The Coorong lagoon, at the end of the Murray River in South Australia, has faced a tough few decades as successive droughts have made the water saltier and more difficult for threatened species to live in.
But a new technique, developed by a collaboration of half a dozen different institutions, has just been shown to improve the health of the lagoon floor (its benthic health).
It involves adding more dirt – and some worms – from healthier areas, to kickstart a process called “bioturbation”.
“Bioturbation is pretty simple,” explains Dr Orlando Lam-Gordillo, a researcher at Flinders University and lead author on a paper describing the research, which is published in Science of the Total Environment.
