To have a look at the back of every tree that could fall onto the highway could bankrupt the state government.

Really?

OK, you have an unusual situation of low population density and long tree lined roads but even so your conclusion that walk by rather than drive by tree assessment could "bankrupt the Government" seems like a bit of a stretch, to me.

Hey, just thought of something.

What about Google Earth "Fly By" assessments?

Hi David

There's no belief that they know the whole story.  The design is that
one side of paper will be scanned at speed.

The context is Tasmania's Depart of State Growth has about 3700 miles
of roads and millions of trees.  Trees provide many benefits that they
need, and the overall risk from tree failure is extremely low.  Given
this, to have a look at the back of every tree that could fall onto
the highway is not reasonable, proportionate, or reasonably
practicable tree risk-benefit management.  To do so might bankrupt the
state government, or mean they couldn't provide many other important
services.  The design is that they're trying to find 'obvious
defects'.  To try and find defects that aren't obvious by looking at
the back of each tree would be grossly disproportionate to the likely
reduction in overall risk.
