Here's what the natural forest in the area looks like. I'd say from the blackened trunks that a controlled burn has been done around here. Controlled or hazard reduction burning is conducted during the cooler months to reduce fuel buildup and decrease the likelihood of serious hotter fires. It's a contentious issue. Conservationists worry about it's affect on wildlife even though our forests need fire to germinate seed. Every time we have big fires, like the recent devastating fires in Victoria, the debate heats up again.
From Fire-stick Farming by Mark O'Connor
"To grow flowers in Blackheath, Australia,
set fire to your field. Let flame
singe the delicate dust-seeds
of native shrubs. Soon they sprout,
a thin patchwork of tufts, nameless and mixed,
on ground bare, as if hoed."
