<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I suggest that instead of focusing on the tree health at final
inspection, that you change your contracts to state that all trees must be
inspected and approved by city staff prior to planting. Ideally you could
go to the nursery with your contractor and pick out the trees you want.
It can be difficult to get the contractor to make any changes at final
inspection.<o:p></o:p></span></p>

supply the trees to the landscaping contractor to ensure quality. Having
a good quality tree to start with doesn’t guarantee that it will still be
healthy by the time you have final inspection, but it should help.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-CA 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 lang=EN-CA 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 lang=EN-CA style='color:black'> <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-CA 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 lang=EN-CA style='color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-CA 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 lang=EN-CA 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 lang=EN-CA 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>
