<p>Bonjour Bruno</p>
<p>I think you are looking for a suggested health rating. Using the
word target may be confusing as that is usually reserved for the
target of concern in the event of failure. I am not sure there is
such a thing as a suggested health rating that can be equitably
applied in all cases. Many of us use a very broad scheme: Good (no
obvious problems of concern), Fair (some problems but none of them
too serious right now, but a downward trend is likely), and Poor
(obvious problems that the tree will not overcome and mortality is
likely sooner not later). I try to avoid splitting it down into
really fine components because they never ever work in every
situation, most of it is very subjective, and it can change quite
rapidly. I really don't know what the percentage figures would
tell you (I am assuming that you did not mean percentage of canopy
cover). With climate change (prolonged summer drought and heat
domes year after year) overall tree health in urban and rural
areas is trending downwards very rapidly on the west coast,
especially on Vancouver Island. <br>
