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

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
Understanding and manipulating stress physiology of eucalypt seedlings to improve survival and growth. Eucalyptus globulus and E. nitens are the major species being established to meet the 2020 Vision (Anon 1999) of trebling Australia's plantation estate. Seedling mortality and/or reduced growth after planting, linked to the transition from ideal growing conditions in the nursery to stressful conditions (high drought and browsing risk) at the planting sites, significantly increase the costs of ....Understanding and manipulating stress physiology of eucalypt seedlings to improve survival and growth. Eucalyptus globulus and E. nitens are the major species being established to meet the 2020 Vision (Anon 1999) of trebling Australia's plantation estate. Seedling mortality and/or reduced growth after planting, linked to the transition from ideal growing conditions in the nursery to stressful conditions (high drought and browsing risk) at the planting sites, significantly increase the costs of plantation production. By investigating physiological mechanisms of seedlings and their responses to drought and browsing stress during establishment in the field, methods for the production of seedlings acclimated to drought or browsing stress will be developed. The research outcomes will help maximise the financial return on over $28 M per annum being invested by the 8 project partners in seedling production and planting over 80, 000 ha per year for the next 19 years to meet the requirements of Vision 2020.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
