Frog Watch Program

Frog watch is conducted by the City of Greater Dandenong in conjunction with Melbourne Water to monitor the health of local wetlands and waterways. Frogs are identified and their calls recorded at local bushland reserves. This information is then passed back to Melbourne Water to gain a picture of the water quality of Greater Melbourne’s wetlands and waterways.

Frog are an indicator of the overall health of the environment. They breathe through their skin and are dependant on water, so are extremely sensitive to small changes in their habitat. They are an important link in the food chain providing a food source for many animals such as snakes, birds and mammals. They also feed on a large number of insects and invertebrates. They will not live in heavily polluted areas. Nearly 30% of Australia’s frogs are now under threat of extinction. This is due to issues such as loss of habitat, climate change, disease, pollution and predation by feral animals like cats.

About 11 species of frogs occur in the Melbourne region. Frog species commonly found in the City of Greater Dandenong include: Eastern Common Froglet (Crinia signifera), Southern Brown Tree Frog (Litoria ewingi), Striped Marsh Frog (Limnodynastes peroni), Spotted Marsh Frog (Limnodynastes tasmaniensis), and the Eastern Banjo Frog or Pobblebonk (Limnodynastes dumerili).

What can you do to help our precious frogs? Take part in frog watch!

Frog watch is a great way for you to get to know your local waterway and the fauna that call it home, and is also combined with a night stalk to discover some mysterious nocturnal animals such as the elusive Tawny Frogmouth (Podargus strigoides). Frog watch and night stalk activities are run in Autumn and Spring when frogs are breeding.

Other ways of helping to reverse declining frog numbers:

  • Participating in tree planting days
  • Planting local native species in your garden at home, school or workplace
  • Conserve water by taking short showers
  • Reduce chemical use
  • Keep your cat inside at night
