Snow Gums (Eucalyptus pauciflora) are the classic alpine tree of the High Country, generally growing at heights between 1,300 and 1,800 metres asl. Anyone who has visited the Australian High Country will know – and probably love – these trees.
In recent decades, wildfire has been devastating huge areas of the Snow Gum forests, with significant fires in the Victorian High Country in 1998, 2002/3, 2006/7, 2013 and 2019/20. More than 90% of Snow Gum habitat has been burnt at least once in the last 20 years.
The species can survive fire. However, climate change driven fire seasons are leading to more frequent fire, which is causing more death of trees and changes to forest structure. In some instances, localised collapse of Snow Gum woodlands is now being observed. As climate scientist Michael Mann describes it, we are now seeing climate change play out in real time.
We must ask whether we are now seeing the start of the collapse of Snow Gum woodlands, one of Victoria’s iconic vegetation communities.
