Blow on a fire, it roars into life, even though your breath contains less oxygen than normal air. The Fire Triangle comes in various versions, but OXYGEN is always there. Black Saturday made it obvious that gale force wind increases oxygen supply to the fire and pushes FFDI and GFDI off the scale. World-renowned fire scientist Kevin Tolhurst has told the Royal Commission that in these conditions a crowning fire will not be stopped by any amount of fuel reduction save concreting the Victorian landscape, especially all farming pastures, where fire runs fastest. DSE's Kimberly Dripps told the Royal Commission Tuesday that 70 per cent of Victoria has already been cleared since the white fella arrived and that native eco-systems have important VALUES. The only problem for the fuel reduction lobbyists is that they do not acknowledge those values because they are not in a position, representing their commercial backers, to make a buck out of the landscape. Peer reviewed science can inform us how to apply low intensity small-scale mosaic fuel reduction burns to SOME Victorian bioregions to keep these eco-systems healthy. Human life depends on eco-system health.
