This Australian endemic occurs along the coast and in adjacent areas of New South Wales (from the Wollondilly River northwards) and southeastern Queensland (north to the Connondale Ranges, with an isolated population further north in Kroombit Tops) (Donnellan et al. 1999).
Habitat and Ecology
The species inhabits rocky and mountain streams in rainforest and wet and dry forest including swamps. It is often found on shrubs and low vegetation beside creeks and streamside ponds, seldom in still water. It breeds in summer and spring. Males call from rocky riverbanks or streamside vegetation. Eggs are attached to submerged vegetation in streams and ponds. Larvae take 12 weeks to metamorphose.
It is a common species.
In the past logging in forest was a threat. Development and clearing of wet sclerophyll forest and drainage of swamps are now more serious threats. It is probably also impacted by introduced fish, notably trout. Chytridiomycosis has been confirmed in this species by PCR testing. There has been extensive monitoring across the distribution and significant declines have been noted in high altitude populations, some of which have disappeared. However, there is also a recorded recovery of population numbers in one closely monitored population of this species, and overall it remains abundant in many places and is not significantly threatened.
The range of the species includes several protected areas.
We follow Donnellan et al. (1999) and Mahony et al. (2001) in treating Litoria nudidigita as a species distinct from L. phyllochroa. Donnellan et al. (1999) show that even after the removal of L. nudidigita, L. phyllochroa comprises a number of lineages which might constitute separate species. We follow the convention that Litoria barringtonensis is a synonym of L. phyllochroa, although this has been questioned by Donnellan et al. (1999).
