Some interesting thoughts here.

Those little dots; most arborists I know do not have the equipment or
expertise to to locate trees with any precision, nor the GIS software to
plot them.  If an arborist is using a plan created by a surveyor than
surely the arborist must locate and plot not the tree, but the entire
trunk diameter or root collar/trunk flare with the same accuracy and
precision.

Certified tree expert; what exactly is this?  ISA Certified Arborist? 
Self-taught?  College-educated with an emphasis on climbing?  Two days of
TRAQ?

Does a certified tree expert mean somebody with the knowledge, training
and experience to perform the work at an expert level?  In the case of
tree preservation reports this would surely mean that the tree expert
would require not only education about trees but also construction
techniques etc.  Further how can the arborist be expected to create a TPP
without speaking with the architect, landscape architect, constructor and
excavator?
