Population Monitoring

Researchers have undertaken annual monitoring of the Southern Corroboree Frog population for many years.

The most reliable monitoring technique is to survey the number of breeding males.  The breeding males reliably respond with their threat call when researchers shout near their sphagnum nests and the calls can be easily counted.  In 2009, the first Corroboree Frog eggs were reintroduced back into the wild. The frogs that survived from these eggs became sexually mature and started being recorded as breeding males in 2012.

The graph shows the number of Southern Corroboree Frog males recorded in annual surveys from 2003- 2016.
