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

[Philip van Wassenaer]

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,
