Wait what? That doesn't make sense, they were introduced, they can't become native through those means. They are however, naturalized, as they don't harm the native ecosystems there.They're native now - it's why I called them Hawaiian Auratas elsewhere.
Yes I realize they have evolved to be different (slightly) but that still means naturalized. It's like Dingo's in Australia, they replaced the Thylacine as the top predator and are now naturalized. They however, should be protected because removing them would harm the ecosystems there more by removing the only large terrestrial predator. The auratus on the other hand could be removed or could stay with no ill affect.The frogs have been on the island for over 30 years and they are now considered a distinct aura tues morph, that is the reason.
