Assessing biodiversity outcomes from waterpoint interventions in the patchy, gibber-gilgai arid rangelands

“Domestic and feral herbivores need daily access to water during summer, and every few days during winter. The risk to biodiversity and ecosystem function depends on the type of herbivore activity, its intensity, and how long an area is exposed to grazing and seasonal conditions (rainfall). We explore whether waterpoint manipulation is a useful management tool for achieving biodiversity and ecosystem outcomes in the arid grazing lands of remote Australia. We used the (more)...

Managing root-zone salinity for irrigated horticultural crops in winter rainfall zones of Australia

A better understanding of plant requirements and the highly efficient management of water has led irrigators to apply water to accurately meet crop needs. This has meant a considerable reduction in the amount of water flushing through the root-zone. As a result, soil salinity levels have risen. Current drought conditions and low water allocations are likely to result in even less water being used to flush salts from the root-zone. The declining quality of water resources means that actively removing (more)...
