<DIV class=Section1>
<P class=MsoNormal><SPAN style="COLOR: black">With regard to Travis’ comments,
it seems to me that this wording leaves it completely open to whatever
subjective interpretation your inspectors may have on any particular day,
with no recourse whatsoever for the contractors or nurseries that have their
trees rejected. You are basically saying that a tree must conform to your
standards, whatever they may be, right or wrong. <o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">In point of fact, trees are not
normally high headed, and must be pruned that way in the nursery. Such pruning
is clearly detrimental to the health of the tree, and in most cases, stunts the
growth, reduces taper and trunk strength, and invites disease and poor
compartmentalization, which can lead to trunk cracks, sunscald and several other
defects that I can think of. This is all well researched and documented in Alex
Shigo’s book ‘A New Tree Biology” 1989 and in “Modern Arboriculture.” 1990.
Other researchers such as Gilman have since written excellent books on the topic
of pruning and pruning trees for urban areas in the nursery, which have been
universally accepted by most of the rest of North America and the world.
<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black"> <o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">And what of trees that do not
normally have a central leader in the Edmonton area? Trees like Green Ash,
Mayday, Schubert, Amur Cherry and Ornamental Crabapples very rarely
possess a “single dominant, well developed leader.” I can only imagine that very
few otherwise healthy trees of these varieties survive your inspection
process!<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black"><o:p> </o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">Even if any particular Urban
Forestry department actually knew what a “healthy tree” was and could specify
this in a way that was “not open to interpretation”, there is no guarantee that
picking a tree simply on the basis of “good” form will guarantee future good
health, especially in a place where trees are notoriously difficult to grow,
such as the Western Prairies. Planting methods are the single biggest factor
influencing the success of a tree. And while you are perfectly right not
to accept a tree with obvious signs of abuse such as scrapes and broken
branches, we continue to plant the healthiest of trees in the worst of places
and blame the tree when it dies. Trees need room to grow both above and below
the ground to sustain themselves, and usually have neither in most Urban Areas
in the world today.<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">Fixating on a tree’s form,
especially when the form is entirely unnatural to the species or variety,
certainly should never be considered the only attribute of potential
good health!<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN style="COLOR: black">We obviously need to rethink the
whole notion of “tree health” when Urban Areas are still in the design process.
I believe it is possible to shape cities to conform to nature, but nature
cannot be retrofitted to fit our cities, if our cities are to be
sustainable.<o:p></o:p></SPAN></P>
