Their hardy nature and voracious appetite, initially an attractive quality to farmers, led them to become prolific invaders. They completely failed at regulating the cane beetles, and instead turned their attention to other native insects. Since the initial release of 3, toads, cane toad populations in Australia number in the millions and their range continues to expand. Why are they harmful?
The management of cane toads in national parks and on other land tenure is guided by the Saving our Species SoS program. Comprehensive best practice guidelines for the removal of cane toads from our national parks are found in Eradicating cane toads in NSW outside their current range of distribution.
Currently, there is no broad-scale control method or biological control agent for the effective widespread reduction of cane toads that would not harm native species. Cane toads must be collected and removed by hand.
Traps and barrier fencing can be used to contain them but vary in effectiveness. According to recent research by the University of Sydney, refrigeration followed by freezing is the most efficient, effective and humane method of cane toad euthanasia.

Our study can reveal that the cane toad invasion has exposed previously unknown trophic links, thereby underscoring our ignorance of the complex interactions in animal communities.
To demonstrate further effects through the food chain would require a larger and longer study, but Clulow says the higher number of birds could affect plants that the birds feed on, as well as other animals that eat those plants and so on.
