This project will protect pine plantations (representing 57% of Australia's $3.3 billion pa forestry industry) from the dual threat of exotic pests and climate change. Sirex wood wasp has been well controlled until the recent, unprecedented, increase of ips bark beetles. The ips beetle is now disrupting biological control of sirex by its feeding activity so work is required to understand and combat this effect. The work is made more urgent by looming climate change because storm-damage, drought and heat stressed trees are especially vulnerable to sirex attack. It is estimated that this novel pest management approach could save the industry at least $188 million pa based on a conservative estimate of reducing losses by 10%.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

This project aims to test a ‘gene to plantation’ approach for the management of pests in softwood forestry. The project aims to focus on the stripping of bark from Pinus radiata trees by mammals: a major threat to tree productivity in many regions of Australia and an economic burden for forestry companies. The project aims to use a wide complement of P. radiata germplasm to link genetics, bark defensive chemistry and susceptibility to damage. It aims to identify genotypes with increased resistance, unravel defensive tree traits, screen for genetic markers and identify specific gene regions correlated with trait variation, and examine cross-correlations with other major tree productivity traits.Read moreRead less

Eucalyptus globulus is the most important plantation eucalypt in Australia and a model for tree genetic research. The project aims to study the quantitative genetic architecture of this species, focusing on traits of economic significance, and provide new insights into: the relative importance of non-additive genetic effects, including maternal and reciprocal effects; the importance of indirect genetic effects, particularly on the competitive interactions amongst trees; and the genetics of traits impacting the production of emerging plantation products such as veneer. This information is needed to improve genetic evaluation models and to better target germplasm to environments and products.Read moreRead less
Quantitative genetics of Eucalyptus globulus. Eucalypt plantations in Australia have expanded rapidly over the last decade. With increasing market competition from overseas plantations for both pulp and solid wood products, Australia must maintain a competitive edge through efficiencies in production and product quality. Breeding and deployment of genetically superior planting stock is part of the solution. With global climate chance and requirements for re-afforestation in drier zones, there ....Quantitative genetics of Eucalyptus globulus. Eucalypt plantations in Australia have expanded rapidly over the last decade. With increasing market competition from overseas plantations for both pulp and solid wood products, Australia must maintain a competitive edge through efficiencies in production and product quality. Breeding and deployment of genetically superior planting stock is part of the solution. With global climate chance and requirements for re-afforestation in drier zones, there is an increasing requirement to genetically improve drought tolerance. This project will provide genetic information and strategies to back Eucalyptus globulus breeding and deployment programs for traditional as well as drier environments. 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
Determining generic indicators of stress in eucalypt leaves for application to the remote sensing of canopy condition and productivity modelling. Biotic and abiotic stresses induce generic alterations of leaf chemistry (e.g. chlorophyll, anthocyanins).

Biotic and abiotic stresses induce generic alterations of leaf chemistry (e.g. chlorophyll, anthocyanins). We will explore the behaviour of eucalypt leaf reflectance to changes in leaf cellular chemistry and structure arising from exposure to a range of stressful factors. We will relate leaf reflectance to physiological processes using a research radiation interception model. We will report on a) the potential integration of data related to stress, into process-based models for eucalypt plantation growth and b) the exploitation of generic reflectance indicators of stress in the remote acquisition of high resolution multispectral imagery with potential to spatially quantify plantation eucalypt health.Read moreRead less
Understanding plant uptake of organic and inorganic nitrogen for optimal fertiliser application in forestry. Nitrogen (N) in soils occurs in both organic and inorganic forms. Plants can take up inorganic N - nitrate and ammonium - but, on average, these account for only 5% of the soluble N in soils. Recent evidence suggests that plants may be able to tap into some of the 95% of N that occurs in organic forms. We will investigate the importance of organic N uptake for two plantation Eucalyptus sp ....Understanding plant uptake of organic and inorganic nitrogen for optimal fertiliser application in forestry. Nitrogen (N) in soils occurs in both organic and inorganic forms. Plants can take up inorganic N - nitrate and ammonium - but, on average, these account for only 5% of the soluble N in soils. Recent evidence suggests that plants may be able to tap into some of the 95% of N that occurs in organic forms. We will investigate the importance of organic N uptake for two plantation Eucalyptus species by tracing the uptake of different N forms by bacteria, fungi and eucalypts. This information will redefine what is meant by 'available N' and will guide the development of a new test for soil N status.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.

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
