FrogID Week is Australia's Biggest Frog Count, held annually for Australians to help record frog calls through the free FrogID app, as a measurement of frog health and distribution around the nation.

FrogID Week aims to monitor frog distributions over time, helping us to understand how frogs and their ecosystems are responding to a changing planet.

From croaks and barks, to whistles and bleats, every frog species makes a unique sound.

Using the free FrogID app, you can record the frogs calling around you and help us count Australia's frogs.

FrogID Week goes until November 21 2021 and go here to sign up.

Australia has over 240 known species of frog, almost all of which are found nowhere else in the world. Some species are flourishing, like the Striped Marsh Frog. But others have declined dramatically since the 1980s, and four have become extinct.

FrogID is a national citizen science project that is helping us learn more about what is happening to Australia's frogs. All around the country, people are recording frog calls with nothing more than a smartphone.

FrogID relies on frog calls to identify species, as many frog species are indistinguishable by appearance, we want to minimise disturbance to frogs and their habitat, and we want to know about the breeding season and breeding habitats of frogs.

By recording a frog call with the FrogID app, you provide a unique, time-stamped and geo-referenced audio recording that allows scientists to understand and conserve Australia's unique frog species.
