Australia is a country of droughts and flooding rains — and that contrast is nowhere more starkly illustrated at the moment than SA's Riverland, where water is seeping into desiccated landscapes for the first time in decades.
Mr Willis said the environment was likely to thrive for years after the floodwaters receded.
"There's a unique, once-in-many-decades opportunity to develop knowledge about how we manage wetlands between this and the next flood." But the flood was also creating a lot of stress on some species which could see some species decrease in numbers while invasive species like the carp are likely to increase."We might see some modest-scale fish kills here; people might notice fish at the surface trying to get oxygen," Mr Willis said.
