Caring for national parks – a conservationist’s perspective evolves: Cam Walker, Friends of the Earth
Cam Walker. After World War Two, a growing appreciation of the Australian landscape and an emerging conservation movement led millions of people to become involved in campaigns to protect our wild and special places ... Once a campaign was won, we often thought that the battle was over ... Several decades ago I was a volunteer with an environment group that campaigned to gain protection of wild ecosystems. In those days I supported a ‘let burn’ policy when it comes to managing fire in wild landscapes.
North Queensland flood warning infrastructure project complete: Miles
An $8 million project to upgrade North Queensland’s flood warning network is now complete with 180 new flood warning assets installed across 28 council areas in the Far North, North and North West of the state.
Undera update – the water recedes, the community hopes to future proof
Daryl Wiltshire from Undera reports that while the floodwaters are receding, the community is waiting and hoping that the rain that is forecast will not affect the region too much. Undera people are "hoping for a show of resolve from the authorities who control levees to future flood proof the farming area."
Peter Rutherford to Philip Zylstra #2 – self-thinning forest understoreys and wildfire debate
Both researchers I referenced show regular low intensity burning, as practised by Aboriginal people across the landscape, has been lost and Dr Fletcher believes the loss of cool, mosaic burning since European settlement has left us, as a nation, dangerously fire prone. Philip Zylstra seems to have missed this critical point.
Jack Bradshaw to Philip Zylstra #2 – self-thinning forest understoreys and wildfire debate
In his 24 October response on this issue, Zylstra states that in their study seven times more area of recently burnt forest was burnt than long unburnt forest. That is not in dispute. But was this because there were seven times the number of ignitions in these areas to start with because of chance or differences in area or because of some flammability factor? We simply do not know because this basic statistical requirement was not considered in the study. Is the conclusion biased, by how much, and in what direction? Who knows?
Think fire, know fire: Roger Underwood
I have recently re-read Think Trees, Grow Trees, a 1985 publication from the Institute of Foresters of Australia. This excellent little book was the brainchild of, and was edited by Dr Wilf Crane, one of my contemporaries at the Australian Forestry School, a notable forest scientist and famous and eccentric character ... To me, the most important part of the book (in terms of contemporary relevance) is the chapter called Living with Fire. It is written by Phil Cheney.
Dialogue to help Gippsland’s forests
Scott McArdle is blunt. “Gippsland’s forests need our help. Fire, floods, storms, drought, pests, weeds, neglect, exploitation and the changing climate are all taking a huge toll – but if we all work together, the future can be different.” Mr McArdle is the executive officer of a new group, the Gippsland Forest Dialogue (GFD), that aims to do just that – meet the challenges facing the region’s forests and find ways to move forward.
Residents relieved as Marton Swing Bridge re-opens ahead of schedule
Cook Shire Council is pleased to announce that with repairs to the approach ramps of the Marton Swing Bridge coming to completion, the bridge is scheduled to reopen in coming days – ahead of the approaching wet season.
Philip Zylstra’s fire research: Adding value or creating risk? : Peter Rutherford
Following the critique of a research paper by Zylstra, Bradshaw and Lindenmayer “Self-thinning forest understoreys reduce wildfire risk, even in a warming climate,” by Jack Bradshaw, readers might be interested in some broader analysis of Mr Zylstra’s fire research work ... His research appears to be the base to advocate for what might be described as a wilderness approach to fire management across the broad Australian landscape.
Politically correct fire management
Elders of Australian forestry temporarily reinstated sustainable fire management more than half a century ago, before a new generation of ecologists dismantled it. These new experts employ the Climate Cop-Out to explain the inevitable resurgence of pestilence and megafires. Now Forestry Australia is collaborating with them to ‘reimagine’ our future. To achieve this, they have to reinvent our past.
Albanese and King – throwing rural communities down the drain – literally
For rural and regional communities, especially those crying out for dams for flood and drought mitigation for decades, Budget Paper Number 2 from the Commonwealth 2022-2023 Budget makes depressing reading.
Undera – the community left to take responsibility
As at 26 October, the flooding continues at Undera and, with no authority prepared to take responsibility for the levees, it's left to the community - somehow, sometime - to repair the multiple levee breaks.
Philip Zylstra continues the debate – self-thinning forest understoreys and wildfire risk
Our paper published in 2022 shows that, according to DBCA records, bushfires have been seven times more likely on land previously burned by them than on land that they have not burned. Mr Jack Bradshaw’s educated guesses about the causes of karri regeneration prior to 1850 do not change this, they use speculation to distract from the hard evidence we are discussing.
Statement on Australia signing the Methane Pledge: NFF
Farmers have been given assurances there will be no new taxes or regulation on livestock methane, and no reduction to agricultural production nor livestock numbers. This commitment recognises agriculture’s existing achievement, future plans and dedication to ongoing partnership with government to develop technology-led solutions and associated innovation. We are confident Australian agriculture and farmers will retain a seat at the table as the conversation continues and this dialog with government is open and dynamic.
Self-thinning forest understoreys and wildfire risk debate – Jack Bradshaw responds to Philip Zylstra
In his response to my critique of his paper, Zylstra agrees that the proportion of an area burnt is influenced by the likelihood of a fire starting and the effect of the fire suppression effort. He also agrees that these factors were not taken into account. The degree and direction of bias in their results in therefore unknown, invalidating the results. This is exacerbated by the fact that they have treated the dry north-eastern jarrah forest and the wet karri and tingle forests, with their very different fire behaviour, as one type.
MINCo continues plan traditions
Last week, the Murray-Darling Basin Authority sang the praises of the Murray-Darling Basin Ministerial Council (MINCo) meeting outcomes. Hot topics were climate change, delivering the Murray-Darling Basin Plan in full, water buybacks and First Nations water. When it came to the almost $2 billion unregulated water trading industry that impacts communities, rural economies and the environment, it seems implementing legislation already in place was not on the radar.
Undera – left to its own devices during the flood
The small community of Undera in northern Victoria is pulling together during the floods. It has been reported to Australian Rural & Regional News that, as at 18 October 2022, it had had no assistance from council, the ADF or any authorities with sandbags, levees or with fighting the flood ... It is concerning that this dire situation may be being repeated across a wide area of rural and regional Victoria.
Echuca prepares – and waits
Updated flood news from Echuca. As at 25 October 2022, the Murray River at Echuca is up slightly. Those that can enjoyed some sun at the coffee shops and restaurants that are opening in the town.
Review – Farm – the making of a climate activist
A good place to start reading Farm is at the back. That may sound counterintuitive but by taking a look at the extensive bibliography you’ll quickly see how intensely researched the book is which adds weight to the arguments and questions it presents. While Farm is a memoir that chronicles the journey of Nicola Harvey and her husband after they leave their city lives to farm cattle in rural New Zealand, it is far more than that.
NSW Farmers says ‘no’ to Methane Pledge: NSW Farmers
The state’s peak agricultural advocacy body says it is opposed to Australia signing up to a global ‘methane pledge’ that is killing small towns across the ditch ... NSW Farmers CEO Pete Arkle said while the federal government had been quick to promise no tax on farmers if it signed up to the Methane Pledge, the experience of New Zealand’s farmers proved talk was cheap.
‘Self thinning forest understoreys reduce wildfire risk, even in a warming climate’: Philip Zylstra responds to Jack Bradshaw
Mr Bradshaw has expressed concerns about the methodology in our paper, but unfortunately, he seems to have fundamentally misunderstood what we did. Without going into that complexity, we will address his core argument here: that the proportion of an area burnt each year is dependent upon the likelihood that a fire will start there, and the amount and effect of fire suppression that occurs there. We thoroughly agree, but the question is whether this reality biases the trends in a way that will cause our results, as he has suggested.
Comment on ‘Self-thinning forest understoreys reduce wildfire risk, even in a warming climate’: Jack Bradshaw
Earlier this year a paper was published in an international journal that argued that if left long enough the southern forest of Western Australia was ‘unlikely to burn’. Furthermore that ‘the predicted likelihood of fire in undisturbed forest was 1 in 208 to 1 in 1149 years.’ In my opinion, the methodology used to obtain the results was so badly flawed as to make the conclusions meaningless.
