Litoria cooloolensis
Family: Hylidae
Common names: Cooloola Sedgefrog; Cooloola Tree Frog
Description: This frog is green on its back with lots of brown flecks. The tympanum (tight membrane covering the entrance to the ear) is green. The backs of the thighs are purplish-brown in colour. The belly is white or cream and granular. The skin on the back is smooth. The fingers have a small amount of webbing and the toes are half webbed. The toe pads are large.
Size: 25 mm
Habitat: This frog lives in wallum habitats, sandy freshwater lakes and lowland rainforests.
Call: A "reek…pip" sound.Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © David Stewart.
Breeding: Males call from plants in or near the water from August to May.
Eggs: Are laid in small clumps of 10-20 which are usually attached to submerged vegetation.
Tadpoles: Are small and sandy brown.
Similar species: This frog can be distinguished from Litoria fallax and Litoria bicolour by its colouration and lack of a brown head streak.
Conservation Information
Suspected threatening processes
- Direct human impact/urbanisation/tourism
- Inappropriate catchment management, including degraded water quality
- Habitat modification (e.g. vegetation clearing, invasive weeds)
Population size: An estimate of the total number of adults present in the species entire range is 10001-50000 individuals, or size is unknown but suspected to be large. Some factors affecting population size and distribution are known, but 1 or more major factors are unknown.
Population trend in Australia over the past 50 years: Population trend unknown; no information on habitat changes.
Knowledge of population trend in Australia: Not currently monitored.
Population concentration: Not known to concentrate or exist in discrete locations. (e.g. the number of sites in which individuals group together either seasonally, such as breeding sites, or they may occupy discrete habitat patches within the broader landscape, such as discrete water bodies or drainage units.)
Ongoing management activities in Australia: Management mostly related to enforcement of conservation laws.
Reproductive potential for recovery: The average number of eggs deposited per adult female per year is 201-1000 eggs/female/year. Minimum age at which females are known or suspected to first reproduce is <2 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed: 101-1000 km².
Distribution trend: Area occupied has declined by < 25%. (This is an estimate of change in the portion of the total range that is occupied or utilised; it may not equal the change in total range.)
Knowledge of distribution in Australia: Distribution is well known and occurrence can be accurately predicted throughout the range.
