I don't know why but my email to which Collette referred had been floating
about in the ether for a while before appearing on the list. It should have
been the second post in the thread, so when it eventually appeared, it was
out of sync with the rest of the discussion.  When I sent it, Collette had
not mentioned the target.

Mike:

I agree, but Collette had already defined the target, so one assumes some
level of investigation is warranted.

<<Well, the best practices regarding H annousum were probably derived to
try
and prevent its spread, but would have had nothing to do with risk
assessment / risk management with regard to property damage. In my
experience H annosum will trigger whole tree failure (root or but rot) and
occasionally trunk failure higher up in western hemlock. I guess you need
to
decide if the trees are worth enough as an amenity to spend time on
undertaking a more detailed assessment. If not, condemn them. If they are,
investigate in more detail and see what can be done. You may still end up
condemning them, but at least it will be with full knowledge rather than
guesswork.>>

From where I stand, the first consideration must be the target. Without a
significant target there cannot be a significant risk of significant harm.
Therefore, whether there is a high probability of failure or not, removal
of
the tree/s in the absence of a SIGNIFICANT TARGET is a waste of financial,
conservation and other resources unless there is some other overriding
management (perhaps silvicultural) reason to remove the trees.  So, the
question of whether "the trees are worth enough as an amenity to spend
time
on
undertaking a more detailed assessment" is premature in the absence of a
risk assessment (assessing risk of significant harm and not just
likelihood
of failure).
