‘The sad reality is many don’t survive’: how floods affect wildlife….
For over two decades, bull sharks have called a Brisbane golf course home after, it’s believed, a flood washed them into the course’s lake in 1996. Now, after severe floods connected their landlocked home back to the river system, these sharks have gone missing, perhaps attempting to seek larger water bodies.
This bizarre tale is one of many accounts illustrating how Australia’s wildlife respond to flooding. But the sad reality is many don’t survive. Those that do may find their homes destroyed or, like those bull sharks and others, find themselves displaced far from their original homes or suitable habitat.
The RSPCA and other wildlife care organisations have received hundreds of calls to help rescue and care for stranded animals. But the true toll on wildlife will remain unknown, in part because we know surprisingly little about the impacts of floods on wildlife.
Still, as many animals have amazing abilities to survive fire, so too do many possess the means to survive or even profit from floods. After all, Australia’s wildlife has evolved over millions of years to survive in this land of extremes.
How wildlife responds to floods
Floods rapidly turn land habitats into underwater habitats, allowing aquatic animals to venture into places you wouldn’t expect. Flooding during northern Australia’s annual wet season, for example, sees crocodiles occasionally turn up in people’s backyard pools.
