belongs in "before 1900", but I've always wanted to see surviving aurochs. Moa and any of the North American megafauna would be neat, but wildly improbable.
The Moa were killed off long before anyone cared about conservation. The Maori used to burn brush to drive the Moa into the lowlands where they could kill them. In turn, this caused the massive Haast's eagle to go extinct, which was the biggest bird of prey in the world. Saving the moa would mean stopping the Polynesians from reaching NZ.
Well at least as far as New Guinea is concerned they would be outside their historic range. Big Cats never got across the gap from the Indonesian Archipelago to New Guinea. You’d be introducing a very large predator into an environment where none of the species have evolved to cope with it.
Rather like introducing foxes and cats to Australia, or better yet; Cane Toads.
Indeed. Introducing something like a tiger into New Guinea would be distastrous for the local fauna. Stoats, something so small, decimated the kiwi population in NZ for a long time, imagine what a tiger could do in New Guinea.
There weren't tigers on Borneo historically either, so that's probably not a good idea either. Anyway, if they're willing to move a population of an endangered big cat, why can't they put the effort into conserving it on its own island?
