries, Indonesia wishes to rebuild its heavily over-exploited coral reef fisheries. Marine reserves allow fish populations to recover and replenish fished areas. However, because reserves remove fishing grounds, fish catches tend to decrease in the short-term while fish recover in reserves; a process that can take a decade. Loss of yield can be so burdensome that managers abandon fisheries. This research is intended to improve the economic security of fishers and food security, and inform World Bank and Australian aid programs.Read moreRead less
Tipping points and early warning signals in complex ecosystems. This project aims to create a theory of early warning that uses spatial data available on system state, connectivity and environmental stress, and to create tools to infer the risk of ecosystem collapse. Many ecosystems have irreversible tipping points. Since their locations are often unknown, metrics may provide an early warning of collapse but are difficult to apply because they need long time series which are usually lacking. Thi ....Tipping points and early warning signals in complex ecosystems. This project aims to create a theory of early warning that uses spatial data available on system state, connectivity and environmental stress, and to create tools to infer the risk of ecosystem collapse. Many ecosystems have irreversible tipping points. Since their locations are often unknown, metrics may provide an early warning of collapse but are difficult to apply because they need long time series which are usually lacking. This project will use the Great Barrier Reef as a testbed because it has both long time series (standard approach) and rich spatial data (new approach), and exhibits early warning signs. We will use these tools to gauge whether symptoms on the Great Barrier Reef predict local collapse and to develop intervention plans.Read moreRead less
Biodiversity indicators for better conservation decisions. This project aims to test, design and select biodiversity indicators to support conservation. Reliable and sensitive biodiversity indicators are critical to track progress towards conservation targets, but the ability of most biodiversity indicators to reveal trends needed by decision-makers is untested. This project will test indicators to monitor biodiversity change at local to global scales, by sampling ecosystem models to evaluate ho ....Biodiversity indicators for better conservation decisions. This project aims to test, design and select biodiversity indicators to support conservation. Reliable and sensitive biodiversity indicators are critical to track progress towards conservation targets, but the ability of most biodiversity indicators to reveal trends needed by decision-makers is untested. This project will test indicators to monitor biodiversity change at local to global scales, by sampling ecosystem models to evaluate how indicator design, data bias and environmental variability affect performance. Project outcomes are expected to ensure that that data collected to monitor and assess the state of Australia’s environment are informative, cost-effective and robust. This is expected to have implications for predicting and measuring effects of policy such as the Convention on Biological Diversity.Read moreRead less

Understanding the ecological and economic implications of reef fish larval dispersal. Until we understand larval dispersal, the movement of reef fish during their juvenile stage, we cannot sustainably manage coral reef ecosystems. This project will use sophisticated mathematical tools to understand how larval dispersal influences the ecology and management of the Great Barrier Reef and a fishery in Papua New Guinea.
Marine conservation planning for persistent coral reef communities: Incorporating connectivity and resilience. Australia's biological diversity underpins much of our economic wealth - for example the remarkable diversity of coral reefs fuels a multibillion dollar tourism industry. However, despite substantial efforts to conserve marine ecosystems, Australian coral reefs are at increasing risk from climate change related catastrophes. To counteract this trend, we must choose marine reserve networ ....Marine conservation planning for persistent coral reef communities: Incorporating connectivity and resilience. Australia's biological diversity underpins much of our economic wealth - for example the remarkable diversity of coral reefs fuels a multibillion dollar tourism industry. However, despite substantial efforts to conserve marine ecosystems, Australian coral reefs are at increasing risk from climate change related catastrophes. To counteract this trend, we must choose marine reserve networks using methods that account for the dynamic nature of climate change and reef community responses to maximise the persistence of reef biodiversity. The new theory and methods will enable us to create more effective and economically efficient marine reserve systems.Read moreRead less

This project seeks to investigate the conditions under which policies that prohibit or regulate trade in wildlife products are more likely to lead to conservation outcomes. Illegal trade in wildlife is a pressing conservation issue, threatening numerous species with extinction. The crisis has attracted over US$350 million in donor and government funding since 2012, primarily for enforcement of trade bans. Fierce debates rage in the academic literature about the conditions under which regulated markets may yield better outcomes. Policy options are also constrained by opinions about whether pro-use policies for wildlife are morally appropriate. The project aims to investigate this issue and assess the impact of stakeholder values and preferences on policy decisions.Read moreRead less
