Frogs Breed in Record Time at Sydney Zoo

WILD LIFE Sydney Zoo has announced a remarkable conservation success with the first on-site breeding of endangered Littlejohn's Tree Frogs. Arriving at a new, custom-built facility, the frogs produced three clutches of eggs within just 72 hours, a feat previously unachieved in a zoo setting. This achievement is the culmination of over a year of preparation and collaboration with the University of Newcastle's Centre of Conservation Science and Amphibian ICU.

The Littlejohn's Tree Frog, native to the Sydney Basin, faces imminent extinction from climate change, habitat loss, and chytrid disease, resulting in fragmented populations with reduced genetic diversity. The zoo received 58 frogs, including wild founders and sub-adults hatched at the university.

Curatorial Manager Ashley Wombey highlighted the "Frogservation Lab's" meticulously designed life support systems, reflecting the frogs' natural habitat. Dr. Alex Callen from the University of Newcastle noted that this is only the second time the species has been bred in human care, emphasizing the program's focus on improving genetic diversity from isolated regions.

By establishing this breeding colony in Sydney, the zoo aims to create a genetically diverse "insurance population" for potential reintroduction into the wild. While some tadpoles have hatched, the team is closely monitoring remaining eggs, with more anticipated soon. Visitors can learn about this vital project at the zoo.
