Distribution and Habitat
Population and Distribution
Litoria raniformis was distributed across a large area of s.e. Aust., including Tas., from 0 to 1300 m in altitude (Osborne et al. 1996). The area of occurrence of the species is about 45,000 (map in Mahony 1999). In NSW and the ACT the range of the species was centred on the Murray and Murrumbidgee R. valleys and their tributaries. The species occurred throughout the Southern Tablelands and was also recorded on the Central Tablelands as far n. as Bathurst (Ehmann & White 1997). The species was widespread across Vic. being only absent from the w. desert regions and the e. alpine regions (Littlejohn 1963, 1982; Hero et al. 1991). In SA the species is known to occur along the lower Murray R. valley, the lower s.e. to near Keith, and a small, apparently introduced population, in the Adelaide Hills (Tyler 1978). In Tas., the species occurred broadly across the n. and e. of the island and on the Bass Strait Is. (Brook 1979). (Mahony 1999)
Declines have occurred in sections of the species range (Mahony 1999). Ehmann and White (1997) noted that in NSW the species had disappeared from sites in the central and southern highlands. The disappearance of populations from the Southern Tablelands of NSW/ACT has been reviewed by Osborne et al. (1996). It is currently widespread throughout the Murray R. valley but has disappeared from a number of sites along the Murrumbidgee R. (Mahony 1999) and there are no recent records from the Monaro district near the Vic. border (G. Gillepie pers. comm.). The species has disappeared from most of its former range across Vic. (G. Gillepie pers. comm.). Litoria raniformis persists in isolated populations in the greater Melbourne area, and in the s.w. of the Vic.. Isolated populations are known from a few sites in central Vic. and Gippsland (Victorian Wildlife Atlas).
Litoria raniformis is known from Cocoparra, Willandra, Grampians, Wilsons Prominatory, Asbestos Range, Mt William, Maria Is., and Freycinet NP, Sale Common State Game Reserve, Ewings Marsh Flora Reserve, Westgate Park, Nooramanga Coastal Park, Waterhouse Protected Area, Tamar R. Wildlife Sanctuary, Bool Lagoon, Messent NR, St Helens Point State Recreation Area, Woomargama and Bondi SF (Tyler 1997). The species is also known from farm areas throughout its range, disused council landfill sites in Melbourne and Woodstock Lagoon Conservation Area (Tyler 1997).Habitat
Litoria raniformis is usually found in association with dams, ponds and marshes, either amongst sedges and other semi-aquatic vegetation, or sheltering under logs and rocks (Gillespie et al. 1995). The species appears to be associated with permanent waterbodies though it is unclear whether, like L. aurea, the species also utilises ephemeral pools (Mahony 1999). The species occurs both in woodland and areas of improved pasture (Gillespie et al. 1995).
