Even though I have tried to carefully read all related posts and several
news reports, I'm having a devil of a time teasing out specifics. Some
journalists seem to be especially lax in providing details.

If we believe Henry Geiger's cautionary statement: "The more you generalise
about a population, the less you know about any individual in that
population," it is apparent that generalisations can be misleading.

I would like to know if any of the fellings were justified, and for what
reasons.

I would like to know if any of the fellings were unjustified, and for what
reasons.

That is, while I understand and embrace the emotional reasons for wanting
to keep trees, I believe that it is the professional responsibility of
those of us in the profession (in my case, *was*) to continue to hone our
skills with respect to analysing potentially hazardous conditions as well
as evaluating all relevant factors in determining tree stability. Just as
overzealous and premature removals should not be based on emotion or
selfish motivations, I likewise believe that it is our responsibility to be
honest and scientific with respect to tree stability and instability. I
also believe that some danger is inherent in trees, even those which cannot
be determined to be potentially hazardous--I am confining my investigations
to the *extreme* cases. Unfortunately, my study as turned up a surprising
(to me) number of cases where tree instability was glaringly obvious before
the failure, and frequently following actual inspections. This cannot be
good for the profession.

I am also aware of the great burden this places on the tree-related
professions, and the great difficulty of drawing the line between stable
and unstable. Unfortunately, some apparently believe the solution is to
evade that responsibility, and I believe that such an attitude (not to
mention the practise of evasion) is unprofessional, and sometimes downright
dishonest. (Mind you, I get this impression largely from my investigations
in the US. Some of these investigations are based on actual inspections;
others are based on reports, photographs, and other on-line *evidence*, not
testimony--which is often quite wrong. Such conclusions always must be
tentative, but the latter evidence, when I rely upon it is always quite
obvious.)
