‘They offer great beauty. They offer shelter. They nurture us.’

Across the Australian high country, the snow gum woodlands are facing an existential threat from dieback and climate change driven fire regimes.

These threats are detailed here, as are some potential solutions.

While the loss of these forests would have major physical and ecological impacts on mountain environments, what would it mean for our personal connection to the high country? For me these trees are an essential part of life in the mountains. When I drive or walk up from the valley and have a wander among old trees, I feel like I have come home. I know these forests have been here for time beyond our imagining:

‘Long-unburnt snow gum forests are now exceedingly rare’.

Across the mountains of south eastern Australia, climate change is already driving profound change. In many places in the high country of NSW and Victoria, snow gum forests are facing a double sided threat: dieback, caused by a native beetle is killing individual trees, and climate change driven fire regimes are devastating vast areas of forest. Climate change, drought, insects and soil microbes are all thought to contribute to dieback. The spread and impacts of the beetle appear to be super charged by climate change (more beetles are surviving because of milder winters and more mortality of water stressed trees in summer).

More frequent and intense wild fire also poses an existential threat to the survival of snow gum woodlands and forests. A new report reveals the scale of the fire impact on these forests in the Victorian high country.

In the paper ‘Long-unburnt stands of snow gum (Eucalyptus pauciflora Sieber ex Spreng) are exceedingly rare in the Victorian Alps: implications for their conservation and management’, John Morgan, Michael Shackleton and Zac Walker from the Research Centre for Applied Alpine Ecology at La Trobe University highlight that ‘Long-unburnt snow gum forests (now) comprise less than 1% of snow gum forests in the Victorian Alps. We identify where long-unburnt snow gum stands persist in the Victorian Alps and outline why management intervention is necessary to protect unburnt refuges and, more broadly, to allow mature/adult stands (such as occur on the Baw Baw Plateau) to develop into future old forests’.

Profile: Hilary McAllister from For Wild Places

Hilary McAllister describes the development and role of the trail running group For Wild Places.

Activism and the outdoors are two pursuits that, in recent years, have evolved into a symbiotic relationship.  As history would have us believe, activism is a pursuit of the immensely passionate. Dedicated souls who shun societal expectations, choosing to reside in remote, sometimes damp, forest camps, utilising our scarcest resource – time – to protect wild places under threat.

Growing up in an average, rural family, this path to activism felt out of reach to me, too extreme for my somewhat beige sensibility. But along with descriptors such as accident-prone, nomad and feminist, activist has made its way onto my bio and into my way of life.

MJ turns 14

JAN 2024

What even happened last year? Another mild summer, no big fires, then truly dazzling amounts of autumn snow, a great start to winter, then, nothing. Rain and warm temps and misery and the snow pack was gone, not to return. Early end to the season in many places, especially the lower resorts. The usual denial and grumpy guys ranting on line if you dared to mention the ‘climate’ word. Muddy spring and now, another mild summer – a bit different to the El Niño scorcher we had been expecting (so far at least).

Yes, this is the new reality. Climate systems turned on their heads. Wild floods up north, while more than 14 million hectares burnt across the Northern Territory alone during our spring. Erratic winters and wild swings of weather. Buckle in, because it’s not going back to ‘normal’ any time soon.

Then there are the wars raging across many parts of the planet.

And yet, the world can still feel right. Those long autumn days with a slow wander across snow plains, the light rich, the air cool, the distant peaks calling. We are blessed to live in a safe corner of the planet with beautiful hills and forests, rivers and high plains. The freedom and safety to explore. Let us be grateful, as we work for a better world for all.

Welcome coverage of threats to snow gums in The Age

You may have seen today’s story by Miki Perkins in The Age here.  It considers the threats posed to snow gum woodlands (and other mountain forests) by more frequent and intense bushfires.

The story says ‘the global climate crisis, driven by humans burning fossil fuels, has brought a new threat to these mountain peaks: more frequent and more intense bushfires.

Because snow gums have not evolved to cope with these conditions, experts say the nature of Australia’s high mountain landscapes are changing, and the ecological collapse of snow gum woodlands – the abrupt decline or change of this ecosystem – is happening before our eyes’.

California acquires 7 large firefighting planes – could Australia use this model?

We know that there is growing pressure to increase our fleet of large firebombers. There are Large Air Tankers (LATs) and ‘Type 1’ helicopters which can carry large loads of water/ retardant and which can have a big impact in terms of slowing fires so ground crews can then fight them.

Australia generally needs 6 or 7 LATs in an average summer, and only two of these are located here year round (and only one is actually owned locally, by the NSW Rural Fire Service). The others are leased in from the northern hemisphere for the fire season. As climate change causes fire seasons to become longer in both hemispheres, relying on leasing them becomes a riskier and more expensive proposition.

That has led to proposals to buy our own national fleet of LATs. This was recommended by the Bushfire Royal Commission into the 2019/20 Black Summer. The Commission recommended ‘The development of a modest Australian-based and registered national fleet of VLAT/LAT [Very large Airtanker/Large Air Tanker] aircraft and Type-1 helicopters, jointly funded by the Australian, state and territory governments, will enhance Australia’s bushfire resilience’.

It has also prompted conversations about whether we can repurpose aircraft that are already owned by the Australian Defence Force that are nearing the end of their military working life which could be re-purposed to become firebombers (there are some notes here about converting Lockheed Orion planes from the RAAF into firefighting aircraft, with a variety of views about the viability of this proposal).

Even in North America (where we lease our LATs from) there is increasing competition between agencies and states to access large firefighting aircraft. In an announcement (published by Hotshot Wake Up, a podcast that covers all things fire based in the USA) it has been noted that California has acquired 7 publicly owned C-130 planes, which are being transferred from the Coast Guard and which will be retrofitted to be able to be used to fight fires. The announcement states that they will also be used for ‘search and rescue, and emergency operations related to wildfires’.

Surely this is an indicator of options the Australian government could be pursuing here to build the number of publicly owned large air tankers.

Save our snow climate data – we won!

The following information come from Protect Our Winters (POW) Australia.

After POW alerted the winter snowsports community to the fact that that the frequency of snow data collection at Spencers Creek in the Snowy Mountains has decreased in recent years, Jeremy Kinley, Acting Manager of water for Snowy Hydro, has confirmed that “we have agreed that we will commit to more regular measurements at Spencers Creek from next year onward.”

The data on snowpack collected by Snowy Hydro provides our best snapshot of snow pack over time. Earlier in the year, POW reported that:

‘Data collected in 2022 was sparse in comparison to previous years, with only four records collected from 1st of May to 31st of July. This is a reduction of over 60% compared to the average of the previous decade (2012-2021). 

‘Snowy Hydro explained their reduction in data collection in 2021 as a means to avoid sending staff to remote locations in poor weather conditions.

POW launched a campaign to get Snowy Hydro to continue recording their valuable data on a weekly basis from the first snowfall throughout the season. This campaign has been a success. Congratulations to everyone involved.

FORUM: The Future of Firefighting in Victoria

It is quite a few years ago now that I stood on the high point of Mt Blowhard, near Hotham, and watched the Dargo High Plains burning (yet again). That led me on my ‘firefighting journey’ – I went back home and joined the CFA. In the years since then I have seen the reality of more frequent fires in the mountains and the fact that sometimes we don’t have enough firefighters to stop small lightning strike fires from turning into mega blazes.

One example – a couple of lightning strikes near Mt Tabletop on December 31, 2019 (during the Black Summer) were not able to be stopped. They grew into a fire of more than 40,000 ha that threatened the township of Dinner Plain twice and homes in the Cobungra valley.

That’s where this idea came from – an additional force of remote area firefighters who can be tasked with assisting the wonderful state government firefighters employed by FFMV.

The proposal will be discussed during a free online forum being hosted on Thursday December 14 at 7pm.

Victorian State of the Environment 2023 Report released

The Victorian State of the Environment (SoE) 2023 Report has been released. These are five-yearly report cards produced by the state government which measure the health of our natural environment – our land, water, air and ecosystems. The report covers three key areas:

  • the health of Victoria’s natural environment
  • the adequacy of our science
  • areas for future focus.

The Greens labelled it ‘a damning new report (which) has found Victoria’s ecosystems and threatened species are in a far more dire situation now than they were five years ago’.

They say ‘It found that biodiversity and climate change indicators were particularly bad, with more than 75% of biodiversity indicators (32 of the 42) deteriorating or unclear, and 73% of climate change health measures (11 out of 15) also deteriorating or unclear. Only 1 out of 57 were classed as good (which related to the number of Victorians taking action to protect nature)’.

While I don’t have time to do a deep analysis of the report (which is available here), a quick look at the categories related to mountain areas are all fairly depressing. In short, there are no positive trends that are obvious.

Are we ready for the next Black Summer?

Firefighters say dry lightning has caused more than a dozen fires across Queensland this week, sparking concerns for authorities battling El Niño conditions.

As reported by the ABC, senior meteorologist Steve Hadley from the Bureau of Meteorology said dry lightning occurred when there was no significant rainfall, particularly during “overarching dry conditions”.

“Sometimes with not enough significant rainfall, of a few millimetres or more, that can mean lightning is essentially happening over drier areas and drier terrain with no rain to follow it up,” he said.

“Then you can get some fires starting from that depending on how the landscape is at that time.”

The threat from dry lightning caused fires continues to increase in mountain environments. To take one example, multiple lightning strikes across the Victorian high country on December 31, 2019 resulted in fires developing, including the 44,000 ha Cobungra fire which threatened Omeo, Anglers Rest, and Cobungra.

Are you suffering from Shifting Baseline Syndrome?

How often do you see an image or vista like this when you’re in the mountains? Whether you drive up from the valley towns through mile after mile of grey alpine ash trunks, or wander, ski or ride through the snow gum ghost forests of the high plains, you are witnessing a world that didn’t exist a generation ago.

Whereas we would have infrequent hot fire in the high country in the past, now we have fire on endless repeat. The forests get younger as we get older, yet this new reality of dead trees and thick regrowth becomes understood as being ‘normal’. Many people don’t recognise that what they see as they look out from a ski resort over burnt out hills is actually ecological collapse in real time.

Are we all just witnessing a deteriorating landscape and thinking it is ‘normal’ because we don’t have a memory of what was here before?
