Here is an observation of Bruce Hagen's nomenclature.
For those of you who dont know him or about him he is a Registered Professional Forester (takes more education to get that, than it does to get a medical degree)
Bruce has contributed an incredible amount to our field but I have an issue with two points he makes in his article titled:
Forest Health-An Emerging Issue. Arborist News Feb 2005 Volume14 Number 1
On page 25 he states:
Quote: Under normal (endemic) conditions, bark beetles cause significant but scattered losses. They "harvest" old (overmature), suppressed (overtopped), diseased, and stressed trees. End Quote.
Does any one see anything wrong with this statement?
Just wondering if a tree can be "overmature" or if a tree can be "overtopped"

Frans, Overmature is a recognized term indicating an old tree that has entered a natural decline. Ratio of dynamic mass to heartwood/dead tissues is small.
Overtopped is a forestry term meaning a tree growing in the shadow of a larger tree(s). The larger tree(s) outcompetes the understory/dominated tree-making it a prime candidate for beetles since it may have reduced vigor and vitality.

Well, from a laymans point of view (mine) I guess I agree with the technical foresters definition of 'overtopped' meaning an understory tree.
But the term Overmature I dont agree with any definition they may use. Either a tree is mature or is is'nt. From a Foresters point of view a tree may become 'overmature' when it is no longer harvestable. but the article is/was written in an Arborist's magazine. And in that sense the word does'nt make any sense to me.
Go figure

Frans, Here is the definition from the American Society of Consulting Arborists.-Overmature: Tree or stand that has passed the age of maturity where the rate of growth has diminished and the trees are weakened.

I didn't like "overmature" the first time I read it either but it is a legitimate arboricultural term that DOES fit a particular stage of life of a tree. /forum/images/graemlins/smirk.gif

Contrary to idealists belief, all trees are mortal and liable to death, with exception of the Bristle Cone Pine, White Mountains, California.
