Background

Frogs belong to the group of animals called amphibians. They are unique in their ability to live on both land and in water, and to metamorphose during their life cycle. Frogs can breathe through their moist skin and through their lungs. Australia has a fascinating and spectacular variety of frogs, over 210 of the world’s ~5,000 species. In 2011 a population of Bleating Tree Frogs Litoria dentata was discovered in East Gippsland, a new species for Victoria. This finding constituted a southerly range extension for the species, which was known along the east coast of Australia from southern Queensland to southern New South Wales.

There are now 38 species of frog known to occur in Victoria, but many have declined or are currently in decline. Many species are classified as endangered, including the Growling Grass Frog, which was once common around parts of Melbourne. There are many reasons for the decline in numbers including habitat loss, introduced species, pollution and diseases. Students can assist in the conservation process by being involved in frog surveys and creating suitable habitat to allow local frogs to naturally colonize an area.

The Growling Grass Frog was discovered in the Ecolinc wetland in 2007.
