Only time will tell Pike, there is already a small Bandicoot that has had entire localised populations wiped out through out the north.
Reptiles will be next.
Frilled Necks wont be the 1st to go, that will more than likly be the Mertains Water Monitor.
There is no defence to hunger, a hungry animal eats a small toad and its dead.
There is no 2nd chance, no learning curve for our natives, just death.
Due to the way the enviroment is going (weather, climate ect)
In 10 to 15 years Toad numbers will explode and our wild life will become rare, rarer, gone.
Last time I was up the Cape, myself and a friend culled over 2000 toads (including toadlets) over a 3 day period.
In that area, we didnt see any live native reptiles (apart from skinks)
We did see quite a few Dead Dragons, and 2 dead Monitors (1 was fresh and looked in perfect condition, apart from not breathing).
That was just one small pocket of the Cape (Pandanus Park) but that pocket will only spread.
