Frogs can be heard at Lake Pertobe all year round. Some of the more common species include Litoria ewingii Southern Brown Tree Frog, Limnodynastes tasmaniensis Spotted Marsh Frog, Limnodynastes dumerilii Eastern Banjo Frog and Limnodynastes peronii Striped Marsh Frog.
Frogs can be a good indicator of waterway health due to their water dependent life cycle. Their sensitive skin, eggs and tadpoles can be susceptible to changes in water quality. The release of unwanted aquatic plants and animals is a major threat to native aquatic flora and fauna including frogs.
Frog Calls
The Striped Marsh Frog call is a single short “tuk’ that is repeated every few seconds, when in chorus this can sound like tight strings being plucked. Peak calling season is from September through to April
The Eastern Banjo Frog gets its name from the sound of its call as it is often likened to someone playing the banjo wrong. Peak calling season is from September to December
The Southern Brown Tree Frog call is a fast high pitched ‘creeeee cree cree cree’ repeated every few seconds. Peak calling season is June to November
The call of the Spotted Marsh Frog varies across states, in southern Victoria and Tasmania is it a distinct ‘click’ sound, similar the sound of rhythm sticks clacking together. Peak calling season is September to December.
