Rocket science it certainly is not.
A friend who is a vet spent many months during her university years studying the possible effects of Moa in the NZ bush, specifically around Fiordland. Back in the 1980's she explained how this concept we have about "pristine native bush" is quite wrong and that with Moa capable of browsing at least as high as a deer (if not higher) the bush would have been similar to what it is today. Clearly deer have simply taken taken the place of Moa and if kept in balance should be no more or less detrimental to the New Zealand bush.... despite what the tree-huggers will try and tell you. For all we know this might also hold true for alpine animals like the Chamois and Tahr as well because there must have been some Moa capable of living in that environment. I bet the greenies would have kittens if somebody pointed out that we need the Chamois and Tahr to help with the propagation of alpine plants.
Maybe we need to pay more attention to these topics and research the possibilities. That would make Ms Sage cough.
