@yaorenliu thank you, no I don't think so. The trees tend to respond to all sorts of stressors and the bark can be very colourful. I guess it could have been a response to damage from native mammals or insects or other meterological stresses.
@randystreat All those 'shrubs' you can see? They're all trees. Its both a vast landscape so they look small, and tough growing conditions so they don't grow huge.
