Signs of dieback

Updated: Sep 3, 2020

How do you distinguish dieback from fire-kill?


Dieback is the product of infestation by wood-boring insects. These insects ring-bark affected trees, cutting off the flow of water to the leaves and sugars to the roots. Signs left by dieback remain for years, even decades, after death.


The ability to distinguish between dieback and other causes of death is a key element in ongoing research at ANU aimed at identifying the causes and response to snow-gum dieback. It's also a handy way for you to be sure you're seeing dieback and not the product of wildfire.


Help us by reporting dieback using our new app - Save A Snow Gum - available now on Google Play.
