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.

First summer fire in the VIC mountains

The awful fires of Black Summer linger in our memory. The land slowly recovers. Since then, things have been fairly quiet in recent summers in the mountains of the mainland high country. With the first mountain fire of the season now contained, and vast areas of fire damaged forests in recovery from previous fires, it is essential that with any new start fire the authorities:

  • Get on to new start fires as rapidly as possible
  • Escalate the availability of resources to contain the fire, rather than ‘letting it burn’
  • Ensure that fire management plans highlight the need to exclude fire from fire sensitive or recovering areas and the protection of ecological as well as human assets.

FFMV fleet ‘offline’: what does this mean for the high country?

DEECA and Forest Fire Management Victoria have grounded the entire ultra-light firefighting fleet in Victoria just weeks before fire season commences.

Forest Fire Management Victoria (FFMVic) and the Department of Environment, Energy, and Climate Action (DEECA) have grounded their fleet of 290 Mercedes-Benz G-Wagons and 59 Unimogs. According to reporting from the ABC this was due to safety concerns. There are reports of cracking in the chassis of G-Wagons.

What will this mean for fire fighting in the high country?

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.

Best practise fire fighting

The 2024/ 25 fire season was a long one in south eastern Australia.

While there were large and destructive fires in western Victoria (particularly in the Grampians (Gariwerd) National Park and Little Desert National Park – details here), there were no enormous ones in the mountains. But if you track what happens in the high country, you will recall that we did have a number of significant ones last summer, including the Mt Matlock fire in the Thompson River catchment (which provides drinking water for Melbourne) and the Mt Margaret/ Licola fire, which grew to around 5,600 hectares. There are some resources on these fires available here.

There is a significant story from this latter fire which is worth retelling.

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.

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.

Planned burn in biodiversity hotspot

This summer has seen sustained community campaigns against specific fuel reduction burns, from Flowerdale to Gippsland. Now Friends of Bats and Habitat have raised the alarm about a large burn which is planned for the Mitchell River National Park.

Roaring Mag: There are so many redflags with this remote 1,875 ha Forest Fire Management Victoria (FFMV) burn which is expected to be ignited within ten days in the Mitchell River National Park. A rapid desktop survey brings up a whole of suite of threatened, rare and endemic flora and fauna records within this burn site. Dropping off cliffs are waterfalls, sheltered narrow gullies, large areas of old growth forest, and the most southern occurrence of warm temperate rainforest … If you went looking for a Spot-tailed Quoll, this is where it might be.

Fire near Mt Howitt

Recent dry lightning caused a number of fires across the Victorian high country. Most were quickly contained but one just north of the Howitt Plains is becoming a concern.

This area, of high elevation snow gum woodlands inter-spaced with grass dominated plains, has been burnt several times in recent decades, with many areas now holding thick (and highly flammable) regrowth forests. Fires in these recovering forests can lead to ecological collapse – that is, the loss of snow gum dominated forests, which are replaced by grass and shrubs. It is essential that we exclude fire from these ecosystems as they recover.

A new fire fighting team for Victoria

On Tuesday November 12, lightning started a fire in remote country north of Valencia Creek in the Victorian high country.

On Wednesday November 13, two rappel crews from Forest Fire Management Victoria (FFMV) were airlifted into the Avon Wilderness to fight the fire.

The crews created a mineral earth break around the fire and spent two days extinguishing hotspots before it was announced that the fire had been contained. In total the fire burnt around 1.3 hectares of forest. (Source: FFMV facebook).

This sort of early intervention is what is needed to stop small fires from turning into uncontrollable blazes.

Black Summer biodiversity study suggests rethink of prescribed burns and fire management in Australia

 

This is not ‘new’ news. But it does add to the conversation that is underway about the role of prescribed burning (also called planned burning and fuel reduction burning) in terms of reducing fire risk.  

A new study examining plant and animal species after the Black Summer fire season has found greater biodiversity loss in areas that have been subject to frequent burning. Six ecosystems were considered, including alpine, wetland, rainforests and dry and wet eucalypt forest.

Sites with three or more fires in the 40 years leading up to the 2019–20 Black Summer were far more negatively impacted than previously unburnt areas or sites that had burnt once during that time.
