Distribution and Habitat
Population and Distribution
Taudactylus acutirostris was widely distributed from Mt Graham to the Big Tableland, n. Qld, at altitudes of 300 to 1300 m (McDonald 1992). The area of occurrence of the species was about less than 9,000km2 (Hero et al. in press). A conspicuous inhabitant of upland rainforest streams because of its diurnal habits and former abundance, the species started disappearing in the s. part of its range in 1988 and had disappeared from s. of the Daintree R. by 1992 (Richards et al. 1993). In the past the species was considered locally abundant and in 1989, 48 calling males were recorded along a 100 m stream transect (Richards et al. 1993). When surveys of the site were undertaken in 1990, only one adult and several tadpoles were located (Richards et al. 1993). The decline of this species is well documented and, in approximately five years from 1988 to 1993, it disappeared from an area spanning about 2o30’ latitude (Ingram 1993). Sightings of a single individual in a small tributary of the South Johnstone R. in 1996 (Marshall 1998), and in 1997, a gravid female seen near Mt Hartley (Hero et al. 1998), are the only records of the species since 1994 (Hero et al. in press).
Taudactylus acutirostris was formerly known from Lumholtz, Wooroonooran, Daintree, Crater, Cedar Bay, and Tully Falls NP, Timber Reserve (165 Monkhouse), Lamb Range, Malbon Thompson Range, Herberton Range, Ravenshoe, Kirrama Range, Mt Fisher, Maalan, Mt Lewis, and Windsor SF, SF (757 Japoon) (Tyler 1997).
Taudactylus acutirostris was a habitat specialist, endemic to the W.T. Bioregion (Williams & Hero 1998; 2001) occuring along small creeks in rainforest and wet sclerophyll forest above 300 m (Liem & Hosmer 1973). The species was seen on the rocks during the day near swift-flowing streams or in the rainforest leaf litter during wet weather (McDonald 1992).
