Quantifying and mitigating the barrier effect of roads on the movement and dispersal of wildlife. In fragmented landscapes, wildlife need to move between habitat patches to exchange genes, increase the size of declining populations and recolonise areas were animals have become extinct. For many species, roads may act as barriers that prevent or limit dispersal, potentially isolating some habitats. In this study, we aim to quantify the extent to which major highways in regional Australia form a ....Quantifying and mitigating the barrier effect of roads on the movement and dispersal of wildlife. In fragmented landscapes, wildlife need to move between habitat patches to exchange genes, increase the size of declining populations and recolonise areas were animals have become extinct. For many species, roads may act as barriers that prevent or limit dispersal, potentially isolating some habitats. In this study, we aim to quantify the extent to which major highways in regional Australia form a barrier to the movement of mammals and invertebrates. We will then test the effectiveness of measures that may facilitate safe crossing by measuring their rate of use, reduction in road kill and increase in population viability. This information can then be used to construct major roads that are more environmentally sustainable.Read moreRead less
Integrating climate adaptation into rainforest restoration plantings. This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling gr ....Integrating climate adaptation into rainforest restoration plantings. This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling growth and survival. The expected outcome is to provide practical advice to restoration practitioners about the importance of matching the provenance of seed source to planting sites, and opportunities for selecting provenances pre-adapted to predicted future climatic conditions at planting sites.Read moreRead less
Modelling policy interventions to protect Australia's food security in the face of environmental sustainability challenges . This project will use an innovative scenario modelling approach to quantify the potential impacts of population growth and emerging climate and environmental challenges on Australia’s future food security. In collaboration with an advisory committee it will specify and prioritise policy solutions in terms of their social and economic credentials.
The Norfolk Island Carbon and Health Evaluation Program: a case study of personal carbon trading for reducing obesity and greenhouse gas emissions. This project tests a system of Personal Carbon Trading for reducing greenhouse gas emissions and improving health. Carbon credit cards given to everyone on Norfolk Island are designed to financially reward people for reducing energy use (fuel and fatty food mainly) by increasing walking/cycling and improving nutrition to improve health
More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the ....More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the relationship between tree cover, carbon uptake, water yield and biodiversity. The outcomes will allow government agencies, landowners and carbon farming groups to better evaluate the effects of different landscape planning options and contribute to effective long-term planning for multiple goals.Read moreRead less
Devising ecologically sustainable restoration programs for degraded rural landscapes by integrating landscape ecology, genetics and ecophysiology. Concern about tree decline in rural landscape is widespread, and disturbingly climate change is predicted to exacerbate this problem. Past ill-considered tree plantings have proven to be economically wasteful, achieved limited ecological resilience and negligible improvement of biodiversity values. Using Tasmania as a 'model system', we will advance t ....Devising ecologically sustainable restoration programs for degraded rural landscapes by integrating landscape ecology, genetics and ecophysiology. Concern about tree decline in rural landscape is widespread, and disturbingly climate change is predicted to exacerbate this problem. Past ill-considered tree plantings have proven to be economically wasteful, achieved limited ecological resilience and negligible improvement of biodiversity values. Using Tasmania as a 'model system', we will advance this problem by undertaking research to determine how seedling establishment, tree growth, carbon storage and water use are influenced by landscape setting, management history, climate change, species type and local varieties. This research will provide a much needed evidence to devise ecologically sustainable tree-plantings in southern Australia.Read moreRead less

The aim of this project is to develop and test a new approach for assessing the conservation value of agricultural landscapes in Australia. It is based on identifying the functional responses of the fauna to the extent and pattern of native vegetation and types and intensity of agricultural land-uses in whole landscapes. Different response types will be interpreted in relation to ecological characteristics of species. We will use this knowledge to predict the status of birds and mammals in novel landscapes in three bioregions, and test the predictions by field studies. This new landscape-level approach will help land managers assess present agricultural environments as well as evaluate scenarios for future changes in land-use.Read moreRead less

Maintenance of biodiversity is fundamental to ecologically sustainable development. This project will deepen our understanding of the consequences of landscape change for native birds and enhance our national capacity to integrate nature conservation and agricultural production. We will contribute to sustainable use of rural landscapes by providing land managers with greater understanding of (1) how and why landscape change affects bird species diversity and persistence, (2) which components of the landscape can most effectively be manipulated to enhance population survival, and (3) estimating the long-term effects of habitat fragmentation on the population structure and function of species.Read moreRead less
Models for biodiversity futures for massively altered agricultural landscapes. Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, bo ....Models for biodiversity futures for massively altered agricultural landscapes. Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, both at patch and landscape scales. We will develop an optimization framework incorporating models of vegetation maturation and biotic responses to aid designs for placement and scheduling of replantings to give the best outcomes for biodiversity management given constraints on amounts of retired area and costs of implementation.Read moreRead less
