unfortunately most of the outback of Australia is made to burn.....the plants life cycles revolve around it because the country normally burns with frightening regularity......the arid land eucalyptus groves can be real scary because of all the volatile oil in the dried leaves it takes nothing to get a fire started and have it a raging inferno in a blink of an eye.....
hope you guys down get through the fire season down with as minimal loses as possible.....
This answer is closest to the mark.......
The Flora in Oz has evolved to become receptive to fire. The Aboriginals have been lighting fires for 40,000 years as their nomadic lifestyle moves to new areas and burns the old.
There are many trees that have seed pods so hard, they have evolved so they explode during a bush fire an propagate.
The bush, trees and general flora renews after a fire. I owned an acreage on the outskirts of Sydney that was struck by firs one Christmas and within 3 months, it was clean, beautiful and lush, with green foliage everywhere and all the dried and dead underbrush cleared up and the soil cleared to grow natural grasses. Before the fire, I was foolishly raking and clearing as much underbrush as I could and it was dangerous and tiring work. The fires keep the snakes in check which is a good thing.
Heat "is" Australia, and you don't need a fire. Many many times I went to work when the temperature soared way past the ton, to return to a cremated yard where all the plants were scorched brown and totally dead. This is usually in February.
By cutting off the old foliage, a new lush green replacement is weeks away. This was particularly noted with tree ferns which have trunks a foot thick and grow 15-20 high in the right conditions.
In Oz, it is just the way it is.
