Over the past couple of years, various people have been tracking the localised loss of snow gums in the Victorian high country due to more frequent and intense fires. We know that snow gums are, like many Australian trees, fire adapted. But we also know that they enjoy a decent gap between fires and that with climate change already increasing the frequency and intensity of fires, that we are starting to see localised loss (‘collapse’) of these woodland communities.
Given my connection to the Mt Hotham/ Dinner Plain/ Dargo High Plains area, initial investigations started there. Sadly, there is no shortage of localised collapse in that area, where repeat fires have killed off both parent trees and seedling regrowth. But through advertising via Mountain Journal and the Snow Gum citizen science facebook page, we started to get reports from across the Victorian Alps, from Mt Clear in the ranges south west of Howitt to Mt Pinnibar, in the far north east of the state. Thanks to everyone who contributed content.
Having greater numbers of people looking has given a wider sense of where loss is happening. But it has also given us an understanding that, in many areas, the trees are now starting to come back.
This is wonderful news.
