Interesting section from a book called "Back from the Brink" by Peter Andrews:
"sixty thousand years ago just before aborigines arrived,Australia had a forest mix very different from todays. One third of the trees were palms,one third conifers & the other third consisted of a variety of tree types,only one of which was eucalypts. It was an extreemly biodiverse landscape. Burning by Aborigines reduced the biodiversity to a fraction of what it had been. European settlers reduced it again. The result gum trees make up 90% of Australia's forest mix. Or to put it more plainly, 9 out of every 10 trees growing in Australia today are gum trees."
So through mans interference we now have a virtual monoculture of the best ,oil rich,fuel producing plant kown to mankind & we used to manage it quite well till the Greens pressured us into reduction of hazard reduction. Adam Bandt & his like might want to consider the trade off between a series of low intensity cool burns that may kill the odd dopey koala or the firestorms we have created that can wipe out entire communities of native wildlife.
