It’s only half way through September, and the grass is still green, but scratch an inch or two below the surface, and the ground is bone dry. Or at least it is in hilly Warrandyte where the rain flows off long before it can properly soak in.
So, I’m worried about the fast approaching bushfire season. East Gippsland is said to be most at risk this year, but the Green Wedge in Nillumbik Shire can’t be too far behind. And we have more people living in the shire:
‘The Nillumbik Shire Estimated Resident Population for 2017 is 64,626, with a population density of 1.50 persons per hectare.’
That’s a lot of people, but when you look at where most of them live, the figures take on a deeper meaning:
The area outlined on the map is the Shire of Nillumbik. If you read the legend to the right of the map, you’ll see that most of our population clusters in the pink and red areas to the south [the pink area circled in orange is my area, North Warrandyte].
An important feature not shown on the map is that much of the southern part of the Shire is intersected by the Yarra River.
The two areas circle in orange represent the two bridges that are the only way of crossing the Yarra from my side of the Shire.
The Offspring and I live on the north side of the Yarra, so we have to cross the Warrandyte bridge to get into Warrandyte Village, and from there to somewhere further south.
That bridge is currently being extended from 2 lanes to 3, but it’s not finished, and access is even worse than normal. Going in the other direction, we have to go through Eltham and cross a second, 2 lane bridge to get south of the river.
Guess which direction the worst bushfires come from! Clever you, yes, the north. Caught between fire and water, lovely.
Now, let’s have a look at the terrain around Nth Warrandyte. This is an aerial view of the area around the bridge:
The blue line is obviously the river. The red bit is the bridge in the middle of the orange bullseye. Up from the bridge is Nth Warrandyte. Down from the bridge is Warrandyte village, a popular tourist spot on weekends.
A feature you can’t see from that aerial photo is the terrain. Up hill and down dale describes it pretty well. The perfect playground for bushfires that love racing up hill.
All that dark green stuff? Gum trees and scrub, all of it native and all of it evolved to burn. My block is relatively open, but further from the main road the blocks are densely treed and the only way in or out is often via dirt roads.
I have every fire protection under the sun. Most of the houses in my area have nothing. Even the pre-school and CFA fire station are nestled in amongst the trees with no in-ground water tanks, roof sprinklers or fire-resistant shutters. The area is a bushfire disaster waiting to happen, and Nillumbik Shire Council has done nothing to mitigate the risk, for years and years and years. If you’re interested, here’s a post from May, 2017 that looks at the Council’s budget for bushfire mitigation. Yup, they really take it seriously…
So, I’m worried, but this year there may just be a bit of hope on the horizon. Two years ago, an organisation called Pro-active Landowners [PALs] became a force to be reckoned with, and the Council elected in 2016…changed.
The following recommendations are taken from a recent PALs submission to Council:
Essentially, PALs is recommending that the bushfire danger in the Shire [which is huge] be managed.
It sounds so simply, yet for decades, Council has done anything but. I don’t know whether the interest group within the Council felt that nothing could be done to manage the risk – i.e. act of god etc. Or they were so determined not to let big, bad developers ‘ruin the green wedge’ that they were happy to see it all burn instead.
Council mitigated nothing while tying the hands of the CFA [the Country Fire Authority is supposed to save us from bushfires]. Worse, Council stopped landowners from protecting themselves either. You have no idea how good it feels to finally have a voice.
If the PALs recommendations bear fruit, we will finally be able to reduce the fuel load in the Shire. Fuel load is the leaf litter, twigs, branches and undergrowth that feeds a bushfire, and Warrandyte has masses of it. But even if every resident of Warrandyte cleaned up religiously, there are great swathes of public land that are virtually untouched because the previous Council wanted to keep things ‘natural’.
The irony is that the Green Wedge is anything but natural.
Pre-settlement, the Aboriginals used to manage the land by doing many, small, cool burns. These cool burns created a patchwork of burnt and unburnt land so that the native fauna had somewhere to escape to. The net result was that the fuel loads never grew too high.
In areas not managed by the Aboriginals, nature itself managed the land with lightning strikes. Lightning would start small bushfires that would run until they finally died out. Again, because these small bushfires happened so regularly, the fuel load did not have a chance to become truly dangerous.
And then the white man came along with his English farming practices. Farmed land had to be protected, so bushfires had to be put out before they could do much damage. The net result was that parts of the land were over managed – i.e. the farms – and great big areas were left completely unmanaged, allowing the fuel loads to grow. The character of the land changed, and the bushfires turned vicious. 1939 was a very bad year, and so was 2009.
2009 was the year in which ‘…173 people tragically lost their lives, 414 were injured, more than a million wild and domesticated animals were lost and 450,000 hectares of land were burned’ in the Black Saturday bushfires.
If you’ve ever built a camp fire, or an open fire in a hearth, you’ll know that fire needs just two things to burn – fuel and oxygen. That’s why you build a teepee of twigs and dry kindling to start the fire. The open structure allows air in to feed the flames. After the fire is going though, the kindling is no longer needed because hot air rises, sucking in cooler air from below.
A bushfire does much the same, and the bigger the fire the more powerful it becomes, preheating the fuel ahead of it so it will burn even faster. The Black Saturday fire was so powerful, it generated its own weather.
No amount of human technology could have stopped the Black Saturday fires once they started. But a bit of wisdom might have stopped them from starting, or at least reduced the loss of life. But we weren’t wise.
Two acknowledged experts in bushfire behaviour submitted reports to Nillumbik Council prior to Black Saturday. Both reports warned about the dangerous levels of fuel in the Shire. Both reports were ignored. 9 years on, the lessons still have not been learned: when it comes to bushfires, fuel load is the only thing we can actually control.
The Black Saturday Royal Commission recommended mandatory prescribed burns of 5% to public lands each year. They haven’t happened, and part of the reason they haven’t happened is because of the bureaucratic red-tape that’s required before a burn can take place. Sadly, the weather rarely keeps these kinds of ‘appointments’ so either burns are cancelled because the conditions are all wrong – rain or high winds – or they go ahead in less than optimal conditions. And sometimes they get out of control. So even less incentive to do burns.
I’m no expert on bushfire management, but I can’t help wondering why we can’t let the CFA do mini burns every single day that the weather conditions are suitable? Why do burns have to be these big, dangerous things?
When I burn off, I do lots of smaller piles rather than one huge one. It makes sense to me. Mini burns, often. It would work, why can’t we at least try it?
The PALs submission to Nillumbik Shire Council may not solve all our bush fire woes but it would be a huge step in the right direction. Fingers and toes crossed that commonsense finally prevails in the Shire of Nillumbik.

Here in BC we’ve had a few rainy days in a row so most of the southern wildfires are in the ‘being held’ category and will probably, hopefully, die a natural death, but it’s taken its toll.
Hope the PAL’s manage to make a difference before it’s too late.

British Columbia (Canada) has just come through its worst fire season on record. Last summer was pretty bad too. The reasons are very similar to what you noted — too much fuel and the wrong sort of management. Here’s hoping your upcoming fire season won’t be too bad.

That is quite an education on bushfires. I always wonder why, with all the effort in the world, my little pile of sticks smokes but won’t catch in the fireplace. 😉 As for the ground being so dry, it’s exactly like that here after a long, hot and dry summer. Our region is not normally prone to fires but I can imagine it would go up like a tinderbox if it were. Very positive that you are getting some traction at the council level. Fingers crossed!

I lived in Victoria (near Panton Hill) when the Ash Wednesday fires went through. No one should forget that event, either, because they were all warned. Why do they need to be warned, over and over, when the history is all-too-recent? Lives are at stake, and I often wonder how many of the Councillors who make these financial decisions ever volunteered in this critical duty?
I did, and I still have the nightmares to prove it.

Hah! Small world. I did some volunteer teaching out at the Panton Hill community centre a few years back. Must admit I’d tense up every time I drove out there during summer. I know I’m safe in my house. Up there I felt really vulnerable.
I do remember Ash Wednesday, but I was living safe in inner suburbia back then. I’m ashamed to say It felt ‘out there’, way back when. 😦
As for why people forget…they keep thinking it’s a 1:100 year event. Won’t happen again. Just like lightning not striking the same person twice.
You went up there? -shiver- I’m such a coward I still haven’t gathered the courage to drive up to Kinglake.
