How does forestry impact headwater streams? Although headwater streams make up much of the catchment of rivers, the effects of forestry on instream species composition, habitat types, and ecosystem functions remain uninvestigated. We aim to fill these three gaps so that managers can: 1. determine whether stream side buffers are necessary and 2. identify which species and ecosystem functions are the most sensitive and reliable variables for future monitoring of instream ecosystem health.

Summary
CaGaWaLo: regulation of carbon gain and water loss by woody vegetation. Trees and shrubs are widely perceived as central to solving problems of national and international significance. Seed funding is sought to facilitate establishment of a research network focused on their ability to sequester carbon and transmit water to the atmosphere. The proposed network is broadly based in plant physiology and ecology and contains a strong cross-section of leading international expertise in relevant sub- ....CaGaWaLo: regulation of carbon gain and water loss by woody vegetation. Trees and shrubs are widely perceived as central to solving problems of national and international significance. Seed funding is sought to facilitate establishment of a research network focused on their ability to sequester carbon and transmit water to the atmosphere. The proposed network is broadly based in plant physiology and ecology and contains a strong cross-section of leading international expertise in relevant sub-disciplines. By leveraging the huge pool of international expertise and focusing on a range of scales (from molecular to biosphere scales), this network will yield new ideas and approaches that will produce outputs and outcomes of national significance.Read moreRead less
Cellular automata model of forest stands to predict size-class distribution and survival. Existing forest growth models predict well stand level processes such as growth. However, they provide little information on forest structure and how this affects commercial forest products, risks of growing plantations and stand dynamics that determine carbon sequestration and water-use and result in age-related decline in productivity and self-thinning. By using newly developed technology to quantify in ....Cellular automata model of forest stands to predict size-class distribution and survival. Existing forest growth models predict well stand level processes such as growth. However, they provide little information on forest structure and how this affects commercial forest products, risks of growing plantations and stand dynamics that determine carbon sequestration and water-use and result in age-related decline in productivity and self-thinning. By using newly developed technology to quantify inter-tree competition, tree level resource supply, between tree genetic differences and the importance of chance events this project will draw on complexity theory to develop an innovative model that partitions stand level production to forecast the growth and size of individual trees.Read moreRead less
Managing for persistence of the saproxylic biota in production forest landscapes. The pattern of 'fragmentation' and 'matrix alteration' being examined in this study mirrors not just other areas of Tasmania but also much of south-eastern Australia. The research addresses a conservation biology issue in a new and novel way and has been developed with, and is supported by an industry partner working in multiple-use forest management, so the research provides both immediate applied and strategic o ....Managing for persistence of the saproxylic biota in production forest landscapes. The pattern of 'fragmentation' and 'matrix alteration' being examined in this study mirrors not just other areas of Tasmania but also much of south-eastern Australia. The research addresses a conservation biology issue in a new and novel way and has been developed with, and is supported by an industry partner working in multiple-use forest management, so the research provides both immediate applied and strategic outcomes. These outcomes directly relate to forest sustainability especially the management of the biodiverse dead wood habitat including the harvesting of fuelwood.Read moreRead less
Understanding the impact of global environmental change on Australian forests and woodlands using rainforest boundaries and Callitris growth as bio-indicators. Human-caused climate change is a fact but the ecological responses are uncertain. These could include accelerated tree growth, expansion of rainforest, and thickening of woodlands, although cessation of Aboriginal firing may be equally important. We will provide a historical context to understand how and why Australian forests have change ....Understanding the impact of global environmental change on Australian forests and woodlands using rainforest boundaries and Callitris growth as bio-indicators. Human-caused climate change is a fact but the ecological responses are uncertain. These could include accelerated tree growth, expansion of rainforest, and thickening of woodlands, although cessation of Aboriginal firing may be equally important. We will provide a historical context to understand how and why Australian forests have changed. Our results will inform management and policy debates about (i) rainforest conservation (ii) the role of fire in forest management (iii) the likely impact of increased CO2 ('fertiliser effect') of forest productivity (iv) national carbon accounting and (v) the consequences of climate change on forest ecosystems, particularly the respective wetting and drying trends in the north and south of Australia.Read moreRead less
Social acceptability of forest management options: Landscape level visualisation and evaluation. Sustainable forest policy requires social acceptance. Prior research has investigated relative acceptability of options at a forest stand level. However, we have insufficient understanding of public acceptance of forest management systems implemented across the wider landscape. Only detailed knowledge of public reaction to social, environmental and economic impacts and the trade-offs involved can red ....Social acceptability of forest management options: Landscape level visualisation and evaluation. Sustainable forest policy requires social acceptance. Prior research has investigated relative acceptability of options at a forest stand level. However, we have insufficient understanding of public acceptance of forest management systems implemented across the wider landscape. Only detailed knowledge of public reaction to social, environmental and economic impacts and the trade-offs involved can reduce the divisive nature of the forest management debate. This project will use interactive, still and animated computer representations of landscapes to examine social acceptability of alternatives to clearfell harvesting. This knowledge will be integrated with biophysical data to improve management of forested landscapes.Read moreRead less
Acceptability of Forest Harvesting Systems. Fierce public debate over forest management has prompted forest agencies to develop and test alternative harvesting systems. This project will examine community response to these harvesting and regeneration options. It will avoid the biases of existing research by developing an interactive simulation of the forest environment that will allow participants to view visual, ecological and economic outcomes of harvest options, as well as changes over time ....Acceptability of Forest Harvesting Systems. Fierce public debate over forest management has prompted forest agencies to develop and test alternative harvesting systems. This project will examine community response to these harvesting and regeneration options. It will avoid the biases of existing research by developing an interactive simulation of the forest environment that will allow participants to view visual, ecological and economic outcomes of harvest options, as well as changes over time as forest regenerates. Public judgements of the acceptability of harvesting options will be integrated with the outcomes of related biophysical studies to identify socially and ecologically sustainable management options for Australian native forests.Read moreRead less

Mycosphaerella, a defoliating fungal pathogen of eucalypts, has the potential to change markedly the economics of plantation development. This research will explore the fundamental physiological and pathological processes associated with the disease, link these findings into established process-based models of forest plantation growth for predictive purposes and utilise hyperspectral remote sensing techniques to scale impact from the tree to plantation level. In doing this research not only are questions of key importance to an important and growing industry sector addressed, but an innovative approach to disease impact assessment established and a skills base and methodology widely applicable to other tree and agricultural disease problems established.Read moreRead less
Linking environmental stress in pine plantations to bark stripping by browsers and fungal attack: developing novel options for management. The Australian forest industry, under the pressure of certification requirements, is moving towards a more integrated, reduced chemical, environmentally sustainable approach to protecting forest. Novel insights into the stress biology of pine will provide valuable information that will underpin efforts to reduce risk e.g. the matching of specific genotypes to ....Linking environmental stress in pine plantations to bark stripping by browsers and fungal attack: developing novel options for management. The Australian forest industry, under the pressure of certification requirements, is moving towards a more integrated, reduced chemical, environmentally sustainable approach to protecting forest. Novel insights into the stress biology of pine will provide valuable information that will underpin efforts to reduce risk e.g. the matching of specific genotypes to site so that pest resistance can be maintained even under environmental stress conditions. By understanding the 'attraction' factor of stressed pine to wallabies we will develop and test an urgently and nationally required diversionary feed for this browser. Lethal control involving poison is becoming increasingly restricted.Read moreRead less
