Where have all the frogs gone?

Although the Phillip Island Nature Park does fantastic work preserving the unique

wildlife on the island -- especially the penguins and their habitat -- I doubt their wisdom when it comes to the widespread use of herbicides.

Twelve years ago frogs croaked in the water that collected between our home and the mutton bird rockery. Now there are none.

Repeated spraying, aimed at controlling kikuya grass, has killed every last frog.

There are other ways of controlling this nuisance grass. Frogs don't have to be killed in the process.
