Litoria andiirrmalin
Family: Hylidae
Common name: Melville Range Tree Frog
Description: This large frog is mottled brown on its back with irregular cream markings. Two pale stripes run down the back on either side of the spine. The belly is cream and the throat is a darker colour. The skin on the back is mainly smooth. The toes are fully webbed while the fingers have no webbing. The finger and toe pads are large.
Habitat: This frog lives in mesophyll vine forests and Melaleuca emergents in the Melville Range, Queensland. It is often associated with small rocky streams and waterfalls.
Call: Not described.
Similar species: This frog can be distinguished from Litoria nannotis by its lack of finger webbing and smooth back.
Conservation Information
Suspected threatening processes
- None stated
Population size: An estimate of the total number of adults present in the species entire range is 0-1000 individuals. Factors affecting population size and distribution are unknown or unsubstantiated.
Population trend in Australia over the past 50 years: Population size stable or suspected to be stable or increasing.
Knowledge of population trend in Australia: Nation-wide monitoring, but not with statistical sensitivity.
Population concentration: Majority concentrates at 5 or fewer 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 >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: < 100 km².
Distribution trend: Area occupied is stable or has increased. (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.
