A recent study shows that the population of Cane Toads in Darwin is surging, despite all efforts to eradicate the animal.
The cane toad was introduced to Australia in the 1930’s from Central and South America to control the beetles infecting the sugar canes. However, the toads were useless for the sugar canes – the beetles were not part of their diet and they were too big (adults can reach two pounds) to reach them in the tops of the canes!
Since their introduction, the toads have multiplied profusely (each female will lay two clutches per year, each averaging 30,000 eggs) and have no predators. They have been detrimental to the ecosystems and biodiversity in the Northern Territory and are considered by many to be the worst ecological disaster in the history of Australia.
