Before the aborigines arrived, Australia was almost totally forested, mostly with dry sclerophyll which is a low rainfall habitat, and the amazing megafauna, huge wombats, ‘roos, flightless birds, lions etc, which have all gone due to the land clearances 50,000 years ago, and 80% of the forest has gone too, converted to desert. Now that there is no forest, there is no rainfall. If Musky reckons he could colonise Mars, he could do a dry run in reforesting Australia first.
Everybody has to acknowledge the aborigines as the original custodians of the land at official functions, school performances, sports matches, music concerts and so on, so information about their destruction of the country (fine custodial action) is suppressed as much as possible.
Now with introduced species like lantana the burns can be a different character – lantana burns very hot, compared to grass, and a lantana fire can melt the insulation on underground cables. Such heat obviously adversely affects the biome of the subsoil so that recovery is much longer for the undergrowth which is bad for the remaining fauna. This makes it all the more important to do controlled burns regularly, but in some states like Victoria and South Australia the greenies prevent it.
{edit} the gum trees don’t die in the fires, they spring back into life once the fire has passed. But the eucalyptus oil that vaporises from them in severe heat waves is highly imflammable, and fires can jump half a mile in one go as the oil vapour combusts. In these instances fire breaks are useless.
