If the Dire Wolves would probably be easier, having so much DNA in common with a modern wolf, it would just be a matter of supersizing them by cloning-especially if they are already able to live in places like Utah-and canines adapt to new places pretty easily, too. Wooly mammoths would need a lot more room, so a big place would have to be set aside for them.
If the clones happened to be more like an ancient mammoth that needs the cold, plenty of hair, etc then fine-there is plenty of tundra with vegetation in Canada and Alaska that isn’t in use-but if they end up being like a modern elephant-no/little hair, likes warm places like Africa and India-then I would think that would be more of a problem-I doubt that the game preserves/sanctuaries in those two countries need any more elephants...
Precisely!
