Thus, proactive strategies that address these
problems, such as restoration in catchments and
riverbank zones; provision and maintenance of refuge
habits; some degree of flow in systems where much

fish around constructed barriers in the system, and the
identification and active conservation of valuable
ecosystems and particular biota, all contribute in
minimising the impacts of drought. Already much
investment is occurring in these forms of restoration
across large areas of Australia, although arguably
