BostonBull,
I can't say for sure how much can be attributed to the lac balsam. It is a white ash growing in a very wide tree lawn. There is irrigation on the property so the tree does not suffer from drought stress.
Guy,
The wound on the tree faces west.
Did I mention that the wound was caused by a car crashing into it. This is the tree that stopped the car, the tree next to it, also a white ash but a few dbh " 's smaller, was damaged similarly.
