Environmental Water Allocation required to sustain macroinvertebrate species in ephemeral streams

Project Objectives: To determine the key drought refuges used by macroinvertebrate species in intermittently-flowing streams and determine the level of threat to each refuge posed by prolonged drying and unpredictable flow regimes To determine the role played by different types of drought refuge in restocking macroinvertebrate populations in rivers and therefore the consequences for river communities of loss of each type of drought refuge. To determine the (more)...

Watering wetlands, Impediments and challenges to the transfer of knowledge between wetland managers and scientists

The degradation of Australia’s wetlands has brought into sharp focus the need to manage factors such as altered flow and water regimes. Exchanging knowledge between wetland managers and wetland scientists and putting knowledge into practice is an essential part of this management. Yet environmental watering of wetlands is a relatively new type of intervention, especially where engineering infrastructure is used. It is largely restricted to south eastern Australia. Thus, while there is (more)...

The Bayesian Network Models for Environmental Flow Decision-making

This final report summerises the activities and outcomes of the Land & Water Australia Project - Environmental Flow Bayesian Network Decision-Making Framework. The development of two Bayesian Network models used as a decision-support tool for determining environmental flows in major rivers in Australia are reported on. The first eFlows BN model was for the Latrobe River in Victoria, a river system that is highly regulated and (more)...

Mallee Fire and Biodiversity Project

Project Aim:

To identify the properties of habitat mosaics produced by fire that enhance the persistence and status of a broad range of taxonomic groups (birds, mammals, reptiles, key invertebrates and plants) in eucalypt-dominated mallee habitats.

Ecohydrological regionalisation of Australia

This report is a result of the Ecohydrological regionalisation of Australia project.

The project classified Australia’s unregulated riverine flow regimes to provide a rigorous foundation for future ecological investigations of the importance…

Land use effects on soil nutrient enrichment: risks for weed invasion

This project examined various soil and vegetation properties of remnant eucalypt grassy woodlands under different livestock grazing regimes within agricultural landscapes on the southern tablelands and south west slopes of N.S.W. All woodlands contained…

Delivering Sustainability through Risk Management

Any future expansion of irrigated agriculture in Australia is likely to occur in northern Australia. The region of Australia north of the tropic of Capricorn has abundant water resources — over 60% of the nations surface water run-off (NLWA 2001). However, there are concerns that in the rush to develop this new bonanza we will simply make the same mistakes that plague existing irrigation systems. These include: water logging, salinization, soil acidification, erosion, (more)...
