The spread of the toad
Cane toads were introduced into Australia in 1935 in an attempt to control pest beetles in the sugar cane industry. They were unsuccessful in their control efforts, but very successful at invading the ecosystems of Australia’s north. Cane toads were originally released in Gordonvale in Queensland, but have spread west and south to now cover 1/3 of Australia.
Ecologists warn that, unless stopped, cane toads will colonise Perth. They may even infest areas as far south as Margaret River and Esperance.
