Being a forester I have some experience and knowledge of bushfires. It
appears to me that the greens/extreme environmentalists are now practicing an ecological version of Terra Nullius, they just seem to ignore the fact that this land has been managed by humans for over 40 000 years. Deliberate burning in the cooler months will greatly reduce the loss of life, property, wildlife, and protect water quality - no doubt about it. We have had problems with wildfire ever since we removed the aboriginal peoples.
This is an important point. The aborigines significantly altered the natural environment in Australia by their slash and burn techniques.
The result was that the predominantly Casuarina vegetation gave way to a predominance of Eucalypt forest. The Eucalypt will regenrate after bushfires, whereas casuarina tends to die out. That's one of the reasons that we see so many Casuarina spp. in wetlands or fire resistant areas of Northern Australia.
Given that the ecosystem has been modified, it becomes essential to continue burning the forest, although the frequency of burning should not be too great or it reduces biodiversity and increases the risk of a severe canopy fire at some stage in the future due to excessive growth in the canopy (the canopy should be allowed to burn at intervals. If you have burnoffs too often, that won't happen)
The Wilderness society 6 point plan recognises the above points and others. It might seem like a good idea to have more frequent burnoffs, but the overall result for wildlife
and society will be worse.
By the way, I have been a specialist advisor to the Queensland Fire and Rescue Service since 1992, and I have organised a number of exercises and have been using the AIIMS framework since it first came out. I'm also an advisor to our local Counter Disaster committee. So I can see the strategic picture from both the Fire Service and the Environmental point of view.
I also live in the bush most of the time, so I know what I'm talking about. I've see what happens when a bushfire meets a hill. You need to see it to understand how quickly it can happen. It makes the hairs on your neck stand up (and you tend to come out with some colourful expletives). It's all too easy to be caught in that kind of situation.
