Ecology

"Litoria castanea" is a member of the Litoria aurea complex, being distinguished by cream markings on its thighs. The overall colour is pale green and the dark to black spots are highlighted by the bronze patches. The toes are entirely webbed, the species favouring permanent water bodies. The reasons behind its drastic decline are unclear, but the disease chytridiomycosis is suspected to have played a major role.[1] No recorded sighting had been made since 1980, and the species was believed to be extinct.[1] However, in late 2009 New South Wales Fisheries field scientist Luke Pearce located a surviving population of the frogs.[3] Scientists acted quickly to establish a small "insurance" colony. Soon after, the wild colony was eradicated due to two consecutive floods and an outbreak of chytrid fungus. Following a breeding program at Sydney's Taronga Zoo, in early 2018 a colony of yellow-spotted bell frogs were released in a secret location in the New South Wales southern tablelands.[4]
