to bad they are a endangered species in victoria and have a scattered distribution. Im going to a place called Cowies Creek (site 5) as populations of Southern Bell Frog have been located here 2009-2010 and 4 other frog species have been discovered around this area. The Site is considered high quality habitat for southern bell frogs, striped marsh frogs, common froglet, spotted marsh frog and brown tree frog

Prior to last Christmas (2009)a green frog arrived in my outdoor fish pond. No idea where it came from. I'm sure its a Growling Grass Frog but I've never heard it "crock". It has grown to about 90mm, then the other day (Oct 2010) a smaller frog (about 50mm) arrived. Hopefully next year I'll have a few more in my pond. The Green Growling Grass frog lives well in Portarlington, Victoria.

I have built a pond in Narracan Victoria and to my delight 4 Growling Grass frogs have moved in to make it there home. I noticed the huge tadpoles last year. There are also a couple of Banjo frogs living there as well.

how did the growling grass frog get to their habitat in the first place.

Angela - according to the Department of Sustainability, Environment, Water, Population and Communities, this particular frog is a very mobile species and can cover 1 kilometre in 24 hours; so this mobility accounts for how this species gets to its preferred habitats. See the following for more information:

I live in N.TAS on the Tamar River, There are at least 2 G & G's in my garden. One NOW sitting on the edge of an old bath with water and tadpoles in it and the other round the corner in an old cement wash trough. I'm hoping there will be some frogspawn soon.

I have been studying the Growling Grass Frog for 2 months so I have pretty much memorised all the facts about this Hylidae. And to be honest this is a great website but it needs more informatio.

I found a Growling Grass frog in my back garden in Portarlington, Vic. I have contacted Andrew from DSE for advice on what to do with it. I am just awaiting his call back.

Pretty sure we had a Growling Grass Frog in amongst the reeds in our dam last November, in St Andrews - we only heard it. We haven't heard it since the weather has become hot and dry. Hoping it will return or represent itself! Can they be identified by the growl only, are they found in our area and if it was a GGF what are the chances of it coming back to our dam?
Brendan Casey 22 March, 2013 15:29
Listen for the 'plonk' noise as they jump into the water. The sound is quite distinctive and indicates a GGF.

We live 10k east of Daylesford on a five acre property with two dams. Last year we discovered we had a growling grass frog residing in the larger of our dams. My wife has viewed the frog on a number of occasions, sitting in a yabby hole on an island in the middle of the dam. Two days ago we heard the frog growling, so it appears the frog has returned again this year.

Had about 6 Growling grass frogs on Milfoil on 1 meg dam at Rokewood Junction, in June started to fill dam and they went wild. Now have about 200 young growlers on dam along with stripped marsh frogs and banjo's

I grew up in Reservoir in the sixties and as a child these frogs lived in every drain, gutter and waterway. I was saddened to hear they are disappearing from much of their range. They are such a large and beautiful creature that were everywhere in mid sixties suburbia. Back then not every road was tared and not every drain was cemented in. Maybe this progress has helped lead to it's demise.

We live in south Kyneton. Our dam has filled for the first time in 7 years. I am sure I heard the call of the growling frog for the first time this week. Hopefully I will be able to see it one day.

Have a frog pond in Geelong habitat garden with Banjo frogs. This year heard a Growling frog for first time in my pond. Hope they can cohabitate.

Hi Christiane, great to hear you have Growling Grass Frogs. Hopefully any other species of frog you have are nice and agile as the Growling Grass Frogs will prey on other frog species. Fingers crossed there is room for all.

I have two of these frogs in my pond. Not sure if they are Growling frogs or Green & Golden Bell frogs. They can change to a very dark brown when they sit on dark wet rocks. and in the sun they go a really nice bright green. Can anyone help me to work out if they are male or female. thanks

Hi Cat,

According to A Review of the Biology of the Southern Bell Frog Litoria raniformis (Anura: Hylidae) by Graham H. Pyke from the Frog Ecology and Behaviour Group at The Australian Museum;

“Adult males can be distinguished from females on the basis of ‘nuptial pads’ or ‘rugosities’ on the first digit or ‘thumbs’ of their front limbs.  These pads are recognisably distinct from the rest of the digit as raised areas that vary from a very dark brown during the breeding season to a pale colour similar to that of the rest of the digit during the remainder of the year. Adult males also generally have darkly mottled throats while females have relatively clear off-white throats.”

We have sg frogs in the SEWater decommissioned dam here in Kunyung Rd Mt Eliza and this statuary authority wants to sell it off for housing thus killing off the remaining frog population

There are a number of Growling Grass Frogs (saw and photographed about eight) at the PEGS sports ground, Keilor Park. We have seen a population spike since the Conservation Club built a pond to provide breeding habitat.

Does anyone know how many of them are left?
