They saved the remaining grove of Wollemi Pine, thought to be extinct until it was rediscovered not too many years ago.
The tree losses are immense. It's not just that fire is normal for Australia, its the unprecedented size and ferocity of these fires. Where you may have a 'normal' fire season, the fires may burn a few thousand or hundred thousand hectares...these fires have burned MILLIONS of hectares.
In some areas there are no remaining unburnt areas in proximity for as far as the eye can see, so unless seed has somehow survived the catastrophic heat in some of the fires, regeneration will be a long time coming.
Hving said that however, a friend of mine said she heard a doco of a researcher who has been monitoring an area from the Black Saturday fires, 10 years ago, and where he would have thought there was no comeback, the bush has regenerated...so there is hope.

Australia's prehistoric Wollemi pine trees saved from bushfires in secret government mission
An ancient and endangered grove of pine trees thought to have stood tall among dinosaurs some 200 million years ago has been saved from the Australian bushfires in a covert firefighting mission.

New Euc trees sprout better after a fire than without from what I've seen here in the States - at least up to some certain temperature and duration of burn. "scarification" (?)
Not the best video on it but what I found and refers to Australia specifically.

Indeed that is the case...but some of the fires were catastrophic, the heat burned eveything but trunks. Just sticks left, not a scaffold branch to be seen..the heat was far beyond the 'normal' seasonal type of bushfire.
I would be very keen to go back to some of the places i worked on my deployment, in like five, ten years time.

wonder if they could regenerate with this dort of methodology
