Adaptive management of arid and semi-arid ecosystems. Australia’s arid zones contain some of the world’s most threatened ecosystems. Management must begin immediately, but our understanding of these fragile species and ecosystems is currently very limited. This project will develop and apply new research in Adaptive Management (“learning by doing”) to ensure the persistence of these rare places.
Ecohydrologic functioning of ephemeral streams. This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use a ....Ecohydrologic functioning of ephemeral streams. This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use and numerical modelling, to assess resilience of ephemeral streams to changes in flows resulting from mining activities and climate-related shifts in recharge. Expected outcomes of the project include providing appropriate context for evaluating and adapting management to conserve scarce water resources. This project should significantly contribute to the sustainable management of both mineral and groundwater resources.Read moreRead less
Vulnerability of Australian savannas to climate change and variability. Australian savannas are productive and are culturally and biologically significant landscapes, but they are vulnerable to climate change. This project will determine savanna function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.
