Southern corroboree frog

Pseudophryne corroboree
Critically Endangered: Biodiversity Conservation Act 2016; Environment Protection and Biodiversity Conservation Act 1999; IUCN RedList (IUCN 2018)


The southern corroboree frog is a tiny (2-3cm), distinctive frog with bright yellow and black stripes running along its back. On its belly, it has black, yellow and white blotches. Its call is a short “squelch”.

This species only exists within Kosciuszko National Park and depends on small, still ponds and sphagnum bogs to breed and lay eggs. Males call for a mate from covered depressions or mossy chambers at pool edges. Tadpoles overwinter in the pools where they feed and grow to emerge in early summer. They do not reach sexual maturity until they are about four years old.

Feral horse damage to breeding sites has been identified as a major threat to the survival of the southern corroboree frog. An examination of 78 sphagnum bogs found that bogs in the most degraded conditions were those occupied by horses.

This species is at very high risk of extinction because of their tiny population and the damage being done to their breeding habitat. Each individual takes four years to reach sexual maturity, making population resilience very low following severe disturbance.

Active management of feral horses is necessary to reduce negative impacts on this critically endangered frog, and to allow native habitat to recover. Only then will the southern corroboree frog have the opportunity for recover.
