What's Eating The Tree?
...And can anything be done to stop it? The tree is a Sycamore. Hoping I've not left things too late...
All sorts of things in there Adrian - you can see woodworm (beetle) holes and then the larger masses could also be from dead-wood feeding beetles and other critters, the rot aide by fungi, woodlice etc...
But it does seem to be confined to the dead wood in the centre - the rest looks healthy, and there is no reason why the rot/infection will spread to healthy tissue any time soon. As any tree ages, the centre often hollows out through rot, leaving a cylinder of living wood, which is remarkably stable (akin to the hollow tubes of scaffold poles)
Thanks for the response Chris!
