Booroolong frog revival

Booroolong frog revival

22.01.2013 - Posted by Clare Ferguson
Here’s another good example of why rivers need a decent flood from time to time: populations of the nationally endangered booroolong frog have flourished since the March 2011 floods in the Upper Murray region, according to a recent collaborative survey by the Victorian Department of Sustainability and Environment, NSW Office of Environment and Heritage and Parks Victoria.

The booroolong frog had significantly declined in numbers as a result of disease and drought, as well as the typical post-European settlement impacts on the landscape. In Victoria, there are now only two known populations of booroolong frog, both located in the Upper Murray region. The one in eighty year ARI flood there in 2011 exposed and deposited rocky cobble along the stream edges, restoring ideal breeding habitat for the frog. It seems the booroolong, one of Victoria’s rarest frogs, has taken to the new breeding habitat quite nicely and has wasted no time getting down to business.

The booroolong frog's response to the high flow event is encouraging. It reinforces the ecological importance of having a range of flows along the stream. It also illustrates how a species in decline can recover if appropriate flows are returned to the system, even when the species has been in decline for some time.
