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)...

Assessment of ecological risk associated with irrigation in the Fitzroy basin

Phase 2: Analysis and characterisation of risk with emphasis on effects on macroinvertebrates

This project in the Fitzroy catchment in Queensland was one of three case studies used to illustrate how ERA may be employed in the management of irrigation areas in Australia. In the problem formulation stage of the ERA process community stakeholders identified issues and helped to prioritise research needs for the second phase. These were that the research should focus on the irrigation area scale and the impact of the decline of water quality on (more)...
