Green and Gold Frog

Litoria raniformis is a large, robust ground-dwelling frog distinguished by bright green blotching over a bronze or gold background, with a rough, warty dorsal texture and prominent parotoid glands. Adults can reach lengths of up to around 100 millimetres, making them one of the larger frog species within their range. They are largely nocturnal, foraging on insects and other invertebrates, and their tadpoles, along with adults, contribute to freshwater food webs as both predator and prey.

Breeding occurs in still or slow-moving water bodies, where males produce a distinctive low-pitched call.

The species is found in southeastern Australia, including Tasmania, and has an introduced population in New Zealand. It occupies permanent and ephemeral wetlands, ponds, lagoons, irrigation channels, and dams, including artificial aquatic habitats created through agricultural and urban water management, as well as some semi-arid and desert-margin regions.

Populations are declining due to habitat loss from urban and industrial development, agricultural land conversion, and road construction. Water management practices, including altered flow regimes and dam operations, have degraded breeding habitat, compounded by drought and flooding events. The introduced fungal pathogen causing chytridiomycosis has significantly affected populations, alongside predation and competition from invasive species such as fish and other frogs.

Pollution and logging-related habitat disturbance add further pressure.

Conservation efforts include habitat restoration and wetland management programs, captive breeding and reintroduction initiatives, disease monitoring, and legal protections under Australian state and national legislation. Research into chytrid resistance and habitat connectivity continues.

Despite these measures, the species' population trend remains decreasing, and it continues to face compounding pressures from habitat modification, disease, and climatic variability across much of its range.
