Litoria burrowsae
Family: Hylidae
Common name: Tasmanian Tree Frog
Description: This frog either has a light green back with light brown patches, or a dark brown back with flecks of green and light brown. A dark stripe runs from the nostril through the eye, over the tympanum (tight membrane covering the entrance to the ear) and down the side of the body. Behind the eye the stripe widens and is broken up by white blotches down the side. The belly is granular and pinkish-white. The groin and backs of the thighs are pale brown. The skin on the back is smooth with a few tubercles (lumps). The fingers are one third webbed and the toes are three-quarters webbed. The pads on the fingers and toes are large.
Size: 55 mm
Habitat: This frog often lives in rainforests, alpine country and moorlands in Tasmania. It is often found around the edges of ponds amongst the reeds and grasses.
Call: A "honk…honk…honk" sound like a goose. Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © Ron Nagorcka.
Breeding: Males call from August to February, and they breed after heavy rain most of the year round.
Eggs: Are large and laid in clusters attached to stems and twigs, under the water.
Tadpoles: Are fairly large in size and yellow brown to dark brown in colour.
Similar species: This frog can be distinguished from other species of Litoria by its distribution and colouration.
Conservation Information
Suspected threatening processes
- Exotic predators (e.g. trout, Gambusia)
- Disease/pathogens (e.g. chytrid fungus, viruses)
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. Factors affecting population size and distribution are unknown or unsubstantiated.
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: None directed primarily at the taxon.
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 2-3 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed: 1001-80000 km² (up to 1% area of Australia or about the area of Tasmania).
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: Broad range limits or habitat associations are known, but local occurrence cannot be predicted accurately.
