Yeah mate those toads are creating havoc amongst the species that didnt evolve with them but we only need to think of when they were released in Qld (30`s?) much the same thing happened with snakes,goannas etc snuffing it but they have got over it now,so too will the top end species,the good old aussie black crow now has learnt to tip road kill toads over and eat them thru their stomach thus escaping the poison glands on their backs...matter of adapt or die eh!
