Post fire recovery in Kosciuszko National Park

Since the fires of last summer there has been a lot of conservation recovery and rehabilitation work carried out in and around Kosciuszko National Park. Recently the NSW National Parks and Wildlife Service (NPWS) hosted an update on the work that has been done, through a forum called Conservation in Action, which was held in Tumut.

As we know, a lot of Kosciuszko National Park was heavily impacted by the fires. Dan Nicholls, from the NPWS gave an outline of some of the work carried out since then, which includes:

Dargo High Plains subjected to intensive logging

The Dargo High Plains are a much loved part of the Victorian high country, with extensive open plains surrounded by eucalypt forests, much of which is dominated by Alpine Ash (Eucalyptus delegatensis). Alpine Ash is one of the iconic trees of the Victorian mountains, where it is widespread and often dominant in grassy or wet subalpine forests, in deep fertile soil, often on slopes, and where it commonly forms pure stands. In Victoria it occurs at altitudes between 900 and 1,500 m (3,000 and 4,900 ft). The high points of the Dargo High Plains sit roughly between 1,300 and 1,500 metres above sea level.

Only 0.47% of old growth Alpine Ash still exists in the forests of the Central Highlands. In the mountain ranges of north eastern Victoria and East Gippsland, old growth Ash is now rare, and ‘tens of thousands’ of hectares of forest are on the verge of ecological collapse.

Sections of the Plains have burnt several times in recent years, including the summer of 2018/19. Considerable sections of the Plains Ash forests have been logged in the past. Now, the state government has scheduled a number of logging coupes of long unburnt forest, which threatens to devastate the fringes of the high plains.

The logging program in the High Plains area appears to include roading through the Alpine National Park to access the coupes on the east side of the plateau.

Dead forests making bushfires worse

We know that climate change is making fire seasons longer and more intense. This is happening globally. It has enormous implications for the landscapes that we love, how we prepare for and fight fires, and even how we live in fire prone areas.

These fires are transforming the landscapes we know and love. Anyone who has driven out of Jindabyne into the Snowy Mountains, or Mt Beauty towards the Bogong High Plains knows what I am talking about – endless walls of grey, dead trees. Only 0.47% of old growth Alpine Ash still exists in Victoria. This has huge implications for the aesthetics of our mountain areas, and significant ecological implications.

Increased fire frequency could see mountain forests like Alpine Ash replaced by wattle woodlands. As recently noted by Brett McNamara, the manager of Namadgi National Park:

Recovery happens but it is “tainted with a sense of what does the future hold for us if we are to experience fire again and again with such intensity. This is where the question is unanswered. What these mountains will look like well into the future?”

The huge volumes of dead trees from previous fires also creates a lot of fuel that is already dry and hence ready to burn in future fires. What are the implications of this for our fire fighting and land management efforts?

Subalpine forests struggle to recover after 2019-20 bushfires

The Bushfire Recovery Project, led by five scientists, is tracking forest regrowth in NSW and Victoria after last summer’s fires, using data gathered by citizen scientists.

Their report has found that while low elevation forests on the NSW south coast appear to be recovering well, forests in some subalpine areas ‘near Mount Kosciuszko and in Victoria’s East Gippsland region are struggling to recover from the 2019-20 bushfires’.

This is consistent with everything we already know about the impact of climate driven fire seasons on the higher elevation Alpine Ash forests and Snow Gum woodlands.

Increase in lightning strikes expected to ignite more wildfires

Lightning strikes are one of the main causes of wildfire in Australia. As the planet’s temperature warms, the frequency of lightning strikes is expected to grow with it.

Currently, lightning strikes the earth’s surface nearly eight million times a day. This number is expected to ‘dramatically increase’ as global temperatures rise, according to a study published by Science. The U.S., for example, could experience a 50% increase in the number of lightning strikes by the end of the century, if greenhouse gas emissions are not curbed.

This increase is already being felt in Australia and has implications for how we plan for, and fight fire. Because they start from a single point, lightning caused fires are initially small and can be easily contained before they turn into blazes, if there are ground crews or planes or helicopters available. As was shown by last summer’s fires, in a bad season, we simply don’t have enough resources to do this.

A new year. The old threats continue.

Well, we’re on the other side of New Year. Phew. I hope that you’re enjoying some good mountain time over summer and getting a recharge. There’s lots to do this year.

There are a range of environmental issues that have been bubbling away over the last year, and each of them have campaigns which could use some extra support if you have the time or resources. Here’s a sample of what’s going on.

One year on from the DEC 31 fires

In late November 2019, fires started in East Gippsland as a result of lightning strikes. As noted by Peter Gardner, many of these went on to become major blazes. November 21 was a Code Red Day, causing fires across the state. On December 30, fires tore through the township of Goongerah in East Gippsland. By 30 December 2019, the fires started in November had grown into three active fires in East Gippsland with a combined area of more than 130,000 hectares, and another in the north-east of the state near Walwa, which was heading south-east towards Cudgewa.

And on new year’s eve, lightning storms passed across the state and started another set of fires across the Victorian mountains, and fire season came to the Alps with a vengeance.

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).

Federal government accepts need for publicly owned air fleet

Since last summer, there has been a long public conversation about how we can increase our ability to fight bush fires. While this has covered everything from the role of fuel reduction burning, the impact of climate change, and the question of Cultural Burning, another important aspect has been the role of planes and helicopters in fighting fire.

There is a recent – and significant – development in this debate.

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.
