Assessment Information
Red List Category & Criteria:
Least Concern ver 3.1
Year Published:
2004
Date Assessed:
April 30, 2004
Annotations:
Needs Updating
Justification:
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification,
presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in
a more threatened category.

Population
Current Population Trend: Stable
Habitat and Ecology (see Appendix for additional information)
It is an inhabitant of dry regions. It is found in woodlands, shrublands, mallee and open grassland as well
as disturbed areas. It becomes active after rains and is buried in loam or clay soils much of the time. It
breeds after heavy rain and flooding. Males call whilst floating in open, shallow and still water. Eggs are
clumped together and are wrapped around and adhered to submerged vegetation in ponds, dams,
ditches and flooded clay pans. Tadpoles are aquatic and take 4-7 months to develop. In "habitat
preferences" "other" refers to "clay pans".
Systems: Terrestrial, Freshwater
Threats (see Appendix for additional information)
Habitat loss/degradation associated with the expansion of agro-industry farming is a threat in some
parts of the species' range.
Conservation Actions (see Appendix for additional information)
The range of the species includes several protected areas.
