Hop into the Frog Census today

Growling grass frog

Grab your smartphone and join nearly 600 volunteers in the Frog Census monitoring program, helping Melbourne Water monitor the health of Melbourne’s waterways and frog populations.

There is no expertise required. It is as simple as downloading the app to your smartphone and recording frog calls at waterways such as rivers, creeks and wetlands.

Your recordings will support water quality monitoring with frogs, and add to a dataset of over 5,000 recordings collected since the project launched 16 years ago.

Melbourne Water also recently announced that a milestone 1,000 recordings have been submitted through the app since its launch last year. 

Melbourne Water uses frogs as indicators of waterway health because eggs and tadpoles – as well as frogs’ sensitive, permeable adult skin – need good quality water to stay healthy.

Recordings can also show whether habitat rehabilitation or destruction is affecting frog populations.

The data is also added to CSIRO's Atlas of Living Australia and Victorian Biodiversity Atlas, to share knowledge about endangered species and biodiversity.

Melbourne Water is calling for data in August, October and November, but welcomes submissions all year round.

If you do not have access to a smartphone but would like to submit a recording, head to Melbourne Water website for instructions and download their data sheet.

The app can be downloaded from the iTunes store or Google Play. For more information on events in your local area or instructions to create a frog friendly garden, contact Melbourne Water.
