Self-thinning forest understoreys and wildfire risk debate – Roger Underwood responds
Dear Editor, I am compelled to respond to the naïve and dangerous comments by Professor Phillip Zylstra on forest bushfire management in Western Australia, in your most recent edition. I agree with the Bradshaw critique of Zylstra et al’s paper and I found Professor Zylstra’s defence to be unconvincing.
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.
‘Precious, unlogged, unburnt’
Murdoch University sustainability lecturer Nicole Hodgson describes the central core of Mt Hallowell reserve as precious unlogged, long unburnt forest. This was mostly karri, jarrah, marri, sheoak, and more than 100 other plant species. Home to many animals and more than 70 bird species, some in the reserve were critically endangered like the Carnaby’s and Baudain’s cockatoos.
Premature peak?
Somebody better tell mother nature to get with the program as Koondrook-Barham’s peak was exceeded seven days early. The expected peak for Koondrook-Barham remains unchanged on official channels at an expected 6.2m. Mother nature had other ideas with a rainfall event on Monday, October 24 pushing the river to an eye watering 6.210m just one centimetre short of the highest recorded on NSW Water, the 1917 flood reaching 6.223m.
Rural Aid assisting farmers reeling from floods
Farmers in the Darling Downs have had to contend with four floods in six months from November 2021 to May 2022 while elsewhere in Queensland and northern New South Wales the damage has been widespread and devastating. Following flooding down south in recent weeks, Rural Aid’s team of counsellors are conducting welfare checks on Rural Aid’s registered farmers.
Gondwana Link sends letter of warning
A Letter from Gondwana Link to Premier Mark McGowan warns of the impact of mountain bike trails on the connectivity and integrity of the bush. It also warns of the increasing fragmentation of ecologically valuable habitat. Mountain bike trails (and other high intensity trail networks) are described as fundamentally incompatible with the aims and goals of conservation.
Big wet causes chaos
More than three times the average October rainfall has already fallen in Narrandera this month with more than 100mm drenching Narrandera in the first three weeks of October. The deluge has caused chaos with many roads being closed.
Calls to raise dams walls
Recent rainfall and flooding has resulted in further calls to raise the Wyangala and Burrinjuck Dams walls. Federal Member for Riverina Michael McCormack has reaffirmed his support for raising the Wyangala Dam wall after the Prime Minister and NSW Premier visited Forbes last week.
“We won’t go”
Kirstin Nicholson. Pat and Michelle Quinn’s dairy farm at Mincha West is under real threat of flooding. The 700 head dairy property sits about 3km from Flannery’s flume, and the water coming out of Kow Swamp backs up and flows over the top of the property ... In 2011, the farm was completely inundated – and Pat is predicting this flood will be the same.
Kerang isolated again
Kendall Jennings. Amidst the sound of helicopters, drones and light aircraft, the community of Kerang gathered to do whatever was needed to protect vital infrastructure as the Loddon River, Nine Mile Creek and Pyramid Creek water levels rose. Earthmoving machinery was used, along with sandbags to contain floodwater away from major roads, however, some efforts did not survive the floodwater onslaught.
Murray-Darling Basin Authority communique, 24 October 2022
When viewed together the 30 major dams across the Murray-Darling Basin are currently at 101% capacity and hold an unprecedented volume of water in storage ... At the Authority’s invitation, the South Australian River Murray Commissioner, Mr Richard Beasley SC, attended the meeting. He provided an update on his appointment to advocate for the health of the River Murray, Lower Lakes and Coorong.
Widespread flooding raises risk of water quality issues in the Murray–Darling Basin: MDBA
The Murray–Darling Basin continues to experience widespread flooding in some areas, prompting an increased risk of water quality issues like low-oxygen blackwater as temperatures increase. Governments and water authorities are working together to monitor the unfolding conditions which may see low-oxygen blackwater and blue-green algae emerge that can lead to fish deaths and increased water treatment.
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.
Regional Budget Statement: King
I am very pleased to the deliver the Regional Budget Statement on behalf of the Government ... This Budget delivers on our election commitments and provides funds for the Government’s purposeful and targeted approach to investing in regional Australia. It contains more than 760 initiatives which the Government is delivering to boost regional communities and industries.
Not just a wildflower walk
These amazing images were taken by Allora’s Photography Group when visiting Girraween National Park. Members of the Group joined other Wildflower Walkers and were led by knowledgeable guides from the Stanthorpe Rare Wildflower Consortium.
Another tourist attraction for Allora
A local lizard lover has been keeping a watchful eye on a lounge of Cunningham Skinks in Muir Street at Allora. These lizards will remain safe from any harm as they disappear in a flash if danger comes close. So look but don’t try to touch!
Highway upgrades achieving flood immunity objectives
Rodney Stevens. A hydrological mitigation report on the Glenugie to Devlis Pulpit section of the Pacific Highway published by Transport for NSW shows the upgraded road is achieving its objectives of improving flood immunity. The report describes flood behaviour in the region, Transport for NSW’s flood management objectives, flood model outcomes, design and mitigation, and future planning.
Citizen scientists find 60 endangered gliders in forest slated for logging: Kinglake Friends of the Forest
On the night of October 2nd, 66 citizen scientists surveyed for endangered Greater Gliders in native forest across Victoria. The state government has either released these areas of forest for logging in the current Timber Release Plan or plans to release them under the proposed Timber Release Plan (TRP). Surveys were carried out in six locations across the state: Toolangi, Black Range (near Taggerty), Warburton, Wombat, Alberton West, and Colquhuon forest, East Gippsland ... ARR.News ask KFF a few questions.
‘I’m back home’: Flood displaced people move into pods at Coraki
The first 40 flood displaced residents to move into temporary housing at the Coraki pod village were officially handed the keys by the Minister for Flood Recovery Steph Cooke on Friday, October 21. There are 56 units at the Spring St site with the capacity to house up to 240 people.
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.
When Green idealism fails to yield
In 1971 the United States Secretary of Agriculture, Earl Butz spoke wisely and bluntly about the perils of organic farming. “Before we go back to organic agriculture in this country, somebody must decide which 50 million Americans we are going to let starve or go hungry.”
