What's growling in the wetland?

Full Day
Book Program
Year Levels


Wetlands are among the most productive and diverse ecological systems on earth. They support an enormous variety of plants and animals including frogs, water birds, insects, crustaceans and invertebrates. Many vulnerable species such as the growling grass frog Litoria raniformis are only found in wetlands. Three quarters of Victoria’s 34 species of frogs use wetlands. An important function of wetlands is their ability to remove nutrients from stormwater runoff to improve water quality. Wetland plants are able to absorb dissolved nutrients, fine particles attach to plant stems while large particles sink to the bottom.

Key Learning Question
