Widespread wildfires in early 2016 caused devastating damage across large areas of the Tasmanian World Heritage Area, including significant sections of vegetation which is not fire adapted, such as Pencil Pine forests.
At the time, and in follow up investigations, it became clear that increased fire risk due to climate change posed an existential threat to these vegetation types. Then additional research confirmed that there was a trend towards more extreme fire seasons. Some researchers suggested that we reached a ‘tipping point’ sometime around the year 2000 and that, 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”.
On the mainland, fires increased significantly from about the same time. There were major fires in the Victorian high country in 1998, 2002/3, 2006/7, 2013 and 2019/20. Fires are becoming more common and more intense across the Alps.
It turns out that something similar was happening around the country. Fire regimes around Australia shifted abruptly 20 years ago.
