Alpine and Mountain Ash face potential declines in a warmer and drier future.

We know that the Alpine Ash forests are struggling to survive in the face of climate change driven fire regimes that are bringing fire into these forests more frequently.

The scale of this threat is so extreme that the Victorian government has a program specifically responsible for reseeding forests that are on the verge of ecosystem collapse.

New research underscores, yet again, that the mountain forests face grave threats from climate change and that this could lead to the transformation of these forests.

Fires in Tasmanian World Heritage Areas

Back in 2019, Tasmania/ lutruwita was badly impacted by wildfires (check here for a diary of those fires). With much of south eastern Australia experiencing a La Nina mild summer, the forecast is for a ‘mild’ season across most of the south east.

But following lightning storms over the weekend of December 18 and 19, 2021, a number of fires have started in remote World Heritage Areas in Tasmania/ lutruwita. It has been noted that since the year 2000, there has been an increase in the number of lightning-caused fires and an increase in the average size of the fires in Tasmania, “resulting in a marked increase in the area burnt”.

This page will track significant fires on public lands in Tasmania during the summer of 2021/22.

Snow Gum citizen science field trip – January 2022

Snow Gums face a massive threat from the spread of dieback which is caused by a native beetle – and also super charged by climate change, and localised collapse of snow gum woodlands due to more frequent fires.

Last winter Friends of the Earth (FoE) published An Icon at Risk, which considers the many threats to the mountains of north east Victoria (the report is available here).

FoE will be hosting a field trip to map impacts of fire over four days in January 2022 in the Mt Hotham region.

International Mountain Day 2021

December 11 is International Mountain Day.

Around the world, mountain environments are threatened by climate change and destruction of natural environments. It is the same here in Australia, where we are starting to see the local collapse of mountain forests – both Alpine Ash and Snow Gum – due to climate driven fire regimes (and, in the case of Snow Gum, dieback caused by a native beetle).

There is much we must do to protect these wonderful environments, including building our capacity to fight fires effectively in mountain areas.

Here are some ideas.

And please join the citizen science project if you’re planning on visiting the VIC/ACT/ NSW mountains this summer.

Help identify and report Snow Gum dieback

Snow gums are experiencing dieback in Kosciuszko National Park, largely because of the impacts of the native longicorn (or ‘longhorn’) beetle. These beetles prefer to lay their eggs on moisture-stressed trees and, in warmer weather, the longicorn beetle can hatch and grow up to 75% faster. It is understood that climate change is helping the spread of dieback because of background warming.

Now dieback is being seen more frequently in the mountain forests of Victoria.

Jessica Ward-Jones, a PhD student at the Fenner school, is part of a group researching snow-gum dieback, and is asking for people visiting the mountains to send in details of sightings of dieback affected trees.

‘The places humanity must not destroy to avoid climate chaos’

Detailed new mapping has pinpointed the carbon-rich forests and peatlands that humanity cannot afford to destroy if climate catastrophe is to be avoided.

The vast forests and peatlands of Russia, Canada and the US are vital, researchers found, as are tropical forests in the Amazon, the Congo and south-east Asia. Peat bogs in the UK and mangrove swamps and eucalyptus forests in Australia are also on the list.

This highlights the need to protect the carbon dense forests of south eastern Australia which are still being subjected to clearfell logging.

Climate change and rise of the ‘mega fire’

Recent research by CSIRO, Australia’s national science agency, shows that climate change has driven a ‘significant increase’ in Australia’s forest fire activity over the last three decades.

A lengthening of the fire season towards Autumn and Winter were also identified, along with an increase in fire activity in cooler and warmer regions including alpine forests in Tasmania and tropical rainforests in Queensland.

This is not really ‘new’ news. The impacts of climate change in terms of length of fire season and intensity of fire is well documented (for instance, the head of the firefighting agency for Victoria’s public lands, Chris Hardman, notes that there has been a 170% increase in bushfire ignitions over the last 50 years, a 20% reduction in spring rainfall, and a 40% increase in very high and severe fire risk days.

What is especially interesting is that this research, which was published in Nature Communications is the first of its kind in that it combines analysis of previous forest fire sites with eight ‘drivers’ of fire activity including climate, fuel accumulation, ignition and management (prescribed burning).

Parks Victoria Hawkweed program – summer 2021/22

This summer, Parks Victoria (PV) will continue its volunteer program which is working on eradicating the invasive Hawkweed from the Bogong High Plains.

Hawkweeds are a highly invasive pest plant species which could cause major environmental damage in alpine and sub-alpine areas of Australia if not eradicated early.

PV have now added some volunteering dates for this summer. There will be four one day sessions available on the following dates;

Friday 7th January, 2022

Friday 14th January, 2022

Friday 21st January, 2022

Friday 28th January, 2022

Three ways to watch the Backcountry Film Festival

Presented by Winter Wildlands Alliance each year, the Backcountry Film Festival screens stories of outdoor stewardship, grassroots policy and advocacy work, backcountry adventure, and snow cinema by human-powered advocates, athletes, activists, and outdoor enthusiasts.

The 2021 festival will run from DEC 3 – 13 and features 14 films over two hours.

The festival is shown around the world. In Victoria, Friends of the Earth is the local host.

There are three options to watch it this year.

Calling mountain firefighters

You may have seen that we are now producing occasional print runs of a Mountain Journal magazine. The first one came out in August this year, is slowly being distributed, and available as a PDF here.

The themes of the first edition were First Nation Voices and Living with Fire. Based on feedback, a popular section was the ‘Around the Campfire’ pages, which feature chats with a number of people.

The second edition will also have a focus on fire but coming from the human side of the story. That’s where I hope you might come in.

A Rifle Range on Maggs Mountain?

Many remote area walkers and fishers access the Central Plateau of Tasmania/lutruwita via the Mersey Forest and Maggs Roads, which lead to the trailheads for places like the Walls of Jerusalem, Arm River Track, Chalice Lake and Cathedral Mountain, etc.

There is a proposal to place a high powered rifle range on top of Maggs Mountain (900m), which is located above Lake Rowallan and across the valley from Clumner Bluff to the east and the February Plains to the west.

Meander Valley Council needs to decide whether to grant approval. You have until 5pm on Monday 29 November to put in a submission expressing your view on the proposal.

‘Atmospheric rivers’ threaten snow pack

We are all familiar with the impacts of climate change on snow in Australia. For instance, the snow pack has been in decline since 1957. And a report commissioned by the Victorian government suggests that the end of natural snow could be as close as a couple of decades.

One obvious phenomena we have seen often in recent years has been weather coming down from the tropics in north western Australia. These rains are often ‘snow killer’ events which can massively impact on the snow base.
