Green-thighed Frog

Bright green or blue-green colouring on its groin and the back of its thighs identifies the green-thighed frog (Litoria brevipalmata), which is listed as vulnerable (endangered) in NSW. This small frog (to 40 millimetres in length) emits a continuous series of “quack” or “wok” sounds.

Green-thighed frog habitat

The green-thighed frog lives in isolated populations along the coast and ranges from just north of Wollongong to south-eastern Queensland. It favours a range of habitats – from rainforest and moist eucalypt forest to dry eucalypt forests and heath, typically in areas where surface water gathers after rain.

Threats to the green-thighed frog

Any changes to drainage patterns that reduce periodic local flooding, damage to semi-permanent and ephemeral ponds and flood-prone vegetation, and reductions in water quality (mostly through grazing and pasture fertilisation) threaten the green-thighed frog. Clearing of the green-thighed frog’s habitat for agriculture, development or timber harvesting, grazing and burning have also been implicated in its decline.

Solutions – What can be done?

Land owners can help the frog to recover by avoiding burning in its moist grassy habitats between December and April; maintaining vegetation and leaf litter around ponds, dams, drainage lines and other moist areas; maintaining natural flooding patterns; protecting water bodies from pollution, and precluding the grazing and logging of frog habitat.

The Nature Conservation Trust’s conservation work on private lands is helping to protect habitat for the green-thighed frog.
