Not nearly as much damage as humans do to trees.

Hi Kim
YTBs do a lot of damage to trees, eg the allocasuarinas in the Arboretum.  They are trying to get at grubs that are in the trunk. We lost a lot of young trees because of that.

Male sat on the branch female continued to go around the tree

Wondering if she is in the early stages of  ring barking  to prevent goannas etc climbing to the nest as the tree is full of possible nest holes for future nesting  ?????????????????????
