From what I've read of "cultural cool burns", it seems the part played by Aborigines' fire-stick habits is overstated WRT reducing bushfires. They did it largely to muster animals for food. (They are the ones who've been lighting fires in Australia for thousands of years.)
And the fire chiefs are downplaying the usefulness of undergrowth burns, saying some of the hottest fires burnt through areas cool-burnt a few years prior.
I know its felt that burning off is vital to keeping the bush safe. But I didn't enjoy seeing burnt trees and grass, and smoky fires, when I toured through Kakadu National Park. And they do it too often. The life cycle of some species of grasses that native animals depend on, is longer than the burning cycle they use.
I will admit to being a spelling and grammar nazi, but the 'lose' vs 'loose' thing really bugs me. Language is fluid. If enough people balls it up, the change gets into common use, then the next thing you know, official dictionary definitions adjust to follow.
Sorry, I was determined to stay out of this thread, now I'm sending it all over the place.
