Wasn t referring to this cavity being filled with decay and suggested it could be quantified by appropriate person. I was referring to a silver maple's future often involves contact with a hack that will perform internodal cuts, flush cuts, drop wood on the root crown, etc. because this is what they do. And this is what causes decay. And these are the trees they most often target, not just because they overgrow but also because they often are planted too near targets (homes, play areas,etc.), and also as they give the appearance of improving by this injurious treatment by triggering adventitious sprouts out of the callus immediately.
The HO ofcourse has no idea that decay causing organisms have been granted full access to their tree by this mass breach of the tree's defense system. This is what I meant by "filling" the tree with decay.
Yeah, I guess your site wasn t all that good in retrospect.
