The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Summary
Environmental Research Isotope Ratio Mass Spectrometer (ERIRMS). The projects supported by this facility are esential to: sustainable management of Sydney's surface and groundwater; understanding food webs and trophic interactions in Sydney Harbour and elsewhere on the eastern seaboard; developing predictive models for the impacts of climate change on Australia's forests, especially carbon sequestration and water yield; understanding the trade-offs involved in managing fire risks through prescr ....Environmental Research Isotope Ratio Mass Spectrometer (ERIRMS). The projects supported by this facility are esential to: sustainable management of Sydney's surface and groundwater; understanding food webs and trophic interactions in Sydney Harbour and elsewhere on the eastern seaboard; developing predictive models for the impacts of climate change on Australia's forests, especially carbon sequestration and water yield; understanding the trade-offs involved in managing fire risks through prescribed burning, especially trade-offs involving carbon and water; and understanding and predicting air quality and the effects of emissions from cars, industry, fires and natural sources.

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
The Sustainable Effluent Irrigation Project - Effects of effluent irrigation on soil sodicity and groundwater quality. The land application of recycled municipal effluent is now regularly practised by a number of local authorities and agencies responsible for centralised collection of wastewater, its treatment and disposal. Treated municipal effluent is often land applied and used to grow hardwood plantations. Hardwood plantations are very effective in producing large amounts of biomass and also ....The Sustainable Effluent Irrigation Project - Effects of effluent irrigation on soil sodicity and groundwater quality. The land application of recycled municipal effluent is now regularly practised by a number of local authorities and agencies responsible for centralised collection of wastewater, its treatment and disposal. Treated municipal effluent is often land applied and used to grow hardwood plantations. Hardwood plantations are very effective in producing large amounts of biomass and also assist agencies in off-setting wastewater treatment and disposal costs associated with advanced wastewater treatment to remove nutrients. This project will examine the effects of effluent irrigation on soil chemistry and groundwater quality at two hardwood plantations in the Hunter Valley, NSW. It is increasingly clear that large-scale reuse schemes, particularly those involving hardwood plantations, must be designed to be sustainable and have no significant impact on soil chemistry (increasing sodicity) and groundwater. This project will develop irrigation regimes for hardwood plantations which will promote soil productivity and optimize effluent application rates for pollutant removal and biomass production.

Forestry effects on headwater ecosystem health: a multi-catchment experiment. Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stre ....Forestry effects on headwater ecosystem health: a multi-catchment experiment. Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stream ecosystems to supplement 4 years of hydrological data collected by Forests NSW from 5 experimental catchments. Results will provide a firmer scientific basis for ecologically sustainable harvesting in this forest type, with flow-on benefits to our national economy, biodiversity, and environment.Read moreRead less
Functional and structural characterisation of Defective embryo and meristems (Dem) proteins involved in plant development. The proposed research will lead to advances in understanding the regulation of plant development, a process impacting on agriculture, environmental management and human health, areas designated as national research priorities.

The proposed research will lead to advances in understanding the regulation of plant development, a process impacting on agriculture, environmental management and human health, areas designated as national research priorities. This understanding is required for modifying plant growth and architecture to fit particular environments, for example generating plants with more extensive and deeper roots to mine the soil moisture and nutrients to enhance crop productivity in Australia, and maintaining the competitive advantage of Australian agriculture in view of the range of environmental conditions encountered in this country. The project will also contribute to the health of the Australian population through consumable plants in the diet.Read moreRead less
