MELBOURNE'S frog numbers may have taken a dive, with unseasonably dry = weather=20 sparking a drop in noise from the city's creeks.

Melbourne Water has encouraged volunteers to record frog calls in = their local=20 areas. Armed with digital recorders, a small army of dedicated "frog = finders"=20 will lurk at local waterholes to seek out vociferous amphibians.

Frog calls are used to map the distribution of frog species across = Melbourne=20 and, ultimately, gauge the health of rivers, creeks and wetlands.

The annual frog census, now in its ninth year, was launched at = Werribee Zoo=20 yesterday as part of World Animal Day.

Melbourne Water's manager of waterways, Chris Chesterfield, said = frogs were a=20 key barometer of environmental health but climate change was taking its=20 toll.

"The first eight months of this year have been the driest on record," = he=20 said. "In the last 12 years, we have had below-average rainfall, which = has=20 resulted in lower flow of our streams and more frequent drying of our=20 wetlands.

"This means the habitat area is reduced and frog numbers = decrease."

But he said he expected frogs to be out in droves after the recent = spring=20 rain.

''We've had very good rain this September and expect more frogs to be = out and=20 about," he said.

He said 16 species thrived in the Melbourne Water region, ranging = from the=20 common froglet to the large growling grass frog. To date, more than 3400 = frog=20 recordings have been submitted to Melbourne=20 Water.
