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.

Setting rehabilitation targets for regulated floodplain wetlands: linking system structure and function. Limited understanding of ecosystem processes in floodplain wetlands impedes adaptive management strategies for combating the decline in aquatic productivity and biodiversity. This project addresses three knowledge gaps critical for effective floodplain wetland management: 1) hierarchical spatial and temporal patterns of structural diversity; 2) correspondence between patterns of structural d ....Setting rehabilitation targets for regulated floodplain wetlands: linking system structure and function. Limited understanding of ecosystem processes in floodplain wetlands impedes adaptive management strategies for combating the decline in aquatic productivity and biodiversity. This project addresses three knowledge gaps critical for effective floodplain wetland management: 1) hierarchical spatial and temporal patterns of structural diversity; 2) correspondence between patterns of structural diversity, rates of system production, and food web structure, and 3) conceptual models of relationships between hydrologic regime and wetland structure and function. The project will improve understanding of the impacts of regulation on floodplain wetlands, contribute to adaptive management, and set rehabilitation targets for delivery of environmental flows for ecosystem sustainability.Read moreRead less
Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more n ....Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more natural flood regime, planting native species and reducing competition from dense understorey vegetation. In this way, the project aims to test and advance ecological theory, guide wetland restoration and inform management plans for saving Victoria’s iconic fauna.Read moreRead less
Restoring functional links between riparian zones and streams by enhancing structural retention. This project aims to test whether structural retention, whereby plant detritus (logs, bark, leaves) is trapped and retained within river channels, can offset the impacts caused by widespread clearance of vegetation along river banks, a widespread problem in Australia and the world. Theoretically, retention is a major environmental driver of ecosystem change in rivers, but this has rarely been tested, ....Restoring functional links between riparian zones and streams by enhancing structural retention. This project aims to test whether structural retention, whereby plant detritus (logs, bark, leaves) is trapped and retained within river channels, can offset the impacts caused by widespread clearance of vegetation along river banks, a widespread problem in Australia and the world. Theoretically, retention is a major environmental driver of ecosystem change in rivers, but this has rarely been tested, particularly in a restoration context. The aim of this project is to show that increasing retention results in higher species diversity, thus providing managers with a relatively straightforward method for improving the environmental conditions of rivers, while simultaneously testing three hypotheses about rectifying ecosystem degradation caused by human impacts.Read moreRead less
Restoration trajectories of stream ecosystems degraded by urban stormwater runoff: a large-scale experiment in urban hydrology and stream ecology. This project aims to assess innovative dispersed stormwater retention systems in catchments for protection and restoration of urban streams. It will improve the ecological condition of several study streams and provide scientific support for new policies and practices for urban water management, with multiple environmental and community benefits.
Assessing the impact of habitat restoration on the rates of recovery of four native fish species using advanced statistical models. This project will develop statistical modelling tools to assess how quickly threatened native fish populations recover following habitat restoration. The outcome of this project will aid in understanding the use of habitat restoration in managing endangered stocks of Murray Cod, Trout Cod, Silver Perch and Golden Perch in the Murray River.
The importance of dispersal in maintaining biodiversity of aquatic plants in landscapes. Aquatic plants improve water quality and provide habitat for aquatic animals, which underpin industries such as tourism and commercial fisheries critical to economies in regional areas and across Australia. Preserving plant biodiversity of aquatic ecosystems is vital to preserve these benefits. Dispersal plays a critical role in maintaining plant biodiversity and requires understanding at landscape scales. T ....The importance of dispersal in maintaining biodiversity of aquatic plants in landscapes. Aquatic plants improve water quality and provide habitat for aquatic animals, which underpin industries such as tourism and commercial fisheries critical to economies in regional areas and across Australia. Preserving plant biodiversity of aquatic ecosystems is vital to preserve these benefits. Dispersal plays a critical role in maintaining plant biodiversity and requires understanding at landscape scales. This project will identify appropriate approaches for the conservation of plant biodiversity in aquatic ecosystems through an improved understanding of the contribution of wind, water and waterbirds in the dispersal of aquatic plants. This project will also identify water flow regimes that promote a diverse and sustainable aquatic flora.Read moreRead less
Can dispersed, catchment-scale, urban stormwater retention restore stream ecosystems? This project is a world-first, catchment-scale, experimental test of the benefits of new stormwater treatment approaches to stream health. The project, a collaboration with Melbourne Water and the Shire of Yarra Ranges, integrates river, urban stormwater and water resource management for multiple benefits. It should accelerate the uptake of smart, sustainable technologies in stormwater use and management, and ....Can dispersed, catchment-scale, urban stormwater retention restore stream ecosystems? This project is a world-first, catchment-scale, experimental test of the benefits of new stormwater treatment approaches to stream health. The project, a collaboration with Melbourne Water and the Shire of Yarra Ranges, integrates river, urban stormwater and water resource management for multiple benefits. It should accelerate the uptake of smart, sustainable technologies in stormwater use and management, and identify better investment strategies for urban water and river management. The robust testing of the effect of new treatment design objectives by a catchment-scale experiment will have a strong impact on research in stream ecology and urban water management.Read moreRead less
