<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think that you cannot discount the species value because of EAB but you may need to discount the value of the tree by the cost of preventative treatments over a reasonable amount of years. For example a $5,000 ash tree should perhaps
be devalued by the cost of Treeazin treatments over ten years. If treatments cost $300/2years, the tree's value may be $3,500. <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I devalued a birch tree that I assessed to account for cost of treatment to address a bronze birch borer infestation. Very similar. Although the report didn't see a court of law it was accepted by the insurance companies. <o:p></o:p></p>

<p class="MsoNormal">If there were no treatment options for EAB, it would be a different situation i think.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-CA">It would be interesting to see if there is some consensus about how to proceed; should we start discounting the species ratings because ‘all ash are doomed’?
Or should we still consider each tree on its individual merits and outwardly-visible condition, even though it may already be infested and not yet showing symptoms? How do we account for the fact that many (if not most) ash trees will become liabilities once
infested/dead? <o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-CA">Personally, I am somewhat hesitant to start discounting still-healthy trees because of susceptibility to a pest (after all, many elms have survived), but it is
generally accepted that we will lose most of our urban ash trees, and this may be fair to consider that when assessing value.<o:p></o:p></span></p>
