Litoria jervisiensis
Family: Hylidae
Common name: Jervis Bay Tree Frog
Description: This frog is grey-brown to dark brown on its back, with darker flecks and spots. There is a faint dark broad patch running down the back. Some individuals also have a pale stripe that runs down the spine. A dark stripe runs from the snout, through the eye and tympanum (tight membrane covering the entrance to the ear), to the base of the arm. There is a white stripe from beneath the eye to beyond the angle of the jaw. The groin, backs of the thighs, and armpits are all red-orange. The belly is cream or yellow and granular. The finger and toes pads are large and the toes are two-thirds webbed.
Size: 60 mm
Habitat: This frog lives in wet scleropyhll forests, coastal heathlands and swamplands.
Call: Two or three high pitched squeals.Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © David Stewart.
Breeding: Occurs from March to September, usually after rain.
Eggs: Are laid in small clusters, attached to stems.
Tadpoles: Are medium sized and clear golden yellow in colour, with darker areas.
Similar species: This frog can be distinguished from Litoria littlejohni by its call and the white stripe beneath its eye.
Conservation Information
Suspected threatening processes
- Exotic predators (e.g. trout, Gambusia)
- 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 >50000 individuals. 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 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.
