[CANUFNET] Appraisal of trees and estimating the age of trees

[Naomi Zurcher]

Hi MArk:

I am assuming these are urban trees and so I am wondering what knowing age would bring to these trees’ management. 

I have found that, within an urban setting, age is a fairly irrelevant issue since one can never pre-determine how a tree might respond to the grave difficulties it has to deal with, especially infrastructure such as paving and compacted substrate. The ability to break out of the coffin our street trees are routinely planted into and find enough resources to support growth will be of more relevance in whether the tree will live and maybe thrive.

Is there a registry of size, area and specie of tree that can identify the age of trees? I have 2 that I am dealing with, one is 90cm DBH (130 years old) and the other is 54cm DBH (80 years old ).
