Tasmania is home to eleven kinds of frog, from the gorgeous green and gold frog — the largest — to the musical banjo frog with its distinctive ‘plunk-plunk’ call.
All Australian frogs are creatures of Gondwanaland, the vast ancient continent which split into Australia and South America millions of years ago and they are quite distinct from their European relatives.
In recent times frog numbers have fallen sharply. Scientists put this down to pollution — frogs are extremely sensitive to many chemicals — and to the destruction of their habitat by human activity.
Now, another enemy in the shape of a fungal disease threatens frogs all over Australia and it has recently been found in Tasmania.
