Changes to river flows are having a ‘damming’ impact on platypuses


A three-year study has confirmed that significant alterations to flow regimes by dams can have a big impact on downstream platypus populations.

Some large dams are having a serious impact on downstream platypus populations, an extensive three-year study by UNSW scientists has found.

The researchers from UNSW Sydney’s Platypus Conservation Initiative in the Centre for Ecosystem Science (CES) say the natural flow regime needs to be replicated on dammed rivers if platypus populations are to recover in areas below large dams.

“The way dams are managed, such as the timing and volume of the release of water, can significantly impact on platypuses living downstream,” lead author Dr Tahneal Hawke said. MORE
