 By 2010 cane toads "(Bufo marinus)" started appearing around the outside region of the park but in lower numbers than at the nearby Borders Ranges NP.The cane toad is highly poisonous at every stage of its life, from egg to fully grown, and any animal that tries to eat it would likely die.Cane toads also prey upon and outcompete native endangered frogs for vital spawning habitats.
