Not all will agree. I think there has been tremendous efforts, by significant arborists, professionals, and groups, to address many concerns that were in previous editions.</div><div dir="auto">Not all professionals endorse the 10th, but many professionals do. When TRAQ first came out, there were many critics, and still are. Many didnt think we should move away from numerical quantifications of different variables. They may be right!</div><div dir="auto"><br></div><div dir="auto">Reading through the Nova Scotia court case (from the site Michael pointed to), it reiterates the need to reconcile your opinion on the method you chose. Perhaps you have chosen a few methods, and reached to something that can be agreeable.</div><div dir="auto">Back to one of the points earlier, with TFM or TFT and forested or wooded areas, it may not be appropriate, it depends on the usage, functionality and utility.</div><div dir="auto"><br></div><div dir="auto">One thing is for sure, appraising trees is not for everyone, and involves a considerable amount of experience and practice.</div><div dir="auto"><br></div><div dir="auto">For the Town I work for near Alliston, we will be moving to an aggregate caliper, with depreciation for compensation in planning and engineering. It is functional, and easy to calculate. For larger wooded areas, we may adopt area calculations, similar to what Guelph has in their technical manual. For bylaw concerns, and wrongful removals, we may keep with TFT for proper replacement costs and to determine the value on the day (if possible).</div><div dir="auto"><br></div><div dir="auto">Just yesterday, a farmer decided he didn't like the row of 15 to 20 70foot tall silver maples along one of our lines.

<div dir="ltr">
<div>Agreed. Previous editions seemed to mostly just fine-tune earlier editions. The 10th is more of a wholesale rewrite.</div>
<div><br>
</div>
<div>My 2 cents: just because someone has come up with a new approach to calculating Pi, that doesn't make all the other ways wrong. You still get Pi. It sounds like that's basically what the 3rd summary statement, quoted in Michael's message, is saying.</div>

Indeed the 10th edition is problematic. There has been a second revision or<br>
edition and now it is my understanding that some of the work sheets have<br>
been corrected and need to be downloaded.<br>
I will not use it till it is right.<br>

One day after I said TFM is obsolete and replaced by TFT I see this website:<br>
<a rel="noreferrer" href="https://10thguideforplantappraisal.info/">https://10thguideforplantappraisal.info/</a><br>
<br>
A summary paragraph:<br>
<br>
The summary position of this group is:<br>
<br>
The undersigned individual plant appraisal practitioners do not accept the<br>
10th Edition, in its 2020 form, as a generally accepted[1], complete[2], or<br>
exclusive[3] expression of best practice in plant appraisal."<br>
<br>
<br>
<br>
[1] 10th Ed. is not generally accepted. General acceptance is created<br>
through extensive experience and use. General acceptance is not created by<br>
mere publication of new and untested methods and techniques. General<br>
acceptance is not created by fiat.<br>
<br>
[2] 10th Ed. is not a complete expression of practice or best practice and<br>
is inadequate, by itself, to guide practice.<br>
<br>
[3] 10th Ed. is not an expression of practice or best practice to the<br>
exclusion of any other practice guidance.<br>
<br>
Something to think about if you are doing Tree Appraisal<br>
<br>
