Hi There, Currently coming across lots of medium to mature aged sycamores with damage to the bark and cambium thus killing limbs and in more severe cases the whole tree. The tree that concerns me is mature with the cambium stripping away 5M up the main trunk and about 1/3rd of the circumference of the cambium. There is clear evidence of (what I presume to be) larvae damage on the deadwood falling with clear lines of feeding indicative of beetle damage. There is a lack of entrance or exit holes on this particular tree and I'm a little stumped as to a) what species is causing it and b) the extent of the damage that this species may cause. Any ideas on the pest or how I may find out more scientifically? Regards Richard TREE CANOPY CLIMB
