Distribution and Habitat
Country distribution from AmphibiaWeb's database: Australia
Ranging from the Queensland border south down the Great Dividing Range almost to the
Victorian border. Has not been recorded from the Northern Tablelands during the past 15 years
despite extensive surveys. The only extant population in Northern New South Wales is near
The extent of occurrence of the species is approximately 135700 km2, however, the area of
occupancy is only approximately 10km2 and is severely fragmented.
There have been very few records of the species in the past 5 years and the species is believed
to have declined over its entire range.
Life History, Abundance, Activity, and Special Behaviors
A highland species (200 – 1000m asl) associated with western-flowing rocky streams on the
slopes and tablelands of the Great Dividing Range. Streams are slow-flowing and bordered by
Males begin calling in August from rocks in or near the water. Most active at night but also often
found in daylight on rocks on the waters edge.
Trends and Threats
Massive historic declines and continuing decline in range and numbers.
Area of occupancy < 10km2 and severely fragmented.
Introduced fish occur in many streams where the species has been recorded. Introduced fish
exert predatory pressure upon tadpoles of this species. Land clearing, forest grazing and timber
harvesting have occurred adjacent to or in the headwaters of catchments in which the species
has been recorded. Flow modification and weed invasion (particularly by willows) has also
occurred along many streams where the species occurs.
Development of a management plan is underway, but much research is needed as is protection
and rehabilitation of habitat.
