Mountain Ash (Eucalyptus regnans) is the ‘signature’ tree of the damp montane forests of south eastern Australia. Generally growing in temperate areas receiving over 1,200 millimetres rainfall a year on deep loam soils, this species is the tallest flowering plant on earth.
They have been heavily logged for well over a century, and massive areas have been burnt in wildfire. Now climate change and extreme fragmentation of habitat is driving Mountain ash forest in south-eastern Australia towards ‘almost certain collapse in the next 50 years’, according to an assessment by researchers from the ANU.
The key message in this research is:
Researchers “modelled 39 different scenarios and found there was a 92 to 99.99% chance of collapse of the mountain ash forest in Victoria’s Central Highlands by 2067”.
It is also important to understand that there is still a “critical window where we can act to prevent the loss of the mountain ash forest ecosystem”.
