I haven't seen that episode, or at least i don't recall seeing it, but whatever habitat was wiped out, i'm sure it wouldn't have been detrimental to the pythons. They have survived there for a very long time, i think it would take something very significant to wipe this species out. Cane Toads could be that, but i would have guessed that gorges would not really be suitable habitat for Cane Toads. Who knows, maybe RSP are able to eat Cane Toads without ill effect. When the invasion comes, RSP numbers will explode and they will take over all of NT and wipe out all the other python species along with the Cane Toads :shock:
