AI and fire fighting. What’s going on?

Whether it is in a national park or other public land, a paddock or a house fire, one of the most important aspects of stopping fires is to get on to them quickly. The sooner that firefighters arrive, the smaller the fire will be and the easier it is to contain. In Victoria, one of the ways we try to keep fires small during high fire danger days is by launching aircraft as soon as a fire is detected. Often aircraft can then get on scene and start to contain the fire before local brigades arrive. This system (called pre-determined dispatch or PDD) was developed as part of the  response to the Victorian Bushfire Royal Commission (VBRC), and was based on a model used in a number of other states. Under PDD, fire fighting aircraft are mobilised as soon as a call out occurs for local fire brigades with a trigger needed to authorise the launch of aircraft.

Other ways we get onto fires quickly includes things like deploying remote area firefighters onto new start fires, inserting rappel crews from helicopters, and sending multiple vehicles at the same time to ensure there are enough resources to tackle the fire. We use real time analysis of satellite images and on some days put aircraft up for surveillance (rather than firefighting) purposes. There is lots of chatter about using drones that could carry water or fire retardant that could be sent to put out small new start fires. And of course, we have traditionally relied on staffed fire lookout towers to spot fires while they are small.

In recent years Artificial Intelligence (AI) has been billed as being a new option for spotting new start fires quickly.

Fire: how do we control things when we can’t control things?

The Tasmanian National Parks Association (TNPA) recently dedicated an issue of their newsletter to the question of how to manage wild fire in Western Tasmania. As has been widely noted, including here at Mountain Journal, fires having been getting more intense in western lutruwita/ Tasmania since a ‘tipping point’ sometime around the year 2000. Since then, there has been an increase in the number of lightning-caused fires and an increase in the average size of the fires, “resulting in a marked increase in the area burnt”.

As TNPA notes in the introduction:

The direct impacts of climate change for Tasmania are changes to weather patterns with corresponding changes to levels of temperature, rainfall and evaporation – most likely a warmer, drier climate overall.

The outcomes of some of these changes are beyond our ability to influence. For example, there are no options for protecting an entire landscape from drought, although it may be possible to save examples of individual species.

As discussed in the following essays, the increased frequency and intensity of wildfires is already resulting in demonstrable impacts on some of Tasmania’s most highly valued species and ecosystems (paleoendemics and alpine ecosystems) and options do exist for how it is managed.

Skiing in the Pyrocene

Back in 2022, I helped host an event at Mt Hotham called Climate change, fire and the Alps. I remember being struck by something that was said by one of the speakers. Craig Hore, who at that point was a Ranger in Charge of Fire and Emergency Operations North East District, at Parks Victoria, reflected on his long connection to the mountains. Fire regimes in the high country have changed in the last quarter century, with more frequent and intense fires.

Craig reflected on the fact that since the fires of 2002/3, the mountains have been transformed. With ever more frequent fire and drier conditions, he doesn’t think that we can go back to what the Alps used to be like. In his early days as a Ranger he could drive through older forests for hours. But now so much of the park has been badly impacted by fires. “I doubt we will ever see those old forests again.”

Oregon ash. Whitebark Pine. Ponderosa pine. The Cider Gum. All heading in the same direction.

One of the regular themes here at Mountain Journal is the threats posed to mountain environments by climate change (also called global heating). Climate change is already impacting all ecosystems in the mountains, and we have been seeing declining snow pack since at least 1957. Longer droughts, more intense fires, warmer temperatures, species moving to higher elevations. The impacts are quantifiable and incredibly depressing.

While this information is readily available, there is a strange denial that exists in large parts of the outdoors and mountain communities and certainly in the snow industry. And many others, who are willing to acknowledge what is happening, seem unwilling to commit either time or money to reduce the impacts of climate change. When we have a normal(ish) sort of winter as we experienced in 2025, the snow and mainstream media herald it as a ‘bumper’ winter.

Good news – protection for snow gums gets closer

As you will know, winning a significant campaign can take years of work. I am really pleased to be able to tell you about some great developments on snow gums that we have recently helped achieve.

You may recall that Friends of the Earth (FoE) started working in the Victorian high country in 2021 because there was very limited forest campaign work going on in the north east at the time, and many dire threats of logging in special forests. We released the Icon at Risk report, which made it clear snow gum forests are facing an existential threat from climate change driven fire and expanded impact of dieback. We campaigned for an end to logging in the high country, and developed a rescue plan for snow gum forests.

During the campaign, we have had to deal with three different environment ministers on these issues. Each time we needed to get the new minister and their staff up to speed on the issue, then encourage them to act.

In February this year we hosted the first ever snow gum summit, which allowed us to build the profile of the campaign and give the government more detail about how they need to respond to protect snow gum forests.

And now, after four years of consistent work, we have some great news.

Winter 2025: was it good, average, or an exception?

We’re getting close to October and there is still excellent snow cover across the higher elevations of the Australian high country. After several ‘ordinary’ winters, we really needed this one. Businesses were struggling, workers were facing short seasons and snow lovers were generally depressed. So, 2025 has been the boost we all needed.

I have raved a lot on the website about what a great winter it has been and the snow media has wheeled out the superlatives to describe good snow falls and solid snow pack. Its been truly fantastic.

However, we do also need to remember an important fact. 2025 was not spectacular. It was an average version of what winter should be in the Australian mountains. And sadly, it was an increasingly rare winter – one that started early and maintained good snow pack across higher elevation through to the ‘formal’ end of the season – but which is rapidly becoming unusual, rather than regular.

National Climate Risk Assessment – what it means for mountain environments

The National Climate Risk Assessment (the National Assessment) was released this week. Prepared by the Australian Climate Service, it aims to provide an assessment of risk across 8 key systems and 11 regions on the continent, prioritising key risks both within each system and across systems.

This approach aims to provide an understanding of who or what might be at risk from a changing climate, across different areas of the country and paints a national picture for decision makers, to help them prioritise adaptation actions.

A key finding is that Australia’s climate is already changing and will continue to change into the future. The country is likely to experience more intense and extreme climate hazards, and in some cases in areas where people and places haven’t experienced these hazards before.

It is a complex document and while it doesn’t specifically focus on mountain areas, many references are relevant to the mountainous region of the south east and lutruwita/ Tasmania. Risks from climate change include increased stress from higher temperatures, increased fire risk and continued decline in snow pack.

People and Parks: bearing the brunt of climate inaction

Mountain Journal has run hundreds of articles on the impacts of climate change on wild places in the mountains of south eastern Australia and lutruwita/ Tasmania. Sadly, these impacts are being felt in parks around the continent.

This piece from Madoc Sheehan (originally published here) looks at the environmental and economic impacts of high intensity rainfall events in Paluma Range national park over January/February 2025 and similar climate impacts in the Blue Mountains and Boodjamulla national parks.

VIC government must increase efforts to sustain Ash forests

Ash forests – forest comprised of Mountain Ash, Alpine Ash, or sometimes both – are some of the most iconic forest types in Victoria, or even the world. Covering around 500,000 ha of Victoria and stretching from the Otways to the north-eastern boundary with NSW, their stronghold is in the Central Highlands to the east of Melbourne and through the higher ranges of Gippsland and the north east of the state.

These forests have a complex relationship with fire: these forests can live with some fire – but not too much. Scientifically known as ‘obligate seeders’, after severe bushfire, ash forests are killed, but prolifically regenerates from canopy stored seed. The important point here is that these slowly regenerating forests cannot produce seed for 20 years after they regenerate from fire. This means they are highly vulnerable to shortened fire intervals – the exact challenge that land managers in Victoria are facing with climate change.

Once a mountain ash or alpine ash forest has burnt numerous times, it may eventually fail to regenerate, which can lead to population collapse and a change of ecosystem type. This sounds simple, but ecologically, this is dramatic. A tall forest – high in carbon stocks and habitat – changes rapidly to a short shrubland or grassland.

This not theory. This situation already exists among alpine ash forests. The massive bushfires in 1998, 2003, 2006, 2009, 2013, 2014 and 2019/20 and meant that over 97% of Alpine Ash distribution burnt. These fires overlapped and some areas burnt two to three times across two decades (Fagg et al. 2013; Bassett et al. 2021), leaving 43,000 ha of Alpine Ash forest at risk of collapse (Fairman, 2023).

Mountain Journal has long reported about threats to Ash forests and the need for greater government intervention (check here for some of the articles).

Now people involved in the recovery of Ash forests have recently spoken out about the threats posed to these forests.

Heading off ecological collapse in the mountains

Snow Gums are the classic alpine tree of the Australian High Country. And they’re now at risk.
Snow gums can survive fire. However, climate change driven fire seasons are leading to more frequent fire, which is causing more death of trees and changes to forest structure. Dieback, which is caused by a native beetle, but becoming more damaging due to the effects of climate change, is devastating large sections of the high country. In many places, localised ecological collapse is now occurring.

Dark Days while we wait for the White

I love my backcountry trips and my traditions of getting into the Big Wild. The annual multi day walk in lutruwita/ Tasmania with some mates, the new years eve wander and camp out on Mt Stirling, the road trip to the Snowy Mountains in May. I notice sometimes that half the enjoyment comes from planning and then reflecting on the trip (especially when the actual trip ends up being Type 2 fun).

But this year has been different. After two grim winters, I’ve been obsessing over the forecasts for this season. And as we know they aren’t great. I know that we will get a break at some point, that we will continue to get good and bad winters. But as we pass through another warm autumn, it really does feel like we have crossed some invisible tipping point. As happened with bushfires in the mountains, which suddenly did a ‘step change’ in intensity in the early 2000s, you have to wonder if we have stepped over into a new world where, in Australia at least, our snow pack resembles the boom and bust cycles that have long dominated mountain snow in Tasmania, and less like the consistent snow pack we have generally relied on here on the mainland.

The snow gums of Baw Baw

From Matt Tomkins.

This photo essay was originally published in the Mountain Journal magazine, 2025 edition, available here.

The last few winters I’ve become a bit obsessed with making trips to see the snow gums in  Baw Baw National Park.

Snow gums are beautiful trees. To see them at their best, you really need to be up there in winter. Streaked with incredibly vibrant reds, bronzes, oranges, and yellows and covered \with ice, their vivid colours and twisted forms stand out like flames against a snowy backdrop. It’s one of the most magical things about winter in the Australian Alps, and it’s a sight that can’t be seen anywhere else in the world.

I feel an increasing sense of urgency about making these trips.
