 SC Tony I'm not so sure there's a realtionship between stem
diameter and anchorage so much as large stem diameter being more
resistant to overturning (even if it was a cut log with no
anchorage) or frature (even if hollow).

True, however you would expect the larger the diameter of the trunk,
that the structural anchoring roots would be larger too. Thus possibly
being less resistant to decay than smaller roots on smaller diameter
dead trees.

Obviously this has to take into account the original cause of
mortality, in which root decay fungi like armillaria will influence
stability. Also wind exposure, species, topography and soil type and
depth will be a factor.
