states in part, that local arborists are refusing to allow their workers to
climb borer-weakened trees.

I'd be most grateful to hear from all of you regarding the standards or
"decision model" you use in this respect. I'm interested in all factors
that lead you to decide against remedial or removal work when there are
indications of structural damage or weakness.

Another case in point that occurred here recently involved a standing,
years-dead pine about 60 feet tall in a location inaccessible to
bucket-cranes (cherry-pickers) that had already begun to lose major limbs
to dry rot, some of which were already broken off and precariously
teetering on some lower branches that were still forty feet from the
ground.
