Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Amphibia Anura Hylidae

Scientific Name: Litoria subglandulosa
Species Authority: Tyler and Anstis, 1983

Taxonomic Notes: Litoria daviesae, a newly described species, was recently separated from L. subglandulosa by Mahony et al. (2001).

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(i,ii,iii)+2ab(i,ii,iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Annotations:
Needs updating
Assessor(s): Jean-Marc Hero, Harry Hines, John Clarke, Peter Robertson
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification:
Listed as Vulnerable because its Extent of Occurrence is probably less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in its area of occupancy, and in the extent and quality of its riparian habitat.

Geographic Range [top]

Range Description:This Australian endemic occurs on the eastern escarpment of the Great Dividing Range from "The Flags" near Walcha, New South Wales, in the south, to Girraween National Park, Queensland, in the north (Mahoney et al. 2001). It occurs at altitudes above 600m, and possibly up to 1,400m asl.

Population [top]

Population:It appears that this species underwent historical declines. However, most populations were discovered from 1990 onwards and so little historical basis exists for assessing the level of these declines. Noticeable declines have been recorded in three populations on the coast of northern New South Wales. It is now absent from some sites, but the status of populations at other sites is not well known.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species lives near slow-flowing and small streams in dry and wet sclerophyll forest, rainforest, montane forest and heath land. It is also found in semi-cleared grazing lands. It breeds in spring and tadpoles have tentacles around their mouths (rather than a horny beak).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The removal of riparian vegetation, especially by grazing and timber harvesting, is a major threat. Pollution of streams by agricultural and domestic by-products is a threat to this riparian species. Trout have also been released into streams that support small populations of the frog.

Conservation Actions [top]

Conservation Actions: The range of the species includes several protected areas.
