"It isn't that the alarm bells are about to ring. They already have & if these last 2 fires are not enough to scare the pants off you, I don't know what is." VIC's mountain forests are on the brink of collapse due to frequent bushfires & lack of regeneration support. www.abc.net.au/news/2025-06...

Alpine forests face collapse without urgent reforestation, say scientists
Bushfires and a lack of seed have created a "ticking time bomb" in Victoria's alpine and mountain ash forests, scientists are warning.
