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.
Forest fuel, forest resilience and risks of severe bushfire – USDA fact sheets
John O'Donnell. The United States Department of Agriculture (USDA) Forest Service has recently prepared three useful fact sheets in regards to reducing wildfire risks, hazardous fuels and improving forest resilience ... These documents are valuable reading for those involved in land and fire management in Australia.
Future of timber businesses under fire: Davies, Martin
The Opposition has slammed the McGowan Labor Government’s failure to see flow-on effects of banning native forestry on industries which rely on timber to provide goods and services. Opposition Leader Mia Davies said more than a year had passed since the announcement to end the native forestry industry yet many businesses still don’t have clarity on what their futures hold.
Gliders win in Victorian Supreme Court: Environment East Gippsland
In a landmark decision, the Supreme Court of Victoria has found state-owned logger VicForests has logged illegally, and ruled for the first time that VicForests must protect threatened Gliders. Environment East Gippsland and Kinglake Friends of the Forest brought the case in 2021, to protect endangered Gliders in East Gippsland and the Central Highlands ... The groups are calling for the state Labor Government to end logging now, not in 8 years’ time.
Industry confidence ‘undermined’: VFPA
Timber processors at Heyfield and Yarram may lose more wood supply after the state government announced a halving of the native timber supplied by VicForests by 2024 under the Victorian Forestry Plan ... The chief executive of the Victorian Forest Products Association, Deb Kerr, said the government's actions were totally undermining any industry confidence that it would be able to guarantee supply timber until 2030, as promised.
Fauna protection call
A total of 19 species of flora and fauna have been recommended for interim protection relating to forestry operations, according to the Threatened Species and Communities Risk Assessment report. The next step will be to prepare action statements for each species based on the management needed to conserve them all.
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.
Philip Zylstra’s response #3 – self-thinning forest understoreys and wildfire risk debate
The mapped fire histories of the southwestern forests show that bushfires have been most frequent in forests with dense understoreys promoted by previous burns, and far less common in areas that have not been burned for several decades, allowing the understorey to naturally thin. Two new voices have entered the discussion on this here and made numerous claims, but their ill-informed comments have distracted from the point.
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.
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.
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.
Landmark national bushfire framework to save Australian lives, land and property: Forestry Australia
A landmark new body of work has been released to assist governments and private organisations to tackle Australia’s growing bushfire problem and save lives, land and property. Turning the Goals of the National Bushfire Management Policy Statement into Objectives and Key Performance Indicators aims to guide improvements in bushfire management and provide consistent reporting nationally on achievements.
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.
Historic new plan to protect WA’s forests: Whitby, Kelly
Western Australians can now have their say on the draft Forest Management Plan 2024-2033, which delivers on the McGowan Government's historic decision to end native logging in our South-West. The move will preserve at least 400,000 hectares - an area 1,000 times the size of Kings Park - of karri, jarrah, and wandoo forests.
Forest scientists concerned by lack of evidence and dismissal of expert modelling: Forestry Australia
Documents released under a Freedom of Information request have exposed a lack of evidence-based decision making by the Western Australian Government in relation to management of native forests, according to the organisation that represents professional forest scientists and managers. Chair of the WA Branch of Forestry Australia, Brad Barr, said revelations that the decision to end native forest timber harvesting was not backed up by scientific evidence gave reason to question the Government’s motives.
‘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.
New release – The 1982-83 Victorian Bushfire Season, Including Ash Wednesday – 16 February 1983 – A Forester’s Perspective
Forty years ago, south eastern Australia was in the middle of a prolonged drought and facing a perilous bushfire season. A new e-book by retired Victorian forester, Peter McHugh, provides a detailed account of the 1982-83 bushfire season from a new perspective ... It was a long and hectic fire season for the Forests Commission Victoria (FCV) which attended 878 fires on State forests and National Parks totalling 486,030 ha, which was well above the 11-year average of 141,000 ha.
Softwood plantings
Victorian Agriculture Minister Gayle Tierney said the agreement with Hancock Victorian Plantations involved planting an extra 16 million trees to create a new forest estate ... The Nationals Leader, Peter Walsh, slammed the policy as a replay of a $110-million investment, the Gippsland Plantations Investment Program, announced in 2020.
