This work is fundamental to understanding how growth and water use by Australia's forests will be modified in the future by global change. The changes in tree leaf area and canopy structure that we seek to understand will determine forest responses to increasing atmospheric CO2 and drought. It is essential to study these changes on Australian species, because they differ from forest species elsewhere in having been largely shaped by water availability. This fundamental work will flow into predictions of future forest growth and water use in Australia, with consequences for land and water resource management as well as forestry.Read moreRead less
Sustainable futures of Australian temperate forests: An investigation of coupled carbon, water and energy exchanges from hourly to centennial timescales. Australia's forests are a critical natural resource that must be sustainably managed. We will determine the uptake/release of carbon from old growth and regrowth forests and assess the water budgets of the Melbourne water catchment. We aim to understand the current cycles of carbon, water and energy and how these may change over time (hours to ....Sustainable futures of Australian temperate forests: An investigation of coupled carbon, water and energy exchanges from hourly to centennial timescales. Australia's forests are a critical natural resource that must be sustainably managed. We will determine the uptake/release of carbon from old growth and regrowth forests and assess the water budgets of the Melbourne water catchment. We aim to understand the current cycles of carbon, water and energy and how these may change over time (hours to centuries). We will integrate our observations with state-of-the-art models to improve our predictions of how forests will respond to change. This will aid our management of forests and forested catchments to ensure sustainable and viable water resources and optimise carbon sequestration.Read moreRead less
Greenhouse gas emission from sugarcane and mangrove communities in coastal Queensland. Greenhouse gases threaten the global climate. Many estimates of vegetation as sinks and sources for greenhouse gases have a high degree of uncertainty. This project will generate important information about greenhouse gas emissions from Queensland coastal vegetation.

Greenhouse gases threaten the global climate. Many estimates of vegetation as sinks and sources for greenhouse gases have a high degree of uncertainty. This project will generate important information about greenhouse gas emissions from Queensland coastal vegetation. Characterised by moist and nutrient rich conditions, sugarcane fields and mangrove ecosystems represent significant sources/sinks of potent greenhouse gases nitrous oxide and methane. Sugarcane and mangroves exposed to different nutrient inputs will allow to (i) identify mechanisms of N2O and CH4 emission, (ii) model N2O and CH4 emissions under different nutrient and climate conditions, and (iii) control/reduce emissions by improving coastal ecosystem management.Read moreRead less
450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to a ....450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to assess its vulnerability to global climate change in relation to other nations, thereby informing national planning of landscape resource use, including primary industry, water infrastructure and carbon trading.Read moreRead less
Past and future effects of climate change on the carbon-water balance of plants. Over the coming century, climate change will profoundly impact Australian vegetation via the direct effects of elevated atmospheric carbon dioxide (CO2) on plants and the indirect effects of CO2-forced changes in rainfall and temperature, with major implications for agricultural production and water resources. This project will address these threats by providing new tools for measuring and predicting vegetation-clim ....Past and future effects of climate change on the carbon-water balance of plants. Over the coming century, climate change will profoundly impact Australian vegetation via the direct effects of elevated atmospheric carbon dioxide (CO2) on plants and the indirect effects of CO2-forced changes in rainfall and temperature, with major implications for agricultural production and water resources. This project will address these threats by providing new tools for measuring and predicting vegetation-climate feedbacks. It will determine the combined effects of elevated atmospheric CO2 and drought on the productivity of natural and agricultural landscapes, and provide the biophysical framework for developing the next generation of high-yielding, drought tolerant crop varieties for the rapidly approaching greenhouse world.Read moreRead less
Elevated carbon dioxide (CO2) effects on vegetation: repairing the disconnect between experiments and models. Ecosystem models are important tools used in a variety of applications, including predicting how vegetation uptake of carbon affects global climate, estimating carbon sequestration by natural and planted forests and determining water yield of catchments. Although there has been a massive investment in experiments to determine plant response to elevated carbon dioxide [CO2], ecosystem mod ....Elevated carbon dioxide (CO2) effects on vegetation: repairing the disconnect between experiments and models. Ecosystem models are important tools used in a variety of applications, including predicting how vegetation uptake of carbon affects global climate, estimating carbon sequestration by natural and planted forests and determining water yield of catchments. Although there has been a massive investment in experiments to determine plant response to elevated carbon dioxide [CO2], ecosystem models do not incorporate this body of data as well as they could. This project will use innovative methods to bridge the gap between experimental data and ecosystem models, resulting in significantly improved information for managers of Australia's natural resources into the future.Read moreRead less

Explaining forest responses to rising carbon-dioxide concentrations at stand scale using a new, simple model of plant carbon economy. Australia is undergoing large changes in [CO2] and rainfall patterns, with 20% decreases in annual rainfall across southern Australia over the past 30 years, and large increases in north-western Australia. The impacts of rising [CO2] and altered rainfall must be factored into Australia's environmental and water-catchment management strategies. The outcome of this ....Explaining forest responses to rising carbon-dioxide concentrations at stand scale using a new, simple model of plant carbon economy. Australia is undergoing large changes in [CO2] and rainfall patterns, with 20% decreases in annual rainfall across southern Australia over the past 30 years, and large increases in north-western Australia. The impacts of rising [CO2] and altered rainfall must be factored into Australia's environmental and water-catchment management strategies. The outcome of this project will be a new simplified forest model that has been validated for Australia's leading climate-change experiment on forests, the Hawkesbury Forest Experiment, which includes both CO2 and watering treatments. The model will be readily transferable to new sites and at regional scale, so it can be applied as a tool for future management of Australia's forests.Read moreRead less

Quantifying carbon sources and sinks and understanding the underlying processes are pre-requisites to informed policy decisions, especially as nations seek to develop strategies to manage carbon emissions and sequestration. Australia is unique because of its poor soils and high climate variability and is likely to have patterns and process of carbon that are globally different. We focus on Australia's Top-End region, but will develop tools/methods that can be applied to other important Australian hot-spots. This project will support the existing National Carbon Accounting System by providing new information on processes and spatial variability and regional budgets of carbon and water budgets that underpin our international commitments.Read moreRead less
