Frogs

In Australia there are approximately 200 species of  frogs. Frogs are ‘amphibians’. The word amphibian is from the Greek words  for double (amphi) and life (bios), which describes that most amphibians  live in water and on land at some stage of their life.  All Victorian frogs require water at the beginning of their life, during the tadpole stage, whilst adult frogs can be found in a range of habitats. However, the adult frog must live near water, or in regions that have plenty of dew and moisture, because they can die if their thin skin dries out too much. Therefore wetland environments, such as found here at Cussen Park, provide ideal habitats for frogs.

Frogs indicate healthy environments

Frogs serve as good indicators of  the overall health of a wetland. Adult frogs  have thin delicate skins, and their eggs and tadpoles are directly exposed to soil, water and sunlight, which means that frogs are very sensitive to pollution, especially pesticides and herbicides.   Unfortunately worldwide amphibian populations have  been on  the decline since 1970’s, luckily here at Cussen Park frog numbers are still quite high.

Identifying Frogs

There are many different ways of identifying frogs and surveying frog numbers. Hand searching for frogs can destroy their habitat and you may harm them if you handle them incorrectly. This Poster shows pictures of the most common frogs found at Cussen Park , highlighting  distinguishing features that can be easily identified without having to handle the animals unnecessarily. However, it is preferable to identify frogs by listening to their call, because it can be done quickly, accurately and without disturbing the frogs or their environment, thus a simple key to identifying some frogs by their call has been provided.
