[CANUFNET] 10th Guide to Plant Appraisal - Dr. Dunster reveals the truth

[Gerard .]

Hi Philip,
Yes, I agree with you and with Julian on this, the tenth is a little sketchy.
I think there are some excellent parts to the tenth, like functional contribution factor instead of location, but the details mentioned by Dr. Dunster in his review must be resolved.
I have already been using the tenth for a few valuations, but still have the trusty old ninth in my hip pocket!
Lol.

Subject: [CANUFNET] 10th Guide to Plant Appraisal - Dr. Dunster reveals the truth

Hello,

Some of you may be aware of the esoteric practice of tree and plant appraisal. If you are, you may be aware of the recent publication of the 10th CTLA Guide for Plant Appraisal. Still fewer of you will likely have had the chance to get the first publication before it was recalled. We now await a "corrected" version. If you did get the document, you need a corrigendum to try to use it at this time.

If you have read the whole document and "figured it out", kudos to you.

In the midst of this uncertainty many professionals have chosen to continue to use the tried and true methods in the 9th Edition. The most common methods have been vetted through Canadian legal tests and have been fully accepted. Since the 10th is brand new and introduces changes to almost all former practices, introduces new ones, and even abandons some, their worthiness in a legal framework is unknown.

Dr. Julian Dunster recently wrote an excellent review of the 10th and it was published in Tree Service Canada. In this thorough and extensive review, Julian shares with the readers his poignant concerns about many aspects of the document as well as pointing the reader to those areas that are valuable and help advance plant appraisal. His review is attached.

If you know everything about this topic, or very little but are intrigued by where the practice of plant appraisal may be headed, this is an interesting and important read.

Thanks go to Dr. Dunster for taking the time and making the effort to be open and honest in his review.

I would welcome any and all discussion from everyone on this subject. This publication (10th Guide) could have a significant effect on Urban Forestry across Canada and it might not be positive... Is anyone concerned? Is it time that we have a Canadian guide to plant appraisal?

Sincerely,
