Litoria nyakalensis (Mountain Mistfrog) is a moderate sized, robust treefrog 30 – 48 mm snoutto-vent length. It is a uniform olive-brown or grey-brown on the back, sometimes with irregular darker olive markings. The skin is smooth above, with scattered tubercles on the head and back. The belly is granular, cream in colour with a reddish-pink flush on the limbs and pectoral region, and sometimes dotted or flecked with brown. The finger and toe disks are large and conspicuous. The fingers have slight webbing, and the toes are fully webbed. The forearm is robust in the male, with a large nuptial pad with coarse spinules. The tympanum (ear disc) is small and indistinct, and more or less covered by skin. The male mating call has been described as a regularly repeated, rasping, single note call, or a soft, slow, popping grow.

In December 2013 yellow crazy ants were also detected in the Kuranda area (WTMA 2016). 2.2 Feral Pigs (Sus Suspected Feral Pigs are responsible for riparian habitat scrofa) damage and potentially cause adult frog mortality (Richards et al. 1993). 3.0 Climate change 3.1 Temperature Known Climate change is predicted to result in increase; potential increased rainfall across northern Australia extreme (Haylock Nicholls 2000).
Changes in hydrology and other effects of climate change (e.g. reduction in food supply) may also alter the susceptibility of frogs to the chytrid fungus; but these impacts are likely to be variable among species and sites (DoEE 2016).
Improve understanding of how climate change will likely impact the Mountain Mistfrog due to altered temperatures; rainfall; environmental stressors and diseases.
This may alter the weather events hydrology and breeding frequency of stream e.g. cyclones; dwelling frogs; and make them vulnerable to droughts being dislodged in high flows.
