THE Sunshine Coast is home to about 40 species of native frog, but disease, urban development and habitat loss mean many species are declining in number.
Queensland Frog Society president Dan Ferguson said that while some common backyard frog species were on the increase, many lesser-known species were struggling.
"There are a lot of reasons why frog numbers can be declining," Mr Ferguson said.
"Loss of habitat, diseases or pathogens, it depends on the species."
About 30 years ago, the chytrid fungus, which stops frogs from breathing through their skin, was introduced.
Populations of the creatures have been declining since.
But as the warm, wet weather of the Sunshine Coast is ideal for frog breeding, many species are remaining strong.
Mooloolah River Waterwatch and Landcare Inc manager Jan Kesby monitors the nine differing frog populations in the Mooloolah River and Mountain Creek areas.
"The Giant Marsh frog, that's an endangered frog, it's populating really well," Ms Kesby said.
As coastal areas such as the Sunshine Coast are most susceptible to habitat loss and degradation, Ms Kesby urges people to take care when doing anything around our natural waterways.
"Frogs can show us how clean the water is," she said.
"They're very sensitive to pollution and keep the bugs at bay."
Pollution from urban areas, pesticides, exotic weeds and changes in water PH levels are common causes of population decline. And our arch enemy, cane toads, haven't helped either.
"Tadpoles certainly compete in water bodies and adults compete for food," Mr Ferguson said of the toad/frog rivalry.
"Adult cane toads will eat frog tadpoles.
"It is an added pressure."
About 15 endangered frog species live in Queensland.
Frog friend Mr Ferguson, who has been researching frogs for the past 14 years, said many people had the wrong idea about the amphibian.
"A lot of people don't like frogs," he said.
"They think they're all slimy and gooey.
"They're just a misunderstood group."
And it's not too late to hop into action to help protect Kermit and his friends.
The Queensland Frog Society has an army of workers, including four honorary life members, who help raise awareness through education, camps and workshops.
Ms Kesby, who has been working with frogs for 15 years, hosts "Frog Workshops" with MRWL to teach people how to identify different frog species.
The next workshop is due to be held in November.
To help in the fight for frogs, residents can install a pond, make their backyard more "frog friendly" and keep waterways clean.
