Tree frog bleats its existence in Gippsland
By Celine Foenander
A frog which has never been seen before in Victoria has been discovered by an ecologist undertaking survey work in the Genoa River Valley near Mallacoota. The Bleating Tree Frog is usually found in New South Wales and Queensland.
Graeme Gillespie was commissioned by the Department of Sustainability and Environment to locate the Southern Barred Frog in waterways in far East Gippsland.
Little did he know he was to stumble across something very unusual.
“We were just driving along, stopping at various points on the road, listening to see what was calling from dams and from roadside pools and at one of the sites we stopped at, all of a sudden we heard that very distinctive call,” Graeme told ABC Gippsland’s Mornings program.
“My brain did a slight back-flip. I wasn’t quite sure what I was hearing at first.”
Graeme had heard the Bleating Tree Frog, Litoria dentata.
The species is known to call after heavy rainfall and on a warm night.
“The call of a frog is a very important part of identification. It’s also an important way of finding frogs. Some species you can only find when they’re calling, they’re very secretive,” Graeme said.
However, it wasn’t a lone call. There were two or three calls from a swampy area of a paddock and then a rousing chorus further along the road.
Graeme suspects the species may have in the area for a long time and never recorded.
“It’s really too far for a frog this size to migrate. Frogs are relative sedentary, they don’t really pack their bags and hop across the landscape, particularly in periods of drought,” he said.
“While there has been amphibian survey work, it hasn’t been a huge amount and it certainly hasn’t been comprehensive.”
The species is not endangered or threatened nationally.
