Indeed. Still young trees the majority of them as well, dwarfed by the true old growth further south.
Sad thing is a lot of the 'veteran' trees with hollow butts & various features are ones having to be taken down due to liability issues post fire near arterial roads. We're trying to retain some with our climbing work, but geezus there are some sketchy climbs, forty metres plus trees propped up on 10% of their stem, heavy dense timbers around 1250kg/m. Standard 60m climbing lines, with a base tie we're out of rope getting to first decent limb on some.
All of the burn area is on karst landscape as well, which know the caves systems well from working in karst management, so systems up to 85m deep under some of the trees we're working in.
Working with some government department fallers as well, calm & gutsy characters, nerves of steel, we tend to retreat quite a distance & with haste when sending down big trees, these guys are dropping multi leg hollow butts & standing right near the stump as they implode!!
