South Australians are encouraged to record frog calls and sightings from their phones at creeks, parks and backyards between June 1-8 to help better understand the population and the distribution across the state.

Green Adelaide and the Murraylands and Riverland Landscape Board are partnering on the FrogWatch Seasonal Census to encourage citizen science and gather frog data in the first week of every season – starting with this winter.

Amphibians are the world’s most endangered group of animals. More than 41 per cent of the world’s amphibian species are currently threatened with extinction. Data like frog call recordings are crucial to monitoring their population.

Green Adelaide Board Presiding Member Professor Chris Daniels encourages everyone interested to take part in the census and get involved in citizen science.

"Frogs are a vital part of many of our ecosystems. They're a natural pest controller by eating insects, and an important food source for their predators," Chris said.

"They're also a great indicator of ecosystems. They're sensitive to pollution, so if we find their numbers decreasing in an area, it's a sign that the whole ecosystem is in trouble."

Chris said that you don't have to be an expert to contribute to science.

"Anyone with a smart phone or computer can record frog calls via the FrogSpotter smartphone app or FrogWatch SA website," he said.

"You'll be helping us understand how frogs and their ecosystems are tracking."

Data will be analysed by experts to monitor frog populations and health. Uploads to the FrogSpotter app or website are added to state and national databases to be used by scientists, ecologists and conservation experts. FrogWatch SA will share the amount of frog calls achieved and interesting findings they gain from the data.
