Pulling the Wood Over Our Eyes

Last week, front page headlines in The Age and Sydney Morning Herald announced “Logging likely had significant effect on summer fires: scientists. The story, also covered by the Guardian Australia and the ABC, reported on a research paper claiming to provide “compelling evidence” that timber production had a “significant effect” on last summer’s Victorian and NSW bushfires. The media coverage, included extensive quoting of the paper’s lead author, ANU Professor David Lindenmayer, and one of the other four co-authors, UQ’s Professor James Watson, effectively urging state government’s to close what is left of Australia’s timber industries to reduce the frequency and severity of future fires.

However, the quoted research paper was a mere two-page ‘comment’ published in the journal, Nature Ecology and Evolution. This ‘comment’ included 2 maps, 4 small photos, cited 21 references and described itself as a “summary of recent scientific evidence of the impacts of forestry on these fires”. It concluded with a 400-word discussion of “strategies to limit future catastrophic conflagrations”(1).

That what is essentially just a very small literature review, with no new analysis, was able to generate a front-page headline in major daily newspapers and a 15-minute ABC radio interview of one of its co-authors (Watson), arguably speaks volumes for university public relations units and the determination of some conservation scientists to drive public opinion and reshape government forest policy.

Mark Poynter: Is Native Forestry an Endangered Species?

This should be of some concern to the broader scientific community given the sensationalising of an inconsequential scientific ‘comment’ into something far more significant than what it actually is. In particular, strategically timing its promotion to coincide with notable events – in this case, the start of state and federal bushfire inquiries and announcements of limited salvage timber harvesting in some burnt forests – may well generate the best media coverage, but can also create the perception of an inappropriate academic agenda that may ultimately damage, rather than enhance, a university’s brand.

More important than this is the potential for unwarranted media hype to pervert public policy based on flimsy grounds that ignore common sense and the far greater knowledge of forest scientists and field forestry practitioners. Collectively the ‘comment’ and associated media promotion by two of its authors provides a mix of questionable assertions, exaggerations, and a falsehood, including:

# That logging has had ‘severe impacts’ on 181 forest-dependent threatened species, and has profound effects on fire severity and frequency;

# That post-fire salvage logging ‘can impair recovery and make regenerating forests more prone to further fires’;

# Parts of the forest industry are ‘now calling for increased logging’ within both burnt and unburnt forests;

# Logging increases subsequent wildfire severity by leaving ‘large amounts of debris (up to 450 tonnes per hectare)’ on the forest floor;

# Logging increases fire risk by opening up the forest to wind and sunlight thereby making it ‘far drier’;

# Prescribed (fuel reduction) burning is ‘only effective when done within kilometres of dwellings and very regularly (repeated), around every three years’;

# That due to past logging, East Gippsland forests are burning more frequently than their natural fire interval, which is implied to be from 50 – 150 years.

The first two points don’t withstand scrutiny when viewed in a landscape context. It is simple common sense that while a very small-scale, scattered, and renewable activity, such as harvesting and regrowing patches of forest, may have some minor localised impacts, it cannot have ‘severe impacts’ on landscape-scale parameters such as biodiversity conservation and fire spread, severity, and frequency (2). Ditto for post-fire salvage harvesting, which typically occurs in substantially less than one per cent of burnt forests (3).

Claiming that elements of the forest industry are calling for an expansion of logging is also highly questionable, given that the cited Australian Forest Products Association document is actually advocating better fire prevention through increased fuel reduction by burning and mechanical means in close proximity to towns and alongside major roads. Mechanical fuel reduction may produce some usable logs, but is a far cry from an expansion of logging, especially given that the timber industry stands to be substantially diminished by the loss of designated harvestable forests in the summer’s bushfires.

Claiming that logging increases subsequent wildfire severity by leaving up to 450 tonnes of debris on the forest floor is just totally disingenuous, especially given the background of three of the ‘comment’s’ authors (4). Notwithstanding that the average amount of logging debris is hundreds of tonnes per hectare less than this, these three authors would be well aware that this debris is typically removed by post-harvest burning in the process of site regeneration. Indeed, during Victoria’s 2009 ‘Black Saturday’ bushfires, regenerating logging coupes of up to seven years old were mostly left unscathed due to a lack of ground fuels (5).

The notion that logging makes Australian forests ‘far drier’ by opening them up to sunlight and wind was first articulated in 2009 by ANU conservation scientists on the basis of a small literature review  largely focussed on overseas rainforests with closed crown canopies (6). While suddenly opening a closed canopy can have dramatic drying effects, Australia’s eucalypt forests have open canopies and the effects of logging are therefore far less pronounced.   

Asserting that fuel-reduction burning is virtually ineffective in most circumstances simply exemplifies a lack of practical experience of either the burning itself, or of fighting wildfires where the benefits of previous fuel reduction are obvious. Unfortunately, similarly ill-conceived public comments from arms-length conservation scientists dismissing fuel reduction burning have been a regular feature of the aftermath of the recent bushfires and constitute a significant threat to future fire management and, indeed, to the forests themselves.  

The implied assertion that East Gippsland’s forests naturally burn at greater than 50-year intervals was staggering to most forest scientists and practitioners who have spent time working in an area which is part of one of the three most fire-prone regions in the world. While the region includes some high elevation, wet forest types that would have naturally long fire intervals, the majority of the region’s forests are in drier foothill and coastal areas that would naturally have burnt far more frequently, especially given the propensity for dry lightning storms to ignite many fires each summer.

Highly questionable assertions and findings are not uncommon in any body of scientific literature.  In the past, they would have been quietly considered in the background as part of an evolving scientific consensus which, if appropriate, would eventually inform bureaucratic policy and practice. Nowadays, the publication of research papers about trendy causes, such as “saving” forests from logging, is more often a public spectacle, promoted by its authors and eagerly appropriated by lobby groups to push their agendas via a generally uncritical media. If such papers have conceptual flaws and/or factual errors, they are simply overlooked in the rush to publicise and shape their findings into a politically-attractive message. By the time these errors are unearthed, the attitudes of the interested public and politicians have already been influenced.

The nation’s forest industry sector has endured over a decade of ‘hostile science’ publicising its supposed dire impacts on bushfire frequency and severity, climate change and biodiversity conservation; despite the proportionally very small scale of native forest logging making such impacts either implausible or greatly exaggerated. This has grown into a body of scientific literature that typically ignores wider context (such as scale and proportional extent) to enable exaggerated findings, and is founded on often inappropriate assumptions, problematic evidence, and factual errors that are cumulatively compounding in successive papers (7).

These flaws are in-part due to the reluctance or refusal of conservation scientists to engage with forest scientists and forestry practitioners who could better inform their understanding of management concepts and practices. This is suggestive of an intellectual arrogance amongst academic conservation scientists effectively claiming to know more about managing forests than those who actually carry that responsibility on a daily basis, and who, in most cases, are themselves university science graduates who have spent their careers applying their learnings to real-life land management challenges.

We have long since reached the point where those employed within the forestry sector routinely question whether the primary motivation of the conservation scientists producing these papers is to create a platform for media headlines specifically designed to push a politicised conservation agenda. This latest episode certainly feeds that perception.

1.  Recent Australian wildfires made worse by logging and associated forest management, by D. Lindenmayer, M. Kooyman, C. Taylor, M. Ward, and J. Watson, in Nature Ecology and Evolution, 5 May 2020.

  1. Currently in Victoria for example, just 6% of the state’s 7.1 million hectares of public native forest is designated for timber harvesting and regeneration on an approximate 80-year cycle. The annual harvest area of 3,000 ha, comprises just 0.04% of the state’s total forest area.


  1. In Victoria, collectively following the 2003, 06, and 09 fires, just 0.3% of the burnt forest was salvaged; and the planned salvage harvest (of 3,500 hectares) after the 2019-20 bushfires will affect just 0.25% of the 1.4 million hectares that was burnt.


  1. The lead author of the published ‘comment’, Professor David Lindenmayer, frequently points to his expertise gained after 35-years of research in Victorian forests, and in The Age (30/4/20) referred to himself as the ‘world expert’ on salvage logging! Co-author Chris Taylor is a regular research associate of Lindenmayer in relation to logging in Victorian forests and his profile on The Conversation website says “He has contributed to several reports for forest certification schemes and environmental organisations”. He has also written research papers and articles about the smoke from post-logging slash burning. Co-author Professor James Watson is a former ‘senior campaigner’ for the Wilderness Society (see his profile on The Conversation website) and in that role would have knowledge of basic forestry practices. It is inconceivable they could be unaware that logging slash is burnt as part of post-harvest site regeneration.

  1. Arguably the first of the ‘hostile science’ papers to blame timber production for bushfires was: Lindenmayer et al, 2009 – Effects of logging on fire regimes in moist forests (Conservation Letters 2: 271-77)– which was only a short literature review mostly about tropical forests with only four of the 50 cited references relating to Australian conditions. Despite this, a media blitz initiated by the ANU enabled the paper to become a platform for publicly leveraging the sensational assertion that “Decades of industrial logging in Australia’s wet forests have made them more fire prone, raising urgent fire management issues …”

    The infestation of activists parading as independent knowledge experts at Universities reached saturation point some time ago ably assisted by activists in the ABC who pretend to be journalists. How to reset? Perhaps a pragmatic eye on how government funds are distributed to universities and the ABC might produce some changes but our pollies appear too frightened by the twits to take them on.

    >”This should be of some concern to the broader scientific community given the sensationalising of an inconsequential scientific ‘comment’ into something far more significant than what it actually is” [from the article on the MSM choosing the headline – and the report it refers to]

    Well, it is a concern, but it is the meeja doing the sensationalising of their choice of report. Intellectual honesty is not a concept the MSM are open to. Rather, the lust for power drives them. Those MSM denizens really are the enemies of the people, as are the academics behind their tertiary education. Not a conspiracy, just hard observation.

    The only people to trust with power are those who don’t want it.

  • ianl says:

    And Spiked is aiming at the MSM too:

    Prediction: the meeja will now just do a 180 and rent the air with screams of outrage that aged-care homes are “death” traps – despite previously aggrandising the notion that C-19 only kills “old” (ie. useless) people, who should be shoved aside into indefinite isolation anyway.

    I’m sorry to essentially ignore the central point in this article – the destruction of forestry industries – as damaging as that is, hysteria has damaged a great deal more.

  • Greg Williams says:

    Given the muted uptake of the CovidSafe App, I get the impression that the cries of catastrophe from all and sundry are beginning to fall on deaf ears. The governments relies on us living in a state of fear so that they are able to spend our money with impunity. It’s been going on for years with the climate crisis, with governments pouring trillions of dollars into useless renewables to save us from self ommolation. But now that the climate change crisis is losing its sheen, the corona crisis was like manna from heaven for governments all over the world, and particularly our “oiling squeaky wheel” governments here in Australia. It’s not the existential threats that are killing us, but rather the cries of existential threats from governments, media and, let’s not forget, experts!

    Elizabeth Beare, Michael’s wife.

    Well, here’s a scientific comment: completely log out some Eucalypt forests and destroy the dominance of Eucalypts in some Australian forested areas and plant something that provides better quality logged wood and burns less in forest fires. We’d have a revitalised forest industry within a generation. Also, return some deliberately ‘green’ overplanted Eucalypt areas back to pasture. Open vistas are a great improvement on being hemmed in by ecologically rapacious petrol trees created by millennia of human burnings.

  • tbeath says:

    Thanks for this excellent review of the latest rubbish-ridden sensationalisation. Sadly, this has gained much community support as those spreading the doubtful claims seem impossible to challenge as the media give the impression of only being interested in a headline, not a correction of facts, or hard, investigative journalism.

  • Lawrie Ayres says:

    I have an acquaintance who has a senior position in the Vocational Training area. He once told me his greatest challenge was ensuring instructors were up to date with current procedures and materials particularly in the building industry. He said it was noticeable that trade apprentices would be learning one thing on the job and be taught something quite different in the classroom. His solution was to send the instructors back on the tools to bring themselves up to date. Maybe the same should apply to university academics. If academics had to renew their tenure every few years and re-qualify as it were in their area of expertise it would have a positive effect on their thinking. I mean business leaders and professionals working at the coal face are constantly upgrading their skills and adapting to the changing reality so why not academics?

  • Vicky Baker says:

    Lawrie Ayres if only it could be applied to politicians – having accountants, lawyers and career pollies running departments that oversee our Primary Industries and other sectors important to our sustainability and sovereignty as a nation is counter productive.
