Please track 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.

According to work published in the Resort Roundup winter 2019 edition (produced by the NSW government), ‘reduced snowfall, high summer temperatures such as January 2019 where temperatures at Thredbo top station were 4.4oC above average, and a reduction in autumn rainfall mean that snow gums are under much greater moisture stress than in the past.’ This means that larger beetle populations are causing more frequent dieback of some snow gum trees.

The SOS Snowgum program is asking people to log instances of dieback in mountain areas.

2020. It’s been fun. Let’s move on.

Wow. What a year. Crazy summer fires. Covid lockdowns. Terrible winter snow pack, but also some incredible snow storms. Lots of fighting over our mountains, including the endless culture war argument about horses. Kind of glad it’s almost at an end.

We all know the story: a dry winter and spring led to a horror summer, with massive fires across the eastern Victorian high country, Snowy Mountains and Brindabellas. Luckily Tasmania got off easy last summer.

Then the lockdown(s), which hit mountain and valley towns in Victoria especially hard, isolated Tasmania, and closed the NSW/ Victorian border. The economic impacts of these events will last for a long time.

And then there were the ongoing arguments about how to treat our mountains. It felt like issues were widespread this year. Here’s a few of them:

Finding hope among the old trees

I don’t know about you, but my wanders in the mountains are often dominated by grief as I see places I love burnt beyond recognition. I’ve spent way too much time looking at burnt forests lately (for instance the Tabletop fire), and the realisation that as I get older, the forests are getting younger has been hard to accept.

More than 90% of snow gum woodland in Victoria has burnt at least once in the last 20 years, and we are down to a fragment of remaining old mountain forests (estimates are that we only have 0.47% of old growth alpine ash left in Victoria). Most people who are paying attention will see what’s going on, and experiencing solastalgia (the distress specifically caused by environmental change and climate change) is both natural and normal. But it can be hard to stay positive in the face of grinding and overwhelming change. And many of us, especially if we live in the bush or mountains, hold fear about the ever more intense fire seasons.

But there is so much wonderful country that remains, and we know that, given time, alpine ash and snow gum forests will recover (if we can keep the fires out until they mature).

Our best chance to get climate action in Victoria

Anyone who is paying attention knows that climate change poses an existential threat to the mountains we love so much. From more intense fire seasons to less snowpack and less water in the rivers, change is coming, and we need to act now as a global community before we become locked in to catastrophic climate change.

In Victoria, where we still mostly rely on dirty coal to make our electricity, we have a chance to steer our economy towards clean, renewable energy. That chance comes from the fact that the Victorian government soon needs to set emission reduction targets (ERTs) for the years 2025 and 2030.

As part of one last push to influence the government, we hope you will join this simple ‘selfie’ action, and tell the government you want to see serious climate action.

Mini wind turbines to power off-grid communications – and more?

Mountain communities usually rely on long underground or above ground power lines to connect them to electricity supply. These can be cut or damaged by bushfire and winter conditions. Stand alone micro power grids powered by renewables could well be the climate-friendly solution to this problem.

Renew Economy reports that:

‘The Australian Renewable Energy Agency will provide $341,990 in grant funding to support the development of mini wind turbines designed to power off-grid telecommunications towers and remote applications’. When combined with storage batteries, these could also provide electricity to ski resorts and other remote and mountain towns.

Federal government rejects key recommendation from Royal Commission

Australia’s fires over the summer of 2019/20 were unprecedented in scale and level of destruction. Fuelled by climate change, the hottest and driest year ever recorded resulted in fires that burned through more than 17 million hectares, killed up to 3 billion animals, and affected nearly 80% of Australians. This included the tragic loss of over 450 lives from the fires and smoke.

Aerial firefighting capacity – planes and helicopters – are an essential component of Australia’s ability to respond to bushfires. This was demonstrated in the 2019-2020 bushfire season, when an unprecedented use of aircraft occurred. However last summer also showed that we simply don’t have enough aircraft to fight fires in a bad season. This puts landscapes, people, towns and houses, and fire fighters at risk.

The recent Bushfire Royal Commission report recommended the creation of a national publicly-owned aerial firefighting fleet, which can then be allocated to the states “according to greatest national need”.

‘State of the Climate 2020’ – what does it mean for mountain environments?

The Bureau of Meteorology and CSIRO have just released their updated ”State of the Climate’ report. This is produced every two years and provides an update on what is happening with the latest climate science. As in previous report’s, the impacts of climate change on the Australian landscape are clear. There are also some specific details for people concerned about mountain environments.

Public Seminar – Snow-gum dieback and forest decline

Many people know the story of the Pine beetle which has been devastating huge areas of forest across North America because of climate change. There is a similar scenario emerging in Australia’s mountain forests, although it is much less known.

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.

On December 10, Dr Matthew Brookhouse, Project leader of the SOSnowgum program, will deliver a public online seminar on snow-gum dieback. The seminar will focus on recognition of dieback, the research being done into dieback, and a citizen-science program that is providing information on the spread of dieback.

A chat with Jakob Kennedy

Jakob Kennedy is a content producer and nature enthusiast. He is currently involved in the development of a film called Awaken, which follows adventurers on three continents as they come to terms with the growing impact of climate change on the places they love. 

Jakob says “other than my clear love for snowboarding, it is nature, the experiences she provides and the inevitable lessons that are the reason I’m still doing this. So to be involved with a project that honours the value of these moments, by raising awareness to the importance of maintaining said environment, is a sure highlight in my career.

We only get one world and we only get one life do our best to care for it”.

The full version of the film will be released this January. You can see the trailer here.

Mountain Journal caught up with Jakob to find out about what the project and what inspires him. You can read the interview here.

Stand with bushfire survivors for climate action

Bushfires devastated huge areas of mountain country last summer – across the eastern Alps in Victoria and the northern Snowy Mountains in NSW. These fires triggered three government inquiries – all of which identified climate change as being a key factor in the scale of the fires.

Now the Bushfire Royal Commission is due to release its final report. A key question will be whether the Commission recommends that Australia act decisively to reduce it’s contribution to global heating. Bushfire Survivors for Climate Action (BSCA)  is asking you to stand with us on climate change to highlight the need for the federal government to act.

Fires hitting mountain environments around the world

Last summer, large sections of the mountains of New South Wales, Victoria and ACT were hammered by bushfire. The Emergency Leaders for Climate Action noted that: ‘Australia’s Black Summer fires over 2019 and 2020 were unprecedented in scale and levels of destruction’. 

The same terrible fires have been burning environments across the northern hemisphere through their summer. For instance, Colorado has seen its largest ever fires. Fires have burnt on Mount Kilimanjaro, Africa’s tallest mountain, and in the north east of the USA, a region that rarely burns. One fire chief in Maine said “this was a whole new kind of fire, this is the stuff you see out west.”

And the same forces are at play everywhere: climate change is making fire seasons more intense. The world has warmed as a result of human activity and now all fire events occur in a warmer environment. Thankfully this awareness is now becoming part of the mainstream debate.

ANU launches centre for early fire detection & suppression

Last summer, 1,507,895 ha of Victoria was burnt, much of it in the remote mountains of the Alps and East Gippsland. Almost every significant fire in Victoria during the 2019–20 season was as a result of lightning strike. 

Many of these started after storms moved across East Gippsland and the Alps on November 21 and December 31. Forest Fire Management crews swung into action and many of the fires were quickly put out. Aerial bombing dealt with others. In the 2019/20 fire season, state government FFMV crews suppressed 89% of all new ignitions with aggressive ‘first attack’ techniques. But there were simply too many lightning strikes, and some grew into massive blazes, including the fires that went on to devastate the forests and landscapes of East Gippsland in coming weeks.

It is clear that we need additional air capacity to get on top of these small fires before they become blazes. We also need more career remote area firefighters. Victoria should also follow the lead of NSW and TAS and establish a volunteer remote area firefighting force. In recent years, the NSW teams have able to keep 90% of the fires they attended contained to less than 10 hectares in size.

But fire seasons will continue to get longer and more intense because of climate change. We need all the help we can get to stop these lightning caused fires before they turn into blazes. This new development could deliver some useful help:
