I remember reading somewhere the reason Australia doesn't have woodpeckers is that we don't have trees which are suitable for them to hammer their bills into. Even the rainforest trees don't on the whole suit woodpeckers. I'm ready to be nay-sayed on this!!

Someone with more expertise than me should answer that.

What I have seen numerous times is that even low intensity burns can selectively cause trees with hollows in them to fall over, while having little apparent effect on younger trees.

Cheers, Chris.

About “if you just think of the loss of hollow trees, which happens as a result of ANY burning.” Yes that may well be true but can it also be the case that fires might increase the amount of available hollows in trees by damaging trees and allowing hollows to form in trees before the process of hollow formation would normally happen due to aging. Just asking……..

In the USA, I have heard many people speak about the importance of regular burning to improve and protect habitats. As an Australian, this has always felt odd to me, though recently I have read some material suggesting that in the USA this view is changing. In any case, the Australian landscape is very different, even if you just think about the extreme importance of hollows in old trees for wildlife, which is far more significant in Australia than elsewhere. And Australia doesn't have Woodpeckers! I also note that in the USA, many habitats we see have been hugely modified by Native American burning, so that there is perceived value in returning it to that state, not to any prehuman state. It is a complicated mess, but at least in Australia, if you just think of the loss of hollow trees, which happens as a result of ANY burning, (not to mention hazard tree removal!), it is easy to conclude that fire needs to be thought through very carefully and not controlled by knee-jerk reactions to particular events.

Cheers, Chris.

    ‘National’ in imitation of those Americans.  Some entertain the
    idea that some quite large wildfires should be allowed to burn
    unchecked to avoid really serious fires.  I don’t believe the
    ‘thinking’ in Australia has gone quite that far, but we are going
    to hear quite a lot about beneficial controlled fires, a subject
    complicated by the absence of a national agency with any
    responsibility in this area.
