Good water quality is vital for the survival of Rottnest’s frog populations which are genetically distinct from mainland populations. The brackish wetlands on Rottnest (swamps and seeps) provide very important breeding sites and habitat for this species.
Motorbike Frogs are one of the most commonly seen frogs in the South-West of WA. Although they are sometimes called tree frogs, this species mainly lives on the ground.
Breeding season for Motorbike Frogs is early spring to summer. Typically the male will sit on reed beds when calling for a mate. The call has two components: a long low growl which sounds like a motorbike changing gear followed by a series of low growls. Their call can only be heard within a few hundred metres.
