Hi Philip
TreeCalc was updated about a year ago or so. You can now measure your Safety
Factors at any height above 1m. Have a look at the 'New Features' link on
the website. I cost one more credit though.
<<Treecalc is an awesome and under used tool...>>
Yes, it's an incredibly useful tool that can help with our likelihood of
failure decision-making. My research here has established Arborists
regularly give higher likelihood of failure decisions to trees that have
higher Safety Factors, and lower likelihood failure decisions to trees that
have lower Safety Factors. I'm pretty sure it's because when Arborists see
decay they think 'defect', see 'red', and increase their likelihood of
failure. As you know, TreeCalc can help recalibrate us with that part of our
decision-making in Detailed Assessments by showing this. It's one reason I
use TreeCalc in Validator and Basic Validator training. I thought it might
be too much for non-Arborist Basic Validator training, but without fail it's
been incredibly well received. Previously, even those with Basic Tree
Inspection training thought hollow trees, or trees with open cavities were
'defects' that need dealing with, when they're usually natural 'features'
with benefits. Showing them just how decayed a low H/D ratio tree can get
and still have a good Safety Factor is a revelation to them. It's often one
of the things they most enjoy.
