[CANUFNET] Healthy tree definition

[Travis Kennedy]

Our Design and Construction standards touch briefly on "healthy" but add a number of other quality measurements to reinforce our intent:

Refer to section 02930 2.2 and 2.3  in Volume 5<http://www.edmonton.ca/city_government/documents/PermitsLicences/D_and_C_landscapsng.pdf>:  City of Edmonton Design and Construction Standards.

A design review comment that we like to make on submitted drawings from developers usually contains some or all of the wording below (this particular case is in reference to deciduous blvd. material):

"All trees to be high headed and exhibit a full and uniform crown, with a single dominant, well developed leader. Trees with broken or damaged or missing leaders will not be accepted. All plant material must conform to the City of Edmonton Design and Construction Standards."

This comment in combination with the standard helps prevent confusion about what is and isn't acceptable during our CCC / FAC inspection process.

There are various tree classification systems depending on intent.  For some purposes, it may be appropriate to require confirmation by a qualified person, subject to an authority's approval, that a healthy tree is not likely to degrade in health and functional attributes for at least the next 15 years.

Hello out there,
Is there an accepted or standard definition for the term "healthy tree"?  We would like to revise the wording for acceptable condition of trees at final inspection and do not want the health of a tree open to general interpretation.  Thanks.
