Wayne, what is your point?  "*The problem remains that there is no way to
determine for certain when the tree will fail, if ever, depending upon a
constantly-changing, imponderably complex context*."  Shall we do
nothing?
Shall we cut every tree?  Shall we use our knowledge, training, and
experience?  Shall we learn and move assessments forward?  Perhaps you
believe that we are incapable of working with uncertainty?

 Perhaps you can provide a better strategy we can all learn from and
critique.

If tree assessment following storms means looking for leaners, cracks
in
the soil (usually on the side opposite the lean), and raised soil on
one
side of the tree, the tree may be terminally weakened. There have been
cases where the remaining root system was strong enough to hold that
position long enough for new growth to continue to add a component of
resistance, allowing the tree to remain for several years. The problem
is,
the tree remains out of balance, and as the canopy continues to grow,
more
weight is added to a longer moment-arm, increasing the tension which
the
remaining damaged root system and any new root growth must resist. The
problem remains that there is no way to determine for certain when the
tree
will fail, if ever, depending upon a constantly-changing, imponderably
complex context.

This might interest those of you who carry out tree risk assessments
at
schools or colleges

We've just uploaded and shared a new Tree Risk-Benefit Management
Strategy
template for schools or colleges in the Landowner section of the Risk
Management page on our website.

https://validtreerisk.help/Risk-Management

This work was prompted by a Validator asking for some client
guidance.
As
with the other Strategies and publications, we've waived copyright,
and
it's
shared under a creative commons licence.

The difference between the Landowner & School Strategies is the size
of
land
and number of staff.

Landowner
Many staff who spend a lot of time working outside have been trained
as
Basic Validators.  Like the University of Dundee.

School
Usually, one or two caretakers who spend some time working outside
and
haven't been trained as Basic Validators.  When they're outside, they
carry
out Passive Assessment by keeping an eye out for Obvious Tree Risk
Features;
particularly after storms.

Cheers
